How might speech production errors affect spelling performance?
The limited data available that address this issue suggest that articulation errors errors (i.e., non-phonologically based speech errors) do not carry over into spelling. For the children who have been studied, it does not appear that their speech production is represented in their internal representation of the word. It is possible, however, that the spellings of students who are spelling phonetically may be affected by their misarticulation of sounds. In contrast, children who have phonologically based speech errors (i.e., speech errors in the absence of any other significant physical, sensory, or cognitive impairment) demonstrate poor performance on spelling tasks (Carroll & Snowling, 2004) due to poorly specific phonological representations of words stored in long term memory and/or difficulty accessing the internal phonological representations (Sutherland & Gillon, 2005).
