Brice is a post-doctoral fellow at the LPL within the framework of the AMPIRIC-funded DREAM project, which aims to gain a better understanding of the factors involved in children's exposure to the written word in the first year of primary school, in order to develop a programme of personalised recommendations for learning to read. He coordinates this project together with Stéphanie Ducrot (LPL/CNRS).

New publication on multimodal and interactional humor

We are pleased to announce the publication of a new reference work on multimodal and interactional humor, coordinated by Béatrice Priego-Valverde, lecturer at AMU and member of the LPL.

Link to the publisher's website: https://www.degruyter.com/document/doi/10.1515/9783110983128/html

The central question explored in this volume is: How is humor multimodally produced, perceived, responded to, and negotiated? To this end, it offers a panorama of linguistic research on multimodal and interactional humor, based on different theoretical frameworks, corpora, and methodologies. Humor is considered as an activity that is interactionally achieved, regardless of whether the interaction in which it is embedded is face-to-face, computer-mediated, with a human or a robot, oral or written. The aim is to analyze both the linguistic resources of the participants (such as their lexicon, prosody, gestures, gazes, or smiles) and the semiotic resources that social networks and instant messaging platforms offer them (such as memes, gifs, or emojis).

SMAD: LPL software to measure the intensity of smile

We are pleased to announce the publication of the article "Automatic tool to annotate smile intensities in conversational face-to-face interactions" by Stéphane Rauzy (CNRS research engineer) and Mary Amoyal (former LPL doctoral student) in the journal Gesture.

It can be downloaded free of charge from the HAL platform: https://hal.science/hal-04194987/

This study presents an automatic tool that allows to trace smile intensities along a video record of conversational face-to-face interactions. The processed output proposes a sequence of adjusted time intervals labeled following the Smiling Intensity Scale ( Gironzetti, Attardo, and Pickering, 2016 ), a 5 levels scale varying from neutral facial expression to laughing smile. The underlying statistical model of this tool is trained on a manually annotated corpus of conversations featuring spontaneous facial expressions. This model will be detailed in this study. This tool can be used with benefits for annotating smile in interactions. The results are twofold. First, the evaluation reveals an observed agreement of 68% between manual and automatic annotations. Second, manually correcting the labels and interval boundaries of the automatic outputs reduces by a factor 10 the annotation time as compared with the time spent for manually annotating smile intensities without pretreatment. Our annotation engine makes use of the state-of-the-art toolbox OpenFace for tracking the face and for measuring the intensities of the facial Action Units of interest all along the video. The documentation and the scripts of our tool, the SMAD software, are available to download at the HMAD open source project URL page https://github.com/srauzy/HMAD.

A sampling technique for worldwide comparisons of language contact scenarios

Francesca Di Garbo (LPL/AMU) and Ricardo Napoleão de Souza (U. Helsinki/U. Edinburgh) have just published a new article in the journal Linguistic Typology which presents a new method for developing typological databases around language contact phenomena .

Di Garbo, Francesca and Napoleão de Souza, Ricardo. "A sampling technique for worldwide comparisons of language contact scenarios" Linguistic Typology, 2023.
https://doi.org/10.1515/lingty-2022-0005 / hal-03984522

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:

Reference: Vernet, M., Bellocchi, S., Danna, J., Massendari, D., Jover, M., Chaix, Y., Ducrot, S. (2023). 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.
