This chapter begins by surveying the linguistic history of Ireland. Although it is situated on the periphery of the British Isles, there is evidence of contact between the island, other regions of Britain and indeed other countries in western Europe for centuries. It explores early and later contacts between the indigenised Celts and more recent colonisers and immigrants, including the Normans, the English, the Scots and twentieth-century settlers from the European Union prior to Brexit. These contacts have created a set of contemporary Irish English varieties that are not only distinctive with respect to other world Englishes but are also differentiated diatopically, ethnically and socially. Two main topics are addressed. The degree to which Irish English from different time frames is structurally similar to other dialects spoken elsewhere is considered alongside evaluating the extent to which contemporary Irish Englishes vary internally and externally with respect to their lexis, phonology, morphosyntax and discourse pragmatics. Some space is also devoted to examining how the study of Irish English has developed and what directions research might take in the twenty-first century in response to new approaches to modelling linguistic contact as well as the availability of larger and more diverse digital datasets.

In this chapter, we reinforce the book’s aim to shed light on changes inflicted on language, cognition, and the brain rather than to focus on advantages and disadvantages of being bilingual. To obtain a more realistic picture of bilingualism, its assets (i.e., what is easier), and its difficulties (i.e., what is taxing and leads to high consumption of mental resources), we have drawn on research from various disciplines. We conclude the book by identifying complexity as the major issue for research on bilingualism. The complexity problem is fundamental to definitions of bilingualism and the characterization of bilingual participants in empirical studies, leading to discussions about its assessment as a dichotomous or continuous variable. Considering bilingualism as an experience and how such experience impacts overall language development, cognition, and the brain at different levels are related to usage-based approaches of examining bilingualism as well as a concern regarding confounding and moderating variables. The shift for designing research in the field of bilingualism seems to necessarily be more interdisciplinary in nature than in the past.

Morocco melded its advanced regionalization initiative into a constitutional reform process launched to head off local Arab Spring protests. The literature has approached these reforms from a governance perspective. The initiative has enhanced the democratic legitimacy of regional councils and modestly increased their powers and resources, but without disturbing the state’s established administrative structure, wherein appointed governors shadow elected officials at every level. This chapter examines advanced regionalization with particular focus on its implications for the fate of Western Sahara. Internationally, Morocco has sold advanced regionalization as evidence that it remains committed to a political resolution based on its Autonomy Plan, which offered a special status of asymmetrical autonomy for Western Sahara in its constitutional order. The chapter argues that advanced regionalization instead underpins Morocco’s two-pronged strategy: a hardening external position on Western Sahara coupled with internal efforts to minoritize and folklorize Sahrawi identity. The goal of this strategy is to disassociate the question of Western Sahara from the decolonization/self-determination paradigm and reframe it as a matter of Sahrawi linguistic-minority rights and cultural preservation.

This chapter is a fictional account of several people talking about aspects of their lives that are impacted by variations in sex development at a support group meeting. In their exchanges about past, present and future medical encounters, the author draws out both the opportunities and the dilemmas presented by medicine. Through the characterizations, the author also teases out some of the most pertinent psychological themes in the field, such as how to decide about “normalizing” surgery for a child and how to talk about bodily differences in relationships. These themes are centralized in Chapters 9–14 and explored in the literature summaries and practice vignettes therein.

Chapter 6 summarizes the changes to medical care in recent years. There is now a greater recognition that the projected social and psychological challenges of genital variations cannot be fixed by surgery. The first international consensus statement on intersex was published in 2006. The statement makes a number of recommendations to improve care. Controversially however, a new term disorders of sex development (and, later, differences in sex development, or DSD) was introduced to replace intersex and hermaphroditism. Biotechnological developments have been advancing rapidly. More has been learned about “normal” and “abnormal” sex development. However, parents still struggle to talk to children about their bodily variations, young people still worry about getting into relationships, childhood genital surgery is still considered the only way out of stigmatization, psychological expertise is still a low priority in specialist services and the huge potential of peer support is not fully realized.

How to talk about variations in sex development is a major theme for impacted individuals and families. This is the topic of Chapter 12. The author summarizes the research literature with caretakers and with adults about the difficulties of disclosure. Considerable criticism has been levied at health professionals for failing to role model affirming communication. For sure there are gaps in health professionals’ talk, but the biggest contributor to the difficulties is to do with the widespread misunderstanding about the biological variations. Psychological care providers are not there to put a cheerful gloss over clients’ negative expressions. However, they can be part of the favorable social condition in which a wider range of meanings about bodily differences are negotiated. In the practice vignette, the author highlights how tentative and uncertain the enabling process is, where a negative view of sex variations is still widely endorsed in the social context.

