Table 7.
Multiple linear regression models predicting behavioral test scores from naming abilities. The linear coefficient associated with each predictor in each of the regression models is given in the corresponding cell. The strongest simple linear predictor is shaded. Test scores are measured as percentages; the ISR span is measured as a list length.
