Description

Comparing actual movements to mental imaging movements

Format

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

Details

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.
