AI Article Synopsis

  • The study evaluates a reading speed test's effectiveness for measuring central vision by calculating words per minute (wpm) from 30 words of 1.20 logMAR text.
  • Reading speeds varied significantly among different eye conditions, with macular disease patients reading much slower (27.0 wpm) compared to cataract patients (91.9 wpm).
  • The test showed consistency with repeat testing results falling within a +/- 16% range, indicating it could be a valuable tool for assessing central vision in cataract patients.

Article Abstract

This study examines the validity and reliability of a reading speed test as a measure of potential central vision. Reading speed was calculated in words per minute (wpm) from the time taken to read 30 words of 1.20 logMAR size text. Scores were obtained from subjects with cataract (n = 48), macular disease(n = 35), peripheral vision loss(n = 14) and normal eyes (n = 10). Subjects with macular disease (27.0 +/- 13.2 wpm) read much slower than subjects with cataract (91.9 +/- 13.6 wpm). Little difference was found between subjects with cataract, peripheral vision loss (91.5 +/- 14.7 wpm)and normal eyes (103.8 +/- 15.5 wpm). Repeat testing gave values within +/- 16% of reading speed. These results suggest that a reading speed test using large text could be useful as a potential central vision test in cataract patients.

Susceptibility-weighted imaging (SWI) has been widely used in clinical contexts, in which the speed of acquisition is frequently a critical issue. In this study, we aim to test the feasibility of a deep learning (DL)-based reconstruction method for accelerating SWI acquisition in clinical settings. A total of 61 subjects were consecutively enrolled.

Active object recognition, fundamental to tasks like reading and driving, relies on the ability to make time-sensitive decisions. People exhibit a flexible tradeoff between speed and accuracy, a crucial human skill. However, current computational models struggle to incorporate time.

The present study examined the effects of orthographic knowledge (OK), phonological awareness (PA), rapid automatized naming (RAN), and phonological working memory (PWM) on the reading speed, accuracy, and comprehension of elementary school students. Results from a sample of 176 typically developing children in the second through fourth grades (mean age = 8.9 years) revealed that the correlation between reading and the other variables (PWM, PA, RAN, and OK) was significant.

Early numerical skills and mathematical domains in autistic students in primary school.

Introduction: It is crucial to provide a quality educational response to the needs of autistic children across various mathematical domains. However, there is no consensus on which of the early skills have the greatest predictive effect in the short and long term within these domains. Therefore, this research aimed to a) compare early numerical skills and mathematics domains, and 2) analyze the predictive value of early numerical skills into mathematics domains.

Differentiating the neurobiological correlates for reading gains in children with reading difficulties with and without attention-deficit/hyperactivity disorder using fMRI.

Objective: Reading difficulties (RD) frequently co-occur with attention-deficit/hyperactivity disorder (ADHD), and children with both RD + ADHD often demonstrate greater challenges in reading and executive functions (EF) than those with RD-only.

Methods: This study examined the effect of a 4-week EF-based reading intervention on behavioral and neurobiological correlates of EF among 8-12 y.o.
