The expression of emotions through face, voice, and body is a central component of the emotion process: together with the perception of social signals and the resulting inferences (impression), expression forms the basis of emotional communication in both animal and human interactions. This summer school proposes a comprehensive survey of fundamental theories of expression and impression - both verbal and non-verbal -, major research paradigms and results, and cutting-edge methodologies from the vantage point of different disciplines, including psychology, neuroscience, ethology, philosophy, musicology, literature, rhetoric and the arts.
