ABSTRACT
This chapter describes the syllogistic task, the main approaches to syllogistic reasoning, and outlines the working memory model. The models approaches of Sternberg, Fisher, and Johnson-Laird specifically propose a role for working memory in syllogistic reasoning even when the premises are continuously available to the participants. The role of working memory in reasoning can be usefully investigated using the model and methods developed by Baddeley and colleagues. It consists of three main components: the phonological loop, the visuo spatial scratchpad, and the central executive. Secondary task methods have been the prime means for investigating the contribution of the working memory components to target tasks. Dual task methods were used to assess the role of working memory components. Spatial random generation rate was significantly slowed by dual tasking in the high group only. The experimental participants worked through the training booklet at their own pace and were then given the 20 item screening test used in experiment.
