[Coggroup] CRAM - This Friday - November 1st
by Cognitive Research at McGill 01 Nov '19

01 Nov '19

Dear all, We are happy to announce the next CRAM (Cognitive Research at McGill) session of this term on Friday, November 1st. Dr. Vishnu Murty will be speaking to us about how decision- making engages mesolimbic-hippocampal circuits to stabilize experiences into long-term memory. The talk will span from 12pm-1pm in room 1552 of 2001 McGill College Avenue. Coffee and light snacks will be provided. Please BYOM (bring your own mug). All are welcome! ---- Title: Decision-making engages mesolimbic-hippocampal circuits to stabilize experiences into long-term memory Dr. Vishnu Murty, Temple University ---- Abstract: While a growing body of literature has characterized how individuals use episodic memory to guide decision-making, relatively little is known as to how decision-making influences downstream memory. The ability for individuals to actively make decisions engages regions with the mesolimbic system, which are known to facilitate episodic- memory. In this talk, I will present a series of studies characterizing how decision-making enhances episodic memory for chosen items. Using behavioral and neuroimaging markers, I will provide evidence that engagement of mesolimbic systems during encoding results in the stabilization of memory for decision outcomes over time, consistent with models of systems-level consolidation. Together, these findings support a model by which actively deciding to encode information enhances memory consolidation to preserve episodic memory for outcomes, a process that may be facilitated by re-exposure to the original decision-making context.

[Coggroup] CRAM - THIS THURSDAY October 10th - Dr. Ian Charest
by Cognitive Research at McGill 10 Oct '19

10 Oct '19

Dear all, We are happy to announce the next CRAM (Cognitive Research at McGill) session this term on Thursday (NOT FRIDAY), October 10th. Dr. Ian Charest will be speaking to us about idiosyncratic brain and behavioural representations; title and abstract below. The talk will span from 12pm-1pm in room 735 of 2001 McGill College Avenue. Coffee and light snacks will be provided. Please BYOM (bring your own mug). All are welcome! Title: Idiosyncratic brain and behavioural representations Dr. Ian Charest University of Birmingham -- Abstract: Everyone is unique. Yet, individual differences in brain function and behaviour are too often treated as experimental noise. Given that we experience the world through our own set of idiosyncratic experiences, accounting for individual differences in brain and behaviour is imperative if we are to better understand conscious experience and brain function. In this talk, I will describe a series of large-scale experiments with human participants, investigating perception and conscious access in object recognition, while measuring brain function and behaviour. Using representational similarity analyses (RSA) and Multivariate Pattern Analyses (MVPA), we found that individual differences in brain representations are predictive of individually unique behaviour. This demonstrates the growing need to carefully model individuals in cognitive neuroscience, rather than tacitly assuming commonalities in brain function. To capitalise from these observations, and to develop a better understanding of object recognition in the human brain, we began collecting START, an ambitious large-scale dataset (n>50, ~22h of measurements per participant). This dataset will measure brain activity related to object recognition with multiple imaging modalities (including electroencephalography and functional magnetic resonance imaging), with cognitive tasks ranging from perception, conscious access, working memory, and long term memory. This dataset, shortly after data collection completion, will be made openly available to the community. -- Again, please note that CRAM will be on THURSDAY this week, instead of our usual Fridays, and it will be in room 735. Warm regards, The CRAM Team (Kevin da Silva Castanheira, Anna Mini Jos, & Azara Lalla)

Dear all, We are happy to announce the next CRAM (Cognitive Research at McGill) session this term on Friday, October 4th. Dr. Jordan Axt will be speaking to us about modelling social judgements; title and abstract below. The talk will span from 12pm-1pm in room 1552 of 2001 McGill College Avenue. Coffee and light snacks will be provided BYOM (Bring your own Mug). All are welcome! Title: Using Signal Detection and Drift Diffusion Analyses to Better Understand Discrimination in Social Judgment Dr. Jordan Axt McGill University -- Abstract: Discrimination based on social information can be a subtle but highly consequential phenomenon. In this talk, I will present a measure for assessing discrimination and review studies showing that discrimination can often occur without conscious awareness or intention. We use a signal detection perspective to argue that in many cases, the magnitude of discrimination can be understood as a combination of noise—the number of overall errors made in evaluation—plus bias—the degree to which those errors benefit one group over another. The degree of noise and bias in social judgment differentially respond to various interventions and likely rely on distinct psychological mechanisms. A drift diffusion modeling analysis further shows how discrimination both emerges quickly and exacerbates during judgment, and how novel interventions can separately alter these two processes.
