1.1. Psychology Definition

Since the beginning of recorded history, concerns about the nature of human nature have been posed and attempted to be addressed in a variety of fields. Because information of this kind not only facilitates understanding of one's own everyday existence and that of others, but also establishes a foundation for explanations of human existence and has the capacity to influence moral, political, and social activities. The question at the heart of psychology is comparable. Therefore, psychology appears to be an attempt to describe and understand human nature. We'll see in later chapters how psychology is different from other disciplines in terms of how we learn the information needed to respond to this issue. While doing so,

Third generation behaviorism or social behaviorism.

Bandura continued with names such as J. Rotter. Bandura introduced new forms of learning such as learning by observation and modelling, and added a social dimension to the behaviorist approach. It was only in the 1980s that he reached a social cognitive view by defining new concepts such as self- regulation.

Although behaviorism is an approach that has been criticized much later, we owe it to their work to explain basic learning processes such as classical conditioning, operant conditioning, and learning by observation. Information on these topics and the experiments carried out will be explained

in the chapter of your book.

learning

The importance

that behaviorism attaches to observable/measurable human characteristics and systematic analysis still continues as a basic approach, and this understanding can be used when studying concepts such as mind, consciousness and awareness, which are ignored by them today.

At the same time, it should not be overlooked that the critique of behaviorism is the source of the cognitive approach, so that an ever-widening viewpoint about human beings can be obtained.

1.1.1. Gestalt School

Gestalt psychology originated in Germany in the early 1900s by Max Wertheimer (1880- 1943), Kurt Koffka (1886-1941) and Wolfgang Köhler (1887-1967). The word Gestalt means “whole”, “form” in German.

However, since there is no word that fully corresponds to it in any language, the word "gestalt" is used exactly in all languages.

Gestaltists opposed Wundt's understanding of structuralism and behaviorism to analyze the mind by dividing it into atoms (parts). According to them, life cannot be divided into its elements; When examining life, the relationships and interactions of the elements should be taken into account. Our Lives It creates patterns or organized structures, events in one part of the field are affected by events in the other part. For example, a gray piece of paper is light on a black background and dark on a white background. So it is the relationships between the elements that matter. An important principle defining the understanding of this school is the expression "the whole is more than and different from the sum

of its parts". For example, when we listen to a piece of music, we perceive a whole melody, not individual notes.

The Gestalt school left an indelible mark on psychology with their work in areas such as perception, learning, personality, social psychology and motivation. The results of his studies in the field of perception are still among the basic information in introductory psychology books.

In the section of sensations and perception, we will examine the researches of the Gestalt school and the principles they found. In addition, it should not be overlooked that some of the ideas they put forward

influenced the cognitive approach or the humanistic approach that emerged in the second half of the 20th century.

1.1.2. Psychoanalysis and Sigmund Freud (1856 -1939)

In the years when psychology as a science was just beginning to be established, S.Freud, who was actually a neurologist, developed a treatment technique called "psychoanalysis" as a result of his clinical studies. However, Freud's contributions to the history of human thought are not limited to this.

Freud is one of the few scientists who is known all over the world by people who are not interested in these fields, and who has influenced many branches of science with his thoughts. He underlined that people do not consist only of reason and logic, saying that people are not aware of and actually have a subconscious mind that directs their behavior. In order to understand the shockingness of this idea, which may seem quite ordinary to us now, it is necessary to grasp the philosophical and scientific background of the 19th century. Freud had a detailed theory of the genesis of human and mental illness, and psychoanalysis, a treatment technique, still has followers in the clinical field.

His psychoanalytic approach has had an impact on psychology in many ways. For example, his view that early childhood experiences shape adult human behavior has been a source of impetus for developmental psychology research. What we call the psychodynamic approach today, in which behavior is explained within the framework of past experiences and impulsive sources; The approach, which accepts that actions occur with an effort to resolve conflicts between instincts and social requirements, is built on Freud's views. There are also personality theories developed on the basis of the psychoanalytic approach.

