What characteristic of psychogenic stuttering differentiates it from developmental stuttering?

Psychogenic stuttering is primarily characterized by the individual's awareness of their stuttering, which allows them to understand and recognize their speech difficulties. This awareness often leads to a higher level of anxiety or concern about their speech, distinguishing it from developmental stuttering, where the individual may be less aware of their speech disruptions. While developmental stuttering can also involve repetition of syllables and sometimes accompanying physical tension or grimaces, the key difference lies in the awareness and psychological factors associated with psychogenic stuttering. Individuals with psychogenic stuttering may experience greater emotional responses and may alter their speech behaviors based on their awareness of what is happening, which can lead to variabilities in their speech patterns under different circumstances.
