Summaries of independently published NeuroTracker studies investigating assessment of human performance.
The aim of this study was to examine the effects of NeuroTracker training on standardised measures of attention, working memory, and visual information processing speed using standardized neuropsychological tests. Additionally functional brain imaging measures were used to investigate associated changes in brainwave activity.
20 university-aged students were recruited and divided into an active NeuroTracker training group (30 sessions of NeuroTracker) and a non-active control group. Cognitive functions were assessed pre- and post-training using standardized neuropsychological tests (IVA+Plus, WAIS-III, D-KEFS), along with correlates of brain functions via detail quantitative electroencephalography (qEEG) brain scans.
The trained group showed strong and consistent improvements in NeuroTracker speed thresholds throughout the training period. Post-training the NeuroTracker group demonstrated significantly higher scores on the IVA+Plus Auditory, WAIS Symbol Search, WAIS Code, WAIS Block Design, WAIS Letter-Number Sequence, d2 Test of Attention, and D-KEFS Color Naming, Inhibition and Inhibition/Switching subtests (P < .01).
For qEEG measures the NeuroTracker group demonstrated significant relative power increases in a range of frequencies within the beta bandwidth, with both eyes open and closed resting states. These changes were observed across frontal regions of the brain involved with executive functions, and represented increases in brain wave speed associated with widely heightened brain activity and signatures of enhanced neuroplasticity.
Overall results indicated that NeuroTracker training can enhance attention, information processing speed, and working memory, and also lead to sustained and positive changes in neuroelectric brain function.
