A group of researchers studied whether claims influence fans and judges in evaluating performance during surf contests.
The paper entitled “Claims in Surfing: The Influence of Emotional Postperformance Expressions on Performance Evaluations” was in the Journal of Sport and Exercise Psychology in December 2019.
The analysis led by Philip Furley, a lecturer at German Sport University Cologne, focused on the post-performance nonverbal emotional expressions and their consequences, in terms of external perception.
