Data of cognitive task performance and illuminance collected by a smartphone app

Data was collected by a smartphone app (Brighter Time) to capture measures of cognitive performance and light exposure during everyday life. The app incorporated a psychomotor vigilance (PVT), an N2-back, and a visual search task with questionnaire-based assessments of sleep timing. The app also measured illuminance during task completion using the smartphone’s intrinsic light meter. Data was collected in a pilot feasibility study of Brighter Time based upon 91 week-long running Brighter Time on their own smartphones. Data: ambient light (log lx), kss score (Karolinska Sleepiness Scale), median reaction times (ms), number of lapses in PVT (>500ms), hit rate (%), false alarm rate (%), 90th percentile of reaction times (ms), 10th percentile of reaction times (ms), inverse efficiency score, d-prime for N-back task, search efficieny slope for visual search task.

数据由一款智能手机应用（Brighter Time）采集，旨在捕捉日常生活中认知表现与光照暴露的量化指标。该应用整合了心理运动警觉性测试（PVT）、N2-back任务、视觉搜索任务，以及基于问卷的睡眠定时评估。应用还通过智能手机内置的测光仪，在任务执行期间测量光照度。数据来自Brighter Time的一项初步可行性研究，基于91名参与者在个人智能手机上连续运行该应用一周所产生的记录。数据包含：环境光（对数勒克斯）、KSS得分（卡罗林斯卡嗜睡量表，Karolinska Sleepiness Scale）、反应时间中位数（毫秒）、PVT任务中的失误次数（>500毫秒）、命中率（%）、误报率（%）、反应时间第90百分位数（毫秒）、反应时间第10百分位数（毫秒）、逆效率得分、N-back任务的d-prime值（d-prime）、视觉搜索任务的搜索效率斜率。
