Testing, both in childhood and as adults, of 28 former pupils of special schools for the educable mentally retarded indicated that pupils who experienced most serious problems in childhood were less retarded as adults than persons who had experienced few or no problems. Results support hypothesis that the effects of early lack of environmental…

Six Hong Kong preschoolers with Down syndrome who attended a center-based educational intervention program were assessed and matched on age, mental age (MA), and IQ. Three of the preschoolers also attended regular preschools two days per week. After a year, the children who also had attended regular preschool had higher MA and IQ. (Author/CR)

Two methodological issues involved in determining the relationship between learning and general intelligence were examined: (1) the use of learning strategies in a paired-associate task and (2) the importance of time (rather than errors) in the measurement of learning efficiency. (Author/RD)

Estimates the influences of home background and formal schooling on adult intelligence quotients using the LISREL computer program and longitudinal data collected in Sweden for 671 men.
