Spatial attention improves performance in spatial resolution tasks

摘要: This study used peripheral precueing to explore the effect of covert transient attention on performance in spatial resolution tasks. Experiments 1 (Landolt-square) and 2 ('broken-line') measured gap Experiment 3 vernier resolution. In all three tasks target was presented alone a large number possible locations, ranging from 1.5-6 degrees eccentricity vertical or horizontal axes. The precue indicated location but did not convey information regarding correct response. Performance decreased as size offset increased. Precueing improved terms RT accuracy tasks; cued trials These findings support idea that improvement at attended locations results, some extent, an enhanced location, just distractor exclusion, diminished uncertainty, decisional factors.
