Paying Attention through Eye Movements: A Computational Investigation of the Premotor Theory of Spatial Attention
Growing evidence indicates that planning eye movements and orienting visuospatial attention share overlapping brain mechanisms. A tight link between endogenous attention and eye movements is maintained by the premotor theory, in contrast to other accounts that postulate the existence of specific attention mechanisms that modulate the activity of information processing systems. The strong assump...
متن کاملControl of eye movements and spatial attention.
Several lines of evidence suggest that planning eye movements and directing visuospatial attention share overlapping brain mechanisms. This study tested whether spatial attention can be enhanced by altering oculomotor signals within the brain. Monkeys performed a spatial attention task while neurons within the frontal eye field, an oculomotor area within prefrontal cortex, were electrically sti...
متن کاملSpatial attention and latencies of saccadic eye movements
Recent theories of visual attention, such as the oculomotor readiness theory of Klein (1980) (Does oculomotor readiness mediate cognitive control of the visual attention. In: R. Nickerson, Attention and performance, Hillsdale: Erlbaum), the premotor theory of Rizzolati (1983) (Mechanisms of selective attention in mammals. In: J.P. Ewart, R.R. Capranica, D.J. Ingle, Advances in vertebrate Neuroe...
متن کاملSpatial allocation of attention during smooth pursuit eye movements
We used a dual-task paradigm to investigate the spatial allocation of attention during smooth pursuit. Subjects tracked one character in a translating string of characters (block letter 8's), and during maintained pursuit, one of the characters briefly changed to an E or 3. Based on the ability of subjects to correctly discriminate the probed character, we found that the primary focus of attent...
متن کاملPaying Attention to the Details of Attention
Attention selects behaviorally relevant stimuli for greater neural representation. In this issue of Neuron, Luo and Maunsell (2015) show that attention acts, in part, by boosting the signal-to-noise ratio (SNR) of sensory neurons.