In a gendered world, doctors and caretakers took for granted that making atypical bodies more typical was a humane way out of a difficult situation for child and family. Had the professionals carried out proper research, they would have learned from their young patients that the approach was physically and psychologically risky. But research on the long-term effects was not carried out, certainly not from the patients’ perspective. There was also no comparison group made up of people growing up with unaltered genital variations. Research with adults is the topic of Chapter 4 of this book. Since the 1990s, a number of outcome studies with adults have identified many problems of childhood surgery, such as multiple operations, scarring, shrinkage, sensitivity loss, unusual genital appearance and sexual difficulties.

Chapter 8 begins by pointing out the current lack of collective clarity about the role of psychological care providers (PCPs) and suggests that researchers and practitioners make collective effort to develop the role of PCPs in sex development in future. Meanwhile it outlines the psychological consultation process that is generic and familiar to most PCPs. The author provides an initial assessment template and summarizes the popular psychotherapeutic interventions. The template is visible in several of the practice vignettes in the ensuing chapters of the book. The author ends the chapter by arguing that the tertiary environment is set up for diagnostic workup and treatment and unsuitable for the kind of ongoing psychosocial input that is needed by individuals and families living in their communities. The author makes a case for PCPs in DSD centers to collaborate with peer support workers to enable nonspecialist providers in the community to contribute to ongoing support for individuals and families.

Chapter 2 begins with a brief summary of typical embryonic development of the urogenital and reproductive systems. Where the sex chromosomes, reproductive organs and the genitalia in combination do not fit the social categories of female and male, doctors and scientists used to call these physical outcomes hermaphroditism and intersex. They debated for a long time on the “true sex” of the individuals but could not agree on which of the biological sex characteristics should count as their true sex – should it be the sex chromosomes, the gonads or the genitals? Although in the age of genetics, much more is known about how the atypical features have developed. At the same time, people who are impacted by the variations are increasingly disputing medical framing of their differences. The twenty-first century was to seed a new and ongoing debate between the new medical term, differences in sex development (DSD) and intersex, which is now reclaimed by many impacted adults.

Chapter 11 of the book reviews potential psychological contributions in the highly charged process of assigning legal gender to a newborn with genital variations. Although a number of psychological theories exist for understanding gender development, it is the brain gender framework that has been singularly privileged in intersex and DSD medicine. However, the decades of research cannot contribute to the certainty professionals and caretakers seek. Psychological care providers (PCPs) have other frameworks to draw from in order to work ethically and pragmatically with families. In the practice vignette, the author envisions how a highly skilled PCP in a high-functioning DSD team could work substantially to help caretakers to cope with uncertainty and minimize the need for psychosocially motivated medical interventions. In the vignette, the psychological care path is in position before medical investigations begin. It remains highly active long after the medical and legal processes are completed. Although the vignette is built around a child diagnosed with 17β-hydroxysteroid dehydrogenase-3 deficiency, the care principles are relevant to legal binary gender assignment for children born with a range of sex development variations.

Difficulties with communication about bodily differences are strongly linked to sexual experiences. In Chapter 13, the author critiques the dominant ways of talking about sexuality in the wider society. These oppressive ideas can give rise to insecurities, self-objectification and body shame for people in general. Adults who have been medically managed are particularly vulnerable to the effects of objectification and shame. The author outlines typical components of sex therapy programs. However, rather than fix sexual problems, which can perpetuate people’s sense of inadequacy, the author suggests that psychological care providers support clients to process any trauma and develop a more relaxed and appreciative relationship with the body. This work, which requires generic therapy knowledge and skills, can be integrated with a range of specific sex therapy techniques and resources to reimagine a sexual future that focuses on bodily pleasure rather than gender performance. Although the practice vignette is built around a female couple, one of whom has partial androgen insensitivity syndrome, the care principles have wide applications for people with variations more generally.

Not all sex variations are apparent at birth. Sometimes they are internal and therefore not visible, that is, children are born looking like a typical boy or girl. The child may be brought to medical attention much later, for example when puberty does not follow the expected path. Many of these care users were not told the truth about their biological variation because adults believed that the information would harm them. At the same time, the care users also noticed that they were fascinating to health professionals, who may examine them in droves. Some of them did not discover the truth about their diagnosis and the treatment until mid-life.

