Unit 6 - Learning Flashcards
learning
the process of acquiring new and relatively enduring information or behaviors
habituation
an organism’s decreasing response to a stimulus with repeated exposure to it
associatice learning
learning that certain events occur together (events may be two stimuli or a response and its consequence)
stimulus
any event or situation that evokes a response
cognitive learning
the acquisition of mental information, whether by observing events, by watching others, or through language
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 and 2 - studies behavior without reference to mental processes
neutral stimulus
(NS) in classical conditioning, a stimulus that elicits no response before conditioning
unconditioned response
(UR) an unlearned, naturally occurring response
unconditioned stimulus
(US) a stimulus that naturally triggers a response
conditioned response
(CR) a learned response to a previously neutral but now conditioned stimulus
conditioned stimulus
(CS) an originally irrelevant stimulus that, after association with an unconditioned stimulus, comes to trigger a conditioned response
acquisition
the initial stage, when one links a neutral stimulus and an unconditioned stimulus so that the neutral stimulus begins triggering the conditioned response
higher-order conditioning
procedure in which the conditioned stimulus is paired with a new neutral stimulus, creating a second, often weaker, response
extinction
the diminishing of a conditioned response; occurs when an unconditioned stimulus does not follow a conditioned stimulus
spontaneous recovery
the reappearance, after a pause, of an extinguished conditioned response (only after extinction)
generalization
the tendency, once a response has been conditioned, for stimuli similar to the conditioned stimulus to elicit similar responses
discrimination
the learned ability to distinguish between a conditioned stimulus and stimuli that do not signal an unconditioned stimulus
operant conditioning
a type of learning in which behavior is strengthened if followed by a reinforcer or diminished if followed by a punisher
law of effect
thorndike’s principle that behaviors followed by favorable consequences become more likely..etc
operant chamber/skinner box
a chamber 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
