title: Field dependence in relation to alcohol consumption: a co-twin control study.
abstract: 20 male, alcohol-discordant twin pairs, aged 45 to 65 yr. were compared for field-dependent cognitive style and general intelligence by means of one-sample t and multivariate Td2-tests. The high alcohol group was more field-dependent (p less than .01) than the low alcohol group, mainly because of poorer scores on the Embedded-figures Test. When general intelligence was controlled for, the amount of embedded-figures variance accounted for by consumption of alcohol dropped considerably.
