Working Memory and Cognitive Reasoning (WS 2019/20)

Organizer: Marco Ragni
Assistants: Hannah Dames, Nicolas Riesterer

Objective

The ability to reason logically is an important cognitive skill we use to draw inferences from information with which we are presented. Sometimes, drawing such a conclusion is effortful and requires many cognitive resources. But how do we hold given information temporarily available in order to manipulate and reason about given information? The system assumed to reflect our ability to maintain and manipulate information is called working memory: a core feature of our cognition.

The goal of this seminar is to examine the working memory - reasoning relationship by investigating whether individual differences in working memory predict individual differences in reasoning tasks. If working memory is the source of the computational limitation in the ability to reason when complex mental representations are required, then individuals with greater working memory capacity should show a better reasoning performance. Possibly, however, differences in working memory capacity lead to different reasoning strategies and thus, different response patterns.

To investigate this relationship, the seminar will apply machine learning methods and state-of-the-art cognitive models of reasoning using human generated data (working memory and reasoning tasks).
