Welcome to Phonological Development (AQA Paper 1, Section B)
Hello! Welcome to your revision notes on Phonological Development for AQA A-Level English Language (7702). This chapter sits inside Paper 1 Section B: Children's language development (which covers ages 0 to 11 years).
In this section of the exam, you will analyse transcripts of children speaking. To achieve top marks, you need to explain how children learn to produce and understand the sounds of English. Don't worry if phonetic symbols and terminology seem intimidating at first—we will break down every single concept step-by-step with clear examples!
Exam Basics to Keep in Mind:
• Paper 1: Language, the Individual and Society (2 hours 30 minutes total, worth 40% of your A Level).
• Section B: Worth 30 marks. You will choose one discursive essay question based on provided transcript data.
• AO1: Applying linguistic methods and precise terminology.
• AO2: Demonstrating critical understanding of concepts and developmental theories.
• Secret Weapon: AQA provides an IPA (International Phonetic Alphabet) Phonemic Symbols Reference Chart on the back page of your exam paper. You do not have to memorise every symbol from scratch!
1. Phonology vs. Graphology: The Cardinal Rule
Before jumping into child speech, let's clear up the single most common mistake reported by examiners:
• Phonology: The study of speech sounds (phonemes), written between forward slashes: /kæt/.
• Graphology / Orthography: The study of written letters (graphemes) and spelling, written inside angle brackets: <cat>.
Golden Rule for Paper 1 Section B: Never write "the child left out the letter 't'". Instead, write: "The child deleted the voiceless alveolar plosive consonant sound /t/." Children acquire spoken sound systems long before they learn alphabet letters!
2. Pre-Verbal & Early Vocal Stages (0 to 12 Months)
Long before a child says their first recognisable word, their vocal tract undergoes intense physical practice. Here is how speech sounds emerge in sequence:
Stage 1: Vegetative / Reflexive Stage (0–2 months)
• What happens: Completely involuntary, biological reflex sounds.
• Examples: Crying, burping, coughing, and sneezing.
• Purpose: Communicates distress and exercises vocal cords reflexively.
Stage 2: Cooing & Laughing (2–5 months)
• What happens: Open vowel-like sounds such as /uː/ and /ɑː/, combined with back-of-the-mouth velar consonants like /k/ and /ɡ/.
• Why back sounds first? The infant is often lying down, so the back of the tongue naturally contacts the soft palate (velum).
• Purpose: Expresses comfort, contentment, and pleasure.
Stage 3: Vocal Play (4–7 months)
• What happens: The baby experiments with pitch (squealing, growling), volume (loud grunts), and friction sounds.
• Purpose: Practising controlled muscle movements of the lips, tongue, and vocal tract.
Stage 4: Babbling (6–12 months)
Babbling is rhythmic and starts resembling real human language syllables (Consonant + Vowel, or CV). It splits into two key types:
1. Canonical / Reduplicated Babbling: The child repeats identical CV syllables over and over (e.g., [ba-ba-ba], [da-da-da]).
2. Variegated / Non-reduplicated Babbling: The child mixes up different consonants and vowels together in varied sequences (e.g., [ba-da-ma]).
Stage 5: Proto-words (9–12 months)
• What happens: Also called Phonetically Consistent Forms (PCFs). These are invented sound clusters that a child uses consistently to refer to a specific object or situation (e.g., saying [didi] every time they want their blanket).
• Crucial distinction: They are not real adult words yet, but they show clear, intentional symbolic meaning.
Quick Summary Table: Pre-Verbal Stages
• 0–2m: Vegetative (crying, burping)
• 2–5m: Cooing (/uː/, /ɑː/, /k/, /ɡ/)
• 4–7m: Vocal Play (pitch & volume control)
• 6–12m: Babbling (reduplicated [ba-ba] $\rightarrow$ variegated [ba-da-ma])
• 9–12m: Proto-words (consistent invented labels)
3. Phonological Simplification Processes
When children start speaking adult words, their physical articulators (tongue, lips, teeth, vocal cords) are still developing neuromuscular coordination. To cope, they use systematic, rule-governed simplification processes.
Examiner Tip: Never dismiss child pronunciation as random "baby talk" or "slang". Identify the exact linguistic process below!
A. Deletion
Dropping a sound or an entire syllable from a word:
• Final Consonant Deletion: Omitting the ending consonant sound.
Example: /kæt/ $\rightarrow$ [kæ] (saying "ca" instead of "cat").
• Initial Consonant Deletion: Omitting the opening consonant sound (less common).
Example: /dɒɡ/ $\rightarrow$ [ɒɡ] (saying "og" instead of "dog").
• Weak / Unstressed Syllable Deletion: Dropping the unstressed beat in a multisyllabic word.
Example: /bəˈnɑːnə/ $\rightarrow$ [ˈnɑːnə] (saying "nana" instead of "banana").
B. Consonant Cluster Reduction
A "consonant cluster" is two or more consonants side-by-side (like /sp/, /fr/, /str/). Children reduce the cluster down to a single, easier consonant sound.
• Example 1: /spɪl/ $\rightarrow$ [pɪl] ("spill" becomes "pill").
• Example 2: /frɒɡ/ $\rightarrow$ [fɒɡ] ("frog" becomes "fog").
C. Substitution
Replacing a harder sound with an easier sound. There are several specific varieties:
• Stopping: Replacing a continuous, friction sound (a fricative like /s, z, f, v/) with a complete "stop" / plosive sound (/p, b, t, d, k, ɡ/).
