However, few studies have utilized VR technology to examine variables that would otherwise be difficult to manipulate in the lab. This study examined the impact of a large VR audience (i.e., 200 members) on the physiological (i.e., cortisol) and psychological responses of 140 individuals. Participants were randomly assigned to one of three conditions: an in-person (2-person) audience, VR 2-person audience, or a VR 200-person audience condition. Salivary cortisol was collected to assess physiological reactivity and recovery. Participants self-reported psychological responses to the TSST including stress, arousal, emotions, and perceptions of the audience. Results revealed that all conditions elicited stress reactivity. The VR 200-person condition resulted in greater cortisol concentrations and more negative affect than the small VR 2-person audience. Thus the effectiveness of a VR-TSST may be enhanced by the use of a larger virtual audience stimulus.","PeriodicalId":33466,"journal":{"name":"International Journal of Virtual Reality","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-04-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"41766853","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Examples of such tools applied in the manufacturing education are: different types of Petri Nets (including coloured Petri Nets), different toolboxes from Matlab, AnyLogic and FlexSim. Moreover, artificial intelligence provides methods and techniques that can significantly improve the performance of developed simulations. The paper presents a simulator developed using Petri NET toolbox in scope of representing the process of a manufacturing line for better understanding of the correlation between the theoretical control and the behaviour of the system. It tackles in a different way the learning process addressed to students to a more practical view of the control algorithm.","PeriodicalId":33466,"journal":{"name":"International Journal of Virtual Reality","volume":"32 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-12-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"78851225","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
