Chapter 6: Learning Flashcards
Unconditioned Stimulus
a stimulus that evokes an unconditioned response without previous conditioning
Classical Conditioning
type of learning where stimuli acquires the ability to evoke a response
Unconditioned Response
unlearned reaction to an unconditioned stimulus without previous conditioning
conditioned response
previously neutral stimulus that, through conditioning, can trigger responses
Conditioned response
learned reaction to a conditioned stimulus because of previous conditioning
trial
presentation of stimulus or pair of stimulus
Acquisition
initial stages of learning, need stimulus contiguity (occurs at the same time and place), Intense, unusual stimuli have a higher chance of being a conditioned stimulus
Extinction
weakening of conditioned response, caused by the presentation of a conditioned stimulus without the unconditioned stimulus
Spontaneous Recovery
the reappearance of an extinguished response after a period of no exposure to a conditioned stimulus, the response is weaker when it returns,
renewal effect
if the response is extinguished in a different environment than it was acquired, the extinguished response will reappear in the original environment where its acquisition happened
stimulus generalization
occurs when an organism has learned a response to a specific stimulus and responds in the same way to a new similar stimulus. The more similar the stimuli the greater the generalization.
stimulus discrimination
occurs when an organism that learned a response does not respond the same way to a new similar stimulus. Organisms will learn to discriminate an original stimulus from a similar stimulus with enough exposure to both. Developed from pairing a conditioned stimulus and unconditioned stimulus, not an unconditioned stimulus with an unconditioned stimulus.
higher-order conditioning
where a conditioned stimulus can function as if it were an unconditioned stimulus
preparedness
a species-specific predisposition to be conditioned in certain ways and not others. preparedness results in phobias since they posed genuine threats to our ancestors.
evolved module for fear learning
(1) preferentially activated by stimuli related to survival threats in evolutionary history,
(2) automatically activated by these stimuli,
(3) relatively resistant to conscious efforts to suppress the resulting fears, and
(4) dependent on neural circuitry running through the amygdala.
Operant Conditioning
form of learning where a response is controlled by consequences, focuses on voluntary responses
