Eye-gaze Cueing Task
Mean RTs and error percentages are displayed in Table 2.
The ANCOVA conducted on the mean of RTs revealed a significant main effect of Validity (F1,40= 13.25; p< 0.001), with faster responses for valid trials. The main effect of Group was not significant (F1,39= 1.35; p= 0.252). The interaction Group by Validity was not significant (F<1; see fig. 3). After removing IQ as a covariate differences between groups were still not significant (Group effect: F1,40= 2.57; p= 0.117; Group by Validity interaction: F<1)
The ANCOVA conducted on error percentages revealed no significant effects: Group (F1,39= 1.18; p= 0.282), Validity (F1,40= 1.95; p= 0.17), Group by Validity (F1,40= 1.32; p= 0.257). These effects remained not significant.in the analyses without IQ as a covariate.
