The Research Team


Dr GundersonDr. Elizabeth Gunderson

Elizabeth Gunderson, Ph.D., is an Assistant Professor in the Department of Psychology at Temple University. She received her Ph.D. in Developmental Psychology from the University of Chicago in 2012 and her B.A. in Computer Science & Psychology from Yale University in 2005. Dr. Gunderson’s research focuses on the cognitive and socio-emotional factors that affect young children’s academic achievement, especially in the domain of mathematics.

Postdoctoral Scholar

Nicole Hallinen

Nicole is an IES Postdoctoral Fellow in the Department of Psychology and College of Education at Temple University.  She received her Ph.D. from Stanford’s Learning Sciences & Technology Design program in 2015 and a BS in Psychology and a BA in French & Francophone Studies from Carnegie Mellon University in 2009.  Dr. Hallinen’s research investigates how the design of instructional materials affects students’ learning and transfer of mathematical ideas, primarily in algebra and physics.

Graduate Student

Cathy (Kexin) Ren

Cathy is a doctoral student in Psychology at Temple University, concentrating in Developmental Psychology. She received her B.S. in Psychology at Sun Yat-sen University in China. She is interested in children’s numerical learning, especially difficulties they have in learning rational numbers. By doing research in this field, she hopes to find a way to help both children and teachers to better learn and teach mathematics.

Lab Managers

Vicki Bartek

Vicki received her B.A. in Psychology in 2015, from The College of New Jersey, and her M.S. in Experimental Psychology in 2017, from Seton Hall University. In her previous work she studied errors in memory recall with Dr. Marianne Lloyd, and the event related potentials correlated with recall and familiarity with Dr. Andrew Leynes. She hopes to examine the role of parent and child interactions and parental control in children’s cognitive and emotional performance.



Jorge Carvalho Pereira

Jorge received his B.A. in Psychology in 2015 from the University of Delaware and he then attended the M.A. in Psychology program at Rutgers University – Camden. His research focuses on the coalescence of nature and influence of early experiences in the long-term development of children and their abilities. In particular, Jorge’s current focus is centered on further understanding the contributions of early parent-child interactions for children’s later development along cognitive domains such as mathematical reasoning.



Yiqiao Wang

Yiqiao received her B.S. in Developmental Psychology, from the University of California, San Diego, in 2018.  In her previous work, she studied the early development of children’s numerical understanding and its relation to natural language with Dr. David Barner.  Her current research interests include young children’s numerical learning and factors that contribute to individual differences in the math skills of young children.

Postdoctoral Scholar

Nicole Sorhagen

Nicole received her Ph.D. from Temple University in August 2014 and proceeded to gain employment in a post-doctorate position at the University of Pennsylvania where she continued her work in the lab in order to further her personal research. Nicole is currently a professor at Millersville University.  Nicole’s research interests lay in understanding how social processes influence cognitive development. The well-established achievement gaps in America between income, ethnicity, and gender has led Nicole to a secondary research interest focused on inequalities in achievement.
