This study examines the effect of 3D virtual worlds on an individual’s communication experience in comparison with Face-to-Face communications (FtFCs). Using 2 × 2 posttest only group design where subjects were asked to discuss over a given topic. This study investigated whether individuals’ different personality characteristics (i.e. shyness) influence communication experiences (i.e. communication apprehension). The data suggest that shy individuals felt less of communication apprehension during the discussion conducted online than FtFC. On the other hand, FtFC turned out to be more effective in influencing individuals’ intention to change behavior compared to virtual worlds. The results suggest that lack of visual/auditory cues in virtual reality is the major factor that influenced the outcome.
