The points representing the markedly growth-retarded boys and showing their early response to thyroid hormone administration can be recognized by comparison with Figures 31 to 33. The graphs continueto indicate that in the Marshallese children the skeletal age values at comparable chronological ages are lower (by about6 to 12 months) than the normsfor American children presented by Greulich and Pyle.15 The interpretation of growth data from the exposed Rongelapchildren has been complicated by partial or total thyroidectomies in those children developing nodules (see Thyroid Findings, below) and by the administration of thyroid hormoneto the whole exposed Rongelappopulation since September 1965.

The increase in yearly growth rate in males exposed at <5 years of ageis significantly greater after thyroid treatment (<C0.05) than in unexposed males of comparable age during the sameperiod (based on an analysis of variance using weighted squares of means of yearly growth increments). In orderto probethefeasibility of conducting psychometric tests, the IPAT (Institute of Personality and Ability Testing) Culture Fair Intelligence Test, Scale 2, Form A? was given in 1969 to a group of Marshallese subjects on Rongelap Island and to another group on EbeyeIsland. This particulartest is designed to be comparatively immuneto “contamination by accidents of social, educational, and racial background,”!” and has been used before in several groups of Micronesians.*8
