The Effect of an Induced Selective Increase in Head Temperature Upon Performance of a Simple Mental Task
通过温控头盔使受试者头部温度升高1.01°C，发现其完成简单加法任务的速度显著提升，且错误率未受影响，表明局部升温可促进行为任务的处理速度。
Subjects performed a simple mental addition task under three counter-balanced conditions of a head temperature manipulation. In the heating condition, a temperature-controlled helmet induced a 1.01°C rise in head temperature as measured in the deep auditory meatus. A placebo condition consisted of helmet application but not activation, and the control condition monitored performance in the absence of the helmet. Results indicated that significantly more additions were accomplished under the heating compared with the two unvarying, non-heating conditions. This was not a trade of speed for accuracy, since the thermal manipulation exerted no significant effect on error rate. The work suggests that processing rate in a behavioral task is facilitated by the localized temperature increase.
