简单的神经观察，即视觉神经元的感受野在空间上被扩展，这是心理物理现象的核心，与有时对空间选择的需求有关。本文讨论了它在与选择性注意有关的三个异常中的作用，当在Eriksen侧翼任务中必须在时间压力下做出决定时，分心刺激显然有不适当的影响，与注意负荷有关的现象，即当对选择性注意的需求较小而不是较大时，目标远端的分心因子发挥更大的作用，以及在有侧翼存在的情况下，周围辨别能力的崩溃在某些情况下相对于相对注意可能是不对称的接近目标和侧翼的中心凹我们展示了面对空间混乱的输入，这些看似异常的现象是如何通过标准的贝叶斯推理产生的(C)2010爱思唯尔有限公司保留所有权利
The simple neural observation that the receptive fields of visual neurons are spatially extended lies at the heart of accounts of psychophysical phenomena to do with a sometimes unrequited need for spatial selection In this paper we consider its role in three anomalies associated with selective attention the apparently undue Influence of distractor stimuli when decisions in the Eriksen flanker task have to be made under time pressure the phenomenon associated with attentional load that distractors distal to a target exert more effect when the demands on selective attention are smaller rather than larger and the observation that crowding a breakdown in peripheral discriminability in the presence of flankers can under some circumstances be asymmetrical with respect to the relative proximity to the fovea of target and flanker We show how these seeming anomalies can arise from normative Bayesian Inference in the face of spatially confounded input (C) 2010 Elsevier Ltd All rights reserved
