A weight illusion produced by lifting movements.
The perceived relative heaviness of objects was manipulated by instructing 13 subjects to lift them gently or vigorously, as was predicted by the motor theory of weight judgment and the known behavior of proprioceptors. The time-order error was shown to be significantly related to lifting movements.
