  ## Research
  
  In 2011 Towards an Understanding of Language Learner Self-Concept was published by Springer Publishing. In this book, Mercer investigates the nature and development of language and learner self-concept. The book provides a deep insights into how learners view themselves, and how these self-beliefs can develop and affect the progress of an individual's language learning process.
  
  In her most-cited journal article entitled Language learner self-concept: Complexity, continuity and change, published in System in 2011, Mercer investigated the nature and dynamics of self-concept in language learning. She found that self-concept is perhaps best conceived of as a complex, multilayered, multidimensional network of interrelated self-beliefs.
