Type I incidental learning (in which Ss are exposed to stimulus materials without instructions to learn, and then Ss' retention is unexpectedly tested) of 112 educable mentally retarded children (6-13 years old) was investigated. (Author/CL)

Comparison for memory for spatial location of 30 persons with and 30 persons without mental retardation found the control group recalled more intentionally learned than incidentally learned locations. The experimental group performed better after incidental learning than after intentional learning and scored as highly as controls on incidental…

Three experiments with 164 individuals between 4 and 80 years old examined age-related changes in explicit memory for three perceptual features: item identity, color, and location. Findings indicated that performance on explicit memory tests was not a consistent inverted U-shaped function of age across various features, but depended on the…

Performance on tasks of memory and of attention was consistently interrelated for nonlearning disabled children and less consistently so for learning disabled subjects. Hyperactivity was also related to poorer performance on the cognitive measures. (Author/DB)