Even though the scientificity of the theories and concepts on which the psychoanalytic approach is based is open to debate, Freud left a form of treatment and a unique human vision that is still in use almost 100 years after its introduction. In addition, it should be admitted that the consciousness researches carried out today using re-experimental methods also need the concept of the subconscious that was put forward by him.

1.1.3. Humanistic Psychology

Humanistic psychology emerged in the 1950s as a reaction to psychodynamic and behavioral approaches. It is possible to see the effects of existential philosophy on the basis of this approach. According to the humanistic approach, people determine their behavior based neither on instinctive sources, as psychodynamicists say, nor on environmental sources, as behaviorists say. Humans are beings who are conscious of their own existence, naturally oriented towards good and have the ability to choose. Man's goal should be to realize his own potential; In order to achieve this, it is necessary to work on developing free will, spontaneity and the creative power of the individual by believing in the integrity of human nature. Self- actualization theory put forward by A. Maslow (1908-1970) and the work of C. Rogers (1902-1987) played a major role in the development of this approach. Rogers also introduced the psychotherapy approach called "client-centered therapy". Like this

humanistic psychology has remained a point of view used in clinical fields rather than a model that explains the whole human being. This approach has been effective until the 1970s, but the emergence of the cognitive approach and the emergence of a new understanding of human has led to new treatment techniques.

1.1.4. Cognitive Approach

The cognitive approach emerged as a critique of behaviorism in the 1970s.

The main source of these criticisms has been that the behaviorist approach treats the mind as a black box and leaves it out of examination because it cannot be observed directly. In other words, they based their main objection point on the fact that all human behaviors are too complex to be explained by learning processes.

Cognitiveists have said that mental processes such as thinking, remembering, understanding, problem solving, and memory should be examined. Such processes cannot be observed directly, but behaviors such as problem solving and remembering that reveal these processes can be observed and inferences can be made about these processes by examining these observations. At the same time, human thought is a factor influencing his behavior; that is, behaviors cannot be explained solely as a result of stimuli from the environment.

Cognitiveists have validated these basic objections through empirical research. The cognitive approach needed to model the human mind and used the computer metaphor, which is very appropriate for the 20th century.

Although it is accepted that the cognitive movement was initiated by G. Miller (1920-2012) and U. Neisser (1928-2012), it was developed and evolved together by many researchers, slightly different from previous approaches. This understanding has been the source of many new researches and opinions in almost every sub-field of psychology. From the point of view of this understanding, many researches have been carried out, theories have been developed and a considerable knowledge has been created in many areas such as development, personality, abnormal behaviors, social behaviors, and treatment practices.

However, as the name suggests, this approach puts too much emphasis on the study of cognitive processes. At the same time, the limitations of modeling the human mind with the computer metaphor have begun to be expressed more and more. The cognitive approach, which still continues as a dominant understanding today, has been exposed to criticism from the side and its deficiencies in explaining more and more people are revealed.

1.1.5. Evolutionary Psychology

Evolutionary psychology investigates the origins of certain behaviors and mental processes and examines what adaptive advantages they may have provided in the course of evolution.

In doing so, it draws on data from history, evolutionary biology and anthropology. By focusing on the environmental factors in which the human brain evolved, researchers try to determine what adaptation requirements were in a particular historical time. These adaptation requirements are either

Once the challenges specific to that historical time have been identified, evolutionary psychologists examine how mental mechanisms and psychological adaptations work to resolve such issues. With this approach, a wide variety of behaviors such as helping, mating, choosing a mate, jealousy, parental attitudes have been examined and interesting perspectives and theories have been put forward.

1.4.5. Where Is Psychological Science Heading?

Today, although the effects of cognitive psychology as the mainstream of psychology continue, the points that this approach is insufficient to explain are increasingly revealed. The cognitive approach envisioned the human mind as a cognitive/mental system at its core. However, some researchers say that this approach replaces the behaviorists' black box with an empty-headed processor, but the human mind is not just that. The modeling of the human mind using the computer metaphor overlooks the fact that the human being is a being who can think on his own thoughts.

