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.
