99 Predictive factors of public anxiety under the outbreak of COVID-19
ZHEN Rui,ZHOU Xiao
The aim of this study was to examine the prevalence and predictors of public anxiety under the outbreak of the 2019 coronavirus disease (COVID-19). Self-reported questionnaires were used to investigate 1050 people the during COVID-19 outbreak, assessing their COVID-19 epidemic experiences, the time and valence of media exposure to COVID-19-related information, risk perception of this disease, and anxiety. The results found that the prevalence of public anxiety reached 18.0%, and the prevalence had no significant differences in gender, age, educational level, marital status, or monthly income. In addition, this study found that the more experiences of COVID-19-related events, the longer media exposure time of COVID-19- related information, especially negative information, and the severer perception of COVID-19, the greater probability of anxiety people had. In contrast, exposure to positive information about COVID-19, being familiar with COVID-19, and perception of COVID-19 as controllable were helpful to reduce the probability of anxiety. These findings indicate that COVID-19 epidemic experiences, the time and valence of media exposure to COVID-19-related information, and risk perception of this disease are important predictors of public anxiety.

108 User-centered design (V): From automation to the autonomy and autonomous vehicles in the intelligence era
XU Wei
This paper reviews the previous human factors research on human-automated interaction, human-autonomy interaction, and human-machine teaming. It also differentiates the characteristics of automation and autonomy from a human factors perspective. A conceptual model of the relationship among autonomy, automation, and human intervention is proposed to represent the human factors problem space of autonomy.The human factors community needs to re-cast its view of the human–machine collaborative relationship (human-machine teaming) driven by autonomous technology and re-assess the applicability of current human factors theories and methods. The paper also analyzes the human factors issues in the current development of autonomous vehicles.Human factors professionals should proactively engage in the development of autonomous vehicles, provide disciplinary support, and offer complete human factors solutions.

129 Change Blindness of Drivers in Traffic Scene and Its Implications
ZHAO Ao-xue, ZHUANG Xiang-ling, MA Guo-jie
“Change blindness” is a phenomenon that people fail to detect large changes of objects in visual scenes. The current study overviewed the phenomenon of change blindness in traffic scenes. We firstly reviewed specific factors in both scene change and driver characteristics that affected change blindness. Second, we proposed a conceptual model on the cognitive processes (attention, memory, comparison) underlying change blindness based on findings from cognitive psychology. Following the model, we discussed the practical implications to improve drivers' ability to detect changes and insights on future studies regarding change blindness in traffic safety.

LI Wan-yue; TAN Qun; LIU Shen; HAN Shang-feng; ZHANG Lin; XU Qiang
In order to explore the role of language context information in facial expression processing and recognition, the first experiment of this study investigated the effect of emotionality and self-relevance of language context on the processing of neutral emotional faces, and the second experiment investigated the effect on the processing of fear faces with different intensities. It was found that: The valence of neutral face was affected by the emotional type of language context information, and the valence of neutral faces in the positive contexts were significant higher than that in negative contexts. The arousal of neutral faces was affected by the self-relevance of language contextual information, and the arousal of neutral faces in the self-related context were significantly higher than that in other-related contexts. The emotional type of language contextual information also affect the judgment of facial expressions of different emotional intensity. Specifically, regardless of the intensity of emotion, the fearful faces in the negative language contexts were easier to be identified. Therefore, these findings suggest that the processing of facial expression was affected by the emotional and self-relevance of language contextual information. The effect of language context on the emotion inducing and enhancement of neutral faces, and the promoting effect of the faces to different emotional intensity when the emotional type of the language context and the face were consistent.

150 Evaluation bias of self-voice attractiveness and the role of depression
PENG Zhi-kang, WANG Xin-yu, LIU Hong-yan
To explore the differences of self-evaluation of voice attractiveness under different conditions and the role of depression in college students. Totally 66 students (34 females) were selected to complete the rating task with the subjective rating method which asked the participants to rate the attractiveness of self-voice, familiar-voice and strangers' voice. The differences of self-voice attractiveness evaluation under different conditions were compared, and the depression scale (Beck) was used to measure the depression level. The result shown both male and female participants had higher self-voice ratings. Depression level in women negatively predicted the evaluation bias of self-voice, i.e., as depression score raised, female's evaluation of self-voice attractiveness decreased. Ourfindingssuggested self-positive bias in voice attractiveness evaluation is a stable existence and is closely related to depression,the higher the degree of female depression is, the lower the evaluation of self-voice attractiveness is.

158 The influence of mindfulness on eating behavior and its functional mechanism
GONG Yan-ping,TAN Yu-xuan, XIE Ju-lan, LI Jian, CHEN Zhuo
Mindfulness, as the awareness that emerges through purposely and non-judgmentally paying attention to the present moment, has attracted increasing attention from researchers on eating behavior. After reviewing and summarizing relative existing studies, this paper finds that mindfulness plays an important role in correcting unhealthy eating behaviors，and awareness, acceptance and disidentification are its functional mechanisms. Besides, existing mindfulness-based methods for correcting unhealthy eating behaviors can be divided into two major categories of mindfulness state intervention and mindfulness-based clinical therapy. On this basis, this paper provides ideas that future research needs to further explore the role of mindfulness in healthy eating behavior, investigate the influence of mindfulness on eating behaviors from the perspective of life cycle, explore the functional mechanisms of mindfulness based on thought suppression, and test the boundary of correcting effects of mindfulness on unhealthy eating behaviors.

(2) Intrinsic motivation partially mediated the relationship between democratic governance of employment relations and employee creativity. (3) Organizational knowledge intensity moderated the relationship between democratic governance of employment relations and intrinsic motivation. (4) The interaction between democratic governance of employment relations and organizational knowledge intensity influenced employee creativity through intrinsic motivation.

CHEN Bi-zhong, ZHANG Qi-lin, ZHANG Rui-min, ZHENG Xue
Online social anxiety refers to the negative interpersonal experience such as tension and fear that people perceive in social media platforms, Online social anxiety includes three dimensions: privacy concern, interaction anxiety and fear of negative evaluation. Online social anxiety can be studied by qualitative analysis, experimental induction and scales. Online social anxiety is determined by the characteristics of social media itself, individual characteristic factors, cyberbullying as well as culture. Meanwhile, online social anxiety would also lead to social media burnout, affect the frequency, direction and way of users’ self-disclosure online, and make those commit to online safety behaviors. Future researches of online social anxiety should develop or revise effective localized scales, explore its psychological mechanisms, pay attention to the possible causes of online social anxiety paradox, and promote the intervention of online social anxiety.
