How the Brain Translates Money into Force: A Neuroimaging Study of Subliminal
Motivation, Science
 









Excerpts: Unconscious motivation in humans is often inferred but rarely
demonstrated empirically. We imaged motivational processes, implemented in a
paradigm that varied the amount and reportability of monetary rewards for which
subjects exerted physical effort. We show that, even when subjects cannot report
how much money is at stake, they nevertheless deploy more force for higher
amounts. Such a motivational effect is underpinned by engagement of a specific
basal forebrain region. Our findings thus reveal this region as a key node in
brain circuitry that enables expected rewards to energize behavior, without the
need for the subjects`awareness.
