It's a way of taxonomical categorizing how one uses conditionings, a process in which a previously neutral stimulus comes to evoke a specific response by being repeatedly paired with another stimulus that evokes the response either consciously or subconsciously. In your experience, how did you consciously or subconsciously trigger those responses to stop stuttering when you are alone or talk to yourself? (for example you can respond with: 2A, B, D, G)
