Table 7.

Model fits and the results of nested model F-tests for the analysis of the fMRI responses in area V2 from Buracas & Boynton (2006). The combination of attention parameters allowed to vary are shown in the first column, along with the sums of squared errors and percentage of variance accounted for. Additional columns show nested model F-tests for fits when parameters are added to each model.
