Table 1. Linear mixed models fitting measures of extrafoveal and foveal processing for visual search data from three experiments: Means (b), standard errors (SE), and test statistics (t-values) for fixed effects.

Experiment 1 Experiment 2: vis absent Experiment 2: vis present Experiment 3: template Experiment 3: accessory

Note. Non-significant coefficients are set in bold (|t| < 1.96). Sem stands for semantically related objects and vis for visually related objects. The average was taken of the unrelated objects (denoted as u), except for the “visual absent” condition in Experiment 2 where the data is being displayed for each unrelated object separately (u1 and u2).
