Abstract
A 25-item handedness performance test was administered twice, at a one-month interval, to 85 elementary school children (60 right handers and 25 left handers in two different age groups). The laterality quotient distribution for right handers was more skewed and significantly different in central tendency and shape than the left handers' distribution. Mean point-biserial item-test correlation was 0.85. The test-retest correlation coefficient for the whole group was 0.79.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
