Abstract:	This study examines whether the recognition of emotion from facial expressions is impaired by deterioration of spatial resolution, contrast resolution, and picture size. Eighty judges rated 65 stimuli under 11 conditions: Undistorted, reduced spatial resolution (three steps), reduced contrast resolution (three steps), reduced picture size (three steps), and a very 'hard' condition combining the severest spatial and contrast resolution. Variation in picture quality was achieved by using a digital video recorder. Recognition rate and intensity ratings were not significantly affected by variations in contrast resolution or picture size. The only significant reduction of recognition rate and intensity ratings resulted from reduction in spatial resolution, but only with the largest deterioration in such resolution. Results are discussed with respect to the fundamental importance of facial expressions in interaction and communication, and with respect to applications, such as tele-conferencing systems.
