### **Miguel P ´erez Pereira**

Miguel Perez Pereira is an emeritus professor of Developmental and Educational Psychology at ´ the University of Santiago de Compostela. My fundamental field of research has been Evolutionary Psychology, and more specifically the study of Language Development. I have researched on language development in Spanish-speaking or Galician-speaking children.

I have been the main researcher of several projects and contracts related to research on blind children, from which several publications in impact journals have been derived. Since 1998, I have developed several projects to elaborate the Galician version of the MacArthur-Bates scales (CDI). Such research has resulted not only in the construction of the scales, but also in obtaining a significant amount of data on the acquisition of language in Galician children. Since 2008, we have started a longitudinal project on language acquisition in preterm infants. Multiple publications in impact journals have been derived from these investigations, and it is the main topic of my research at present.

I have been the first President of the Official College of Psychologists (COP) in Galicia, and a member of the first Governing Boards of the COP in Spain. I have also been the founder and first President of the Association for the Study of Language Acquisition (AEAL), and I have had a very active participation in the International Association for the Study of Child Language (IASCL) of which I have been a member of the Committee Executive, and President of the Electoral Committee (2005).

I have been Associate Editor of Journal for the Study of Education and Development, and currently (since 2018) I am of the Revista de Logopedia, Foniatr´ıa y Audiolog´ıa, and I belong to the Editorial Board of several journals (First Language...).

### **Daniel Adrover-Roig**

Daniel Adrover-Roig holds Ph.D. in Psychology from the University of the Balearic Islands (UIB) where he currently works as an associate professor (Department of Applied Pedagogy and Psychology of Education).

I have been a lecturer and researcher at several universities (Universitat Oberta de Catalunya). My pre-doctoral stays were carried out at the Universitat W ¨ urzburg, Germany; Department of ¨ Experimental Psychology, Oxford University, United Kingdom. After conducting my Ph.D. on age-related behavioral and neural correlates I did a 2-year post-doctoral research stay at the Centre de Recherche de l'Institut Universitaire de Geriatrie de Montr ´ eal (Canada), focusing my studies on ´ the associations of bilingualism with higher-order cognitive functions. Since 2011, my teaching has been centered on Developmental Psychology in School Age and Language Disorders in Primary Education. I have also been Vice-Dean of the Faculty of Education. I am privileged to head the Research Group in Development, Education, and Language (I+DEL). My research interests involve studying how bilingualism influences human cognition, with a particular interest in children with language difficulties, healthy adults, and older adults without cognitive impairment. In recent years, I have also been exploring the phenomenon of bullying and its relationship to educational needs and language difficulties, in particular, Developmental Language Disorder (DLD). I have supervised several doctoral theses on these topics and have been the principal investigator of two consecutive projects funded by the Ministry of Science and Innovation. Thanks to ongoing teamwork, I have been able to publish about 35 articles indexed in the Journal of Citation Reports (JCR) database and over 30 books and book chapters. I have also participated in more than 100 national and international conferences. Our research group was awarded the "Jordi Perello" prize in research ´ in Speech Therapy from the College of Speech Therapists of Catalonia, and in January 2022 the "La Caixa" Foundation awarded us a Flash Call in Social Sciences, with which we are expanding existing research on cyberbullying.
