Article
L1 French participants learned novel L2 English words over two days of learning sessions, with half of the words presented with their orthographic forms (Audio-Ortho) and half without (Audio only). One group heard the words pronounced by a single talker, while another group heard them pronounced by multiple talkers. On the third day, they completed...
Preprint
A central observation in the recognition memory literature is that neural processes occurring during encoding of stimuli are predictive of their later recognition. Compared to items that are later forgotten, encoding of correctly recognised items has been associated with greater amplitude between 400 ms and 800 ms post stimulus onset across centro-...
Article
The picture-word interference paradigm (participants name target pictures while ignoring distractor words) is often used to model the planning processes involved in word production. The participants' naming times are delayed in the presence of a distractor (general interference). The size of this effect depends on the relationship between the targe...
Preprint
The Complementary Learning Systems model of word learning proposes that newly learned words that have been integrated into semantic memory can interact with familiar words during lexical selection. The study reported here is the first to examine how behavioural markers of integration map onto electrophysiological markers of integration in a version...
Article
Full-text available
Studies of word production often make use of picture-naming tasks, including the picture-word-interference task. In this task, participants name pictures with superimposed distractor words. They typically need more time to name pictures when the distractor word is semantically related to the picture than when it is unrelated (the semantic interfere...

Article
Despite scarce empirical evidence, introducing new vocabulary in semantic categories has long been standard in second language teaching. We examined the effect of learning context on encoding, immediate recall and integration of new vocabulary into semantic memory by contrasting categorically related (novel names for familiar concepts blocked by se...
Article
Full-text available
Usage-based theories assume that all aspects of language processing are shaped by the distributional properties of the language. The frequency of words but also of larger chunks plays a major role in language processing. These theories predict that the frequency of phrases influences the time needed to prepare these phrases for production and their...
Article
This study investigates the production of nominal compounds (Experiment 1) and simple nouns (Experiment 2) in a picture-word interference (PWI) paradigm to test models of morpho-lexical representation and processing. The continuous electroencephalogram (EEG) was registered and event-related brain potentials [ERPs] were analyzed in addition to pictu...
Preprint
Individuals differ in the time it takes to produce words when naming a picture. However, it is unknown whether this inter-individual variability emerges in earlier stages of word production (e.g., lexical selection) or later stages (e.g., articulation). The current study measured participants' (N = 45) naming latencies and continuous EEG in a pictu...
Article
Full-text available
When participants in an experiment have to name pictures while ignoring distractor words superimposed on the picture or presented auditorily (i.e., picture-word interference paradigm), they take more time when the word to be named (or target) and distractor words are from the same semantic category (e.g., cat-dog). This experimental effect is known...
Preprint
In the picture-word interference paradigm, participants name pictures while ignoring a written or spoken distractor word. Naming times to the pictures are slowed down by the presence of the distractor word. Various properties of the distractor modulate this slow down, for example naming times are shorter with frequent vs. infrequent distractors. Bu...
Article
This study focuses on the ability of the adult sound system to reorganise as a result of experience. Participants were exposed to existing and novel syllables in either a listening task or a production task over the course of two days. On the third day, they named disyllabic pseudowords while their electroencephalogram was recorded. The first sylla...

Article
French participants learned English pseudowords either with the orthographic form displayed under the corresponding picture (Audio-Ortho) or without (Audio). In a naming task, pseudowords learned in the Audio-Ortho condition were produced faster and with fewer errors, providing a first piece of evidence that orthographic information facilitates the...
Article
This study examines the influence of orthography on the processing of reduced word forms. For this purpose, we compared the impact of phonological variation with the impact of spelling-sound consistency on the processing of words that may be produced with or without the vowel schwa. Participants learnt novel French words in which the vowel schwa wa...

