Abstract: In an embodiment, a method implemented by one or more processors, comprising: receiving one or more recordings of one or more consequences of one or more of activity or inactivity of a user related to a predetermined goal; determining that an opportunity for the user to engage in, or refrain from, a subsequent activity that will affect progression of the predetermined goal is present; and triggering a playback of the one or more recordings to the user based on the determined opportunity.

Abstract: In an embodiment, a computer-implemented method, comprising: receiving contextual information for a user; updating a user state based on the received contextual information; providing electronic interventions to the user over a first interval by executing a first intervention algorithm based on the updated user state; and providing electronic interventions to the user over a second interval based on executing a second intervention algorithm that maximizes a reward function based on a further updated user state of the user and the electronic interventions of the first interval, the second intervention algorithm of a different type than the first intervention algorithm.
