这项初步研究的目的是调查光疗法是否能改善健康受试者的注意力、记忆力和语言的神经认知表现。10名受试者用白色强光治疗5天，对照组10名未接受治疗的受试者用一系列神经认知测试进行评估，这些测试包括Stroop颜色词干扰测试、言语流畅性测试、故事回忆测试和词对回忆测试。分析显示，两组的认知评分均有所改善，尽管在所有认知测试中，光治疗组基线和终点之间的平均差异评分显著更大。这些初步结果表明，短期的强光可能对认知功能产生有益的影响。
The aim of this pilot study was to investigate whether light therapy improves healthy subjects' neurocognitive performance of attention, memory, and language. Ten subjects were treated with white bright light for 5 days and a control group of 10 with no treatment were assessed with a battery of neurocognitive tests which included the Stroop Colour Word Interference Test, the Verbal Fluency Test, the Story Recall Test, and the Word Pairs Recall Test. Analysis showed improvements in cognitive scores in both groups, although on all the cognitive tests the mean difference scores between baseline and endpoint were significantly larger in the light-treated group. These preliminary results suggest that short-term bright light may exert beneficial effects on cognitive functions.
