Strategic Impatience in Go/NoGo versus Forced-Choice Decision-Making

This video was recorded at 26th Annual Conference on Neural Information Processing Systems (NIPS), Lake Tahoe 2012. Two-alternative forced choice (2AFC) and Go/NoGo (GNG) tasks are behavioral choice paradigms commonly used to study sensory and cognitive processing in choice behavior. While GNG is thought to isolate the sensory/decisional component by removing the need for response selection, a consistent bias towards the Go response (higher hits and false alarm rates) in the GNG task suggests possible fundamental differences in the sensory or cognitive processes engaged in the two tasks. Existing mechanistic models of these choice tasks, mostly variants of the drift-diffusion model (DDM; [1,2]) and the related leaky competing accumulator models [3,4] capture various aspects of behavior but...
