Emotion knowledge in children and adolescents with Down syndrome: a new methodological approach.

Emotion knowledge was examined in 19 youth with Down syndrome (DS) and compared to typically developing (TD) children of similar developmental levels. This project expanded upon prior research on emotion knowledge in DS by utilizing a measure that minimized the need for linguistic skills, presented emotion expressions dynamically, and included social context cues. In Study 1, participants with DS were as accurate as TD participants when judging emotions from static or dynamic expression stimuli and from facial or contextual cues. In Study 2, participants with DS and TD participants showed similar cross-sectional developmental trajectories of emotion knowledge across mental age. This project highlights the importance of measure selection when examining emotion knowledge in samples with intellectual and developmental disabilities.
