Dr. Andy Yonelinas

Professor, Human Memory Lab Director

Ph.D. in Experimental Psychology from McMaster University, Canada, 1995

B.S. in Cognitive Science from University of Toronto, Canada, 1990

Email : apyonelinas@ucdavis.edu

Research Interests

Dr. Yonelinas is examining the processes underlying human memory. In order to characterize the functional nature of different memory processes, he is currently using implicit and explicit tests as well as several ‘second generation’ procedures such as the process dissociation procedure, the independence remember/know procedure, and ROC modeling procedure. In order to determine the neural substrates of memory encoding and retrieval processes he is i) examining memory impaired patients such as amnesics and Alzheimer’s patients, and ii) examining the physiological correlates of memory processes using neuroimaging techniques such as event related potentials and function magnetic resonance imaging. The goal of this work is to develop and test models of memory that address recent behavioral, neuropsychological and brain imaging data.

Email : aaborders@ucdavis.edu

Research Interests

Alyssa is a graduate student in the Perception, Cognition, & Cognitive Neuroscience (PCCN) area of psychology. She earned her B.S. in Neuroscience from the University of Michigan in 2009 and then worked as the lab manager for the HML before starting grad school. Using both neuroimaging and neuropsychological methods, the goal of her research is to understand the contributions of the hippocampus to precision and complex representations in both long-term memory and visual working memory.When not working, Alyssa spends most of her free time outdoors. She enjoys hiking to swimming holes, climbing trees and rocks, biking to breweries and food trucks, and napping anywhere a hammock can be strung up.


 Kathryn Bousquet

Graduate Student

B.A. in Psychology with linguistics minor from Saint Michael’s College, 2010

Google Scholar

Email : kgbousquet@ucdavis.edu

Research Interests

Kathryn is a Psychology graduate student at UC Davis, where she works in both the Human Memory Lab, as well as the Cognitive Neuroscience of Language lab with Dr. Swaab. Her unique appointment in both labs allows her to study the interactions of sentence processing and memory. Her research is focused on the various sources of information that are used to generate expectations about how a sentence will unfold. She also examines how these expectations influence online sentence processing, as well as the construction of sentence representations in memory. In her free time, Kathryn enjoys reading, cross stitching, playing piano, and getting outside.


 Robin Goodrich

Graduate Student

B.A. in Psychology from San Francisco State University, 2011

Google Scholar

Email : rigoodrich@ucdavis.edu

Research Interests

Robin is a Ph.D. candidate in the Perception, Cognition, & Cognitive Neuroscience (PCCN) area of psychology. Using behavioral, neuropsychological, and eye-tracking methods, her work is situated at the intersection of perception, visual working memory, and long-term memory. Robin is particularly interested in how the different processes underlying these traditionally separate research domains are related, and especially how they may be supported by overlapping brain regions. Additionally, Robin studies the role of the hippocampus in precise vs. complex visual working memory representations, and the trade-off in performance for these different representational requirements. Aside from research, Robin is a zealous Harry Potter fan and while (still) waiting for her Hogwarts letter, she enjoys binge-watching Netflix, cooking, any and all dogs, and happy hours with her lab family.


Dr. Andrew McCullough

Google Scholar

Email : amccullough@ucdavis.edu

Research Interests

Andrew is a Ph.D. candidate in psychology, interested in wide-ranging topics in cognitive psychology, primarily under the umbrella of learning, memory, and perception.  Andrew’s dissertation work aims to understand the effects of acute stress on processes involved in long-term memory.  He is also interested in applying research-based principles of learning and memory to improve educational efficacy, in and out of the classroom setting.  Andrew received his B.A. in psychology from the University of North Carolina Wilmington in 2005, and his M.A. in cognitive psychology from UNCW in 2010.  When not conducting research or teaching, Andrew is likely enjoying the outdoors in the company of his dog.


Ilse Pastor

Jr. Research Specialist

B.S. in Cognitive Neuroscience and Professional Writing from University of California, Davis, 2018

Google Scholar

Email : impastor@ucdavis.edu

Research Interests

Ilse is the current Jr. Research Specialist for the Human Memory Lab, where she handles both administrative and research tasks that range from training and scheduling Undergraduate Research Assistants, to developing experimental tasks using programming languages such as Python. Her research interests span a wide variety of topics, including visual perception, attention, prospective memory, and the impact of technology on daily cognitive functions. Particularly, Ilse is interested in how intrusive media and technology use may interrupt our ability to pay focused attention, impact academic performance and memory for past and future events. For this purpose, Ilse spent the last two years of her undergraduate career conducting independent research investigating how providing students with technology breaks during class helps their academic performance. Outside of lab, Ilse likes to spend time with her daughter, husband and cat, wake up bright and early to exercise in nature, play the piano anytime there is a chance, and catch up with family and friends.

Personal Research

Current literature suggests that mindfulness practices may have both positive and negative impacts on memory; they have been shown to increase working memory capacity, but also appear to make one more susceptible to false memories. Aditi is currently working on an honors projects, where she is exploring the interplay between mindfulness and the above-mentioned cognitive processes. Her research has practical implications for those who practice mindfulness, or those who want to become more familiar with the practice. The results of this study may also inform us as to better practices to help increase working memory in individuals who suffer from memory deficits.

Neurobiology, Physiology, and Behavior; Psychology minor, 2017
Email : njaha@ucdavis.edu
Personal Research

We extract and learn patterns in the world via statistical learning. Much research has focused on establishing that we can learn statistical regularities through various modalities—auditory, visual, and tactile; however, there has been little research to see how memory for the acquired sequences is retained for days after the initial learning. Niti is currently working on an individual research project that investigates whether there are differences in long term memory for sequences of sounds and shapes.
