Saccade preparation inhibits reorienting to recently attended locations.
We measured manual reaction time in normal human subjects to confirm that an eccentric visual signal has a biphasic effect on covert attention and eye movements. First, it summons attention and biases a saccade toward the signal; a subsequent inhibition of return then slows responses to signals at that location. A temporal hemifield dominance for inhibition of return was shown; this finding con...
متن کاملRecently attended masks are less effective.
Much work has been done to investigate participants' ability to detect repeated targets, but the presentstudy examined the influence of recently attended stimuli on target masking. Participants performed a target identification task in which the item that masked the target was either a recently attended item or a novel item. When it was identical to a previously attended stimulus, the mask was ...
متن کاملSaccade Preparation Reshapes Sensory Tuning
Human observers make large rapid eye movements-saccades-to bring behaviorally relevant information into the fovea, where spatial resolution is high. In some visual tasks [1-4], performance at the location of a saccade target improves before the eyes move. Although these findings provide evidence that extra-retinal signals evoked by saccades can enhance visual perception, it remains unknown whet...
متن کاملRepresentation of Attended Versus Remembered Locations in Prefrontal Cortex
A great deal of research on the prefrontal cortex (PF), especially in nonhuman primates, has focused on the theory that it functions predominantly in the maintenance of short-term memories, and neurophysiologists have often interpreted PF's delay-period activity in the context of this theory. Neuroimaging results, however, suggest that PF's function extends beyond the maintenance of memories to...
متن کاملSuperior Colliculus Responses to Attended, Unattended, and Remembered Saccade Targets during Smooth Pursuit Eye Movements
In realistic environments, keeping track of multiple visual targets during eye movements likely involves an interaction between vision, top-down spatial attention, memory, and self-motion information. Recently we found that the superior colliculus (SC) visual memory response is attention-sensitive and continuously updated relative to gaze direction. In that study, animals were trained to rememb...
