Left- and right-handed children's drawing performance: is there any difference?

The aim of the present study was to investigate the effect of hand preference on children's drawing development. An equal number of left- and right-handed children (N = 182), aged 7 to 12 years were asked to complete four different drawing tasks. During the drawing process, directionality of horizontal, vertical, and circular strokes as well as sequencing was recorded. Each drawing was scored according to the developmental stage to which is corresponded. It was found that drawing performance improved with age, irrespectively of hand preference and sex. In other words, left- and right-handers' drawing performance across the four tasks was not found to differ significantly. The only consistent difference between the two groups involved was in the production of horizontal lines. The results are discussed in terms of implications for questions about the lack of differences in left- and right-handed children's drawing performance.

Visual memory deficit in children with dysgraphia.

This study evaluates the performance of children with diagnosed dysgraphia and a control group on the Rey-Osterrieth Complex Figure test. A group of 48 Greek elementary school children aged 6.6 to 12.5 years who were in regular school placement participated. All had been diagnosed with dysgraphia, using the writing scale of the Luria-Nebraska Neuropsychological Battery and were matched with a control group of 48 for sex, age, grade, and handedness. Both groups were administered the test, and the children were examined during copying and mnemonic reproduction of the complex figure. Analysis indicated that there were no significant differences between dysgraphic and nondysgraphic groups during the copying task but the dysgraphic group performed significantly lower during mnemonic reproduction of the Rey-Osterrieth Complex Figure. These results suggest that children with dysgraphia possibly suffer from cognitive difficulties that influence visual memory more than visuomotor skills.
