Mechanisms of visual attention revealed by saccadic eye movements.
This paper summarizes recent data on the initiation of saccadic eye movement in relation to the mechanisms of visual attention. In particular, the occurrence of express saccades, defined by their extremely short reaction times, is discussed on the basis of the observation that these saccades do not occur when the subjects (man or monkey) are attending to either a fixation point or to any other ...
متن کاملVisual attention modifies spectral sensitivity of nystagmic eye movements
If we look out of the window of a travelling train our eyes move rapidly back and forth (saccadic movement). With no attention to individual objects, gaze velocity is low but nystagmic frequency is high (stare nystagmus). If we are interested in individual objects, the angular velocity of gaze is high and the nystagmic frequency low (look nystagmus) (Ter Braak, J.W.G. (1936). Untersuchungen ueb...
متن کاملThe role of visual attention in saccadic eye movements.
The relationship between saccadic eye movements and covert orienting or visual spatial attention was investigated in two experiments. In the first experiment, subjects were required to make a saccade to a specified location while also detecting a visual target presented just prior to the eye movement. Detection accuracy was highest when the location of the target coincided with the location of ...
متن کاملA Model of Eye Movements and Visual Attention
This paper introduces the EMMA model of eye movements and visual attention. EMMA provides a formal model of the temporal and spatial aspects of eye movements as they arise from shifts in visual attention. To implement the model, EMMA is integrated into the ACT-R/PM cognitive architecture (Anderson & Lebiere, 1998) and requires minimal modification of existing ACT-R/PM models. This paper details...
متن کاملVisual attention during the preparation of bimanual movements
We investigated the deployment of visual attention during the preparation of bimanually coordinated actions. In a dual-task paradigm participants had to execute bimanual pointing movements to different peripheral locations, and to identify target letters that had been briefly presented at various peripheral locations during the latency period before movement initialisation. The discrimination t...
