Online Seminar - Visual perception of social relationship

Liuba Papeo - Institut des Sciences Cognitives—Marc Jeannerod, UMR5229 ,Centre National de la Recherche Scientifique (CNRS) & Université Claude Bernard Lyon 1


26 JAN 2022
16:30 - 18:00

Description :


The social function of human vision appears clear from the highly specialized mechanisms for face and body perception. Here, I address the social function of vision with respect to the representation of human groups and their relationships.
I will present a set of behavioral, fMRI and EEG studies addressing how the representation of social interaction emerges from object perception, through the analysis of spatial relations between multiple faces and bodies in visual scenes.
First, I will discuss new behavioral phenomena suggesting that human vision encodes socially relevant spatial relations between people (i.e., bodies) with the same efficiency and high specialization of face perception. Second, I will discuss how a network of visual brain areas may give rise to the earliest rudimentary representation of social interaction, based on the mere physical structure of the input, before inferential processes kick in.

liuba papeo is inviting you to a scheduled Zoom meeting.

Online Seminar - Spontaneous activity, memory replay, and the default mode network

Dr. Majid Mohajerani, Associate Professor, University of Lethbridge


5 JAN 2022
17:30 - 19:00

Description :


Spontaneous activity accounts for most of what the brain does and is likely to be key for information processing in the brain, but its function is still quite mysterious. Two key spontaneous activity processes are the Default Mode Network (DMN), a set of areas that are most markedly connected and active during behavioural idleness, and memory replay, the spontaneous reactivation of neural patterns occurring during experience. In the Mohajerani lab, we test the hypothesis that the DMN plays a key role in memory replay processes. This theory, if confirmed, would bring important conceptual advances: to memory studies, as it would provide a mechanism supporting the formation and consolidation of complex memory representations. I will explore this theory by our ongoing studies of neural activity over the whole mouse cortex in animals running memory tasks.

Online Seminar - How fast are responses to “is it funny” and “is it strange” questions?

Alessio Toraldo, Associate Professor at University of Pavia, Italy


22 DEC 2021
16:00 - 17:30

Description :


We aimed at investigating humor empirically by applying a cognitive-psychology approach, thus focusing on a specific humor task. Thirty-two participants listened to 30 jokes intermixed with 30 non-jokes that had an implausible ending, and decided whether or not each stimulus was funny (Humor Decision Task, HDT). In a control task, 30 plausible stories and 30 stories with an implausible ending were intermixed and participants decided whether or not each stimulus was “strange” (Implausibility Decision Task, IDT). Response times (RT) on correct responses indicated that the two tasks involve different cognitive operations: while “funny” responses were 256 ms faster than “not-funny” responses, “strange” responses took the same time as “not-strange” ones. IDT results could be explained by assuming that participants used the degree of semantic overlap between the setup and the ending of the story to select a response. As for HDT, we had two different cognitive accounts, the “recognition” and the “sequential attempts” hypotheses. On the former, participants activate long-term-memory (LTM) abstract representations of the jokes’ semantic structures; on the latter, participants use a trial-and-error strategy to solve the puzzle posed by a punchline that is not already available in LTM. RT on incorrect responses favoured the “sequential attempts” hypothesis.

Online Seminar - Functional architecture of cerebral cortex during naturalistic movie-watching

Reza Rajimehr , University of Cambridge , MRC Cognition and Brain Sciences Unit


15 DEC 2021
18:00 - 19:30

Description :


Characterizing the functional organization of cerebral cortex is a fundamental step in understanding how different kinds of information are processed in the brain. Monumental efforts over the past decades have uncovered the function of many cortical areas in response to selected stimulus categories. However, it is still unclear how cortical areas are organized during naturalistic vision and audition. Here we used high-resolution functional MRI data from 176 human subjects to map the macro-architecture of entire cerebral cortex based on responses to a 60-minute audiovisual movie stimulus. A data-driven clustering approach revealed a map of 24 functional areas/networks, each related to a specific aspect of sensory or cognitive processing. The map included three distinct executive control (domain-general) networks which showed a strong push-pull interaction with domain-specific regions in visual, auditory, and language cortex. The cortical parcellation scheme presented here provides a comprehensive and unified map of functionally defined areas, which could replace a large set of functional localizer maps.

