Why Our Brain Can’t Help but Interrupt in a Conversation
Speaking and listening are two actions that are rarely fully executed at the same time. According to neuropsychologist Catherine Pierrat, cited by Psychologies, the human brain processes language, anticipates responses, and seeks to connect what is heard with memories and emotions even before the other person finishes speaking. “The desire to participate, not to miss the moment, or to share something personal can lead us to speak over others without realizing it,” explains the French specialist.
The Brain That Never Stops
While other brain areas assess the relevance of what is heard and prepare a response. This multitasking turns interruption into an almost automatic reaction, more common in impulsive people or under stress. Pierrat points out that working memory – that “mental notepad” that retains short-term information – also influences: when we believe that an idea could fade away, we feel the need to say it right away.
Emotion, Culture, and Social Bond
Interruption is not always aggressive. In familiar or trusting environments, overlapping speech turns are seen as natural dialogue; in formal or hierarchical contexts, it is perceived as disrespectful. Social and cultural norms make differences: in some cultures, overlapping speech turns are considered part of natural dialogue; in others, speaking over others is considered impolite. In any case, the form and intention weigh as much as the moment. Interrupting someone who already feels unheard – women, young people, or newcomers to a group – can amplify the feeling of exclusion and undermine trust.
