Introduction to Psychology

In operant conditioning, the delay of reinforcement refers to the time gap between a response and the subsequent reinforcement, which typically weakens the association.

Primary reinforcers are stimuli that are naturally reinforcing because they satisfy biological needs, such as food, water, and warmth.

Max Wertheimer is one of the founders of the Gestalt school of psychology, which focuses on perception and the idea that the whole is greater than the sum of its parts.

Abraham Maslow is a well-known humanistic psychologist, famous for his hierarchy of needs and focus on self-actualization.

Sensation is the process by which our sensory receptors and nervous system receive and represent stimulus energies from our environment.

A variable ratio schedule provides reinforcement after an unpredictable number of responses, which is characteristic of commission-based pay where the number of sales required for a reward varies.

Freud's psychoanalytic theory posits that neuroses arise from repressed memories, motives, and conflicts residing in the unconscious mind.

In psychoanalysis, resistance refers to the patient's unconscious attempts to block the process of revealing repressed memories or painful feelings.

Attributing an action to the characteristics of the situation (the food needing salt) rather than the person's internal traits is an external or situational attribution.

A reference group is a group that individuals use as a standard for evaluating themselves and their own behavior.

In Pavlov's experiment, the dog's natural, unlearned response to food (the unconditioned stimulus) is salivation, making it the unconditioned response.

Classical conditioning occurs when a neutral stimulus is paired with an unconditioned stimulus until it elicits a conditioned response.

In this scenario, the snake (initially neutral) became associated with the loud noise (unconditioned stimulus), making the snake the conditioned stimulus (CS).

Punishment is most effective when it is immediate, consistent, and intense enough to discourage the behavior. Delayed or inconsistent punishment fails to create a strong association between the behavior and the negative consequence.

An IQ of 100 represents the mean score for a given age group. It indicates that an individual's mental age is equal to their chronological age.

General intelligence tests, often referred to as g-factor tests, are designed to measure a broad spectrum of cognitive abilities rather than specific skills.

Standardization in testing involves creating uniform procedures for administration and establishing norms, which are scores derived from a representative sample to provide a basis for comparison.

Phenylketonuria (PKU) is a metabolic disorder that causes intellectual disability if left untreated, but it can be managed by strictly following a special diet low in phenylalanine.

The classic formula for calculating the Intelligence Quotient (IQ) is Mental Age (MA) divided by Chronological Age (CA), multiplied by 100.

Naturalistic observation involves observing and recording behavior in its natural setting. Its primary goal is to provide a detailed description of what is happening rather than explaining why or predicting future outcomes.

In an experiment, the dependent variable is the factor being measured or tested for change. Since the study measures IQ scores to see if ginseng has an effect, the scores are the dependent variable.

The cerebral cortex is the part of the brain responsible for higher-order functions like reasoning, planning, and language. It is significantly more developed in humans compared to simpler organisms like carp.
