Figure 2. Accuracy data (percentage of errors) for zigzag novel words (NW) as a function of testing sessions, separately for the two groups of children.

Filled circles: dyslexic children; open circles: controls. Accuracy data were fit by power functions separately for the groups of dyslexic children (continuous lines) and controls (dotted lines). The equations describing the learning curves were y = 20.5x^−.42 + 0 (4) and y = 17.5x^−0.60 + 0 (5), for dyslexic children and controls, respectively. The bars represent accuracy for untrained novel words at the post-training session. Note that also for accuracy learning by training was higher in controls than dyslexic children; however, generalization to untrained items was low for both groups.
