Apparatus and experimental conditions. a Ruler used for estimation of hand position (note: hand was not visible, but is presented here to demonstrate how finger position estimations were made). b Arrows demarcating the combination of the six raw RHI conditions into the four hand position conditions. The RHI induction in any one condition would shift felt hand position from the location of the arrow end, to the position of the arrow tip—as in the example c showing shift from the actual hand location (position 2) to the hand image position (1), again the actual hand position was not visible. d Computer screen used to present stimuli. e Mirror used to reflect stimuli on the screen above—making hand image appear as if it was located below the mirror in the same spatial depth plane as the actual (hidden) hands. f The experimental workspace where the participant’s actual hand was placed. g Computer tower. h Cover used to prevent vision of the participant’s body
