UNIT 4 Flashcards
classical conditioning
a type of learning in which one learns to link two or more stimuli and anticipate events
behaviorism
the view that psycholgoy (1)should be an objective science that (2)studies behavior without references to mental processes
unconditioned response
in CC, the unlearned, naturally occuring response to the US
unconditioned stimulus
inCC, a stimulus that unconditionally - naturally and automatically - triggers a response
conditioned response
inCC, the learned response to a previously neutral (but now conditioned) stimulus
conditioned stimulus
inCC, an originally irrelevant stimulus that, after association with an US, comes to trigger a CR
acquisition
the intial stage in CC when one links a stimulus and an US so that the NS begins triggering the CR. In OC, the strengthening of a reinforced response
higher-order conditioning
a procedure in which the CS in one conditioning experience is paired with a new neural stimulus, creating a second (often weaker) CS
extinction
the diminishing of a CR; occurs in CC when an US does not follow a CS; occurs in OC when a response is no longer reinforced
spontaneous recovery
the reappearance, after a pause, of an extinguished CR
respondent behavior
behavior that occurs as an automatic response to some stimulus
operant conditioning
a type of learning in which behavior is strengthened if followed by a reinforcer or diminished if followed by a punisher
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
in OC research, a chamber (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
shaping
an OC procedure in which reinforcers guide behavior toward closer and closer approximations of the desired behavior
discriminative stimulus
in OC, a stimulus that elicits a response after association with reinforcement
reinforcer
in OC, any event that strengthens the behavior it follows
positive reinforcement
increasing behaviors by presenting positive stimuli, such as food. It is any stimulus, when presented after a response, strengthens the response
negative reinforcement
increasing behaviors by stopping or reducing negative stimuli, such as a shock. When removed after a response, strengthens the response
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 schedule
reinforcing the desired response every time it occurs
