RT = reaction times.

For each variable, the Pearson's correlation coefficient and two-tailed p value of the zero-order correlation have been given. For the multiple regression, the unstandardized regression coefficient has been given along with its standard error. The t-test value of the regression coefficient is also shown along with the part correlation.
