Patients with left neglect were tested with "chimeric" figures composed of the right and left halves of two different objects. The connectivity relation was modulated between the two half figures. For some displays, the two chimeric halves were separated by a small gap, while in others, the separate halves were connected by a line segment. In line with previous reports, performance on reporting the left half improved when the chimera were separated; but when a line connected the two separated halves the advantage was lost. If the connecting line was broken, the performance was again enhanced. The results suggest an important role for connectedness in the representation of perceptual objects and in the distribution of attention in neglect.
左侧忽略症患者接受了“嵌合体”图形的测试，这些图形由两个不同物体的左右两半组成。两个半图形之间的连接关系被调制。对于一些显示，两个嵌合的半部分由一个小间隙隔开，而在其他情况下，分开的两半由线段连接。与之前的报告一致，当嵌合体分开时，报告左半部分的表现得到改善；但是当连接两个分开的半部分的线时，优势就消失了。如果连接线断开，表现再次增强。结果表明，连接性在知觉物体的表示和忽略中的注意力分配中起着重要作用。
