Relation of socioeconomic status to logical and sociomoral judgment of middle-aged men.

Empirical links between socioeconomic status and logical and sociomoral judgment were studied. Logical judgment was measured with adaptations of the pendulum and correlations tasks devised by Inhelder and Piaget (1958); sociomoral judgment was scored with the standard Kohlberg interview. Measures of socioeconomic status (SES) were status of family of origin and subject's educational attainment and occupational prestige. In a sample of 83 middle-aged men, the 3 measures of SES accounted for 25% and 12% of the variance in logical and sociomoral judgment, respectively. Adult occupational prestige accounted for 6% of the variance in logical judgment beyond that explained by family status and education, suggesting that adult cognitive functioning may be related to occupational placement, occupational experience, or both.
