The Discovery of Processing Stages: Extension of Sternberg's Method. Anderson, J.R., Zhang, Q., Borst, J.P.,& Walsh, M.M.Mapping Working Memory Retrieval in Space and in Time: A Combined Electroencephalography and Electrocorticography Approach. Zhang, Q., van Vugt, M., Borst, J.P., & Anderson, J.R.The Impact of Inserting an Additional Mental Process. Zhang, Q., Walsh, M.M., & Anderson, J.R.Neural imaging techniques (EEG, MEG, ECoG). I develop machine learning methods that allow us to track when and where these hidden cognitive process occurs in the brain, using a combination of Visual processing, memory retrieval, decision making are hidden cognitive processes that are not directly observable from behavioral responses. Ongoing project*: How does prior knowledge influence the temporal dynamics and recall performance during memory search?.Semantic knowledge influences whether novel episodic associations are represented symmetrically or asymmetrically. Popov, V., Zhang, Q., Koch, G.E., Calloway, R.C., & Coutanche, M.N.Proceedings of the 40th Annual Conference of the Cognitive Science Society. Fast Memory Integration Facilitated by Schema Consistency. Zhang, Q.*, Popov, V.* (co-first-authors), Koch, G.E., Calloway, R.C., & Coutanche, M.N.I study how our prior knowledge serves as a scaffold where new memories bind to,Īnd how this scaffold can faciliate more efficient search over memories. How we learn new information is constantly shaped by our prior knowledge. The influence of prior knowledge on learning and memory Ongoing project*: When do people terminate their search in memory, and what are the factors to enable them continue recalling?.Ongoing project*: Why are mnenomic techniques such as the method of loci effective in faciliating memory recall?.Once we understand what gives optimal or rational solutions, we can design methods to further improve memory recalls.

Ongoing project*: Do people rationally select between alternative memory cues to maximize their memory recall?.The When Where and Why of Human Memory Retrieval. Proceedings of the 43th Annual Conference of the Cognitive Science Society. A rational account of anchor effects in hindsight bias. Wilson S., Arora S., Zhang, Q., & Griffiths, T.L.The dynamics of exemplar and prototype representations depend on environmental statistics. Devraj A., Zhang, Q., & Griffiths, T.L.Zhang, Q., Griffiths, T.L., & Norman, K.I analyze these aspects of human memory system by comparing human behavior to optimal or rational solutions to such computational problems.
