A large proportion of the UK adult population has very poor literacy and/or numeracy skills (see the 1999 Moser Report, the 2003 "Skills for Life" Survey and the 2006 Leitch report). In 1999, the Moser report found that approximately 20% of adults in England had severe literacy difficulties, whilst around 40% had some numeracy problems.…

In this study, six children were selected by age and were administered Piagetian tasks designed to measure their level of cognitive development against the hierarchical structuring of age/achievement posited by Jean Piaget. The task administrations are presented in detail with descriptions of the subject and the tasks, a verbatim report, and the…

Delineates the current consensus regarding the nature and the development of intellectual ability. Examines when one would expect general abilities to moderate the relationship among domain-specific and other processes. Reviews recent studies in which general abilities were used as independent variables or covariates. Suggests that generally,…

The application of Piaget's theory of cognitive development to the assessment of mental ability of the mentally retarded is presented. Following a discussion of developmental theories and diagnosis of mental development, testing interviews demonstrate the limits of cognitive thought at each of three stages. Abnormal intellectual oscillations are…

Analysis of 65 children over a 4-year period on tests of operational and causal thinking offers support for Piaget's notion of stage progression. In kindergarten and grade one, the majority of children in this longitudinal study were between preoperational and the achievement stage of operational thought. By grade two, the majority had attained…

When administered to 34 infants with handicaps, Bayley Scale mental age scores were an average of 2.1 months higher than Estimated Developmental Ages (EDA's) calculated from the Uzgiris and Hunt Scales. The EDA's were significantly and positively related to Bayley mental age, and sensorimotor play emerged as the best single correlate. (Author/JDD)

THERE IS GROWING EVIDENCE THAT THE PROCESS OF EDUCATIONAL RETARDATION WHICH HAS BEEN OBSERVED IN MANY CHILDREN FROM ECONOMICALLY DEPRESSED AREAS SETS IN LONG BEFORE THE CHILDREN ENTER THE FIRST GRADE. THIS STUDY WAS DESIGNED TO EXAMINE THE RELATIONSHIP BETWEEN MATERNAL LANGUAGE STYLES AND PRE-SCHOOL CHILDREN'S COGNITIVE STYLES AND INTELLECTUAL…
