We describe the effects of a Biosymtic robotic device -"Cratus" - on physical activity levels in a group of 20 children aged 6 to 8. Children interacted with "Cratus" via whole-body motion in a natural environment - playing a video game. Expectations and opinions regarding the device were also evaluated. Results indicate that interacting with "Cratus", in a(More)
Rats trained to eat a single meal from 0800 to 1000 AM, (MF rats), increased food intake from the 1st (7.0 g) to the 13th (16.1 g) day and showed higher hepatic glycogen concentration and glycemia during fasting. To verify if these changes were determined by the higher food intake or due to the disciplining condition we compared rats at the 1st (MF(1st(More)
