AP Psych: Mod 26-30

Meyers Unit 6

TermDefinition
learning the process of acquiring new and relatively enduring information or behaviors.
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.
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 any event or situation that evokes a response.
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).
neutral stimulus (NS) in classical conditioning, a stimulus that elicits no response before conditioning.
unconditioned response (UR) in classical conditioning, an un-learned, naturally occurring response (such as salivation) to an unconditioned stimulus (US) (such as food in the mouth).
unconditioned stimulus (US) in classical conditioning, a stimulus that unconditionally—naturally and automatically—triggers a response (UR).
conditioned response (CR) in classical conditioning, a learned response to a previously neutral (but now conditioned) stimulus (CS).
conditioned stimulus (CS) in classical conditioning, an originally irrelevant stimulus that, after association with an unconditioned stimulus (US), comes to trigger a conditioned response (CR).
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. (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.
extinction suppresses... but does not eliminate the 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.
What is the basic form of learning? classical conditioning
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 reinforcers. 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. 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.
continuous reinforcement reinforcing the desired response every time it occurs.
partial (intermittent) reinforcement 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 tends to decrease the behavior that it follows.
positive punishment weakens behavior by adding something negative to the environment.
negative punishment weakens behavior by removing something pleasant from the environment.
biofeedback a system for electronically recording, amplifying, and feeding back information regarding a subtle physiological state, such as blood pressure or muscle tension.
respondent behavior behavior that occurs as an automatic response to some stimulus.
operant behavior behavior that operates on the environment, producing consequences.
John Garcia his rat's avoided drinking from the water bottles that in radiation chambers. Rats linked the bad tasting water to the radiation that was making them sick.
taste aversion getting ill from food poisoning or a certain type of food, you will be less likely to eat that food again because of this association.
biological constraints predispose organisms to... learn associations that are naturally adaptive.
instinctive drift occurred as animals revert to biological predisposed patterns.
cognitive map a mental representation of the layout of one's environment. For example, after exploring a maze, rats act as if they have learned a cognitive map of it.
latent learning learning that occurs but is not apparent until there is an incentive to demonstrate it.
insight a sudden realization of a problem's solution; contrasts with strategy-based solutions.
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.
over justification people see their actions as externally controlled rather than internally appealing.
coping alleviating stress using emotional, cognitive, or behavioral methods.
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.
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 our personal control determine our fate.
internal locus of control the perception that chance or outside forces beyond our personal control determine our 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.)
mirror neurons frontal lobe neurons that some scientists believe fire when performing certain actions or when observing another doing so. The brain's mirroring of another's action may enable imitation and empathy.
modeling the process of observing and imitating a specific behavior.
prosocial behavior positive, constructive, helpful behavior. The opposite of antisocial behavior.
Albert Bandura Bobo Doll experiment.
over imitate excess/over the top imitation of actions not necessary to survival.
theory of mind children's brains enable their empathy and ability to infer another's mental state (contagious emotions).
When are model's most effective? when their actions and words are constant.
violence viewing effect the extent to which our aggressive behaviors stem from observation of TV, could be "justified" harm but its still harm (more influential if the violence is done by someone attractive).
How are pain and empathy connected? they show up in some of the same parts of the brain, but actual pain is in the somatosensory cortex.
vicarious reinforcement frequency of observing behaviors increases as a result of observing others rewarded for the same behavior.
vicarious punishment decrease in the frequency of certain behaviors or as a result of seeing others punished for that same behavior.
