title: Factors and processes in children's transitive deductions.
abstract: Transitive tasks are important for understanding how children develop socio-cognitively. However, developmental research has been restricted largely to questions surrounding maturation. We asked 6-, 7- and 8-year-olds (N= 117) to solve a composite of five different transitive tasks. Tasks included conditions asking about item-C(associated with the marked relation) in addition to the usual case of asking only about item-A(associated with the unmarked relation). Here, children found resolving item-Cmuch easier than resolving item-A, a finding running counter to long-standing assumptions about transitive reasoning. Considering gender perhaps for the first time, boys exhibited higher transitive scores than girls overall. Finally, analysing in the context of one recent and well-specified theory of spatial transitive reasoning, we generated the prediction that reporting the full series should be easier than deducing any one item from that series. This prediction was not upheld. We discuss amendments necessary to accommodate all our earlier findings.
