Primary |
General intellectual functioning, including visual-spatial reasoning |
The Perceptual Reasoning Index (PRI) of the revision of the Wechsler Abbreviated Scale of Intelligence (WASI-II). PRI includes the subtests Block Design and Matrix Reasoning. The Raw scores of the subtests are converted to T-scores, which are summed for a Sum of T-scores for Perceptual Reasoning. The Sum of T-scores for Perceptual Reasoning is converted to a Composite Score of the PRI, which can be used to find the Percentile Rank. The Block Design raw scores range from 0-51 and the Matrix Reasoning raw scores range from 0-23. The T-score ranges are from 20-54. The Composite Scores range from 40-160.The higher the scores of the subtests, the higher the score on the PRI, the greater the subject's ability to analyze and synthesize abstract visual stimuli and the subject's fluid intelligence, broad visual intelligence, classification and spatial ability, knowledge of part-whole relationships, simultaneous processing, and perceptual organization. |
Initial assessment and Follow-up assessment (6-8 weeks after Initial assessment) |

Primary |
Basic visual perception, visual-motor integration, and graphomotor skills |
The Beery-Buktenica Developmental Test of Visual Motor Integration 6th Edition (Beery VMI). The composite score is the sum of the scores of three subtests: Visual-Motor Integration, Visual Perception, and Motor Coordination. The scores for the subtests are calculated using pre-formatted tables to determine the standard score, scaled score, and percentile based off of the raw score. The composite score has a mean of 100 and a standard deviation of 15 for all ages groups, and are based on the means of raw score distribution. The higher the score, the higher the percentile, the greater the subject's ability for visual perception, visual motor-integration, and graphomotor skills. |
Initial assessment and Follow-up assessment (6-8 weeks after Initial assessment) |
|
Primary |
Visual-spatial processing |
The Arrows subtest of the revision of A Developmental Neuropsychological Assessment (NEPSY-II), designed to assess the ability to judge line orientation. The Arrows subtest-level scores range from 1-19, with a low score indicating poor visuospatial skills, while a high score indicates excellent visuospatial skills. |
Initial assessment and Follow-up assessment (6-8 weeks after Initial assessment) |
|
Primary |
Visual-spatial processing and mental rotation |
The Geometric Figures subtest of the revision of A Developmental Neuropsychological Assessment (NEPSY-II), designed to assess mental rotation, visuospatial analysis, and attention to detail. The Geometric Figures subtest-level scores range from 1-19, with a low score indicating difficulty with visuospatial perception, including mental rotation and with a high score indicating excellent visuospatial perception. |
Initial assessment and Follow-up assessment (6-8 weeks after Initial assessment) |
|
Primary |
Selective visual attention |
The Cancellation subtest of the revision of the Wechsler Intelligence Scale for Children (WISC-IV), designed to measure processing speed. The Raw Score is converted to a Scaled Score (1-19), which is converted to a Percentile Rank. The higher the raw score, the higher the Scaled Score, and the Percentile Rank. The higher the score, the better the visual processing speed. |
Initial assessment and Follow-up assessment (6-8 weeks after Initial assessment) |
|
Primary |
Visual-spatial decision making and visual-motor speed |
Coding subtest of the revision of the Wechsler Intelligence Scale for Children (WISC-IV), designed to measure visual-motor speed and complexity and motor coordination. The Raw Score is converted to a Scaled Score (1-19), which is converted to a Percentile Rank. The higher the raw score, the higher the Scaled Score, and the Percentile Rank. The higher the score, the better the visual-spatial and visual-motor skills. |
Initial assessment and Follow-up assessment (6-8 weeks after Initial assessment) |
|
Primary |
Fine motor dexterity |
The Purdue Pegboard test, designed to measure manual dexterity and bimanual coordination.The test is comprised of 5 scores, each of the subtests are timed. Scores are continuous, the higher the score the greater the subjet's manual dexterity and bimanual coordination. |
Initial assessment and Follow-up assessment (6-8 weeks after Initial assessment) |
|
Primary |
Visual-motor control |
The Visuomotor Precision subtest of the revision of A Developmental Neuropsychological Assessment (NEPSY-II), designed to assess graphomotor speed and accuracy. The Visuomotor Precision subtest-level scores range from 1-19, with a low score indicating difficulty with visuomotor control and with a high score indicating excellent visuomotor skills. |
Initial assessment and Follow-up assessment (6-8 weeks after Initial assessment) |
|
Primary |
Neuroanatomical alterations in brain tissue structure |
Diffusion Tensor Imaging (DTI) scan: a spin-echo EPI DTI sequence (FOV = 240 x 240 mm, matrix = 96 x 96, in-plane resolution = 2.5 x 2.5 mm, slice thickness = 2.5 mm, number of slices =76, TR/TE = 9400/93.2 msec; sense factor = 2; NEX = 2). DTI measures anisotropic diffusion properties via diffusion indices. |
Baseline MRI and Follow-up MRI (6-8 weeks after Baseline MRI) |
|
Secondary |
Adherence to the training plan |
Adherence to the training plan will be evaluated using performance data collected by the apps. If performance data is not available from the apps, the participants will be given an activity log to record their usage time, games played, and scores obtained. Eighty-percent completion of the recommended time (24 hrs = 6 wks x 4 days/wk x 1 hr/day) is the goal of the study. |
