Forty normal adult volunteers comprising an equal number of right- and left-handed males and females solved simple multiplication problems presented visually to one cerebral hemisphere while various competing stimuli were simultaneously presented to the other hemisphere. The contribution of sex of subject, handedness, hemisphere of presentation and the nature of the competing stimulus in relation to task performance was examined. Each of these variables was significantly associated with correct responses and errors, with few statistically significant interactions. Females and dextrals made more correct responses than males or sinistrals. Type of error depended upon which hemisphere received the problem, with the right hemisphere yielding more errors of commission and the left more errors of omission. Simultaneously presented identical or different arithmetic problems resulted in the most errors compared to the other competing stimuli.
四十名正常成年志愿者，男女数量相等，其中右利手和左利手各占一半，他们在一个脑半球接受视觉呈现的简单乘法问题时，同时向另一个脑半球呈现各种竞争性刺激。研究了受试者性别、利手、呈现问题的脑半球以及竞争性刺激的性质对任务表现的影响。这些变量中的每一个都与正确反应和错误显著相关，几乎没有统计学上显著的相互作用。女性和右利手比男性或左利手做出更多正确反应。错误类型取决于哪个脑半球接收问题，右半球产生更多的主动错误，左半球产生更多的遗漏错误。与其他竞争性刺激相比，同时呈现相同或不同的算术问题导致的错误最多。