Full-text available
Background: Event-related potentials (ERPs) are increasingly used in cognitive science. With their high temporal resolution, they offer a unique window into cognitive processes and their time course. In this paper, we focus on ERP experiments whose designs involve selecting participants and stimuli amongst many. Recently, Westfall et al. (2017) hi...
Article
Full-text available
The aim of this study is to contribute to a better understanding of cross-linguistic differences in the time course of determiner selection during language production. In Germanic languages, participants are slower at naming a picture using a determiner + noun utterance (die Katze ‘the cat’) when a superimposed distractor is of a different gender (...

Full-text available
The pronunciation of words is highly variable. This variation provides crucial information about the cognitive architecture of the language production system. This review summarizes key empirical findings about variation phenomena, integrating corpus, acoustic, articulatory, and chronometric data from phonetic and psycholinguistic studies. It exami...

Full-text available
In connected speech, many words are produced with a pronunciation that differs from the canonical form. How the speech recognition system deals with this variation is a fundamental issue in the language processing literature. The present study examines the roles of variant type, variant frequency, and context in the processing of French words with...

Article
Electrophysiological research using verbal response paradigms faces the problem of muscle artifacts that occur during speech production or in the period preceding articulation. In this context, this paper has two related aims. The first is to show how the nature of the first phoneme influences the alignment of the ERPs. The second is to further cha...
Article
The picture-word interference paradigm is often used to investigate the processes underlying word production. In this paradigm, participants name pictures while ignoring distractor words. The aim of this study is to investigate the processes underlying this task and how/when they differ from those involved in simple picture naming. It examines the...
Article
Full-text available
In the picture–word interference paradigm, participants name pictures while ignoring a distractor word. When targets and distractors share phonemic and/or graphemic content, naming latencies are shorter than when there is no overlap between the two words. This study examines the hypothesis that the facilitation effect is modulated by differences in...

Full-text available
This study investigates the processing and representation of words with multiple pronunciation variants in French. For example, the French word for horse can be produced with the vowel schwa (as in cheval) or without it (as in ch’val). Previous research has shown that variants with schwa (i.e., canonical variants) are processed faster and more accu...
Article
This study examined whether the brain operations involved during the processing of successive words in multi word noun phrase production take place sequentially or simultaneously. German speakers named pictures while ignoring a written distractor superimposed on the picture (picture-word interference paradigm) using the definite determiner and corr...
Article
This study examines the production of words the pronunciation of which depends on the phonological context. Participants produced adjective-noun phrases starting with the French determiner un. The pronunciation of this determiner requires a liaison consonant before vowels. Naming latencies and determiner acoustic durations were shorter when the adj...

Participants produced adjective-noun phrases starting with the French determiner un, whose pronunciation requires a liaison consonant before vowels. Naming latencies and determiner acoustic durations were shorter when the adjective and the noun both...
Article
The transformation of an abstract phonological code into articulation has been hypothesized to involve the retrieval of stored syllable-sized motor plans. Accordingly, gestural scores for frequently used syllables are retrieved from memory whereas gestural scores for novel and possibly low frequency syllables are assembled on-line. The present stud...

In the present study, we combine a novel-word learning task with visual-world eye tracking in order to investigate the influence of orthographic information on the phonological representation of reduced word forms in French.
Article
Full-text available
A major effort in cognitive neuroscience of language is to define the temporal and spatial characteristics of the core cognitive processes involved in word production. One approach consists in studying the effects of linguistic and pre-linguistic variables in picture naming tasks. So far, studies have analyzed event-related potentials (ERPs) during...
Article
Full-text available
Words are rarely produced in isolation. Yet, our understanding of multi-word production, and especially its time course, is still rather poor. In this research, we use event-related potentials to examine the production of multi-word noun phrases in the context of overt picture naming. We track the processing costs associated with the production of...
Article
Speakers usually produce words in connected speech. In such contexts, the form in which many words are uttered is influenced by the phonological properties of neighboring words. The current article examines the representations and processes underlying the production of phonologically constrained word form variations. For this purpose, we consider d...
Article
Hearing a reduced variant of a word seems to delay access to the representation of this word. One hypothesis explaining the precedence of full variants over reduced ones is that they correspond to the orthographic form of the word. In this study, we examined the role of orthography on the processing of variants resulting from schwa deletion in Fren...
Article
The present study investigated the role of spelling in phonological variant processing. Participants learned the auditory forms of potential reduced variants of novel French words (e.g., /plur/) and their associations with pictures of novel objects over 4 days. After the fourth day of training, the spelling of each novel word was presented once. Ha...
Article
This study examined the lexical representations and psycholinguistic mechanisms underlying the production and recognition of novel words with two pronunciation variants in French. Participants first learned novel schwa words (e.g., /ʃənyk/), which varied in their alternating status (i.e., whether these words were learned with one or two variants) a...

