We examined what forces are applied to objects that elicit this illusion when they are lifted.We predicted that:
(1) Forces on early trials will scale to each participant’s expectations of how much a particular block will weigh ‐ excessive force will be applied to the metal block and insufficient force applied to the polystyrene block.
(2) Forces on later trials will scale to the real weight of each block ‐ identical levels of force applied to all the blocks.
(3) MWI will persist throughout ‐ polystyrene block will feel the heaviest, metal block will feel the lightest.