Example: /siː/ $\rightarrow$ [tiː] ("see" becomes "tee"); /væn/ $\rightarrow$ [bæn] ("van" becomes "ban").
• Fronting (Velar / Palatal Fronting): Replacing a sound made at the back of the mouth (velar /k, ɡ/) with a sound made at the front of the mouth (alveolar /t, d/).
Example: /kɑː/ $\rightarrow$ [tɑː] ("car" becomes "tar"); /ɡəʊ/ $\rightarrow$ [dəʊ] ("go" becomes "doe").
• Gliding: Replacing "liquid" sounds (/l, r/) with smooth "glide / approximant" sounds (/w, j/).
Example: /red/ $\rightarrow$ [wed] ("red" becomes "wed"); /læmp/ $\rightarrow$ [jæmp] ("lamp" becomes "yamp").
• Voicing & De-voicing: Changing whether the vocal cords vibrate (e.g., swapping voiceless /p, t, k/ for voiced /b, d, ɡ/ at the start of words, or de-voicing sounds at the end of words).
D. Assimilation
A sound changes to match or mimic another neighbouring sound in the same word:
• Velar Assimilation: /dɒɡ/ $\rightarrow$ [ɡɒɡ] ("dog" becomes "gog" because the back sound /ɡ/ influences the front /d/).
• Labial Assimilation: /tʌb/ $\rightarrow$ [bʌb] ("tub" becomes "bub" because the lip sound /b/ influences the /t/).
E. Addition / Epenthesis
Inserting an extra sound into a word—frequently the neutral schwa vowel /ə/—to break up tricky consonant clusters.
Example: /bluː/ $\rightarrow$ [bəˈluː] ("blue" pronounced as "buh-lue").
F. Reduplication
Repeating an entire syllable or part of a syllable to create an easy CV-CV rhythm.
Example: "bottle" $\rightarrow$ [bɒbɒ]; "water" $\rightarrow$ [wɑːwɑː].
4. Phoneme Acquisition Orders
Why do children make these predictable substitutions? Because human speech sounds develop in a clear developmental sequence based on manner and place of articulation.
Early Acquired Sounds (Typically mastered by ages 2–3):
• Plosives: /p, b, t, d, k, ɡ/ (complete blockage and sudden release of air).
• Nasals: /m, n/ (air passes freely through the nose).
• Approximants / Glides: /w, j/ (gliding articulators).
Why early? Many of these are bilabial (using both lips, like /p, b, m/) or alveolar (tongue tip on the roof ridge, like /t, d, n/). They are visually obvious on an adult's face and simple to execute physically.
Later Acquired Sounds (Typically mastered between ages 4–7+):
• Fricatives: /f, v, s, z, ʃ, ʒ/ and especially the dental fricatives /θ/ (as in thin) and /ð/ (as in this).
• Affricates: /tʃ/ (as in church) and /dʒ/ (as in judge).
• Liquids: /l/ and /r/.
Why later? These require precise, minute motor control to direct airflow through narrow articulatory gaps without closing them off entirely. As researched by Pamela Dodd et al. and Arthur O’Connor, complete mastery of complex sound combinations (e.g., three-consonant clusters like /str/ in string) continues up to age 7 to 8.
5. Key Phonological Research & Interaction
The "Fis" Phenomenon (Berko and Brown, 1960)
This classic study proves that phonological perception (comprehension) develops ahead of phonological production (articulation).
• The Experiment: A child referred to his plastic toy fish as a "fis" (/fɪs/).
• The Adult's Test: When the adult asked, "Is this your fis?", the child firmly rejected it: "No, my fis."
• The Outcome: When the adult asked, "Is this your fish?", the child happily agreed: "Yes, my fis."
• Linguistic Takeaway: The child had the correct adult mental representation (/fɪʃ/) stored in their cognitive system and could hear the difference, even though their vocal apparatus could only physically produce /fɪs/.
Child-Directed Speech (CDS) — Phonological Features
When caregivers talk to infants and young children (researched by Catherine Snow, Jerome Bruner, and Charles Ferguson), they naturally adjust their phonology to support language acquisition:
• Higher overall pitch & wider pitch range: Captures and holds the child's attention.
• Exaggerated intonation contours: Sing-song prosody that highlights emotional cues and sentence types.
• Slower tempo with elongated vowels: Gives the child more acoustic processing time.
• Hyperarticulation: Pronouncing word boundaries distinctly and clearly.
• Diminutive syllable structures: Adding -y or -ie to create simple CVCV patterns (e.g., doggy, horsey, tummy).
6. Examiner Advice: How to Tackle Data Transcripts
When writing your essay for Section B, avoid "feature spotting" and apply this analytical workflow:
1. Spot the exact sound pattern: Don't just write "the child talks like a baby."
2. Name the process using technical terms: Identify whether it is stopping, velar fronting, gliding, or cluster reduction.
3. Analyse prosodics: Look at transcript conventions like pauses (.), emphatic stress (indicated by capitals or underlining), and rising intonation (? or //). These reveal how children use rhythm and pitch to signal meaning before their grammar is fully formed.
4. Connect to theory/evidence: Explain whether the data reflects the Fis Phenomenon (perception vs. production), physiological articulatory constraints, or caregiver phonological scaffolding (CDS).
