Questioning others is one of the most powerful methods that children use to learn about the world. How does questioning develop? How is it socialized? And how can questioning be leveraged to support learning and education? In this volume, some of the world's leading experts are brought together to explore critical issues in the development of…

Two experiments using the habituation-dishabituation paradigm examined infants' ability to form and retrieve a basic-level category. Results indicated that infants categorized when tested immediately and after a five-minute delay. (PCB)

Concepts important to cognitive development in children can be classified according to several levels. At level 1, concepts are equivalent in structural complexity to binary relations and univariate functions. At level 2, concepts are equivalent to compositions of binary relations, binary operations, and bivariate functions. At level 3, concepts…

Subtypes of nonsocial play were examined for matched groups of young typically developing children and children with mild developmental (cognitive) delays. Findings indicated that the nonsocial play of these children can be characterized as multidimensional in a manner similar to that of typically developing children. However, context did not…

This study compared three methods for identifying non-mainstream dialect use: listener judgment ratings, type-based counts of non-mainstream pattern use, token- based counts. Correct dialect classifications were made for 88 to 97 percent of participants, although regression algorithms had to be applied to the type- and token-based results. For…

This study evaluated the accuracy of automated methods of grammatical categorization ("tagging") of transcribed conversational language samples from 30 normally developing children. On a word-by-word basis, automated accuracy levels averaged 95.1%; accuracy of tagging whole utterances averaged 77.7%. Results suggest that further improvement of…

Evaluates some possible reasons for the occurrence and eventual correction of children's naming errors in an experiment in which two-, four-, and six-year-olds learned two artificial object names in succession. (HOD)
