Conditioning Process

Living beings learn to associate known stimuli that exhibit specific temporal correlations. This kind of learning is called associative learning, and the process by which animals change their responses according to the schedule of arriving stimuli is called “classical conditioning”. In this paper, a conditionable neural network which exhibits features like forward conditioning, dependency on the interstimulus interval, and absence of backward and reverse conditioning is presented. An asymmetric neural network was used and its ability to retrieve a sequence of embedded patterns using a single recalling input was exploited. The main assumption was that synapses that respond with different time constants coexist in the system. These synapses induce transitions between different embedded patterns. The appearance of a correct transition when only the first stimulus is applied, is interpreted as a realization of the conditioning process. The model also allows the analytical description of the conditioning process in terms of internal and external or researcher-controlled variables.

Classical Aversive Conditioning

Classical aversive conditioning of heart rate in rats was studied using a 2 × 6 factorial design involving comparisons of trace and delayed conditioning procedures and six CS-US intervals (.0, .1, .3, .5, 1.0, and 6.0 sec.). Positive evidence of decelerative HR CRs was obtained at the .5, 1.0 and 6.0 ISIs, with maximum conditioning occurring at the 6.0 value. The results supported a modified version of the temporal gradient of reinforcement theory of classical conditioning. Problems relating to the separation of true CRs from nonassociative reactions to the CS were also discussed.
