Maintains that Demetriou and his colleagues' project shows how developmental scientists can assess concepts from multiple frameworks and relate them through explicit modeling and targeted research to build explanations powerfully grounded in data and theory. Presents doubts related to specific conclusions because of issues related to the design of…

Conducted spectrum analysis of standard and vociferous cries from infants with Wessel's colic, non-Wessel's colic, and comparison infants.

After feedings, problematic criers had greater percentage of dysphonation in…

Three studies used interspecies adoption stories to examine children's understanding of the role of birth in determining animal properties and species identity. Found that most 4- to 7-year olds could reliably judge that babies would be of the same species as birth parents, but were unable to attribute properties of adoptive parents. (Author/KB)

Studied effects of presence of novel social category on intergroup attitude formation in 6- to 9-year olds. Found that after four weeks of the functional use of color groups, children's attitudes showed consistent biases favoring their own group. Children with higher self-esteem showed higher intergroup stereotyping than did children with lower…