Online Seminar - Ecological perspectives on the neural machinery for communication and cooperation

Dr. Samuel Nastase , Princeton University


24 NOV 2021
16:30 - 18:00

Description :


ECognitive neuroscientists are trained to use clever experimental manipulations to decompose complex cognitive phenomena—like language—into simpler, more manageable components. Drawing on parallels with machine learning and evolutionary biology, I advocate for a complementary approach that puts ecological considerations at the forefront. To make this more concrete, I provide two examples of this approach from my own work. First, I introduce the "Narratives" data collection—a well-curated community benchmark dataset comprising over 800 naturalistic fMRI scans acquired while participants listened to a variety of spoken narratives. I'll touch on some recent results emerging from this dataset using deep language models to capture brain activity during narrative comprehension. Second, I briefly discuss ongoing work using deep neural networks as "model organisms" for understanding brain-to-brain coupling and cooperative behavior in an artificial gameplay ecosystem.

Seminar - Integrated Cognitive Assessment for Timely Diagnosis of Mild Cognitive Impairment and Alzheimer's Disease

Dr. Seyed Mahdi Khaligh Razavi , Royan Institute


8 NOV 2021
10:00 - 11:30

Description :


Early detection and monitoring of mild cognitive impairment (MCI) and Alzheimer's Disease (AD) patients are key to tackling dementia and providing benefits to patients, caregivers, healthcare providers and society. Digital biomarkers can help identify and monitor subtle cognitive changes in individuals at risk of developing dementia. Furthermore, such tests are able to benefit from advanced analytics for more accurate and personalised results. Artificial intelligence (AI) and machine learning are being increasingly used for applications in Dementia research. We developed the Integrated Cognitive Assessment (ICA) which is a 5-min, self-administered, computerised cognitive assessment tool based on a rapid categorisation task. The ICA is innately independent of language and culture, and can generalise across populations without the need for collection of population-specific normative data. ICA has received CE approval for use in Europe and is cleared by FDA for use in the US. After more than 28 years of symptom therapy in AD, new disease modifying therapies are becoming available which are only effective in early stages of the disease. This further emphasizes the importance of early diagnosis, and highlights the benefits of emerging technologies such as ICA a practical solution to the significant and urgent problem of timely dementia diagnosis.

* I will give a brief summary of Cognetivity's journey so far and walk you through some of the key findings from our research publications and clinical investigations.

IPM SCS Webinar

The Contextual Effect On Value Learning Procedure

Dr. Zahra Barakchian , School of Cognitive Sciences, IPM


28 OCT 2021
17:00 -

IPM SCS Webinar

Abstract:


Numerous surveys and surveys over the past two decades show that 60 to 80% of companies do not achieve their strategic goals. When we talk about strategic management, we consider the three stages of strategy development, implementation, and evaluation as the main stages, and we consider strategic management as a technical process, step by step and stages that from the development of orientation pillars begins with environmental analysis and surveys and the development of strategies continues and ends with specific operational measures. In recent years, many strategic plans have been developed with the same approach in organizations, but as stated and research shows that many of these plans in practice and especially in achieving goals and influencing Key performance variables of the organization have failed. The success of organizations in dynamic and uncertain market conditions requires managers who have special capabilities to create value creation methods and modify previous ways and methods and have a deep understanding of the complexity of cause-and-effect relationships between market variables and components. Branches and disciplines such as behavioral strategy and cognitive psychology refer to these competencies as managers 'cognitive competence and strategic management thinkers consider managers' cognitive competence as the basis of the organization's dynamic capabilities. Having a behavioral view of strategy paves the way for improving the effectiveness of strategies in the field of operations. We have to accept that the strategic management process is not just a technical process, and the cognitive abilities of managers in this area can play an effective role in promoting the effectiveness of strategic plans. This webinar seeks to provide a model and framework to explain the role of managers' cognitive abilities in implementing strategies.
