Thank you very much for your guidance and valuable suggestions. We are very grateful for your comments, which are very helpful for us to sort out the structure and motivation of the article.
1. The concept of 'true emotional expression' pertains to the congruence between an individual's outward emotional display and their internal affective state. Our emotion induction procedure establishes a baseline for emotional responses, which is crucial for comparison with the emotional responses observed during the deception experiment. Experimental results have indicated that emotional features significantly contribute to fraud detection tasks.
2. In this study, we present a comprehensive multimodal deception detection dataset, encompassing visual, audio, and textual data, as well as personality and emotional features. This dataset, being the largest of its kind, offers a unique opportunity to investigate how personality and emotional traits can enhance deception detection. Our work not only lays the foundation for future research in emotion computing but also suggests potential methods to improve emotion recognition by integrating personality insights and enhancing personality recognition performance with emotional cues. Through extensive experiments, we have preliminarily demonstrated the value of integrating personality and emotional traits in deception detection tasks. While our application of machine learning methods may not have achieved the desired level of advancement, we believe that deception detection is inherently challenging, with various machine learning methods showing limited performance. This suggests a need for the research community to further explore the features and methods within this dataset. Thus, we propose a simple machine learning method as a baseline for our analysis. In the revised manuscript, we have conducted a more in-depth analysis of the impact of machine learning on new datasets, including remaining challenges and insights into the limitations of current architectures, and how this dataset can contribute to advancing research in this field.
3. In the updated manuscript, we have included information on the public availability of existing datasets.
4. Building upon the six emotions covered by the Chinese Emotional Video System (CEVS)—happiness, sadness, anger, fear, disgust, and neutrality—we have added relaxation and surprise to our dataset. Relaxation serves as an emotional baseline, allowing for the comparison of other emotional states. Deviations from a relaxed state during specific questions or situations may indicate deception, as inconsistent relaxation levels could suggest an attempt to deceive. Surprise, a spontaneous and difficult-to-fake emotion, can indicate truthfulness or deception; a genuine surprise response to an unexpected question or accusation may suggest unpreparedness and honesty, while a lack of surprise may indicate a prepared deceptive response.
5. Our experiments were conducted at least five times with randomly selected samples, and the average results were taken to ensure statistical significance.
6. Regarding ethical issues, we ensured that all experimental procedures were explained to the subjects, who provided explicit consent for the recording and publication of their conversation and video data in scientific conferences or journals. Our data collection and dissemination adhere to the principle of informed consent and comply with relevant laws, regulations, and ethical review requirements, all approved by our institution's Human Subjects Institutional Review Board. We have implemented privacy protection measures, did not publish any personally identifiable information, and restricted dataset access to users who agree to use it solely for scientific research. The release of our deception dataset aligns with international standards and industry best practices, positively impacting scientific research, technological progress, and public safety. We have added a new section in the revised manuscript to address these ethical considerations, ensuring a comprehensive and responsible approach to handling the deception detection dataset.
7. We have thoroughly revised the manuscript to improve the quality of writing and address all language issues, including specific errors such as "role.Although," "new multi-modal deception dataset," and reference formatting, as pointed out by the reviewers.
