Personal Zen uses a neuroscience based technique called Attention Bias Modification (ABM) to re-train emotional and attentional patterns that can drive persistent feelings of anxiety and distress. ABM is a family of evidence-based cognitive training interventions that involve screen-based interactions with facial stimuli. Personal Zen is the first clinically validated ABM technique in the form of a mobile game.
Why Faces?
Even before babies can crawl, they can recognize the difference between a smiling face and an angry one. Facial expressions are unique in their ability to capture our attention and drive an emotional response. Through the repetition of interactions that focus attention on a pleasant face, ABM re-trains the associated neural pathways to produce positive mental health outcomes.
Through a decade of placebo-controlled, NIH-funded research and development, Personal Zen is the first and only clinically validated intervention to combine ABM with an engaging mobile game format.
Personal Zen’s proprietary game mechanics have been designed and optimized through a decade of neurocognitive research using:
Personal Zen’s game-based approach to the neurocognitive training technique attention bias modification (ABM) has been widely published in leading peer-reviewed research journals.
