At some point you have probably caught yourself narrating your grocery run, coaching yourself through a parking situation, or whispering “okay, where did I put it” as you retrace your steps through the kitchen. And then, almost immediately, you’ve looked around to make sure nobody heard you. Because somewhere along the way, we all got the message that talking to yourself is a little bit off. Turns out, psychology has been quietly building the case that not only is this behavior completely normal, it might actually be making your brain work better.
The science behind the monologue
One of the more interesting places to start is with research out of Bangor University in the UK. Psychologist Paloma Mari-Beffa and her colleague Alexander Kirkham ran a study published in Acta Psychologica where they gave participants a set of written instructions and then asked them to read those instructions either silently or out loud before completing a task. The researchers found that talking out loud actually improved participants’ control over a task compared to what’s achieved by inner speech alone, with much of that benefit appearing to come simply from hearing oneself, since an auditory command seems to better control behavior than a written one. So the next time you read a confusing set of instructions out loud before assembling something, you’re not being weird. You’re running a cognitive efficiency protocol your brain already knows how to use.
Your brain uses sound as a shortcut
Gary Lupyan and Daniel Swingley took this a step further with a study that’s genuinely hard to argue with. Published in the Quarterly Journal of Experimental Psychology, the research was inspired by observations that people often audibly mutter to themselves when trying to find something, like a jar of peanut butter on a supermarket shelf. They set up a visual search task where participants had to find objects from a set of pictures. Some searched in silence. Others were asked to say the name of the object they were looking for out loud as they searched. Speaking facilitated search, particularly when there was a strong association between the name and the visual target, suggesting that verbal labels can actively change ongoing perceptual processing, making the visual system temporarily better tuned to whatever you’re looking for. Put simply, saying “keys, keys, keys” while you tear apart your bag isn’t a sign you’re losing it. It’s your brain using language to sharpen what your eyes are doing. Full study here:
We were born doing this
Here’s the thing that rarely makes it into the conversation about self-talk: we didn’t develop this habit as adults under stress. We were born with it. Developmental psychologist Lev Vygotsky was one of the first to seriously study what he called “private speech,” the out-loud narration children do while playing or working through problems. Private speech is typically observed in children from about two to seven years old and serves as a tool for communication, self-guidance, and the regulation of behavior. Vygotsky maintained that children’s private speech is used for self-direction and that this language is the foundation for later complex mental activity. And critically, researchers have noted a positive correlation between children’s use of private speech and their task performance and achievement, with private speech decreasing and “going underground” as children begin school.
What kind of self-talk actually helps
Not all self-talk is created equal, and that’s worth knowing. The running commentary of “I’m terrible at this” or “I always mess things up” is technically still self-talk, but it doesn’t carry the same cognitive benefits. Research consistently makes a distinction between instructional self-talk, where you’re talking yourself through a task step by step, and motivational self-talk, which is more about encouragement and emotional regulation. Positive self-talk may decrease anxiety and improve concentration and focus, while negative self-talk, though it might increase motivation in certain contexts like sport, doesn’t reliably improve actual performance.There’s also something interesting about using your own name. Studies suggest that referring to yourself in the third person, like saying “okay, you can do this” rather than “okay, I can do this,” creates just enough psychological distance to help you think more clearly under pressure. It sounds strange but it works because your brain processes it more like advice from someone else, which we tend to follow more readily than our own instincts.
Why we’re so embarrassed by it
The stigma around self-talk is pretty disproportionate to what the behavior actually involves. Most people who get caught mid-monologue feel a wave of embarrassment that’s completely out of sync with the reality that everyone does some version of this. The cultural assumption that talking to yourself signals instability is old and not especially evidence-based. Self-talk can be a practical and accessible strategy for managing everyday challenges, which is a pretty underwhelming way to describe something that cognitive research keeps showing has real, measurable effects on how well people perform and how clearly they think.So if you’ve been quietly apologizing for your solo kitchen commentary or the pep talk you gave yourself in the car this morning, maybe let that go. Your brain wasn’t misfiring. It was doing exactly what it’s built to do.
