Study Notes

Scientific Method and Psychology

A hypothesis is a testable and falsifiable prediction.
Empirical science relies on objective measures and the scientific method.
Wilhelm Wundt is considered the first psychologist focused on components of consciousness.

Key Psychological Theories

Abraham Maslow proposed the hierarchy of needs.
Structuralism examines the structure of the mind; Functionalism focuses on mental processes.
Humanistic psychology arose in response to Freud and Watson's reductionism.

Educational and Career Paths

A PhD is required to become a university psychology professor.
Graduates with a BA in psychology often pursue careers outside of marketing and sales.

Research Methodologies

Survey research strengths include ease of generalization.
Longitudinal research can struggle with high attrition rates.
Archival research uses existing records for studies.
Experiments involve manipulating variables to assess outcomes.

Correlation and Variables

A correlation coefficient of 0 indicates no relationship between variables.
Positively correlated variables increase together, while negatively correlated variables exhibit inversely proportional relationships.

Biology of Psychology

Humans have 23 pairs of chromosomes; mutations represent sudden changes in DNA sequences.
Neurons receive signals through dendrites; the central nervous system consists of the brain and spinal cord.
Action potentials involve sodium ions entering and potassium ions exiting the cell, facilitating neuronal communication.

Sleep and Dreaming

Sleep debt occurs due to chronic sleep deficiency, recommended at 7-9 hours for young adults.
Stage 2 sleep is characterized by sleep spindles and K-complexes.
Latent content, according to Freud, refers to the true meaning behind dreams.

Sleep Disorders

Cataplexy is the loss of muscle control associated with narcolepsy.
Somnambulism is another term for sleepwalking.
REM Sleep Behavior Disorder (RBD) involves acting out dreams, leading to potential injuries.

Learning Theories

Stimulants increase blood pressure and induce mild euphoria at low doses; in high doses, they can cause paranoia and hallucinations.
Classical conditioning is a form of associative learning where the stimulus precedes the behavior.
Operant conditioning involves behaviors being influenced by consequences, including positive reinforcement and negative punishment.

Behavioral Techniques

Primary reinforcers include essentials like food and water.
Shaping rewards successive approximations toward a target behavior.
Variable ratio schedules reward unpredictable responses, exemplified by slot machines.

Modeling and Conditioning

The modeling process comprises attention, retention, reproduction, and motivation.
Positive reinforcement strengthens behavior by presenting a pleasant stimulus.
Higher-order conditioning connects a previously learned stimulus to a new stimulus.
