A paper by M. Hill et al., titled "Benefit-Cost Analysis of Supported Competitive Employment for Persons with Mental Retardation," is criticized due to logic concerns, certain omissions, and some imprecision. The study's conclusions are generally supported, but the certainty of taxpayers benefitting from the employment programs is…

Researchers and service providers working in the field of the mental health aspects of mental retardation need to integrate their efforts, but barriers exist, including differences in culture, negative history, and competition for limited resources. Joint conferences and publications are recommended as well as graduate training programs and…

This review shows that mentally retarded children can produce problem-solving strategies if they comprehend the task requirements, share the experimenter's goal, and construct an optimal problem-solving representation. Instruction with multiple exemplars of a task can induce generalized strategy use, and nonvolitional mechanisms play a role in use…

This paper responds to a 1992 study in which it was argued that the structure of intelligence in adults with severe mental retardation deviates from Greenspan's model, in which social and practical intelligence form separate factors. Application of confirmatory factor analysis to the original correlation matrix found the Greenspan model to be…

This paper discusses inconsistencies in Greenspan and McGrew's argument that confirmatory, rather than exploratory, factor analysis should be utilized in testing Greenspan's model of adaptive intelligence in adults with severe mental retardation. It is argued that problems with the data set should be addressed through further research rather than…
