Relative Distortions in Cognitive Maps in Sapporo

Distortions in Cognitive Maps

Cognitive maps refer to mental representations of maps or environments, as revealed in a variety of tasks. The simplest model of cognitive maps is that they are random degradations of real ones. Research using distance judgments, direction judgments, map recognition, map construction, and other information from memory for maps or environments suggests that distortions, rather than being random,...

Perceptually Induced Distortions in Cognitive Maps

Cities on a map that are directly connected by a route are judged closer than unconnected cities. This route effect has been attributed to memory distortions induced by the integration of map information with high-level knowledge about implications of route connections. However, depicted routes also connect cities visually, thereby creating a single visual object—which implies a perceptual basi...

Distortions in Memory for Maps

Evidence is presented for systematic errors in memory for real and artificial maps, local environments, and visual forms. These errors are attributed to two heuristics that are derived from principles of perceptual organization. Maps of countries or localities are conceived of as figures in backgrounds. Remembering the absolute location of figures is difficult, and is facilitated by remembering...
