Keyword欺骗行为 人体运动信息 非言语视觉线索 谎言识别
3. 综合考虑研究一与研究二的结果可发现,研究一中在欺骗与基线条件之间不存在差异的身体部位,即右手腕及手肘的运动信息,在研究二中与个体识别欺骗行为的正确率负相关。反之,研究一中在欺骗与基线条件之间存在差异的身体部位的运动信息(例如与躯干有较大关系的左右肩膀),在研究二中发现与个体识别欺骗行为的正确率正相关。根据以上的结果,本论文从人体运动信息表达及识别两方面的结果,验证了人体运动信息作为有效的非言语视觉欺骗线索的可能性。
Other AbstractDeceptive behavior is a common and frequently observed behavior in society because successful deceptive behavior have been observed to reward the individual with more resources, aid individuals escape punishments, as well as play a role in mediating balance and improvements in social relationships. As beneficial as it may be for the deceiving individual, most lies are disadvantageous to the receiver and may lead to serious consequences if the individual is not aware of the lie. As such, humans spend a lifetime learning to deceive others, simultaneously they learn how to detect deception in order to prevent themselves from becoming a victim of deception. Since ancient times, researchers and scholars alike have sought to reveal nonverbal cues of deception that can effectively aid individuals in veracity judgments. Despite centuries of research spent on uncovering nonverbal cues of deception, recent extensive meta-analyses on deception research from the past century revealed that half of the nonverbal cues thought to be linked to deception are in fact unrelated to deception.
The current study extensively reviewed research studies on the nonverbal cues of deception from the past century along with its problems and flaws, and noticed at the core of previous deception research exists a very critical problem regarding precise quantification of behaviors and obtainment of objective measures of deceptive behavior. Accounting for this issue, the current study propose to use motion capture technology, which has been known to accurately and precisely record human bodily movements, to resolve issues regarding quantification of behaviors that occur during deception. The study aims to answer an age old question and investigate whether at a kinematic level representation of behavior, differences between deceptive and baseline behaviors exist, and whether these differences are in anyway related to psychological factors that are related to deception. The current research is organized into two sections. The first section aims to investigate whether individuals kinematic information differ when the individual attempts to deceive compared to the individual's behavior under baseline conditions.
Findings obtained in the first section of our research are then used to further evaluate whether individuals' kinematic information serve as a good nonverbal cue of deception. The second section of the research aims to uncover the nonverbal cues and bodily cues that individuals rely upon in deception detection tasks. Utilizing eye-tracking technology, we aim to capture individual's gaze pattern and investigate which bodily cues individuals rely upon to form veracity judgments. Through which we hope to uncover useful nonverbal cues of deception that may help to improve individuals accuracy in deception detection.
Listed below are some of the main findings in the current research: 1. We found that individuals’ whole body kinematic information in the deceptive condition (not including the following joints: left hip, right wrist, and right elbow) differed from individuals kinematic information in the baseline condition. Specifically, we observed that individuals with the intent to deceive moved slower and moved less than baseline conditions.
2. Correlation analyses revealed that individuals’ fixation duration on the hands were negatively correlated to individuals accuracy of veracity judgments. In contrast, we found that fixation count and fixation duration on the body were positively correlated to individuals accuracy of veracity judgment.
3. Reviewing the results from the first and second section of the research, we observed a fairly consistent result across both research. In the first section, we observed that the actors' hand movement and hand kinematic information did not differ significantly between the deceptive and baseline condition. This result suggest that hand kinematic information may not be useful in differentiating deceptive behavior from baseline behavior. Supporting this proposition was the correlation analyses result that indicated a negative correlation between individual's accuracy in veracity
judgment and individuals' fixation duration on the actor's hand. The same result could be observed for body cues as well, except that body cues were positively correlated to accuracy in veracity judgments. According to results from both deception expression and recognition tasks, we may conclude with certain confidence that individuals' bodily kinematic information (specifically an individual’s torso kinematic information) could serve as an effective nonverbal visual cue of deception. The current study utilized both motion capture technology and eye-tracking technology to conduct an insightful and exploratory study on whether individuals bodily expression of kinematic information differed in deceptive and baseline conditions; furthermore investigated its relationship to deception. Our findings suggest body kinematic information may serve as an effective nonverbal visual cue of deception, extending current understandings of nonverbal cues to deception.
