>*The next day i had to read instructions out loud for 5 seconds and i couldnt get the words out. why does this happen? any thoughts?* One possible answer could be, see [this](https://i.imgur.com/9lYPWrt.png) screenshot([1](https://go.gale.com/ps/i.do?p=AONE&u=googlescholar&id=GALE|A535816584&v=2.1&it=r&sid=AONE&asid=52bf60f0)).. to translate it in simple words: * For example, two stimuli have resulted in a conditioned response, such that, when you are in class reading aloud, you have associated "reading instructions for 5 seconds" + stuttering with a negative outcome, so basically a trigger leads to inhibiting execution of speech motor plans * For example, attention of heightened demands - to execute speech motor plans - follows intention * For example, reinforcing overreliance on a pressure in your throat (or other physiological arousal), or reacting to it - during reading in class * For example, immersing oneself in negative experiences - during reading in class - leading to lack of confidence/faith in your ability to execute speech motor plans * For example, a negative evaluation of your ability to execute speech motor plans - during reading in class, resulted in (1) giving up on the feedforward system, and replaced it with excessive overreliance on the production of feedback system, or (2) replacing the internal with an external speech motor timing cue, or (3) implementing avoidance or safety behaviors to avoid the initial speech plan (aka stuttering), or (4) an easy, normal disfluency becomes paired with an event (in this case, reading aloud) that makes you lose faith in the feedforward system, or (5) when reading aloud, you did something on purpose to get out or "escape" from the stutter, such as head jerking or blinking your eye, creating perceived conflict, excessive monitoring and perceiving increased speech errors (that behavior is now conditioned to stop a stutter in one's head (Operant Conditioning) As homework, you could google the [execution of speech motor plans](https://www.google.com/search?q=%22speech+motor+plans%22+%22stuttering%22), and classical conditioning. Note, remember that a conditioned response doesn't necessarily have to come from fear.. simply visually seeing an interesting book (positive stimulus) or the need to read (neutral stimulus), can evoke a conditioned response resulting in stuttering.
