An Investigation of Computer-based Brain Training on the Cognitive and EEG Performance of Employees *

Neurocognitive skills (e.g., processing speed, attention and memory) were hypothesized to be critical for workplace performance and by extension for the work-life balance of employees. Twenty-one employee volunteers underwent a neurocognitive training program – which consisted of an initial pre-test assessment, a six week "boost" or intervention period, and then a re-assessment to track the progress of each participant. A median split of the group created two training groups: a long-training group that averaged 30 hours of total training during the boost period; and a short-training group that averaged 7 hours of training. On pre-training measures of neurocognitive performance, group differences in performance did not reach statistical significance. Following training participants experienced a positive impact from the program as measured in three ways: standardized higher behavioral metrics, improved cognitive state metrics using EEG and positive self-reported data. From a quantitative perspective, participants’ cognitive efficiency increased by 12% for the high-training group and 5% for the low-training group (cognitive efficiency refers to a behavioral measure which combines accuracy and speed). Qualitatively, study participants reported improvements in their productivity and mental performance post-study.
