With the advent of the Internet and the increasingly common use of computers to communicate with others (Christopherson 2007), computer-mediated communication (CMC) and social media have become indispensable to study psychological context in a social way. Regarding CMC, it has been postulated that the absence of social feedback and information about the social context could lead to uninhibited behavior, as these gaps may not yet have been replaced by shared norms for conveying or interpreting the social meaning of communication (Siegel, Dubrovsky, Kiesler & McGuire 1986). We propose that the anonymity of CMC allows individuals who otherwise engage in normatively prosocial behaviors to engage in antisocial and antinormative behaviors. This occurs through processes of deindividuation and depersonalization. Furthermore, this behavior will be influenced by the salient norm; antinormative and antisocial behavior will occur when an antisocial norm is salient, while prosocial behavior will be involved when a prosocial norm is salient. Classic deindividuation theory, such as that proposed by Festinger, Pepitone, and Newcomb in 1952 and further elaborated by Zimbardo in 1969, involves an examination of the effects of in-group anonymity, in which individuals are not "seen or paid attention to as individuals" (Festinger et al., 1952, p. 382). Deindividuation theory proposes that when an individual is submerged and anonymous while part of a group, a state of reduced self-awareness and loss of individuality may result, resulting in transgressions of general social norms (Postmes & Spears, 1998). This state of deindividuation can result in antinormative and antisocial behavior towards others, as they are unidentified or...... half of paper ......27– 459.Spears, R., Postmes, T., Lea, M., & Watt, S.
