A behavioral economic theory of cue-induced attention- and task-switching with implications for neurodiversity

I present a stylized, analytical model of cue-induced attention- and task-switching — with a proposed neurobiological interpretation of the model’s features — to organize available empirical evidence on two widely-studied neurodevelopmental conditions: attention-deficit/hyperactivity disorder (ADHD) and autism spectrum disorder (ASD). Specifically, I use this framework to show how a systematic tendency to underestimate the opportunity costs of attention- and task-switching can give rise to several empirically-observed behavioral patterns in ADHD, and that the opposite tendency can give rise to empirically-observed behavioral patterns in ASD. While drawing on various economic concepts to formally express its predictions, the model offers new and inter-related conceptualizations of ADHD and ASD — as viewed through a behavioral microeconomic lens — that may be useful for understanding some subtypes and symptoms.
