  • Title: Prolonged subjective duration near the hands: Effects of hand proximity on temporal reproduction.
    Author: Qi Y, Wang X, He X, Du F.
    Journal: Psychon Bull Rev; 2019 Aug; 26(4):1303-1309. PubMed ID: 31144134.
    Abstract:
    It has been reported that human visual perception and attention are altered when the hands are nearby. Previous studies indicate that placing hands near stimuli enhances a subject's temporal sensitivity. However, few researchers have investigated the effect of hand proximity on reproducing temporal duration. Moreover, the delayed attentional disengagement and enhanced magnocellular visual processing theories provide two distinct predictions of the hand proximity effect on reproduced duration. Delayed attentional disengagement near hands will cause prolonged reproductions, whereas enhanced magnocellular visual processing predicts more accurate reproduction in the peri-hand space. The current study is the first to show that a short temporal duration is reproduced for a longer period near hands than far from hands in the dual-responding-hand condition, and this hand-proximity effect is attenuated in the single-responding-hand condition. These findings together with two further studies suggest that reproducing a temporal duration is modulated by hand proximity through prolonged attentional switch.
