Description

This paper describes the use of a Delayed Matching-to-sample procedure to examine remembering among individuals with Down syndrome of an age where neurodegeneration characteristic of dementia of the Alzheimer’s type is typically present. In Experiment 1, performance on computer-based match-to-sample tasks, measured by percent correct and discriminability (log d), was evaluated. Discriminability data was also fit to a logarithmic function to allow for evaluation of the form of the resulting forgetting function. Results suggested that the performance of this population is consistent with other populations represented in the literature in that percent correct declined as a function of increasing delay, and that the forgetting function showed a rapid initial decline with a slower rate of forgetting as the delay interval increased. In Experiment 2, performance of a mediating response during delay intervals was manipulated. Manipulation included the production and disruption of the mediating response. Results support the view that mediating behavior may function as precurrent behavior in that performance of a sample specific mediating response functions to increase the likelihood that the current operant (comparison selection) will fall within the required performance criteria for reinforcement. Results are discussed in terms of implications related to a behavioral interpretation of remembering behavior and in terms of treatment implications for conditions with significant degradation of remembering as a defining feature.
