The following information is provided in the table: task or score name (first column); name of the term in the regression model (second column); coefficient estimate and standard error within round brackets (third column); t-value associated with the term (fourth column); p-value with stars “

^*” denoting significant terms (fifth column); adjusted R² (sixth column).
