序列学习场景条件下学习序列与空间记忆内在参照系的建立

Previous studies showed that preferred directions in pointing judgments (e.g. imagine you are standing at X, facing Y, please point to Z) were consistent with the sequence participants used to learn locations of objects suggesting that the learning sequence may determine the intrinsic frames of reference in spatial memory. Numerous studies pay excessive attention to the selection of intrinsic frames of reference in spatial memory acquired from viewing an entire layout simultaneously. This research focused on the relationship between the learning sequence and the spatial reference direction in sequentially learning a layout based on the theory of intrinsic reference system. The results indicated that: 1. The intrinsic frame of reference used to specify objects’ locations in memory could not be determined by learning sequence. The learning sequence reflected the encoding of interobject spatial relations aligned with the intrinsic reference directions . 2. when the objects presented sequentially in a random order and the layout geometry structure was either all along or briefly, the preferred heading was determined by the symmetric axis. when the objects presented sequentially in a random order and the layout geometry structure was either not indicated or briefly presented after study, the preferred heading was determined by learning viewpoint. 3. When the objects were presented sequentially along a certain direction, whether the layout geometry structure displayed or not, the effect of the learning viewpoint on selection of intrinsic axis was observed. 4. When participants learned a layout during locomotion, whether the layout geometry structure displayed or not, the initial study perspective was used as a reference direction in memory. 5. Spatial reference direction was determined at the very beginning of learning objects’ locations. Spatial reference direction could not be changed once it had been choosed. These results not only contribute to specify in greater detail the nature of these spatial representations but also extend the intrinsic model of spatial memory.
