“…Consistent with previous studies using the measure of likelihood of purchase to quantify demand for commodities (e.g., Roma et al, 2016), previous research has also documented that greater demand for social reinforcers is associated with various forms of problematic mobile phone use such as texting while driving (Hayashi, Friedel, et al, 2019a, 2019b), text-message dependency (Hayashi, Friedel, et al, 2019b;Hayashi & Blessington, 2021), inclass media multitasking (Hayashi, Friedel, et al, 2019b;Toyama & Hayashi, 2023a), and texting while walking (Hayashi, Friedel, et al, 2019b). Additionally, with respect to demand for general Internet/smartphone access (which can include various nonsocial activities, such as online gaming and gambling), previous studies have shown that greater demand is associated with problematic mobile phone use (Acuff et al, 2022) and higher frequency of text messaging (O'Donnell & Epstein, 2019).…”
