Gruen, Gerald E. – 1971
Three studies compared learning and problem-solving performances of normal and familially-retarded children on tasks differing in complexity, and one study investigated motivational-personality differences. Main purpose of the first three studies was to investigate the controversy between developmental and defect theorists in mental retardation.…

Hulme, Charles; Turnbull, Jennifer – British Journal of Psychology, 1983
Explores the generality of findings relating intelligence to Inspection Time (IT), the exposure necessary to judge which of two lines is longer, in two studies using normal children and mentally retarded adults. Results showed the relationship between IT and performance IQ was lower in the mentally retarded group. (JAC)

Morgan, Allison E.; Singer-Harris, Naomi; Bernstein, Jane H.; Waber, Deborah P. – Journal of Learning Disabilities, 2000
Forty children (ages 7-11) referred for evaluation of learning problems, who had normal scores on measures of academic achievement, were compared to 81 similarly referred children who had scored low.

Monk, John S.; And Others – 1985
This study was conducted to determine how the pattern of learning on an abstract concept, plate tectonics, differed between groups of different cognitive levels, sex, and intelligence quotient (IQ). The intensive time-series design was used to examine the achievement of eighth grade and ninth grade earth science students. The unique characteristic…

Cohen, Ronald L.; Nealson, Judi – Intelligence, 1979
Retarded subjects were compared with mental- and chronological-age matched controls on serial short-term memory (STM) tasks. Retarded subjects were inferior to the control groups on both primacy and recency items, under two recall conditions. These data are discussed in relation to possible mechanisms underlying IQ-related individual differences…
