The role of arousal in the estimation of time-to-collision of threatening stimuli.
The accurate estimation of time-to-collision (TTC) is essential for the survival of organisms. Previous studies have revealed that the emotional properties of approaching stimuli can influence the estimation of TTC, indicating that approaching threatening stimuli are perceived to collide with the observers earlier than they actually do, and earlier than non-threatening stimuli. However, not only are threatening stimuli more negative in valence, but they also have higher arousal compared to non-threatening stimuli. Up to now, the effect of arousal on TTC estimation remains unclear. In addition, inconsistent findings may result from the different experimental settings employed in previous studies. To investigate whether the underestimation of TTC is attributed to threat or high arousal, three experiments with the same settings were conducted. In Experiment 1, the underestimation of TTC estimation of threatening stimuli was replicated when arousal was not controlled, in comparison to non-threatening stimuli. In Experiments 2 and 3, the underestimation effect of threatening stimuli disappeared when compared to positive stimuli with similar arousal. These findings suggest that being threatening alone is not sufficient to explain the underestimation effect, and arousal also plays a significant role in the TTC estimation of approaching stimuli. Further studies are required to validate the effect of arousal on TTC estimation, as no difference was observed in Experiment 3 between the estimated TTC of high and low arousal stimuli.
期刊介绍:
PsyCh Journal, China''s first international psychology journal, publishes peer‑reviewed research articles, research reports and integrated research reviews spanning the entire spectrum of scientific psychology and its applications. PsyCh Journal is the flagship journal of the Institute of Psychology, Chinese Academy of Sciences – the only national psychology research institute in China – and reflects the high research standards of the nation. Launched in 2012, PsyCh Journal is devoted to the publication of advanced research exploring basic mechanisms of the human mind and behavior, and delivering scientific knowledge to enhance understanding of culture and society. Towards that broader goal, the Journal will provide a forum for academic exchange and a “knowledge bridge” between China and the World by showcasing high-quality, cutting-edge research related to the science and practice of psychology both within and outside of China. PsyCh Journal features original articles of both empirical and theoretical research in scientific psychology and interdisciplinary sciences, across all levels, from molecular, cellular and system, to individual, group and society. The Journal also publishes evaluative and integrative review papers on any significant research contribution in any area of scientific psychology
