Right- and left-handed subjects responded to a task which required identification of signal events embedded in four-beat dichotic rhythm patterns. Left-handed subjects reported a significantly greater number of signals from both ears than did right-handed subjects. The results suggested that left-handed subjects may be better able to analyze simultaneous stimuli and integrate differential information from them into a coherent response structure. The data further support a bi-dominant theory of left-handedness.
右利手和左利手受试者对一项任务做出反应,该任务要求识别嵌入四拍双耳节奏模式中的信号事件。左利手受试者报告来自双耳的信号数量明显多于右利手受试者。结果表明,左利手受试者可能更善于分析同时出现的刺激,并将来自这些刺激的差异信息整合到一个连贯的反应结构中。这些数据进一步支持了左利手的双侧优势理论。
