Children encounter novel entities frequently.
For all such entities, children must make reality status judgments.
For many of these entities, reality status is immediately apparent (e.g., the family dog).
However for many others, it is not; children very often hear about novel entities from other people and do not have the opportunity to interact with these entities.

How do children determine reality status? They use the context in which the novel
entity is encountered.◦ Woolley & Van Reet, 2006◦ Cox & Woolley, 2009
They weigh evidence for and against its existence.◦ Woolley, Boerger, & Markman, 2004◦ Tullos & Woolley, 2009
They ask questions.◦ Baxter & Sabbagh, 2003

What might children pick up from listening to direct statements and/or conversations?
![Page 5: Jacqueline Woolley Lili Ma University of Texas. Children encounter novel entities frequently. For all such entities, children must make reality status](https://reader035.vdocument.in/reader035/viewer/2022070404/56649f345503460f94c525ac/html5/thumbnails/5.jpg)
Similarities in how we talk about real and not-real entities
Real entities with sensory affordances:◦ Existence is assumed in conversation.
“Put your book down on the table.” Real entities without sensory affordances:
◦ Existence is also assumed in conversation. “Wash your hands; they’re covered with germs!”
Not-real entities◦ Existence is also assumed in conversation.
“What did Santa Claus bring you this year?”

Not-real entities (or entities for which belief varies): “She still believes in Santa Claus.” “We believe in God.” “Fairies are not in real life.”
Real entities (belief does not vary):We do not say, “I believe in the garbage
man” or “cows are in real life.”

Do children use these cues to figure out reality status?◦ To what extent can children learn about reality
status simply from listening to talk? When do children become aware that we
imply reality status in the way we talk about things?◦ What is the relative effectiveness of explicit
statements of belief (e.g., “civets are real; I believe in civets”) versus simple inclusions in everyday talk (e.g., “I almost ran over a civet today”) in conveying belief?
![Page 8: Jacqueline Woolley Lili Ma University of Texas. Children encounter novel entities frequently. For all such entities, children must make reality status](https://reader035.vdocument.in/reader035/viewer/2022070404/56649f345503460f94c525ac/html5/thumbnails/8.jpg)
Explicit belief◦ Do you know about civets? They are real. I believe in
civets.”
Explicit denial◦ Do you know about civets? They’re not real. I don’t
believe in civets.”
Implicit belief: Property statement + knowledge claim◦ Do you know about civets? They can move really fast. I
know a lot about civets.”
Implicit belief: Involvement in event◦ “Do you know what happened? I almost ran over a civet
when I was driving home! I almost hit the civet !”

Goals:◦ To make the situation more naturalistic and to
increase input Children can learn novel words through “overhearing”;
can they also learn about novel entities this way?◦ To include a clear case in which we could
demonstrate that children were willing to say that something was real
◦ To explore decrease between 5 and 7 on explicit belief trials Due to recognition of subjective nature of belief? Due to skepticism regarding experimental procedure?

3-year-olds not using talk, except for negative statements.◦ However exploratory follow-up analyses suggest
competence
Development between 5 and 7 in use of both explicit and implicit statements◦ Explore changes between 5 and 7
Are 5’s less competent in picking up conversational cues?
Are they more reluctant to accept testimony generally?

Conclusions and future research (cont.)
No clear evidence that children recognize that explicit expressions of belief imply ambiguity about reality status
Include older age groups (9-year-olds…) Validate intuitions with an adult sample
