Design outcomes
Primary
| Measure | Time frame |
|---|---|
| The primary study parameter is the estimation error that participants have before and after induction of the OBI. We will calculate the percentage of misestimation for shoulders, waist, hips before the OBI is induced and after the OBI is induced. | — |
Secondary
| Measure | Time frame |
|---|---|
| We will investigate whether the OBI does not only affect size estimation of the body, but whether it also affects other aspects of body image. The main study parameters are the score on the cognitive measure of body image (VAS scale), the average size estimate over all trails in the tactile measure of body image, the percentage of misestimation for the hoop that one's body would still fit through in the movement task assessing bodily action. | — |
