Common constraints limit Korean and English character recognition in peripheral vision
Journal of Vision, 18(1).
Contributors: * , M. Kwon* & G. Legge *
author keywords: visual span; reading; pattern complexity; pattern recognition; crowding
MeSH headings : Crowding; Female; Humans; Korea; Language; Male; Multilingualism; Pattern Recognition, Visual / physiology; Psychophysics; Reading; Visual Perception / physiology; Young Adult
TL;DR:
The transfer of training from Korean to English characters for a group of bilingual Korean native speakers showed that the visual span is limited by common sensory (crowding) and physical (pattern complexity) factors regardless of the language script, providing evidence that theVisual span reflects a universal bottleneck for text recognition.

Korean reading speed
Vision Research, 150, 8–14.
author keywords: Reading; Peripheral vision; Age-related macular degeneration; Low vision; Crowding
MeSH headings : Adolescent; Adult; Female; Humans; Language; Male; Mass Media; Reading; Republic of Korea; Retina / physiology; Size Perception / physiology; Young Adult
TL;DR:
Korean reading speed is more affected by retinal eccentricity than English, likely due to additional within‐character crowding from more complex orthography, and may experience more difficulty than English readers.

Contributors: * & G. Legge *
MeSH headings : Female; Humans; Male; Pattern Recognition, Visual / physiology; Psychophysics / methods; Reading; Visual Fields / physiology; Young Adult
TL;DR:
It is found that distributed training, but not the presence of flankers, appears to be necessary for the training benefit to transfer to increased reading speed, and the association between crowding, visual span, and reading is clarified.

MeSH headings : Adolescent; Adult; Aged; Aged, 80 and over; Aging / physiology; Child; Contrast Sensitivity / physiology; Female; Humans; Male; Middle Aged; Reading; Sex Characteristics; Vision Tests; Vision, Ocular / physiology; Young Adult
TL;DR:
A weak dependence of the MNREAD parameters on age in normal vision is found, and in broad terms, MNREAD performance exhibits differences between three age groups: children 8 to 16 years, young adults 16 to 40 years, and middle-aged to older adults >40 years.

Journal of Vision, 15(8).
author keywords: face recognition; letter recognition; visual span; crowding; visual acuity
MeSH headings : Facial Recognition / physiology; Female; Fixation, Ocular / physiology; Humans; Male; Pattern Recognition, Visual / physiology; Psychophysics; Reading
TL;DR:
The findings show that the visual span for faces is smaller than that for letters, however, when differences in first-stage processing for letters and faces are accounted for, the two visual spans become nearly identical.

Sensory and cognitive influences on the training-related improvement of reading speed in peripheral vision
Journal of Vision, 13(7).
TL;DR:
This work derived the temporal attenuation characteristics of the early (prenonlinearity) and late (post-non linearity) stages of the L- and M-cone pathway that signals brightness and found that the early stage acts like a band-pass filter peaking at 10-15 Hz with sensitivity losses at both lower and higher frequencies, whereas the late stage actslike a two-stage low-pass Filter with a corner frequency near 3 Hz.
