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.

UI	MeSH Term	Description	Entries
D008297	Male		Males
D008568	Memory	Complex mental function having four distinct phases: (1) memorizing or learning, (2) retention, (3) recall, and (4) recognition. Clinically, it is usually subdivided into immediate, recent, and remote memory.
D008607	Intellectual Disability	Subnormal intellectual functioning which originates during the developmental period. This has multiple potential etiologies, including genetic defects and perinatal insults. Intelligence quotient (IQ) scores are commonly used to determine whether an individual has an intellectual disability. IQ scores between 70 and 79 are in the borderline range. Scores below 67 are in the disabled range.
