Topic: Decision models

Decision models involving protracted temporal integration of sensory information are known to provide excellent fits to decision behaviour. However, despite the computational advantage in principle, several studies have suggested a limited role for extended integration in practice, variously finding that it is subjected to low bounds, applied over a short timeframe, or plausibly replaced by non-integration strategies such as extrema detection. Here, we probed the role of extended integration in a noiseless but difficult contrast comparison task with response choices made after viewing a long 1
