Implementation intentions are specific details for when and how a behavior should or will be performed. These are often formulated as ""if-then"" rules, such as:- "if I crave something sweet, I'll have fruit instead of candy"- "if I am in the mood for a cigarette, I'll wait 5 minutes—then, if I still want it, I can have one"Other examples include studies where flu vaccination uptake was higher in groups of people nudged to make more specific plans (i.e. picking a specific time and date, along with a mode of transport to a specific clinic). The same general effect was observed with voting behaviors. These are a generally low-cost tool to slightly improve the gap between intention and performance of a behavior.

Education refers to empowering a person with more knowledge or training than they had previously. While providing information alone is often a suboptimal way to drive meaningful behavior change or long-term interventions, the right message at the right time can be a powerful part of a behavior change strategy.‍

Reminders, cues, and prompts are simply methods to cause someone to perform a behavior by calling their attention to it with a timely message. People have limited attention and memory, so these types of influences can be very effective when done skillfully. The cue need not consist of written or spoken language; for example, it could be a certain melody, symbol, or pattern of lights on a connected home device. It might also be a bracelet or pattern of vibrations from a wearable device. Provided the cue or prompt is associated with the behavior, almost any sensory stimuli that is reliably perceived and interpreted may be used. That said, verbal reminders can be effective since they may be personalized with additional semantic information related to the person's context or leverage other effects (e.g. identity priming or framing effects).

Behavior substitution refers to attempting to eliminate a problematic behavior by replacing it with another one. Often, the substituted behaviors are intended to have similar sensory qualities (e.g. drink flavored sparkling water instead of soda). The goal is typically to disassociate the original behavior from its cue, enabling the more positive behavior to be triggered automatically.‍

Tracking cognitions or emotions (often both) refers to a person recording when they have certain thoughts or feelings. The person might note every time they experience a given thought or specific feeling whenever it comes up, or alternatively simply keep a diary of any notable thoughts or feeling at pre-determined times. Often, this also includes noting what triggered or occured before or alongside these thoughts and emotions. Many therapuetic approaches utilize this tool, even if only for brief periods, to help a system, clinician, or patient better understand the patterns around their thoughts and feelings. Often, this data is integrated into additional behavior change approaches, like behavioral activation or implementation intentions.
