Classical deindividuation theory has been posited as a useful framework for
understanding certain cognitive and behavioral changes commonly seen in co
mputer-mediated communication (CMC). Participants in CMC discussion groups
were significantly more immersed in the discussion than face-to-face (FTF)
discussants, and tended not to perceive their team members as individuals,
providing evidence that the CMC users met the cognitive criteria for a stat
e of deindividuation. Nevertheless, CMC participants did not produce more n
egative behaviors than FTF participants, demonstrating that it is insuffici
ent to attribute negative behavior solely to a deindividuated state. These
results are discussed in light of classical deindividuation theory and are
contrasted with predictions from the more recent social identity/deindividu
ation model. (C) 1999 Elsevier Science Ltd. AII rights reserved.
