Chaz Firestone (personal homepage)
Assistant Professor of Psychological and Brain Sciences
Chaz is interested in the nature of seeing, thinking, and the relation between the two. He came to Hopkins after completing his graduate work in the Department of Psychology at Yale; before that, he spent some time as a graduate student in philosophy at Brown, where he was also an undergraduate. When he's not trying to figure out how seeing and thinking relate to one another, Chaz likes to grapple, eat ceviche, and set spurious world records for fastest circumnavigation of the globe on foot.
Graduate Student (co-advised by Jonathan Flombaum)
Chenxiao is interested in connections between what we see and what we can create, including how we perceive objects that we can use (e.g., graspable tools) and objects that can interact with each other to make something new (e.g., jigsaw puzzle pieces). She comes to us from the University of Rochester, where she studied affordances in the CAOs Lab with Brad Mahon, and took advanced math courses for fun. Chenxiao is also a skilled ATV pilot, and is rumored to be in a band.
Zekun is exploring the perception of complexity — how and why some objects look informationally dense, and others look informationally sparse. Her previous work at the Chinese Academy of Sciences explored visual attention to painful images (such as a hammer hitting a hand), including one study in which she inflicted actual pain on her subjects by attaching a contact-heat thermode to their arms. For this reason, we don't mess with Zekun.
Graduate Student in Philosophy
Cara is interested in how perception interacts with language and skill acquisition, and how development and learning together explain our cognitive abilities. She studied (and made) art before completing a graduate diploma at the University of Melbourne in both philosophy and psychology. Cara spends her leisure time reinforcing the stereotype that philosophers have their ‘heads in the clouds’, as an amateur photographer of the night sky (here of the 2012 transit of Venus).
Graduate Student in the Halberda lab
Qian studies how we remember what we see, and how remembering is or isn't like seeing. While working as a translator of popular books (incl. Steve Jobs by Walter Isaacson!), she read some psychology books and became fascinated by how the mind works. So, she joined Ying-Yi Hong's Culture Lab at the Chinese University of Hong Kong, and explored the Uncanny Valley phenomenon. Qian gives you two lab members for the price of one, since she is rarely seen without her cat, Pipi.
Jose claims to be interested in interactions between language and perception, but his latest project is about beer, so who knows. He approached Chaz after a talk with a fantastic resume and even better questions, so Chaz responded by offering him a job. Jose's previous work in Mariko Moher's Early Childhood Cognition Lab at Williams College explored how the mind prioritizes different features (e.g. color vs. shape) in sorting objects; now Jose sorts things here in the lab.
Pat is a junior studying applied math and cognitive science. In the lab, he's exploring how very tiny fluctuations in behavioral responses can answer very big questions about how perception works. Pat has an unusual talent for listening: He is a member of the peer listening group A Place To Talk, and he subscribes to more podcasts than Chaz has heard of. He also likes watching gourmet cooking shows, and then applying this knowledge to his other pastime: microwaving burritos.
J.J. is a senior at JHU studying cognitive science and philosophy. Here in the lab, he is excited to conduct a project on physical reasoning for which he won a Provost's Research Award — technically earning the lab its first ever 'grant'! J.J. is also involved in the PILOT program, as well as the Prometheus Undergraduate Philosophy Journal. When not on campus, he enjoys exploring Baltimore with his "posse" (J.J.'s word), or spending a quieter night in with an online lecture.
Our lab approaches this and other questions using the tools of vision science. Much of our work uses computer-based psychophysical experimentation, but we also explore these questions using larger real-world environments, computational models, 3D-printed stimuli, studies of brain-damaged patients, and even some unusual 'field work' (including experiments run in New York City's Times Square!).
A central research interest in the lab is how perception is 'smarter' and richer than we often give it credit for, often influencing or even incorporating surprisingly sophisticated processing that you might typically associate with higher-level cognition. For example, we've recently become interested in how our minds generate physical intuitions about the world (e.g., how we determine that a pile of rocks will topple over or stay upright). In one recent project, we have explored how basic representations of an object's shape can reach all the way up to our higher-level judgments about how that object will behave in physically rich scenarios, creating illusions of balance whereby objects that look hopelessly unstable may in fact balance perfectly (or vice versa).
We have also engaged with core questions about the underlying 'format' of what we see. Just as the format of a digital file constrains how it can be used (consider how a .doc file is useful for different purposes than a .pdf), the way our minds encode and represent information constrains how that information can be used by other processes. We have explored the format of perceptual representations by taking objects and shapes as a case study. Using new paradigms the lab has developed, we have found surprisingly direct evidence that the mind represents objects much as an architect might represent a building in the format of a 'blueprint' or 'skeleton' that explains why objects look and behave as they do.
The lab also has a deep interest in foundational questions about the nature of perception. In particular, we have explored the ways in which higher-level factors such as language, desire, emotion, and action can and cannot influence what we see. Our work on this long-standing question in cognitive science has suggested that vision is not simply another kind of cognition, but rather is a truly distinct, 'encapsulated' process in the mind.
