Potential outcomes (sensitization, no change, habituation)

Examples

Vary in stim. and R complexity

Startle, perceptual learning, infant looking time, imprinting, recognition of a conspecific, emotions, pain (analgesia & hyperalgesia)

Criteria

Importance of testing under common conditions

Inference

Direct: change in R magnitude

Ruling out sensory adaptation and motor fatigue

Stimulus generalization

Variation in outcome across response systems

Indirect: inferred through its impact on another process

Impact on acquisition of a Pavlovian CR

Latent inhibition (CS habituation)

Perceptual learning (CS sensitization)

US preexposure effect (US habituation)

US enhancement (US sensitization)

Impact on an acquired response

Weaking a CS-elicited response (extinction)

Impact on instrumental learning

Neophobia

Learned helplessness

Phenomena

Dishabituation & spontaneous recovery

Short & long-term

Intrinsic modificatios w/in the S-R pathway

Extrinsic modulation

Unconditioned

Acquired (covered in later sections)

An example of S-S (Pavlovian) learning

Discrimination (alt. the gen. gradient)

Learning about the configuration of elements
