Table 4:

Sigma correlations across tasks within and across domains. The correlation coefficient is presented in the bottom triangle and the corresponding 95% credible interval in the top. Processing speed tasks are highlighted in yellow, working memory tasks in orange, episodic memory tasks in green.
