Abstract
Emotion colors our sense of time. The present study investigated whether emotional stimuli without awareness affected time perception of coincident visual stimuli. Through a mirror stereoscope, the observers were presented the emotional stimuli (positive, negative, and neutral photographs) to one eye and continuously swapped Mondrian stimuli to the other eye. The continuous flashes of the Mondrian stimuli rendered the emotional stimuli invisible. A white rectangular frame surrounding the Mondrian stimuli was presented for 2700 msec as a target. The observers reproduced the duration of the target. Consequently, the reproduced duration of the target was significantly longer with the negative than positive stimuli. The results suggest that unconscious emotional stimuli influences time perception.