On the one hand, the results from developmental psychology studies that “people can understand the intentions, desires and thoughts of others in the very early years of life and act accordingly” open

new horizons by showing that human understanding is not just cognitive elements. The results that this understanding develops by cooperating and cooperating with other people seem to reorganize our perspective towards the sources of the human mind and behavior.

On the other hand, gradually developing behavioral/cognitive neuroscience researches provide the basis for the development of new understandings by examining the brain processes that reveal sensation, perception, thinking and emotions. At the same time, research on awareness and consciousness is increasing and striking results are beginning to be revealed. We will review all of this new research in later chapters.

In the near future, the science of psychology seems to be preparing to make a leap in understanding the human being by creating more complex models in which all aspects of the human being can be considered together and with an interactive understanding. With the words of Ebbinghaus, the science of psychology, which has a long history but a short history, focuses on human characteristics that seem more and more complex, but while doing this, it continues to use controlled and systematically conducted observations and experiments that distinguish it from other branches.

What Did We Learn In This Chapter?

The science of psychology can be defined simply as the study of people's behavior and mental processes using scientific methods. The purpose of this review is to describe behaviors, mental processes and the factors that affect/are affected by them, to reveal how it happened and to explain its causes. When conducting research in the field of psychology, we want to describe, explain, predict the behavior and mental processes of people, and make adjustments for the benefit of humanity by making use of our conclusions. The diversity of human behavior has necessitated the formation of specialized sub-fields on various aspects of human beings such as developmental psychology, experimental psychology, social psychology, clinical psychology. The history of psychology as a science begins with the “Psychology Laboratory” founded in 1879 by Wilhelm Wundt in Leipzig, Germany. Since this date, it is seen that a considerable knowledge has been reached by developing and strengthening with different perspectives and understandings that actually complement each other. In Ebbinghaus's words, psychology, which has a "long history but a short history", focuses on human characteristics that seem more and more complex, but while doing this, it

2.1. INTRODUCTION

In the first part, we mentioned that the difference between Psychology and some other disciplines that try to clarify the questions about the nature and structure of the human stems from the ways of obtaining information. Since its birth as a branch of science, psychology has aimed to produce information about human beings by using the scientific method. In this respect, in order to understand how psychology studies human beings, it is necessary to first understand what science, scientific method and scientific knowledge are. In this section, we will learn both the general features of the scientific method and the features of psychology research.

2.1. What Exactly Do We Mean When We Talk About Science, the Scientific Method, and Scientific Knowledge?

2.1.1 The Scientific Method and the Scientific Discipline

Ever since they came into being, humans have been curious about the events that are taking place in the world they occupy, and they have desired to have those events explained to them while also speculating about the future. The necessity has inspired humanity to develop a wide variety of solutions. For instance, astrology, which involves deducing what is going now and what will happen in the future by observing the stars, and fortune telling are both methods that are commonly employed today despite the fact that they have been around for thousands of years. Neither of these things, however, are scientific. In this section, we will discover what sets the scientific method apart from other activities of this kind.

The integrity of the information that has been gained via the use of methodical research procedures is what we mean when we say that science exists. The goal of the development of science throughout history has been to provide a method and conceptual framework that are consistent, dependable, and logical in order to make our experience of nature more intelligible. When we talk about science in our day-to-day lives, we are referring to both a technique that can be used to the pursuit of new information as well as a body of information that may be modified as a result of new discoveries obtained via the application of this approach.

In order to find answers to their inquiries about the natural world, scientists in every subfield of the discipline use the scientific method. This is the defining characteristic of scientific endeavors. On the other hand, each and every endeavor that makes an attempt to comprehend and clarify makes use of its own technique, which may be seen as a means of accumulating and creating information. For instance, in coffee fortune telling, a strategy is used, such as comparing semi-specific forms to something and describing the feelings that these shapes trigger in the reader. In point of fact, some figures have come to be interpreted in a certain way throughout time (such as the interpretation of the bird as news), and this work is an attempt to organize such meanings. A manner of collecting information does not automatically qualify as scientific just because it makes use of a certain method or approach and benefits from a semi-systematic review. The first characteristic that distinguishes the scientific method from other techniques is that it collects data in a sequential, methodical, and objective manner in order to get an understanding of the observed occurrences. This is what distinguishes the scientific method from other approaches. Nevertheless, this quality by itself is not sufficient. Conducting methodical research to understand the underlying phenomenon of a series of similar events and determining the limits of the series of events to which the detected phenomenon can be generalized is the second feature that makes the scientific method scientific. This feature is characterized by the fact that the scientific method is scientific.

