Unit 6 Flashcards
learning
a relatively permanent change in an organism’s behavior due to experience
habituation
an organism’s decreasing response to a stimulus with repeated exposure to it
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)
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 that (2) studies behavior without reference to mental processes. Most research psychologists today agree with (1) but not with (2)
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 (CS)
conditioned stimulus (CS)
in classical conditioned, an originally neutral stimulus that, after association with an unconditioned stimulus (US), comes to trigger a conditioned response
acquisition
in classical conditioning, the initial stage, when one links a neutral stimulus and an unconditioned stimulus so that the neutral stimulus begins triggering the conditioned response. In operant conditioning, the strengthening of a reinforced response
extinction
the diminishing of a conditioned response; occurs in classical conditioning when a unconditioned stimulus (US) does not follow a conditioned stimulus (CS); occurs in operant condition 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 responses
discrimination
in classical conditioning, the learned ability to distinguish between a conditioned stimulus and stimuli that do not signal an unconditioned stimulus
learned helplessness
the hopelessness and passive resignation an animal or human learns when unable to avoid repeated aversive events
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 reinforce or diminished 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, that behaviors followed by unfavorable consequences become less likely
operant chamber
in operant conditioning research, a chamber (also known as a 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
an operant conditioning procedure in which reinforcers guide behavior toward closer and closer approximations of the desired behavior
reinforce
in operant conditioning, any event that strengthens the behavior it follows
positive reinforcement
increasing behaviors by adding a desirable stimuli, such as food.
negative reinforcement
increasing behaviors by stopping or reducing aversive stimuli, such as shock.
primary reinforcer
an innately reinforcing stimulus, such as one that satisfies a biological need (food, water, removal of pain)
conditioned reinforcer
a stimulus that gains its reinforcing power through its association with a primary reinforcer; also known as a secondary reinforcer
