Abstract Little research has examined the association between general figure closure speed, a stratum I ability within Cattell-Horn-Carroll (CHC) model of intelligence, and face-specific ability; an important consideration, as some suggests face processing is independent other abilities. Additionally, (general face) may correlate negatively with trait-autism, due to theorised autism-related dif...
determining general and specific combining ability of lines is necessary to use them as parents of hybrid varieties. in addition, estimates of the heritability of characters helps in selecting suitable breeding methods and predicting genetic gains of the traits. to determine general and specific combining abilities and gene effects of agronomic characters, five cms lines and four restorer lines...
Hominid brain size increased dramatically in the face of apparently severe associated evolutionary costs. This suggests that increasing brain size must have provided some sort of counterbalancing adaptive benefit. Several recent studies using magnetic resonance imaging (MRI) have indicated that a substantial correlation (mean r = approximately 0.4) exists between brain size and general cognitiv...
Adaptive fact learning systems have been developed to make optimal use of testing and spacing effects by taking into account individual differences in learning efficiency. Measures derived from these systems, capturing the individual differences, predict later performance in similar and different fact learning tasks. Additionally, there is a rich body of literature showing that individual diffe...
Differences in genomic structure between individuals are ubiquitous features of human genetic variation. Specific copy number variants (CNVs) have been associated with susceptibility to numerous complex psychiatric disorders, including attention-deficit-hyperactivity disorder, autism-spectrum disorders and schizophrenia. These disorders often display co-morbidity with low intelligence. Rare chr...
We review the literature on the relation between whole brain size and general mental ability (GMA) both within and between species. Among humans, in 28 samples using brain imaging techniques, the mean brain size/GMA correlation is 0.40 (N = 1,389; p < 10(-10)); in 59 samples using external head size measures it is 0.20 (N = 63,405; p < 10(-10)). In 6 samples using the method of correlated vecto...
