Abstract
The latency of visually guided saccades executed after acueing condition was adopted as amoreeco logical index to explore how spatia lattention , usually assessed by manual responses, operates in the visual field . Subjects executed saccades a imed towards one of 4 possible position s,equally distributed a round a central fix action cross. Before the on set of the saccadic target, a visual cuew as briefly presented at th e sam eorata different spatial location . The visual cuew as non -predictive of the target position . Two experimental sessions wer e carried out, differin g for the on set a synchrony between cue and target. A time-dependent coupling between the task -irrelevant location of th e cue and the direction of a follow in g over t shift of attention emerged . Clinical applications of the adopted experimental setting to neurological and psychiatric patients with motor impairments are discussed.
