Sensors may electronically activate the automatic scent diffusion device during particular moments to reinforce behaviors that support satiation and/or rebuff behaviors that contribute to weight gain.
  • Aroma diffusion may be performed by manual release using a manually actuated control device connected to the scent diffuser. Users may expect that experiencing the stimulus in the form of an aroma will be accompanied with a conditioned response that supports satiation strategies.
