Temporally flexible feedback signal to foveal cortex for peripheral object recognition
Abstract
When subjects were asked to discriminate objects in the periphery, foveal visual noise presented at precise time windows following the peripheral object onset disrupted their performance. Further, this effect of foveal noise depends on task demand and stimulus features and primarily occurs for object tasks that involve spatial details. The time window, during which the noise is effective, can be shifted based on the amount of preprocessing of the peripheral objects, revealing the operation of temporally flexible feedback processing in the foveal cortex for peripheral object recognition.
