Low self-control capacity is associated with immediate responses to smartphone signals

The ubiquitous use of smartphones has not only led to unprecedented levels of connectivity, but also raised the question about potentially problematic side effects such as phone-use while driving or phone caused inattention in work or private settings. This poses the question about psychological mechanisms underlying this potentially self-damaging use. The present research addresses this question by showing how heterogeneity in people's self-control capacity explains behavioral differences in smartphone use. Specifically, we show that self-control capacity can be used to estimate whether a person immediately responds to a smartphone signal she receives. Thus, our research helps to identify personal characteristics that lead to a better understanding of problematic smartphone use and can potentially help to design appropriate protective mechanisms or interventions that target self-control capacity.
