吸烟对时距知觉的影响

The Effect of Smoking on Interval Perception

吸烟对人们的危害是多方面的,本研究采用时间二分法范式,分别选取了秒下、秒上各7个时距,以探索吸烟对时距知觉的影响。结果发现:1) 吸烟组与非吸烟组的主观相等点并不显著;2) 被试秒下的时距反应时显著快于秒上;3) 相较于不吸烟,吸烟可以降低韦伯比例。结论表明:1) 吸烟并没有延长或缩短时距知觉;2) 秒下时距是自动加工;3) 吸烟提高了时距知觉的敏感性,可能是在短期内提升了反应准备和反应执行的结果。

The harm of smoking on people is multifaceted. This study adopts the time dichotomy paradigm, and selects 7-time intervals under and above the second respectively, to explore the influence of smoking on time interval perception. The results showed that: 1) the subjective equivalence points of the smoking group and the non-smoking group were not significant;2) the response time was significantly faster than that in seconds;3) compared with non-smokers, smoking can reduce the proportion of Webber. The results showed that: 1) smoking does not affect temporal perception;2) second-time interval is automatic processing;3) smoking improves the sensitivity of time interval perception, which may be the result of short-term improvement of response preparation and response execution.
