AP Psych Unit 4

Habituation

Habituation

decreasing responsiveness with repeated stimulation. As infants gain familiarity with repeated exposure to a visual stimulus, their interest wanes and they look away sooner.

Learning

the process of acquiring new and relatively enduring information or behaviors

Associative Learning

learning that certain events occur together. The events may be two stimuli (as in classical conditioning) or a response and its consequences (as in operant conditioning).

Stimulus

a change in an organism's surroundings that causes the organism to react

Respondent Behavior

behavior that occurs as an automatic response to some stimulus

Operant Behavior

behavior that operates on the environment, producing consequences

Cognitive Learning

the acquisition of mental information, whether by observing events, by watching others, or through language

Classical Conditioning

a type of learning in which one learns to link two or more stimuli and anticipate events

Behaviorism

the view that psychology (1) should be an objective science that (2) studies behavior without reference to mental processes. Most research psychologists today agree with (1) but not with (2).

Neural Stimulus (NS)

in classical conditioning, a stimulus that elicits no response before conditioning

Unconditioned Response (UR)

In classical conditioning, the unlearned, naturally occurring response to the unconditioned stimulus (US), such as salivation when food is in the mouth.

Unconditioned Stimulus (US)

in classical conditioning, a stimulus that unconditionally—naturally and automatically—triggers a response.

Conditioned Stimulus (CS)

in classical conditioning, an originally irrelevant stimulus that, after association with an unconditioned stimulus (US), comes to trigger a conditioned response.

Conditioned Response (CR)

in classical conditioning, the learned response to a previously neutral (but now conditioned) stimulus (CS)

Acquisition

In classical conditioning, the initial stage, when one links a neutral stimulus and an unconditioned stimulus so that the neutral stimulus begins triggering the conditioned response. In operant conditioning, the strengthening of a reinforced response.

Higher-Order Conditioning

a procedure in which the conditioned stimulus in one conditioning experience is paired with a new neutral stimulus, creating a second (often weaker) conditioned stimulus. For example, an animal that has learned that a tone predicts food might then learn that a light predicts the tone and begin responding to the light alone. (Also called second-order conditioning.)

Extinction

the diminishing of a conditioned response; occurs in classical conditioning when an unconditioned stimulus (US) does not follow a conditioned stimulus (CS); occurs in operant conditioning when a response is no longer reinforced.

Spontaneous Recovery

the reappearance, after a pause, of an extinguished conditioned response

Generalization

the tendency, once a response has been conditioned, for stimuli similar to the conditioned stimulus to elicit similar responses

Discrimination

in classical conditioning, the learned ability to distinguish between a conditioned stimulus and stimuli that do not signal an unconditioned stimulus

Operant Conditioning

a type of learning in which behavior is strengthened if followed by a reinforcer or diminished if followed by a punisher

Law of Effect

Thorndike's principle that behaviors followed by favorable consequences become more likely, and that behaviors followed by unfavorable consequences become less likely

Operant Chamber

in operant conditioning research, a chamber (also known as a Skinner box) containing a bar or key that an animal can manipulate to obtain a food or water reinforcer; attached devices record the animal's rate of bar pressing or key pecking.

Reinforcement

in operant conditioning, any event that strengthens the behavior it follows

Shaping

an operant conditioning procedure in which reinforcers guide behavior toward closer and closer approximations of the desired behavior

Discriminative Stimulus

in operant conditioning, a stimulus that elicits a response after association with reinforcement (in contrast to related stimuli not associated with reinforcement)

Positive Reinforcement

Increasing behaviors by presenting positive stimuli, such as food. A positive reinforcer is any stimulus that, when presented after a response, strengthens the response.

Negative Reinforcement

Increasing behaviors by stopping or reducing negative stimuli, such as shock. A negative reinforcer is any stimulus that, when removed after a response, strengthens the response. (Note: negative reinforcement is not punishment.)

Primary Reinforcer

an innately reinforcing stimulus, such as one that satisfies a biological need

Conditioned Reinforcer

a stimulus that gains its reinforcing power through its association with a primary reinforcer; also known as a secondary reinforcer

Reinforcement Schedule

a pattern that defines how often a desired response will be reinforced

Partial (Intermittent) Reinforcement Schedule

reinforcing a response only part of the time; results in slower acquisition of a response but much greater resistance to extinction than does continuous reinforcement

Fixed Ratio Schedule

in operant conditioning, a reinforcement schedule that reinforces a response only after a specified number of responses

Variable Ratio Schedule

in operant conditioning, a reinforcement schedule that reinforces a response after an unpredictable number of responses

Fixed Interval Schedule

in operant conditioning, a reinforcement schedule that reinforces a response only after a specified time has elapsed

Variable Interval Schedule

in operant conditioning, a reinforcement schedule that reinforces a response at unpredictable time intervals

Punishment

an event that decreases the behavior that it follows

Biofeedback

a system for electronically recording, amplifying, and feeding back information regarding a subtle physiological state, such as blood pressure or muscle tension

Preparedness

a biological predisposition to learn associations, such as between taste and nausea, that have survival value

Instinctive Drift

tendency for animals to return to innate behaviors following repeated reinforcement

Cognitive Map

a mental representation of the layout of one's environment

Latent Learning

learning that occurs but is not apparent until there is an incentive to demonstrate it

Insight

a sudden and often novel realization of the solution to a problem

Intrinsic Motivation

a desire to perform a behavior effectively for its own sake

Extrinsic Motivation

a desire to perform a behavior to receive promised rewards or avoid threatened punishment

Problem-Focused Coping

attempting to alleviate stress directly by changing the stressor or the way we interact with that stressor.

Emotion-Focused Coping

attempting to alleviate stress by avoiding or ignoring a stressor and attending to emotional needs related to one's stress reaction

Personal Control

our sense of controlling our environment rather than feeling helpless

Learned Helplessness

the hopelessness and passive resignation an animal or human learns when unable to avoid repeated aversive events

External Locus of Control

the perception that chance or outside forces beyond your personal control determine your fate.

Internal Locus of Control

the perception that you control your own fate

Self-Control

the ability to control impulses and delay short-term gratification for greater long-term rewards

Observational Learning

learning by observing others; also called social learning

Modeling

the process of observing and imitating a specific behavior

Mirror Neurons

frontal lobe neurons that fire when performing certain actions or when observing another doing so. The brain's mirroring of another's action may enable imitation, language learning, and empathy.

Prosocial Behavior

socially desirable behavior that benefits others

Albert Bandura

pioneer in observational learning (AKA social learning), stated that people profit from the mistakes/successes of others; Studies: Bobo Dolls-adults demonstrated 'appropriate' play with dolls, children mimicked play

Ivan Pavlov

experimental neuroses & classical conditioning; associated food for dogs with sound of a bell

Robert Rescorla

used unconditioned stimulus (+or-) and a conditioned stimulus to announce the arrival of another unconditioned stimulus

B.F. Skinner

behaviorist who created techniques to manipulate the consequences of an organism's behavior in order to observe the effects of subsequent behavior; Studies: Skinner box (people learn from punishments and rewards)

Edward Thorndike

law of effect theory; cat inside box with meat outside; noted that cat escaped faster knowing that the meat would be there

Edward Tolman

behaviorism; learning occurs even without reinforcement; learning = result of basic stimulus-return pattern

John B. Watson

conditioning process; Little Albert Experiment = child conditioned to fear neutral stimulus; environment shapes development & father of behaviorism

John Garcia

discovered long delay aversion learning; food associated with negative reaction
