20100041001 | VISUAL DIVIDED ATTENTION TRAINING - 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. | 02-18-2010 |
20090130640 | N-BACK EXERCISE FOR TRAINING COGNITION - Computer-implemented method for improving cognition. Multiple first and second stimulus elements are provided, where some of the second elements correspond to the first elements. A sequence of first stimulus elements is presented, each element presented for a duration separated by an interval. After a specified delay period, equal to the duration plus the interval, times a non-integer factor N, a sequence of groups of second elements is presented concurrently with the sequence of first elements, where each group includes a matching second element that matches a corresponding first element presented earlier by the specified delay period, i.e., presented N first elements back. For each presented group, the participant indicates the matching second element, or a second element in the group that doesn't match. The delay period is modified based on whether the participant responded correctly. The presenting, presenting, requiring, determining, and modifying are repeated in an iterative manner. | 05-21-2009 |
20090051877 | COGNITIVE TRAINING USING GUIDED EYE MOVEMENTS - 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. | 02-26-2009 |
