-
learning
a relatively permanent change in an organisms behavior due to experience
-
associative learning
learnign that certian events occur together. The events may be two stimuli (as in classical conditioning) or a response and its consequences (as in operant conditioning)
-
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
2.studies behavior without reference to mental processes
Most research psychologist today agree with 1 but not with 2
-
Unconditioned Response (UR)
in classical conditioning, the unlearned, naturally occurring response to the uncondtioned stimulus (US), such as salivation when food is int he 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 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
in classical conditioning, the inital stage, when one links a neutral stimulus and an unconditioned stimulus so that the neutral stimulus begiins triggering the conditioned response.
in operant conditioning, the threngthening of a reinforces response
-
higher-order conditioning
a procedure in ehich the conditioned stimulus in one conditioning experience is paired with a new neutral stimulus, creating a second (often wearker) condiioned stumulus.
example---an animal that has learned that a tone predicts food might then learn a light predicts the tone and begin responding to the light alone
-
extinction
the diminidhing 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 distingusih between a conditioned stimulus and stimuli that do not signal an unconditioned stimulus
-
respondent behavior
behavior that occurs as an automatic response to some stimulus
-
operant conditioning
a type of learning in which behavior is strenghtened if followed by a reinforcer or diminished if followed by a punisher
-
operant behavior
behavior that operates on the enviorment, producing consequences
-
law of effect
Thorndike's prinicple 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 (aka Skinners box) containing a bar or key that an animal can manipulate to obtain a food or water reinforcer; attached devices record the animals rate of bar pressing or key pecking
-
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 positive stimuli, such as food. A postive reinforcer is any stimulus that, when presented after a response, strengthens te response
-
negative reinforcement
- increasing behaviors by stopping or reducing negative stiluli, such as shock. A negative reinforcer is any stimulus that. when removed after a response, strenghtens the response
- (not a 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
-
continuous reinforcement
reinforceing the desired response evvery 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 reingorcement schedule that reinforces a response after an unpredictable number of responses
-
fixed-interval schedule
in operant conditioning, a reinforcement schedule that reinforces a response inly after a specified time as elapsed
-
variable-interval schedule
in operant conditioining, a reinforcement schedule that reinforces a response at unpredictable time intervals
-
cognitive map
a mental representation of the layout of one's enviroment, For example, after exploring a maze, rats act as if they have already learned a cognitive map of it
-
latent learning
learning that occurs but is not apparent untill there is an incentive to demonstrate it
-
intrinsic motivation
a desire to perform a behavior effectively for its own sake
-
extrinsic motivation
a desire to perform a behavior to recieve promised rewards or avoid threatened punishment
-
observational learning
learning by observing others
-
modeling
the process of observing and imitating a specific behavior
-
mirror neurons
frontal lobe neurons that fire when performing certian actions or when observing another doing so . The brains mirroring of anothers action may enable imitation and empathy.
-
prosical behavior
positive, constructive, helpful behavior. The opposite of antisocial behavior
