The Goalkeeper Game is a computer game being developed by the NeuroMat team since June 2015, associated with the experimental protocol being developed with plasticity in brachial plexus avulsion. In this game, brain signatures are evaluated through the performance of the participant in guessing the next direction chosen by the penalty-taker. The system records the sequence of guesses of the player, who must identify the context tree model used by a virtual penalty-taker.
In this way, the game allows for cheap and large-scale reaction time and error rate data collection, offering an alternative and complementary means to infer about brain functioning. The game’s source code is open, and the latest version is freely available at game.numec.prp.usp.br.
