Much previous international research has demonstrated links between general school attainment and active engagement with music. The research reported here compared the change in examination outcomes in English and mathematics in national examinations at ages 11 and 16 of instrumentalists and non-instrumentalists. Data from 701 pupils showed statistically significant differences in examination outcomes between instrumentalists and non-instrumentalists, which was also related to the duration of learning and the instrument played. Instrumentalists had greater change scores in mathematics, but not English, although instrumentalists of lower socio-economic status showed greater change in both subjects. The implications for music education are discussed.

An experiment was conducted using a human instrumental learning task with the goal of evaluating the mechanisms underlying the deleterious effect of context-switching on responding to an unambiguous stimulus when contexts are informative to solve the task. Participants were trained in a context-based reversal discrimination in which two discriminative stimuli (X and Y) interchange their meaning across contexts A and B. In context A, discriminative stimulus Z consistently announced that the relationship between a specific instrumental response (R1) and a specific outcome (O1) was in effect. Performance in the presence of stimulus Z was equally deteriorated when the test was conducted outside the training context, regardless of whether the test context was familiar (context B) or new (context C). This result is consistent with the idea that participants code all the information presented in an informative context as context-specific with the context playing a role akin to an occasion setter.
