The Emotional Arousal Mechanism of Hue's Influence on Temporal Duration Perception

Behavioral results indicated that participants' p(long) values under red stimulation were significantly greater than those under blue, suggesting that participants overestimate temporal duration when exposed to red stimuli.

ERP results revealed that the amplitude of the N1 wave induced in the parietal-occipital region was significantly larger under red stimulation compared to blue. However, there was no significant difference in the amplitude of the P2 wave induced in the frontal region between the two hues. Therefore, individuals' estimation of temporal duration under different hues was influenced by emotional physiological arousal.
