Paternal occupational intelligence and mental deficiency

Abstract

A study was made of 439 feeble-minded children at Vineland Training School. The data on IQ, etiology and paternal occupation were classified. The distribution of paternal occupation for 116 feeble-minded subjects of primary etiology was skewed toward the lowest occupational class. For 123 feeble-minded subjects of secondary etiology, the curve of distribution was symmetrical and resembled a random sample of adult males in Minneapolis. The distribution of paternal occupation for the total group was found to be undifferentiated and irregular. Negative relationship between IQ and paternal occupational status was found for all three groups. (PsycInfo Database Record (c) 2025 APA, all rights reserved)
