Self-talk isn’t just motivational messages like “You can do it!” or “Almost there,” although this internal cheering section can give us confidence. A review of more than two dozen studies, published last year in the journal Perspectives on Psychological Science, found that there’s another kind of mental message that is even more useful, called “instructional self-talk.” This is the kind of running commentary we engage in when we’re carrying out a difficult task, especially one that’s unfamiliar to us. Think about when you were first learning to drive. Your self-talk might have gone something like this: “Foot on the gas pedal, hands on the wheel, slow down for the curve here, now put your blinker on…”

Over time, of course, giving yourself instructions becomes unnecessary — but while you’re learning, it does three important things. First, it enhances our attention, focusing us on the important elements of the task and screening out distractions. Second, it helps us regulate our effort and make decisions about what to do, how to do it, and when. And third, self-talk allows us to control our cognitive and emotional reactions, steadying us so we stay on task.
