Unbeknownst to most students of psychology, Pavlov’s first experiment was to ring a bell and cause his dog to attack Freud’s cat.

Operant Conditioning
Appetitive stimulus Organism wants to achieve or receive
Aversive stimulus Organism wants to avoid or escape from
Positive ReinforcementAdding consequence increases likelihood of a behavior
Negative ReinforcementRemoving consequence increases likelihood of a
behavior
PunishmentAdding consequence decreases likelihood of a behavior

C. Cognitive factors in Classical Conditioning
Unit VI. Learning17
The organism extracts information from the environment
classical conditioning involves more than the appearance of robot-like reflexive responses
organisms acquire conditioned responses when one event reliably predicts, or signals, the appearance of another
Example:Failure of redundant stimulus to become a CS
![Page 18: College Board - “Acorn Book” Course Description 7-9% Unit VI. Learning 1 VI. Learning.](https://reader035.fdocuments.in/reader035/viewer/2022062309/56649ea95503460f94bacf58/html5/thumbnails/18.jpg)
What determines whether and how a conditioned response is learned?
TimingForward conditioning (NS then UCS)Backward conditioning (UCS then NS)Interval between NS and UCS
PredictabilityAlways / Sometimes
Signal StrengthWeak shock / intense shock
![Page 19: College Board - “Acorn Book” Course Description 7-9% Unit VI. Learning 1 VI. Learning.](https://reader035.fdocuments.in/reader035/viewer/2022062309/56649ea95503460f94bacf58/html5/thumbnails/19.jpg)
AttentionWhen several stimuli are present, the one
the organism is paying attention to is more likely to become the CS
Biopreparednesscertain signals or events are especially likely
to form associations with other events“biologically prepared” or “genetically tuned”
to develop certain conditioned associations.Second-Order Conditioning
Fear of doctor associated with pain of shot but also white coat he’s wearing
![Page 20: College Board - “Acorn Book” Course Description 7-9% Unit VI. Learning 1 VI. Learning.](https://reader035.fdocuments.in/reader035/viewer/2022062309/56649ea95503460f94bacf58/html5/thumbnails/20.jpg)
Predictive value of CS – Rescorla
Assessment of the reliability of the stimulus to be a predictor
Cognitive interpretation of whether a stimulus is predictive rather than simple pairing of UCS - NS

Punishment vs. ReinforcementLarzelere
Spanked children have an increased risk of aggression , depression, and low self-esteem.
Reinforcement = increased behaviorPunishment = decreased behavior
Punishment doesn’t guide one towards a desired behavior rather it teaches one how to avoid getting caught.
