Here we put forward a new paradigm - that we usevirtual reality to (temporarily) transform the self.

Behave differently as the self varies?

Virtual Reality Can Make You Fat
• Can VR generate the illusion of having a much fatter belly?

Drift = After measure - Before measure
Monday, June 27, 2011
Results
• Average drift was positive - for the synchronous condition
• people overestimated their size after the experiment
• Questionnaire ratings of body ownership were high for the synchronous condition
• The questionnaire scores were correlated with drift
• Synchronous condition led to feeling of larger body.

Changing the Structure of the Body with VR:A Very Long Arm Illusion
Monday, June 27, 2011
Results
• The virtual arm can be incorporated up to about 3 times the real length
• strong subjective responses
• felt position of the hand changed after the elongation
• subjects responded to the falling knife
Monday, June 27, 2011
Conclusions• Virtual embodiment and transformation appears to
be possible.
• We are just starting to investigate the potential benefits of this:
• Put yourself in the shoes of the other
• Change in attitudes (if desired)
• Rehearsal and preparation for events from different standpoints
• Applications in health and psychotherapy
• Excellent tool for neuroscience to experiment with embodiment
• While keeping eyes on the ethical implications
