Centre-of-Gravity Fixations in Visual Search: When Looking at Nothing Helps to Find Something
Figure 2
Effects of CoG fixations on search performance (RT), Experiment 1. Mean search times as a function of the proportion of void fixations in Experiment 1, depicted separately for each blocked condition (wide, narrow, and time-limited). Larger proportions of central void fixations were associated with shorter RT, both on target absent trials (black squares) and target present trials (grey triangles). Error bars depict 1 SEM and may be smaller than the plotting symbol.
