From: Blue-light background impairs visual exogenous attention shift
(A) Background light spectra used in Experiment 4. The spectra of low and high ipRGCs stimulating background lights are plotted as a function of wavelength (x-axis) in radiant power (y-axis). (B) Attention shift latencies in different cue conditions under low and high ipRGCs stimulating background lights in Experiment 4. The two ends of grey lines connecting two boxplots indicate the average latencies of each participant under the low and high ipRGCs stimulating lights. The contrast-contrast interaction indicated that the ipRGCs stimulation accelerated both the exogenous and endogenous attention shifts. The symbol* indicates that the ipRGCs effect between two groups of conditions, one is the baseline condition, and the other is the exogenous-cue and endogenous-cue conditions, differ significantly (p < .05).
