Assessment of anomia: Improving efficiency and utility
Gerasimos Fergadiotis, PhD., CCC-SLP
Portland State University

Anomia is a core feature of aphasia, a disorder affecting at least 2.5 million
Americans. Sensitive metrics are needed to support investigations of the
cognitive mechanisms underlying anomia, clinical decision making, and
treatment research. To be optimally useful, these metrics must be validated
within a rigorous psychometric framework to (i) efficiently provide
information about a patient’s overall severity, (ii) support repeated
assessments without threatening internal validity or measurement precision,
(iii) be easily integrated into computerized adaptive testing platforms, and
(iv) reliably categorize paraphasias in order to shed light to patients’
cognitive-linguistic deficits. To this end, I will discuss two distinct yet
highly related lines of research. First, I will focus on our efforts to
engineer a psychometrically robust computer adaptive anomia test within an
item response theory framework. Second, I will present some successes and some
challenges in using natural language processing techniques to algorithmically
classify paraphasias.
