To create highly accurate and reliable maps, cartographers must be aware of cognitive effects that occur when people process map information. Interdisciplinary research from cognitive psychologists showed that map graphics lead to spatial distortions in human spatial memory. These distortions can influence human orientation capacities. Recently, it was discovered that grid structures overlaid on maps help to correct spatial distortions in cognitive representations of geographic space. Square grids chunk a map into smaller units (regions). They guide map-viewing behavior, and their regular structure helps map users to recall learned locations of objects more accurately. The effects caused by square grids may also occur when overlaying other common kinds of geometries, such as hexagonal structures. The effects of hexagonal grid structures on memory of object locations were investigated in this map-experimental study. The study design is based on a recall-memory-paradigm, an established method of experimental psychology to measure performance in memory. The results show that hexagonal grid patterns can improve the performance.

Exploiting illusory grid lines for object-location memory performance in urban topographic maps / Frank Dickmann in Cartographic journal (the), Vol 54 n° 3 (August 2017)

This understanding of geographic space often arises from experience with cartographic media representing topographic and topological information by graphic symbols. Learning spatial information from graphic media is influenced by different perception-based grouping effects distorting the accuracy of spatial object-positions and their relations. Such geometric inaccuracies can be softened by adding a grid layer, which regionalizes the map and can be used as an additional orientation pattern. This grid layer usually consists of solid lines and overlays semantic information. The present paper reports the results of two empirical studies on object-location memory (OLM) performance. In these studies, the amount of visual detail of the grid layer was reduced. By positioning the grid layer below specific urban topographic objects (study 1), the grid pattern was graphically interrupted. These interrupted grid lines were completed by cognitive completion mechanisms (illusory grid lines) described in the Gestalt principles of closure and continuation. The second experiment examined the maximum grid line gap that is closed by cognitive line completion and keeps an advantage for OLM (study 2).

Where is it (in the map) ? recall and recognition of spatial information / Anne-Kathrin Bestgen in Cartographica, vol 52 n° 1 (Spring 2017)  

Public [article]  inCartographica > vol 52 n° 1 (Spring 2017) . - pp 80 - 97 Titre : Where is it (in the map) ? recall and recognition of spatial information Type de document : Article/Communication Auteurs : Anne-Kathrin Bestgen, Auteur ; Dennis Edler, Auteur ; Christina Müller, Auteur ; et al., Auteur Année de publication : 2017 Article en page(s) : pp 80 - 97 Note générale : Bibliographie Langues : Anglais (eng) Descripteur : [Termes IGN] cognition [Termes IGN] géovisualisation [Termes IGN] lecture de carte [Termes IGN] mémoire [Termes IGN] niveau de détail [Termes IGN] rendu (géovisualisation) [Termes IGN] style cartographique [Termes IGN] test de performance [Vedettes matières IGN] Cartologie Résumé : (Auteur) Findings of empirical studies of spatial memory using maps are direct responses to the successful transfer and processing of map information. The memory performance of map users is an important indication of the quality of a map design. Studies of spatial memory have mainly relied on recall performances, but maps can be used in various ways depending on the map user's task and applied strategy. Therefore, one memory paradigm does not cover the entire spectrum of options for examining the retrieval of map information. Three different experiments were designed to analyze and compare memory performances using different map information in recall and recognition (combining episodic and semantic memory) paradigms. The results demonstrate that map complexity, as varied by the amount of displayed map detail, contributes significantly to memory performance. Moreover, memory enhancement affected by map-structuring elements (grids) depends on the respective paradigm and also on the visual appearance of the structuring elements. Both paradigms for examining the influence of map information on cognitive processing can be applied specifically to analyze the efficiency of map designs. On the basis of the different effects of map information, a reasoned application of these paradigms to test map designs is indispensable.
