Four experiments tested responsiveness to external and sensory stimuli in female human subjects who differed in degree of overweight and in age of onset of their obesity. The effects of weight loss upon external responsiveness were assessed by testing subjects before and after weight reduction in order to determine the role of energy deficit and deprivation in mediating heightened responsiveness to external cues. There was no significant positive correlation between degree of overweight and degree of external responsiveness. In general, the age of onset of the obesity was also not a relevant factor in the degree of externality. Weight loss did not change responses to visual and cognitive cue salience manipulations in measures of feeding, emotionality, time perception, and short-term recall, whereas responsiveness to variations in palatability increased following weight reduction. While external cue responsiveness does not appear to result from adiposity per se or from deprivation, responsiveness to taste stimuli may reflect these parameters. The role of external and sensory cues in the development and maintenance of obesity is discussed.
四项实验测试了超重程度和肥胖发病年龄不同的女性人类受试者对外部和感官刺激的反应。通过在减肥前后对受试者进行测试来评估体重减轻对外部反应的影响，以确定能量不足和匮乏在介导对外部线索反应增强中的作用。超重程度与外部反应程度之间没有显著的正相关。一般来说，肥胖的发病年龄在外部性程度方面也不是一个相关因素。体重减轻并没有改变在进食、情绪、时间感知和短期记忆测量中对视觉和认知线索显著性操纵的反应，而减肥后对适口性变化的反应性增加。虽然外部线索反应性似乎不是由肥胖本身或匮乏导致的，但对味觉刺激的反应性可能反映了这些参数。讨论了外部和感官线索在肥胖发展和维持中的作用。
