To elaborate the cognitive model accounting for our judgments of emotion from facial expressions, the present study tried to investigate experimentally the unquestioned issues on the model as follows :(1) the relationship between the principal components(eigenfaces) and affective judgments involved in the facial expression recognition, (2) the principal components of facial images involved in the judgment of emotional smile, (3) the relationship between the affective judgments and categorical judgments of facial expressions of emotion, (4) the contextual effect of postures on the judgment of emotion from facial expressions, and (5) the contextual effect of shades of the face on the judgment of emotion from facial expressions. Each experiment obtained the data for verifying and elaborating the cognitive model of facial expression recognition.
