Dr Rick Hanson

American neuropsychologist and author whose Hardwiring Happiness presents the practice of taking in the good — deliberately dwelling on positive experiences to shift the brain's negativity bias through neuroplasticity.

Developed the most accessible and neuroscientifically grounded practice for counteracting the brain's negativity bias — the instruction to consciously dwell on positive experiences for 20-30 seconds to allow them to consolidate into lasting neural structure — making positive neuroplasticity practical.
