Résumé/Abstract: It is well known that the statistical characteristics of a language, such as word frequency or the consistency of the relationships between orthography and phonology, influence literacy acquisition. Accordingly, linguistic databases play a central role by compiling quantitative and objective estimates about the principal variables that affect reading and writing acquisition. We describe a new set of web-accessible databases of French orthography whose main characteristic is that they are based on frequency analyses of words occurring in reading books used in the elementary school grades. Quantitative estimates were made for several infra-lexical variables (syllable, grapheme-to-phoneme mappings, bigrams) and lexical variables (lexical neighborhood, homophony and homography). These analyses should permit quantitative descriptions of the written language in beginning readers, the manipulation and control of variables based on objective data in empirical studies, and the development of instructional methods in keeping with the distributional characteristics of the orthography.

A new set of 299 pictures for Psycholinguistic Studies:
French norms for name agreement, image agreement, conceptual familiarity, visual complexity, image variability, age of acquisition, and naming latencies

Reference: Bonin, P., Peereman, R., Malardier, N., Méot, A., & Chalard, M. (2003). A new set of 299 pictures for psycholinguistic studies: French norms for name agreement, image agreement, conceptual familiarity, visual complexity, image variability, age of acquisition, and naming latencies. Behavior Research Methods, Instruments, & Computers, 35, 158-167.

Résumé/Abstract: Pictures are often used as stimuli in studies on perception, language and memory. As performance on different sets of pictures is generally contrasted, stimulus selection requires the use of standardized material to match pictures along various variables. Unfortunately, the number of standardized pictures available for empirical research is rather limited. The aim of the present study is to provide French normative data for a new set of 299 black-and-white drawings. Closely following Alario and Ferrand (1999), the pictures have been standardized on six variables: name agreement, image agreement, conceptual familiarity, visual complexity, image variability and age of acquisition. Objective frequency measures are also provided for the most common names associated with the pictures. Comparative analyses between our results and norms obtained in other similar studies are reported. Finally, naming latencies corresponding to the set of pictures were also collected from French native speakers and correlational/multiple regression analyses were performed on naming latencies. This new set of standardized pictures available from the Internet should be of great use to researchers when selecting pictorial stimuli.

Un correctif aux notations phonétiques de la base de données Lexique

Reference: Peereman, R., & Dufour, S. (2003). Un correctif aux notations phonétiques de la base de données Lexique. L’Année Psychologique, 103 , 103-108.

Résumé/Abstract: L'objectif de cette note est de présenter un correctif aux notations phonétiques accompagnant la base de données LEXIQUE récemment développée par New, Pallier, Ferrand, et Matos (2001). Les modifications concernent environ 18% de l'ensemble des entrées phonologiques de la base Lexique. Le fichier incluant les modifications est téléchargeable sur internet. / The LEXIQUE database has been recently developed by New, Pallier, Ferrand, and Matos (2001) to provide new frequency estimations of word usage. The database also includes additional information fields that can facilitate stimulus selection for psycholinguistic research in both visual and auditory word recognition. In particular, each orthographic entry is associated with a phonological transcription. However, due to several errors, the actual phonological codes seemed unworkable for stimulus selection or statistical analyses on the word corpus. The purpose of the present manuscript is to describe the corrective work that has been realised on the phonological codes. The computer file including the phonetic corrections can be downloaded on the web.

Vocolex. Une base de données lexicales sur les similarités phonologiques entre les mots français
VoColex: A lexical database on phonological similarity between French words

Reference: Dufour, S., Peereman, R., Pallier, C., & Radeau, M. (2002). Vocolex. Une base de données lexicales sur les similarités phonologiques entre les mots français. L’Année Psychologique, 102 , 725-746

Résumé/Abstract: L'étude psycholinguistique de la reconnaissance des mots parlés indique que les similarités phonologiques du mot avec d'autres mots de la langue influence son traitement. Nous décrivons une nouvelle base de données lexicales informatisée, VoCoLex, qui fournit un ensemble d'indicateurs statistiques sur les similarités entre mots de la langue française. Les similarités phonologiques sont estimées selon deux principes différent. Le premier tient compte de l'ordre séquentiel des phonèmes. Selon le second principe, les voisins phonologiques correspondent à tous les mots pouvant être dérivés par modification d'un phonème, quelle que soit sa position. Par exemple, VoCoLex fournit le nombre de voisins phonologiques par substitution d'un phonème, ou bien encore le nombre d'items partageant les mêmes 'n' premiers phonemes, en tenant compte ou non de la structure syllabique. Ces données permettent le contrôle ou la manipulation de diverses mesures de similarités, ainsi que des descriptions quantitatives du lexique parlé. // Several studies on auditory word recognition indicate that word processing is influenced by the phonological similarity with other words. We describe a lexical database, VoColex, which provides several statistical indexes of phonological similarity between French words. Phonological similarity is computed according to two distinct principles. According to the first principle, phonologically similar words share initial phonemes with the target word. According to the second principle, phonological neighbours correspond to any words which can be derived from the target by a single phoneme change (substitution, addition, or deletion) whatever the position of the modified phoneme. The statistical data provided by VoCoLex should allow the control and the empirical manipulation of various measures of phonological similarity, as well as quantitative descriptions of the auditory lexicon.

Lexop: A lexical database providing orthography-phonology statistics for French monosyllabic words.

Reference: Peereman, R., & Content, A. (1999). LEXOP: A lexical database providing orthography–phonology statistics for French monosyllabic words. Behavior Research Methods, Instruments, & Computers, 31, 376-379

Résumé/Abstract: During the last 20 years, psycholinguistic research has identified many variables that influence reading and spelling processes. We describe a new computerized lexical database, LEXOP, which provides quantitative descriptors about the relations between orthography and phonology for French monosyllabic words. Three main classes of variables are considered: consistency of print-to-sound and sound-to- print associations, frequency of orthography–phonology correspondences, and word neighborhood characteristics.
