Previous studies on spatial memory reveal that people represent spatial information in 3 different forms: landmark, route, and survey. The aim of this work was to assess spatial abilities in order to predict a person's cognitive style. In order to do this we used 9 different spatial tasks, which were linked with these 3 forms of spatial representations. We found that the 9 spatial tasks are able to distinguish different levels of spatial ability.

Previous studies on spatial memory have shown that, in judging direction, participants are more accurate and faster when a map is aligned with the perspective of the spatial layout they had learned (alignment effect). Rossano and Warren (1989 Perception 18 215-229) have shown that when participants have to do a contra-aligned judgment they can either answer correctly, or make alignment or mirror-image errors. We think that the kind of response depends on the different way in which people acquire environmental knowledge: landmark, route, and survey. We hypothesise that landmark and route participants show alignment effects and make, respectively, alignment errors and mirror-image errors, whereas survey participants do not show an alignment effect. An experiment is reported in which participants performed three tasks in order to distinguish their cognitive style. We selected thirty landmark, thirty route, and twenty-eight survey participants. They were then submitted to directional judgment tasks to verify whether the alignment effect was present and to observe the kind of responses. The results revealed that survey participants did not show an alignment effect, and that the kind of errors could depend on the directional judgment task participants had to do, and not only on the cognitive style.
