Centre-of-Gravity Fixations in Visual Search: When Looking at Nothing Helps to Find Something
Figure 6
Effects of COG fixations on search performance (RT), Experiment 2. Mean individual search times as a function of the proportion of fixations into a void region, depicted separately for the free viewing condition (FreeV; black diamonds) and the 4 different restricted viewing conditions (W = window, with number specifying the size of the viewable area in pixels). As in Experiment 1, a higher proportion of void fixations is associated with shorter RT, both on target present trials (a) and target absent trials (b).
