It was hypothesized that the greater influence of external cues on obese than on normal individuals' eating behavior is a manifestation of a generalized sensitivity to external cues. Responsivity of nut consumption to the external cue of shells on the nuts and responsivity of judgment of verticality to the external cue of a tilted visual field were assessed for male and female, obese and normal-weight subjects. As predicted, both obese subjects' nut consumption and their judgments of verticality were more influenced by external cues than were those of normals. Females' judgments of verticality were more influenced by external cues than males' were, but the sex differences in eating behavior were not statistically significant. A significant correlation between the field dependence of subjects' eating behavior and their judgments of verticality suggests that a single cause may generate sensitivity to external cues in these two diverse situations.
据推测，外部线索对肥胖者饮食行为的影响比对正常个体更大，这是对外部线索普遍敏感的一种表现。针对男性和女性、肥胖和正常体重的受试者，评估了坚果食用量对坚果外壳这一外部线索的反应以及垂直性判断对倾斜视野这一外部线索的反应。正如预期的那样，肥胖受试者的坚果食用量和他们对垂直性的判断比正常人更受外部线索的影响。女性对垂直性的判断比男性更受外部线索的影响，但饮食行为的性别差异没有统计学意义。受试者饮食行为的场依存性与其垂直性判断之间存在显著相关性，这表明单一原因可能在这两种不同情况下产生对外部线索的敏感性。
