[Koglist] [CEU Cogsci Talks] REMINDER -- CEU Departmental Colloquium, June 27: Cathal O'Madagain (Ecole Normale Superieure) - Developmental Origins of Objectivity

by Denis Tatone

Dear all, This is to remind of you today's colloquium. *Cathal O'Madagain* (Ecole Normale Superieure) [web <https://sites.google.com/site/cathalcom/cv2>] <http:> Title: *Developmental Origins of Objectivity* Date: Wednesday, 27 June 2018 Time: 17:00-18:30 Location: Department of Cognitive Science, CEU, Oktober 6 st. 7, room 101 Abstract: A concept that we repeatedly lean on as scientists is that of objectivity: the idea that the facts are independent of anyone’s beliefs. This is what motivates us to look for evidence that might confirm or disconfirm a hypothesis, and why we have a ‘reliability coder’ double-check our observations; it might even be said that science is unintelligible without invoking the concept of objectivity. What is the developmental origin of this concept? Here I explore the development of false belief understanding – a key component of the concept – and raise challenges for whether tests developed so far should be thought to really get at an understanding of objectivity. I then present preliminary results from a new study that aims to get closer to a general test for objectivity – a test that requires participants to understand that ‘anyone can be wrong’ about the facts. I end with some considerations for how language and social interaction may play a role in the development of this concept. We are looking forward to see you.

[Koglist] Meghívó Michael Kahana előadására - szerda 10.00

by Gaál Zsófia Anna

Tisztelt Kollégák! Az MTA TTK Kognitív Idegtudományi és Pszichológiai Intézete szeretettel hív minden érdeklődőt Michael Kahana professzor (University of Pennsylvania) előadására. Az előadás címe: Memory networks in the human brain Időpont: 2018. június 13. (szerda) 10 óra Helyszín: MTA TTK Kisterem (1117 Bp., Magyar Tudósok körútja 2.) Human memory function is highly variable, fluctuating between periods of high and low performance even within a given person. Neurosurgical patients with indwelling electrodes present a unique opportunity to study the neural correlates of this variability and to define both the features of neural activity at a given brain location and the functional connections between brain regions that predict variability in memory encoding and retrieval. Here, I will describe our recent efforts to characterize brain networks that support memory via correlative (passive neural recording) and causal (direct electrical stimulation) approaches. Moreover, I discuss unifying motifs in human electrophysiology that were revealed through these studies. Briefly, we have characterized functional, memory-related networks at multiple spatial scales, demonstrating that low-frequency signals exhibit reduced local power but stronger functional connectivity during successful episodic encoding and retrieval. Furthermore, many canonical memory regions emerge as hubs of such low-frequency connections, including the lateral frontotemporal cortices, the parahippocampal gyrus – and within it – the entorhinal cortex. High-frequency bands (i.e. gamma, 30+ Hz) almost exclusively exhibit desynchronization during successful memory operations. We recently extended these correlative studies and used intracranial stimulation to ask whether functional connections imply causality. We confirmed that electrical stimulation within the MTL evokes increases in theta power at remote regions, as predicted by the strength of low-frequency functional connections. However, this relationship held true only so long as stimulation occurred in or near white matter. These findings demonstrate the importance of low-frequency connectivity to episodic memory, integrating these findings over spatial scales and through causal and correlative approaches. I will also discuss the role of high (gamma) frequency activity and its role as a biomarker of increased local activity supporting memory and other cognitive functions.

[Koglist] [CEU Cogsci Talks] A talk by Tobias Donner (University Medical Center Hamburg) on Understanding Variability in Brain and Behavior - next Wednesday, June 20, 2018

by Gyorgyne Finta

Dear all, The CEU Department of Cognitive Science cordially invites you to its talk by: Tobias Donner<http://wordpress.tobiasdonner.net/people/#1449583052223-5787cafe-c538> (Dept. of Neurophysiology & Pathophysiology, University Medical Center Hamburg-Eppendorf) Date: Wednesday, June 20, 2018 - 17:00-18:30 Host: Jozsef Fiser Location: Department of Cognitive Science, CEU, Oktober 6 street 7, room 101. Understanding Variability in Brain and Behavior Variability is a pervasive feature of neural activity and behavior. Several theories postulate that variability is fundamental for adaptive brain function. I propose that understanding the sources and functional role of neural variability requires partitioning the variability of observed behavior. One partition is, in fact, only "apparent variability": it is caused by dynamic variations in systematic decision biases (not decision noise), which have remained hidden in many experiments. Only the second partition is "genuine variability", resulting from the inherent variability in the activity of cortical neurons. To support this claim, I will present recent work from my laboratory focusing on perceptual decision-making under uncertainty. We find that a large portion of the variability in perceptual choice behavior can be explained by dynamic trial-to-trial modulations of decision biases: apparent variability. Those bias modulations are induced by the history of previous choices as well as by phasic arousal transients during decision formation. They are implemented by systematic modulations of the underlying cortical activity states. In another line of work, we show that the level of genuine variability in perceptual choice is controlled by a major neuromodulatory system - the norepinephrine system - likely through altering the balance between excitation and inhibition in cortical networks. This line of work points to an adaptive function of noise in perceptual inference. I conclude that pinpointing the factors governing apparent behavioral variability and identifying control mechanisms for genuine behavioral variability will enable a deeper understanding of brain function.

[Koglist] [CEU Cogsci Talks] CEU Departmental Colloquium, June 13: Lori Markson (Washington University) - Children’s reasoning about social exclusion

by Denis Tatone

The CEU Department of Cognitive Science cordially invites you to its talk by: Prof. *Lori Markson* (Washington University) [web <https://pages.wustl.edu/children>] Title: *Children’s reasoning about social exclusion* Date: Wednesday, 13 June 2018 Time: 17:00-18:30 Location: Department of Cognitive Science, CEU, Oktober 6 st. 7, room 101 Abstract: The basic human need to belong has an evolutionary basis and is largely universal. The awareness of and ability to evaluate social interactions appears to emerge in infancy. Infants discriminate between positive and negatively valence interactions and even recognize dominance hierarchies in their observations of third-party interactions. However, there has been less research on the emergence of the motivation to seek acceptance and avoid rejection. I will present some of our work exploring the developmental trajectory of children’s early reasoning about the social dynamics of inclusion and exclusion. Our findings suggest that by three years of age, children begin to differentiate between excluders and those who have been excluded based on their intentions and interactions. The results will be discussed in the context of a broader theoretical framework for thinking about the emergence and development of the human sensitivity to social exclusion. We are looking forward to see you.
