Abstract
The aim of this study was to investigate the effect of psychosensory pupil size responses and color on detection performance in a light and dark environment, to examine a possible shift from rod-dominated vision to cone-dominated vision. A total of 55 participants, of which 43 participants participated in the light condition (31 females, 12 males, Mage = 20.51, SD = 2.21) and 50 in the dark condition (35 female, 15 males, Mage = 20.52, SD = 2.23), took part in this experiment. We measured the pupil size prior to the presentation of a stimulus during a cognitive task. We found that the psychosensory pupil size in the detection task has a significant effect on detection accuracy, where big pupil size resulted in better detection accuracy. In addition, we found an effect of color on the detection of faint stimuli, where red targets resulted in a higher detection accuracy than blue targets, with this difference reaching statistical significance only in the lighting condition. No interaction effect was found between pupil size and color on detection accuracy. Our findings suggest a complex interaction between pupil dynamics and color sensitivity, warranting further investigation into the underlying mechanisms and conditions that influence visual processing and perception.
