The scientists at the Karolinska Institutet in Stockholm said they showed 198 people images of dolls -- alternately a Barbie-sized doll and a 13-foot-tall doll -- having their legs stroked while their own legs were stroked, The Local reported Friday.

They found those shown images of the Barbie-sized doll overestimated the distance to the blocks as well as the size of the objects, while those shown images of the larger doll underestimated the measurements. "It is a really strong illusion, even when you know that you are being fooled you still believe it," said Bjorn van der Hoort, neurologist at Karolinska Institutet.
