Preloaded and nonpreloaded dieters (restrained eaters) and nondieters (unrestrained eaters) completed a modified version of the Stroop task to measure selective biases in cognitive processing. In two separate studies, a milkshake preload led to increased cognitive interference for body shape words, especially for restrained eaters. There were no differences between restrained and unrestrained eaters in Stroop interference for either common or forbidden food words, whether subjects were preloaded or not. Taken together, these results indicate that chronic dieting is associated with selective processing of body shape words.
预先进食和未预先进食的节食者（克制饮食者）以及非节食者（非克制饮食者）完成了一项经过修改的斯特鲁普任务，以测量认知加工中的选择性偏差。在两项独立研究中，一杯奶昔预先进食导致对体型词汇的认知干扰增加，尤其是对克制饮食者而言。对于普通或禁食食物词汇的斯特鲁普干扰，无论受试者是否预先进食，克制饮食者和非克制饮食者之间均无差异。综合来看，这些结果表明长期节食与体型词汇的选择性加工有关。
