This study aimed to extend recent experimental work on the efficacy of visuo-spatial working memory-based techniques for reducing food cravings by adopting a more naturalistic methodology. Fifty undergraduate women formed images of their favorite foods while performing a visuo-spatial task across six successive trials. Vividness and craving intensity were rated for each food image. Concurrent visuo-spatial processing reduced the vividness of, and craving reactivity to, personally relevant food images. Forehead tracking, a novel self-administered task, proved to be as effective in reducing vividness and craving ratings as the established visuo-spatial working memory laboratory tasks of eye movements, dynamic visual noise, and spatial tapping, and thus presents a simple, accessible technique potentially applicable in the home environment. All four tasks maintained their reducing effect over multiple trials. Individual differences in imaging ability and habitual food craving did not impact upon their effectiveness, indicating that visuo-spatial tasks can be successfully used to reduce food cravings across a range of people.
本研究旨在采用更自然主义的方法，扩展近期关于基于视觉空间工作记忆的技术对减少食物渴望的功效的实验工作。五十名本科女性在连续六次试验中执行视觉空间任务时，形成她们最喜欢食物的图像。对每个食物图像的生动程度和渴望强度进行评分。同时进行的视觉空间处理降低了与个人相关食物图像的生动程度以及对其的渴望反应。前额追踪，一项新颖的自我管理任务，被证明在降低生动程度和渴望评分方面与既定的视觉空间工作记忆实验室任务（眼动、动态视觉噪声和空间敲击）一样有效，因此呈现出一种简单、可及的技术，有可能在家用环境中应用。所有四项任务在多次试验中都保持了其减少效果。成像能力和习惯性食物渴望的个体差异并未影响它们的有效性，这表明视觉空间任务可以成功地用于减少各类人群的食物渴望。
