Abstract Computer gaming is one of the most common activities that individuals are indulged in their usual activities concerning interactive system-based entertainment. Visuospatial processing is an essential aspect of mental rotation (MR) in playing computer-games. Previous studies have explored how objects’ features affect the MR process; however, non-isomorphic 2D and 3D objects lack a fair comparison. In addition, the effects of these features on brain activation during the MR in computer-games have been less investigated. This study investigates how dimensionality and angular disparity affect brain activation during MR in computer-games. EEG (electroencephalogram) data were recorded from… More >

Abstract In performing a gaming task, mental rotation (MR) is one of the important aspects of visuospatial processing. MR involves dorsal-ventral pathways of the brain. Visual objects/models used in computer-games play a crucial role in gaming experience of the users. The visuospatial characteristics of the objects used in the computer-game influence the engagement of dorsal-ventral visual pathways. The current study investigates how the objects’ visuospatial characteristics (i.e., angular disparity and dimensionality) in an MR-based computer-game influence the cortical activities in dorsal-ventral visual pathways. Both the factors have two levels, angular disparity: convex angle (CA) vs. reflex angle… More >

Abstract Mental rotation (MR) is an important aspect of cognitive processing in gaming since transformation and manipulation of visuospatial information are necessary in order to execute a gaming task. This study provides insights on saccadic characteristics in gaming task performance that involves 2D and 3D isomorphic objects with varying angular disparity. Healthy participants (N = 60) performed MR gaming task. Each participant was tested individually in an acoustic treated lab environment. Gaze behavior data of all participants were recorded during task execution and analyzed to find the changes in spatiotemporal characteristics of saccades associated with the variation in angular… More >
