人类的触觉偏侧效应是否可以归因于一个解剖学的路径传输模型或一些半球的机制参与的感知和/或调解活动在对侧hemispatial领域进行了确定。半球空间与视觉半视野不同，而是指身体中线左侧或右侧的外部空间。为了区分这两个假设，24个正常的dextra进行了触觉线平分任务，使用左手或右手在3个空间条件：在中线，在左半空间和右半空间。两个半球-半空间机制和半球-手的连接都有助于偏侧化效应。观察到假肾功能衰竭现象。
Whether human tactile laterality effects can be attributed to an anatomical pathway-transmission model or to some hemispheric mechanism involved in the perception and/or mediation of activities in the contralateral hemispatial field was determined. Hemispace is not the same as the visual half fields, but refers to the external space to the left or right of body midline. To differentiate between these 2 hypotheses, 24 normal dextrals performed a tactile line bisection task using the left or right hand in each of 3 spatial conditions: at midline, in left hemispace and right hemispace. Both hemisphere-hemispace mechanisms and hemisphere-hand connections contribute to laterality effects. A pseudoneglect phenomenon was observed.
