There are frequently two different conceptions used to describe what people store in their memory for environmental layouts. The SOLAR (Straight-Line Object-Based, Local Angular Relations) model and the quasi-Euclidean Framework model. The Framework model assumes that people store coordinated points in their layout of spatial memory. This grid-like representation of points is then used to remember layouts. A common, natural judgment that is used within the Framework model are called judgments of relative direction (JRDs). The SOLAR model, on the other hand, assumes people remember and store information about 3D objects, so characteristics such as fronts can be used as a surface referent to create a third source of information. The SOLAR model assumes that objects are related via straight-line angular relations, so object-based judgments (OBJs) are used within the SOLAR model. Navigation paths also play a key role in the formation of spatial memory. So, the current research examines the relationship between JRDs and OBJs by creating natural, navigable environments. The angles between the facing objects were crafted in a way that certain queries had the same angular relationship across rooms, which allowed for the direct comparison between the two measurements. If OBJs and JRDs use the same underlying processes, the two measurements should be related and should be able to be used to predict each other. This is exactly what our results suggest. This is an important finding because using alternative measures will shed light on spatial memory processes.
