This chapter provides a comprehensive overview of the structural foundations of language in the human brain, tracing the development of localization theories from phrenology to modern neuroimaging. It introduces key anatomical terminology and landmarks, including major brain regions, gyri, and sulci. The chapter explores the evolution of language localization theories, highlighting influential figures like Broca and Wernicke, and the shift from single-region to network-based models of language processing. It discusses various approaches to brain mapping, including macroanatomical, microanatomical (cytoarchitectonic), and functional definitions. The chapter also covers important anatomical pathways, particularly the dorsal and ventral streams for speech processing, while noting that these simplified models may not fully capture the complexity of language networks. The chapter concludes by acknowledging the challenges in precisely labeling brain regions and the complementary nature of different naming conventions, setting the stage for deeper exploration of language neuroscience in subsequent chapters.

This chapter highlights several aspects of human communication that rely on brain regions outside the traditional fronto-temporal language network. Factors affecting the neural resources needed for communication include the task demands (including acoustic or linguistic aspects), and abilities of individual listeners. When speech is acoustically challenging, as may happen due to background noise or hearing loss, listeners must engage cognitive resources compared to those needed for understanding clear speech. The additional cognitive demands of acoustic challenge are seen most obviously through activity in prefrontal cortex. During conversations, talkers need to plan the content of what they are saying, as well as when to say it – processes that engage the left middle frontal gyrus. And the cerebellum, frequently overlooked in traditional neurobiological models of language, exhibits responses to processing both words and sentences. The chapter ends by concluding that many aspects of human communication rely on parts of the brain outside traditional “language regions,” and that the processes engaged depend a great deal on the specific task required and who is completing it.

This chapter reviews the brain processes underlying human speech production, centered on the idea that a talker wants to communicate through to the execution of a motor plan. Cortical regions associated with motor control –including premotor cortex, supplemental motor area, and pre-supplemental motor area – are routinely implicated in speech planning and execution, complemented by the cerebellum. In addition to generating speech sound waves, speech production relies on somatosensory and auditory feedback, associated with additional regions of the superior temporal gyri and somatosensory cortex. A special point of emphasis is the contribution of the left inferior frontal gyrus (including the area traditionally defined as “Broca’s area”) to fluent speech production. Additional points include speech prosody and sensory-motor feedback. Finally, the chapter concludes by reviewing several common challenges to speech production, including dysarthria, apraxia of speech, and stuttering.

This chapter introduces the idea of language as a means to communicate ideas to other people. The speech chain – following the path of language from the mind of the speaker through to an acoustic signal, eventually interpreted by the mind of the listener – is introduced as an organizational framework. Of special note, all of the stages between talker and listener can influence the effectiveness of communication. The chapter provides a summary of central challenges associated with spoken language, including categorical perception, time-constrained understanding, flexibility, and multimodal integration. It then introduces several “big picture” themes from the book: stability versus flexibility, the importance of context, bottom-up versus top-down processing, hierarchical organization, the role of task demands, and neuroanatomical considerations related to localization and lateralization.

Building upon the previous themes, the book’s last chapter highlights the development of Spanish imperial cosmopolitanism, which enabled officials and subjects to make sense of and subsume the heterogeneous societies and regions they encountered and think of the world as one coherent unity. This cosmopolitanism was demarcated by imperial rivalries and officials’ self-perception as Catholic soldiers. Their actions and interactions with other people were read through the lenses of their Catholic identity, which also fostered a sense of Spanish exceptionalism. Moreover, most global interactions and imaginings occurred in areas usually deemed "peripheral," expressing the unity and coherence of the polity despite its dispersion and diversity.

Chapter 2 identifies and describes several methodological considerations in participatory research with adolescents, for example the issue of power sharing. Language is explored as a tool but also a potential barrier for engagement over time. Adolescents can have different roles and levels of involvement. The research setting and the characteristics of the research team are also explored.

This autobiographical fragment begins in a working-class high school and traces a career trajectory shaped by the world I grew up in and the world I entered. As a White woman from an American working-class background, I was an uneasy fit for the academy, circa 1979. I experienced obstacles and intellectual pleasures. I found many fascinating topics to study (e.g., class and cultural variation in early narrative) and many fascinating colleagues and students to work with. The outsider/insider position I occupied offered novel vantage points on the what, who, and how of developmental inquiry and on its telling omissions. My story of marginalization intersected with a historical moment when developmental psychology began to reckon with its narrowness and ethnocentrism. Thanks to the efforts of many developmental scholars, the field is now headed in a more context-sensitive and pluralistic direction while still contending with entrenched deficit discourses and other blind spots.

This chapter reviews changes to cognition with age. This includes sections on attention, executive function, motor control, and language. After reviewing cognitive aging and these basic cognitive functions, the chapter considers the burgeoning literature on training cognitive ability with age. This section includes review of intervention programs focused on physical activity, mediation and mediation, cognitive activities, working memory training, and long-term memory training.

In Khartoum the work of managing displacement and organising the future involved extensive educational projects. Residents of all socio-economic and ethnic backgrounds organised adult night schools and taught their own syllabuses of critical political and social education, using self-written alternative history textbooks, in multiple mother tongues or in a common southern Sudanese Arabic. Based on private archives of teaching resources, school records, aid agency archival marginalia, and personal accounts of educative work, this chapter reconstructs this intellectual terrain. It explores the definitions of education among these residents, which included practical and moral knowledge, linguistic creativity, and critical political analysis.

Chapter 6 returns to H. G. Wells to offer a fuller account of this writer’s longstanding fascination with animal experimentation, a practice he supported. Analysis of The Wonderful Visit (1895), The Island of Dr Moreau (1896), short stories, and essays reveal this author’s investment in contemporary scientific debates surrounding the thorny issues surrounding non-human pain introduced in Chapter 5. Despite differences in genre and tone, the selected texts each exploit the uneasy relationship between injury, experience, and expression to raise compelling questions about pain’s purpose and limits. The period’s vivisection debates were an important and productive context for Wells who capitalised on the ambivalence they produced, undermined the generic expectations of writings about the subject, and considered whether literary and linguistic methods could uniquely capture – or even solve – the problem of pain.
