Research Interests: I am interested in many aspects of human cognition (see blurbs below!), but recurring themes include the role of the frontal lobes in the regulation of thought, and the link between perceptual and memory systems.
Research in progress: One major theme in the lab right now is an effort to understand the costs, as well as the benefits, of frontally-mediated cognitive control. Our current ideas about this are summarized in Chrysikou et al., 2014, Neuropsychologia. A second major theme concerns how conceptual information is dynamically retrieved and reconfigured; this work includes studies of how visual features are integrated into concepts (e.g., Coutanche & Thompson-Schill, Cerebral Cortex), how new conceptual information is integrated with prior knowledge (e.g., Coutanche & Thompson-Schill, JEP:General), and how different variables affect how we retrieve conceptual information (e.g., Hsu et al., J of Cog Neuro).
Research Interests: I examine how semantic memory structure enables and constrains high level cognitive processes, such as memory retrieval and creative thinking, in typical and clinical populations (such as persons with autism). To achieve this, I use computational methods to represent semantic memory structure and empirical neurocognitive methods to directly examine these computational findings.
Research Interests: I’m interested in the how episodic memories are altered with consolidation, and how this process is related to the acquisition of semantic and conceptual knowledge. As a graduate student, I used behavioral and neuroimaging methods to examine how episodic memories with overlapping information come to be represented over time.
Research Interests: I am interested in the role of executive function in accessing, maintaining and manipulating semantic memories in the processing of both verbal and non-verbal input streams. For example, predictive processing may play a role in our ability to understand rapid linguistic input. Prediction may also contribute to our ability to rapidly identify objects and recall relevant information about them as we move through the visual world. However, open questions remain regarding the extent to which predictive processing in the verbal and non-verbal domains relies on shared neural and cognitive mechanisms, and the extent to which differences across domains can be explained by general principles of neural organization. Similar questions arise in comparing working memory function and the broader class of contextual facilitation effects across the verbal and non-verbal domains.
Research Interests: I study how and by what properties the brain leverages visual information in behaviors such as recognizing and categorizing objects and perceiving scenes. Using behavioral and neuroimaging methods with computational modeling, I aim to elucidate how certain ‘specialized’ layers of large-scale neural networks interact to give rise to visual perception and memory-related processes.
Research Interests: I have a broad interest in long-term memory.
