Seven sentences were chosen for the copy typing task (presented in Figure 2). Sentence one is an English language pangram, i.e., it contains all the letters of the English alphabet, and is traditionally used to evaluate typing performance (e.g. Silfverberg et al., 2000). Sentences 2–4 are common English phrases that were easy for the participants to remember. Sentence five is the beginning of the ‘Rainbow Passage,’ commonly used in the speech pathology field to evaluate speech quality/deficits ([Fairbanks, 1960], pp. 124–139). Sentences 6 and 7 are conversational and were chosen to simulate the types of phrases an assistive communication device might be used to type in a conversation.
