Cards

Term
stimulus (pl. stimuli)
Definition
any physical event, combination of events, or relation among events
Term
response
Definition
a unit of behavior; a discrete & usually reoccurring segment of behavior
Term
elicit
Definition
a call forth, draw out, or provoke (a reaction, for example)
Term
habituation
Definition
decline in tendency to respond to stimuli that have become familiar due to repeated exposure
Term
the course of habituation
Definition
large declines in responding first, progressively get smaller
Term
8 laws of short-term habituation
Definition
1. spontaneous recovery
2. repeated habituation --> more rapid habituation
3. rate of habituation faster for shorter ISI
4. rater of habituation faster for weaker stimuli
5. below-zero habituation
6. habituation is specific
7. dishabituation
8. habituation of dishabituation
Term
classical conditioning
Definition
learning that a previously neutral stimulus predicts the occurrence of an important stimulus
Term
Pavlov's dog
Definition
after repeatedly feeding his dog immediately after ringing a bell, the dog salivated in response to the sound of the bell alone; conditioned response to bell (CR)
Term
the "unconditioned stimulus" (US) for Pavlov's dog was the _____
Definition
food (because food normally/unconditionally evokes salivation)
Term
the "conditioned stimulus" (CS) for Pavlov's dog was the _____
Definition
bell (because the bell does not normally evoke salivation; the bell got paired with the food/the unconditioned stimulus)
Term
association
Definition
if 2 sensations, or stimuli, repeatedly occur together, the mental reactions to those stimuli become associated such that when the first sensation or stimulus is given, it triggers the memory of the associated stimulus
Term
Pavlov's original experiment is an example of _____ classical conditioning
Definition
excitatory
Term
What is meant by "excitatory" classical conditioning?
Definition
the CS is able to excite the CR into being
Term
From a procedural point of view, ______ occurs when the presentation of the CS is followed by a presentation of the US (i.e. CS --> US pairings)
Definition
conditioned excitation (or excitatory conditioning)
Term
Is contingency or contiguity crucial to conditioning?
Definition
contingency
Term
3 ways that way know that the CR arises from the pairing CS-US
Definition
1. repeated presentations of the CS alone (explicit unpairing) before pairing does not produce CR
2. repeated presentations of the CS alone after pairing extinguishes CR (extinction)
3. random presentations of the CS & US do not produce CR
Term
All animals, including humans, are born with an innate set of _____ - wired-in responses to specific environmental stimuli
Definition
reflexes
Term
reflex
Definition
a relationship between a specific environmental event (a stimulus "S") and a behavioral action (a response "R") that it evokes
Term
3 presentations of CS & US that do not support learning
Definition
1. backwards conditioning
2. simultaneous conditioning
3. explicitly & randomly unpaired
Term
2 advantages of the method of classical conditioning for the study of the neurobiology of learning & memory
Definition
1. the engram (memory site) is found at the convergence of the pathways carrying the CS & US information
2. the learned behavior (CR) is a unique output resulting from the proper pairing of the CS & US & can be measured precisely in terms of latency (to CS) and strength
Term
5 important characteristics of a behavioral model conditioned response system to investigate the neural substrates of learning & memory
Definition
1. the conditioned response (CR) should be quantifiably measureable in terms of latency & amplitude
2. the CR should be well characterized under a variety of stimulus conditions to determine changes in its rate of acquisition, frequency of occurrence, and/or amplitude
3. the CR should be associative in nature & clearly distinguishable from nonassociative forms of learning
4. the CR should emerge rapidly & should endure
5. the afferent & efferent pathways responsible for the expression of the CR should be known or at least amenable to analysis
