Abstract
Mental rotation is an important spatial skill However there is controversy concerning its early development and susceptibility to intervention In the present study we assessed individual differences in the mental rotation abilities of children between 3½ and 5½ years of age using a touch screen paradigm to simplify task demands A figure or its mirror image was presented in 8 different orientations and children indicated in which of two holes the figure would fit by touching one of the holes on the screen Task instructions were varied in three conditions giving the children the opportunity to gather manual or observational experience with rotations of different stimuli or giving no additional experience Children’s error rates and response times increased linearly with increasing angular disparity between the figure and the hole by the age of 5 years but 4yearolds were found to respond at chance for all angular disparities despite the use of a touch screen paradigm Both manual and observational experience increased the response accuracy of 5yearolds especially for children already performing well However there was no effect on 4yearolds Results point to an emerging readiness to use mental rotation and profit from observational and manual experience at age 5
