Question: Do different kinds of executive training produce different training outcomes?
Visuo-Spatial Task Switch (Mayr Laboratory, University of Oregon)
(test duration: 20-30 minutes).
1 = On Task: Made a mistake. Did not make a mistake
2 = Off Task: Tuned out. Maybe made an error. Zoned out – have no idea.
A ten camera system with 31 reflective markers (Motion Analysis Corporation, Santa Rosa, CA) capture subject whole body motion at 60 Hz.
DVs: Hip & Torso angles; Coordination of body segments.
Subjects are fitted with an Athletic Connection Polar E600 heart rate monitor (Polar Electro-USA). A chest strap with heart sensor sends information on heart rate and walk time to a wrist recorder.
