Mobile electronic devices are playing an increasingly pervasive role in our daily activities. Yet, there has been very little empirical research investigating how mobile technology habits might relate to individual differences in cognition and affect. The research presented in this paper provides evidence that heavier investment in mobile devices is correlated with a relatively weaker tendency to delay gratification (as measured by a delay discounting task) and a greater inclination toward impulsive behavior (i.e., weaker impulse control, assessed behaviorally and through self-report) but is not related to individual differences in sensitivity to reward. Analyses further demonstrated that individual variation in impulse control mediates the relationship between mobile technology usage and delay of gratification. Although based on correlational results, these findings lend some backing to concerns that increased use of portable electronic devices could have negative impacts on impulse control and the ability to appropriately valuate delayed rewards.
移动电子设备在我们的日常活动中发挥着越来越普遍的作用。然而，很少有实证研究调查移动技术习惯与认知和情感方面的个体差异之间可能存在怎样的关联。本文所呈现的研究提供了证据，表明在移动设备上投入更多与延迟满足的倾向相对较弱（通过延迟折扣任务衡量）以及更倾向于冲动行为（即冲动控制较弱，通过行为和自我报告评估）相关，但与对奖励的敏感度的个体差异无关。分析进一步表明，冲动控制的个体差异介导了移动技术使用与延迟满足之间的关系。尽管基于相关结果，但这些发现为以下担忧提供了一些支持，即便携式电子设备使用的增加可能对冲动控制以及正确评估延迟奖励的能力产生负面影响。
