In children, two types of phonological U errors" may occur: slips of the tongue\ud
and pathological speech. A slip of the tongue is considered a normal, nonsystematic\ud
U error", whereas a series of consistent speech U errors" is labeled as a\ud
speech pathology. Both types of U errors" follow phonotactic constraints defined\ud
by the target grammar, and may result in substitutions and omissions of sounds\ud
in conversation. They differ traditionally in two key ways: (1) while slips are\ud
unique utterances that generally occur only once, the disfluencies are consistent\ud
in a pathology, and (2) the speaker is able to notice and correct their error when\ud
they make a slip, but it is not the case in a speech pathology. Relevant research to\ud
both types of U errors" will be presented for comparison purposes, and theoretical\ud
explanations will be offered. I will propose that a deficit in self-monitoring exists\ud
in those with disordered phonology, in order to explain why U errors" repeat
