Across tasks, results revealed that although the ability to learn from positive/negative feedback did not differ between the two groups, the learning of reinforcement contingencies was poorer in the dyslexia group compared with the neurotypicals group. Furthermore, in novel test pairs where previously learned information was presented in new combinations, dyslexic individuals performed similarly to neurotypicals.

During the acquisition phase, participants with dyslexia did not differ significantly from the control group in the number of trials required to reach criterion and performance did not differ significantly between the two groups during the first phase of learning. ….However, results from the post-acquisition test phase indicated reduced learning of reinforcement contingencies in the dyslexia group compared with the control group. This pattern was confined to trained items, as the ability to generalize from repeated exposure to negative/positive outcomes was comparable across the two groups.
