Previous studies based on single mitochondrial markers have shown that the common raven (Corvus corax) consists of two highly diverged lineages that are hypothesised to have undergone speciation reversal upon secondary contact. Furthermore, common ravens are paraphyletic with respect to the Chihuahuan raven (C. cryptoleucus) based on mitochondrial DNA (mtDNA). Here we explore the causes of mtDN...

introduction zinc is a vital micronutrient in humans and its deficiency in children can thwart their growth and development, compromise their immunity and cognitive function. however, there is a paucity of studies about the effect of zinc supplementation on cognitive functions. this study is an attempt to quantify the impact of zinc supplementation on cognitive performance of schoolchildren. ma...

The purpose of this project was to examine the nature of performance, and specifically, age-related performance, on the Raven's Advanced Progressive Matrices (APM) Test (Raven, Court, & Raven, 1983). In the 1st of 2 studies, 2 tests presumed to measure each of 4 hypothesized components of the APM and 3 tests presumed to measure processing speed were presented to 165 young adults. On the basis o...

The present paper reports secular trends in the mean scores of a language, mathematics, and a Raven-like test together with a combined general ability (GA) score among Norwegian (male) conscripts tested from the mid 1950s to 2002 (birth cohorts c1935–1984). Secular gains in standing height (indicating improved nutrition and health care) were also investigated. Substantial gains in GA were appar...
