abstract = {This study aimed to compare a neuropsychological test tapping into executive control function, the Wisconsin Card Sorting Test (WCST), performed in either traditional paper-and-pencil (PP) or virtual reality (VR) modality, and to determine the role of human factors (i.e., sense of presence, cybersickness, field (in)dependence and video game experience) as contributors to performance and perceived mental effort. Indeed, if virtual assessment might bring the ecological dimension to controlled laboratory research, it is often suggested that human factors might bias performance. WCST performance and its associated perceived mental effort were compared between the two modalities (N = 107). In the VR modality (N = 52), a correlation matrix was conducted as well as a cluster analysis in order to build two experimental groups, or profiles, based on their subjective experience of VR. WCST performance and perceived mental effort were then compared between these two groups while controlling for age and education. Results outlined a similar WCST performance and perceived mental effort between the PP and VR modalities. However, when comparing the two VR groups, results suggest that an unfavorable profile for VR, i.e., less sense of presence, more cybersickness, more visual field dependence and less video game experience, is associated with greater perceived mental effort. These experimental findings enable outlining a new conceptual and methodological framework for the assessment of executive control task performance in VR. Results could help users to take human factors into consideration in order to fully exploit or predict the benefits of this tool. © 2022, The Author(s), under exclusive licence to Springer-Verlag London Ltd., part of Springer Nature.},

abstract = {The aim of this research is to study the impact of coopetition on the market performance of product innovation. Previous research suggests, on the one hand, that coopetition is a powerful strategy for innovation but, on the other hand, that coopetition creates opportunism risk. Therefore, the impact of coopetition on innovation depends on external and internal conditions. This impact also differs according to the radicalness of the focal innovation. Past studies have identified many different factors that influence the impact of coopetition on innovation. However, they have not taken into account the different types of coopetition. To fill this gap, here, 1) we introduce a key distinction between the two main types of coopetition, i.e., vertical vs horizontal coopetition and 2) we distinguish between the impacts of these two types of coopetition on the market performance of two types of innovation, i.e., incremental vs radical innovation. We build a set of four hypotheses and test them on a sample of 763 new products in the video game industry. The results show that 1) horizontal coopetition has a positive impact on the market performance of radical and incremental innovation, 2) horizontal coopetition has a greater impact on the market performance of radical innovation 3) vertical coopetition has no impact on the market performance of innovation, and 4) the null impact of vertical coopetition is true for both radical and incremental innovation. © 2021},
