Did you think that cluttering is just a speech disorder? Well, it is not. The characteristics of cluttering can be found not only in the speech, like in the core symptoms or secondary symptoms, but also in other “channels” of communication. We call them general symptoms in cluttering. Deso Weiss, one of the first to research cluttering, describes it as a problem with “language” in the broadest sense. His theory is that cluttering originates from what he calls a “central language imbalance“. According to him, symptoms of cluttering are often present in other communication channels as well, like in thinking (language), listening (picking up on and interpreting signals), looking (making eye contact), acting (body language and posture), and writing (handwriting). Sometimes the reading comprehension of clutterers is also affected.
