本文探讨了信息的横向速示对完整大脑半球加工效率的影响。考虑到理解每个半球的特定能力的基础过程可能需要，作为初步步骤，大脑操作的输入特性的规范，概述了简要刺激视网膜周边以在大脑中表示信息的解剖学，生理学和心理物理学后果，特别是关于刺激的空间-频率频谱组成。视网膜偏心率和短暂的曝光时间会聚在一起，使信息的表示与大脑正常运作的信息有质的不同，这限制了对大脑半球正常功能的研究结果的解释。对与这些问题相关的实证研究结果的回顾和讨论表明，程序变量的操纵可能会对大脑半球的处理效率产生不同的影响，并表明一个给定的视野不对称模式可能会被众多以复杂方式相互作用的变量所过度决定。
This paper examines the implications of lateral tachistoscopic presentation of information for the processing efficiency of the intact cerebral hemispheres. Considering that the understanding of the processes underlying the particular competences of each hemisphere may require, as a preliminary step, the specification of the characteristics of the input on which the brain operates, anatomical, physiological, and psychophysical consequences of briefly stimulating the retinal periphery for the representation of information in the brain are outlined, with special reference to the spatial-frequency spectral composition of the stimuli. Retinal eccentricity and brief exposure duration converge to making the representation of information qualitatively different from the information that the brain normally operates on, which constrains the interpretation of findings with respect to the normal functions of the cerebral hemispheres. A review and discussion of empirical findings relevant to these issues suggest that manipulation of procedural variables may differentially affect the processing efficiency of the cerebral hemispheres and indicate that a given pattern of visual-field asymmetry may be overdetermined by a multitude of variables interacting in complex ways.
