Chapter Summary

The second edition has sixteen chapters in two parts, running to about 650 numbered pages (the publisher gives 704 including front and back matter). Part I, "Key Concepts in Language Production, Comprehension, and Acquisition", has twelve chapters; Part II, "Language Disorders", has four. Each chapter ends with a "Summary and Conclusions" and a "Test Yourself" list of review questions. The publisher describes the book as multidisciplinary, drawing on psychology, linguistics, philosophy, computer science, neurology and neurophysiology, and as describing the experimental evidence behind the major theories.

Chapter 1: An Introduction to Language Science

The chapter opens with the study of the Pirahã language by Dan Everett and uses it to pose the field's large questions: what it means to know a language, how languages work and where they come from. It covers the characteristics that distinguish language from other communication systems (including semanticity, arbitrariness, discreteness, displacement, generativity and duality of patterning), grammar, research on communication in apes, the continuity and discontinuity views of language origins, and the relation between language and thought, from Whorf's linguistic determinism to the revival of linguistic relativity. It ends with a first description of the language-processing system.

Chapters 2–3: Speech Production and Comprehension; Word Processing

Chapter 2 treats speech production through speech errors, tip-of-the-tongue states, picture-naming studies and the spreading activation model, then articulation and speech perception, including coarticulation, the motor theory, the McGurk effect, mirror neurons and general auditory approaches. Chapter 3 moves to words: how word form is mentally represented, lexical semantics (including associationist and embodied accounts), lexical access across three generations of models, lexical ambiguity resolution and the neural basis of lexical representation.

Chapters 4–6: Sentence Processing; Discourse Processing; Reference

Chapter 4 concerns parsing: two-stage models and constraint-based models, the argument structure hypothesis, alternatives such as construal and good-enough parsing, and long-distance dependencies. Chapter 5 covers discourse: construction-integration theory, the structure-building framework, the event-indexing model, situation models, inferencing, and the neural basis of discourse comprehension. Chapter 6 deals with reference and co-reference, binding theory and psycholinguistic theories of anaphora such as the memory focus model and centering theory.

Chapters 7–8: Nonliteral Language Processing; Dialogue

Chapter 7 considers the standard pragmatic view, metaphor and its competing accounts, metonymy, idioms, embodiment and the neural basis of nonliteral interpretation. Chapter 8 covers Gricean maxims, the interactive nature of dialogue, common ground, audience design and the effects of listeners' perspective-taking.

Chapters 9–10: Language Development in Infancy and Early Childhood; Reading

Chapter 9 follows acquisition from prenatal learning and infant perception of phonemes through the segmentation problem and statistical learning to word meanings and the acquisition of morphology and syntax. Chapter 10 addresses reading: eye-movement control, models such as E-Z Reader, writing systems, learning to read, visual word recognition models and dyslexia.

Chapters 11–12: Bilingual Language Processing; Sign Language

Chapter 11 considers the simultaneous activity of two languages, competition in production, models of language control such as BIA+, bilingualism and executive control, individual differences in second-language learning and the neural bases of bilingualism. Chapter 12 describes the characteristics of signed languages, lexical access and acquisition, the neural basis of sign language, the effects of deafness on cognition and cochlear implants.

Chapter 13: Aphasia

The first of the disorders chapters covers what happens to language when the brain is damaged, the classic Wernicke-Lichtheim-Geschwind model and its problems, hypotheses about syntactic parsing in Broca's and Wernicke's aphasia, and treatment and recovery.

Chapters 14–16: Developmental Language Disorder; Language and Autism; Language Dysfunction and Schizophrenia

Chapter 14 covers identifying and explaining developmental language disorder and its treatment options. Chapter 15 treats language in autism, from diagnosis and language profiles to proposed neural and cognitive explanations and the evidence for and against various treatments. Chapter 16 addresses language deficits in schizophrenia, including the proposed neural abnormalities, failures of semantic memory and working memory, theory of mind, auditory hallucinations and delusions. The publisher identifies the autism and schizophrenia chapters, and the section on disorders, as new in this edition.

Key Concepts

Chapters 1–3: Language Science, Speech and Words

• Design features of language: properties such as arbitrariness, displacement and generativity that separate language from other communication systems.
• Linguistic relativity: the idea, associated with Whorf, that the language one speaks shapes thought.
• Spreading activation and lemma theory: a model of how words are retrieved for speech.
• Lexical access: the process of recognising words, treated through first-, second- and third-generation models.

