Periodic Reporting for period 1 - VISSATO (Visual Search and Cognitive Control of the Speed-Accuracy Trade-off)
Período documentado: 2018-09-01 hasta 2020-08-31
The main results of our research are that (1) the search for motion stimuli violates common characteristics of visual search more generally; (2) the control of SAT during visual search can be explained by the modulation of brain dynamics by two classes of signals, mediated by upper-layer and lower-layer cortical projections respectively; (3) these signals are well characterized by spontaneous, structured neural activity, resulting from unstable dynamics prior to stimulus onset on visual tasks; (4) the characteristics of these signals differ between individuals in ways that correspond to quantifiable strategies toward visual search under speed or accuracy emphasis; and (5) such strategies have behavioural manifestations that differentiate and explain participants' performance on related cognitive tasks.
