The study investigated the specificity of visuo-spatial working memory-based techniques as a means to reduce chocolate cravings. Twenty-four self-identified chocolate cravers and 24 non-cravers formed and maintained images of chocolate-containing foods elicited by pictures, while performing a visuo-spatial task (loading the visuo-spatial sketch pad) or an auditory task (loading the phonological loop). Vividness and craving intensity were rated for each image. Concurrent visuo-spatial processing was found to render chocolate images significantly less vivid and cravings less intense compared to concurrent verbal processing, for both cravers and non-cravers. Chocolate cravers did, however, report higher levels of chocolate craving and intake than non-cravers. It was concluded that visuo-spatial tasks provide an effective craving reduction mechanism for the management of chocolate cravings. Such techniques may be particularly useful in populations for whom eating problems are triggered by chocolate craving.
该研究调查了基于视觉空间工作记忆的技术作为减少巧克力渴望的一种手段的特异性。24名自我认定的巧克力渴望者和24名非渴望者在执行视觉空间任务（加载视觉空间画板）或听觉任务（加载语音回路）时，形成并维持由图片引发的含巧克力食物的图像。对每个图像的生动程度和渴望强度进行评分。结果发现，与同时进行言语处理相比，对于渴望者和非渴望者来说，同时进行视觉空间处理会使巧克力图像的生动程度显著降低，渴望程度也减弱。然而，巧克力渴望者报告的巧克力渴望程度和摄入量确实高于非渴望者。研究得出结论，视觉空间任务为控制巧克力渴望提供了一种有效的减少渴望机制。此类技术对于因巧克力渴望引发饮食问题的人群可能特别有用。
