I’m really disappointed in this article. It’s pretty weak science; self-report checklists about thinking about an action while at the same time as performing the action.
Mindfulness, in the way it is described here does not ring true to me.
Thinking about consciousness while one is engaged in an action is a double act of attention that detracts from our engagement in the activity, whether it is exercise or washing dishes. It also is a poor substitute for putting in a daily hour of an actual meditation technique.
[Disclaimer: I didn’t come up with this critique. I heard Maharishi MaheshYogi talk about this way back in 1974.]
