Introduction: The Newborn Acuity Cards (NAC) have been used on neonates and were noted to be simple, fast, and reliable. The distinguishing features of NAC include central placement of the gratings and wide range of grating acuity that can be measured. In the current study, NAC were used with children who had developmental delays to determine the…

This work examines the influence of clutter when presenting information with a head-mounted display (HMD). We compare clutter costs when displays overlay a real-world scene to the costs of visual scanning required when displays are presented separately. Using an HMD in safety-critical environments reduces repetitive visual scanning and head…

Understanding of preterm infant cognitive competences across the first year of life is limited regarding the developmental constructs of continuity, stability, coherence, and predictive validity as well as how they manifest by age and country of origin. This prospective longitudinal study examined and compared mean-level continuity,…

This study explored cognitive effects on narrative macrostructure in both languages of 38 Russian-German bilinguals aged 4;6 to 5;1‚ while controlling for demographic factors (sex, socioeconomic status) and language proficiency. Macrostructure was operationalised as story structure (SS) and story complexity (SC) using the Multilingual Assessment…

This study examined the difference in the dynamic visual acuity test (DVAT) between collegiate athletes who are deaf or hard-of-hearing (D/HoH) (n = 38) and university club-level athletes who are hearing (n = 38). Dynamic visual acuity was assessed using the Bertec Vision Advantage (Bertec® Corporation, Columbus, Ohio, USA). No statistically…

Excessive crowding in the visual periphery has been demonstrated in children with developmental dyslexia (DD). However, less is known about crowding in the fovea, even though foveal crowding is at least equally important, as reading is mostly accomplished through foveal vision. Here we used a special set of digit stimuli (Pelli fonts) to measure…
