Here are short descriptions of some past studies and their results that have been published from the Centre for Child Studies. If you have taken part in our studies, we hope you are able find out what we were able to discover as a result of your participation.
As of 2013, we now try to have a press release for most new results from the lab, and announce this on social media such as twitter. Thus new results from the lab will be updated largely in our Centre in the News section with accompanying links there.
PDF copies of all the studies listed below and others conducted by Dr. Daniela O'Neill are available in the section published papers of this website.
Young children's ability to step into the shoes and minds of characters in stories
In a series of ongoing studies, we looked at how very young children, long before they can read, are able to step into the shoes and minds of characters in stories. As adults, we do this so effortlessly, we really are hardly aware of it at all. Much research with adults has shown that, as we read or listen to a story, we build up what are called "situation models" or "mental models" in our mind of the setting, events and even psychological states of characters in stories. But almost nothing is known about whether children share this narrative ability, and if so, when does it emerge? Our studies are showing that children share this ability from an early age - as early as 3 and 4 years old. We believe these studies may help to shed new light on our understanding of processes involved in reading comprehension. Reading comprehension has received much less study than the acquisition of reading itself. Yet reading comprehension can prove to be an area of difficulty for children once they enter school. We are hoping, through these studies, to learn more about what is involved in the development of reading comprehension.
This work has been reported in a number of media articles that have done a great job of summarizing the study. Here are links to some of them that appear in the Centre News section of this website.

How do 4-year-olds begin conversations with each other?
In this study, we were interested in how, in a naturalistic setting - the snackroom of a preschool - 4-year-old children would attempt to begin conversations with each other. What topics would they try to initiate? Would these topics include only aspects of the physical setting (e.g., talk about toys, food) or would they also include topics about mental states (e.g., what they are thinking about, what they know, what they are seeing, hearing). We collected a large database of videotaped conversations (over 40 sessions of more than 45 minutes of snackroom talk) which we transcribed and then analyzed. We learned that beginning a conversation with peers is not easy for children! Along with a detailed qualitative analysis of the types of topics they tried to initiate, the paper provides lots of fun examples taken from the transcripts!

A link between preschoolers' storytelling abilities and their later mathematical ability
This study, in which we found a predictive relation between 3- and 4-year-olds' abiity to take the perspective of characters in a story telling task, and their later mathematical ability two years later, has been reported on in many media articles, some of which have done a much better job than we could here of summarizing the study and hitting the highlights! Here are links to some of them that appear in Centre News!

Preschoolers talk about future situations
In this study, we were interested in when children first develop the ability to really project themselves into the future and anticipate a future situation. To study this, we had children take part in a "pretend trip" task. Children were shown some items, such as juice, bandaids, sunglasses, and money and were asked to choose three things that they might need to bring them along on a trip. After choosing an item, the children were asked by Elmo the puppet why they were bringing the item on a trip. We found that although older 3-year-olds answered Elmo's questions with explanations like "I might get hurt (that's why I need bandaids), " this was not what younger 3-year-olds did. The younger children did not appear to be able to project themselves into the future in the same way. Their explanations were much more likely to be present-oriented rather than future-oriented. So, they might explain their choice to take bandaids by saying, "I like them." So, it seems from this first study that children's ability to project themselves into the future and anticipate future situations is developing in children's fourth year of life. (This study was conducted by Cristina Atance and Daniela O'Neill and published in 2005 in First Language, 1, 5-18. Further related studies were also published in 2005 in Learning and Motivation, 36, 126-144. Dr. Cristina Atance has continued this work in her own research lab as a Professor at the University of Ottawa.)
Feeling sponginess: The importance of gesture in two-year-old children's acquisition of adjectives
Do gestures help children to learn the meaning of new word? This is the question we set out to answer in this study. The new words we used were adjectives. Adjectives are interesting words because their meaning can be quite difficult to figure out. For example, if I show you a teddy bear and say "This is a daxxy bear," what could I mean? This is the type of situation that young children learning language face all the time - they are hearing a new word and must try and figure out what the speaker is talking about. Does "daxxy" mean brown? fat? soft? hairy? heavy? or what?
In this study we looked at whether children as young as 2 years of age might pay attention to the gestures a speaker uses when talking about adjectives in order to figure out what they mean. Children were shown 5 toys and for each toy a new adjective term - "roughy," "spongy," "lumpy," "spiny" or "fleecy" was used to describe it.
The key thing was, that for one group of 20 children, we just pointed to the toy as we said "This is a spongy cow." But for another group of 20 children we used a more descriptive gesture such as squeezing the cow as we said "This is a spongy cow." Would the type of gesture make a difference to children this young? Would they learn the meaning of "spongy" better in one case?
The answer was clearly "YES!" Children given the more descriptive gesture, were better able later to choose another toy that was also "spongy" than the children only given a point gesture.
