Notes on Reading vs Spoken Language: Processes, Research Methods, and Phonology

Overview

  • Lecture comparing reading and spoken language to build understanding of reading processes and speech perception later in the course.

  • Goal: understand what reading is, how it’s investigated in research, and the terminology used in reading research.

  • Emphasis on bridging reading and spoken language concepts so competent language users understand both modalities, regardless of whether information is heard or read.

  • Preview: you’ll learn why reading research often treats reading and speaking as separate components and how they can be integrated.

Reading vs Spoken Language: Similarities and Differences

  • Similar core message: competent adults understand messages in both modalities (written vs spoken).

  • Key differences highlighted:

    • Word boundaries: written text clearly separates words (spaces); spoken language lacks explicit word boundaries due to continuous speech.

    • Co articulation and speaker variability: reading uses your internal representation of words; spoken language involves pronunciation differences across speakers and coarticulation effects.

    • Memory load: reading reduces memory load because the words remain on the page/screen; spoken language requires holding information in working memory as it’s heard.

    • Punctuation vs prosody: punctuation guides reading and interpretation in writing; prosody (pitch, stress, intonation) guides interpretation in speech.

    • Absence of speech-reading cues in reading: you don’t have facial expressions or voice tone to infer meaning from text, unlike listening to speech.

    • Developmental and age-related differences: reading and spoken language abilities develop differently; reading ability often depends on prior spoken language skills.

  • Practical implication: while there are shared processing components, researchers often separate reading and spoken language for clarity, then later integrate them.

Terminology: Orthography vs Phonology

  • Orthography: the letters on the page or screen; the visual representation of language (graphemes).

  • Phonology: the sounds of language; phonemes are the individual sounds.

  • Relationship: a mapping exists between orthography (letters) and phonology (sounds), but English has not a strict one-to-one correspondence; some letters or letter combinations map to multiple sounds.

  • Alphabet and sound mapping:

    • English features many irregularities: gh can be silent or pronounced differently; o u g h has 6–8 possible pronunciations depending on context.

    • Examples discussed: a can sound like /a/ as in "cat" vs /æ/ in some dialects; oo can be /uː/ as in "soon" or /ʊ/ in other contexts; ck typically /k/; gh can be silent or /f/ in some words; ch can be /tʃ/ as in "chair"; and various mismatches like A sometimes sounding like R in certain spellings.

  • Phoneme awareness (phonemic awareness): schooling to map sounds to letters, starting with simple words (e.g., cat → /k/ /æ/ /t/), then rhymes (fat, sat, bat) and invented words (e.g., blat).

  • Key teaching point: in English, some sounds have close letter-sound mappings, while others do not; learners are taught to map sounds to letters through explicit instruction.

Reading vs Language Development: Language Learning and Access to Curriculum

  • Reading leverages spoken language as a gateway to literacy.

  • Access to the curriculum is often via reading; reading ability builds on prior spoken language skills.

  • Variation in learning trajectories: individuals’ reading ability is largely predicated by their spoken language proficiency.

How Reading is Studied: Approaches and Methodologies

  • The literature often uses five main approaches to probe reading processes:
    1) Lexical decision tasks: decide quickly whether a string of letters is a real word or not (real words vs non-words).
    2) Naming tasks: read words aloud to examine pronunciation and access to phonology.
    3) Eye-tracking: monitor where and for how long readers fixate; reveals processing difficulty and how much backtracking occurs to re-check words.
    4) Priming studies: present a prime word before a target word; primes can be related in spelling, meaning, or sound to influence processing.
    5) Neuroimaging/electrophysiology: cap-and-electrodes to measure brain activity during reading; focus on components like N400 and P600.

  • Brain measures:

    • N400: negative deflection ~400extms400 ext{ ms} after a word is encountered, linked to semantic processing.

    • P600: positive deflection ~600extms600 ext{ ms} after word perception, linked to syntactic/structural processing.

Literacy Education, Phonology, and Phonological Awareness

  • Phonology (sound system) overview:

    • New Zealand English has roughly 44extor4544 ext{ or } 45 phonemes, typically 2525 consonants and 2020 vowels.

    • IPA (International Phonetic Alphabet) catalogs all possible sounds; sounds mapped by place of articulation, voicing, and manner (stop, fricative, etc.).

  • The video on NZ English emphasizes that the spoken inventory is larger than the 26 letters of the alphabet; multiple letters or letter combinations map to a single sound.

  • Phonological awareness in early reading:

    • Children learn to segment words into phonemes and understand correspondences between sounds and spellings.

    • The progression: learn simple words → build phoneme awareness → read more complex words (catapult, catastrophe) by combining phonemes.

  • Phonics vs other approaches:

    • Phonics emphasizes explicit letter-sound mappings; historically, it’s been linked to faster initial decoding but can be overly prescriptive and memory-heavy if overemphasized.

    • A balanced view recognizes the role of phonology in reading across the lifespan, including adult reading, and the importance of keeping meaning central to reading.

  • Reading development and research context:

    • There is a critical program in New Zealand (Better Start Literacy Project) that emphasizes explicit foundational skills for reading to support later reading-to-learn.

