Title / Titel Laughter
PDF Abstract (PDF, 14 KB)
Summary / Zusammenfassung Laughter is considered an universal marker for joy (alongside smiling, see e.g., Elfenbein & Ambady, 2002; Ekman, 2003; Gendron, Roberson, van der Vyver, & Feldman–Barrett, 2014; Hawk, van Kleef, Fischer, & van der Schalk, 2009; Laukka et al., 2013; Sauter, Eisner, Ekman, & Scott, 2010; Sauter, McDonald, Gangi, & Messinger, 2013) and one of the nonverbal signals with the most positive valence (e.g., Lima, Castro, & Scott, 2013; Soares et al., 2013). Still, surprisingly little is known about individual differences in the propensity to express laughter, and how the laughter morphology is affected by differing levels of intensity and attempts to regulate laughter. Also, while laughter is commonly associated with amusement (see e.g., Ekman, 2003; Ruch & Ekman, 2001), there are several indications that laughter may go along with other positive emotional states. Thus, studies are needed to clarify the factors (i.e., personality, elicitors, intensity, regulation) influencing the elicitation and morphology of laughter in order to a) appropriately interpret individual differences in the laughter expression in research and applications, b) develop appropriate assessment methods of laughter, c) being able to distinguish different laughter types, and d) understand the nature of positive emotions better. In this project, several studies are conducted to investigate laughter elicitors, morphological features and personality influences. It builds up on initial findings from the ILHAIRE project (see here *Link to: http://www.research-projects.uzh.ch/p15405.htm) and findings from the SNSF project “The joyful face may hide an evil mind: Individual differences in fearing laughter” (see here *Link to http://www.research-projects.uzh.ch/p12354.htm)
