Three experiments were conducted using tachistoscopic circular displays of English and/or Hebrew letters that were equidistant from a fixation point. It was found that: (1) Irrespective of native language, English or Hebrew, subjects initiate their reports of English letters from the upper left quadrant and of Hebrew letters from the upper right quadrant of the display. In addition, subsequent letter reports come mostly from the same quadrant. (2) Although Experiments 1 and 2 indicated that direction of reporting might be a function of display language, Experiment 3 provided data to show that direction of reporting was a function of the position of the first response and not the display letter language that engaged that response, nor the display language of adjacent letters. It was suggested that the typical asymmetries reported in the literature, such as right visual field superiority for word stimuli, are the result of a particular set of stimulus conditions (e.g., hemifield presentations) and response requirements (e.g., reaction time and correct recognition). When stimulus conditions and response requirements are made compatible with previously overlearned behaviors, the potential influences of cerebral asymmetries are overshadowed by external stimulus control.
进行了三项实验，使用速示器呈现与注视点等距的英文和/或希伯来字母圆形显示。结果发现：(1) 无论母语是英语还是希伯来语，受试者报告英文字母时都从显示的左上方象限开始，报告希伯来字母时从右上方象限开始。此外，随后的字母报告大多来自同一象限。(2) 虽然实验1和2表明报告方向可能是显示语言的函数，但实验3提供的数据表明，报告方向是第一个反应位置的函数，而不是引发该反应的显示字母语言的函数，也不是相邻字母的显示语言的函数。有人提出，文献中报道的典型不对称现象，如单词刺激的右视野优势，是特定一组刺激条件（如半视野呈现）和反应要求（如反应时间和正确识别）的结果。当刺激条件和反应要求与先前过度学习的行为相匹配时，大脑不对称的潜在影响就会被外部刺激控制所掩盖。
