In contrast, here we see the reverse. That is, more action with the dominant hand leads to less drift—and more action near the shoulder leads to more drift. While we posit our two findings converge in that they both suggest drift modulation occurs as a function of habitual hand use, this apparent contradiction suggests the precise mechanism relating action and integration may remain to be determined. While our interest here lies in action-based effects on integration, it is now being increasingly recognised that causal inferences about perceptual signals influence sensory perception and processing (Kording et al. 2007; Shams and Beierholm 2010). In this way, visual plausibility might affect the integration of visual and proprioceptive inputs to shape drift. Specifically, if the hand operates more frequently in a particular area of space, this might alter computation regarding the reliability of visual or felt inputs and influence their integration. This is consistent with previous findings showing that visual rotation of a rubber hand (into an anatomically impossible position), causes reduced drift (Costantini and Haggard 2007). Finally, it may also be important to consider potential differences in action-based effects on multisensory integration demonstrated between hands, as opposed to those occurring across space."}
