Table 2. Probability values for the F-test.

A) Pestilli, Viera & Carrasco (2007) the results for exogenous attention in this study are well explained by a response-gain model (green-shaded areas; contrast-gain wins over the mixed, two-parameters, model). Except for the valid-cue condition in observer S3, where the mixed model (two parameters model) is needed. B) Ling & Carrasco (2006) the results for endogenous attention (Endo) in every observer are well described by a contrast-gain model (green-shaded are cell; contrast-gain wins over the mixed, two-parameters, model), but not by a response-gain model (orange-shaded cells; the mixed, two-parameters model, wins over response-gain). The results for exogenous attention (Exo) in every observer are well described by a response-gain model (green-shaded cells; response-gain wins over the mixed, two-parameters, model), but not by a contrast-gain model (orange-shaded cells; the mixed, two-parameters model, wins over contrast-gain).
