“…Nowadays, EI programmes are based on theoretical foundations that highlight the importance of the context/environment and their relationship with the child (Tollan et al, 2023). Basically, six approaches can be identified: (1) the biopsychosocial model, developed by the World Health Organization (WHO, 2001), which seeks to integrate the child into his/her context as well as his/her autonomy; (2) the ecological-systemic model, which also seeks to normalise a child's situation and his/her continuing integration into his/her family and social context (Burger, 2014); (3) the transactional model, which also emphasises the interdependence of the child with his/her social context (Sameroff & Fiese, 2000); (4) Feuerstein's theory of structural cognitive modifiability (SCM) (Feuerstein & Jensen, 1980), focusing on a child's capacity for learning and maturation always within the mechanism of cultural transmission; (5) the activity-based approach (Bricker & Cripe, 1992), which proposes a global learning theory of the authors about developmental psychology and functional activities for a child's life; and (6) intervention programmes with a behavioural approach (Howlin et al, 2009), which are usually part of many of the elements of the previous programmes, but which have demonstrated their efficacy in a specific way, such as Applied Behaviour Analysis (ABA), Early Intensive Behaviour Intervention (EIBI), Treatment and Education of Children with Autism and Associated Communication Problems (TEACCH), the DENVER model , which involves intensive communication training, cognitive-behavioural therapy, and parent training, or the LOVAAS programme, which proposes a comprehensive and highly-structured training of functional and life-relevant behaviours for the child.…”
