Abstract— Student diversity in higher education tends to
focus on gender, ethnicity/race, and socio-economic status.
However, these factors do not address cognitive diversity.
Cognitive diversity, within the context of this study, refers to the
varying ability of brain functions such as reasoning and memory,
excluding persons with a developmental disability. Students with
learning disabilities (LD), specifically dyslexia, contribute to this
cognitive diversity. This study aims to initiate scholarly research
on academic success factors for First-Year Engineering (FYE)
students with dyslexia. FYE student performances on the
Purdue Spatial Visualization Test-Rotations (PSVT-R) and
Student Attitudinal Success Instrument (SASI) have been found
to be predictors of academic success in engineering. A
preliminary analysis of entering FYE student performance on the
PSVT-R and SASI is conducted for three populations: students
with dyslexia, students with a LD, and students without a LD.
The anticipated findings will support the inclusion of cognitive
ability, with an emphasis on LD and dyslexia, in FYE engineering
diversity programs.

I. INTRODUCTION
This work-in-progress (WIP) paper presents preliminary
findings from a quantitative study designed to investigate
critical factors influencing academic success of engineering
students with dyslexia. “Dyslexia is a specific learning
disability that is neurological in origin. It is characterized by
difficulties with accurate and/or fluent word recognition and
by poor spelling and decoding abilities. These difficulties
typically result from a deficit in the phonological component
of language that is often unexpected in relation to other
cognitive abilities and the provision of effective classroom
instruction. Secondary consequences may include problems in
reading comprehension and reduced reading experience that
can impede growth of vocabulary and background
knowledge” [1]. This study examines spatial abilities and
attitudes toward formal learning experiences. Comparisons are
made between First-Year Engineering (FYE) students with
dyslexia, a learning disability (LD), and students without a LD
on the Purdue Spatial Visualization Test-Rotations (PSVT-R)
and the Student Attitudinal Success Instrument (SASI). The
PSVT-R is amongst the most common instruments for
assessing visual spatial skills of engineering students [2]. It
requires the student to visually rotate a solid to the correct
position [3]. The SASI is a 161-item survey that is composed
of 13 specific attitudinal and affective constructs, which have
evidence of validity and reliability for engineering students
[4]. The SASI is used to assess these constructs prior to the
first year of engineering study and assists with retention
programs and efforts at the first-year level.
II. DYSLEXIA & ENGINEERING
A. Disabilities in Engineering
The National Academy of Engineering (NAE) has released
several reports stating the U.S. must increase the diversity of
engineers to meet the competitive need in the field [5][6]. Yet,
this characterization of engineering diversity must be furthered
to explicitly identify persons with different cognitive abilities
such as a LD. The National Science Foundation (NSF)
Committee on Equal Opportunities in Science and Engineering
(CEOSE) supports the advancement of people with disabilities
in STEM disciplines with the purpose of supporting diversity,
however, LDs are not a major focus and data is not readily
available. LDs are a major component of cognitive diversity,
the varying ability of brain functions, such as reasoning,
memory, and perception [7][8][9], and must be included in this
national dialogue. The CEOSE has recently noted a need to
regularly collect data on disabilities in STEM and requested
that the National Center for Science and Engineering Statistics
(NCSES) move forward with this recommendation [10].
B. Students with Dyslexia: Self Perception
Currently, there is minimal research explicitly
investigating undergraduate engineering students with
dyslexia. Research has found that history of academic
achievement and stress impacts the self-perceptions of
students with a LD or dyslexia in higher education [11][12].
These stress factors also persist in students that have both
dyslexia and gifted abilities, referred to as twice-exceptional
[13]. Twice-exceptional students with dyslexia are often
identified late in their academic career; these students may be
of particular interest to engineering. For example, competitive