2.1.2 What are the Goals of the Work Done in the Scientific Field?

A scientific endeavor serves five different purposes:

a) To properly describe (description and describe) natural events, or, to put it another way, to ascertain precisely what they are;

b- Providing an explanation, or explanation, of natural occurrences, including an explanation of why and how they occur;

c) The development of consistent knowledge frameworks, such as hypotheses or models that can account for a set of observed occurrences;

d) To make predictions about new events by using explanations and theories or models as a basis, and then to test these predictions;

e) Using these forecasts as a basis for making plans that would ultimately be beneficial to mankind.

In point of fact, there is a gradualism between both objectives. It is possible for a researcher to begin their work at a different stage depending on the amount of gathered information in the topic in which they are working. If past researchers have characterized, hypothesized, and explained existing phenomena in that discipline, then current researchers may be interested in evaluating whether existing ideas explain new occurrences. In situations when there is a lack of information, it is necessary to focus on describing or explaining the facts that already exist. Sometimes there are several competing explanations for the same phenomenon, as well as multiple competing models for the same topic. After that, it would be proper to begin working on what may be the most suitable explanation for the situation.

It is possible for researchers to spend decades laboring over the same problem in order to either explain it or verify the predictions made by an existing model. As a result, scientific endeavor is almost always the result of a cumulative process that is carried out by a large number of researchers rather than the creation of a single individual. To ensure that the goals of scientific endeavors are met, it is imperative that researchers continue to build upon and disseminate the information that they have obtained throughout the course of their careers to subsequent generations. Sometimes, an innovation that seems to have been developed by a single individual was in fact made feasible by the work (or even the unproven theories) of hundreds of researchers who came before him. Obtaining accurate information calls for a procedure that is carried out continuously and in which fresh pieces of data are layered atop the ones that came before them. As a result, any errors or gaps in the earlier data become apparent as the process continues.

2. What Does It Mean to Have Scientific Knowledge? 3. What Does It Mean for Knowledge to Be Scientific?

There are very few people in our nation who have not, at some point in their lives, had their coffee fortune told by someone else. However, it is well knowledge that the statements made by the fortune teller have no foundation in scientific fact. Sometimes the words of the fortune teller or the interpretations of the astrologers might even turn out to be accurate. But even if such were the case, we are aware that what is being presented is not information based on scientific research. Then, what are some of the characteristics that set scientific knowledge apart from other types of information?

The information that constitutes scientific knowledge is not the result of an individual's opinions and beliefs; rather, it is information that has been accumulated through experimentation and observation and is founded on objective facts. There is no correlation between the fact that a piece of information is accurate or right and the fact that it is scientific knowledge. The methodology behind the accumulation of scientific knowledge is the defining characteristic that sets it apart from other types of information. Scientific knowledge is information that can be observed by anybody (you need to take into consideration not just the senses, but also devices such as microscopes or tests), that can be measured, that can be tested, that can be repeated, and that can be transmitted.

Sometimes we may have opinions or ideas that we have arrived at via our intuition, but we are unable to clearly describe why we came to those conclusions. These kinds of occurrences are just as likely to happen in the scientific community, and occasionally even intuition is the driving force behind discoveries. But what differentiates a scientist from a fortune teller in this context is that the scientist has an obligation to test the validity of these intuitions.

carrying out one's study in accordance with the scientific method, which involves carrying out one's observations and experiments in a methodical manner.

2.2. What Is the Proper Way to Plan and Execute a Scientific Experiment?

The practice of examining problems pertaining to the natural world with a scientific mindset and searching for solutions via the use of the scientific method is known as scientific research. In an earlier section, we discussed how the first component of the scientific method is to gather data in order to get an understanding of observable occurrences by working one at a time, in a methodical manner, and with an objective perspective. Systematic investigation to identify the underlying phenomena of a sequence of identical incidents is an essential component of the second characteristic that is significant to us in this context.

