The objective of the present study was to examine the effects of gender stereotype on the performance and learning of a classical ballet pirouette in 11-year-old boys. Participants in the stereotype threat (ST) group were informed that, in general, boys tend to show worse results when completing the pirouette task in comparison to girls. Participants in the stereotype lift (SL) group were told that girls tend to show worse results in comparison to boys. The control group did not receive stereotype instructions. The results demonstrated worse performance during practice and retention (next day) for the ST group relative to the SL and control groups; the SL and control groups did not differ. The findings indicate that gender stereotype threat can undermine motor performance and learning in boys.
