Previous research indicates relative independence between the ventral and dorsal visual pathways, associated with object and spatial visual processing, respectively. The present research shows that, at the individual-differences level, there is a trade-off, rather than independence, between object and spatial visualization abilities. Across five different age groups with different professional specializations, participants with above-average object visualization abilities (artists) had below-average spatial visualization abilities, and the inverse was true for those with above-average spatial visualization abilities (scientists). No groups showed both above-average object and above-average spatial visualization abilities. Furthermore, while total object and spatial visualization resources increase with age and experience, the trade-off relationship between object and spatial visualization abilities does not. These results suggest that the trade-off originates through a bottleneck that restricts the development of overall visualization resources, rather than through preferential experience in one type of visualization.
