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.
Warm regards,
The CRAM Team
