Woodley, Michael A. – Intelligence, 2009
In this ecological study, a robust negative correlation of r = - 0.62 (P less than 0.01) is reported between national IQs and consanguinity as measured by the log10 transformed percentage of consanguineous marriages for 72 countries. This correlation is reduced in magnitude, when IQ is controlled for GDP per capita (r = - 0.41, P less than 0.01);…

De Pascalis, V.; Varriale, V.; Matteoli, A. – Intelligence, 2008
The relationship between fluid intelligence (indexed by scores on Raven Progressive Matrices) and auditory discrimination ability was examined by recording event-related potentials from 48 women during the performance of an auditory oddball task with backward masking. High ability (HA) subjects exhibited shorter response times, greater response…

Rammsayer, Thomas H.; Brandler, Susanne – Intelligence, 2007
The relation between general intelligence (psychometric "g") and temporal resolution capacity of the central nervous system was examined by assessing performance on eight different temporal tasks in a sample of 100 participants. Correlational and principal component analyses suggested a unitary timing mechanism, referred to as temporal "g".…

The relationship between nutritional status and intellectual capacity in 6-year-old children was investigated in 83 subjects of medium-high socio-economic status, without any apparent risk of malnutrition and normal or high intellectual capacity. Nutritional status was evaluated by measuring food consumption, anthropometrical measurements and…
