Listen is an auditory training game produced by the University of California Riverside (UCR) Brain Game Center for Mental Fitness and Well-being; A research unit focused on brain fitness methods and applications. Listen integrates principles of perceptual learning and auditory neuroscience in a reward-based game framework that reinforces program adherence and maintains training efficacy. In the game experience, players find themselves in control of a wisp that must navigate through perilous obstacles by responding appropriately to specific sound cues in order to absorb energy from objects in the environment. The sound cues are based upon language primitives and sound features that selectively drive neurons in the auditory cortex of the brain. While at first the sounds are easy to discriminate, the game’s adaptive algorithms measure each players’ ability to discern the sounds and trains players at their individual threshold of performance. Give it a listen and train your hearing.
