What is wordform recognition? Before they can even consider learning what words mean, infants need to be able to recognize the consistent way that words sound, even though the same word can sound super different each time it’s said! Take a listen to this audio recording of all the times a baby heard other people […]

Zoom into language development: How does an online study with infants work?
As everything closed during the COVID-19 lockdowns, of course, our lab was no exception. With no safe way of further testing children and parents in our lab facilities, we had to bring the lab to our participants. With online yoga classes and family gatherings, we thought to ourselves: shouldn’t that work for our experiments as […]

Randomized control trials help scientists know if interventions can influence child development.
Have you ever wondered how researchers determine whether a treatment works as expected? One way to achieve this goal is through intervention research. Simply put, in intervention research, scientists and medical practitioners give a new treatment (or intervention) to a group of people and measure if the outcome is different from a group who didn’t […]

How do we measure young children’s vocabulary size?
When studying early childhood language, researchers often want to know children’s vocabulary size, but it can be difficult for researchers to get a truly accurate idea of what children words children know. We can’t tell what’s in their usual vocabulary just from interacting with them during a research visit, since we are only around them […]

One way to research children’s development is through elicitation tasks.
Elicitation tasks are a category of research methods that refers to any technique aiming to bring out responses from people. It allows researchers to gain insights into what participants think and know. This method is used in a wide range of disciplines, from cognitive science to behavioral economics. Common elicitation tasks include questionnaires, interviews, and brainstorming […]

Observing how something changes over time: longitudinal studies
Longitudinal studies, like their name, are long. Often in research, scientists are curious about how time will affect a particular aspect of life. In order to study this relationship, they might create a longitudinal study. A longitudinal study is the study of the same group of adult or child participants over a period of time. […]

Scientists can see your baby’s brainwaves! Using EEG to study language processing
Studying language through infants’ brainwaves. How babies learn language is deeply fascinating. Many experimental methods can help us understand when and how they acquire new words. In earlier posts, we discussed using behavioral methods and observational methods. A third type of method that is used to study word learning directly investigates how children’s (or adult’s) […]

Important EEG Waves
When we measure baby brainwaves, what do we measure and what does it mean? When scientists measure brainwaves, they find a lot of them happening at different times. Scientists call these waves components, but we will continue to call them waves in this post. Some of the waves show up […]

Scientists can’t ask babies what they think, but we can see where they look.
Where infants look can tell us what they know about the world. As any parent knows, infants cannot readily tell you what they want or need. This also means that they cannot directly express what they know. For developmental psychologists, who are often interested in what infants know when, this can be pretty challenging. So […]

Babies on their home turf: using observational methods to study development
How do scientists learn what babies know? Babies learn language from the language (or languages) they experience in the world around them. But what is early language experience actually like for babies? Observational methods can give us a glimpse into children’s everyday lives – what they hear, see, and say. One approach uses naturalistic recordings […]
