In the present study, we investigated whether a spatial motor task affects numerical processing in the auditory modality. Blindfolded participants were presented with a numerical interval bisection task, while performing a tapping task with either their left or right hand, either in the fronto-central, fronto-left, or fronto-right peripersonal space. Results showed that tapping significantly influenced the participants' numerical bisection, with tapping in the left side of space increasing the original tendency to err leftward, and tapping to the right reducing such bias. Importantly, the effect depended on the side of space in which the tapping activity was performed, regardless of which hand was used. Tapping with either the left or right hand in the fronto-central space did not affect the participants' bias. These findings offer novel support for the existence of bidirectional interactions between external and internal representations of space.
