J. Sergent (1982, Perception & Psychophysics, 31, 451-461; 1983, Psychological Bulletin, 93, 481-512) postulates that the left cerebral hemisphere preferentially extracts higher spatial frequency information, while the right hemisphere preferentially extracts lower frequency spatial information, from the visual scene. According to this view, shorter exposure times favor better right than left hemisphere performance, while longer exposure times favor better left than right hemisphere performance on tachistoscopic laterality tasks. We studied the effects of a threefold variation (40 msec versus 120 msec) in exposure duration, with constant 3-mL luminance, on face recognition and on object naming latency task performances. These are the same stimulus parameters employed by J. Sergent (1983, Psychological Bulletin, 93, 481-512) to demonstrate exposure duration effects in a task requiring the judgment of the sex of models from face photographs. We found the expected LVF superiority on the face recognition task and RVF superiority on the object naming task. There was, however, no influence of exposure duration on the performances. It is concluded that these tasks, which tap established lateralized processing asymmetries, are quite robust in their resistance to exposure time influence.
J. 塞尔让（1982年，《知觉与心理物理学》，第31卷，第451 - 461页；1983年，《心理学公报》，第93卷，第481 - 512页）提出，左脑半球优先从视觉场景中提取较高空间频率的信息，而右脑半球优先提取较低频率的空间信息。按照这种观点，在速示侧性任务中，较短的曝光时间对右脑半球表现的促进作用优于左脑半球，而较长的曝光时间对左脑半球表现的促进作用优于右脑半球。我们研究了在恒定3毫升亮度下，曝光持续时间三倍变化（40毫秒与120毫秒）对人脸识别和物体命名潜伏期任务表现的影响。这些是J. 塞尔让（1983年，《心理学公报》，第93卷，第481 - 512页）所采用的相同刺激参数，用于在一项从面部照片判断模特性别的任务中证明曝光持续时间的影响。我们在人脸识别任务中发现了预期的左视野优势，在物体命名任务中发现了右视野优势。然而，曝光持续时间对表现没有影响。得出的结论是，这些利用既定的侧化加工不对称性的任务，在抵抗曝光时间影响方面相当稳健。
