a relatively permanent change in an organism's behavior due to experience
associative learning
learning that certain events occur together.
classical conditioning
a type of learning in which one learns to link two or more stimuli and anticipate events (must be instinctual)
behaviorism
psychology: (1) should be an objective science that (2) studies behavior without reference to mental processes.
unconditioned response (UR)
the unlearned, naturally occurring reaction to US, such as salivation when food is in the mouth
unconditioned stimulus (US)
a stimulus that naturally and automatically triggers a reaction (like food)
conditioned response (CR)
the learned reaction to a previously neutral stimulus (CS)
conditioned stimulus (CS)
an originally irrelevant stimulus that, after association with an US, comes to trigger a conditioned reaction
acquisition
the "learned" behavior or response
extinction
the diminishing of a CR; when a response is no longer reinforced
spontaneous recovery
the reappearance, after a pause, of an extinguished CR
generalization
the tendency, once a response has been conditioned, for stimuli similar to the CS to elicit responses
discrimination
the learned ability to distinguish between a CS and stimuli that do not signal an US
learned helplessness
the hopelessness and passive resignation an animal or human learns when unable to avoid repeated aversive events
operant conditioning
a type of learning in which behavior is strengthened if followed by a reinforcer or diminished followed by a punisher
law of effect
Thorndike's principle that behaviors followed by favorable consequences become more likely, or where behaviors followed by unfavorable consequences become less likely
operant chamber
Skinner box containing a bar or key that an animal can manipulate to obtain food or water reinforce; attached devices record the animal's rate of bar pressing or key pecking
shaping
reinforcers guide behavior toward closer and closer approximations of the desired behavior
discriminative stimulus
a stimulus that elicits a response after association with reinforcement (in contrast to related stimuli not associated with reinforcement)
reinforcer
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 reinforce
an innately reinforcing stimulus, such as one that satisfies a biological need
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
a reinforcement schedule that reinforces a response only after a specified number of responses
variable-ratio schedule
a reinforcement schedule that reinforces a response after an unpredictable number of responses
fixed-interval schedule
a reinforcement schedule that reinforces a response only after a specified time has elapsed
variable-interval schedule
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. (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 LATER
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; INSIDE
extrinsic motivation
a desire to perform a behavior to receive promised rewards or avoid threatened punishment, OUTSIDE
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 actions may enable imitation and empath
little albert
subject in John Watson's experiment, proved classical conditioning principles, especially the generalization of fear
Albert Bandura
researcher famous for work in observational or social learning including the famous Bobo doll experiment
John Garcia
Researched taste aversion. Showed that when rats ate a novel substance before being nauseated by a drug or radiation, they developed a conditioned taste aversion for the substance.
