Talking to oneself out loud—known in psychology as “self-talk” or “thinking out loud”—is a common and beneficial behavior, not a sign of irrationality. Rather than indicating madness or social isolation, self-talk serves as a powerful cognitive tool with a range of psychological benefits. Gary Lupyan, associate professor of psychology at the University of Wisconsin, explains that this practice can improve memory and concentration, challenging the stereotype that talking to oneself is a symptom of instability.
In one experiment, participants who named objects out loud were able to locate them more quickly than those who remained silent. As Lupyan explains, “Even though we all know what a banana looks like, saying the word out loud helps the brain activate additional information about that item, including what it looks like.” Verbalizing names or thoughts engages both visual and contextual processing in the brain, enhancing identification and recall.
