When do microsaccades follow spatial attention?
Following up on an exchange about the relation between microsaccades and spatial attention (Horowitz, Fencsik, Fine, Yurgenson, & Wolfe, 2007; Horowitz, Fine, Fencsik, Yurgenson, & Wolfe, 2007; Laubrock, Engbert, Rolfs, & Kliegl, 2007), we examine the effects of selection criteria and response modality. We show that for Posner cuing with saccadic responses, microsaccades go with attention in at...
متن کاملSpatial and temporal attention revealed by microsaccades
We compared the spatial and temporal allocation of attention as revealed by microsaccades. Observers viewed several concurrent "rapid serial visual presentation" (RSVP) streams in the periphery while maintaining fixation. They continually attended to, and discriminated targets in one particular, cued stream. Over and above this continuous allocation, spatial attention transients ("attention shi...
متن کاملMicrosaccades Are an Index of Covert Attention
Horowitz, Fine, Fencsik, Yurgenson, and Wolfe (2007, this issue) investigated the relation between microsaccade congruency (MC, the congruency between the direction of the microsaccade and the location of the target) and reaction time (RT) in a spatial cuing paradigm and concluded that ‘‘fixational eye movements are not an index of covert attention.’’ We show that microsaccade direction is a re...
متن کاملSpontaneous microsaccades reflect shifts in covert attention.
Microsaccade rate during fixation is modulated by the presentation of a visual stimulus. When the stimulus is an endogenous attention cue, the ensuing microsaccades tend to be directed toward the cue. This finding has been taken as evidence that microsaccades index the locus of spatial attention. But the vast majority of microsaccades that subjects make are not triggered by visual stimuli. Unde...
متن کاملWhen cross-modal spatial attention fails.
There is now convincing evidence that an involuntary shift of spatial attention to a stimulus in one modality can affect the processing of stimuli in other modalities, but inconsistent findings across different paradigms have led to controversy. Such inconsistencies have important implications for theories of cross-modal attention. The authors investigated why orienting attention to a visual ev...
