The aim of the present study was to test if lateral preferences of surfers are associated with behaviour and performance depending on the direction of a breaking wave. We hypothesized that wave direction and surf stance interact in creating favourable or debilitative performance demands as surfers are either facing the wave (frontside) or the wave is breaking in the back of the surfers (backside). Study 1 was an online survey collecting self-report data of recreational surfers (n = 394). In Study 2, we analysed all wave scores (n = 2,552) and laterality of professional surfers during the season of 2014. Study 1 demonstrated that recreational surfers preferred surfing frontside and described themselves as more skilful when surfing frontside as this is facilitative for picking up visual information. Study 2 did not provide clear evidence that professional surfers on average scored higher during contests when surfing frontside, but when professional surfers had a choice of surfing frontside vs. backside, they were more likely to surf frontside. We discuss the diverging findings between Study 1 and Study 2 from the "circumvention-of-limits" argumentation within the expertise literature as professional surfers most likely have acquired skills allowing them to compensate for debilitative individual and environmental circumstances.

The goal of the present research was to investigate whether claims (postperformance nonverbal emotional expressions) influence people in evaluating performance during surf contests. To test this research question, the authors sampled videos from professional surf contests and asked laypeople (Experiment 1; N = 110) and surf judges (Experiment 2; N = 41) to evaluate the performance in 2 online experiments. A subset of the surfing performances showed surfers displaying postperformance emotional expressions (claims), while another subset showed the same performances without the claims (nonverbal emotional expressions). Both experiments provided evidence that both laypeople and surf judges were biased by claims in judging surfing performances, with claims better than the performances without claims. The findings are in line with social-cognitive models emphasizing the socioconsequences of emotion expressions. The authors discuss the implications of the findings for sport competitions that rely on judging sport performance.
