This meta-analysis examined the relationship between prenatal maternal stress and/or anxiety and the outcomes of children aged 3 months to 9 years. Of the 8754 studies published before June 2021 that were synthesized, 17 conducted in Western countries were included in the meta-analysis (N[subscript total] = 23,307; M[subscript males] 54%;…

In a series of meta-analyses, paternal sensitivity was associated with children's (age range: 7 months-9 years) overall cognitive functioning (N = 3,193; k = 23; r = 0.19), including language skills (k = 9; r = 0.21), cognitive ability (k = 9; r = 0.18), and executive function (k = 8; r = 0.19). Paternal sensitivity was not associated with…

Numerous studies show that children's language ability is related to false-belief understanding. However, there is considerable variation in the size of the correlation reported. Using data from 104 studies (N=8,891), this meta-analysis determines the strength of the relation in children under age 7 and examines moderators that may account for the…

Maintains that the results of Wellman, Cross, and Watson's meta-analysis on the false belief task are perfectly compatible with "early competence" accounts that posit a specific, innate, and possibly modular basis for theory of mind. Asserts that Wellman and colleagues' arguments against such views stem from mistaken assumptions…

Conducted meta-analysis to examine empirical inconsistencies and theoretical controversies concerning false-belief tasks and understanding about mental states. Found that a combined model including age, country of origin, and four task factors accounted for 55 percent of the variance in false-belief performance. Findings are consistent with…

Maintains that authors' meta-analytic findings make early competence accounts of theory of mind increasingly unlikely. Asserts that findings argue against executive function expression accounts, including that advocated by Scholl and Leslie (PS532407). Explains that meta-analytic findings directly contradict Scholl and Leslie's predictions…

Meta-analysis of the A-not-B error was conducted, using logistic regression, on studies conducted before September 1997. Results replicated earlier findings, with exception that the number of trials at the A location was a significant predictor, and the number of locations was a significant predictor of the proportion of infants who searched…
