What is the format of the mental representations that store information, and what computations can we perform over these representations? Our research explores answers to these questions for the case of the concept “individual”. This work both draws from and unites research in numerical cognition, object-based attention, and short-term memory. Our research centers on infants and young children. By examining key points in development we can gain insight into the role played by a set of representations as new knowledge is acquired, and as new knowledge structures are created.

Professor Halberda's research focuses on two main topics. The first is an interest in language acquisition and the possibility that logical deductive inference may play a role in the learning of new words. The second is an interest in the organization of attention and the connection of mind to world. Students in the lab work with infants, children and adults using classic anticipatory-looking paradigms and eye-tracking as well as computational modeling.

Andrea Stevenson
Lab Coordinator
asteve20@jhu.edu

Hi! My name is Andrea Stevenson. I graduated from the University of Western Ontario, Canada with an Honors Bachelor of Arts in Psychology and a Bachelor of Education. For three years, I taught at the elementary level. Currently, I am working as the lab coordinator in the Lab for Child Development in order to enhance my knowledge of how children learn and understand.

Broadly, I am interested in object and number representation, as well as working memory capacity, in infants and young children. Specifically, I have focused on the distinction between infants' representations of the types of entities we typically associate with the word "object" such as cups or balls, versus their representations of non-solid and non-cohesive entities such as sand. I also have a secondary research program that addresses the role of spatial language in toddlers' and young children's ability to reason about hidden objects and scenes.

I am currently finishing my Ph.D. in the Laboratory for Child Development here at Johns Hopkins. My dissertation is examining the “what” and “how many” of working memory in infants. For instance, if young infants see a cat, a shoe, and a spoon hidden in the box, do they remember information about the identity of those objects or simply that three toys are in the box? Also, I am investigating how many objects infants can remember and if it is harder or easier to remember familiar versus novel objects. Finally, I am investigating young infants’ ability to store information about multiple sets of large numbers of objects in parallel.

I'm currently working on two general lines of research in the lab. The first set of projects looks at the limits of working memory. In one project, I am investigating the role of chunking and sets in defining working memory capacity limits. In another project, I'm investigating the flexibility of these representations and the interaction between working memory and attention. The second line of research is in collaboration with Chad, examining preschoolers' abilities to make logical inferences using information they already know to gain new information.

Toddlers and young children spend much of their time learning from the environment around them. Even without the aid of direct instruction from parents or teachers children are actively learning new words, identifying new people and locations, and forming new conceptual ideas. My research focuses on the logical reasoning strategies children employ in these everyday learning scenarios. Specifically I conduct experiments that examine logical strategies for learning the meanings of novel words and associating novel faces and voices under ambiguous learning conditions.

Junior

I am a junior psychology major, and this is my second year in the lab. I am very happy about being a part of the lab, and am looking forward to learning more about how children develop, and putting my knowledge to use in the future as I go on to teach elementary school.



Mike Yuan
Junior

I am a junior behavioral biology major and this is my first year in the Lab for Child Development. I look forward to learning about infant numerical cognition. I am excited to work and interact with kids, and intend on using the skills and knowledge I develop to pursue a medical career in pediatrics.

Meg Bowen
Sophomore

I am a sophomore psychology and philosophy double major. This is my first year at the lab. I will be working on a brand new study, which is going to be really exciting. I want to work in the field of research psychology, so I am really excited to get some hands on experience!!
