The best-fitting latent factor model linking individual differences in latent working memory abilities, η1 and η2, to individual differences in speech recognition ability, ηspeech. (A) The parameters linking individual differences in latent factors to performance in each task and task condition are depicted as in Figures 3 and 4. In this model, the regression coefficient β1 was fixed to 1 because preliminary models failed to converge when attempting to approach this boundary value. (B) The two latent individual difference factors obtained by this model fit are depicted as in Figure 4B for participants who completed both the memory and speech tasks.
