Primary Outcome Measures

Name	Time	Method
Preliminary analysis revealed that the 12-session training had a positive influence on children’s performance on the task. The number of correctly found end-points, attained by adequately following the corresponding path, increased for both training groups. There was however a difference in the amount of increase between the two groups. On average, the group that has trained without the magnifier performed twice as good. That is, in the post-test they found twice as much correct end-point figures as compared to the pre-test. In the group that has trained with the magnifier, this number was four times as high. Now we are studying the rich data we collected to uncover the relevant variables that determine children’s progression and the differences between the groups. In addition we are looking for a possible transfer of this progression to other domains of their development (e.g., fine-motor skills).
