The lab explores the development and evolution of communication through behavioral experiments with babies and children.
AboutAbout the lab
Exploring the development and evolution of communication.
The Comparative Developmental Psychology Lab aims to clarify the development of communication and its foundations through behavioral experiments grounded in natural science.
To approach both development unique to humans and development shared across species, the lab conducts comparative developmental and comparative behavioral research informed by evolutionary perspectives and theories.
As a foundation for research on infants and young children, the lab runs a volunteer panel named the "Kyushu University Baby Researchers" and conducts studies at the "Baby Lab" on campus.
In cooperation with other research institutions, the lab also conducts experimental research on non-human primates such as chimpanzees.
Key terms
- Baby Researchers
- A volunteer program in which infants and their parents register as research participants. The lab has run it since 2003
- Comparative behavioral science
- A research approach that compares the behavior of humans and animals across species and considers how that behavior comes about
- Onomatopoeia
- Words that imitate sounds or express manner or state; this includes both onomatopoeic and mimetic words

ResearchResearch themes
Based on a system in which infants and their parents register as "Baby Researchers," the lab carries out multiple research projects jointly with graduate and undergraduate students. In parallel, it conducts experimental analyses of nonverbal communication behavior in adults.
How people imitate sounds with words
When putting into words sounds that have no established expression, such as onomatopoeia, do adults and children express them differently? Focusing on speech sounds, the lab examines this question with children aged 3 to 10.
How people choose cooperative partners
Choosing a partner well is important for cooperation. In a game setting, the lab examined what kinds of partners are chosen from among others who differ in cooperativeness and ability, studying adults and children aged 5 to 10.
Interpreting ambiguous utterances
Ambiguous communication works by reading the other person's intentions and filling in what is not stated explicitly through inference. The lab is examining how adults and children aged 7 to 10 interpret ambiguity.
