Reliability Generalization of Tasks and Recommendations for Assessing the Ability to Perceive Facial Expressions of Emotion.

Despite a strong research interest in emotion perception ability, this construct is usually assessed without sufficient consideration of measurement reliability, thus limiting its predictive utility. We present an overview of available emotion perception ability tests, followed by a brief review of test reliability concepts, including classical and modern approaches. Then, through a reliability generalization (k = 106, ntotal = 16,859), we evaluate which tests have high internal consistency and which design characteristics are associated with better internal consistency. We conclude with general recommendations for the psychometric evaluation of emotion perception measures and provide recommendations for best measurement practices. Public Significance Statement: Despite intense interest in measuring our abilities to accurately label what another person is expressing, there is comparatively little research understanding the methods by which we make these assessments. We conducted a quantitative summary of the properties of popular tests and found relatively few researchers take the necessary steps to ensure proper measurement. [ABSTRACT FROM AUTHOR]
