在视网膜敏锐度受控制的辨别任务中，研究了注意运动时间。在两种选择的强制选择延迟范式中，Ss区分目标。在实验1-3中，成本受距离的调节，尽管它的变化与敏锐度无关。在实验4和7中，在距离保持不变的情况下，穿越垂直和水平子午线以及穿越1和2子午线的成本是相等的。然而，穿越1条子午线所产生的成本低于移动到同一象限的意外位置所产生的成本，部分复制了Tassinari， Aglioti,Chelazzi，Marzi和Berlucchi（1987）的抑制后效。一种基于模拟运动（Tsal, 1983）和注意分布（Downing & Pinker, 1985; Hughes & Zimba, 1987; Tassinari et al., 1987）模型结合的解释被讨论。
Attentional movement time was investigated within and across hemifields in a discrimination task in which retinal acuity was controlled. Ss discriminated targets in a two-alternative, forced-choice latency paradigm. In Experiments 1-3, costs were mediated by distance, even though it was varied independently of acuity. In Experiments 4 and 7, with distance held constant, costs were equivalent for crossing the vertical and horizontal meridians and for crossing 1 and 2 meridians. However, crossing 1 meridian produced costs that were less than the costs for shifts to unexpected locations in the same quadrant, partially replicating the inhibitory aftereffect of Tassinari, Aglioti,Chelazzi,Marzi,and Berlucchi (1987). An explanation based on a combination of analog movement (Tsal, 1983) and attentional distribution (Downing & Pinker, 1985; Hughes & Zimba, 1987; Tassinari et al., 1987) models was discussed.
