A debated question in cognitive psychology regards to the origin of the numerical-spatial associations that are usually found when individuals process numbers. Recent works have shown that visuospatial or verbal short-term representations of numerical information could be responsible of these spatial effects. Moreover, ordinal information, instead the longstanding assumed magnitude information, seems to have a prominent role when participants perform a parity task. In the present work, we conducted a series of experiments in which different types of non-verbal information (ordinal, visual or spatial) had to be maintained while participants performed a comparison task or a parity judgment task. The results showed that type of information to be maintained produced a differential effect on the numerical-spatial association. However, it is also dependent on the numerical task.
