摘要

我们比较了两种大小的眼窝拥挤的 Landolt C 的识别能力:短暂(40 毫秒)、大、低对比度的 C 和视觉系统分辨率极限的高对比度(1 秒)测试。在不同系列的测试中,测试的Landolt C周围有两个沿水平方向对称分布的相同干扰物,或者只有一个干扰物。这些分散物是兰多尔特 C 或圆环。在分辨率极限时,两个系列的临界间距相似,并不取决于分散物的类型。这一结果支持了这样的假设:当测试物和分心物都属于同一最小感受野时,分辨极限的拥挤现象就会发生,而这一最小感受野正是目标识别的基础。对于大的刺激物,几乎在所有的间距下,相同形状的干扰物比环形干扰物造成的损害更大,而且识别错误是非随机的。只有在有一个分散注意力的兰多特 C 的情况下,临界间距才等于 0.5 测试直径:当加入一个分心物时,不自主的注意力会指向刺激物的重心,从而导致混淆同时存在于测试和分心物中的特征,从而导致非随机性错误。

Foveal crowding for large and small Landolt Cs: Similarity and Attention

We compare the recognition of foveal crowded Landolt Cs of two sizes: brief (40 ms), large, low-contrast Cs and high-contrast (1 sec) tests at the resolution limit of the visual system. In different series, the test Landolt C was surrounded by two identical distractors located symmetrically along the horizontal or by a single distractor. The distractors were Landolt Cs or rings. At the resolution limit, the critical spacing was similar in the two series and did not depend on the type of distractor. The result supports the hypothesis that crowding at the resolution limit occurs when both the test and the distractors fall into the same smallest receptive field responsible for the target recognition. For large stimuli, at almost all separations distractors of the same shape caused greater impairment than did rings, and recognition errors were non-random. The critical spacing was equal to 0.5 test diameters only in the presence of one distracting Landolt C. This result suggests that attention is involved: When one distractor is added, involuntary attention, which is directed to the centre of gravity of the stimulus, can lead to confusion of features that are present in both tests and distractors and thus to non-random errors.

期刊介绍: Vision Research is a journal devoted to the functional aspects of human, vertebrate and invertebrate vision and publishes experimental and observational studies, reviews, and theoretical and computational analyses. Vision Research also publishes clinical studies relevant to normal visual function and basic research relevant to visual dysfunction or its clinical investigation. Functional aspects of vision is interpreted broadly, ranging from molecular and cellular function to perception and behavior. Detailed descriptions are encouraged but enough introductory background should be included for non-specialists. Theoretical and computational papers should give a sense of order to the facts or point to new verifiable observations. Papers dealing with questions in the history of vision science should stress the development of ideas in the field.
