In this experiment, which is basically a replication of an earlier experiment done in 1988, we tested the hypothesis that the brain self-regulates its own arousal and activation. When subjects perform a putative right-hemisphere task (visuospatial), the effect of a supplementary information-processing load is supposed to lead to a delayed reaction. The opposite is supposed to be true in a putative left-hemisphere task (semantic). The former effect is supposed to be the result of increased arousal, the latter is that of increased activation. In the present experiment the reactions subject to experimental treatment are compared with control reactions of the same subject. This was not the case in the earlier experiment. Still other improvements of the experimental design were made. The results clearly confirm the earlier findings. Additional evidence is offered to strengthen the plausibility of the basic hypothesis.
在本实验中，其本质上是对1988年进行的一项早期实验的重复，我们检验了大脑自我调节自身唤醒和激活的假设。当受试者执行一项假定的右半球任务（视觉空间任务）时，额外信息处理负荷的影响应该会导致反应延迟。在一项假定的左半球任务（语义任务）中，情况应该相反。前一种效应应该是唤醒增加的结果，后一种效应是激活增加的结果。在本实验中，将接受实验处理的反应与同一受试者的对照反应进行比较。早期实验并非如此。实验设计还有其他改进。结果清楚地证实了早期的发现。提供了额外的证据来增强基本假设的可信度。