    • The shift in education: from learning to read (early years) to reading to learn (later schooling), usually around age 898–9 years.

  • Inner speech in reading:

    • Many readers report a form of inner speech (auditory imagery) during silent reading; evidence suggests phonological processing is engaged even when reading silently.

    • A notable study using limericks showed phonology is engaged in silent reading and is affected by regional accents (e.g., Bath vs path pronunciations) and by tongue-twister complexity.

  • Silently reading and phonology across accents:

    • A limerick study compared readers from the North of England vs the South; differences in rhyming pronunciation influenced eye movements, indicating phonology is accessed during silent reading.

    • Tongue twisters cause more fixations and longer processing times during silent reading, indicating phonology involvement even without vocalization.

  • Phonological neighbors and priming in reading:

    • Phonological neighbors: words that differ by one phoneme (e.g., gate with neighbors bait, got, get).

    • Experiments show processing is influenced by neighbors and their similarity; if a neighbor is a word and shares phonology, reading can be more difficult in some conditions (e.g., CLIP vs KLIP example).

    • Phonological priming speeds up reading when primes align with expected phonology, suggesting phonology facilitates early decoding and word recognition.

  • Homophones and phonological processing:

    • Studies show more errors or slower responses when target words have phonological neighbors that sound alike (e.g., rows/rose) than when they don’t.

    • In reading sentences, phonology can influence processing even when spelling differs (e.g., “made” vs “maid” in a sentence) as readers’ brains detect phonological similarity.

  • Phonology in deaf readers:

    • Even profoundly deaf readers engage phonological processing during reading, suggesting phonology-like representations may be internalized through alternative modalities (e.g., lip-reading, sign language) or auditory-imagery analogs.

  • Implications for research and theory:

    • The data collectively suggest phonology plays a central role in reading across modalities and populations, not just in early literacy but also in skilled adult reading.

The International Phonetic Alphabet (IPA) and Speech Sounds

  • The purpose of IPA: a universal chart showing how to pronounce sounds across languages, organized by place and manner of articulation.

  • Relationship to reading: understanding phonemes helps with decoding and spelling; reading instruction often uses phonetic awareness to map sounds to letters.

  • Place, voicing, and manner dimensions:

    • Place: where in the mouth or vocal tract the sound is produced (labial, dental, alveolar, etc.).

    • Voicing: whether the vocal cords vibrate (voiced) or not (voiceless) when producing a sound (e.g., /p/ vs /b/).

    • Manner: how air is constricted (stop, fricative, etc.).

  • Important phoneme examples for teaching:

    • P vs B: voiceless vs voiced stops; feel v. sound with a finger on the throat.

    • T vs D; K vs G; distinction between voiceless and voiced counterparts.

  • Practical takeaways for learners:

    • Understanding phoneme production helps in decoding difficult spellings and in phonological awareness tasks.

    • Dialect and accent variations alter phoneme realizations, which can affect reading strategies.

The Wacky Reading Demonstration and What It Teaches

  • A widely circulated example shows that people can read text with jumbled interior letters as long as first and last letters are in place.

  • Important caveat: this claim is not a reliable scientific citation to Cambridge University; it’s a popular anecdote with questionable provenance.

  • Takeaway for reading research:

    • Word recognition relies on both holistic shape/letter patterns and sub-lexical (phonological) processing; readers often use a combination of cues, not just letter-by-letter decoding.

  • Caution in interpretation: avoid overgeneralizing from a single demonstration; research shows multiple routes to word recognition depending on context and reader experience.

Phonology in Reading: Experimental Evidence and Insights

  • Inner speech in reading:

    • Many adult readers access their phonology when reading, even silently; eye-tracking and self-reports indicate phonological processing during silent reading.

  • Accent and regional variation studies:

    • North vs South England differences (Bath vs path) influence how readers process rhymes and verse; this reveals that readers implicitly simulate phonology during reading.

  • Tongue twisters and silent reading:

    • Silent reading of tongue twisters leads to more errors and slower reading, suggesting phonological processes are engaged even without vocalization.

  • Phonological neighbors and reading difficulty:

    • When a target word has a highly similar phonological neighbor that is a real word, processing can slow down due to competition at the phonological level.

    • If the neighbor is not a real word, processing can be eased, indicating that lexical status of neighbors matters.

  • Phonological priming in reading:

    • Primes related by phonology can speed up recognition of subsequent words, highlighting the speed and automaticity of phonological activation during reading.

  • The role of phonology for reading speed and comprehension:

    • Evidence suggests phonological processing speeds up reading when consistent with expectations, and may be essential for efficient reading, not just a byproduct.

  • Deaf readers and phonology:

    • Even individuals with profound hearing loss show evidence of phonological processing in reading, indicating robust phonology-like representations beyond acoustic hearing.

Reading Education: Foundations, Phonology, and Foundations of Literacy

  • Phonological awareness as foundational skill:

    • Explicit teaching of sounds and their relationship to letters supports decoding and spelling.

