Not the past, not what might happen in the future. Fuzzy, intuitive, today’s emotions. Nonlinear, visual, big picture. Attention flows toward good, bright, happy visualizations.
Opening your mind to nonlinear thinking may provide cognitive reserve that helps you as cognitive functions start to decline perhaps precipitously into dementia. Neuroplasticity is a mechanism that the brain will uses to reassign functional processing from one area to the brain as it is damaged by trauma or disease.
One very good way to encourage the development of cognitive reserve and neuroplasticity is to practice nonlinear thinking methods that can help promote mindful solutions. Should the brain become damaged, it may be able to use nonlinear, symbolic visual thinking to cope, at least for a while. And while you practice you may also experience strength in your resolve and understanding.
Do note that the above comments are speculative. There is NO formal research on mind mapping nor other comments about this in the literature (other than my own). Also this is based only on my own experience and generalizations from my earlier research on daydreaming and imagery. So do not go about thinking that this proven. Rather it is speculative.
While I theorize that mind mapping is related to mindfulness in SOME applications, even if it turns out that it is not — from the results of formal empirical studies — there are other demonstrated benefits from mind mapping, so the actual use of mind mapping should still be encouraged.
