Abstract
  • Autism and Alexithymia are two disorders characterized by deficiencies in interpersonal and emotional processing. For example, both of these disorders are associated with deficits in the ability to identify and judge the emotions of others. For diagnosis, patients are typically assessed for such deficiencies using published tests of emotion perception (e.g., the DANVA-2, the MSCEIT, the PONS) that require one to assess the emotion being displayed by a target person in a photograph or brief film clip. These tests are well known and used often, but it is rare for researchers or clinicians to ever give more than one of them to an individual. Although all three look like they are assessing the same skill, a systematic study of their agreement to show convergent validity has yet to be undertaken. The purpose of this study is to cross validate three measures of emotion perception ability. High correlations between these tests will increase the confidence researchers and clinicians will have in their validity to assess one’s skill in emotion perception and validate current diagnostic procedures for detecting disorders of interpersonal and emotional processing (e.g., autism or alexithymia). This study had 189 undergraduate psychology students take the PONS, DANVA-2, and MSCEIT. The PONS features video clips of various facial, body and voice expressions, where participants identify the emotional context. The DANVA-2 features face and body pictures, as well as voice clips, where participants identify what emotion is expressed. The MSCEIT features face and environmental pictures for emotional quantification by participants. As expected, all three tests of emotion processing skill correlated significantly with each other, thus providing evidence of their general validity. However, an unexpected result was observed as subscales that were most comparable in content (e.g., “reading faces for emotion”) did not show the strongest level of agreement with each other. Specifically, none of three tests subscale for perceiving emotional expressions in faces correlated significantly despite being the subtest that looked the most familiar across tests. This implies each test may be assessing different aspects of emotion processing that have not been recognized by researchers or even the test creators. Until the convergent validity for the subscales of these three tests can be established, the DANVA-2, MSCEIT, and PONS should not be considered interchangeable. They may be diagnosing aspects of emotional intelligence relevant to disorders such as Autism or Alexithymia, but they are not assessing the same exact thing.
