Effects of spectators on the performance of a dance routine

Abstract

Sports like dancing and gymnastics are often performed in front of an audience. It is therefore an important question whether spectators help or hinder movement execution. Previous research suggests that the influence of spectators on motor performance depends on the type of task, with condition-based tasks being facilitated, and coordination-based tasks being inhibited (for a recent review, see van Meurs, Greve, & Strauss, 2022). We tested a group of female carnival dancers (N = 15, Mage = 19; age range between 15 and 35 years) over the course of a competitive season. The same dance choreography was performed at four timepoints, each time with and without spectators. Dance performances were videotaped and afterwards rated by 7 qualified raters, who were blinded concerning the experimental condition. Raters noted an increased quality of the dance with increasing practice (linear and cubic trend). Concerning social facilitation effects, dance performance was either improved (timepoint 2) or unchanged (timepoints 1, 3, and 4) in front of the audience. Our results indicate that a complex coordination task like the carnival dance may be facilitated when being watched. Future research should address whether these findings can be replicated in other aesthetic sports (like gymnastics), whether they are influenced by gender, and how individual performances influence the group outcome.
