Cognitive representation of motion in individuals with mental retardation.

Participants with and without mental retardation were compared on their tendency to show the representational momentum effect when viewing a stimulus array that implied motion. The representational momentum effect occurs when, due to implied or apparent motion, an object is more likely to be remembered slightly shifted in the direction of motion rather than against the direction of motion. Participants with mental retardation showed the representational momentum effect as did participants without mental retardation, though the magnitude of the memory shift was smaller for participants with mental retardation. Results suggest that individuals with mental retardation cognitively process motion information in the same general way as do those without mental retardation, although less efficiently.

Implicit and explicit memory in individuals with mental retardation.

Students with and without mental retardation from three age groups were compared on implicit and explicit memory tasks. Consistent with previous research on intelligence-related differences in controlled and automatic processes, students without mental retardation performed better than those with mental retardation on the explicit memory task, but there was no difference between groups on the implicit memory task. For both groups implicit and explicit memory increased from age 6 to 8 to age 10 to 12, but did not significantly increase to age 15 to 17. Because implicit memory appears to be a relative strength for students with mental retardation, we suggest further exploration into broader types of implicit processes that may be useful in training situations.
