Stuttering

Myth: I usually have trouble saying my name and phone number when people ask. However, I can say them fluently if I'm alone. This is evidence that stuttering is psychological.

Reality: This effect can be explained by three factors. First, stuttering is a disorder of spontaneous speech, it means that it tends to manifest with greater intensity when speech is used in propositional manner, ie, when the speech actually has practical purpose. Speaking a phrase out of context (when one is alone, for example) decreases propositionality that expression, causing stuttering also decrease. Second, in the actual context, there is a time pressure natural, ie the expression is to be rendered at the proper time. Recalling that the difficulty of temporalization is precisely the most difficult of people who stutter, it's no wonder that the difficulty increases when the time pressure is present. Third, if the person react negatively against the anticipation of the occurrence of stuttering, stuttering also more likely to occur due to activation of the freeze response, which causes the body tends to shut down, thus changing the production of speech. Remember that many other disorders vary according to the situation (eg, Tourette syndrome, spasmodic dysphonia, Parkinson's disease) and this is not an exclusive feature of stuttering.
