Terms | Definitions |
|---|---|
learning | relatively permanent change in an organism's behavior due to experience |
associative learning | learning that certain events occur together. Events may be two stimuli (classical conditioning) or a response and its consequences (operant conditioning) |
classical conditioning | type of learning in which an organism comes to associate stimuli |
unconditioned response (UR) | clasical conditioning: unlearned, naturally occurring response to the unconditioned stimulus (US), such as salivation when food is in the mouth |
unconditioned stimulus | in classical conditioning, a stimulus that unconditionally- naturally and automatically- triggers a response |
conditioned response (CR) | classical conditioning, learned response to a previously neutral (but now conditioned) stimulus (CS) |
conditioned stimulus (CS) | in classical conditioning, an originally irrevelant stimulus that, after association with an unconditioned stimulus (US), comes to trigger a conditioned response |
acquisition | initial stage in classical conditioning; phase associating a neutral stimulus with an unconditioned stimulus; strengthening of a reinforced response in operant conditioning |
extinction | diminishing of a conditioned response |
spontaneous recovery | reappearance after a pause, of an extinguised conditioned response |
generalization | 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 distinguise between a conditioned stimulus and stimuli that do not signal an unconditioned stimulus |
operant conditioning | type of learning 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 |
operant behavior | behavior that operates on the environment, producing consequences |
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 | chamber also known as Skinner's box, containing a bar so an animal can manipulate to obtain food as a reinforcer and used in operant conditioning |
shaping | 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 positive stimuli such as food |
negative reinforcement | increasing behaviors by stopping or reducing negative stimuli, such as shock |
primary reinforcer | in 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 |
continuous reinforcement | reinforcing that desired response every time it occurs |
partial (intermittent) reinforcement | reinforcing a response only part of the time |
fixed-ratio schedule | in operant conditioning, a reinforcement schedule that reinforces a response only after a specifed number of responses |
variable-ration schedule | in operant conditioning, a reinforcement schedule that reinforces a response after an unpredictable number of responses |
variable-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 | 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 | desire to perform a behavior for its own sake |
extrinsic motivation | desire to perform a behavior to promised standards or threats of punishment |
observational learning | learning by observing others |
modeling | 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 |
prosocial behavior | positive, constructive, helpful behavior |
