Computer-implemented method for enhancing cognition of a participant. A first target image of a set of target images is visually presented for a specified presentation time at a first location in a visual field that includes multiple peripheral locations, each at least a specified distance from the first location. Substantially simultaneously, a first peripheral location in the visual field is visually indicated for the presentation time, after which the visually presenting and indicating are ceased. Candidate target images with a specified discriminability are visually presented, including the first target image. The participant is required to select the target image from among the candidates. If the participant correctly selected the first target image, the participant is required to select the first peripheral location from the multiple peripheral locations. The presentation time is adaptively modified based on the correctness/incorrectness of the participant's selections. The process is repeated to improve the participant's cognition.

Visual divided attention training

A system for training the visual attention capabilities of a subject presents a series of sets of tests to the subject on a conventional touch screen monitor. Each test includes a central target, a peripheral target and distractor elements around the peripheral target. The display time for the displays and the eccentricity of the peripheral target are held constant within each set of tests. When the subject reaches a desired level of success in identifying the central target and in locating the peripheral target, eccentricity of the peripheral target is increased for the next set of tests. Once eccentricity reaches a maximum value, display time is decreased and eccentricity is decreased for the next set of tests.
