The identification of lie detection in verbal and nonverbal communication
The aim of this study was to investigate lie detection and truth telling in verbal and nonverbal cues. This was done using three groups (whole body, face and audio). Participants were assigned to a group and watched a video clip. This was to detect deception in verbal and nonverbal cues.Finally, participants then answered a questionnaire on the video clip.
This study aimed to investigate if there is a difference in people’s accuracy in detecting lies and truths based on verbal and/ or nonverbal cues. Forty-five participants were split into three groups. Each group was exposed to one of three different modes of viewing (whole body, face, audio) a person provide a brief biography about themselves. Afterwards, participants responded to a questionnaire which asked them to indicate whether statements from the biography were lies or truths.
Three between groups one-way analysis of variances (ANOVA) were used to analyse the data. The findings suggest that there was no significant difference for participants’ on their accuracy in detecting a lie or truth based on the mode of viewing. In addition, there was no significant difference for participants on their accuracy in detecting a correct response based on the mode of viewing. Patterns in the data, while not significant, suggest that the whole face and body modes of viewing showed the best statistical probability for detecting a lie.
