Assessing children’s emotional development

Investigating developmental changes via multiple cues


Understanding one’s own and others’ emotions is an essetial skill in interpersonal communication. To investigate the development of emotion understanding in children, we computerized the Affect Knowledge Test (Japanese version) and developed an emotion voice test. These assessment tools allow us to examine how children percieve and process multiple emotion cues and to objectively quantify their development. Compared to the traditional method in which only trained experimenters can administer assessments to children, the computerized tests made it possible to assess children’s emotion understanding in any setting without experts. Using the tests, researchers as well as teachers would be able to detect children with developmental delays and those who struggle with interpersonal communication, and to find which emotional cue is difficult for them to percieve. Obtaining this information would allow us to develop an appropriate intervention to facilitate their development.
