Correlation of ambient air temperature and cognitive performance: A systematic review and meta-analysis

摘要: Abstract Despite their impact on work performance, cognitive responses to thermal variations in buildings have not been accurately quantified. Practical limitations individual laboratory experiments with limited participants often cause low statistical power and restrict generalizability. Thus, inconsistencies studies motivate summary reviews meta-analyses. The objective of this study is estimate the correlation between ambient air temperature performance through a systematic literature review. We identified experiment reports published 1980 2018, out which 45 passed targeted inclusion exclusion criteria set forward by scope study. To obtain effect statistics, 28 were included single analysis conducted use Comprehensive Meta-Analysis software. Under conditions fixed clothing values, weighted mean 4.34 °C, 10.04 °C, 26.68 °C increase control show about % 0.40, 5.37, 7.97 reductions respectively. Heat stress causes most significant decline attention-demanding tasks. results an overall both speed accuracy measures due changes temperature.
