A disproportionate amount of research on impulsivity has focused on trait-related aspects rather than state fluctuations. As a result, the relationship between state impulsivity and moment-to-moment behaviour is unclear. Impulsivity is assumed to negatively affect self-control, but an alternative explanation, yet to be tested, could be that changes in state impulsivity and its homeostatic drivers influence the intensity of urges. We tested whether state impulsivity and hunger affected behaviour through a dual-process model, affecting both the experience of various urges, and self-control, using a smartphone-based experience sampling approach. We found that state impulsivity is associated with stronger urges, but we found no evidence of an association with diminished self-control. Being hungry amplifies urges across different types of urges, and both hunger and late hours are negatively related to the likelihood of controlling urges. These findings imply that the influence of hunger is not limited to the food domain, and provide new insight into the role of state impulsivity in daily life.

对冲动性的大量研究集中在与特质相关的方面，而不是状态波动。因此，状态冲动与瞬间行为之间的关系尚不清楚。冲动性被认为会对自我控制产生负面影响，但另一种尚待检验的解释可能是状态冲动性的变化及其稳态驱动因素会影响冲动的强度。我们使用基于智能手机的体验抽样方法通过双过程模型测试了状态冲动和饥饿是否影响行为，影响各种冲动的体验和自我控制。我们发现状态冲动与更强烈的冲动有关，但我们没有发现与自我控制能力下降有关的证据。饥饿会放大不同类型的冲动，饥饿和迟到都与控制冲动的可能性负相关。这些发现表明饥饿的影响不仅限于食物领域，并为国家冲动在日常生活中的作用提供了新的见解。