For children whose external genitalia look different, when surgical safety and techniques improved, it became routine to align the urogenital anatomy of newborns and young children to the assigned gender. The gender-genitalia alignment was believed to be important psychologically for child and family. Because surgeons found it easier to feminize than masculinize the genitalia, most babies with genital variations were assigned female. From the 1990s, some of these adults have spoken out, talking of too many operations, been too often examined by too many and not understanding what was happening.

Inconsolable distress is neither a universal nor inevitable response to inability to have biological children. In Chapter 14, the author criticizes research with clinic samples that has produced a problem-saturated account of childlessness that obscures a wide range of alternative responses. The author examines the influence of pronatalist ideology on people who are impacted by infertility including many people with sex variations. Away from the treatment context, psychological input can guide individuals, couples and groups to explore personal meaning of nonparenthood. It can facilitate service users to grieve for what is not possible, challenge feelings of deviance and shame, reengage with a range of life goals and, perhaps most important of all, recast adult identities. Through the practice vignette built around a heterosexual couple, one of whom has a late diagnosis of Klinefelter syndrome, the author teases out the difficulties of working psychologically in a treatment context, where complex existential issues and relational dynamics are compressed into the frame of pressurized treatment decisions.

Chapter 9 tackles the theme of choosing “normalizing” interventions, which applies to children and adults with variations. It explores the limits of choice regarding invasive and irrevocable “normalizing” interventions in the field of sex development. It considers the role of emotion in decision-making and the complexities of obtaining informed consent. In the practice vignette, demand for surgery by a young person (with CAH) is a foregone conclusion – a familiar scenario in DSD services and one that places the psychological care provider (PCP) in an ambiguous position. The service user also has clear psychosocial care needs. She brings a unique suite of intersecting social circumstances that place demand on the PCP to be fluid and responsive to the dynamic and challenging referral context. The PCP in the vignette does not have the answers, but it is hoped that the story opens up conversations on the theme.

Psychological care is endorsed in DSD medicine. Psychosocial research has been on the increase. But these positive moves have not given psychological practice the kind of collective focus that is enjoyed by the biomedical disciplines. However, psychological care providers have a wide variety of thinking tools and practice techniques to draw on, if to work in an ad hoc way at times. These tools and techniques do not change, but some are more useful and relevant than others for this service context. In Chapter 7, the author discusses the strengths and weaknesses of key theoretical frameworks in healthcare psychology. A major weakness of the individualistic models is their lack of capacity to address structural inequalities in psychological wellness and distress. The author introduces aspects of the Power Threat Meaning Framework and describes how to draw from its theoretical richness to think systemically about what sex variations pose to individuals and families in the social context and how they are responded to. The Framework provides the theoretical backbone for some of the practice vignettes in the final section of the book (Chapters 9–14).

In the 1990s, some former patients mounted street protests in front of medical conferences to draw attention to their trauma. They reclaimed intersex as a personal identity and campaigned for healthcare reform. These developments are the focus of Chapter 5. Intersex is coming out of the closet more and more, through being a topic in television documentaries, novels, films and art. Intersex activists challenge medical authority to change practice. Furthermore, they are not waiting for doctors and scientists to come to their viewpoints. They have successfully lobbied human rights agencies to position childhood genital surgery as a violation of their human rights. They demand that surgery is delayed until the child can give informed consent or is at least old enough to participate in the discussion and offer their agreement.

In Chapter 10, the author suggests immense possibilities for psychological care providers (PCPs) to contribute to compassionate care following the birth of a child with variations (and in the antenatal period). Psychosocial research and first-person accounts inform us of caretakers’ brokenness, which is often responded to by “normalizing” the child. Here, the author suggests that PCPs work with caretakers in a grief-informed way. Grief is a language that everyone understands and compels services to privilege psychological safety as a first care principle. The practice vignette is built around an expectant mother in difficult circumstances with an unborn child with TS. However, the concept of grief is also relevant for older children and adolescents who are newly diagnosed. Indeed processing loss is integral to adjustment, whereby taken-for-granted ideas of selfhood give way to new identities.

This chapter introduces the book and its viewpoint that to understand language, we must adopt the same methodology successfully applied to other faculties of the human mind. To do so, we must recognize how minoritized languages – languages spoken by smaller populations, or languages that are not even official national languages – nonetheless have transformative effects on our understanding of the human language faculty.

This chapter summarizes the book overall, as well as mentioning case studies that were not covered in previous chapters. It concludes by reinforcing the importance of native speaker linguists and inclusiveness in the language sciences.
