The study investigated the relative effectiveness of thought suppression and the working memory-based method of dynamic visual noise as techniques for reducing food cravings. Twenty dieting women on the weight-loss programme prescribed by weight watchers and 20 non-dieting controls formed images of their most craved food and then suppressed thoughts of the food or watched a flickering pattern of black and white dots (dynamic visual noise). Both thought suppression and dynamic visual noise reduced cravings for weight watchers and non-dieters. However, their relative effectiveness varied according to participant dieting status. Specifically, while both techniques reduced cravings equally well for non-dieters, dynamic visual noise was clearly the more effective technique for weight watchers. Thus, dynamic visual noise may provide a useful tool for controlling problematic cravings in clinically overweight or obese individuals who are actively trying to lose weight.
该研究调查了思维抑制和基于工作记忆的动态视觉噪声方法作为减少食物渴望的技术的相对有效性。20名参加慧俪轻体规定的减肥计划的节食女性和20名非节食对照者想象出她们最渴望的食物，然后抑制对该食物的想法，或者观看黑白点闪烁图案（动态视觉噪声）。思维抑制和动态视觉噪声都减少了慧俪轻体参与者和非节食者的渴望。然而，它们的相对有效性因参与者的节食状态而异。具体而言，虽然这两种技术对非节食者减少渴望的效果相同，但动态视觉噪声对慧俪轻体参与者显然是更有效的技术。因此，动态视觉噪声可能为积极尝试减肥的临床超重或肥胖个体控制有问题的渴望提供一种有用的工具。
