See [this ](https://i.imgur.com/1wgPP6G.png)image link. Great comment! I agree that "fear" (as you pointed out) can be conditioned to a speech block-response (such as, fear to speak our name can cause a 5 second block for some of us, right?). But if we only focus on the negative emotions, then we overlook the other (neutral/positive) emotions, see [this ](https://i.imgur.com/1wgPP6G.png)research model (I created this screenshot in MSpaint). Watch closely to the image of the dog (in the screenshot). The "bell" ringing can be associated with a positive emotion (which the dog perceives).. in the same way, every stutter experience that we face changes us often without us even noticing.. whether it's an experience from positive or negative emotions, and this also changes our stuttering behavior. Yes indeed, we will likely stutter more severely if we fear certain words or situations.. but "conditioned" triggers, such as, ***positive or neutral*** *emotions, thoughts, sensations, experiences or any other trigger* also affects stuttering. Because we don't ONLY stutter on feared words, we can also stutter on all the other non-anticipated words, or when we are alone (yes most of us stutter significantly less or don't stutter when alone, but still sometimes we do stutter.. you get my point.. on Reddit we often only hawk-gaze at negative emotions that we overlook the other non-negative triggers). For example, just perceiving an image of ourselves stuttering or viewing ourselves as a person who stutters, in my opinion, might create many unnoticeable triggers (that trigger stuttering), not to mention that it might create anticipation (aka anticipatory triggers).
