How is cluttering primarily characterized?

Cluttering is primarily characterized by rapid and often irregular speech patterns that can result in disorganized formulation of language. Individuals who clutter may speak at a speed that is difficult for listeners to follow, and their speech can be marked by a lack of coherence, making it challenging for both the speaker and the listener to understand the intended message. This disorganization may manifest through a jumble of words and phrases, where thoughts are expressed in a hurried manner, often leading to incomplete thoughts or difficulties in organizing sentences logically.

In contrast, the other options highlight characteristics associated with different speech disorders. Extended blocks and prolonged syllables are more aligned with stuttering rather than cluttering. Frequent use of interjections, while it can occur in cluttering, is not the primary defining feature. Likewise, awareness of speech errors is typically seen in individuals who stutter; those who clutter often exhibit less awareness of their speech disorganization. Thus, the first option accurately captures the essence of cluttering as a speech disorder.
