Our Lab

The Different Minds Lab is a research group organized by Dr. Jim Tanaka, a cognitive psychologist and Professor in the Department of Psychology at the University of Victoria.

The scientific mission of the lab is to understand the cognitive processes and temporal dynamics of expert face and object recognition. In normal adults, everyday experience leads to an “expertise” for faces that enables us to recognize a familiar face or emotional expression in a split second without conscious thought. In some individuals, such as birdwatchers and dermatologists, extensive experience in a specialized interest also leads to expert recognition for these objects-of-expertise. Understanding the nature of holistic processing, a cognitive mechanism that is fundamental to face perception and memory, and the visual learning mechanisms that operate along the “path to expertise” is central to our research goals.

In the past few years, we have worked to transform our lab to primarily conduct web-based experimentation. Beyond learning existing tools, we have focused on developing new methods to push the boundaries of this field. Our main project has been Gazer- an extension of jsPsych that allows us to collect eye-tracking data using the video feeds from participant’s laptops.

As of 2023, we have shifted our primary focus in the lab to a new data modelling software, PsiZ, created by Dr. Brett Roads. So far, we have examined how PsiZ can track the development of perceptual expertise. PsiZ renders powerful visualizations that depict our participants’ perceived categorical structure of stimulus set items. Using PsiZ, we often survey experts and novices in various visually-based domains (e.g., warblers, rocks, NBA basketball, and Other-Race faces) to examine how one’s perception shifts with varying levels of expertise. We are also currently testing the limits of PsiZ by exploring how it may be used to assess individual differences in visual perception.

Members of the Different Minds Lab frequently collaborate with researchers from other institutions and labs. To support cross-lab collaborations, Dr. Jim Tanaka founded the Different Minds Collaborative (DMC), an interdisciplinary research collaborative that meets monthly to discuss ongoing research in vision sciences. These monthly discussions frequently spark cross-lab collaborations that have, in turn, fostered a strong sense of community within the DMC.

DML Attends VSS 2022!

May 13-19, 2022. The Different Minds Lab was finally able to make its way back to Vision Science Society in St. Pete’s Beach, Florida! Alison, Jim, and Amy each presented posters of their most recent work. Jim and Amy were also able to make a splash on Monday’s Demo Night with a gaze-contingent paradigm of the new Gazer program.

Check out Alison’s poster, Jim’s poster, and Amy’s poster.

At virtual OPAM 2021, Amy will present a poster titled “Investigating the time course of exogenous attention using a web-based eye-tracking tool”.  The poster describes the details of her new tool Gazer,  which will allow vision scientists to conduct eye-tracking using laptop cameras. 

Alison Campbell wins President’s Fellowship for Research-Enriched Teaching

June 1, 2021. Alison has won the President’s Research-Enriched Teaching Fellowship for her proposed reinvention of the upper-level undergraduate class on cognitive psychology. This award helps PhD students and postdoctoral fellows to embrace new teaching and mentoring opportunities and provide more research-based learning experiences for undergraduate students.

Alison Campbell presents talk at OPAM 2020

November 19, 2020  At Virtual OPAM 2020, Alison will present a series of experiments we conducted to test whether visual masks can be manipulated to disrupt face identity processing at different levels of the visual hierarchy. OPAM 28 will be held online on November 28-29 and registration is free! 

Campbell, A. & Tanaka, J. W. Conscious visual perception of face identity requires at least 33 ms of uninterrupted low-level processing and 100 ms of uninterrupted high-level processing. Talk Session 4, Thursday November 19, 2:45 pm CST for live talk and Q & A session.
