Non-verbal behaviour often provides one of the first opportunities to make socially relevant judgments. For example, gait has been shown to inadvertently signal information about personality and vulnerability. Although non-verbal cues such as gait appear to signal socially relevant information, researchers have identified distinct differences in the ability of observers to accurately perceive these cues. Based on this research, Study 1 examined the personalities and victimization histories of walkers in relation to their gait, and Study 2 explored individual differences in observer's perceptions of the walkers' personality and vulnerability. While victimization history was associated with the display of vulnerable gait cues in Study 1, this association was dependent on victimization type and the cognitive state of the walker. That is, when the walkers felt comfortable, those who had exclusively experienced sexual victimization displayed significantly more vulnerable gait cues than non-victims, while walkers who had exclusively experienced violent victimization did not. Conversely, when the walkers felt uncomfortable, no associations were identified between gait and victimization history. Further, no associations were identified between gait and personality. In Study 2, psychopathy was identified as the most salient predictor of accuracy in perceiving vulnerability to victimization.This association was also dependent on victimization type, where observers higher on psychopathy were significantly more accurate in perceiving vulnerability to violent, but not sexual victimization. While observers were not able to accurately perceive the walkers' personalities, there was a general tendency to view sexual victims as passive, while violent and non-victims were viewed as charismatic. Taken together, the results of the current study raise questions about the role gait plays in perceptions of vulnerability and personality among psychopathic observers.
PERCEPTIONS OF PERSONALITY AND VULNERABILITYiii Acknowledgements I would first like to acknowledge Dr. Adelle Forth. Without her support, knowledge, and inspiring passion for research, I would not be the graduate student I am today. Adelle has made my time at Carleton unforgettable, and I will never be able to thank her enough for everything she has done for me as a professor, supervisor, mentor, colleague, and friend.
