If you believe some other barrier or principle should be included in the mosaic, please describe it and how it would affect the positioning of your initiative in the mosaic:
From a scientific point of view, barriers to the use of computer games to enhance neurocognitive health include insufficiently precise knowledge about how much of what kind of cognitive stimulation, starting at what age, is necessary to maintain cognitive acuity or to forestall neurocognitive decline with age. More studies will address the specific populations that might derive optimal benefit from these activities. Those with mild cognitive impairment and those with early signs of dementia.
Another question involves whether exercising a single, specific cognitive function is better than training multiple functions simultaneously.
Further, motivational factors may also constitute another barrier: Neurocognitive stimulation that is not inherently fun and rewarding may not be compelling enough to maintain consumers' interest and engagement.
