An interrelationship in the recognition of facial expressions of the six basic and specific emotions has been inferred from neurological cases who have displayed a disproportionate impairment in recognizing them. The previous reports, however, are vulnerable to the criticism that the apparent emotion-specific impairments are merely artifacts due to the various levels of difficulty in recognising the different emotions. We propose a new method for the assessment of recognition of facial expression. In this method, the difficulty artifacts are fully controlled by means of morphing and item response theory (IRT). We used a morphing technique to create intermediate facial expressions which would have various levels of difficulty for recognising each emotion. By using IRT, the sensitivity to the expressions was estimated by taking account of differential difficulty levels. The results revealed that a sensitivity to happiness alone was not correlated with a sensitivity to the other emotions, and indicated that the recognition of happiness was independent.
