The aim of the study was to determine the effect of a temperature of 29°C on performance in tasks involving different cognitive demands and to assess the effect on perceived performance, subjective workload, thermal comfort, perceived working conditions, cognitive fatigue, and somatic symptoms in a laboratory with realistic office environment. A comparison was made with a temperature of 23°C. Performance was measured on the basis of six different tasks that reflect different stages of cognitive performance. Thirty-three students participated in the experiment. The exposure time was 3.5 h in both thermal conditions. Performance was negatively affected by slightly warm temperature in the N-back working memory task. Temperature had no effect on performance in other tasks focusing on psychomotor, working memory, attention, or long-term memory capabilities. Temperature had no effect on perceived performance. However, slightly warm temperature caused concentration difficulties. Throat symptoms were found to increase over time at 29°C, but no temporal change was seen at 23°C. No effect of temperature on other symptoms was found. As expected, the differences in thermal comfort were significant. Women perceived a temperature of 23°C colder than men.
本研究旨在确定 29°C 的温度对涉及不同认知需求的任务表现的影响，并评估其对感知表现、主观工作量、热舒适度、感知工作条件、认知疲劳和躯体症状的影响，在具有现实办公环境的实验室中进行。将其与 23°C 的温度进行了比较。表现是基于六个不同的任务来衡量的，这些任务反映了认知表现的不同阶段。33 名学生参加了实验。在两种热条件下，暴露时间均为 3.5 小时。在 N 回工作记忆任务中，稍高的温度会对表现产生负面影响。在其他专注于心理运动、工作记忆、注意力或长期记忆能力的任务中，温度对表现没有影响。温度对感知表现没有影响。然而，稍高的温度会导致注意力难以集中。在 29°C 时，喉咙症状随着时间的推移而增加，但在 23°C 时没有观察到时间变化。未发现温度对其他症状有影响。正如预期的那样，热舒适度的差异非常显著。女性比男性感觉 23°C 的温度低。
