Three experiments considered whether there are differences between overweight and normal weight subjects in time perception which represent the obese subjects' lack of internal responsiveness as well as heightened external reactivity in a noneating setting. In the first study, no time-relevant cues were provided, and overweight subjects were inaccurate in their temporal judgments and showed significantly higher group variability than did normals. In the second study, the effects of differential temporal information generated by interesting and boring cues was considered. The presentation of these time-relevant external cues reduced the judgment variability of the overweight subjects and influenced their perceived passage of time significantly more than normals. The third study examined the influence, on eating behavior, of differences in perceived passage of time as a consequence of manipulating cues for interest or boredom. When bored, overweight subjects perceived time to pass more slowly than did normals and thus ate sooner. Similarly, they delayed eating, judging time to have passed more quickly than it actually had, when they were attending to interesting cues. The implications of a generalized lack of internal sensitivity for a theory about the development and consequences of obesity are discussed.
三项实验探讨了超重和正常体重受试者在时间感知方面是否存在差异，这些差异体现了肥胖受试者在非进食环境中缺乏内部反应能力以及具有更高的外部反应性。在第一项研究中，未提供与时间相关的线索，超重受试者的时间判断不准确，且与正常体重受试者相比，其组内变异性显著更高。在第二项研究中，考虑了由有趣和无趣线索产生的不同时间信息的影响。这些与时间相关的外部线索的呈现降低了超重受试者的判断变异性，并且对他们感知到的时间流逝的影响比对正常体重受试者的影响要显著得多。第三项研究考察了由于操纵有趣或无趣线索而导致的感知时间流逝差异对进食行为的影响。当感到无聊时，超重受试者比正常体重受试者感觉时间过得更慢，因此进食更早。同样，当他们关注有趣的线索时，他们会延迟进食，认为时间过得比实际更快。本文讨论了普遍缺乏内部敏感性对肥胖发展及后果理论的影响。
