Abstract
Previous studies have shown that lifting a weight with two hands feels lighter than lifting the same weight with one hand. One explanation for this effect could be that increasing the number of digits decreases the total grip force required to lift and hold the object therefore, resulting in a ‘lighter’ percept. Here, we carried out a pilot study on the effect of bimanual lifting on weight perception and total grip force. Preliminary results indicate that bimanually lifted weights feel lighter than unimanually lifted weights and that the total bimanual grip force is not significantly different than the unimanual grip force. Alternative explanations for the illusion of the bimanual ‘lighter’ weight percept are discussed.
