Iconic store readout of mildly mentally retarded and nonretarded individuals. 1981

J L Mosley

Mildly retarded and nonretarded subjects matched for MA and CA were required to report tachistoscopically presented linear arrays of letters differing with respect to the number of letters per array. On some trials a visual mask appeared coincidentally with or at variable intervals following the onset of the letter array. By varying information load and stimulus onset synchrony and by including a no-mask condition, it was possible to assess the iconic store readout for each of the three groups. Results revealed that the mask was influential in disrupting the sensory store readout for all groups and that the low-MA subjects demonstrated a slower sensory store readout relative to the equal-CA group. The retarded subjects demonstrated the slowest sensory store readout.

UI MeSH Term Description Entries
D007360 Intelligence The ability to learn and to deal with new situations and to deal effectively with tasks involving abstractions.
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.
