Among other things, we're interested in the limits of visual attention and visual working memory, the psychophysics of numerical estimation, and the interfaces between vision and language. We maintain strong collaborative ties with the Laboratory for Child Development and the Visual Thinking Lab, as well as the larger Vision Sciences Group at JHU.
Dr. Justin Halberda directs the Vision and Cognition lab, and co-directs the Laboratory for Child Development with Dr. Lisa Figenson. He currently holds appointments in the Department of Psychological and Brain Sciences (primary) as well as the Department of Cognitive Science. His recent work in this lab is focused on the organization of visual attention and working memory, psychophysical modeling of the human approximate number system, and the semantics of logical vocabulary (e.g., quantifiers).Curriculum Vitae
Josh graduated from Johns Hopkins in 2015 with undergraduate degrees in Cognitive Science and Philosophy. Before working in the VCL, Josh spent a year in Madrid, Spain teaching English to high school students as part of a Fulbright grant. His interests include philosophy of mind, computational models, and cognitive development.
Tyler graduated from Johns Hopkins in 2015 with a B.A. in Cognitive Science and served as the Lab Manager for three years. Currently he's pursuing his doctorate in Linguistics at University of Maryland, College Park and is interested in Psycholinguistics, Semantics, and Language Acquisition.
Hrag defended his dissertation, "Costs of Manipulating Information in Visual Working Memory" in July 2015. In it, he focused on the following questions: is the limit for manipulating information independent of that for storing information and are original representations updated or do they remain separate once they have been subjected to a given computation? To this end, he has developed a novel method - the Flicker paradigm - which allows for storage constraints to be studied within the context of how VWM is flexibly used in the real world. He is currently a Postdoctoral fellow under George Alvarez in Harvard's Vision Sciences Laboratory.
