Abstract
Existing sampling methods in language typology strive to control for areal biases in typological datasets as a means to avoid contact effects in the distribution of linguistic structure. However, none of these methods provide ways to directly compare contact scenarios from a typological perspective. This paper addresses this gap by introducing a sampling procedure for worldwide comparisons of language contact scenarios. The sampling unit consists of sets of three languages. The Focus Language is the language whose structures we examine in search for contact effects; the Neighbor Language is genealogically unrelated to the Focus Language, and counts as the potential source of contact influence on the Focus Language; the Benchmark Language is a relative of the Focus Language neither in contact with the Focus nor with the Neighbor language, and is used for disentangling contact effects from genealogical inheritance in the Focus Language. Through this design, we compiled a sample of 49 three-language sets (147 languages in total), which we present here (GramAdapt project). By switching the focus of typological sampling from individual languages to contact relations between languages, our method has the potential of uncovering patterns in the diffusion of language structures, and how they vary and change.

Learning to read with Neurofibromatosis Type 1

We are pleased to share with you the latest article published in the journal Vision Research by Marie Vernet (ToNIC / LPL / CLLE) and Stéphanie Ducrot (LPL) in collaboration with colleagues from Aix, Montpellier and Toulouse:

The determinants of saccade targeting strategy in neurodevelopmental disorders: The influence of suboptimal reading experience. Vision Research, 204, 108162 https://doi.org/10.1016/j.visres.2022.108162

Abstract: Whether eye-movements deficits are causal in reading disorders (RD) or rather a consequence of linguistic processing difficulty experienced by disabled readers has been extensively debated.Since RD are frequently comorbid with the Neurofibromatosis type1 (NF1), children with NF1 were used as a comparison group for children with dyslexia in this study.Eye movements were recorded while 21 dyslexic, 20 NF1, and 20 typically developing children performed an oculomotor lateralized bisection task. In this experiment, we manipulated the type of stimulus - discrete (words and strings of hashes) versus continuous (solid lines) - and the visual field where the stimulus was displayed (left vs right). The results showed that (1) only proficient readers (TD and NF1 without RD) showed fully developed oculomotor mechanisms for efficient reading, with a clear preferred viewing location located to the left of the word's centre in both visual fields, and fine-tuned saccade targeting guided by the between-character space information and (2) NF1 poor readers mirrored the dyslexic eye movement behaviour, with less accuracy and more variability in saccadic programming, no sensitivity to the discreteness of the stimuli, particularly in the left visual field. We concluded that disruption to oculomotor behaviour reflectsthe fact that many of the processes involved in reading are not yet automatized for children with RD, independently of NF1. This suggests that the differences in saccade targeting strategy between children with and without RD would be secondary consequences of their reduced reading experience.

Challenges and new perspectives of developmental cognitive EEG studies

As part of the 80PRIME « LangDev » project and Estelle Hervé's thesis, a fine review of electroencephalography with babies has just been published in the prestigious journal NeuroImage. The article offers an overview of the challenges and technical and methodological solutions necessary to make the best use of EEG in research on early cognitive development. Other colleagues have contributed to the publication, such as Clément François, CNRS researcher at LPL and co-director of Estelle’s thesis.

What babies’ laughter tells us about their cognitive development

We are pleased to announce the publication of the latest article by Chiara Mazzocconi (ILCB/LPL) – as first author – and Jonathan Ginzburg (LLF Paris) in the Journal of Nonverbal Behavior:

Mazzocconi, C., Ginzburg, J. A Longitudinal Characterization of Typical Laughter Development in Mother–Child Interaction from 12 to 36 Months: Formal Features and Reciprocal Responsiveness. J Nonverbal Behav (2022). https://doi.org/10.1007/s10919-022-00403-8

Full text access: https://rdcu.be/cTdZe

Abstract:
In our study we looked at laughter development in mother-child natural interaction from 12 to 36 months. We showed that babies laugh less than mothers (and adults more generally) and that responsiveness to mothers’ laughter increases over time. On the other hand we observe mothers reinforcing child laughter similarly to other speech-like vocalizations, and adapting their contingent responses to the developmental stage of the child. Our study shows the importance of laughter in early interactions highlighting how its production and responsiveness to others’ laughter can be informative about the neuro-psychological development of babies.

Good to know: Chiara will give a mini-conference around this research theme during the LPL Open House Day on Saturday, October 15 (information in French)! 😉

Do you choose your words depending on who you’re talking to (even when your partner is a robot)?

Giusy Cirillo (PhD student LPL/ILCB) has just published - as 1st author and in collaboration with other members of the LPL and Barcelona University - an article in the Cognition journal on inter-individual alignment in spoken communication.

Giusy Cirillo, Elin Runnqvist, Kristof Strijkers, Noël Nguyen, Cristina Baus. Conceptual alignment in a joint picture-naming task performed with a social robot. Cognition, Elsevier, 2022, 227, p. 105213. ⟨10.1016/j.cognition.2022.105213⟩

Abstract:

In this study we investigated whether people conceptually align when performing a language task together with a robot. In a joint picture-naming task, 24 French native speakers took turns with a robot in naming images of objects belonging to fifteen different semantic categories. For a subset of those semantic categories, the robot was programmed to produce the superordinate, semantic category name (e.g., fruit) instead of the more typical basic-level name associated with an object (e.g., pear). Importantly, while semantic categories were shared between the participant and the robot (e.g., fruits), different objects were assigned to each of them (e.g., the object of ‘a pear’ for the robot and of ‘an apple’ for the participant). Logistic regression models on participants' responses revealed that they aligned with the conceptual choices of the robot, producing over the course of the experiment more superordinate names (e.g., saying ‘fruit’ to the picture of an ‘apple’) for those objects belonging to the same semantic category as where the robot produced a superordinate name (e.g., saying ‘fruit’ to the picture of a ‘pear’). These results provide evidence for conceptual alignment affecting speakers' word choices as a result of adaptation to the partner, even when the partner is a robot.
