Infants' ability to mentally track the orientation of an object during a hidden rotation was investigated (N = 28 in each experiment). A toy on a turntable was fully covered and then rotated 90°. When revealed, the toy had turned with the turntable (probable event), remained at its starting orientation (improbable event in Experiment 1), or…

Understanding how responses become prepotent is essential for understanding when inhibitory control is needed in everyday behaviour. We investigated prepotency in the grass-snow task--in which a child points to a green card when the experimenter says "snow" and a white card when the experimenter says "grass". Experiment 1 (n =…

Five experiments using the visual habitation paradigm with 158 infants demonstrated that these 10-month olds did not use property/kind information to establish representations of 2 numerically distinct objects, a finding that provided support for the object-first hypothesis. (SLD)

Described are the history of the study of language disabilities, briefly outlining the work of Samuel Orton, Judson Herrick, Adolph Meyer, and Paul Schilder; Lauretta Bender's development of the Bender Visual Motor Gestalt Test; and the basic principles of language disorders, including familial patterns, maturation lag, plasticity, and nonfixated…

For the age range tested there is a lag between the perception and production of certain facial expressions. (Authors)

Children referred for psychological evaluations of completed the Bender-Gestalt and then reproduced designs from memory. Numbers of designs recalled increased with age and Performance Intelligence Quotient. The importance of developmental level in evaluation and establishment of cut-off recall scores for designs were discussed. (Author/RD)

A series of studies with adults resulted in a standardized test to assess children's comprehension of main ideas in simple narratives. The test, utilizing stories from the WISC-R picture arrangement task, was then employed in a developmental investigation with second, fifth, and eighth grade students. Each student completed the WISC-R arrangement…

This study concerns children's understanding of spatial relationships and their expression in drawings and photographs. Sixty children (ages 5, 8, and 11) were asked to discriminate and reproduce three types of depth relationships in either drawings or photographs: enclosure, where a larger object is placed directly behind a smaller object;…

Whether a developmental dissociation exists between direct and indirect tests of picture memory was studied using 29 second graders and 29 sixth graders given a 1-day retention interval. Sixth graders performed better than second graders when memory was tested directly, but the performance of both groups was comparable when memory was tested…

The Berry Developmental Test of Visual Motor Integration was devised as a measure of the degree to which visual perception and motor behavior are integrated in young children, measured by the copying of geometric forms. In this study, 64 three-year-old children were tested individually to investigate (1) whether there is a correlation between…

Discusses the growing importance of test collections in academic libraries and provides resources for test collection development. Tests in the following areas are described in detail: academic; achievement and aptitude; child development; educational development and preschool readiness; intelligence; personality; sensory motor skills; special…
