Abstract: Computer-implemented method for enhancing cognitive ability of a participant using multiple object tracking. One or more images are provided and are available for visual presentation to the participant. A plurality of images based on the one or more images are visually presented, including multiple target images and multiple distracter images, where each of the target images is graphically indicated for a first time period, and then each of the images is moved for a second time period during which the graphically indicating is not performed. The participant is then required to select the target images from the plurality of images, and a determination is made regarding the selection's correctness/incorrectness. The visually presenting, requiring, and determining are repeated one or more times in an iterative manner to improve the participant's cognition. The stimulus intensity may be adjusted each iteration based on the participant's response. Assessments may be performed.

Abstract: 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.
