Performance and perception results. (A,D) Represent the task × condition interactions. Bars represent the mean RTs (A) and the mean subjective ratings (D) in T (empty), VTNear (solid), and VTFar (striped) conditions in the unilateral (grey) and in the bilateral (yellow) task. Error bars indicate standard error of the mean (SEM). Dots represent individual participants. *p < 0.05; **p < 0.01; ***p < 0.001; ****p < 0.0001. (B,C,E,F) Represent the mean RTs (B,C) and the mean subjective ratings (E,F) of each one of the 20 tested participants, in each condition, and separately for each task [unilateral: (B,E); bilateral: (C,F)]. Dots represent mean individual values in the T condition, squares represent mean individual values in the VTNear condition and triangles represent mean individual values in the VTFar condition. Error bars indicate standard error of the mean (SEM). Note that, while in the unilateral task the majority of participants show faster RTs and higher ratings in the VTNear as compared to both VTFar and T, in the bilateral task they show significantly slower RTs and lower ratings in T as compared to both VTFar and VTNear.
