10.00-11-00: Information search and decision making when judgment is suspended
Annika Wallin
Reader and Senior Lecturer in Cognitive Science
Department of Philosophy
Lund University
When information search and information evaluation are discussed these days, it is often done in relation to polarization, discussing issues such as confirmation bias or motivated reasoning. But also when decision makers have no strong prior opinion they eventually need to take sides. How can we best understand the process of information evaluation and information search when decision makers try to be impartial? One suggestion (stemming from so called coherence accounts) is that information that is encountered early on will have a stronger effect on subsequent decisions than information encountered later on, since latter information will be evaluated in the light of earlier information (eventually generating something akin to confirmation bias). Similarly, earlier information is suggested to steer information search, so that information confirming tentative early opinions is prioritized. However, studies suggest that when participants try to be impartial - such as when they are asked to make judicial decisions, information evaluation and information search diverge: latter information is, as suggested, evaluated in light of earlier information - so that confirming information is given a higher weight, but information search remains unbiased - which participants sometimes even actively searching for disconfirming evidence. In the talk I discuss why this might be, and discuss potential ways to study these different processes.

09.00-10.00: In search of cognitive aging biomarkers: Evaluating blood-based markers for prediction of long-term cognitive outcomes
Sara Pudas
Research fellow at Department of Integrative Medical Biology (IMB)
Umeå University
With an aging population, the search for preventive strategies for aging-related cognitive decline and dementia gets increasingly important. Finding biomarkers capable of predicting between-person differences in degree of brain and cognitive declines in aging individuals is an important step towards mechanistic understanding and prevention. This talk will cover some of our recent findings on two cellular aging biomarkers, telomere length and DNA-methylation, for prediction of long-term cognitive outcomes and dementia in a population-based cohort of older individuals. Both telomere length and DNA-methylation can be non-invasively measured in blood, and have been put forth as markers of the ‘biological age’ of individuals - which can differ considerably from their chronological ages. While our findings show some usefulness for these biomarkers, they also highlight differential predictive ability for different outcomes and in different subgroups of individuals. General challenges and possibilities for neurocognitive aging biomarkers will be discussed, as well as possible future directions towards personalized prediction strategies.

When Apes and Children Disagree
Cathal O'Madagain
Scientific Director, School of Collective Intelligence
Université Mohammed VI Polytechnique, Morocco
When we understand that the truth about the world is independent of our beliefs, we often double-check our evidence before making a final decision - knowing that we might be wrong. We also double-check our evidence if others disagree with us - knowing that if we believe opposite things, then one of us must be wrong. Here I present studies showing that young children and apes are sensitive to some of these distinctions, and highlighting that one of the hallmarks of human cognition is its sociality.

That the future of humanity rests on the veracity and completeness of human knowledge is no understatement. While the majority of people are curious and correctly update their knowledge with experience, we are nevertheless increasingly aware of the fragility and susceptibility of knowledge to information bubbles and conspiracies in the internet age. The purpose of this talk is to use AI-inspired computational theory and Cognitive experiments to shed light on the basic processes underlying knowledge updating. I will develop knowledge acquisition and updating as an intrinsic motive also known as curiosity. I use results from Machine Learning theory and AI to discuss knowledge representation, uncertainty, coherence and the potential and limitations for learning correct models of the world from experience. I highlight the real possibility of inconsistency of updating when prior knowledge is misspecified or erroneous. In particular, when new information conflicts with prior knowledge, three things can happen: 1) update anyway, replacing prior with new information. 2) Discard new information and keep the prior. 3) Keep prior and clone a new model which incorporates the new information, producing multiple schema. These scenarios correspond to improvement (assuming new information is correct), information bubbles, and knowledge fragmentation respectively. I next explain how a generalized update suggested by Grüwald and van Ommen can help mitigate these effects, resulting in a weighted update between prior knowledge and incoming information based on estimates of the reliabilities of each. We show strong evidence for this type of weighted update in experimental data from a Synonymy task, where we elicit prior knowledge, assess curiosity and memory efficacy after feedback. The results demonstrate that people on average have an accurate understanding of the reliability of their own knowledge, which drives their curiosity, and they incorporate new information to the extent they trust it more than their own knowledge. These results suggest that people are rationally incorporating information within the theoretical limits on learning systems. Time permitting, I will conclude by discussing actionable insights these results provide for addressing the burgeoning misinformation problem.
The constraints that bind us:
Insights from a dynamical systems perspective on human coordination
Maurice Lamb, PhD
Senior Lecturer in Informatics
School of Informatics, University of Skövde
May 21, 2021, 14.00-15.00 (CET)
Human-human coordination is the basis for many everyday tasks, whether it is unloading a dishwasher with a partner or walking down a busy sidewalk. It is not uncommon to view much of this coordination as depending on or even requiring cognitive systems for detailed planning and representation. There is almost certainly some truth to this assumption. However, this assumption can also obscure the ways in which many human coordinative actions may be lawfully grounded by the constraints of the physical world we live in. Complex dynamical systems approaches to understanding human cognition investigate human coordination by exploring how much coordination we can account for with relatively simple systems. In extremely oversimplified terms: If sets of oscillators coupled together exhibit the same pattern of coordination as exhibited by the gait patterns of humans walking together, why assume that human coordination in this context requires something additional? I will outline one contemporary understanding of complex dynamical systems theories as it relates to human coordination and provide examples of the kinds of insights and applications that may come from taking this perspective.
Understanding indirect speech acts:
Investigating individual differences with fMRI
Julia Uddén, PhD
Pro Futura fellow and Assistant Professor

Being able to communicate face-to-face with another person requires skills that go beyond core language abilities. In dialog comprehension, we routinely make inferences beyond the literal meaning of utterances. For instance, the utterance "it is hot in here" will in some circumstances mean "can you open the window?". This would be an example of a so-called indirect speech act. It is however not known whether communicative skills such as recognizing speech acts potentially overlap with core language skills or other capacities, such as Theory of Mind (ToM). I will talk about an fMRI study where we investigate these questions by capitalizing on individual variation in pragmatic skills in the general population. In the scanner, participants listened to dialogs, and the analysis strategy was based on differentiating brain activity associated with direct vs indirect speech acts, and finding individual differences in brain activity that corresponded to behavioral performance. Based on the results, I will argue that contextualized and multimodal communication requires neurocognitive networks different from those associated with core language, ToM/complex emotion processing, and cognitive control.
