Investigated the relationship between anthropometric indices and behavioral development during the first two years of life in rural Guatemala. Body length and weight most strongly correlated with behavioral development. When length and weight were controlled statistically, variance in behavioral development was accounted for. (Author/DB)

Older children and adults, but not younger children, allowed for dramatic changes in the size and shape of animals over the animals' lifespans. (BC)

Three self-report methods for rating secondary sexual characteristic growth were compared to physician ratings; the accuracy of self-reported height and weight was also assessed. The usefulness of the Pubertal Development Scale, Tanner ratings, and self-reported height and weight as adequate estimates of pubertal development is discussed. (PCB)
