Abstract:

Why are some people more intelligent than others? How do we adapt our behavior after making an error? And how can we reliably measure the cognitive processes underlying these behaviors? In this talk, I will introduce my research at the lab for Differential Psychology at Heidelberg University, which addresses these questions from a neurocognitive psychometrics perspective. By combining neurophysiological methods, computational models of cognition, and psychometric approaches, we aim to uncover the mechanisms underlying individual differences in cognitive performance and adaptive behavior. I will present recent findings on the neurocognitive basis of intelligence, the dynamics of post-error behavior in both laboratory and real-world settings, and advances in measuring cognitive processes. Together, these studies illustrate how integrating neuroscience, cognitive modeling, and psychometrics can provide a more precise understanding of human cognition and behavior.
