A computer-implemented method for enhancing cognitive ability of an older participant by requiring the participant to differentiate between rapidly presented visual stimuli. First and second visual sweeps are provided for visual presentation to the participant, e. g. , spatial frequency or orientation sweeps. At least two visual sweeps are visually presented to the participant utilizing the first visual sweep, the second visual sweep, or a combination. The participant is required to indicate an order in which the at least two visual sweeps were presented. A determination is made regarding whether the participant indicated the order of the visual sweeps correctly. The visually presenting, requiring, and determining are repeated one or more times in an iterative manner to improve the participant's cognition. The duration of the sweeps may be adjusted based on the correctness/incorrectness of the participant's response according to a maximum likelihood procedure. Assessments may be made during the exercise.

A computer-implemented method for enhancing cognition, e.g., for improving cognitive ability of a participant using visual stimuli. A set (or sets) of visual stimuli is provided for visual presentation to the participant. A visual stimulus from the set is visually presented to the participant. The participant is required to respond to the visual stimulus. A determination is made regarding whether the participant responded correctly. The stimulus intensity of the visual stimuli presented may be adjusted based on the correctness/incorrectness of the participant's response according to a single-stair maximum likelihood (e.g., ZEST) or N-up/M-down procedure. The visually presenting, requiring, and determining are repeated one or more times in an iterative manner to improve the participant's cognition, e.g., ability to process visual information, memory, etc. Assessments may be performed during the repeating according to a dual-stair maximum likelihood (e.g., ZEST) or N-up/M-down procedure. The repeating may include performing multiple exercises using visual stimuli.

Computer-implemented method for enhancing cognitive ability of a participant using guided eye movements. Multiple graphical elements are provided for visual presentation to the participant, each having a value. A temporal sequence of at least two of the graphical elements are visually presented at a specified stimulus intensity, e.g., duration or presentation time, including displaying the value of each graphical element at a respective position in a visual field for a specified duration, then ceasing to display the value. The participant is required to respond to the displayed values. A determination is made as to whether the participant responded correctly, and the stimulus intensity modified in response, e.g., using a maximum likelihood procedure. The visually presenting, requiring, determining, and modifying are repeated in an iterative manner to improve the participant's cognitive skills. Periodically, assessments of the participant's progress are performed, e.g., using the maximum likelihood procedure.

Computer-implemented method for enhancing a participant's cognition, including, e.g., visual memory, utilizing a computing device to present visual stimuli for training, and to record responses from the participant. Multiple graphical elements are provided for visual presentation to the participant. A temporal sequence of a plurality of the graphical elements is visually presented, including displaying each graphical element in the sequence at a respective location in a visual field for a specified duration, then ceasing to display the graphical element. The presented graphical elements include at least two matching graphical elements. The participant is required to respond to the presented sequence, including indicating locations of matching graphical elements. A determination is made as to whether the participant responded correctly, and the duration modified based on the determining. The visually presenting, requiring, determining, and modifying are repeated one or more times in an iterative manner to improve the participant's cognition.
