Title: Deconstructing a cognitive process: Fractionation and developmental change in task switching
Abstract: The talk will describe fractionating a higher-order cognitive process and studying change across the lifespan using a large Internet-based dataset (n=14,732). First I will describe using the Additive Factors Method, a process decomposition technique that aims to statistically fractionate a complex cognitive process into subprocesses. Second, the talk will discuss modelling fine-grained age-related change in performance. Segmented/piece-wise regression was used to model the lifespan trajectories in performance and identify the transition periods at which shifts occurred.