Chapters 4–8: Sentences, Discourse and Interaction

• Constraint-based parsing: the view that many information sources influence sentence interpretation from the start, contrasted with two-stage models.
• Situation model: a mental representation of the events a discourse describes.
• Anaphora and binding theory: how pronouns and other expressions are linked to referents.
• Common ground and audience design: the shared knowledge and perspective-taking in conversation.

Chapters 9–12: Development, Reading, Bilingualism and Sign

• Statistical learning and segmentation: infants' use of patterns in speech to find word boundaries.
• Dual-route and single-route models: competing accounts of word reading.
• Bilingual language control: how speakers manage two active languages.
• Sign language lateralisation: the neural basis of signed language.

Chapters 13–16: Language Disorders

• Aphasia: language impairment after brain damage, with competing accounts of syntactic deficits.
• Developmental language disorder: persistent language impairment in children, with several explanatory accounts.
• Theory of mind and weak central coherence: cognitive accounts of autism.
• Language deficits in schizophrenia: disruptions of semantic memory, working memory and self-monitoring.

Critical Analysis

Strengths

• Evidence-centred. The publisher stresses in-depth descriptions of the experimental evidence behind theories, and the contents show competing models set side by side in nearly every chapter, from first- to third-generation lexical access models to two-stage and constraint-based parsing and to dual- and single-route reading models.
• Wide scope. The book covers speech, words, sentences, discourse, nonliteral language, dialogue, acquisition, reading, bilingualism and sign language, and then four disorder chapters.
• Consistent study apparatus. Each chapter has a summary and a "Test Yourself" set, and Chapter 1 adds "Think About It" questions. The publisher also lists learning objectives, thought exercises and a companion website with quizzes and slides.
• Updated for the second edition. New coverage of language acquisition, cognitive neuroscience of language, bilingualism and sign language, plus the new disorders section with two entirely new chapters, are listed by the publisher.

Limitations

• Length and density. The book runs to roughly 650 pages and 16 chapters; a single semester must select among them. Several chapters (for example speech perception, lexical access and parsing) are organised around model-by-model comparisons, which may be demanding for a student new to the area.
• Acquisition is compressed. Child language development gets one chapter (Chapter 9), centred on infancy and early childhood, so a course focused on acquisition will need a dedicated book.
• Broad disorder chapters. The autism chapter ranges widely over diagnosis, causes and treatments, including sections on ineffective or harmful treatments, which goes beyond language processing and may be more than a general psycholinguistics course needs.

Where It Fits in the Course

Traxler's book is a research-based general textbook that covers typical language processing and, in Part II, language disorders. Paul Warren's Introducing Psycholinguistics is a shorter introduction for students new to the field, with summaries, exercises and suggestions for further reading, and is a gentler first read. Julie Sedivy's Language in Mind is a comprehensive survey of language processing, acquisition and the relation of language to cognition, in a similar territory. Trevor Harley's The Psychology of Language: From Data to Theory is a research-led account that sets experimental findings against competing models at every level, treats development, bilingualism and language disorders alongside adult processing, and expects a prior course in psycholinguistics or cognitive psychology.

For acquisition, William O'Grady's How Children Learn Language is a concise, non-technical account and Eve Clark's First Language Acquisition is a graduate-level textbook taking a usage-based view; either supplements Traxler's single acquisition chapter.

How to Use This Book

The book is meant for upper-level undergraduates in psycholinguistics, language processing and communication disorders, and for students in psychology, linguistics, cognitive science, neuroscience, language education and computational linguistics. An introductory course in linguistics or psychology is helpful; no advanced statistics or neuroscience is required.

A practical plan: read Chapter 1 for orientation, then Chapters 2 to 6 as the core of adult language processing, in order, since word, sentence and discourse processing build on one another. Choose among Chapters 7 to 12 according to the course: nonliteral language and dialogue for pragmatics, Chapter 9 for acquisition, Chapter 10 for reading, Chapters 11 and 12 for bilingualism and sign language. Part II can be taken as a unit for a course on communication disorders, or one chapter at a time to illustrate a theory from Part I; the aphasia chapter pairs well with Chapter 4 on parsing.

Use the "Test Yourself" questions to check recall and the thought exercises for discussion, and the companion website for quizzes. Because the book discusses competing models, keep a short table of each model's claims and the evidence for and against it.
