Caitlin Tozios (caitlin.tozios[at]

Hi there, I’m Caitlin, and I am K’s Ph.D. student in the lab. I completed my BSc here at the University of Toronto, majoring in psychology and neuroscience, and I finished my MSc at Wilfrid Laurier University. My thesis, An Examination of Imagined Contexts: The Unreliability of Context-Dependent Memory Effects in Recall was supervised by Dr. W. Hockley, and we studied whether the effects of worse memory recall for words after changing physical contexts could be mitigated by reinstating imagined contexts at retrieval.

My current research interests lie in improving memory retrieval through methods directly applied at the retrieval stage or during encoding processes. Studying the reasons why some strategies may work better than others, or why some may fail or are ineffective, will inform us and enrich our mnemonic environment. I am also interested in metamemory and aging. That is, how do older adults perceive their own memory abilities and judgments and how do they use this to inform memory decisions?

Outside of school, I love to take naps (usually with my son (cat) named Beaty) because I was born a sleepy baby and can never get enough. I miss the days when my metabolism was better and I could eat more junk, but I still love rice and noodles and fried chicken; and in the never-ending quest to be seemingly relevant – exploring new restaurants all over the place. You can usually find me in the lab at UTM, downtown for classes, or in IKEA.

How do we perceive, select, process, retain, and retrieve visual information? How might we improve our working capacity with this information? I’m Ben and my current goal is to (learn to) exercise computer-assisted behavioral, EEG, and fMRI measures to confront these long-standing questions! My current projects (2019) aim to decipher how our Visual Working Memory (VWM) system can update its representations across time. Future prospects include real-time EEG and behavioral analysis, attentional selection and suppression, transfer of information involving VWM and/or Long-Term Memory, brain-computer-interface design, and data visualization. Especially during exam season, I enjoy driving/racing cars, playing/making music, gaming, anime, programming, tennis, or Korean food. Feel free to follow me on Insta for updates on research and hobbies: ‘benfpv’!

Project (s) this lab member is running: Irrelevant Feedback, Stimulus-Response Mapping, Continuous Performance!

April Pereira

I think that one of the most interesting things we can do is delve into everyday phenomenon right in front of our eyes that still feel so unknown. In this lab, I’ve been inquiring into these occurrences through both behavioral and neurophysiological means.

At the moment, I’m exploring (1) the effect of irrelevant feedback on visual long-term memory, (2) the effect that honest/dishonest feedback can have on preference for what’s giving you feedback and if that preference bleeds into ones that are even just similar to what’s giving you feedback, and (3) how continuous performance can be broken down and evaluated (do we accumulate information, in the same way, to be confident about an answer for tasks that have different demands?) I’m usually in the lab eating salt and vinegar chips as I explore.

Undergraduate Project Leaders

Project (s) this lab member is running: Countermanding, Stimulus-Response Mapping!

Fatima Wasif

I’m Fatima, a fourth-year student, specializing in Psychology and majoring in Biology for Health Science. I’m particularly interested in using electrophysiological methods like EEGs to record brain activity during cognitive tasks to understand how electrical action correlates to and changes as intellectual decisions are made.

To this end, I currently run EEG projects involving the examination of an individual’s ability to countermand their actions in response to variable cue information, as well as tasks involving Stimulus Response Mapping to study how participant liking towards objects changes as a consequence of experiencing betrayal via feedback given by the object.

For fun, I like eating copious amounts of black salt seasoned oranges,  reading – much less than I would like, and bankrupting myself buying pot plants and budget earrings.

Project (s) this lab member is running: Continous Performance!

Jeanny Kim

Hi! My name is Jeanny Kim and I’m in the fourth year double majoring in psychology and political science.

I got involved in research in Fukuda lab because I took a course in Human Memory and I was fascinated with it. Currently, I’m helping out with CP 3.5 and starting my IRP this year about evidence accumulation in the brain and how perceptual decisions are oriented toward it.

Something interesting about me is that I love Korean food (partly because I was born in South Korea) and I would like to travel around the world on a makeshift van.

Project (s) this lab member is running: VWM Purging!

Saphia Shariff

HELLLO! My name is Saphia and I am a fourth-year student specializing in psychology at the University of Toronto.  I am currently interested in discovering why the amount of information in Visual Working Memory (VWM) decreases every time it is inquired? (even when we are informed of multiple inquiries in advanced). To answer this question, I have been running a series of change detection tasks to simply determine “Why do we lose information in memory?”. Working in the Fukuda lab has been an amazing journey for the last two years as it opened my eyes to the importance of cognitive psychology and the significant role it plays in our simple day to day lives. For fun, I love eating, sleeping, watching T.V (I promise I am not lazy) and traveling!

Project (s) this lab member is running: Countermanding!

Amanda Leonetti

My name is Amanda, I am a fourth-year undergraduate student majoring in Biology for Health Sciences and Psychology. I am interested in analyzing brain activity and behavior to explore relationships existing between memory and anxiety. I am particularly interested in (1) how varying levels of trait anxiety affect one’s ability to countermand their actions in response to various cues and (2) analyzing the fear pathway involved in the “Fight or Flight Response” in healthy participants, in order to understand the dysfunction that occurs in this pathway in individuals diagnosed with General Anxiety Disorder. Currently, I am running experiments examining brain activity and behavior in order to tease apart proactive vs reactive fear individuals in the countermanding task, as well as examining any correlating levels of trait anxiety using the STAI test results. When I am not studying anxiety, I am usually teaching dance or in the gym!

Project (s) this lab member is running: Meta-memory!

Kyana Profile Picture
Kyana Chhouk-Fletcher

Hey! I’m Kyana, an undergrad at U of T and a project leader in the Fukuda Lab. I love to know everything I can about humans so I major in psychology, and minor in biology and anthropology. My study focus in the lab is metacognition of visual working memory. I hope to find the key to improving our ability to recall information by altering the cognitive processes associated with encoding. I also have a great interest in abnormal psychology and the cognitive processes involved in visual memories associated with a multitude of psychological disorders.

However, when I’m not studying people you can find me baking or cooking up something in my kitchen!
