Short Biography

I am Kavous Salehzadeh Niksirat; a postdoctoral fellow (research scientist) at the University of Lausanne (UNIL), where I work on addressing online privacy violations committed by individuals, in the framework of the NudgeMPC SNSF project. Before joining UNIL, I was working as a postdoctoral fellow at the HCI Group, EPFL. Prior to that, I was a visiting researcher at the Center for Human-Engaged Computing, Japan, in 2018. I earned my Ph.D. degree in human-computer interaction (HCI) from Kochi University of Technology, Japan in 2018. I was working at the intersection of digital health interventions and well-being. My research aim was to investigate the principles underlying the design and development of interventions to improve mental and physical well-being.

This study demonstrates how playing a well-designed multitasking motion video game in a virtual reality (VR) environment can positively impact the cognitive and physical health of older players. We developed a video game that combines cognitive and physical training in a VR environment. The impact of playing the game was measured through a four-week longitudinal experiment. Twenty healthy older adults were randomly assigned to either an intervention group (i.e., game training) or a control group (i.e., no contact). Participants played three 45-min sessions per week completing cognitive tests for attention, working memory, reasoning and a test for physical balance before and after the intervention. Results showed that compared to the control group, the game group showed significant improvements in working memory and a potential for enhancing reasoning and balance ability. Furthermore, while the older adults enjoyed playing the video game, ability enhancements were associated with their intrinsic motivation to play. Overall, cognitive training with multitasking VR motion video games has positive impacts on the cognitive and physical health of older adults.

Flow Proneness - FP (i.e., dispositional tendency to experience flow) is subjectively different across individuals. An earlier study demonstrated that FP is correlated with the availability of dopamine receptors in the dorsal striatum including the caudate and the putamen. However, it remains unclear whether FP is associated with gray matter volume variations in the brain. The neuro-anatomical basis of FP has been investigated for the first time in the present study. We conducted a cross-sectional study with a high number of healthy employed Japanese adults (n = 680). We measured FP in different domains of everyday life (work, household maintenance, and leisure time) using a Japanese translation of a Swedish flow proneness questionnaire. We investigated gray matter volume using optimized voxel-based morphometry. As hypothesized, we found a significant region in the dorsal striatum. Our results indicate that an increase in gray matter volume in the right caudate is associated with an increase in overall FP in everyday life. However, the resulting correlation was relatively small (0.13). We discuss the potential reasons underlying these findings. Our findings might have further implications for flow research and well-being.
