learning (modules 26-30) Flashcards
learning
the process of acquiring through experience new and relatively enduring information or behaviors
habituation
decreasing responsiveness with repeated exposure to a stimulus
associative learning
learning that certain events occur together
-two stimuli (classical conditioning)
-response and consequence (operant conditioning)
stimulus
any event or situation that evokes a response
respondent behavior
behavior that occurs as an automatic response to some stimulus
operant behavior
behavior that operates on the environment producing consequences
cognitive learning
the acquisition of mental information, whether by observing events, by watching others, or through language
classical conditioning
-type of learning where we link two or more stimuli
-the first stimulus comes to elicit behavior in anticipation of the second stimulus
ivan pavlov
-father of classical conditioning
-famous dog experiment where he conditioned dog to salivate at sound of a bell
john b watson
-little albert experiment
-idea that human emotions and behaviors are mainly a bundle of conditioned responses though biologically influenced
behaviorism
-the view that psychology should be an objective science that studies behavior without reference to mental processes
neutral stimuli (NS)
the stimulus that elicits no response before conditioning
unconditioned response (UCR)
an unlearned, naturally occurring response to and unconditioned stimulus
unconditioned stimulus (UCS)
a stimulus that naturally and automatically triggers and unconditioned response
conditioned response (CR)
a learned response to a previously neutral stimulus
conditioned stimulus (CS)
an originally neutral stimulus that after association with an unconditioned stimulus comes to trigger an conditioned response
acquisition
the initial stage when one links a NS with an UCS so that the neutral stimulus begins triggering the CS
classical conditioning is biologically adaptive because…
it helps humans and animals prepare for good or bad events
higher-order conditioning/second-order conditioning
-a procedure in which the CS is paired with a new US creating a second, weaker, CS
-example animal learns bell predicts food and light predicts bell so they associate light with food and salivate at light
extinction
the diminishing of a conditioned response
- when UCS doesn’t follow a CS
- when a response is no longer reinforced
spontaneous recovery
the reappearance of an extinguished conditioned response
generalization
the tendency once a response has been conditioned for stimuli similar to the CS to elicit similar responses
discrimination
learned ability to distinguish between a CS and similar stimuli that do not signal a UCS
applications of pavlov’s principles
drug cravings
food cravings
immune responses
operant conditioning
a type of learning in which a behavior becomes more likely to recur if followed by a reinforcer or less likely to recur if followed by a punishment
BF Skinner
-father of operant conditioning
-skinner box
Law of effect
-Edward Thorndike’s idea
-principle that behaviors followed by favorable consequences become more likely and behaviors followed by unfavorable consequences’ become less likely
operant chamber
-a chamber containing a bar/key that an animal can manipulate to obtain a reinforcers
-devices attached record the rate of animals bar pressing/key pecking
reinforcement
any event that strengthens the behavior it follows
