Behaviors and disorders related to problems in self-regulation, such as substance use disorders, childhood behavior problems, and adult antisocial behavior are collectively referred to as Externalizing. In this talk, I will describe research that pooled information on multiple forms of externalizing behavior in ~1.5 million people and identified more than 500 genetic loci associated with a general liability to Externalizing.

How the human brain specialized for language and cognition is a fundamental question for the brain sciences. In essence the key question is: what makes us unique? In this talk, I first consider new evidence from structural and effective connectivity studies in human and nonhuman primates, leading to a different way of thinking about how the human arcuate fasciculus and fronto-temporal brain system evolved.

Ce sont ses fonctions de Directeur des études sciences à l’ENS qui ont conduit Christian Lorenzi, il y a quelques années, à s’interroger sur la possibilité d’appliquer les théories et méthodes de la « psychophysique » - cette branche de la psychologie expérimentale étudiant scientifiquement les relations entre les signaux physiques (e.g., les sons) et nos sensations ains

Adolescence, defined as 10-24 years, is a period of life often characterised by behaviours that can appear, prima facie, irrational such as dangerous risk-taking and impulsivity. However, these behaviours can be interpreted as adaptive and rational given that a key developmental goal of this period of life is to mature into an independent adult while navigating a social world that is unstable and changing.

Western history of thought abounds with claims that knowledge is valued and sought. Yet people often choose not to know. We call the conscious choice not to seek or use knowledge (or information) deliberate ignorance. Using examples from a wide range of domains, we demonstrate that deliberate ignorance has important functions. We systematize types of deliberate ignorance, describe their functions, discuss their normative desirability, and consider how they can be modeled.

Axelle Calcus s’intéresse de près à la perception auditive chez l’enfant et au lien qui existe entre perception de la parole, acquisition du langage et performance scolaire. Elle travaille tout particulièrement sur le développement des habiletés de perception de la parole dans le bruit.

Les recherches de Giovanni Di Liberto au sein du LSP portent sur la compréhension des mécanismes cérébraux sous-jacents à la perception de sons complexes, tels que la parole et la musique. Le cerveau humain contient des milliards de neurones qui interagissent les uns avec les autres au moyen de signaux électriques.

Denis Lancelin est ingénieur d’étude au CNRS au Laboratoire des Systèmes Perceptifs (LSP). Les membres de cette unité cherchent à mieux comprendre les mécanismes sous-jacents à notre perception du monde, avec une emphase sur la vision et l’audition. Denis participe à ces recherches en apportant un soutien technique et administratif.

Thermal soaring is a major natural instance of animal behavior in the presence of complex orientation cues. The problem is deeply rooted in physics and biology, with the prowess by birds constituting a challenge for artificial systems built for technological applications. I will first introduce the natural phenomenology, then review the physics that controls the complexity of the orientation cues, and finally show how machine learning methods are brought to bear on identifying effective flying strategies.

Brian CJ Moore will do us the honor of presenting his scientific achievements and an overview of his magnificent scientific career.

This conference is organized by Prof Christian Lorenzi and Dr Léo Varnet (Laboratoire des Systèmes Perceptifs).
