Visual and sensory-motor functioning in the classroom: a preliminary report of ergonomic demands.

Observations were made in 11 4th and 5th grade classrooms of the specific ergonomic conditions including physical space, lighting conditions, and academic task demands placed on the students. The data indicate remarkable homogeneity, including the findings that light levels were consistently lowest in the front of the classroom, and that more than 50 percent of the students' time involved near task demands. Observations of behavioral compliance with the task demands will be discussed. We conclude that classroom ergonomic conditions require extensive near work and students with ocular motor dysfunctions may have difficulty meeting the behavioral expectations of the classroom. Implications for future research will be discussed.

Effects of ocular functioning and time upon reading proficiency.

We hypothesize that children with fusional and/or accommodative abnormalities will tend to tire more readily when reading than will children with normal vision and that, consequently, they will show a greater decrement in reading proficiency over time on a task requiring reading. Forty-five subjects who passed the New York State Optometric Association Vision Screening Battery and 32 who failed were given a "maze" reading test developed for the study. The abnormal vision group made significantly more errors than did the normal vision group on the reading test. The abnormal vision group also made progressively more errors than did the normal vision group at the end of each segment of the reading test. The differences, however, were not statistically significant. While the correlations between speed and accuracy reversed over time, the abnormal vision group began and ended at the most extreme levels, having undergone a significantly more radical shift in this regard.

Validation study of the New York State Optometric Association (NYSOA) Vision Screening Battery.

The New York State Optometric Association (NYSOA) Vision Screening Battery was administered to 1983 grade school children. Complete visual examinations were performed on 125 children. A consensus method for determining a diagnosis was developed and a double-blind paradigm was used to validate the screening battery. The sensitivity was found to be 71.7% and the specificity to be 65%. When compared to the Snellen test, the NYSOA battery is far more sensitive. The Snellen test is 100% specific but misses 75.5% of the children found to have vision problems when given a complete visual examination.

The NYSOA vision screening battery--a total approach.

A vision screening battery has been developed by a project team of the New York Optometric Association. This battery screens those visual skills that are important to the academic task demands. This battery is so organized that it can be utilized without the need of a vision care professional. A pre-pilot study was conducted by the New York State Optometric Association and the New York State Educational Department. This battery was a far more sensitive detector of visual problems related to learning than the Snellen alone. This battery was efficiently and effectively utilized by educators and parents without the need of a vision care professional. The battery and statistical study are discussed.
