Then the Mann-Whitney test was used to analyse the post-test dart scores, which showed that the extremely significant difference between the two groups ( Z = -4.37, p < 0.001, η 2 p = 0.55), the performance of the self-talk group (median: 103.87; IQR: 3.52) was higher than that of the control group (median: 100.87; IQR: 0.75).