During the course of psychological research, facts are gathered via rigorous and methodical observations; hypotheses are established to explain these findings; On the basis of these theories, fresh predictions are formulated, and the accuracy of these forecasts is then checked in a methodical manner, once again on the basis of the data.

As a result, in order to get an understanding of the procedure, we do not look into the following two primary concerns: first, how the research process was initiated, organized, and carried out; and second, the types of data collecting techniques that are used in the field of psychology. This part will focus on humans since psychology is the subject of our discussion. It will be illustrated via examples, as well as the challenges associated with doing research on individuals.

2.2.1. How Should We Structure the Research Procedure?

The process of designing a research study is done in sequential steps. A comprehensive and careful investigation is required at every stage, beginning with the disclosure of the research topic and continuing with the dissemination of the data acquired to the scientific community.

Every piece of research starts with a question; put another way, its ultimate goal is to answer a question. However, a scientific investigation has to start with a topic (or issue) that can be investigated using scientific methods.

People have a lot of questions, such as: What sort of life is waiting for us after death? Is there life outside of this world? Are the physical qualities of intelligent creatures living outside of this world comparable to ours? At this time, we are unable to address and investigate such concerns using scientific methods. Because, with the information that is now available, it is not feasible to identify some of them as true and to construct a research study that is observable, quantifiable, and tested for others.

But here's something to think about: in 1865, when Jules Verne was writing his book "A Journey to the Moon," he posed the question, "Is there life on the moon?" The topic could not be answered using scientific methods since it was impossible to obtain the necessary data, such as by traveling to the location in question, collecting samples, and analyzing the results. The topic of whether or not there is life on the moon was addressed by the author Jules Verne in the form of a book, in which he attempted to provide both a response and a dream. As a result of the cumulative scientific study of scientists who followed this ambition, we now have the information and the equipment required to provide a scientific response to this issue. This acquisition of knowledge and equipment took place over the course of the last 100 years. So today

Questions that now seem unanswerable by scientific means may one day be amenable to investigation. Every piece of scientific investigation, however, has to start with a topic or issue that can be investigated in the here and now.

It is vital to do a little bit of effort on the questions that we ask based on our observations or intuitions from our day-to-day lives if we want such questions to be researchable. You will discover an example of how ordinary queries might be converted into a research topic for a scientific study in the pages that follow.

Next, the researcher will need to hazard a guess or make an educated estimate on the response to the question that he posed. This is known as the hypothesis, and it is the second phase in the process of doing research. After the issue and hypothesis have been identified, the research procedure may then be constructed in line with those elements while also taking into account the most recent information available on the topic. It is necessary to determine the steps on whom the study will be carried out, which measurement / evaluation methods will be used, how the type / design of the research will be, how the data collection process will be organized, and which statistical techniques the collected data will be analyzed using. In order to accomplish this, it is necessary to determine the steps on whom the study will be carried out. Following the completion of the planning stage for how each step will be carried out, it is time to gather data. After then, the information that was gathered is processed, and the results are looked through. As a result, we check to see whether the response we provided to the question we posed is accurate. If our response cannot be validated and there are no issues with the methodological arrangements of the study, then it is vital to continue working on other potential solutions to this topic. mainly due to the fact that every hypothesis is a short-term solution idea until it is backed by the results of investigation. The outcomes of the researcher's work should be made available to the scientific community regardless of whether or not they conform to the expectations that were set for the study. Making talks at congresses that are relevant to the area and publishing scientific research papers in academic journals are the two most effective ways to accomplish this goal.

2.2.2. From an Everyday Mystery to a Subject of Scientific Investigation

It is a topic that may be seen or thought about by a great number of individuals in their everyday lives.

Let's get started with a query and explore how we can transform it into a research process for the scientific community.

