Objective The study aimed to enhance transparency in autonomous systems by automatically generating and visualizing confidence and explanations and assessing their impacts on performance, trust, preference, and eye-tracking behaviors in human–automation interaction. Background System transparency is vital to maintaining appropriate levels of trust and mission success. Previous studies presented mixed results regarding the impact of displaying likelihood information and explanations, and often relied on hand-created information, limiting scalability and failing to address real-world dynamics. Method We conducted a dual-task experiment involving 42 university students who operated a simulated surveillance testbed with assistance from intelligent detectors. The study used a 2 (confidence visualization: yes vs. no) × 3 (visual explanations: none, bounding boxes, bounding boxes and keypoints) mixed design. Task performance, human trust, preference for intelligent detectors, and eye-tracking behaviors were evaluated. Results Visual explanations using bounding boxes and keypoints improved detection task performance when confidence was not displayed. Meanwhile, visual explanations enhanced trust and preference for the intelligent detector, regardless of the explanation type. Confidence visualization did not influence human trust in and preference for the intelligent detector. Moreover, both visual information slowed saccade velocities. Conclusion The study demonstrated that visual explanations could improve performance, trust, and preference in human–automation interaction without confidence visualization partially by changing the search strategies. However, excessive information might cause adverse effects. Application These findings provide guidance for the design of transparent automation, emphasizing the importance of context-appropriate and user-centered explanations to foster effective human–machine collaboration.

Objectives: Our study aimed to determine the impact of the COVID-19 pandemic on psychological responses and lifestyle changes among the general population in mainland China following the re-opening of the Wuhan city. Methods: A cross-sectional survey was conducted in April 2020. Participants of Chinese nationality aged ⩾ 18 years were asked to complete a modified validated Chinese version of a questionnaire regarding the impact of event scale (IES), family and social support, mental health–related lifestyle changes, and indicators of negative mental health impacts. Results: A total of 728 participants (i.e., 217 males and 511 females) completed the questionnaire. The mean age of the participants was 32.9 ± 10.4 years, with a majority of them (92.2%) having a higher educational qualification level. The overall mean IES in participants was 21.5 ± 7.0, reflecting mild stressful impact (i.e., following the re-opening of the Wuhan city); 25.5% of the participants had an IES score ⩾ 26. Being females and married were significantly associated with a higher mean IES score. The overall mean scores for intrusion and avoidance score scales in participants were 9.4 ± 3.7 and 12.1 ± 4.2, respectively. Conclusions: The COVID-19 pandemic was associated with increased stressful impact in our participants following the re-opening of the Wuhan city when compared with our previous study, which should not be taken lightly.

AbstractConflict in peer and family relationships becomes more common in the adolescent period when compared to previous developmental periods. These typical developmental challenges can be exacerbated in the context of poor emotion regulation skills. Using daily diary data, the current study examined the stress spillover effects of peer and family stress on one another, as well as the moderating role of emotion regulation challenges (i.e., emotional inhibition, dysregulation). A sample of 310 Chinese adolescents (Mage = 13.02 years, SD = 0.76 years, 50.7% boys) completed an initial measure of emotion regulation difficulties, then reported on peer and family stress for 10 consecutive weekdays. Results indicated that there was an overall same-day peer stress spillover effect in which adolescents' peer stress on a given day was negatively associated with later conflictual interactions with their parents. Further, the relation between peer stress and same- and next-day family stress was exacerbated in the context of high levels of emotional inhibition. Family stress did not significantly relate to next-day peer stress, nor was this association moderated by difficulties with emotion regulation. These results highlight the temporal sequence of daily peer-to-family stress spillover. Though emotional inhibition may be culturally adaptive for maintaining interpersonal harmony, it can be maladaptive in managing stress for Chinese adolescents.

AbstractPhysiological synchrony is an important biological process during which parent–child interaction plays a significant role in shaping child socioemotional adjustment. The present study held a context‐dependent perspective to examine the conditional association between parent–child physiological synchrony and child socioemotional adjustment (i.e., relationship quality with parents and child emotion regulation) under different (i.e., from highly unsupportive to highly supportive) emotional contexts. One hundred and fifty school‐age Chinese children (Mage = 8.64 years, 63 girls) and their primary caregivers participated in this study. After attaching electrocardiogram (ECG) electrodes, parent–child dyads were instructed to complete a 4‐minute conflict discussion task. Parent–child physiological synchrony was calculated based on the within‐dyad association between parents' and children's respiratory sinus arrhythmia (RSA) levels across eight 30‐second epochs. Parental emotional support, child relationship quality with parents, and child emotion regulation during the discussion task were coded by trained research assistants. Supporting our hypotheses, parental emotional support moderated the relations of parent–child RSA synchrony with both child relationship quality with parents and child emotion regulation. Furthermore, the Johnson‐Neyman technique of moderation indicated that the associations between parent and child RSA synchrony and child socioemotional adjustment indicators shifted from negative to positive as the parental emotional support became increasingly high. Our findings suggest that parent–child physiological synchrony may not be inherently adaptive or maladaptive, highlighting the importance of understanding the function of parent–child physiological synchrony under specific contexts.Research Highlights
Physiological synchrony may not be inherently adaptive or maladaptive, and the meanings of parent–child physiological synchrony might be contingent on contextual factors.
Parental emotional support moderated the relations between parent–child respiratory sinus arrhythmia (RSA) synchrony and child socioemotional adjustment indicators (i.e., child relationship quality with parents and child emotion regulation).
More positive/less negative parent–child RSA synchrony was associated with better child socioemotional adjustment under a supportive emotional context, whereas with poorer child socioemotional adjustment under an unsupportive emotional context.
These findings highlight the significance of considering the emotional context in physiological synchrony studies.
