Human Cognition in the Geographic Domain David M. Mark Department of Geography, UB Spatial Cognition • Spatial cognition is a well established field in cognitive psychology • Topics include: Mental rotation; position recall; maze tracing • Landau & Jackendoff: “What and Where in Language and Cognition” – Different systems in the brain for handling object categories (what) and spatial locations (where) Geography • Geography is a discipline that studies the Earth’s surface: – What is where? – Why are things where they are? – Where will things be in the future? – Where should they be? • Is Geographic cognition different from spatial cognition? – Probably… What is meant by “Geographic”? • Class participation: what do you think? • Not exactly a synonym for spatial • Borderline cases – iceberg, supertanker, tree, building, … • Geographic: A subset of spatial, mesoscopic reality, distances > 20 m Is the "geographic domain" a coherent subdomain of reality? • How would we even start to answer that? • Is the geographic domain cognitively distinct? • There is lots of evidence that geographic space is dealt with differently than the table-top world of manipulable objects, although there must be a transition between them Granö • Johannes Granö was a geographer in Finland, who wrote a book called “Pure Geography” in the 1930s • He claimed that the subject matter of Geography is, or should be, the human perceptual environment • He proposed that the human perceptual environment idea is divided into two zones: the proximity and the landscape • The proximity is a zone within about 20 meters (70 feet), that is perceived as 3D and multisensory; • The landscape is farther away, largely 2D (projected image) and mainly visual • Landscape in Granö's sense is close to what we call geographic Major Topics in Geographic Cognition Research • Wayfinding and navigation • Mental maps and knowledge of geographic configurations • Spatial Relations • Spatial Reference Frames • Human-computer Interaction for GIS • Geographic Entities and their Categories Wayfinding and Navigation • Landmarks; distance and direction • Possible gender-related differences • • • • Other species (rats, pigeons, honeybees) Giving directions Vehicle navigation systems Links to behavioral geography, trying to understand choice of shops, homes ‘Mental Maps’ and Knowledge of Geographic Phenomena Spatial Relations • Geographic space is essentially 2-D • Road-park experiments (see below) • Inside, outside, enters, crosses • perhaps two more, goes to and goes along • Why those 4 (or 6) Numbers of ‘Different’ Spatial Relations • The 9-intersection model defines – 8 distinct spatial relations between two regions – 33 distinct spatial relations between two unbranched lines – 19 spatial relations between an unbranched line and a region 8 relations between two regions The 19 line-region relations Spatial Reference Frames • Several different types of Reference Frames – Viewer/speaker centered (in front of the tree) – Object centered (in front of the car) – Absolute/geographic • A significant minority of cultures and languages use 'geographic' reference frames indoors • This does this mean that think about space differently Human-Computer Interaction for GIS • Are HCI issues different for the geographic / GIS domain? • Perhaps there are no unique problems in the intersection • The space-for-space problem might be one? Geographic Entities and Their Categories • A really different aspect of the geographic domain is the preponderance of landforms, features (shape-based parts) of other things • The only geographical detached objects (JJ Gibson) are whole planets "Do mountains exist?" • The individuation or delimitation problem • The gradation problem • The categories (eg., mountain vs. hill) Hills and Mountains • Mountain: 1. a. A large natural elevation of the earth's surface, esp. one high and steep in form (larger and higher than a hill) (OED) Hills and Mountains • Hill: 1. a. A natural elevation of the earth's surface … after the introduction of the word ‘mountain’ [into English], gradually restricted to heights of less elevation; … (OED) Hills and Mountains: Not Simply a Matter of Size! • Hill: “a more rounded and less rugged outline is also usually connoted by the name” (OED) Hill ?? Mountain “Finger Rock” • • • • • #76 “Shiprock” 4 B For features too small to be ‘mountains’, yet too jagged to be ‘hills’, Shiprock area English relies on other terms, such as rock, butte, peak, mesa, etc.… buttes/ monoliths “Mitten Buttes” “Picacho Peak” P9250035 Thank you for your attention!
