1. Subjective speed of passage of time as an index of body illusion amplitude Fosco Bernasconi

2. Hypothesis: Time perception is modified with different degree of attention. The intensity of body illusion should modulate attention load. Duration estimation may index the amplitude of body illusion. Different degrees of illusion (hand, full body, etc.) should result in different degree of perceived duration compression

3. Control condition (no illusion): : Duration estimation (DE) task Experimental condition: Virtual hand projection Virtual trunk projection Virtual full body projection Duration Estimation

4. Expected results: Hand Trunk Body Produced/perceived duration Illusion Amplitude

5. Limits: Is attention the only factor involved in illusion’s intensity??? Is it possible to make a time estimation during the illusion???
