Comparison of direct attention to peripheral targets. Data from Experiment 4. (A) Mean sensitivity differences at each location for the differences obtained for white stimuli: Superior – Inferior directed attention (6 subjects). Positive values indicate Superior >Inferior, and negative values Inferior >Superior. (B) Illustration of the 5 pooling zones that replaced the 5 rings of earlier eccentricity analyses (Figs 5,6) in otherwise similar linear mixed effects models. (C) Results from the mixed effects models showed that only the white stimuli produced significant differences for the Superior and Inferior zones. The * mark the differences that are significant (p < 0.05). The symbols for the white and yellow stimuli are displaced slightly left and right to allow all the dots to be seen. The SE for the yellow data (not shown to reduce clutter) were almost identical to those of for the white stimuli. (D) Means of the sensitivity differences (±SE) for test regions straddling the vertical meridian. The position of the attentional targets is given by the black dots at ±10 degrees.
