Across three experiments, college students read narratives describing two-dimensional horizontal, sagittal, or coronal environments, each with seven objects in surrounding directions (at 45° angles). Then they responded from memory to questions about which objects were in specific directions. The distributions of error rates and response times were compared with distributions predicted by a mental transformation model and two verbal-spatial decoding and retrieval models. The data fit the predictions of a modified mental transformation model (mental transformation plus 180° exception) better than the predictions of either verbal-spatial model. This was true even though the environment was presented narratively rather than perceptually, and it was true for both the vertical planes in addition to the more typical horizontal plane.
