*Significant p-value alpha level of .01. η2 effect sizes of .01, 06, and .14 represent small, medium, and large effects sizes respectively.
- Immobility Duration: Average amount of time, in seconds, spent sitting still (moving less than 1Â mm) during a 5Â min. period.
- Movements: Average number of position changes (movement greater than 1Â mm), measured in total meters during a 5Â min. period.
- Displacement: Total distance traveled (in meters) by the marker during a 5Â min. period.
- Area: Size and shape, measured in cm2, of the space covered by the marker during a 5Â min. period.
- Spatial Complexity: Complexity of the movement path (values range from one to two). Lower values indicate more linear, back & forth movement; higher values indicate more complex movement.
- Temporal Scaling: Frequency of movement (scale from 0 to 1; 0 = no movement and 1 = constant movement).
