“Studies” are mostly viewed as the results of research in scientific work and are always preceded by numerous extensive research projects.
The evolution of the method according to the principles of Professor Tomatis can so far be divided into ten major periods.
I - Les Mélanges. 1952 - 1972
Structure of the fundamental basic studies of Prof. Tomatis, bundled in the edition “Les Mélanges” ["The Mixes"].
1. Incidences observées dans les lésions auriculaires constatées chez le personnel des bancs d’essai et les professionnels de la voix - Bulletin du Centre d’Etudes et de Recherches médicales of the SFECMAS (Nord-Aviation) - September 1952. [Incidences observed in lesions of the ear, observed in test bench personnel and voice professionals].
2. L’oreille musicale—Le bégaiement, essais de recherche sur sa pathogénie—L’Oreille Directrice—L’audiométrie dynamique—L’audiométrie d’usine—Recherches sur la pathogénie du bégaiement—Correction de la voix chantée” - 1953. [The musical ear -- Stuttering, research trials on its pathogenesis -- The Dominant Ear -- Dynamic audiometry -- Workplace audiometry -- Research on the pathogenesis of stuttering -- Correction of the singing voice - 1953]
3. Information sur la surdité professionnelle—La sélectivité auditive – 1954.
[Information on Occupational Deafness — Hearing Selectivity - 1954]
4. L’effet TOMATIS [The Tomatis Effect] - The relationship between phonation and hearing, as well as the possibility of correcting both of these essential functions - Professeur Louis Longchambon
5. Modifications phonatoires d’origine auditive et applications physiologiques et cliniques: Académie Nationale De Médecine - M.Raoul Husson - 4 Juin 1957.
[Phonatory modifications of auditory origin, and physiological and clinical applications]
6. Les Mélanges [The Mixes] A collection of multiple studies, reports and investigations – 1952 – 1972.
II - University of Potchefstroom, South Africa
Research carried out in collaboration with the University of Potchefstroom.
Publications of Prof. Jaarsveld and Prof. Du Plessis about stuttering problems.
III - University of Toronto, Canada
Research conducted in collaboration with the University of Toronto in Canada. Meta-analysis: Tim Gilmor.
IV - Tomatis News
Research conducted in collaboration with the then existing centers, published in “Tomatis News” - 1980 – 1994.
The documents from studies I to IV are housed in the Museum of Professor Alfred Tomatis, at Mozart Brain Lab, Stationsstraat 36, 3800 Sint-Truiden, Belgium. The studies are supported by 44,000 personal documents from the professor and his research team.
V - Schools
1. Euskirchen, Germany
Research conducted by Jozef Vervoort in the Belgian Primary School of Euskirchen, Germany (1974 - 1975 school year). Children aged 5 were tested and compared between two similar primary schools - at the beginning and end of the experiment. Standard age-appropriate tests (Van Bever, Grosjean and Groven) were performed for fine motor skills, coordination, visual motor skills, and lateralization. The therapy was implemented in the classroom; great improvement was observed in children who received stimulation for one hour a day.
The study was printed in “Kindergarten Magazine”, a publication for Kindergartens, by the Belgian Ministry of Education
2. Europaschool, Genk, Belgium
Research under the supervision of Jozef Vervoort at a Primary School in Genk (Belgium).
3. "Attention! The Way to Success”, Poland
VI - University La Sapienza, Rome, Italy
Research in cooperation with Dr. Carmela Stillitano from the University “La Sapienza” in Rome:
1. "From the Ear to the Voice and Color”: This wonderful study shows how a scotoma at 2,000 Hz in both air and bone conduction causes poor voice control. Professor Tomatis' "listening test" and a voice analysis using the "Talk" software, were done before and after the therapy. The measured energy levels from the "evoked potentials", also receives special attention here. Furthermore, this study contains a wonderful analysis of drawings, both in terms of shape and color, in relation with the special stimulation and with the pieces of music used. Published in book format by Mozart Brain Lab, Belgium.
2. "The Effects of the Tomatis method on the Artistic Voice” - “International Journal of Listening” by Rouledge—Taylor and Francis Group - 27 July 2016.
This study, inspired by the previous study, provides a clear picture of the positive impact of the method on the voice of singers.
3. “The Effects of the Tomatis Method on Tinnitus”
Stillitano, C. Fioretti, A. Cantagallo, M. Eibenstein, A. Tinnitus Center, European Hospital, Rome, Italy - Mozart Brain Lab, Sint-Truiden, Belgium.
A remarkable study on the positive effect of auditory brain stimulation on tinnitus.
VII - "Quantitative Effects of Auditory Stimulation according to the Tomatis Method. A Preliminary Study of the Correlation between the Tomatis Listening Test and Auditory Cognitive Evoked Potentials”.
Marine de Vandeul (MD), Jozef Vervoort, Jacques Grapperon, Tantely Razfimahéfa, Jean Vion-Dury. https://hal.archives-ouvertes.fr/hal-02311520/document
Submitted Oct. 11, 2019.
In this experiment, clearly measurable results were observed both in listening tests and auditory evoked potentials, as well as in response time, in children treated with Audio Psycho Phonology compared to children who did not receive the treatment.
VIII - "Der Audio-Psycho-Phonologische Ansatz nach Tomatis bei der Behandlung von Kindern mit Aufmerksamkeitsstörungen”
“Empirische Sonderpädagogik 2019 (Nr. 1, S.81 – 92)
["The Tomatis Audio-Psycho-Phonological Approach to the Treatment of Children with Attention Disorders” - Empirical special education 2019]
Professor Wolfgang Beelmann and Mareike Kopka - “University of Applied Science”, Bielefeld, in cooperation with Jozef and Astrid Vervoort, MBL.
This study focuses mainly on the positive influence of the method on children with ADHD.
IX - “The Improvement of Severe Psychomotor and Neurological Dysfunctions Treated with the Tomatis Audio Psycho Phonology Method Measured with EEG Brain Map and Auditory Evoked Potentials”
Journal of Neurotherapy, Vol. 11 (4) 2007- Jozef Vervoort, M.J.A.de Voigt en W. Van den Bergh MD.
The study provides wonderful evidence that this therapy method can achieve clearly demonstrable psychological and neurological improvement in children with very severe disorders.
X - “Neural circuits underlying mother’s voice perception predict social communication abilities in children”
Daniel A. Abrams, Tianwen Chen, Paola Odriozola, Katherine M. Cheng, Amanda E. Baker, Aarthi Padmanabhan, Srikanth Ryali, John Kochalka, Carl Feinstein, and Vinod Menon - 16 May 2016 https://doi.org/10.1073/pnas.1602948113
From the point of view of Professor Tomatis' method and work, as well as from our own work, this wonderful study is the most compelling evidence that even meaningless words spoken by the mother activate various areas of the child's brain, including the areas of reward, emotion and facial recognition. This is evidence of the extent of the propagation of the mother's voice in the child's brain.
Most importantly, this activity provides a neural fingerprint for the child's social communication skills.
