Selective processing of appetitive cues was investigated among food-deprived subjects and restrained eaters using the modified Stroop.
Thirty-two university students (25 females, 7 males) were randomly assigned to a 6-hr food deprivation (FD) or a no food deprivation (NFD) condition. Subjects were also divided into three restrained eating groups-high (HR), moderate (MR), and low (LR)-according to Restraint Scale scores. Subjects color named sets of food, alcohol, and leisure control words. Stroop color-naming latencies were submitted to 2 x 3 (Food Deprivation Condition x Word Type) and 3 x 3 (Restrained Eating Group x Word Type) repeated measures analyses of variance (ANOVAs).
Food deprivation failed to produce longer latencies for food or alcohol words relative to control words. However, HR status was associated with significantly longer latencies for both food and alcohol, relative to control, words.
Chronic dietary restraint but not short-term food deprivation was associated with selective processing of appetitive cues. The results have implications for understanding food preoccupation and risk for alcohol abuse in restrained eaters.
使用改良的斯特鲁普任务，对食物匮乏者和节食者中对食欲线索的选择性加工进行研究。
32名大学生（25名女性，7名男性）被随机分配到6小时食物剥夺（FD）组或无食物剥夺（NFD）组。根据节食量表得分，受试者还被分为三个节食组——高（HR）、中（MR）和低（LR）。受试者对食物、酒精和休闲控制词进行颜色命名。将斯特鲁普颜色命名潜伏期提交给2×3（食物剥夺条件×词类型）和3×3（节食组×词类型）重复测量方差分析（ANOVA）。
相对于控制词，食物剥夺并未使食物或酒精词的潜伏期延长。然而，相对于控制词，HR状态与食物和酒精词的潜伏期显著延长相关。
长期节食而非短期食物剥夺与对食欲线索的选择性加工有关。这些结果对于理解节食者对食物的过度关注和酒精滥用风险具有启示意义。
