Abstract

Incubation of craving is a phenomenon describing the intensification of craving for a reward over extended periods of abstinence from reinforcement. Animal models use instrumental markers of craving to reward cues to examine incubation, while human paradigms rely on subjective self-reports. Here, we characterize an animal-inspired, novel human paradigm that showed strong positive relationships between self-reports and instrumental markers of craving for favored palatable foods. Further, we found consistent nonlinear relationships with time since last consumption and self-reports, and preliminary patterns between time and instrumental responses. These findings provide a novel approach to establishing an animal-inspired human model of incubation.

将人类食物渴求潜伏期的自我报告和工具行为联系起来。
渴求潜伏是一种现象,描述的是在长时间缺乏强化的情况下,对奖赏的渴求会增强。动物模型使用渴求奖赏线索的工具性标记来研究潜伏期,而人类范例则依赖于主观的自我报告。在这里,我们描述了一个受动物启发的新型人类范例,该范例显示了自我报告与对所喜爱的美味食物的工具性渴求标记之间的密切正相关关系。此外,我们还发现了自上次消费后的时间与自我报告之间的一致非线性关系,以及时间与工具反应之间的初步模式。这些发现为建立受动物启发的人类潜伏模型提供了一种新方法。

期刊介绍: The neurobiology of learning and memory is entering a new interdisciplinary era. Advances in neuropsychology have identified regions of brain tissue that are critical for certain types of function. Electrophysiological techniques have revealed behavioral correlates of neuronal activity. Studies of synaptic plasticity suggest that some mechanisms of memory formation may resemble those of neural development. And molecular approaches have identified genes with patterns of expression that influence behavior. It is clear that future progress depends on interdisciplinary investigations. The current literature of learning and memory is large but fragmented. Until now, there has been no single journal devoted to this area of study and no dominant journal that demands attention by serious workers in the area, regardless of specialty. Learning & Memory provides a forum for these investigations in the form of research papers and review articles.
