A 2 x 2 between-subjects study was conducted to investigate thinking mode (unconscious thought, conscious thought) and stimuli complexity (high, low) on lie detection. One hundred and thirty five undergraduate students either watched audio-visual or listened to audio mediums and either engaged or not engage in a deliberate thinking before they were required to judge the veracity of the four subjects presented in the video. In addition to the effects of thinking mode and stimuli complexity on lie detection, it was predicted that those in unconscious thought and high stimuli complexity condition, and those in conscious thought and low stimuli complexity condition would be more accurate in detecting lies than the other two conditions. Although graphical results showed favourable outcome; statistically however, suggested that the hypotheses were not supported. Despite of that, this study provides an insight to lie detection across cultures and the theoretical framework used in this study.
