A computer-implemented method is described for assessing an aging adult's ability to integrate visual-spatial and auditory memory by requiring the adult to spatially match pairs of graphically presented response buttons that are associated with aurally presented stimuli which is processed by a computing device. The adult is presented with a grid of response buttons, each associated with an aural stimulus. When the adult selects a response button, its aural stimulus is presented. The adult is required to consecutively select a response button having the same aural stimulus. As the adult sequentially selects response buttons having the same aural stimuli, the button pair is removed. First assessment trials are performed for a first plurality of grids, training trials are performed for a second plurality of grids, then second assessment trials performed for the first plurality of grids. The adult's performances in the two assessments are compared to determine the adult's improvement.
