The Role of Visual Processing Speed in Reading Speed Development
Figure 5
Partial regression plots and sample regression model for regression VA span = age + C + K.
(Top) Partial regression plot for the effect of visual processing speed C on VA span, controlling for age. The residuals of the regression of VA span on VSTM capacity K and age are plotted against the residuals of the regression of visual processing speed C on VSTM capacity K and age. (Bottom) Partial regression plot for the effect of VSTM capacity K on VA span. The residuals of the regression of VA span on visual processing speed C and age are plotted against the residuals of the regression of VSTM capacity K on visual processing speed C and age. The solid lines represent the regression line and the shaded areas represent the regression lines' 95% confidence intervals.
