大量的实验工作试图确定大脑偏侧化的可靠行为预测因子。偏爱利手一直是最受欢迎的预测指标，但最近的一些报告表明，偏爱脚步可能是功能偏侧的更准确的预测指标，特别是在左撇子人群中。这项研究试图通过有选择地招募具有“交叉”横向偏好(右手和左脚或左手和右脚)或“非交叉”横向偏好(右手和右脚或左手和左脚)的个体来验证这一说法。情绪知觉的偏侧化采用双分情绪词测验(EWT)的两个模块进行评估，并使用自填式问卷评估对利手和脚的侧向偏好。在双耳任务中，耳朵优势与偏足有显著差异(P=0.003)，但与偏手无显著差异。大脑偏侧化可能更多地与脚步有关，而不是其他侧向偏好。(C)1998由爱思唯尔科学有限公司出版。版权所有。
A tremendous amount of experimental work has attempted to identify reliable behavioural predictors of cerebral lateralization. Preferred handedness has been the most popular predictor, but some recent reports suggest that preferred footedness may serve as a more accurate predictor of functional laterality, especially in the left-handed population. The present study sought to test this claim by selectively recruiting individuals with either 'crossed' lateral preferences (right-handed and left-footed or left-handed and right-footed) or 'uncrossed' lateral preferences (right-handed and right-footed or left-handed and left-footed). Lateralization of emotional perception was assessed with two blocks of the dichotic Emotional Words Test (EWT), and lateral preference for both handedness and footedness was assessed using self-report questionnaires. Ear advantage on the dichotic task varied significantly with preferred foot (P=0.003), but not with preferred hand. Cerebral lateralization may be more related to footedness than to other lateral preferences. (C) 1998 Published by Elsevier Science Ltd. All rights reserved.
