[CaBSSem] [Psychat] Cognition & Brain Sciences Seminar 3 pm on Friday 8th March

Thu Mar 28 12:07:14 PDT 2024

A reminder that tomorrow. Friday 29th is Good Friday, and the university is closed, so there will be no seminar.

On April 5th, I will be hosting our last seminar of great interest, featuring Todd Woodward.

The reason this seminar is a suitable end to the series is that Todd was my first graduate student at UVic, and has gone on to a stellar career.

The second reason is the nature of the talk, dealing with fundamental aspects of the signal in fMRI research.

Todd's professional trajectory can be found here:

I am providing advance notice of the talk because I think you definitely will want to arrange your schedule to attend:

Title: Brain networks detectable by fMRI: A Focus on Tasks

Abstract: Functional Magnetic Resonance Imaging (fMRI) provides information about the flow of
blood-oxygen-level-dependent (BOLD) signal in the brain. BOLD signal flow forms into
reliable configurations, referred to as macro-scale BOLD brain networks. fMRI data can be
collected either with or without the timing of defined events taking place during scanning
being known and recorded. If such timing information is available, it can be used to constrain
the BOLD signal variance exclusively to that which is predictable from this timing
information. When timing information from cognitive tasks is used, this constrained variance
can be submitted to a dimensional analysis which produces macro-scale BOLD brain
networks which span many tasks, and their response to a wide range of task conditions can be
studied to determine the cognitive functions which elicit the specific configurations. For
example, in the relevant brain networks, the difference between long and short maintenance
periods in working memory should be visible in the duration of the BOLD response, as should
the duration of hallucination events. Examples of cognitive functions which elicit specific
configurations are Access to Internally Stored Information and Re-evaluation of a Response.
Symptoms of schizophrenia are related to the hypo- or hyper-activation of specific networks
under specific task conditions. This application of fMRI could be used for pre-surgical
planning, or as targets for neuromodulation, depending on the degree to which these BOLD
signal configurations match neural configurations and are reliably retrievable on the level of a
single-subject.

Title: Patterns of Long-term change in Implicit and Explicit Attitudes and Stereotypes

Abstract: The past few years have been a tumultuous period of change and transformation – from elections to social movements to global pandemics and conflict. Over this time, scholars and society have inevitably wondered: how are our minds changing? Are the attitudes (preferences) and stereotypes (beliefs) that we hold about groups (e.g., gender, race, sexuality) changing in recent years? And how does this recent change compare to the longer shadow of historical attitudes? In this two-part talk, I will first present evidence from large-scale social surveys on contemporary changes in implicit and explicit social group attitudes and stereotypes since 2007. In the second part, I will situate these changes within the longer span of 200 years of historical text and the representations of groups since 1800. Together, the work sheds new light on the possibility (and limits) of long-term change in our attitudes and stereotypes of social groups.

Please note that the seminar will be held via Zoom.

On the Dynamics of Action Representations Evoked by Names of Manipulable Objects

Daniel Bub and Mike Masson

Two classes of hand action representations are shown to be activated by listening to the name of a manipulable object (e.g., cellphone). The functional action associated with the proper use of an object is evoked soon after the onset of its name, as indicated by primed execution of that action. Priming is sustained throughout the duration of the word’s enunciation. Volumetric actions (those used to simply lift an object) show a negative priming effect at the onset of a word, followed by a short-lived positive priming effect. This time-course pattern is explained by a dual-process mechanism involving frontal and parietal lobes for resolving conflict between candidate motor responses. Both types of action represen- tations are proposed to be part of the conceptual knowledge recruited when the name of a manipulable object is encountered, although functional actions play a more central role in the representation of lexical concepts.

This Friday's CABS seminar will feature Alan Kingstone from UBC

https://psych.ubc.ca/profile/alan-kingstone/

<https://psych.ubc.ca/profile/alan-kingstone/> From  Alan's website:

Dr. Alan Kingstone is the director of the Brain, Attention and Reality Lab at UBC. He has pioneered methods and approaches to the study of attention and cognitive ethology, such that his research strongly connects with people as they interact in the world around them. The lab’s multidisciplinary research program includes work with children, patients, and healthy adults using a variety of techniques (e.g. natural observation, eye tracking, brain imaging, body motion tracking), all aimed at answering questions ranging from basic aspects of visual attention to more complex aspects of social cognition. He is a Fellow of the Royal Society of Canada and the Association for Psychological Science.

The seminar will be held in person in the Reading Room beginning at 3 pm.

 Exploring the interplay between mind perception and attention in controlled environments and complex realities

Alan Kingstone, University of British Columbia

We effortlessly categorize people as possessing minds. Yet, the extent to which we attribute minds to individuals can vary, with real people perceived to have more mind than depictions of them, such as photographs. I examine how different shades of mind affect human behavior and attention. By employing diverse research methodologies, including naturalistic observation, mobile eye tracking, and surreptitious behavior monitoring, I also reveal a fundamental interplay between overt attention (where one looks) and covert attention (attending to someone out of the corner of one's eye).
