This article was originally published with an incorrect author affiliation. The first affiliation of Florence Baills was given as Universitat de Lleida, IfL-Phonetik, University of Cologne, Spain. This should have read Universitat de Lleida, Spain. This has now been corrected and the PDF and HTML updated.
Additionally, the phrase ‘Turn: movements of the head’ on page 11 should have read ‘Turn: Leftward and rightward movements of the head’.
The publisher apologises for these errors.
