“…Considering that the preference‐reversal explanation for problematic mobile phone use aligns with the conceptual framework of the reinforcer‐pathology model, it is vital to evaluate what empirical evidence actually supports the framework. Previous research has documented that steeper rates of delay discounting for hypothetical social reinforcers were significantly associated with various types of mobile‐phone‐related problems, such as texting while driving (Foreman et al, 2019; Hayashi et al, 2016, 2018; Hayashi, Foreman, et al, 2019), in‐class media multitasking (Hayashi & Blessington, 2018; Toyama & Hayashi, 2023b), and text‐message dependency (Ferraro & Weatherly, 2016; Reed, Becirevic, et al, 2016). In particular, delay‐discounting rates of social reinforcers that are associated with text messaging are well described by the hyperbolic/hyperboloid functions (e.g., Hayashi et al, 2016), supporting the preference‐reversal account of problematic mobile phone use.…”
