Abstract
Competition is one of the basic social cognition modes during some social interaction activities. The brain activation of competition social cognition is not revealed yet. In this study we use Tetris as a media to create a competitive environment to obtain volunteers’ brain image through functional magnetic resonance imaging (fMRI). A specific experimental design, event-related design, was used in this study. Overall, we preliminary set up a experimental model using event-related fMRI design for the social cognition study by means of Tetris video game.
In the behavioral analysis, we found that there is no significant difference of mean score between playing with human or with the computer in the noncompetitive conditions, but with significant difference in competitive conditions. In the fMRI data analysis, the comparison of non-social related actions, translocating Tetris blocks versus rotating Tetris blocks, there is more obvious brain activation in fusiform gyrus no matter in competitive or non-competitive trial. And the comparison of social related actions, scoring /punished lines versus scoring 1 line, we found some regions such as right inferior parietal lobe and superior temporal gyrus more obvious in the interaction condition as the previous paper which might be related to competition. There is significant difference of brain activation areas between competitive and non-competitive conditions in the social related actions; take score lines event for example that there are more obvious brain activation areas in right caudate and left medial frontal gyrus in the competitive conditions. Furthermore, in the score lines event, there are more obvious brain activation areas such as left parietal lobe when competing with human and such as right hippocampus, left caudate, right superior frontal gyrus and left medial frontal gyrus when competing with the computer. We also find out there is significant influence of personality on the brain activation while playing Tetris.
In the future, it would be interesting to investigate more social cognition issue, such as cooperation. A cooperation mode of Tetris can be developed. We can also find out influence of different position while playing computer games with other equipments such as electroencephalography (EEG) or magnetoencephalography (MEG) involved. Moreover, we can set up a two MRI scanners connecting experimental environment. This allows for performance of human behavioral experiments in which participants can interact with each other while fMRI is acquired in synchrony with the behavioral interactions.
