Experience & Publications

Here is an overview of my academic background and research projects in which I took part during my studies.

Research assistant (2021-2022)

I just started this academic year with a contract of research assistant at the Laboratoire Parole et Langage, under the direction of Dr. Elin Runnqvist. To read more about my current projects, see Research.

Master student (2019-2021)

I graduated from the MasCo program of the Institute of Language, Communication and Brain (ILCB) between 2019 and 2021. To complete my background in psychology and neuroscience, I specialized in linguistics through different classes such as prosody, phonetics, phonology, semantics, corpus, linguistic epistemology and pragmatics.

During the two year’s program, I had the chance to collaborate on various projects with professors, post-doctoral fellows, PhD candidates and master students. Some of them are highlighted below.

Language induced changes of mind

Master’s thesis (2021)

I completed my master thesis at the Laboratoire Parole et Langage under the direction of Dr. Elin Runnqvist and Dr. Amie Fairs, in collaboration with Pr. Guillaume Thierry from Bangor University. This study investigated the reorganization of perceptual categories following a short language learning experience.

A first goal was to investigate the interaction of previous labels with learning and potential language-induced effects on categorical perception. A second goal was to determine whether language-learning might make similar colours more distinctly perceived (within category separation) and/or more dissimilar colours less distinctly perceived (between category compression). A third goal was to assess whether potential effects would be persistent, indicating authentic learning and reorganization of the semantic space. In two experiments, native French participants were asked to learn new labels for two nuances of each of four hues. Across participants, we manipulated whether the colours had a previous robust label (ETN colours) or not (HTN colours). Linguistic similarity of labels for different nuances and hues was manipulated within participants. Speakers then had to rate the perceived similarity of colour pairs. Results showed that colours that had a previous robust label were persistently rated as more similar if they had similar new labels. These findings highlight 1) a key role of spreading activation and lexico-semantic strengthening induced by competition as a drive of second language learning, and 2) an impressive malleability of the human perception-based interpretation of the world.

Using virtual agents to fight social discriminations

Conference paper (Wacai, 2021)

Morgane Peirolo & Pr. Magalie Ochs

Virtual agents can be used to promote pro-social behaviour. In this short literature review, we explored the potential of virtual agents and virtual reality to fight social discriminations through empathy induction in the user. We present several systems developed in this perspective and discuss the factors of influence, measures of performance of those systems, as well as the current limitations of these works.

Domain-initial strengthening in Turkish: Acoustic cues to prosodic hierarchy in stop consonants

Conference paper (Interspeech, 2021)

Studies have shown that cross-linguistically, consonants at the left edge of higher-level prosodic boundaries tend to be more forcefully articulated than those at lower-level boundaries, a phenomenon known as domain-initial strengthening. This study tested whether similar effects occur in Turkish, using the Autosegmental-Metrical model proposed by Ipek & Jun (2013) as the basis for assessing boundary strength. Productions of /t/ and /d/ were elicited in four domain-initial prosodic positions corresponding to progressively higher-level boundaries: syllable, word, intermediate phrase, and Intonational Phrase. A fifth position, nuclear word, was included in order to better situate it within the prosodic hierarchy. Acoustic correlates of articulatory strength were measured, including closure duration for /d/ and /t/, as well as voice onset time and burst energy for /t/. Our results show that closure duration increases cumulatively from syllable to intermediate phrase, while voice onset time and burst energy are not influenced by boundary strength. These findings provide corroborating evidence for Ipek & Jun’s model, particularly for the distinction between word and intermediate phrase boundaries. Additionally, articulatory strength at the left edge of the nuclear word patterned closely with word-initial position, supporting the view that the nuclear word is not associated with a distinct phrasing domain.

Does the mobilization of the vocal tract vary according to languages in spontaneous speech?

Master’s internship (2020)

Conference paper (JEP TALN, 2020)

I completed my first year master internship at the Laboratoire Parole et Langage under the direction of Pr. Christine Meunier and Dr. Brigitte Bigi. The aim of this work was to quantify the theoretical articulatory positions during the production of spontaneous speech for three languages.

Each language has a specific phonological inventory. However, these specificities are not represented as such in spontaneous speech, in which phonemes do not have the same relative frequency. We compared three languages (Polish, French and American English) with notable differences in their phonological inventory. Articulatory positions were calculated according to phoneme frequencies in the three languages through spontaneous speech corpora. Surprisingly, the results tend to show that preferred articulatory positions are very similar in the three languages. Thus, it seems that spontaneous speech production, and therefore phonemes distribution in languages, erases the disparities of phonological systems in order to provide similar articulation. Further investigation should verify this observation.

Bachelor student (2016-2019)

I completed my Bachelor degree in Psychology at Aix-Marseille University, with a specialization in Behavioural neuroscience. To improve further my knowledge of neurobiological processes, I completed my studies with the two first years of a Bachelor degree in Life sciences, with a specialization in Physiology and Neuroscience at Aix-Marseille University.

Exchange student UdeM (2018-2019)

I completed the third year of my Bachelor degree in Psychology at the University of Montréal (UdeM) in Quebec, Canada.

Previous background

My previous studies involve classical letters, economy and cinema.

I obtained my Baccalaureate in 2010 in Litterature with a specialization in Film studies.
