In Gayle DeDe’s (2017) study, they explored silent reading comprehension in individuals with Aphasia. Word frequency, word class, and word length were the three variables that were investigated in order to examine how these variables contribute to time course of silent reading in individuals with aphasia. DeDe previously conducted similar studies regarding reading comprehension in individuals with Aphasia. In 2012, DeDe found that individuals with Aphasia showed longer reading time and listening time for low frequency words than the controls. In 2013, DeDe focused on syntactic complexity and its effects on reading and listening times. Both the control group and the group with Aphasia showed longer reading and listening times for complex sentences.

Gaze duration was the total duration of all fixations on a word before moving eyes to another word. Skipping rate indicated whether the reader fixates on a given word on their first pass through a sentence. Words are more likely to be skipped when they are short, highly predictable in the context, or function words. Fixations were defined using the manufacturer’s default settings which used an algorithm. Gaze duration and rereading duration were based only on fixations. Sentences were excluded if a participant blinked while reading a vital word, which resulted in the removal of 11% of the sentences. Each of the four dependent measures was estimated separately for each of the variables mentioned …show more content…
Interestingly, there was no significant effect of word frequency in first fixation duration. However, gaze durations and rereading times indicated that the effects of word frequency were greater in individuals with aphasia. Individuals with aphasia had a greater reading time than controls for all word lengths and frequencies. First fixation duration, gaze duration, and rereading times were also longer in individuals with aphasia. Both groups showed higher skipping rates for determiners than high frequency nouns but individuals with aphasia skipped fewer nouns and determiners compared to the
