Chapter 8: Learning (Psychology)

Learning

Learning

a relatively permanent change in an organism's behavior due to experience

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)

behaviorism

the view that psychology should be an objective science that studies behavior without reference to mental processes

classical conditioning

a type of learning in which an organism comes to associate stimuli. A neutral stimulus that signals an unconditioned stimulus (US) begins to produce a response that anticipates and prepares for the unconditioned stimulus. Also called Pavlovian or respondent 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 response (CR)

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

conditioned stimulus (CS)

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

acquisition

The initial stage in classical conditioning; the phase associating a neutral stimulus with an unconditioned stimulus so that the neutral stimulus comes to elicit a conditioned response. In operant conditioning, the strengthening of a reinforced response.

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

unjustifiable negative behavior toward a group or its members

operant conditioning

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

respondent behavior

behavior that occurs as an automatic response to some stimulus; Skinner's term for behavior learned through classical conditioning

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 behavior

behavior that operates on the environment, producing consequences

shaping

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

reinforcer

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

positive reinforcement

increasing behaviors by presenting postive stimuli, such as food; when presented after a response, it strengthens response

negative reinforcement

increasing behaviors by stopping or reducing negative stimuli, such as shock; it is any stimulus that, when removed after a response, strengthens the response

primary reinforcer

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

conditioned reinforcer (secondary reinforcer)

a stimulus that gains its reinforcing power through its association with a primary reinforcer

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 decreases the behavior that it follows

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

intrinsic motivation

A desire to perform a behavior for its own sake

extrinsic motivation

a desire to perform a behavior due to promised rewards or threats of punishment

observational learning

learning by observing others

modeling

The process of observing and imitating a specific behavior

mirror neurons

Frontal lobe neuron that fires when performing certain actions or when observing another doing so; may enable imitations, language learning, and empathy

prosocial behavior

positive, constructive, helpful behavior. the opposite of antisocial behavior

operant chamber

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, with attached devices to record the animal's rate of bar pressing or key pecking. Used in operant conditioning research.
