We have devised a new free-vision task to index functional cerebral asymmetry for processing facial characteristics. Confirming its sensitivity to properties of lateralized hemispheric functions, left- and right-handers were clearly differentiated on this task with respect to several aspects of performance that conform with known differences between handedness groups in hemispheric asymmetry. Additionally, there were highly reliable and stable individual differences in perceptual asymmetries within handedness. Analyses of items in the task revealed that most of the differences between items in the asymmetries they elicited were random.
我们设计了一项新的自由视觉任务，以对处理面部特征的功能性脑不对称进行索引。为证实该任务对偏侧化半球功能特性的敏感性，左利手和右利手在这项任务中的几项表现上有明显差异，这些表现符合不同利手群体在半球不对称方面的已知差异。此外，在利手群体中，个体在感知不对称方面存在高度可靠且稳定的差异。对任务项目的分析表明，它们所引发的不对称中，项目之间的大多数差异是随机的。
