Research Topics

Assessing the relationship between mental speed and general intelligence on a neuro-cognitive level

In this project we investigate whether individual differences in mental speed give rise to individual differences in general intelligence. For this purpose, we expand the measurement of mental speed beyond the measurement of response times by using mathematical models of response times and event-related potentials (ERPs). We study if mental speed can be considered a property of the person that is stable over time. Moreover, we investigate the factor structure of mental speed, i.e. we analyze how strongly a general mental speed factor influences mental speed in a variety of paradigms. Finally, we analyze which components in the stream of information processing (e.g., the speed of encoding, the speed of memory access, the speed of decision making, the speed of motor responses) are most strongly related to general intelligence by decomposing the stream of information processing with diffusion models and ERPs.
