Data from 210 undergraduate students across diverse university professional programs were analyzed using a structural equation model. As higher education institutions strive to enhance their curricula by incorporating gamification technologies, it is crucial to understand both the potential benefits and risks. Misapplication these technologies can negatively affect learning outcomes, emphasizing the need for informed implementation of pedagogical strategies. This study demonstrates that characteristics associated with the virtual environment, such as interaction and immersion, significantly enhance students' creativity and comprehension. Ensuring robust interaction and immersion within virtual learning environments correlates with heightened performance expectancy, fostering a more effective and engaging educational experience.

Over the past few decades, extensive research has been conducted on immersion. However, there remains a lack of consistency in how the term is defined and applied in the literature. Additionally, there is no clear and consistent conceptual hierarchy of related terms across different measurement models. To address these issues, this paper explores the multidimensionality of immersion, as well as associated concepts such as presence and involvement. From this, a unified conceptual model of immersive experience is proposed for future studies in XR. The model defines physical presence, social presence, self presence and involvement as the core dimensions of an immersive experience, which arise from sensorimotor, task/motor and narrative engagement. Plausibility, interactivity, and interestingness are identified as key properties of immersive systems and content that fascilitate engagement, each of which is influenced by subjective factors: internal reference, skills/knowledge and personal preference, respectively. This model provides a comprensive framework for researchers to measure immersive experiences more consistently and build a coherent body of research in XR.</div></div>","PeriodicalId":72681,"journal":{"name":"Computers in human behavior reports","volume":"18 ","pages":"Article 100663"},"PeriodicalIF":4.9,"publicationDate":"2025-03-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143791481","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Utilizing a quantitative research design with 310 participants, this study employs partial least squares structural equation modeling (PLS-SEM) to analyze the effects of anthropomorphic factors, such as animacy, humanlike fit, and perceived sociability, on the likeability of AI-generated singing. The findings indicate that animacy and humanlike fit significantly enhance likeability, which, in turn, influences the intention to use AI-generated singing. Curiosity and word of mouth (WoM) emerged as key drivers of acceptance. This study builds on the traditional technology acceptance models (TAM, UTAUT2) by proposing a framework that integrates human-related factors, thereby demonstrating the necessity of adapting existing models to better evaluate AI systems in creative domains.

Multilevel modeling results revealed several cross-level interactions: For people with lower thought control ability, deleting files resulted in higher mental effort and lower task performance. Sorting files led to higher task focus and work performance, but only for people with higher thought control ability. Overall, sorting and deleting seem to be beneficial when people are also able to successfully control thoughts.
