As follow up to a study which compared forced-choice preferential looking (FPL) with pattern visual evoked potential (VEP), this study increased the VEP success rate and improved agreement between the FPL and VEP acuity estimates by using horizontal bar stimuli for young preverbal children (n=17) with nystagmus.

Seventeen preschool children were administered two color-discrimination pretests, verbal and nonverbal. The five children who scored lowest were chosen to recieve the color program. Four scored elow 85 percent on the nonverbal pretest, whereas the other 12 children scored above 85 percent. On the verbal pretest, all five experimental subjects…

The relationship between visual and auditory performance and reading achievement came under scrutiny in this study. It was thought that both poor and average readers would perform better on auditory tasks than on visual ones but that this discrepancy would be considerably greater for the poor or retarded reader. Seventy-two children from grades 1,…

This study found that, of 18 children with severe visual and multiple impairments assessed using the Acuity Card Procedure (originally developed for assessing the visual acuity of infants), 42 percent responded. A similar group received a simple instructional intervention prior to testing and that group's response rate was 85 percent. (Author/DB)

Studies have suggested attention-free semantic processing of natural scenes in which concurrent tasks leave category detection unimpaired (e.g., F. Li, R. VanRullen, C. Koch, & P. Perona, 2002). Could this ability reflect detection of disjunctive feature sets rather than high-level binding? Participants detected an animal target in a rapid serial…

An experimental test of visual closure based on an information-theory concept of perception was devised to test the ability to discriminate visual stimuli with reduced cues. The test is to be administered in a timed individual situation in which the subject is presented with sets of incomplete drawings of simple objects that he is required to name…

This article describes addition of a "learn a routine" procedure to functional visual assessments of children with severe neurological and physical disabilities. The procedure capitalizes on the child's interest of the moment and provides information on the child's patterns of responses, ability to accommodate to variations of a stimulus, and…

EIGHT ITEMS THE "GUILFORD-ZIMMERMAN TEMPERAMENT SURVEY" (E.G. , "YOU MAKE DECISIONS ON THE SPUR OF THE MOMENT") WERE DRAMATIZED AND FILMED IN TWO POLARIZED SITUATIONS, ONE DEPICTING A SPECIFIC SET OF BEHAVIOR TO SUPPORT AN AFFIRMATIVE RESPONSE TO THE TEST ITEM AND THE OTHER DEPICTING A NEGATIVE SPECIFIC. TWO ADDITIONAL…

The question of whether pupil diameter indicates information processing load during reading was investigated in three experiments involving 24 college students reading passages of varying difficulty. A TV camera and monitor, together with a video-recorder, were used to measure the diameter of the pupil under a reading condition and under three…
