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.

Learning Factors

Factors responsible for the success of covert sensitization were investigated with regard to effectiveness in initiating an aversion toward selected foods. 5 volunteers first were given forward-conditioning, then backward-conditioning trials using Cautela's covert sensitization procedures, and 5 Ss were given the opposite sequence. Conditions were then reversed allowing each S to serve as his own control. Significant reductions were found for all Ss in the intake of selected foods but no differential effect was found for the two conditioning procedures. This study supported the efficacy of using the rehearsal of an aversive scene to reduce food intake but suggests that motivational rather than learning factors may account for the results.

Flavour Preference

Changes in palatability of tastes and flavours as a result of flavour preference conditioning were examined. In Experiment 1, when tastes were paired with glucose in a reverse-order differential conditioning paradigm, rats acquired conditioned preferences for CS + and displayed more hedonic responses to CS + than to CS − in a postconditioning taste reactivity test. In Experiment 2, rats that received oral infusions of flavours as CSs during a reverse-order conditioning procedure expressed both palatability shifts and conditioned preferences for CS +. Rats that received a forward conditioning procedure acquired a preference for CS +, but the palatability of CS + was unchanged. In Experiment 3, hungry rats drank mixtures of a flavour CS and a calorific or sweet tasting reinforcer in a long-exposure conditioning paradigm. When tested hungry, rats preferred CS + whether they had acquired flavour-calorie or flavour-taste associations. However, CS + became more palatable only for rats that acquired flavour-calorie associations. These results suggest that acquisition of flavour preferences, as measured by 2-bottle tests, may not always be accompanied by enhanced palatability.

Control Procedures

Classical salivary conditioning was demonstrated in a classroom setting with the use of experimental control procedures to ensure an actual CR was being displayed and not pseudoconditioning. The significant increase in salivation in the forward conditioning group compared to that of the backward-paired group indicates this method can be used to condition salivation classically in the classroom.
