Introduction to Psychology - College Level

Explore the goals of psychological inquiry, including description, prediction, explanation, and control. Learn how researchers follow the scientific method from hypothesis to testing and application.

Explore observation as a core method in psychology, comparing naturalistic and controlled settings, and explain experimental design, variables, and controls, including random assignment, blind studies, and field experiments.

Explore methods of collecting data in psychology through interviews (structured and unstructured), questionnaires and surveys, focus groups, and observation, while examining reliability, validity, norms, and standardization.

Learn about verbal, nonverbal, and performance tests; group versus individual administration; speed tests with time limits; and case studies with quantitative and qualitative data analysis.

Assess the limitations and relative nature of psychological measurement, and review ethics in research, including respect for persons, privacy, voluntary participation, informed consent, debriefing, and confidentiality.

Trace the evolutionary roots of human behavior and the brain’s role in learning, attention, memory, and problem solving as genes interact with the environment.

Explore the nervous system's structure and its two-part division (central and peripheral), including somatic and autonomic circuits, and how brain regions and hormones shape behavior and experience.

Explore how sensory receptors detect external stimuli, how the eye’s retina and lens process light, and how psychophysics thresholds, color vision, and adaptation shape perception.

Explore auditory sensation and ear anatomy—from pinna and tympanum to the ossicles and cochlea—linking sound waves to neural processing, and examine attention, selective and sustained attention, vigilance, and related theories.

Explore how sensation becomes perception through top-down processing, motivation, and perceptual sets, and examine depth cues, constancies, and illusions that shape recognition.

Explore the nature of learning, distinguishing maturation, habituation, and experience from true learning, and examine classical conditioning and operant conditioning through Pavlov's dog experiments, acquisition, and timing of stimuli.

Delve into operant conditioning, reinforcement types, extinction, generalization and discrimination, alongside observational and cognitive learning, with practical applications for education and organizational settings.

Discover how memory encodes, stores, and retrieves information through sensory, short-term, and long-term stages. Examine memory types—semantic, episodic, procedural, and declarative memory—and how encoding, rehearsal, and retrieval shape learning.

Discover how knowledge is represented and organized in long-term memory, from concepts, semantic memory, and categories to hierarchical networks of nodes, and how retrieval cues and interference shape recall.

Explore the building blocks of thought, including mental images, concepts, and prototypes, and understand problem solving, deductive and inductive reasoning, decision making, judgment, motivation, and mental sets.

Explore the nature of creative thinking, including convergent and divergent thinking, fluency and flexibility, and how language and linguistic relativity shape thought through grammar, semantics, and pragmatics.

Explore how motivation fuels learning and behavior, from physiological and psychosocial motives to needs and drives, and compare emotion theories like James-Lange and Cannon-Bard.
