Researchers Say We Stamp Out A Boy's Natural Emotional Expressiveness - Hartford Courant
A couple excerpts from the above article written ages ago on this topic:
"Because of what seem to be biologically based differences, boys start out life more emotionally expressive than girls," writes psychologist Ronald F. Levant of Harvard Medical School. Research finds that infant boys are 'more emotionally reactive and expressive' than infant girls, and remain so at least until they are 6 months old -- they show more joy, more anger, fussiness and crying, make more gestural signals and 'positive vocalizations' to their mothers, Levant writes in an article in the journal Professional Psychology: Research and Practice.
