Lisa Feigenson, Ph.D. feigenson@jhu.edu http://www.psy.jhu.edu/~feigenson/ 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.

Justin Halberda, Ph.D. 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. |

Rebecca Rosenberg, Ph.D. 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. |

Rachel Austin 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 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. |
