Aim: To assess the relation between cerebellar volume and spectroscopy at term equivalent age, and neurodevelopment at 24 months corrected age in preterm infants. Methods: Magnetic resonance imaging of the brain was performed around term equivalent age in 112 preterm infants (mean gestational age 28wks 3d [SD 1wk 5d]; birthweight 1129g [SD 324g]).…

This study examined the motivational orientations of 166 graduate students enrolled in distance education courses at a state university. Data were collected utilizing Boshier's Education Participation Scale A-Form and analyses were completed for overall results, by gender and age, by academic program and by preferred method of distance course…

What kind of featural information do infants rely on when they are trying to recognize a previously seen object? The question of whether infants use certain features (e.g., shape or color) more than others (e.g., luminance) can only be studied legitimately if visual salience is controlled, as the magnitude of feature values--how noticeable and…

Does not support the hypothesis that cognitive regression takes place as a part of normal aging. (RL)

Simultaneous maximum likelihood procedures were used to investigate the generality of ability factor structure in adulthood and old age. Data were analyzed for 198 subjects aged 15-32; 173 subjects aged 51-67; and 153 subjects aged 68-83. Variables were 14 ability tests marking five cognitive factors: verbal comprehension, number facility,…

This paper reviews studies in which scores on Piagetian tests of logical thought were correlated with IQ, mental age (MA) and chronological age (CA), and examines the possible effects of the size of the age range and mean age of subjects on these correlations. The data included 44 groups of subjects obtained from 36 studies in which Piagetian and…

This paper describes the scope and findings of a separately published comprehensive review of research on optimum age of entry into first grade, covering the literature from 1915 to 1976. (Not included was research on reading, the gifted, mentally retarded, and materials in popular journals.) Findings noted the inadequacy of chronological age as a…
