The big questionThe big question
• How do children learn meaning of words referring to abstract concepts?– Development of abstract concepts– Relationship of language to conceptual
development
• Focus here: number, time and space
![Page 3: The role of experience in children’s acquisition of space, time, and number words Elena Nicoladis University of Alberta](https://reader035.vdocument.in/reader035/viewer/2022062304/56649eb55503460f94bbd24e/html5/thumbnails/3.jpg)
How are number, space and How are number, space and time related?time related?
• Piaget vs. Kant
• I have colleagues who are interested in these concepts
• Children learn something about these concepts at an early age and their understanding/use of these concepts changes with age
![Page 4: The role of experience in children’s acquisition of space, time, and number words Elena Nicoladis University of Alberta](https://reader035.vdocument.in/reader035/viewer/2022062304/56649eb55503460f94bbd24e/html5/thumbnails/4.jpg)
OutlineOutline• Background
– Development of abstract concepts– Relationship between language and thought
in development
• Number• Time• Space• Do these have anything to do with each
other?
![Page 5: The role of experience in children’s acquisition of space, time, and number words Elena Nicoladis University of Alberta](https://reader035.vdocument.in/reader035/viewer/2022062304/56649eb55503460f94bbd24e/html5/thumbnails/5.jpg)
Development of abstract Development of abstract conceptsconcepts
• Piaget– Rational knowledge emerges from early
sensorimotor experience– For example, infants have implicit
understanding of causality– Therefore abstract concepts come from
concrete concepts– For example, temporal concepts come from
spatial concepts• Taller people are older
![Page 6: The role of experience in children’s acquisition of space, time, and number words Elena Nicoladis University of Alberta](https://reader035.vdocument.in/reader035/viewer/2022062304/56649eb55503460f94bbd24e/html5/thumbnails/6.jpg)
Development of abstract Development of abstract conceptsconcepts
• Since Piaget– Infancy research
• Infants react to perceptual stimuli on what could be described as abstract basis
• E.g., Can tell the difference between 1 and 2 visually; Can differentiate differently ordered images
– The function of the concepts could be important
• Particularly sociocultural function
![Page 7: The role of experience in children’s acquisition of space, time, and number words Elena Nicoladis University of Alberta](https://reader035.vdocument.in/reader035/viewer/2022062304/56649eb55503460f94bbd24e/html5/thumbnails/7.jpg)
Language and thought in Language and thought in developmentdevelopment
• Language does not necessarily map onto preverbal concepts
• For ex., Korean- and English-speaking children encode different aspects of spatial relations (Bowerman & Choi, 1990)
• Learning spatial language has to do with frequency in the input
![Page 8: The role of experience in children’s acquisition of space, time, and number words Elena Nicoladis University of Alberta](https://reader035.vdocument.in/reader035/viewer/2022062304/56649eb55503460f94bbd24e/html5/thumbnails/8.jpg)

How do children learn language How do children learn language referring to number, time and referring to number, time and
space?space?
• I’m going to start with words– Number words 1-100 (0)– Temporal words (particularly before and after)– Spatial word: Where
• Converging methodology– “Naturalistic” data– Experimental data
• Assumption: language use reflects thoughts
![Page 10: The role of experience in children’s acquisition of space, time, and number words Elena Nicoladis University of Alberta](https://reader035.vdocument.in/reader035/viewer/2022062304/56649eb55503460f94bbd24e/html5/thumbnails/10.jpg)

Number study conclusionsNumber study conclusions
• Children counted better in the language they knew better
• Suggesting that experience plays a role in learning number words
• We have not disproven language transparency-- it’s just later in development or less important than frequency
![Page 18: The role of experience in children’s acquisition of space, time, and number words Elena Nicoladis University of Alberta](https://reader035.vdocument.in/reader035/viewer/2022062304/56649eb55503460f94bbd24e/html5/thumbnails/18.jpg)
Learning number wordsLearning number words
• How does experience could play a role?– Frequency of hearing– Frequency of practicing– Earlier and/or higher numbers heard– Earlier and/or higher numbers used
• Study: looks at Chinese-speaking children in Hong Kong speaking with adults

Summary of results of number Summary of results of number studystudy
• Children and adults talk a lot about 1-3 and a fair bit about 4-10
• Higher numbers are infrequent
• Two hints about Chinese advantage– One child suddenly counted to 28 about a
month after his third birthday– Two older sisters wandered through,
assigning themselves math problems
![Page 22: The role of experience in children’s acquisition of space, time, and number words Elena Nicoladis University of Alberta](https://reader035.vdocument.in/reader035/viewer/2022062304/56649eb55503460f94bbd24e/html5/thumbnails/22.jpg)
Take-home message about Take-home message about numbersnumbers
• Experience matters with learning number words
• We don’t yet know what about experience makes a difference: probably academic setting helps with 11+– Peers?– Educators do something interesting with
numbers?

