Good sleep quality is important to cognition, physical health, mental well-being, and creativity—factors critical to academic and professional success. But, undergraduate students often report engaging in short, irregular, and poor-quality sleep. Anecdotal and questionnaire data suggest that poor sleep habits might be prevalent in students who are in studio- or project-based majors that implicitly encourage consecutive nights of disrupted sleep to complete projects. We investigated sleep quantity and quality using both objective measures (wristband actigraphy monitoring) and subjective measures (sleep diary) in 28 interior design undergraduate students for a 7-day period. Our primary aim was to measure sleep quantity (total sleep time) and quality (e.g., nighttime awakenings) and to compare whether undergraduate interior design students' objective measures of sleep (actigraphy) differed from their subjective measures (sleep diary). The secondary aim was to investigate detrimental outcomes of poor sleep habits on laboratory-based measures of cognitive function (symmetry span, prospective memory, Raven's progressive matrices, remote associates task) that were administered pre- and poststudy. We found that the interior design students in our study overestimated their total sleep time by 36 minutes, that 79% of students slept for fewer than 7 hours at least three nights per week, and that many students cycled between nights of restricted/short sleep and recovery/long sleep. Importantly, students who maintained short sleep durations, highly variable night-to-night sleep durations, or had fragmented sleep (i.e., waking after sleep onset) demonstrated pre- to poststudy declines on the laboratory measure of creativity (remote associates task). These findings suggest the need for further investigations, which may lead to a broader discussion of studio culture and the role of the “all-nighter,” both in professional practice and in design education.

在基于工作室的课程中睡觉：创造力任务表现的结果

良好的睡眠质量对认知、身体健康、心理健康和创造力很重要——这些因素是学业和职业成功的关键。但是，本科生经常报告睡眠时间短、不规律且睡眠质量差。轶事和问卷数据表明，在以工作室或项目为基础的专业的学生中，不良的睡眠习惯可能普遍存在，这些学生暗中鼓励连续晚上中断睡眠以完成项目。我们使用客观测量（腕带活动监测）和主观测量（睡眠日记）对 28 名室内设计本科生进行为期 7 天的睡眠数量和质量调查。我们的主要目的是衡量睡眠数量（总睡眠时间）和质量（例如，夜间醒来），并比较本科室内设计学生是否 睡眠的客观测量（活动记录）与其主观测量（睡眠日记）不同。次要目的是在研究前和研究后进行的基于实验室的认知功能测量（对称跨度、前瞻记忆、Raven 渐进矩阵、远程助理任务）调查不良睡眠习惯的不利结果。我们发现，我们研究中的室内设计专业学生将他们的总睡眠时间高估了 36 分钟，79% 的学生每周至少有 3 个晚上的睡眠时间少于 7 小时，而且许多学生在睡眠受限/睡眠时间短的夜晚和恢复/长时间睡眠。重要的是，睡眠时间短、夜间睡眠时间变化很大或睡眠碎片化的学生（即，入睡后醒来）在实验室创造力测量（远程助理任务）上表现出研究前到研究后的下降。这些发现表明需要进一步调查，这可能会导致对工作室文化和“通宵”在专业实践和设计教育中的作用进行更广泛的讨论。
