New insights into the role of motion and form vision in neurodevelopmental disorders (2017)
Journal Article
Johnston, R., Pitchford, N. J., Roach, N. W., & Ledgeway, T. (2017). New insights into the role of motion and form vision in neurodevelopmental disorders. Neuroscience and Biobehavioral Reviews, 83, https://doi.org/10.1016/j.neubiorev.2017.09.031

A selective deficit in processing the global (overall) motion, but not form, of spatially extensive objects in the visual scene is frequently associated with several neurodevelopmental disorders, including preterm birth. Existing theories that propos... Read More about New insights into the role of motion and form vision in neurodevelopmental disorders.

Visual perception in dyslexia is limited by sub-optimal scale selection (2017)
Journal Article
Johnston, R., Pitchford, N. J., Roach, N. W., & Ledgeway, T. (in press). Visual perception in dyslexia is limited by sub-optimal scale selection. Scientific Reports, 7, Article 6593. https://doi.org/10.1038/s41598-017-06967-6

Readers with dyslexia are purported to have a selective visual impairment but the underlying nature of the deficit remains elusive. Here, we used a combination of behavioural psychophysics and biologically-motivated computational modeling to investig...

Encoding of rapid time-varying information is impaired in poor readers (2017)
Journal Article
Johnston, R., Pitchford, N. J., Roach, N. W., & Ledgeway, T. (2017). Encoding of rapid time-varying information is impaired in poor readers. Journal of Vision, 17(5), Article 1. https://doi.org/10.1167/17.5.1

A characteristic set of eye movements and fixations are made during reading, so the position of words on the retinae is constantly being updated. Effective decoding of print requires this temporal stream of visual information to be segmented or parse... Read More about Encoding of rapid time-varying information is impaired in poor readers.

GreekLex 2: a comprehensive lexical database with part-of-speech, syllabic, phonological, and stress information (2017)
Journal Article
Kyparissiadis, A., van Heuven, W. J., Pitchford, N. J., & Ledgeway, T. (2017). GreekLex 2: a comprehensive lexical database with part-of-speech, syllabic, phonological, and stress information. PLoS ONE, 12(2), Article e0172493. https://doi.org/10.1371/journal.pone.0172493

Databases containing lexical properties on any given orthography are crucial for psycholinguistic research. In the last ten years, a number of lexical databases have been developed for Greek. However, these lack important part-of-speech information.... Read More about GreekLex 2: a comprehensive lexical database with part-of-speech, syllabic, phonological, and stress information.
