Topic: delayed match-to-comparison task

A major problem in identifying consistent neural markers underlying perceptual decision-making is that decisions are mostly inextricably linked to task-related confounds such as motor responses. By disentangling the choice content from choice direction and the physical response, we showed in prior studies that vibrotactile decision content is nevertheless most likely represented effector-specific (i.e. in brain areas associated to the required motor response). In the current study we used a visual adaptation of the delayed match-to-comparison task to test whether perceptual decisions would be
