This is the reason, according to psychology, why some people repeat sentences a lot.

According to psychology, people who tend to repeat phrases might use this method to process and clarify your thoughts. By verbalizing an idea repeatedly, they regain confidence in their own speech and ensure that the information is clear to themselves and those around them. This behavior can also serve to memorize and structure information more efficiently, thus facilitating its assimilation.

In some contexts, repetition may be related to seeking external validation. People who feel unsure of their ideas or have low self-esteem may use repetition to seek confirmation from their interlocutors. By repeating phrases, they hope to receive responses that validate their thoughts, which provides them with a feeling of safety and acceptance.

Moreover, this behavior is not limited to psychological problems alone. In some cases, repetition may be linked to neurological or cognitive disorderswhere repetition is a symptom of disorders such as obsessive-compulsive disorder (OCD) or autism spectrum disorder. In these cases, repetition is not a simple communication strategy, but a manifestation of more complex internal processes.
