SUMMARY:Department Speaker Series: Carolyn Parkinson (UCLA\, Psychology)
DESCRIPTION:Title: The brain in the social world: Integrating approaches from psychology\, neuroscience\, and social network analysis\n \nAbstract: This talk will cover work integrating theory and methods from psychology\, neuroscience\, and social network analysis to examine how people track\, encode\, and are influenced by the social networks that they inhabit. One set of studies tests if\, when\, and how people retrieve knowledge of familiar others’ positions in their real-world social networks when encountering them. Related research tests how this knowledge\, once retrieved\, shapes downstream processing and behavior. A second set of studies tests if human social networks exhibit assortativity in how their members perceive\, interpret\, and respond to their environment. Consistent with this possibility\, we find that proximity between people within their social networks is linked to similar neural responses to naturalistic stimuli\, similar subjective construals of such stimuli\, and similar patterns of brain connectivity. A final set of studies examines how shared understanding relates to overall levels of social connectedness within communities. We find that people who process the world in a manner that is more reflective of community norms have greater overall levels of subjective and objective social connection. All human cognition is embedded within social networks\, but research on information processing within individuals has progressed largely separately from research on the social networks in which individuals are embedded. The set of findings to be reviewed in this talk suggests that integrating approaches from psychology\, neuroscience\, and social network analysis can provide new insights into how individuals perceive\, shape\, and are shaped by the structure of their social world.

SUMMARY:Department Speaker Series: Scott Page (University of Michigan\, Business\, Political Science\, Complex Systems\, and Economics)
DESCRIPTION:Speaker: Scott E. Page (University of Michigan\, Santa Fe Institute). (website) \nTitle: Organizations and Cultural Coherence \nAbstract: I construct a mathematical framework to elucidate and analyze the interdependence between structural features of an organization and some of its cultural attributes.  By the structure of an organization\, I mean whether individual actions are assigned hierarchically\, agreed upon through a more equal democratic process\, or encouraged through incentives.  By culture\, I will focus on standard measurable features such as tightness\, individualism\, trust\, risk taking\, and uncertainty avoidance.  I show that congruence – the alignment of organization structure and culture – though an often articulated organizational goal does not\, except in rare cases\, imply efficiency.   The creation of a healthy\, constructive culture and not congruence should therefore be the goal of organizations. \n

SUMMARY:Department Speaker Series: Swabha Swayamdipta (USC\, Computer Science)
DESCRIPTION:Title: Understanding Online Discourse through Social Context and Structured Pragmatics \nAbstract: In an increasingly online world\, understanding discourse on social media is akin to understanding our society. However\, when it comes to social media discourse\, a disproportionate amount of focus has been laid on content moderation via hate speech detection. In this talk\, I will address a key limitation of this application: existing hate speech detection systems are riddled with racial biases introduced during annotation\, which are reinforced and propagated by models trained on such data. I will present the inadequacies of current methods for debiasing hate speech detection and show how the subjectivity of this task design leads to debiasing failures. Next\, I will focus on uncovering the origin of bias in toxic language detection. I will demonstrate how annotators’ demographics and beliefs influence their toxicity ratings\, and how ignoring such societal context can lead to biased outcomes. Finally\, I will present some ongoing work on understanding online discourse on homelessness\, which presents some unique challenges. Overall\, I will argue for the value of rethinking traditional the hate speech classification task\, and the need for richer context and nuance when considering online discourse.

SUMMARY:Department Speaker Series: Jimmy Calanchini (UCR\, Psych)
DESCRIPTION:Title: Putting the Environment Back in Person-Environment Fit\n \nAbstract: Psychology scientists have recognized for decades that individual behavior is a function of both the person and the environment. However\, due to a dominant focus on individual differences\, psychological data on intergroup bias have historically been collected through small\, controlled experiments with the individual as the unit of analysis – to the relative exclusion of the environment. Recent technological advancements facilitate massive amounts of data to be collected from diverse populations and locations. Capitalizing on these newly-available data\, researchers can geolocate the responses of individuals to provide insight into regional variation in intergroup biases with a degree of ecological validity impossible in the laboratory. In this talk\, I will present correlational evidence linking regional biases to outcomes of consequence\, propose a novel theoretical perspective for understanding regional intergroup bias\, and discuss future directions for this emerging line of research.