If you consume coffee as you study, you may find that you are able to concentrate on your job for longer periods of time. The question thatmcyomsteusdytotiymoeu? o"Dulodeas pdsriynckhinoglocgoisftfedeopifrohleong wanted to construct a study in order to solve the question that you posed. r "mNinodw,mwahyabtew, o"Dulodeas pdsriynckhinoglocgoisftfedeopifrohleong

To begin, this question, which was posed in a more casual manner, has to be reformulated as one that can be answered by doing research. Reading and thinking about how to frame the question in a manner that is observable, quantifiable, testable, and repeatable is the most suitable method to proceed with this task. Let's begin to think, presuming that we've decided that this is a question that merits an answer after having read and studied an adequate amount of previously conducted research; having developed ideas about what potential research variables are and how they can be addressed; and having read and studied an adequate amount of previously conducted research.

Consuming coffee and devoting a significant amount of time to study are the two factors that are posited to have an effect on one another within the context of this inquiry.

At this point, we need to give some thought to the precise meanings of both variables.

When it comes to studying for an extended period of time, being able to read a text without being distracted, that is, not being distracted, that is, the duration during which attention can be kept, is what is indicated by "ability to read a text without becoming distracted."

As a result, "attention time" can be a variable that we use to describe one of our other variables.

Consuming coffee is the other factor to consider. It would seem that drinking coffee is something unique, something that can be comprehended in the same manner by each and every person. In order to create an experiment, however, we need answers to questions such as which coffee, how much coffee, and what sort of coffee we will be using. because the ability of subsequent researchers to reproduce the findings of this study is solely dependent on this factor. One method is to really use coffee and to maintain consistency in aspects such as the kind of coffee, the quantity of coffee consumed, and the intensity of the coffee. However, one approach would be to describe the coffee consumption variable as the amount of caffeine consumed in milligrams (mg), assuming that we have learnt from our research what the chemically active component in coffee is and that we believe the caffeine in coffee has the potential to be beneficial. This is a more reliable method because, while the study is being carried out, any variables that may skew the results, such as whether or not individuals enjoy coffee and whether or not they drink all of the coffee they are given, will be removed. In this scenario, we will be able to provide caffeine in a variety of different forms, such as tablets or injections, for instance.

At this point, the question that we wish to investigate is as follows: "Does 5 mg of caffeine increase attention span?" As the variables are stated, the subject seems to be getting closer and closer to being a research problem that can be analyzed. Now that this has been brought to our attention, we need to consider: how do we know that our attention span has increased?

This problem might be thought of as having two aspects: the first of which is how we measure attention span. As psychologists, we are able to make use of one of the assessments that determines the degree of attention that is being paid at the moment. If there isn't already a test like this one, and if we understand how attention works, then it's likely that we could come up with one on our own. Let's say that we are utilizing an already developed test. For the sake of this discussion, we will refer to an individual's attention span as their top score on the AB test.

Based on whether or not the total scores have improved, we shall decide whether or not more time has been allotted. In light of this, our inquiry was as follows: "Does an intake of 5 mg of coffee boost scores on the AB attention test?"

The second aspect of this problem is how we can determine whether or not consuming caffeine raises levels of attentiveness. The first method that comes to mind is to give caffeine to only one of the groups and not the other, then to evaluate both of the groups' levels of attention afterward. In this situation, our query is as follows:

“5mg. The results of the AB attention test for the group that was given caffeine and the group that was not given caffeine

Existe-t-il des différences notables entre

With this framework, our inquiry has developed into a matter that requires scientific investigation and has become a challenge for researchers.

The potential response to the inquiry that we posed will be the focus of the second step, which will be the formulation of the hypothesis. Within the context of this illustration, we are able to derive our hypothesis from our observations. Everyday

a potential response with the sentence may be "yeah, it does, I work better." This is one possibility. However, the response to the issue that we have posed in a language that is amenable to research need to likewise be appropriate for it. In this particular instance, our working hypothesis is "5 mg. On the AB attention test, there is a clearly discernible gap between the results obtained by the group that was given caffeine and those obtained by the group that was not given caffeine.

