Unconditioned stimulus (US
a stimulus that naturally evokes some response (f.e. Food since is evoked a natural response, such as salivation)
Unconditioned response (UR)
(their relationship does not depend on learning) they both occur unconditionally without prior training – the naturally occurring response to an unconditioned stimulus
Appetitive conditioning
the name of the conditioning when the unconditioned stimulus is a positive event (such as food delivery for Pavlov’s dog or ice cream for Moira)
- In general, appetitive conditioning consists of learning to predict something that satisfies a desire or appetite
Aversive conditioning
Conditioning in which the US is a negative event (such as a shock or an airpuff to the eye)
Eyeblink conditioning
A classical conditioning procedure in which the Unconditioned Stimulus is an airpuff to the eye and the conditioned and unconditioned responses are eye blinks – perhaps the most thoroughly studied form of motor reflex
Tolerance
A decrease in reaction to a drug so that larger doses are required to achieve the same effect
Homeostasis
the tendency of the body (including the brain) to gravitate toward a state of equilibrium or balance
Extinction
the process of reducing a learned response to a stimulus by ceasing to pair that stimulus with a reward or punishment
Delay
(less successful) - f.e. Not bringing the food out straight away
Compound conditioning
The simultaneous conditioning of two cues, usually presented at the same time
Overshadowing
occurs when a more salient cue within a compound acquires far more of the share of attention and learning than the less salient cue – A effect seen in compound conditioning when a more salient cue within a compound acquires more association strength, and is thus more strongly conditioned, than does the less salient cue
Blocking
a two-phase training paradigm in which prior training to one cue (CS1 → US) blocks later learning of a second cue when the two are paired together in the second phase of the training (CS1 + CS2 → US)
Prediction error (Rescorla-Wagner Model of Conditioning)
the difference between what was predicted and what actually occurred
Error-correction learning
a mathematical specification of the conditions for learning that holds that the degree to which an outcome is surprising modulates the amount of learning that takes place
Three key situations to consider in interpreting a prediction error
Rescorla–Wagner theory
this theory expects that the CS US association should increase proportional to the degree that the US is surprising; that is, the larger the error, the greater the learning
Associative weight
in the Rescorla-Wagner model of conditioning, a value representing the strength of association between a conditioned stimulus (CS) and an unconditioned stimulus (US)
Latent inhibition
A conditioning paradigm in which prior exposure to a CS retards later learning of the CS–US association during acquisition training – impaired learning following cue pre-exposure
US modulation theory
(this theory is correct) the Rescorla–Wagner model is often called a US modulation theory of learning because it proposes that the manner in which the US is processed determines what stimuli become associated with that US – measures strength of association to the stimulus
CS modulation theories
(this theory is correct) Any of the theories of conditioning holding that the stimulus that enters into an association is determined by a change in how the CS is processed
core idea of Mackintosh theory
that a previously conditioned stimulus derives its salience from its past success as a predictor of important events (Mackintosh, 1975), and this happens at the expense of other co-occurring cues that don’t get access to your limited pool of attention
Cerebellum
only responsible for the conditioned response (because the unconditioned response is reflexiv) – still processes the unconditioned stimulus
Purkinje cells
a type of large, drop shaped, and densely branching neuron in the cerebellar cortex
Interpositus
one of the cerebellar deep nuclei
