Micro-incentives refers to small rewards, typically frequent and cash-based, given out on a per-behavior basis. A prominent example is Wellth, a program for people with chronic illness delivered via app. Some participants are given around $2 each time they take a medication or measure their blood pressure and submit a photo. In related studies, e.g. Petry et al. (2015), participants' compliance with these behaviors was significantly higher than those who did not receive the incentives, and the behaviors persisted several months after incentives were removed. Micro-incentives can be layered with other reward approaches such as lotteries and non-financial incentives.

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).

Financial incentives are monetary rewards given for performing a certain behavior. These come in many different varieties; for example, they may be guaranteed vs lottery-based, or group-oriented vs individually-assigned.

Lotteries are any form of assigning an award where there is an element of randomness or chance.One example is a prize-linked savings account (PLSAs). One of the earliest of these was the Million a Month Account (MAMA) in South Africa, where First National Bank offered account-holders with qualifying deposits a chance to win up to one million rand each month (along with other smaller prizes given out at random). Lotteries may be used with non-financial rewards as well, e.g. offering tickets to a sold-out play or sporting event for employees reaching certain performance benchmarks.

Changing the consequence of a behavior is one way to influence it. Rewards and incentives constitute positive reinforcement—the addition of a desired stimulus following the successful performance of a behavior. These may be monetary or non-monetary.

Behavioral economics is the exploration of how people make consequential decisions where psychological and sociological factors may influence the outcome or process. It is often considered the fusion of economics and psychology (which itself was an interdisciplinary field entailing medicine and philosophy). The exploration of psychological factors in economic decision-making, including deviation from rationality, traces well back to classical and neoclassical economics (i.e. Gabriel Tarde, Wilfredo Pareto, and John Maynard Keynes) and prior to psychology becoming a formal discipline. Behavioral economics is often associated with behavior change tactics like smart defaults, reducing friction or barriers, increasing salience, incentives, active choice, and commitment devices.‍
