Abstract:听According to canonical models of decision making, trading speed versus accuracy is accomplished by adjusting the threshold for the amount of evidence to be accumulated before responding. Rich Heitz, in Jeffrey Schall's lab, carried out the first neurophysiological study of speed-accuracy tradeoff, sampling neural spiking in the frontal eye field, superior colliculus, and supplementary eye field of monkeys performing an inefficient visual search task with instructed speed-accuracy emphases. Professor Schall will survey the neural findings, which were more complex but no less comprehensible than the canonical models. A major implication of these results is that the proposition linking neural activity to evidence accumulation is more veiled than commonly appreciated.
