The graph below is from a study by Wulf + Su (2007), showing accuracy scores where higher scores = greater accuracy. In the external focus group, subjects were instructed to focus on the swing of the club. The internal focus participants were instructed to focus on the swing of their arms. The control group was not given attentional focus instructions. Based on these data, which statement is incorrect?
- The external focus group outperformed the 2 other groups during the practice (acquisition) period
- The control + internal focus group did not significantly differ in performance
- The external focus group demonstrated superior performance in a retention test (without instructions)
- The external focus group retained the same level of performance they exhibited at the end of the practice period
- All of these statements are true
the external focus group retained the same level of performance they exhibited at the end of the practice period
