CCTw = Camel and Cactus words; CCTp = Camel and Cactus pictures; WPM = word–picture matching.

All from the Cambridge Semantic Battery (Bozeat et al., 2000). W‐P and S‐P are word–picture and sound–picture matching tasks from the Environmental Sounds Task (Bozeat et al., 2000). Each line represents a separate analysis. In each analysis, we assessed the value of one task (the DV) in relation to the group and while controlling for the influence of performance on another task (the covariate). Significant covariate results suggest an effect of task performance influencing performance on another task (the DV). Where this interacts significantly with group, this suggests a difference in the influence of this covariate between the groups. Values presented are the F‐statistics.
