Workshop "1001 ways of communicating"

Campus St Charles, salle des voûtes

Dear colleagues,

We are running a thematic workshop entitled the 1001 ways of communicating, here in Saint Charles on 7th February 2020 (all day). We've got an excellent line of external speakers and local speakers that will talk about the major sensorimotor and cognitive acquisitions underlying the ability to communicate in pre- and non-verbal populations (infants and animals).

The preliminary program and link for registration are available at: https://1001waysofcom.wordpress.com. Registration is free but spaces may be limited.

We hope to see you there! (and sorry for cross-posting)

How working memory guides attention: From lab to life

When I'm looking for a red coffee cup, my gaze is automatically drawn towards other red objects. This happens because the color red (and other features of the coffee cup) serves as an "attentional template", and objects that match this template automatically attract attention. But what exactly is an attentional template? After all, giving something a name doesn't explain it. And are attentional templates artificial lab phenomena, or do they also play a role in real-life situations? In this talk, I will describe a series of studies, building on the work that I started at the LPC, in which we've tried to address these questions.

Language evolution: communication and cognition

 

Anne Reboul, DR CNRS,  Institute for Cognitive Sciences-Marc Jeannerod, CNRS UMR 5304

I will quickly outline the type of research that I have done throughout my scientific life, with a special attention to recent work, mostly on the topic of language evolution. The two main questions regarding language evolution are to what extent abilities which are strongly linked to language in humans are also present in nonhuman animals, notably primates and also why, if they are found in nonhuman primates, language (seen as a whole) seems to be species specific. By now, everyone (including Chomsky) agrees that language is a collection of abilities (notwithstanding the distinction between the Faculty of Language in the Broad vs. in the Narrow Sense). In the Chomskyan paradigm, the idea is that the abilities in the FLB interact with the FLN which is reduced to a single simple syntactic operation, merge, and that these abilities can be divided between those relating to the externalization and those relating to the semantics of sentences. All of these abilities can be investigated as to whether or not they are found in nonhuman primates and have been so investigated notably by the Comparative Cognition team in the LPC. Interestingly, given that some theories saw language as strongly grounded in the vocal abilities of humans, it seems more and more obvious that at least some primate species share these abilities. Chomsky himself has consistently seen semantics (the so-called conceptual-intentional system) as more fundamental than externalization to language. I will explore the abilities that go into the conceptual-intentional system, some of which have already been investigated here at the LPC, and propose a few new lines of research.

How sighting eye dominance influences visual perception and oculomotor control

Résumé : Humans show several lateral preferences: they are more likely to choose a given hand, foot and eye when writing, kicking the ball and using a microscope. If handedness has repeatedly been shown to influence visual perception and visuo-motor performance, the role of other lateral preferences in perception and action is less understood. In this talk, I will present perceptual and motor asymmetries linked to sighting eye dominance. The sighting dominant eye, i.e., the one used to perform monocular tasks, is anatomically and functionally linked to the ipsilateral primary visual cortex (V1). As such, it is also linked to the contralateral visual hemifield. I will review recent behavioral findings showing that this anatomo-functional relationship between the dominant eye and ipsilateral V1 affects our performance in attentional and visuo-motor tasks. I will also show how the influence of eye dominance on visuo-motor performance can be used as a tool to quantify the strength of eye dominance (i.e., identifying individuals with strong or weak eye dominance), and how it co-exists with other perceptual and motor asymmetries. Lastly, I will discuss these behavioral findings in the light of the neurophysiological bases of eye dominance and oculomotor control, highlighting the importance of considering functional asymmetries when studying visual perception and visuo-motor behaviors.

A la Une

  1. Sciences Advances

    La parole pourrait être plus ancienne qu’on ne le croyait. Depuis 50 ans, la théorie de la « descente du larynx » avance qu’une position basse du larynx est nécessaire pour produire des voyelles différenciées, préalable à l’apparition de la parole. Les singes, qui ont une anatomie du conduit vocal qui ressemble, pour l’essentiel des articulateurs (langue, mandibule, lèvres), à celle des humains, mais avec un larynx haut, ne pourraient pas produire de vocalisations différenciées.

  4. Nature Human Behavior: How implicit biases create gender discrimination

    In an article in Nature Human Behavior, Isabelle Régner (Social Cognition team) and her colleagues show that committees with implicit biases promote fewer women when they do not believe gender bias exists. Even scientists have gender stereotypes … which can hamper the career of women researchers.

  5. How is the human brain unique?

    Although the relative expansion of the frontal cortex in primate evolution is generally accepted, the nature of the human uniqueness, if any, and between-species anatomo-functional comparisons of the frontal areas remain controversial. To provide a novel interpretation of the evolution of primate brains, sulcal morphological variability of the medial frontal cortex was assessed in Old World monkeys (macaque/baboon) and Hominoidea (chimpanzee/ human). We show that both Hominoidea possess a paracingulate sulcus, which was previously thought to be unique to the human brain and linked to higher cognitive functions, such as mentalizing.

  6. PNAS: Constraints on the lexicons of human languages have cognitive roots

    In an article in PNAS, Emmanuel Chemla (LSCP, CNRS, ENS) together with Isabelle Dautriche (Language team) and Joel Fagot (Comparative Cognition team) show that learning biases for connectedness are present in baboons, suggesting that the shape of the world’s languages (both content and logical words) has roots in general, nonlinguistic, cognitive biases.

  8. Grammatical class modulates the (left) inferior frontal gyrus within 100 milliseconds

    In an article in Scientific Reports, Francois-Xavier Alario (Language team) and colleagues showed showed rapid (from ~80 ms onwards) noun-verb differences in the left and (to a lesser extent) right inferior frontal gyri (IFG), but only when those nouns and verbs were preceded by the syntactically predictive context (i.e. their corresponding pronoun).This suggests that syntactic unification manifests very early on during processing in the LIFG. The speed of such syntactic unification operations is hypothesized to be driven by predictive top-down activations stemming from a domain-general network in the prefrontal cortex.
