Jordan, Valerie Barnes – 1976
A reanalysis of B. Inhelder's (1968) data concerning cognitive development among retardates was performed by selecting from the original 159 subjects a sample of 104 educable mentally retarded Ss (7-19 years old) who were diagnosed as fixated or nonfixated at three of the cognitive stages postulated by Jean Piaget. The results indicated that among…

A study of 18 Down Syndrome and 18 other mentally retarded adults found evidence of a significant erosion of Wechsler Intelligence Scale for Children scores from the third to fourth decades of life. The Block Design subtest was especially vulnerable to performance decline with age in the Down Syndrome adults. (Author/JDD)

This report discusses the outcomes of a study that examined 216 comparably aged children and adolescents (ages 2-18) with fragile X or autism to determine whether longitudinal change in cognitive ability and adaptive behavior was similar in the two groups. Results found decreases in Intelligence Quotient scores in young children with fragile X as…

Higgins, Thomas J.; And Others – 1979
The perceptions of parents of 113 developmentally delayed preschool children were compared with mental ages derived from the Cattell Infant Intelligence Scale and the Stanford Binet Intelligence Scale. With the parents as informants, an Alpern-Boll Developmental Profile was completed. Findings demonstrated a high degree of correlation between the…

PDF pending restorationHendon, Donald W.; And Others – 1974
To learn if differences in age, intelligence, and sex account for differences in children's memory of TV commercials and "degree of insistence" (DI) after viewing them, 54 gifted, 71 normal, and 53 educable mentally retarded children (of both sexes, 7-13 years) were questioned. The mediating influence of the three independent variables on DI was…

Boswell, James D. – 1969
The interrelations between mental age (MA), IQ, and mediation were studied in 72 retardates in special classes. Subjects were selected to fall into sexually balanced groups of six in 12 MA-IQ categories (IQ 50-59, 60-69, 70-79, and 80-89; MA 4-0 to 5-11, 6-0 to 7-11, and 8-0 to 9-11). The apparatus alternately displayed two pairs of stimuli, and…

Siegenthaler, Bruce M. – 1970
Tests were administered to 209 educable mentally handicapped children (mean age 10.8, mean IQ 77) to determine factors related to speech hearing. Results indicated that mental age, intelligence quotient, physiological age, institutionalization, and organic bases for retardation were not significantly related either to speech reception threshold or…

Stein, Joan Lerner; Budoff, Milton – 1973
Compared were performances of 39 educable mentally retarded (EMR) Ss, mean chronological age (CA) 11 1/2 years, mean mental age (MA) 7 3/4 years; 25 fifth graders matched on CA; and 27 second graders matched on MA to determine whether children of different ages and IQ spontaneously demonstrate learning strategies after repeated practice with…
