After scrolling Twitter, it will take you a while to get back into “work mode”. Why is this the case? Our new work (out now in Psych Review), led by Ivan Grahek and Xiamin Leng, explores the costs of adjusting cognitive control to meet different goals: psycnet.apa.org/record/2026-... 🧵 A thread:

We also discuss how a tradeoff between stability and flexibility in terms of control can lead to joint increases in behavioral measures of stability and flexibility. This has big implications for how we interpret stability and flexibility at the level of behavior vs underlying mechanisms of control.

Our key findings: - Optimal tradeoffs depend on task demands - Participants behave in line with normative predictions - Adjustments of control are tracked by pupil size and posterior alpha power

New preprint out! What is the optimal balance between cognitive stability (maximizing performance, minimizing distraction) and flexibility (switching between tasks)? We present a normative model that jointly optimizes stability vs flexibility and response speed vs accuracy during task switching.
