This book updates and expands on Relational Competence Theory developed originally by Dr. Luciano L'Abate since 1976. Over the years, this theory has received various updates and expansions, especially after being produced according to a hierarchical flowchart, as common in most complex human organisations. The present book concentrates particularly on a condition called Alexithymia, similar but not the same as the Asperger Syndrome, the inability to experience feelings and to express them as emotions. Most chapters in this book expand on the first model of RCT about how feelings are experienced and expressed using an expanded revision of the Relational Answers Questionnaire. Self-presentation was evaluated with a new scale, and Selfhood was expanded with a widely revised and expanded Self-Other Profile Chart.
