Presents meta-analysis evidence of the association between paternal sensitivity and infant-father attachment from eight studies with 546 families (combined effect size r = 0.13). A meta-analysis of 950 families from 14 studies found an overall correlation of 0.17 between infant-mother and infant-father attachment. Presents a data-based model of…

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 it is important to distinguish theory testing from effect-size evaluation when considering the impact of mothering on attachment security. Contends that it is possible that the De Wolff and van IJzendoorn meta-analysis both over- and underestimates mothering effects, as would be the case if infants varied in their susceptibility to…

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…

Argues that although meta-analysis makes an important contribution to summarizing attachment studies, it limits the conceptual understanding to simple causal models and ignores family systems models that could illuminate the development of secure and insecure attachment. Maintains that fathers' role in attachment and the impact of the quality of…