Full-text available
This study presents an analysis of over 4000 tokens of words produced as variants with and without schwa in a French corpus of radio-broadcasted speech. In order to determine which of the many variables mentioned in the literature influence variant choice, 17 predictors were tested in the same analysis. Only five of these variables appeared to cond...
Article
Full-text available
The present study investigated the lexical representations underlying the production of English schwa words. Two types of schwa words were compared: words with a schwa in poststress position (e.g., mackerel), whose schwa and reduced variants differ in a categorical way, and words with a schwa in prestress position (e.g., salami), whose variants dif...
Article
Full-text available
A categorical phonological process of deletion is traditionally assumed to account for the alternation of schwa with zero in French. This process is assumed to result in two discrete outputs: forms with schwa (i.e., schwa variants) and forms without schwa (i.e., non-schwa variants). However, the two studies we present here suggest a more complex pi...
Article
This study examines whether the production of words with two phonological variants involves single or multiple lexical phonological representations. Three production experiments investigated the roles of the relative frequencies of the two pronunciation variants of French words with schwa: the schwa variant (e.g., ) and the reduced variant (e.g., )...
Conference Paper
Full-text available
Clusters resulting from the deletion of schwa in French are compared with identical underlying clusters in words and pseudowords. Both manual and automatic acoustical comparisons suggest that clusters resulting from schwa deletion in French are highly similar to identical underlying clusters. Furthermore, cluster duration is not longer for clusters...
Article
Full-text available
Numerous factors have been advanced to account for the alternance of schwa with zero in French, such as lexical frequency, sonority, syllable structure, phonotactic constraints, etc. ... In the present study we use a recently developed statistical modeling technique, mixed effects models with crossed random effects, to capture the relative contribu...
Article
Full-text available
Three automatic alignment systems are compared in their adequacy to account for the vowel schwa as compared to a manual transcription obtained from two judges. Error rates and types are analysed, as well as the linguistic factors involved. The type of surrounding consonants and the duration of schwa influence the decisions of the three systems. Mor...
Conference Paper
Full-text available
This paper examines the nature of the process involved in optional schwa elision in French. More specifically, it aims at testing whether this process is gradual or categorical, on the basis of an analysis of the distribution of the duration of over 4000 schwas extracted from a large corpus of continuous speech. The distribution observed is bimodal...
Article
Full-text available
This paper presents an acoustic study on the phonetic properties of French schwa based on the analysis of a large corpus of radio broadcasted news. In order to address the question of whether the optional status of schwa correlates with a specific phonetic nature, optional French schwa is compared to its neighboring full front rounded vowels /2/ an...
Article
The present study examines the performance of an alignment system in the detection of schwas and the estimation of their duration. A comparison is made between the output of the system and a manual segmentation. Detection errors concern 8% of the data and estimation errors 22%. Regularities can be observed: the kind of errors and error rate are inf...

Project
The current project aims to examine how learning of novel names for familiar concepts is modulated by learning context (learning a word together with words from the same semantic category vs. different semantic categories).
Project
Run a meta-analysis to determine the size and standard error of the syllable frequency effect (shorter response latencies to high frequency than to low frequency syllables) in production tasks based on previously published and unpublished studies. If you happen to have data in which you compared the response latencies to high frequency and low frequency syllables in a production task, I would be happy to include them in the meta-analysis.
