Using experimental methods, we find that limiting user participation, particularly in providing negative feedback, significantly reduces perceptions of procedural and overall fairness. Notably, users who highly value self-expression are especially sensitive to these restrictions, showing heightened concern when their ability to contribute is curtailed. Our research establishes a direct link between changes in engagement policies and user perceptions of fairness and trust, suggesting that prioritizing content creators over users may undermine trust and future usage intentions. Furthermore, procedural fairness is affected by the opportunity to provide feedback, irrespective of its influence on outcomes. These insights underscore the importance of tailoring engagement policies to the platform's primary function, whether for socializing, entertainment, or information sharing.</div></div>","PeriodicalId":48471,"journal":{"name":"Computers in Human Behavior","volume":"167 ","pages":"Article 108609"},"PeriodicalIF":9.0,"publicationDate":"2025-02-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143464077","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"心理学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Understanding how different aspects of avatar behaviours influence various types of social interactions is crucial for improving the design of CVEs. Grounded in a theoretical framework based on avatar anthropomorphic realism, nonverbal social cues, eye-mind hypothesis, and interaction process analysis, this study investigates the impact of avatars’ gaze behaviours on users’ attention allocation and perceptions during AMC in CVEs. A two-arm randomised controlled trial (RCT) with 60 participants (29 males and 31 females) compared static gaze and natural gaze avatars during socio-emotional and task interactions. Three-dimensional eye-tracking data revealed distinct attention patterns across three primary nonverbal social cues: eye gaze, head orientation, and pointing gesture. Furthermore, avatars’ gaze type and interaction type were both found to significantly affect participants’ attention allocation; natural gaze behaviour and task interactions mitigated the general gaze-avoidance pattern observed in previous studies. However, avatars’ gaze type did not impact participants’ perceptions of social presence and anxiety. This research provides a nuanced understanding of attention allocation across nonverbal social cues during AMC and underscores the importance of avatars’ gaze and interaction types, highlighting important implications for the future design of CVE to enhance attention coordination and communication. Additionally, it calls for more comprehensive studies to explore avatars’ anthropomorphic realism and its effects on user perceptions and overall experience during AMC.</div></div>","PeriodicalId":48471,"journal":{"name":"Computers in Human Behavior","volume":"167 ","pages":"Article 108598"},"PeriodicalIF":9.0,"publicationDate":"2025-02-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143445779","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"心理学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This paper presents adaptive transaction management protocols for edge-cloud systems. We propose EC-Lock which transitions between non-blocking and blocking phases, and EC-OCC which distinguishes edge and cloud transactions during timestamp validation. These hybrid techniques reduce unnecessary blocking and restarts. Simulation studies demonstrate that EC-Lock and EC-OCC provide substantial performance gains over traditional protocols under diverse workloads. By balancing consistency and efficiency, the proposed protocols enable scalable edge-cloud transaction processing.

However, service failures with AI engagement are inevitable. How to provide service recovery for AI service failures to increase consumer reuse intention is an important issue. The current study investigated AI service recovery, examining the remediation effect of AI warm response on service failure. Through four experiments, the results suggested that AI high warm response increased consumer reuse intention in service recovery, and social presence mediated this relationship between AI warm response and consumer reuse intention. Moreover, the positive recovery effect of AI warm response was significant only under conditions of low service failure severity. Additionally, the compensatory effect of human intervention in service recovery was significant exclusively when following an AI low warm response, rather than a high warm response. The findings not only extend the knowledge regarding the reuse of AI agents after service failure but also reveal the potential of AI warm response in service recovery strategies. Furthermore, they also encourage AI service providers to elevate the warmth level of AI agents’ response to recover general service failure and minimize the reliance on human intervention.</div></div>","PeriodicalId":48471,"journal":{"name":"Computers in Human Behavior","volume":"166 ","pages":"Article 108606"},"PeriodicalIF":9.0,"publicationDate":"2025-02-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143428030","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"心理学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
