In this study, we aimed to update a previous meta-analysis about the correlation between circadian preference and intelligence. Our literature search identified a large number of new studies, resulting in an increase of over 100% in the number of studies and over 400% in the number of involved participants (total k =\u00a030, total N =\u00a011160) over the previous meta-analysis, sampling a much wider age range from children to adults in late middle age. Our meta-analysis revealed no significant link between morningness and intelligence (r\u00a0=\u00a0\u22120.008) when the entire sample was studied, and no evidence for publication bias. This overall effect, however, obscured the moderating effect of age. The morningness-intelligence correlation decreased with mean sample age (R2<\/sup>\u00a0=\u00a054%), ranging from a non-significant positive trend in children and adolescents to a significant negative correlation after young adulthood. Eveningness was positively correlated with intelligence (r\u00a0=\u00a00.056), but this finding is based on a more age-restricted sample and only reached significance with some model specifications. We hypothesize that the age-moderated correlation between circadian preference and intelligence reflects social effects, where more intelligent individuals are more able to adjust their daily schedules to their natural circadian rhythm.<\/p>\n KEYWORDS: circadian preference, chronotype, IQ, cognitive ability, meta-analysis<\/p>\n","protected":false},"excerpt":{"rendered":" Chronobiology International Published online: 20 May 2021 P\u00e9ter P.