Interestingly, the children given only the point gesture were much more likely to ask whether the other similar toy they had chose possessed the relevant property: "Is this the spongy pig?" And, when they were first learning the meaning of spongy, they were much more likely to talk about other properties of the toy. It was as though they were saying to themselves: "What could spongy mean? Pink? Has a tail? Fat?" But the children given the more descriptive gesture did not do this. We believe this is because the more descriptive gesture allowed them to zoom in on the right property and they could just concentrate on learning the new word! So gestures do matter, even for children only 2 years old! (This study was conducted by Daniela K. O'Neill, Jane Topolovec and Wilma Stern-Cavalcante and published in 2002 in the Journal of Cognition and Development, 3, 243-277).
Preschool children's difficulty understanding the kinds of information we gain through our five senses
In this set of studies, we explored what 3- and 4-year-old children understand about how each of five senses can lead to different types of knowledge. For example, from seeing we can tell that something is blue, but we can't do that from feeling something.
In Study 1, the children engaged in 5 scenarios in which they could only perform 1 sensory action to identify the property of an object (e.g., color, smell). For example, they were able to smell a colourless liquid. After performing the action, children were asked what it's property was (e.g., strawberry smelling) and how they found out the property (e.g., by smelling) and to show the experimenter how they found it out (e.g., to sniff). Children were also asked, using a Mr. Potato Head doll, to pick the sensory organ (e.g., his nose) that the doll would need to use to find out the same property.
In Study 2, children were presented with 5 Mr. Potato Heads, each sporting only 1 sensory organ (e.g., Mr. Nose, Mr. Eyes, Mr. Ears, Mr. Hands, and Mr. Mouth) and asked which Mr. Potato Head could find out the property in question.
Overall, we found that 3-year-olds find these kinds of questions very, very hard! They can tell you that "eyes are for seeing" and "noses are for smelling," but if they have to consider carefully how they came to know that something was "strawberry smelling," it's much harder for them. Strikingly, by 4 years of age, children find these questions easy! So, we found out that between 3 and 4 years of age, children develop the understanding of what kinds of knowledge our different senses can provide us with. (This study was conducted by Daniela K. O'Neill and Selena Chong and published in 2001 in Child Development, 72, 803-815.)
"Maybe my daddy give me a big piano:" The development of children's use of modals to express uncertainty
This study was conducted using an online database of child language transcripts available to researchers called Child Language Data Exchange System (CHILDES) developed and maintained by Dr. Brian MacWhinney of Carnegie Mellon University. We used the database to look at how 10 children between the age of 24 to 59 months began to use the words "maybe", "possibly", "probably", and "might" (modal terms as they are known to researchers). These may seem like unusual words to study, but they are very interesting words because we use them to talk about uncertainty and we were interested in learning more about how children begin to understand uncertainty. Uncertainty is a fact of life and a very important part of our understanding of the future as the future is always uncertain. And children's developing understanding of the future is something that we have been studying in the lab.
By looking at the transcripts in the CHILDES database, we were able to develop a way to "code" them and see whether these words were, for example, being used to talk about things in the present, in the past, in the future; about people or about physical objects, and so on. This allowed us to say something overall about the contexts in which children are using these words when they first start using them and as they get older.
We discovered that children first talked about uncertainty using "maybe" and "probably" in connection with ongoing events in the physical world and with respect to future intentions, usually of the self. Next, children were able to use these words to talk about uncertainty with respect to future situations. After about 42 months of age, children began to use "might" much more often, especially to talk about "things that might happen" in the future. So by 3 years of age, children are clearly already thinking and talking about things in the future and are showing the ability to talk about hypothetical situations that will become very important to the development of scientific thinking. (This study was conducted by Daniela K. O'Neill and Cristina M. Atance and was published in 2000 in First Language, 2029-52.)
Two-year-old children's sensitivity to the referential (in)efficacy of their own pointing gestures
This study helped us to learn more about how young 2-year-olds adapt their communication for listeners. In this study, we were interested in finding out whether 2-year-old children can recognize that in some situations a pointing gesture is not enough specify clearly an object that they want, and will choose to name the object verbally as well.
The 2-year-olds in this study were told that they would be playing a game in which they would find some hidden stickers. The stickers were hidden inside plastic toy animals that had an opening in the bottom in which a sticker could be placed. The children sat at a small table with the researcher to their right and their mother to their left. The researcher then hid a sticker in one of two toy animals. The 2-year-olds were able to watch which toy the sticker was hidden in, but their mother was asked to close her eyes during the hiding of the sticker.
The two toys were then placed in one of two ways at the far end of the table, out of reach of the children, as shown in the pictures below.
In Situation A, the toys were placed far apart on the table.
In Situation B, the toys were placed very close together.
Once the toys had been placed at the far end of the table, the mothers were asked to open their eyes and the children could tell her which toy they wanted.
