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
reinforcement
any event that strengthens the behavior it follows
shaping
reinforcers guide behavior toward closer and closer approximations of the desired behavior
discriminative stimulus
stimulus that elicits a response after association with reinforcement
