摘　　要：本研究探讨疼痛条件下时间目标对时距估计的影响。结果发现:疼痛条件下时距估计值小于非疼痛条件下时距估计值,疼痛条件下具体时间目标的时距估计值显著大于无目标的时距估计值。临床上给患者提供具体的时间目标或许有助于他们应对疼痛。Both duration estimation and pain have great significance for human survival. According to many researchers, duration esti mation is influenced by many factors, including experimental paradigms, estimation methods, and pain condition. The majority of the previous studies which examined the duration estimation under pain condition adopted only the retrospective paradigm and verbal report method. So, firstly, we would like to explore more paradigms and estimation methods under pain condition. Experiment 1 examined the effect of paradigms and estimation methods on time duration estimation under pain condition. 54 under graduates were required to put their hands in water and try to estimate the time duration （12 seconds）. A 2 （experimental paradigm, retrospective vs. prospective） x 2 （estimation method, verbal report vs. duplication） x 2 （water temperature, 3℃ vs. 31℃ ） design was used in Exp. 1. All subjects were administered with prospective experiment and then retrospective experiment. The results showed that there were significant main effect of water temperature, （F（1, 44） = 3.84, p =. 056） and paradigm （F（ 1,44） = 33.51, p 〈 0. 01 ）. Duration judgments were significantly shorter under pain condition than under normal condition and prospective judgments were longer than retrospective judgments. In Experiment 2, based on the evidence that subjects with certain endurance targets would underestimate the pain intensity, we want to investigate whether the endurance target would improve duration estimation under pain condition. 57 undergraduates were ran domly selectedin the experiment with a 2 （ experimental paradigm, retrospective vs. prospective） 2 （ estimation method, verbal report vs. duplication） 2 （endurance target, 3 minutes vs. no certain target） design. All subjects were required to put their hands in cold water （3℃）, and those in ＂3 minutes＂ group were told to try to persist 3 minutes, but the subjects in the other group were told to per sist a
