Objective/Background: The impact of midday napping on neurocognitive function in adolescents has not been well established. This study aimed to investigate the relationship between self-reported midday-napping behaviors and neurocognitive function in early adolescents. Participants: The sample was comprised of 363 early adolescents (12.00 ± 0.38 years old) from Jintan, China. Methods: Midday napping, nighttime sleep duration, and sleep quality were measured by self-reported questionnaires. Neurocognitive function was measured by the Penn Computerized Neurocognitive Battery (accuracy and reaction times). Generalized linear regression was used to analyze the relationships. Results: Sixty-four percent of our sample took more than 3 naps per week, and 70.11% reported nap durations of over 30 min. Participants with higher frequencies or longer durations of midday napping reported significantly better nighttime sleep quality (p < 0.05). Adjusted models showed that frequent nappers (5–7d/week) were significantly associated with heightened accuracy on tasks that measured sustained attention and nonverbal reasoning and faster reaction times on spatial memory compared with other frequency groups (ps < 0.05). For napping duration subgroups, early adolescents who took naps of any length were estimated to have faster reaction speeds on the sustained attention task compared with participants who never napped (ps < 0.05). However, only nappers with a moderate duration (31–60 min) tended to achieve both faster speeds (β = −38.28, p = 0.02) and better accuracy (β = 3.90, p = 0.04) on the sustained attention task. Conclusions: Our findings suggest that there is an association between habitual midday napping and neurocognitive function in early adolescents, especially in China, where midday napping is a cultural practice.
