<p> The ability to recognize facial expressions facilitates social interactions. In my
Ph.D. thesis, I took three approaches to compare the sensitivity of adults and
children aged 5 to 14 years to the six basic facial expressions: 1) the influence of
intensity on the recognition of facial expressions; 2) the perceived similarities
among facial expressions; and 3) the selective use of spatial frequency
information in recognizing facial expressions. Collectively, these studies reveal
different developmental trajectories for different expressions, with sensitivity to
happy expressions already adult-like at age 5, but changes for some negative
expressions continuing even past age 10. The slow development of adult-like
proficiency with negative expressions may lead children to make errors in judging
the intentions of others. </p> / Thesis / Doctor of Philosophy (PhD)
