Purpose: The purpose of this study was to determine the acute dose-response relationship of classroom exercise breaks with executive function and math performance in 9- to 12-year-old children by comparing 5-min, 10-min, or 20-min classroom exercise breaks to 10 min of sedentary classroom activity. Method: This study used a within-subjects…

Young children removed from institutions and placed into foster care or adoptive homes have been shown to experience significant gains in IQ relative to children who remain in institutions. Less is known about the long-term impact of severe early deprivation on development in late childhood. Data are presented from a follow-up of children at 12…

The purpose of the article is to articulate and compare three major approaches or paradigms of gifted education, so that researchers and practitioners can be more explicit about their assumptions, goals, and educational strategies in their research and practice. We first define the term "paradigm", and then delineate three paradigms in the…

Failure to "activate" relevant, existing background knowledge may be a cause of poor reading comprehension. This failure may cause particular problems with inferences that depend heavily on prior knowledge. Conversely, teaching how to use background knowledge in the context of gap-filling inferences could improve reading comprehension in…

Although it is well established that preterms as a group do poorly relative to their full-term peers on tests of global cognitive functioning, the basis for this relative deficiency is less understood. The present paper examines preterm deficits in core cognitive abilities and determines their role in mediating preterm/full-term differences in IQ.…

The Lothian Birth Cohort 1936 sample is in a uniquely good position to provide relevant data on social class mobility patterns over most of the last century. These participants, with known ultimate social class attainment, took a validated mental test in the Scottish Mental Survey of 1947 and were followed up at approximately age 70. Then, besides…

The practice for identification in the area of specific learning disability has historically included IQ testing and comparing the sub-tests for a discrepancy. Unfortunately, this discounted students whose IQ was too high for the MR (mental retardation) category but did not have high discrepancies among sub-tests. These "flat-liners" could not be…

Presents a study of a theoretical confluence model which predicts the effects of birth order, child spacing and family size on intellectual development. The fit of this model was tested on samples of families with biological and adopted children. (JMB)

The estimation of genetic models reported by J. L. Jinks and L. J. Eaves in a recent review are critically examined. A number of errors in procedure and interpretation are found. It is concluded that the evidence, provided by kinship correlations, for the proposition that intelligence is highly heritable, is not persuasive. (Author/BJG)

While many studies of motor control in autism have focused on specific motor signs, there has been a lack of research examining the complete range of subtle neuromotor signs. This study compared performance on a neurologic examination standardized for children (PANESS, Physical and Neurological Exam for Subtle Signs, Denckla ["1974 Developmental…

Examined main and interactive effects of multiple social risk factors and preschool IQ and mental health on students' academic trajectories from first to twelfth grade. Found that high-risk students had lower grades and more absences from first to twelfth grade than low-risk students. Higher IQ and better mental health improved the grade point…