In Situation A, we thought that most children would simply point to the toy they wanted. And this is indeed what our 2-year-old children usually did.
But, we were really more interested in seeing what the children would do in Situation B. In this situation, if children just pointed to the toy, it was not possible for their mother to know which toy they wanted, because the toys were too small and too far away (we purposely designed it this way!). What children had to do to make clear to their mom which toy they wanted was to use their words and tell her "I want the dog" or "I want the pig." And this is exactly what the 2-year-olds did--and they only did this in Situation B and not Situation A.
So, this study helped us to learn more about how 2-year-olds really are much more sophisticated communicators than we might previously have thought. In this study, they recognized when their gestures could not specify what they wanted clearly enough and adapted their communication accordingly by naming the toy animal. (This study was conducted by Daniela K. O'Neill & Jane C. Topolovec and was published in 2001 in the Journal of Child Language, 28, 1-28.)
Noticing and commenting on what's new: differences and similarities among 22-month-old typically developing children, children with Down syndrome, and children with autism
In this study we were interested in how typically developing children, children with Down syndrome, and children with autism might comment about "new" objects.
The 20 typically developing children taking part were 22 months old. The 11 children with Down syndrome and 10 children with autism taking part were all at the 1- and 2-word stage.
All the children were given 8 series of 4 toys to explore. In each series, the first 3 toys (i.e., Trials 1 to 3) were identical, but the fourth toy (i.e., Trial 4) differed on a property or in identity. For example, in one series children were given the following four toys: small yellow duck, small yellow duck, small yellow duck, BIG yellow duck.
The children sat beside their mother and the experimenter while exploring the toys. We were particularly interested what children would do when they received the first new toy and the fourth toy that was different. For example, would the children be more likely to explore the toy when it was "new"?
We found that the children with Down syndrome responded very similarly to the new toys as typically developing children did - exploring the new toys for longer and communicating more often about them than the "old" toys in the middle two trials. The children with Down syndrome were more likely to have difficulty maintaining conversation with both the experimenter and their mother about the toys (triadic communication as it is sometimes called), tending to talk mainly with experimenter. The children with autism showed a different reaction to the toys than both other groups of children. They explored the toys for much less time overall, and did not show a tendency to explore or communicate about them more often when they were "new" versus "old."
These findings suggest that typically, by 22 months of age and at very early language levels, children already show an understanding of that fact that we tend to talk to other people more about "new" things than "old" things (so as not to bore them, for one reason!). This is a pragmatic aspect of language use however, that is much more difficult for children with autism to understand. (This study was conducted by Daniela K. O'Neill & Francesca G. Happé and was published in 2000 in Developmental Science, 3, 457-478)
How children use gestures to help their storytelling
In this particular study, we were interested in looking at preschool children's early storytelling ability and how they use their gestures and voices to help tell a story. Storytelling is a very important ability, for as the eminent psychologist Jerome Bruner has argued so well, stories are not just child's play but serve as our means of understanding the world we live in.
In this study, children were shown a picture book that told a story without any text. Children first looked through the story, and then they were asked to tell the story to Ernie the puppet who had never heard the story before. Children were excited to tell Ernie the story and did a great job. We videotaped children as they told the story. By videotaping the story, after children had taken part, we could write out their stories and also see what gestures they used and how they used their voice to mimic some of the characters in the story.
For a long time, we have known that young preschool children have difficulty, when telling a story, to clearly identify all the characters. For example, they usually over-use pronouns (he/she/it/them/they) when instead they should be more specific and use a more specific term like "the girl" or "Janet." And in our study, we found the same difficulty. 4-year-olds overused pronouns about 50% of the time, and 3-year-olds overused pronouns almost all the time - about 75% of the time. We could see this clearly when we wrote out children's stories.
But when we were also able to take into account, from the videotapes, children's gestures (e.g., their points to a specific character in the picture on a page) and their use of their "pretend" voices to act out what a character was saying, we realized that 3-year-olds were being much clearer than it looked at first. By using gestures to point to characters in the pictures and by adopting the "voices" of different characters (as children often do when pretend playing), 3-year-olds made it quite clear who they were meaning to talk about.
Indeed, when all the analyses were done, through using their gestures and voices, 3-year-olds were able, just like 4-year-olds, to clearly reference the characters in their stories about 50% of the time. Referencing story characters is clearly a difficult task for children, as 4-year-olds still have a way to go, given that 50% of the time their references are still unclear. Four-year-olds don't use gestures and voicing as much though (perhaps they think the gestures are "babyish"?).
Telling a story is a tremendous linguistic and cognitive achievement, and our studies are helping us to better understand how children progress as storytellers and what they they have to learn to do it. These studies are also making us aware of important ways in which children's stories are not yet like adult stories, and how much we should reasonably expect children to be able to do when telling stories. Having such benchmarks for children who are developing typically may be especially useful for professionals working with children with delays in their language and related skills such as storytelling.
