Cracking the Code: Unveiling Hidden Patterns in Words, Speech, and Objects Through Implicit Statistical Learning

Abstract:
Humans possess remarkable abilities to learn new words, acquire language, and recognize objects based on sparse and ambiguous inputs. These abilities are rooted in the robust and efficient learning mechanism of statistical learning, which enables individuals to automatically detect regularities in their environment through exposure to multiple stimuli. Despite decades of research demonstrating the involvement of statistical learning in the formation of memory and internal models of prediction, the cognitive and neural mechanisms underpinning statistical learning remain unclear.
In this talk, I will share my team’s research on statistical learning over the past decade and discuss a series of behavioral and neurophysiological experiments designed to address newly emerging questions that uncover how statistical learning functions in the human brain across various encoding contexts. Specifically, I will address three fundamental questions: 1) Is statistical learning disrupted in individuals with neurodevelopmental disorders, especially dyslexia?; 2) How do different types of statistical learning change across ages and interact with other cognitive functions?; and 3) What cognitive and neural mechanisms support statistical learning?
In conclusion, I aim to demonstrate how new paradigms and theoretical frameworks are necessary to advance our understanding of how humans comprehend the probabilistic world, the mind, and the increasingly complex relationships between people and machines.

Computational passive bioacoustics: Will AI really solve animal communication?
2025-01-20 11:00 - 12:00 | Salle des voûtes, St Charles, 3 place Victor Hugo, Marseille, 13001, France
Paul Best (Eq. Multisense & Body) has been awarded an 2024 ILCB post-doc grant to work on the topic of spatialised bioacoustics for the analysis of turn-taking in non-human interactions. Paul’s original background is in computer science and machine learning. During his PhD and post-doc in Toulon university, he worked on automating the analysis of non-human vocalisations using neural networks. Paul has applied these methods to a range of species with a variety of research questions, always working with long-term acoustic data recordings of free-ranging animals. Some of these projects include analysing the presence patterns of sperm whales, characterising the evolution of song structure in fin whales, and linking communicative complexity to sociality in orcas. Currently at CRPN, Paul is working with recordings of pilot whales and cao-vit gibbons, with a focus on how contextualising passive acoustic data with spatial information (the location of the vocalising animal) contributes to a better understanding of their vocal behaviour.
Abstract:
For this seminar, we will look at current research in passive bioacoustics, especially regarding opportunities and limitations of using machine learning to study non-human communication. With the increasing use of long-term monitoring systems such as autonomous acoustic recorders, the relatively young and growing field of computational passive bioacoustic is promising in collecting naturalistic data to contribute to ethological and evolutionary questions. Drawing on my research experience and project in this domain, I will present what is and could be possible with such approach, including with the use self-supervised learning, case studies of cetacean communication systems, the benefits of sound localisation and the relevance of integrating a musical perspective in the study of non-human communication.

Different bodies, different minds: Biology as a central driving force in the building of cognitive functions?

Abstract:
By focusing on language, I will try to show that cognitive architectures are built from goal-driven perceiving and acting bodies in their physical environment, a perceptive that holds for humans as well as other animals. To illustrate this theoretical position, firstly, I will show in humans that words conveying time information are tightly linked to body mouvements (Camille Grasso’s PhD thesis), that syntax is probably built on domain-general fine motor planification (Raphaël Py’s PhD thesis), that our lexica are grafted onto sensorimotor networks (Melissa Yavuz’s PhD thesis, Anna Poberezhnaia master’s thesis, Anne Kavounoudias collab.). Secondly, I will describe the approaches of Lise-Habib Dassetto (PhD) and Paul Best (Postdoc) that address the questions of how communicative systems appeared during evolution and what kind of method we can develop to conduct fair comparisons between humans and baboons (Lise H.D.) or pilot-whales (Paul B.).

Between the shores of sleep and wakefulness: from sleep-wake regulation to subjective experiences
Despite its apparently quiet nature and homogeneous nature, sleep is a markedly heterogeneous state with respect to biological functions, neurophysiological properties, information processing and mental experiences. The sleeping brain is constantly monitoring the balance between the internal homeostatic demands and the need to monitor the external environment in order to detect potential threats or relevant information. Far from passive, the sleeping brain continually negotiates between internal homeostatic needs and the imperative to remain attuned to the external world, in case of threats or salient stimuli. In doing so, it oscillates along a dynamic continuum between deeper, disconnected states and lighter phases marked by heightened information processing. Oneiric (dream) experiences seem to take part in this process and reflect the underlying cyclic patterns of sleep and wake regulation. Are dreams simply epiphenomena or inherent aspects of the sleeping brain? Do they reflect random neural activations or convey personally meaningful information? In this talk, I will explore these questions through the lens of contemporary dream science and cognitive neuroscience, integrating insights from interdisciplinary fields such as neuropsychoanalysis and consciousness research.

Multidimensional Semantics for Concrete and Abstract Concepts

Multiple representation theories posit that concepts are represented via a combination of properties derived from sensorimotor, affective, linguistic, and other experiences. One advantage of this approach is that it helps address the challenge of abstract meanings, like wisdom and friendship, which are central to our mental and social lives and yet cannot be directly experienced through the senses. I will describe a series of studies in which my colleagues and I have tested predictions of multiple representation theories for acquisition and processing of concrete and abstract word meanings, exploring the roles of sensorimotor, interoceptive, and social experience. The development of large-scale word norms and behavioural megastudies has enabled consideration of multiple lexical and semantic dimensions and exploration of the possibility that these dimensions have simultaneous and interacting effects on behaviour. Using these “big data” I will consider how these multiple factors might be mapped in semantic space.
