The results of the experiment offer indirect evidence for the basic hypothesis that the brain self-regulates its own arousal and activation as a function of the intensity and type of ongoing cortical activity. When subjects perform a task which can be assumed to be primarily attended to by the right hemisphere, the result of a supplementary information-processing load seems to be increased arousal. On a task primarily attended to by the left hemisphere, the consequence is increased activation. The evidence is indirect because no measurements have been made of the neurological events and processes which are assumed to intervene in this self-regulation process. Although indirect, the evidence may help to formulate more precise psychological hypotheses about the factors controlling the putative effort system which, according to Pribram and McGuinness in 1975, coordinates the arousal and activation of cerebral processes.
大脑会根据正在进行的皮层活动的强度和类型来自我调节自身的唤醒和激活状态。当受试者执行一项可假定主要由右半球参与的任务时，额外信息处理负荷的结果似乎是唤醒增加。在一项主要由左半球参与的任务中，结果是激活增加。该证据是间接的，因为尚未对假定参与此自我调节过程的神经事件和过程进行测量。尽管是间接证据，但它可能有助于就控制假定的努力系统的因素形成更精确的心理学假设，根据普里布拉姆和麦吉尼斯在1975年的研究，该系统协调大脑过程的唤醒和激活。