Time word backgroundTime word background
• Children are lousy with time words (concepts) before school age
• They confuse before/after, yesterday/tomorrow
• Four-year olds do not order events well
• Piaget argued that children learn time as metaphor for space– Most experiments used speed as dependent
measure
![Page 25: The role of experience in children’s acquisition of space, time, and number words Elena Nicoladis University of Alberta](https://reader035.vdocument.in/reader035/viewer/2022062304/56649eb55503460f94bbd24e/html5/thumbnails/25.jpg)
But…But…
• Do children learn about time as metaphor for space?
• Infants are sensitive to order of images as young as 8 months
• Marilyn Shatz has argued that children often learn a large category (like colour) and make mistakes within that category (blue for green)

• Time words in naturalistic conversation
• We looked at lots of temporal words (before, after, yesterday,today, tomorrow, hour, minute, day, week, year, etc.)
• English-speaking child (Abe) in interaction with his parents from 2;4 to 5 years

• Abe made very few errors in using time words
• Context of use of time words– Reconstructing past events for one parent– Negotiating future events
• One study showed that four-year olds are better at ordering everyday events than decontextualized story events

Summary of study 2Summary of study 2
• We showed that children are better at retrospective ordering than logical ordering
• They are not significantly better at prospective ordering than logical ordering on this task
![Page 36: The role of experience in children’s acquisition of space, time, and number words Elena Nicoladis University of Alberta](https://reader035.vdocument.in/reader035/viewer/2022062304/56649eb55503460f94bbd24e/html5/thumbnails/36.jpg)
Take-home messageTake-home message
• First-person experience can make a difference in understanding or performing on ordering task
• Piaget correct that logic follows personal experience in development
• Understanding time does not necessarily come from understanding space first
![Page 37: The role of experience in children’s acquisition of space, time, and number words Elena Nicoladis University of Alberta](https://reader035.vdocument.in/reader035/viewer/2022062304/56649eb55503460f94bbd24e/html5/thumbnails/37.jpg)

What does “where” mean?What does “where” mean?
• We know that children use “where” very early-- one of the earliest question words
• Studies of children’s nonverbal conceptualizations of space have shown that they tend to think of route earlier than location
• Easier to think along horizontal planes than vertical planes
![Page 39: The role of experience in children’s acquisition of space, time, and number words Elena Nicoladis University of Alberta](https://reader035.vdocument.in/reader035/viewer/2022062304/56649eb55503460f94bbd24e/html5/thumbnails/39.jpg)
Does “where” mean route or Does “where” mean route or location?location?
• 5 children interacting with parents at 2;0, 2;6, 3;0, 3;6
• Looked at children’s responses to parents’ use of “where”
• Transcripts already coded for children’s gesture use (including points)

• Children pointed more as parents asked more genuine “where” questions
• We could not distinguish whether children meant location or route – points usually were along both route and
location

• 42 children from 2-4 years
• Two questions about “where”:– Point to a hidden object– Point to rooms
• Same floor• Different floor
• Dependent measures: points to route vs. points to location

Summary of resultsSummary of results
• Children always point to the location of a hidden object
• Younger children point to route to rooms while older children (4 year olds) point to location
![Page 46: The role of experience in children’s acquisition of space, time, and number words Elena Nicoladis University of Alberta](https://reader035.vdocument.in/reader035/viewer/2022062304/56649eb55503460f94bbd24e/html5/thumbnails/46.jpg)
Interpretation of resultsInterpretation of results
• As children get older they think of rooms as locations
• They can think about large space AS IF it is small space
• Maybe around 4 years of age children could switch strategies of “where” responses– “Where is the bathroom?”

Learning abstract conceptsLearning abstract concepts• Socially interesting
– E.g., highly frequent
• First-person experience --> ability to use other perspectives– Time (before/after)– Space (late conceptualization of rooms as locations)
• Absolute --> relative– Number (90 = a lot) --> 96 vs. 97– Where = location of objects, route to rooms -->
location
![Page 49: The role of experience in children’s acquisition of space, time, and number words Elena Nicoladis University of Alberta](https://reader035.vdocument.in/reader035/viewer/2022062304/56649eb55503460f94bbd24e/html5/thumbnails/49.jpg)
Isn’t this just restating what Isn’t this just restating what Piaget said?Piaget said?
• Similarities– Importance of first-person perspective
N.b., I am not saying that children ARE egocentric
