JiangLab Research
Research in our laboratory focuses on how cognition constrains perception and action. We are interested in how humans perceive, attend, learn, and remember visual work. Our work, situated at the border between perception and higher-level cognition, is revealing how cognitive factors, such as attention and working memory, constrain visual perception.
Representative publications
*This study challenges the widely accepted idea that
attention is limited by the number of foci.
*This study challenges the idea that visual working
memory is a robust form of memory representation. It provides evidence for two
modes of working memory that differ in their fragility to subsequent
interference.
*This study reveals that the posterior parietal cortex is
sensitive both to the complexity of memory objects and to the number of
objects, providing evidence for both the flexible-slot and fixed-slot models of
visual working memory.
*This study shows that implicit learning of repeated
visual context occurs even in the absence of attention, but the manifestation
of learning depends on attention.
*This study shows that objects held in visual working
memory are represented in spatial relation to one another. It reveals a
property of working memory – its topographic representation – that
is often neglected in discussions about memory capacity.
*This study reports the phenomenon of contextual cueing,
a form of implicit learning in vision.