  • Better Start Literacy Project (University of Canterbury context):

    • A funded program focusing on foundational literacy development to improve later reading outcomes.

  • From learning to read to reading to learn:

    • Early years emphasize decoding; around ages 898–9, students transition to reading for understanding, learning from texts across subjects.

  • Phonics: historical and modern views:

    • Phonics-to-decode approach emphasizes letter-sound correspondences but can be memory-intensive if misapplied; recent perspectives advocate a balanced approach integrating decoding with meaning-making and prior linguistic knowledge.

  • The cognitive steps in reading development (how decoding becomes reading for meaning):

    • Phoneme identification and phonological storage in the mental lexicon.

    • Decoding (sounding out) words to access their meanings.

    • Encoding, retrieval, and lexical access as part of reading aloud.

    • Greater integration as vocabulary and syntax knowledge improve.

The Role of Phonology in Adult Reading and Silent Reading

  • Inner speech: many readers report hearing inner voices while reading; experiments show internal phonological activation supports comprehension.

  • Practical implications for reading instruction and literacy assessment: recognize that even advanced readers rely on phonological processing, so phonology training can benefit lifelong reading proficiency.

The IPA, Phonemes, and Spelling Patterns: Practical Details

  • NZ English sounds overview (from a common educational clip):

    • Total sounds: 44extor4544 ext{ or } 45 (depends on dialect)

    • Consonants: 2525; Vowels: 2020

    • Letters in the alphabet: 26; therefore, multiple-letter spellings represent the same sounds.

    • Spelling patterns: about 150150 common patterns; about 250250 total patterns used in representing sounds.

  • How reading instruction uses phonology:

    • Clear and pure articulation of sounds helps beginning and struggling learners hear and use correct sounds.

  • The idea of an integrated sound map for English and other languages:

    • While English shows irregularities, understanding IPA and phoneme inventories supports cross-language literacy analysis and multilingual reading development.

Key Concepts and Takeaways

  • Core distinction: reading makes word boundaries explicit; speech does not, which complicates real-time segmentation in listening.

  • Orthography vs phonology are distinct yet interlinked systems; reading requires mapping between the two, with English showing notable irregularities.

  • Phonological awareness is foundational for literacy; explicit teaching of phonemes, graphemes, and spelling patterns supports decoding and encoding.

  • Reading research often uses single-word tasks (lexical decisions, naming) and text-based tasks (eye-tracking, priming) to isolate subprocesses; however, real-world reading involves larger texts and integrative comprehension.

  • Five major research methods provide converging evidence on how reading unfolds: lexical decision, naming, eye-tracking, priming, and neuroimaging.

  • Phonology influences reading at all ages; even silent reading in adults engages phonological representations, sometimes influenced by accent and neighbor relationships.

  • Deaf readers still rely on phonological-like representations or alternative modalities during reading, underscoring the robustness of phonological processing in literacy.

  • Educational implications emphasize balanced literacy: decode-to-meaning integration, phonological awareness training, and strategies to develop fluent, meaning-rich reading.

  • Important caveat: much of the literature has a focus on English; cross-language reading research is essential to avoid biases and to inform multilingual literacy practices.

Notable Examples and Anecdotes from the Lecture

  • The cat → catapult example demonstrates how words can expand into larger lexical items by attaching different morphemes and meanings.

  • The classic jumbled-letter example illustrates word recognition relying on the first and last letters and overall word shape, though the attribution to Cambridge University is contested.

  • A limerick eye-tracking study showed how readers from different parts of England backtrack to verify rhymes, indicating engagement of phonology during silent reading across dialects.

  • Tongue twisters in silent reading reveal phonological processing even without aloud speech: readers showed increased fixations and processing difficulty.

  • A study on phonological neighbors showed that reading is influenced by neighbors that sound similar; when a neighbor is a real word and phonologically similar, processing can slow due to competition; when the neighbor is not a real word, processing can be smoother.

  • A classic example of phonological priming: readers process words more quickly when primes share phonology, implying fast, automatic phonological activation during reading.

Connections to Previous Lectures and Real-World Relevance

  • Connects to broader language processing topics: how people understand sentences, lexical access, and semantic integration.

  • Real-world relevance for education: highlights why phonological awareness training matters in early schooling and why reading to learn requires strong decoding and comprehension skills.

  • Practical implications for multilingual education: cross-language orthography-phonology mappings influence how quickly children learn to read in different languages; supports teaching approaches tailored to orthographic transparency.

  • Ethical and methodological considerations: overreliance on English-centric studies may bias understanding; cross-language research is necessary for inclusive literacy education.

Final Thoughts

  • Reading is a complex, multi-component system that draws on orthography, phonology, semantics, and syntax to build meaning.

  • While reading and speaking share foundations, the modality-specific cues (punctuation vs prosody, word boundaries, coarticulation) create distinct processing demands.

  • Ongoing research continually reveals the depth of phonology’s involvement in reading, from early decoding to silent, adult comprehension, including implications for education, multilingualism, and cognitive science.

  • The field benefits from cross-language studies to avoid English-centric bias and to better understand universal versus language-specific reading processes.
