Is this trial a fit for you?
✓Likely a good fit
Adults aged 18 and older who are fluent in English or Chinese and willing to complete self-report measures and a 7-day sleep diary.
✕Probably not a fit
Individuals who do not regularly complete self-report questionnaires or engage in computer-based tasks, or who cannot commit to a 7-day sleep diary, may not benefit from participation.

What this trial studies
This non-clinical observational study explores associations between subjective sleep quality, preferred sleep timing, and chronotype with prosocial decision-making in adults. Participants complete self-report sleep and circadian questionnaires, a 7-day sleep diary, and a brief computer-based Dictator Game where allocations are hypothetical. No sleep disruption, medical treatment, or diagnostic procedures are involved, and compensation is not affected by task choices. Data are collected with pseudonymised participant codes to protect privacy. The primary aim is to describe relationships between natural variations in sleep-related factors and prosocial allocation behavior.
Why it matters
Potential benefit: If successful, findings could improve understanding of how sleep patterns relate to everyday social decisions and wellbeing.
How similar studies have gone: Previous research has shown links between sleep traits and social or cognitive processes, though this exact combination in a Dictator Game context is relatively novel but builds on established associations.