The third step is to figure out how to answer this issue using a research setting, or more specifically, to construct the methodology component of the study. Since we are going to compare the results of the attention test that were obtained by the groups that did and did not take caffeine, we should have two groups. One of these groups should be given caffeine, and the other should not. After a predetermined amount of time, the attention test should be administered to both groups. The procedure may be summarized as follows.

Having said that, there are still a lot of things to think about. If people in a group already have extended attention spans, then how can coffee be the cause of the difference in performance across the groups? After that, we need to determine the people in both groups' levels of attention before administering caffeine, then we need to decide whether or not to provide caffeine, and last, we need to reevaluate their levels of attention. In such case, there is no way for us to know for certain that the difference is due to caffeine.

As a result of this, we need to build the experimental setting while also taking into consideration a wide variety of potential disruptors and making judgments about them. For example, how to control factors like hunger and satiety, which may affect both the attention level and the duration of caffeine's effect (for instance, the pre-test after breakfast was given to the subjects who were provided with an empty stomach in the morning, then the administration of caffeine to the experimental group, waiting for it to mix into the blood, and the post-test were given to the other group. at the end of the same period as the post-test) should be considered. In this experiment, the subjects were provided with Because this is only an example, we are not going to go into detail about the various variables that might potentially influence the outcomes of this experiment throughout the process of identifying participants, designing the experiment, and carrying it out, and that thus need to be controlled. If, on the other hand, we were really doing research, we would need to consider more specifically within the scope of our existing information and the context of our own experiences in order to make a number of modifications that would strengthen the validity of the findings.

Following the completion of the data gathering, the next step is to do an analysis of the data using the most relevant statistical methods. Because our research question is formulated in such a way as to investigate the differences between the two groups, it is possible to carry out a statistical test—a t-test, for the purpose of this illustration—in order to ascertain whether or not the difference is significant.

2. 4. The Approaches and Methods That Are Employed In Psychological Research

What do you mean by that?

2.4.1. Different Approaches to Conducting Research in the Field of Psychology

When doing research, we have the ability to gather information at varying levels by using one of three distinct methodological configurations: descriptive, correlational, or experimental approaches.

A type of research known as descriptive research exposes the state of affairs as they currently are, defines and contrasts the key aspects of the facts, and reveals the situation as it currently stands. It should be emphasized that this form of study belongs to the first of the purposes of scientific work.

The purpose of correlational research is to investigate the links or correlations that exist between different observable occurrences. In this instance, because we will be defining the present circumstance in its existing state, we will, in essence, have carried out descriptive study. However, because the connections between the defined phenomena are investigated, and because results that can test the existing models can be obtained from such data by conducting more complex statistical analyses, they can be discussed under a separate heading that is referred to as "correlational studies." Studies that just look at correlations don't provide us enough information to make any conclusions regarding cause and effect relationships. An illustration of this scenario is something that we can provide for you. The volume of ice cream served was shown to have a very strong association (correlation) with the number of persons who drowned at sea, according to the findings of a researcher. A significant connection may also be established between the number of people who drown and the number of ice creams and beach slippers that are sold. A comparable high correlation can also be found between the number of people who drown and the number of swimsuits that are sold. In spite of the fact that there is a strong correlation between them, there is not a causal relationship between these variables, which is something that we can all deduce through logic. For instance, we do not believe that the consumption of ice cream is the cause of people drowning in the ocean.

There is a further factor that has an effect on all of this, is the cause of all of it, and is the cause of all of the other factors (in this example, the high temperature of the air). As a result, the link between variables is an example of an inadequate and insufficient degree of knowledge when it comes to discussing the connections between causes and effects.

On the other hand, experimental research gives us the opportunity to achieve more advanced research goals, such as explaining the factors that contribute to a phenomenon or putting hypotheses, models, or predictions to the test. We are unable to arrive at conclusions that discuss cause and effect relationships unless we first conduct research that is empirical in nature. The ability of the researcher to control the variables and potential disruptors that are part of the research question is the basis for the level of confidence that can be placed in the findings obtained from studies of this kind. Because only under these circumstances does a circumstance arise in which we consider it possible that it could be the cause of a phenomenon.

Because of this, we have the chance to determine whether or not the other information or circumstance is genuinely effective.

