Persons with mental retardation often exhibit greater interference in visual selective attention tasks than do persons matched with them on CA. My goal here was to evaluate whether differences in distractor interference between persons with and without mental retardation may be related to differences in negative priming. Fifteen participants with…

Visual discrimination and motor reproduction tasks involving computer-simulated arm movements were administered to 12 adults with mental retardation and a gender-matched control group. The purpose was to examine whether inadequacies in visual perception account for the poorer motor performance of this population. Results indicate both perceptual…

Sixty-two adults with mental retardation of heterogeneous etiology performed four facial emotion discrimination tasks and two facial nonemotion tasks. Staff members familiar with the participants completed measures of social adjustment (the Socialization and Communication domains of the Vineland Adaptive Behavior Scales and the Social Performance…

Matching-to-sample skills are involved in language acquisition and reading and counting abilities. The rapid, even errorless, induction of matching performances in young children and 28 individuals with mental retardation (ages 11-20) was demonstrated through the structuring of a visual array that promoted detection of the relevant stimulus.…

This study of visual discrimination training with 22 adults with mental retardation involved either computer-delivered instruction with a stimulus-fading procedure or teacher-delivered verbal and nonverbal prompts. While the teacher prompts were effective with more subjects, participants learned more discrimination problems with the computer…

This study examined the discriminability of lexigrams versus printed words with eight adults with severe mental retardation. A match-to-sample teaching paradigm was used. Subjects discriminated lexigrams better than printed letters and were more successful at matching lexigrams to referent objects than matching printed words to referent objects.…

The ability of 18 aggressive and 21 nonaggressive men with moderate mental retardation to label and discriminate facial expressions was investigated. Although aggressive participants did not have greater difficulty with emotion labeling, they did have a negative emotional bias for facial expressions that were ambiguous to them. (Author/CR)

Scores on the Assessment of Basic Learning Abilities (ABLA), Vineland Adaptive Behavior Scales, and the Wechsler Intelligences Scale-Revised (WAIS-R) were obtained for 30 adults with mental retardation. Correlations between the Vineland domains and ABLA were all significant. No participants performing below ABLA Level 6 were testable on the…
