Space Flashcards
what are topological relation?
e.g. on vs in, behind, next to
- describes simplest spatial relations
- relationship between figure and ground
- In English, usually the figure is smaller and the ground is larger
Piaget and Inhelder 1965 - Children’s spatial relations
- explored children’s conception of space
- suggested children’s spatial cognition emerges non-linguistically as child interacts with environment
- suggests that infants first acquire spatial concepts non linguistically then learn to map these concepts onto language
Baillargeon 1998 - Evidence for pre-linguistic spatial categories
- studies babies knowledge of spatial relations
- compared 3, 4.5-5.5 , 6.5 and 12.5 months old detection of spatial violations > measured surprise indicated by looking time
- scenes involved relational structures
- 3 month olds recognised need for contact with object for it to be supported
- 4.5-5.5 month olds recognised different types of contact
- 6.5 month olds surprised about object balancing with small amount of contact
12.5 month olds recognised more complex notions of gravity / force - ## showed infants have rich and developing knowledge of spatial relations before they know the specific words to talk about space in their language
Prelinguistic spatial concepts
- many scholars conclude that infants first acquire their spatial concepts non-linguistically
- infants then learn words which map onto linguistic concepts
- assumption that all babies have similar non-linguistic experience and therefore spatial concepts are universal
Are spatial concepts universal? Landau & Jackendoff 1993
- language describing space is limited - hypothesise this is due to there being so few prepositions because the class of spatial relations available to be expressed in language is extremely limited
Frames of reference (FOR)
- describes coordinate systems used to compute and specify the location of objects with respect to other objects (Majid 2004)
- three common frames used across languages:
- relative > relying on an observer/viewpoint
-intrinsic > where one element of the scene has facets
-absolute > cardinal directions
Levinson 2003
Frames of reference - cross linguistic data - English v Guugu Yimithirr
- cross linguistic data shows there is variation in when and how often different cultures use different frames of reference
- ppts asked to describe a simple scene
- English speakers often use intrinsic or relative frames of reference when describing spatial relationships in a table top space
- In contrast Guugu Yimithirr speakers use an absolute FoR
- Guugu Yimithirr > indigenous Australian
Predicting FoR - Majid et al 2004
- mapped prevalence of different FoR across languages
- tested whether ecology, dwelling type or subsistence style predicted frames of reference
- some evidence suggested that languages spoken in urban environments were more likely to have a relative frame of reference
- did not find evidence that environment or subsistence type predicted frame of reference
Topographic Correspondence Theory - Palmer 2015
- predicts that salient aspects of the environment determine/influence FoR
- supported by the fact that people in urban environments are more likely to use a relative FoR, rural environments more likely to use absolute
Challenges for topographic correspondance thoery
- weak support
- contradicted by the fact that speakers in both mountainous and non-mountainous regions in Tztetal and Hai//om use absolute frames of reference (despite differences in environmental saliency) Brown 2012
- Jahai live in mountainous regions but use intrinsic frames of reference
Relative frame of reference
-relies on a viewpoint / observer
- e.g. she is on my right (as opposed to your left)
Levinson 1996 - Frames of reference & Molyneux question
- investigates relationship between spatial language and perception across language/culture
- different ways languages encode spatial relationships and whether these linguistic differences impact interpretation of spatial info visually
- examined languages using different FoR > distinguishing between egocentric and allocentric frames
- ## looked at ppts ability to match visual stimuli with corresponding spatial descriptions and vice vera - investigated speed and accuracy of these cognitive processes
Molyneux’s Question
- asks whether a blind person from birth, upon gaining sight, would be able to immediately recognise and associate visual perception with previously known tactile or spatial concepts
Egocentric FoR
An egocentric frame of reference describes spatial relationships in relation to the speaker’s own body. For example, in English, one might say, “The book is to the left of me.”
Allocentric FoR
In contrast, an allocentric frame of reference describes spatial relationships using external, objective landmarks. For example, in Tzeltal, a Mayan language, one might say, “The book is to the west of the table.”
