Smooth pursuit eye movements and perception share target selection, but only some central resources.
Smooth pursuit eye movements have been linked to perception by a common attentional mechanism. We investigated whether perceptual performance was traded for smooth pursuit performance. While tracking a red target cross, observers had to discriminate the orientation of a flashed peripheral grating. We manipulated the priority given to the two tasks. Pursuit gain changed according to observers' e...
متن کاملAttentional constraints on target selection for smooth pursuit eye movements
Saccadic eye movements are strongly influenced by shifts of attention to non-target objects. In contrast, we have shown previously that the initiation of smooth pursuit eye movements is relatively unaffected when attention is shifted to objects that are either stationary or move in the same direction as the pursuit target (Souto & Kerzel, 2008). Here, we asked how attention interacts with targe...
متن کاملAudition and vision share spatial attentional resources, yet attentional load does not disrupt audiovisual integration
Humans continuously receive and integrate information from several sensory modalities. However, attentional resources limit the amount of information that can be processed. It is not yet clear how attentional resources and multisensory processing are interrelated. Specifically, the following questions arise: (1) Are there distinct spatial attentional resources for each sensory modality? and (2)...
متن کاملAttentional pursuit is faster than attentional saccade.
How quickly can we shift the focus of visual attention? We compared the rates of two types of attentional shifts: attentional saccades (shifts between objects) and attentional pursuit (shifts along with a moving object). Instead of measuring the time required for a single shift, which confounds shift time with cue interpretation time, we measured the pace at which observers could make multiple ...
متن کاملSmooth pursuit eye movements and motion perception share motion signals in slow and fast motion mechanisms.
Pursuit eye movements correlate with perceived motion in both velocity and direction, even without retinal motion. Cortical cells in the monkey medial temporal region generate signals for initiating pursuit eye movements and respond to retinal motion for perception. However, recent studies suggest multiple motion processes, fast and slow, even for low-level motion. Here we investigated whether ...
