Conditioned Inhibition Definition: A CS signals the absence of an otherwise expected US. Standard Method: Conditioned Inhibition Procedure CSA +CSB Notation: A+, AB-
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: A CS signals the presence of a US that would not otherwise occur. Standard Method: Conditioned Facilitation Procedure CSA +CSB “Here Boy” Notation: A-, AB+
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 Treatment A->US SOC B->A Very Few Trials Result B->CR
Second-Order Conditioning The “sad” story of Billy and the Bulldog Treatment Dog->Bite SOC Elevator->Dog Result Elevator Phobia .
S-R Theory E CR S-S Theory E D US CR
S-R Therapy Problem: Afraid in Presence of Elevator Cause D->US SOC E->D Result E->CR S-R Therapy: Extinguish Elevator Fear But……. Maybe it works because Billy no longer anticipates the dog in the elevator!!! [broken E->D]
S-S Therapy Problem: Underlying Fear of Dog Cause D->US SOC E->D Result E->D->US S-S Therapy: Extinguish Dog Fear S-S: Should cure both D and E fears S-R: Should cure D but not E fear
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
