Less vigilant in the mobile era? A comparison of information processing on mobile phones and personal computers

Do people process information differently on mobile phones compared to computers? We investigate this question by conducting two online field experiments. We randomly assigned participants to use their mobile phones or personal computers (PCs) to process different kinds of information. Study 1 ( N = 116) discovered that participants using mobile phones process emails more efficiently (i.e., spend less time) than those using PCs. Study 2 ( N = 241) extended this to online deceptive content and found that individuals using mobile phones, especially habitual users, are more efficient, but engage in less information processing, are less attentive and less vigilant about misinformation, compared to those using PCs. However, the latter are more likely to succumb to phishing emails by clicking on malicious links. We discuss theoretical implications for information processing across media devices and practical implications for combating misinformation and cybersecurity attacks.
