Method for enhancing memory and cognition in aging adults
InactiveUS20050175972A1Improve “ noisy ” sensory representationShorten time constantMental therapiesElectrical appliancesRandom orderFormant
A method on a computing device is provided for enhancing the memory and cognitive ability of an older adult by requiring the adult to differentiate between rapidly presented stimuli. The method trains the time order judgment of the adult by presenting upward and downward frequency sweeps, in random order, separated by an inter-stimulus interval. The upward and downward frequency sweeps are at frequencies common in formants which form the frequency components common in speech. Icons are associated with the upward and downward frequency sweeps to allow the adult to indicate an order in which the frequency sweeps are presented (i.e., UP-UP, UP-DOWN, DOWN-UP, and DOWN-DOWN). Correct selection of an order causes the inter-stimulus interval to be reduced, and / or the duration of the frequency sweeps to be adaptively shortened.

A method on a computing device is provided for enhancing the memory and cognitive ability of an older adult by requiring the adult to differentiate between rapidly presented stimuli. The method utilizes a sequence of phonemes from a confusable pair which are systematically manipulated to make discrimination between the phonemes less difficult or more difficult based on the success of the adult. The manipulation includes processing of the consonant and vowel portions of the phonemes by emphasizing the portions, and / or by stretching the portions. Further processing includes separating the consonant and vowel portions by time intervals. As the adult improves in their auditory processing, the discriminations are made progressively more difficult by reducing the amount of processing to that of normal speech.

A method on a computing device is provided for enhancing the memory and cognitive ability of an older adult by requiring the adult to spatially match pairs of graphically presented response buttons that are associated with aurally presented stimuli which is processed by the computing device. An adult is presented with a grid of response buttons that have been paired with aural stimuli. As the adult selects a response button, its processed aural stimuli is presented. The adult is required to remember which response button is associated with which aural stimuli, and sequentially select response buttons having the same aural stimuli. As the adult sequentially selects response buttons having the same aural stimuli, the response button pair is removed. The number of response buttons presented in a trial, and the amount of processing applied to the stimuli adapts to the adults success or failure in completing trials. A method is provided for preventing chance sequential selection of response buttons having the same aural stimuli.
