Aboriginal Education Office in association with:
Ministry of Education
Ministry of Training, Colleges and Universities
Rationale for Study
Canadian Institutes of Health Report “Literacy and Health in Canada” – Aboriginal peoples in Canada have lower reading literacy scores than non-Aboriginal Canadians
1988 needs survey by M’Chigeeng First Nation – critical to establish a community based literacy program due to high rate of residents without a high school diploma
Rationale for Study
Elkind, Black, and Murray (1996) in a study of adults with reading disabilities demonstrated enhanced performance in reading speed and reading endurance when using text reading software as compared to reading unaided.
Higgins and Raskind (1997) in a study of post-secondary students with dyslexia found that disabled readers improved reading comprehension scores when utilizing text reading software.
Methodological Shortcomings
An exhaustive literature search revealed that there is a dearth of studies investigating the effects of text reading software on reading skills in Aboriginal populations.
Research Questions
Examine the efficacy of text-to-voice technology on reading comprehension performance in an Aboriginal population with self-reported reading difficulties.
Identify the cognitive correlates associated with improved reading comprehension utilizing reading technology for an Aboriginal population with self-reported reading difficulties.
Research Sample
38 Aboriginal participants with self-identified reading difficulties
Wikwemikong First Nation n = 31, M’Chigeeng First Nation (West Bay) n = 7
Mean age = 30.05 years (SD = 12.02) Mean grade level completed = 10.66 (SD = 1.83) Sex Ratio = 22 males, 16 females
Procedures
Each participant completed a variety of cognitive and reading assessments.
Participants received a training session using assistive reading technology (proficiency with software controlled)
Counterbalanced format – all participants completed reading comprehension pre and post testing with and without the use of assistive technology.
Measurements
Questionnaires:
Adult Reading History Questionnaire – Revised (Parrila, Corkett, Kirby, & Hein, 2003).
Author Recognition Test (West, Stanovich, & Mitchell, 1993).
Computer Attitude Questionnaire (Knezek & Miyashita, 1993).
Adult Reading History Questionnaire – Revised (ARHQ-R)
Author Recognition Test
Abbreviated Author Recognition Test
Instructions: Below you will see a list of 25 names. Some of the people in the list are popular writers (of books, magazine articles, and/or newspaper columns) and some are not. Please read the names and circle those individuals who you know to be writers. Do not guess, only circle those who you know are authors.

Research Findings
2. Overall, participants provided more correct answers and attempted more questions on the comprehension component of the ND when reading without assistive technology; number of incorrect answers remained constant when reading with and without assistive technology
confounds = lack of computer experience *, computer anxiety*, reading exposure (ART**), automaticity concerns ( e.g., processing speed*).
** significant at the 0.01 level (two-tailed); * 0.05 level (two-tailed)

Research Findings
3. Students with a given set of cognitive characteristics, poor performance on non-word repetition and rapid naming tasks, demonstrated improvements in comprehension on the Nelson Denny when using assistive technology

Significance of Nonword Repetition to Reading Comprehension utilizing AT
Assesses many of the underlying skills associated with utilizing assistive technology for reading comprehension.
1. Sound Perception – acoustic quality and phonotactic frequency (Coady et al., 2005, 2007)
2. Phonological Awareness and Processing – processing of phonemes (Bowery, 1996)
3. Phonological Memory –the ability the store phonological units (i.e., phonemes); associated with depth of vocabulary (verbal comprehension)
Cognitive Load Theory (Sweller, 1999) and Nonword Repetition Performance
Poor NWR performance
Good NWR performance
Deficits in processing
mechanisms underlying

Have prerequisite NWR skills
Congruent with AT
instructional format
Incongruent with AT
instructional format
Intrinsic processing + instructional format = germane cognitive load
(reading comp. gains)
Intrinsic processing + instructional format = high cognitive load (expertise reversal effect)
AT - Highly structured, word-by-word reading format
Applications/Future Research
1. ARHQ-R predicted general reading difficulties in the sampled population; it holds merit as a screening tool to discern reading problems in Aboriginal adults.
2. Examining students’ phonological processing profiles prior to assigning reading technology may be a useful practice if similar results are found in a larger research sample.
3. Future studies: follow-up study with participants utilizing technology for a longer period of time.
