LORDELO, Eulina Rocha et al. Parental investment and child development. Estud. psicol. (Natal) [online]. 2006, vol.11, n.3, pp.257-264. ISSN 1678-4669.  https://doi.org/10.1590/S1413-294X2006000300002.

According to the parental investment theory, it would be expected an association between maternal family environment and her reproductive behavior and, as a consequence, her patterns of parental investment on her children, with effects on their development. This study aimed to verify that association, in a sample of 37 mothers and their children (one to four years old), in a poor neighborhood of Salvador, in the state of Bahia, Brazil. We studied the family and reproductive history of the mothers and assessed the cognitive development of children, through Bayley and WIPPSI-R scales, in four assessments during three years. We found correlation between the raising environment of the mother and her subsequent reproductive patterns. These patterns were related to cognitive development of children, favoring children whose mothers started their reproductive life later. The results are, in general, compatible with the parental investment theory. Limitations of the study and future perspectives are discussed.

Palavras-chave : parental investment; cognitive development; reproductive strategies; evolutionary psychology.
