This study aimed to develop a valid and reliable instrument that measures the functional vision of students with low vision. Thus, an assessment tool and performance activities were developed for three vision skill groups (near vision skills, distance vision skills, and visual field) that include functional vision skills. The universe was 1485…

Background: Early identification of deaf-blindness is essential to ensure appropriate management. Previous studies indicate that deaf-blindness is often missed. We aim to discover the extent to which deaf-blindness in people with intellectual disability (ID) is undiagnosed. Method: A survey was made of the 253 residents of an institute offering…

Results of three factor analyses on the Frostig DTVP subtests indicated that the test measures one general visual perception factor, rather than the five postulated by Frostig. (Author/KW)

It is concluded from the study that the three tests tested are not interchangeable despite the fact that they appear to measure similar perceptual functions. All three tests should be combined in a battery if used for diagnostic purposes. (Author)

Instruments for screening visual performance, for observing vision behavior, the learner in general, and the student at a learning task, and a parent questionnaire are described. (See TM 001 363 for a description of the total project; for other related documents, see TM 001 160, 364-368, 370-374.) (MS)

Identifies some functional vision problems and describes some assessment procedures for determining whether a child needs professional help. (MKM)

SUPPORTIVE EVIDENCE IS GIVEN AGAINST PERCEPTUAL DISORDERS CREATING INTERFERENCE IN LEARNING. THE CONTENTION THAT A PERCEPTUAL FIGURE GROUND DISTURBANCE NECESSARILY INTERFERES WITH THE LEARNING PROCESS IS NOT SUPPORTED BY THE EVIDENCE. THERE ARE INDICATIONS, HOWEVER, THAT BACKGROUND INTERFERENCE SEEMS TO AFFECT SOME CHILDREN MORE THAN OTHERS. TWO…

This manual is intended to provide information leading to reliable assessment of vision and hearing capabilities of children considered to have dual sensory impairments. Ongoing sensory assessment is necessary to determine the extent of residual sensory abilities that should be considered in educational programming decisions and to determine any…

Vision screening appears to be particularly important for adult education (AE) programs. Although expected failure rates for school-age population vision screenings are 15 percent, vision screenings of AE clients have yielded dramatically higher failure rates. Vision screenings of 106 Illinois AE students have shown that 66 percent had one or more…

THE INSTITUTE'S TEST BATTERY IS INTENDED TO ASSESS THE CHILD'S ACHIEVEMENT IN COGNITIVE STYLE, PERCEPTUAL ABILITY, LANGUAGE DEVELOPMENT, AND READING ACHIEVEMENT. THE TWO MAJOR PHASES IN THE INSTITUTE'S RESEARCH PROGRAM ARE EXPLORATION OF EARLY ENVIRONMENTAL FACTORS AND THE DEVELOPMENT OF SCHOOL REMEDIAL, READING, AND ENRICHMENT PROGRAMS. THE INDEX…

Although it is frequently assumed that students who meet college entrance requirements have mastered basic reading skills, the presence of so many college reading and study skills centers argues that such is not the case. Many college students need help with some basic skills. To provide such help, careful diagnosis of individual abilities is…

An instrument used to assist teachers in the prescription of appropriate print size for the partially sighted student, the Teacher's Evaluation for Low Vision Needs, was field-tested for reliability with 54 legally blind and partially sighted students (7-14 years old) who used large print books. (Author/DLS)

Strabismus and amblyopia are two common childhood vision conditions requiring early identification and treatment. Screening devices include external examination of the eye, ability to track, a cover test, acuity tests, and stereoscopic tests. Treatment includes patching therapy, use of glasses, orthoptics, CAM vision stimulator, or a combination…
