本研究采用反应时和在线眼动测量相结合的方法，考察了视觉呈现物体对的“相同”-“不同”判断的时程。对观看模式、观看时间和反应时间的分析表明，参与者参与了一个平行的自我终止的差异搜索。此外，在一个维度上不同的对象所获得的结果表明，处理时间可能取决于刺激维度的相对编码能力。结果审查在一个更广泛的框架，鉴于高阶过程。我们建议，过度的颜色，经常发现在对象描述，可能有一个“早期”的视觉，而不是“后期”的语言起源。在对检测材料的平行评估中，参与者对物体颜色的过度指定远远超过其大小。我们认为，颜色的参考过度规格在很大程度上是由于视觉歧视的机制。
We investigated the time course of conjunctive "same''-"different'' judgements for visually presented object pairs by means of combined reaction time and on-line eye movement measurements. The analyses of viewing patterns, viewing times, and reaction times showed that participants engaged in a parallel self-terminating search for differences. In addition, the results obtained for objects differing in only one dimension suggest that processing times may depend on the relative codability of the stimulus dimensions. The results are reviewed in a broader framework in view of higher-order processes. We propose that overspecifications of colour, often found in object descriptions, may have an "early'' visual rather than a "late'' linguistic origin. In a parallel assessment of the detection materials, participants overspecified the objects' colour substantially more often than their size. We argue that referential overspecifications of colour are largely attributable to mechanisms of visual discrimination.
