I am interested in the dynamics that both hinder and facilitate early word learning in children. Currently I am studying how children learn words in environments where there are multiple people talking. While it is not uncommon for children to learn words in a complex auditory environment, the extent to which this complexity hinders or helps the development of language still remains uncertain.

I am interested in the differences in acquiring first and second languages, particularly with respect to individual variability in learning. How does adults’ learning differ from children’s? Why is it that some adults seem to have a harder time than others when they try to learn a second language and how does this ability relate to other cognitive skills?

As any parent knows, infants learn an incredible number of words in their first two years of life. Their word knowledge, however, consists of more than just associations between a label (i.e."dog"), and an object (i.e. furry, slobbery four-legged animal). I am interested in how infants learn the complex knowledge that makes up their semantic network. Currently, I am working on projects looking at both early semantic knowledge and how that knowledge is learned.

I am interested in how infants use phonological cues in language learning. My current research focuses on how babies and adults behave when they are in language environments that are linguistically different from English, i.e., a tone language. I am co-advised by Jenny Saffran and Mark Seidenberg.

How do children acquire their native language? My research focuses on the kinds of learning abilities required to master the complexities of language. Three broad issues characterize my work. One line of research asks what kinds of learning emerge in infancy. A second line of research probes the biases that shape human learning abilities, and the relationship between these biases and the structure of human languages. A third issue concerns the extent to which the learning abilities underlying this process are specifically tailored for language acquisition. Related research concerns infant music perception, and the relationship between music and language learning.

I am a graduate student in the Department of Communicative Disorders, working with Susan Ellis Weismer and Jenny Saffran. My research focuses on characterizing the learning mechanisms that underlie atypical language acquisition, in hopes of better understanding why some children have such difficulty acquiring language. I am interested in a variety of clinical populations, including children with autism spectrum disorders and children with specific language delays. As a licensed and certified speech-language pathologist, I am also interested in delineating the impact of adult language input on language development in children with developmental delays. My dissertation work focuses on statistical word learning and non-social visual attention in children with autism, using real-time eye-gaze methodology.

Children are amazing word learners, yet it is unclear what the ‘know’ in their

memory for a new name. For example, when a child learns the word ‘banana’,

has she learned something about its color, its shape, or both? Furthermore, little is known about individual differences in this knowledge, and what drives such differences: for example, do differences in existing vocabulary knowledge lead to differences in what children remember about new words? My research in the Infant Learning Lab explores children’s attention to and memory for objects that they can already name (e.g. ‘apple’) and of novel objects for which we teach children the name (e.g. ‘wug’). I am co-advised by Jenny Saffran, Gary Lupyan, and Mark Seidenberg.

Rachel Raczynski, Undergraduate Student

I am currently a senior majoring in Psychology. I love working with children of all ages, and am very interested to learn more about how they acquire and understand language. Working in the Infant Learning Lab is a great opportunity for anyone who's interested in the subject to get some first-hand research experience. In the future, I would love to work with children in some sort of school setting, as either a school psychologist or guidance counselor. Until then, I'm enjoying every moment of my experience here at the lab!

Shelby Adler, Undergraduate Student

I am a senior majoring in psychology. I plan to go grad school or med school in the future. I have always loved kids, but what really sparked my interest was working with a kid going into kindergarten who had autism during the summer of my freshman year. I am very excited to learn more about children and I know I will get a lot out of working here!

I am interested in the processes that children use to acquire language, and how these are different or similar in children who are developing atypically. I study grammatical and lexical development in children with autism spectrum disorders, and how their language is influenced by other aspects of their development (e.g., cognitive abilities), as well as their linguistic environment (e.g., parents’ speech and gestures). I am co-advised by Jenny Saffran and Susan Ellis Weismer.

Word learning involves more than just being able to identify an object.  For example, apples can be eaten, are fruits, grow on trees, and come in different colors.  I am interested in studying how children learn these other dimensions of a word’s meaning.  My current work focuses on whether children have difficulty flexibly shifting between these different dimensions of a word’s meaning and if this difficulty relates to other developing cognitive skills like attentional control.

Children learn about the world in a rich social environment where they are constantly interacting with other adults and children. How does growing up in a social world help children learn language? How does social interaction structure language input and motivate children to learn to communicate using language? In my research, I explore how social context and children's learning mechanisms and biases work together in language development. I am co-advised by Jenny Saffran and Gary Lupyan.

I am a senior double majoring in Psychology and Communication Sciences and Disorders. I am very excited to work in the Infant Learning Lab because it combines interests from both of my majors. After graduating, I hope to attend graduate school to earn a degree in speech-language pathology, and eventually I would like to work as a speech-language pathologist in an elementary school setting. I love working with children and am looking forward to learning more about how they learn aspects of language!

Janine Mathee, Undergraduate Student

I am a junior this year, majoring in Communication Sciences and Disorders with a certificate in Education and Educational Services. I hope to eventually go on to grad school and become a Speech-Language Pathologist, and of course work with kids! My main interest in speech and hearing sciences has to do with the incredible and fascinating ways that children acquire language. And I'm especially interested in how children with intellectual/developmental disabilities and/or hearing loss overcome those challenges and learn language in their own unique ways. I'm looking forward to learning from everyone in this lab and from these fascinating children and their incredible abilities.

Pang Xiong, Undergraduate Student

I am a senior double majoring in Psychology and Communicative Sciences and Disorders. I became interested in these topics when I discovered my little brother had autism. In the future, I want to work and play with children with learning or speech disorders. I love learning about child psychology, and additionally, little babies just astound me with the way they explore and experiment with the bright new world. In my eyes, they're the world's best scientists!

Marissa Schuh, Undergraduate Student

I am a senior studying Communication Sciences and Disorders with hopes of attending graduate school for Speech Language Pathology. After graduate school, I would like to work within a school setting as I have a passion for working with children and learning from them. Within the field of Communication Sciences and Disorders, I am interested in child language development and how household factors as well as parental factors play a role in that development. I also have an interest in language development in children with various developmental or cognitive disabilities, and the role that different therapies can play in their development. I look forward to expanding my knowledge about child language development during my time here in the lab!

Learning about the world requires making sense of the large amount of information that surrounds us. How do we attend to the right kinds of patterns that promote learning? How does this process change how we learn new information?  My research focuses on understanding the interaction between attention and learning processes in infants, children, and adults. I study this interaction in the context of word learning, and by examining how learning experience and development change attentional abilities.

Allison Hare, Undergraduate Student

I am currently a sophomore planning to major in Psychology and Biology, possibly with a certificate in global health. I hope to go to graduate school in a psychology- or biology-related discipline one day, or to medical school to become a pediatrician. I have always loved working with children in many areas of my life including volunteering at schools, day cares, churches, or children’s hospitals, so the Infant Learning Lab seemed like the perfect opportunity to combine my interest in psychology with my love of children. I hope to make the most of my time here at the lab both through learning as much as I can about how children accrue knowledge of language and their language abilities, as well as contributing to what we already know about this area of developmental psychology.

Sarah Oakley, Undergraduate Student

I am a sophomore majoring in Psychology with a certificate in Criminal Justice. I plan on attending graduate school in the future, and also hope to enter a field in which I can interact with children on a regular basis.
