A gender difference in visual-spatial ability in 4-year-old children: effects of performance of a kinesthetic acuity task

Article Abstract:

Boys exhibit superior performance to that of girls on kinesthetic acuity test (KAT) in the presence of extra visual-spatial cues and on three-dimensional block design test. This gender difference on performance disappears when the extra clues are removed. Measures on KAT exhibit a strong positive correlation with those of the block design test. Gender difference in KAT in the presence of clues suggests the differential use of the cues by boys and girls, rather than an actual difference in kinesthetic acuity.

Dysgraphia in children: lasting psychomotor deficiency or transient developmental delay?

Article Abstract:

Research shows that the discriminating factor in children with handwriting deficiency is spatial accuracy control as opposed to size control or allograph retrieval. Power Spectral Density Analysis indicates that poor writers have significantly noisier movements than proficient writers, and are simultaneously less accurate. The research involved 16 young children, with a longitudinal design used to identify those with dysgraphia and those demonstrating normal psychomotor development.

Understanding transitivity of a spatial relationship: a developmental analysis

Article Abstract:

Results from a study of 82 children, wherein sets of two block towers represented tasks of transitive inference, revealed the existence of step-by-step algorithms empowering these children to solve progressively difficult transitive inference tasks. Eight-year-olds performed comparatively better than six-year-olds in dealing with transitive inference tasks of a complex nature.
