Thirty-six mildly mentally retarded young adults were exposed to one of three training arrangements for vigilance performance, a monitoring task that some professionals consider uniquely appropriate for such persons because they are assumed to be less susceptible to boredom. (Author)

Teacher ratings of the anomalous classroom behaviors of hyperactivity, inattention, perceptual-motor impairment, perserveration, and stereotype were examined as predictors of performance of 82 mentally retarded 6-18 year olds on a visual discrimination task. Weak but statistically reliable correlations were obtained. (Author/CL)

Eighteen moderately mentally retarded adults, 20 nonretarded elementary age children, and 20 nonretarded adults were exposed to three conditions of an auditory detection task (location, meaning, and a combination of both). Developmentally immature subjects (retarded adults and nonretarded children) demonstrated less efficient attentional capacity.…

Sixteen mildly mentally retarded adults were compared on both an auditory and a visual vigilance task with 16 Ss having greater than average intelligence. (Author)

Forty-three severly or profoundly retarded children and adolescents who were presented with a series of three-and 10-trial form discrimination problems learned faster on the first three trials if each problem lasted for ten trials. (Author/MC)

A continuous reinforcement, delayed classical eyelid-conditioning paradigm in combination with the peripheral vasomotor response of digital vasoconstriction was employed to examine the hypothesized attention deficit for 10 15-year-old educable mentally retarded and same-age nonretarded Ss.
