“…Previous behavior genetics studies have already found genetic influences on how often people use other evolutionarily novel technologies, including viewing television (Plomin, Corley, Defries, & Fulker, 1990;Rowe & Herstand, 1986;Sherry, 2001) and reading books (Friend et al, 2009;Harlaar et al, 2007;Martin et al, 2009) -just as pharmacogenomics studies have found substantial genetic influences on people's responsiveness to recently discovered psychiatric drugs for depression and schizophrenia (Daly, 2010). Also, personality traits known to be heritable influence usage patterns for every communication medium analyzed so far, including television, movies, music, art, books, email, online gaming, social networking sites, and chat rooms (Anolli et al, 2005;Chamorro-Premuzic et al, 2009;Finn, 1997;Hertel et al, 2008;Jeng & Teng, 2008;Kingston et al, 2009;Kraaykamp & van Eijck, 2005;Krcmar & Kean, 2005;Landers & Lounsbury, 2006;McManus & Furnham, Geoffrey Miller, Gu Zhu, Margaret J. Wright, Narelle K. Hansell, and Nicholas G. Martin 2006;Persegani et al, 2002;Ross et al, 2009;Sherry, 2001;Shim & Paul, 2007). Many of these heritable personality traits -especially extraversion, impulsivity, and neuroticism -also influence normal and addictive use of mobile phones (Arns, Van Luijtelaar, Sumich, Hamilton, & Gordon, 2007;Butt & Phillips, 2008;Ehrenberg et al, 2008).…”
