Reading is vital to every aspect of modern life, exacerbated by reliance of the internet, email, and social media on the written medium. During reading, letters comprising a word are recognised, combined, and converted into meaning and sound. Letter confusability refers to how visually similar different letters are to each other (“v-w” is more confusable than “v-l”). Confusability affects readability, as observed in reading errors and processing speed of dyslexic individuals.
This research depends on confusability ratings between a target letter and other letters of the alphabet, and current resources are insufficient.
This project will: (1) develop confusion matrices that precisely capture letter similarity for lower and upper case; (2) use visual distortion to filter out attributes critical in letter processing to test which letters are susceptible to confusion.
These matrices will constitute a valuable new resource for studies in letter perception and reading processes in skilled and dyslexic readers.
Meet the Principal Investigator(s) for the project
Dr Daniel Roberts - Dr. Roberts is a Senior Lecturer in Cognitive Neuroscience.
Dr. Roberts investigates the neurocognitive basis of visual recognition, how this links to language processing, and how these processes become disrupted (e.g., word, object, and face recognition). He uses a multimethod approach including cross-population neuropsychological behavioural studies (brain-damaged, developmentally disordered, neurologically intact), neuroimaging, awake craniotomy, brain stimulation, and visual psychophysics. His research aims to advance our understanding of (1) the patterns of impairment congenitally and/or after brain damage; (2) typical cognition and decline (e.g., healthy ageing); (3) neurocognitive principles that guide rehabilitation in clinical practice (e.g., new diagnostic tools, interventions).
