Some Other Conditioning Procedures of Interest Conditioned Inhibition Conditioned Facilitation Second-Order Conditioning Sensory Preconditioning Inflation Deflation
Conditioned Inhibition Definition: A CS signals the absence of an otherwise expected US Standard Method: Conditioned Inhibition Procedure CSA +CSB
Conditioned Inhibition Notation: A+, AB- A CS can opener (excites) B CS rattle (inhibits) USfood
Measurement Problem True Inhibition CR actively inhibited = no CR Lack of Excitation Lack of excitation = no CR
Retardation and Summation Tests Common Treatment Phase The Experimental Group receives inhibitory training with CSB. The Control Group receives no training with CSB.
Retardation Test Group Inhibition Control Treatment A+, ABA+, AC- Test B+ B+ Result cr CR
Conditioned Inhibition Why Does the Experimental Group Learn More Slowly? Excitation + Tendency to Salivate to CSB 0 Inhibition The Control Group starts at 0. Going from Trial 1 to Trial 5, the level of excitation increases.
Conditioned Inhibition Why Does the Experimental Group Learn More Slowly? Excitation + Tendency to Salivate to CSB 0 Inhibition The Experimental Group starts below 0. It takes extra trials to bring them up to 0, then more trials to raise the level of excitation.
Summation Test Group Inhibition Control Logic: Inhibition: Control: Treatment Excitor A+, ABT+ A+, ACT+ Test TBTB- T + B = 1 + -1 = 0 T+B=1+0=1 Result cr CR
Conditioned Facilitation Definition: CSA signals the US only in the presence of CSB B (A Notation: A-, BA+ US)
Nature of Conditioning Question: Does the CS evoke an “expectation” of the US (S-S) or does the CS directly elicit the CR (S-R) ? US CS S-R Theory S-S UR CR
Second-Order Conditioning Stage 1 A->US Stage 2 B->A Very Few Trials Test B->CR
Second-Order Conditioning The “sad” story of Billy and the Bulldog First-Order Dog->Bite Second-Order Elevator->Dog
S-S Account Problem: Underlying Fear of Dog->Bite Elevator->Dog So…Elevator->Dog->Bite S-S Therapy: Extinguish Dog Fear
S-R Account Problem: Elevator Evokes Fear Dog->Bite Elevator->Dog Fear So…Elevator-Fear S-R Therapy: Extinguish Elevator Fear
Other Procedures (S-S Only) 1. Sensory Preconditioning 2. Inflation 3. Deflation
Sensory Preconditioning Treatment B->A SPC A->US Result B->CR Very Few Trials S-R Theory B->no CR S-S Theory B->A->US
Inflation Treatment A->us S-R Theory A->Same cr Inflate US Result A->CR S-S Theory A-> Bigger CR
