A brief childhood window shows how boys learn to hide their feelings

A Space Daily article summarizes Judy Y. Chu’s ethnographic study of six boys from ages four to six, noting that children in this window are highly perceptive and openly expressive, but over the next two years they become more guarded as they learn to align with masculine norms that de-emphasize warmth. The piece connects these findings to similar patterns observed in girls and later adolescence, while stressing that the research is not a causal a priori and does not predict individual outcomes.
