mHealth Behavior Study

Implicit approach bias is the behavioral action tendency to be faster to approach rather than avoid cues for a stimulus category. The Approach-Avoidance Task (AAT)is a computerized program in which participants make approach or avoidance movements in response to an irrelevant feature of an image presented on a computer screen (e.g., push when in portrait, pull when in landscape). The intervention in this study is a treatment version of the AAT used as an Approach Bias Modification (ABM) intervention, to retrain participants' implicit biases toward or away from stimuli by presenting the target stimuli predominantly in one format (e.g., push or pull).
