前颞叶在知觉组织中的作用：脑损伤病人的神经心理学研究

相邻性组织和相似性组织是两种极为重要的“知觉组织(perceptual organization)”．我们对前颞叶切除的患者CXY进行了相邻性组织与相似性组织的研究．利用由小图形组成的大图形来研究在相邻性组织与相似性组织中整体与局部之间的相互影响．研究中发现：在相邻性组织中，正常被试所体现的整体对局部的影响显著大于局部对整体的影响这一现象在CXY身上消失了，即CXY相邻性组织的自动加工出现了障碍；在相似性组织中，患者CXY的实验结果与正常被试没有任何差异．另外，在一致连通性(uniform connectedness, UC) 与相邻性组织及相似性组织之间的关系实验中，也发现CXY相邻性组织的自动加工出现了障碍．这些结果说明左前颞叶在相邻性组织、整体知觉以及对连通性的知觉中起到重要的作用．

The Role of The Anterior-Temporal Lobe in The Perceptual Organization: a Neuropsychological Study

Proximity and similarity organization are two extremely important kinds of perceptual organization. In this study, a patient with anterior-temporal lobe damage CXY took part in our proximity and similarity experiments. In this study, compound stimuli that a global figure made up of local figures were used to investigate the interference of global and local in the proximity and similarity perceptual organization. In the global-local experiment, we found that, normal subjects showed stronger global interference than local interference in the proximity perceptual organization. Such effect, however, disappeared in CXY, suggesting there was an obstacle in his automatic processing of the proximity organization; in similarity organization, there was no difference between CXY and normal subjects. In the uniform connectedness experiment, we also found the obstacle in CXY's automatic processing of the proximity organization. These results indicated that the anterior-temporal lobe plays an important role in proximity organization, global organization and uniform connectedness.
