Abstract

Watson and Turano (Vision Research 1995;35:325-336) described experimental research aimed at determining the motion stimulus that the visual system detects best. They reported conflicting results in the determination of the optimal spatial size and they interpreted them as an effect of probability summation. They also reported disagreement with earlier results of Watson et al. (Nature 1983;302:419-422). This study shows (i) that probability summation is not responsible for those results and (ii) that they can be explained as a consequence of the method that was used to search for the optimal stimulus.

摘要

沃森和图拉诺（《视觉研究》，1995年；35卷：325 - 336页）描述了旨在确定视觉系统最易检测到的运动刺激的实验研究。他们在确定最佳空间大小时报告了相互矛盾的结果，并将其解释为概率总和的效应。他们还报告了与沃森等人早期研究结果（《自然》，1983年；302卷：419 - 422页）的不一致。本研究表明：（i）概率总和并非这些结果的原因；（ii）这些结果可解释为用于寻找最佳刺激的方法所导致的结果。
