This technology relates to a closed-loop controller that is being developed as a phone app for emotional self-regulation in real-time. There is a significant association between emotion dysregulation and symptoms of depression, anxiety, eating pathology, and substance abuse, affecting millions worldwide. Consisting of a closed-loop controller that adjusts reward values in real-time according to individual mood response, the Mood Machine Interface technology compensates for adaptation to stimuli over time allowing it to generate substantial mood changes in the user. This provides a quantitative assessment of mood that is independent of the user being aware of the experimental goal.
This technology provides a superior alternative to current technologies, which are qualitative, and where participants are aware of the experimental goal.
