最近研究表明,瞬间注意的空间线索可以降低时间敏感度。我们使用9倍交错自适应算法(YAAP)研究了持续注意焦点的大小如何影响在95名健康受试者的视野中映射的双脉冲分辨率(DPR)阈值。偏心度在2.5°到20°之间时,外周DPR阈值升高。此外,中央DPR阈值在外围测量的越来越大的刺激显示器测量时以类似的速度增加。后一种效应表明,持续的注意力集中越大,时间分辨率就越低,而且不能仅用视网膜特征来解释。
Spatial cueing of transient attention has recently been shown to reduce temporal sensitivity. We investigated how the size of the sustained attentional focus influences double-pulse resolution (DPR) thresholds mapped across the visual field in a sample of 95 healthy subjects using a 9-fold interleaved adaptive algorithm (YAAP). Peripheral DPR thresholds increased for measurements between 2.5° and 20° eccentricity. Additionally, central DPR thresholds increased at a similar rate when measured with increasingly larger stimulus displays for peripheral measurements. This latter effect suggests that temporal resolution decreases with a larger sustained attention focus and cannot be explained by retinal characteristics only.
