Children's Prehension: Normative Data for the Children's Box and Block Test

Abstract

To establish norms for gross manual dexterity of school-age children, 113 Ss, aged 7, 8, 9 yr., were given the Children's Box and Block Test, which yields a performance index for each hand. (a) For 7-yr.-olds, the mean scores for dominant hand were 61.8 for boys, 62.7 for girls; and 57.7 for boys' and 59.4 for girls' non-dominant hands. (b) The mean scores for dominant hand of 8-yr.-old boys and girls were 66.0 and 67.2 respectively; for the non-dominant hand 61.9 and 63.3. For dominant and non-dominant hands of 9-yr.-old boys, scores were 71.0 and 62.3; for the girls 68.0 and 64.6. Test-retest reliability varied from .78 to .91.