In the illustration that was provided in the subsection titled "From a daily question to a researchable question," a straightforward plan for an experiment was developed. It is possible to design experimental studies at various levels, such as semi-experimental and experimental levels, in terms of the reliability of the knowledge that is acquired.

Despite this, we are not going to get into the specifics.

How do we go about selecting the research approach that we will use when designing a study?

The nature of the question or problem that we want to investigate is the single most important factor that will determine the kind of research that we design. The amount of experience and expertise that has been accumulated in the field is another factor that plays a role. If sufficient descriptive and correlational results have been amassed and consistent explanations can be obtained, then empirical research should be favored. Empirical research should be preferred if sufficient descriptive and correlational findings have been accumulated. Because it is only then that we will be able to make conclusions regarding the factors that led to the behavior and/or put our hypotheses to the test.

Because human behavior is always shifting and becoming more complex, the discipline of psychology should make regular use of descriptive research. For instance, in order to explain human behavior in social media environments, which is a newly emerging field, descriptive and correlational studies are required to show the nature of these behaviors and their connections with other human characteristics. This is necessary in order to explain human behavior.

Due to ethical considerations, it is not possible to conduct experimental studies on humans in certain fields. These fields include: For instance, it is not possible for us to conduct an experiment to investigate how the mental development of children is affected when they are denied love and affection. Because in this scenario, we would have to take two sets of newborn babies and raise one group of them by excluding love and compassion from their lives. If there was such an effect, we would be doing harm to humanity by fostering the growth of people whose minds are not fully formed. It should be obvious that such an experimental order cannot be carried out in a conscientious manner. Descriptive research is the only method that will allow us to conduct studies on this topic; this means that we will have to examine children who grew up in such environments for a variety of reasons and do so under natural circumstances.

2.4.2. Methods of Data Collection Utilized in the Field of Psychology

The majority of the data that we use in psychological research comes from actual people. There are a variety of reasons why studies involving animals are carried out. When collecting data, we might make use of things like observations, interviews, questionnaires, scales, tests, and other specialized tools and activities. Let's take a moment to quickly go over some of the key aspects of these methods.

2.4.2.1. Observation

One of the most important methods of data collection that psychologists make use of is observation, which is a way of obtaining information that each of us uses frequently in our day-to-day lives. On the other hand, there are a few key differences between the observations made in the course of data collection and the observations that we make in everyday life. In order for observations to be used as a method of data collection, they first need to be recorded and then assessed in relation to the function that is being investigated. Naturalistic observation and systematic observation are the two main categories under which observations can be categorized in general.

In the natural state of observation, the researcher simply observes without participating in any way, taking great care to maintain the conditions under which the observation is not carried out. Through the use of this method of observation, we are able to see every facet of how any function, behavior, or situation occurs in its natural environment. It serves as an efficient jumping off point for research a lot of the time.

The behavior, function, or activity of systematic observation is something that is predetermined. It entails keeping an eye on things and making notes about them in accordance with a predetermined strategy or method.

Using ticker lists, observations should be graded based on a number of characteristics, including whether or not the relevant function/behavior or condition is present, how frequently it occurs, how severe it is, and how well it is performed. Additionally, it may be feasible to preserve observation diaries under certain circumstances. For instance, when we notice things in their natural environment, maintaining a journal of our observations might be a practical approach to document them.

Taking audio or video recordings of observations is widely considered to be the standard practice in today's society.

Markup lists and taxonomies are used here in order to do the scoring and evaluation of such data in relation to the applicable function.

There are a lot of things that can put a damper on the reliability of the information that is obtained through this method, despite the fact that the observation technique is an extremely efficient way of gathering data.

In many contexts, observer bias is the most significant factor that contributes to negative outcomes. today image

Observing by taking the record and evaluating these records by independent observers and then examining the reliability between raters helps to eliminate these factors. In addition to this, the correct and sufficient preparation of the instruments by which we analyze the observations also contributes to an improvement in dependability. An important point to be considered in observations is to ensure that the observed environment and time of observation are representative in terms of the emergence of the relevant function.
