Experimental manipulation of attention and executive functions
This project addresses the role that interactions of attentional networks, executive functions, and working memory processes play for inter-individual differences in general intelligence. Specifically, we are interested in the role of attentional inhibition processes in executive functions and working memory processes. For this, we use experimental manipulations that require attentional inhibition in tasks measuring executive functions and working memory processes. The analysis of experimental effects on amplitudes and latencies of event-related potential (ERP) components within these tasks provides us with information how inhibition processes influence the stream of neural information processing in tasks measuring executive functions and working memory processes. In addition, we use mathematical models for binary response tasks, such as the diffusion model, to get information on the different processes running while working on these tasks. Altogether, these results may provide a possibility to connect the often separately considered processes of attention, executive functions and working memory that are basic for individual differences in general intelligence.
