Summary
In order to jointly explain latent inhibition and occasion setting, Buhusi and Schmajuk (1996) combined the attentional and associative systems of the SLG neural network (Chapter 2) with the configuration mechanisms of the SD neural network (Chapter 11). As mentioned, the SLG model describes the multiple properties of latent inhibition (Chapter 5), overshadowing and blocking (Chapter 8) and extinction (Chapter 9). On the other hand, the SD/SLH model correctly describes negative and positive patterning, as well as most of the features of occasion setting (Chapter 12). Buhusi and Schmajuk (1996) demonstrated that the attentional–configural model describes a broad range of experimental results, including: (a) acquisition and extinction series, (b) overshadowing and blocking, (c) discrimination acquisition and reversal, (d) conditioned inhibition and inhibitory conditioning, (e) simultaneous feature-positive discrimination, (f) serial feature-positive discrimination (occasion setting), (g) negative patterning, (h) positive patterning, and (i) reduced responding when context is switched. In addition, the model describes (j) sensory preconditioning, (k) latent inhibition, (l) contextual effects on LI, and (m) place and maze learning. This chapter presents a simplified version of the attentional–configural model described Buhusi and Schmajuk (1996) to address the properties of extinction cues.
Attentional and configural mechanisms in extinction
Some experiments have studied the effect of extinction cues (ECs), i.e. temporally discrete cues preceding the presentation of the CS during extinction. During testing, the presence of ECs tends to decrease responding.
