Comparing actual movements to mental imaging movements
A dataset with 32 observations on the following 3 variables.
Action
Treatment: Actual
motions or
Mental
imaging motions
PreFatigue
Time (in seconds) to complete motions before fatigue
PostFatigue
Time (in seconds) to complete motions after fatigue
In this study, participants were asked to either perform actual arm pointing motions or to mentally imagine equivalent arm pointing motions. Participants then developed muscle fatigue by holding a heavy weight out horizontally as long as they could. After becoming fatigued, they were asked to repeat the previous mental or actual motions. Eight participants were assigned to each group, and the time in seconds to complete the motions was measured before and after fatigue.
