MLAT Phonetic Coding & Sound Discrimination 5 — Questions and Answers
Question 1: A student is taught that the symbol '☆' represents the sound /k/ and '◆' represents /g/. Later she must identify which symbol goes with a heard syllable. This task assesses:
- Grammatical sensitivity
- Sound-symbol association learning (Correct answer)
- Inductive language learning
- Rote memorization of vocabulary
Correct answer: Sound-symbol association learning
Linking an arbitrary visual symbol to a specific sound is a direct measure of sound-symbol association, a core component of phonetic coding ability.
Question 2: Which of the following pairs of sounds share the same place of articulation?
- /p/ and /k/
- /t/ and /d/ (Correct answer)
- /f/ and /b/
- /m/ and /s/
Correct answer: /t/ and /d/
Both /t/ and /d/ are alveolar consonants — they are both produced with the tongue tip touching or near the alveolar ridge.
Question 3: Which scenario best demonstrates poor phonetic memory, as measured by the MLAT?
- Confusing the grammar rules of two similar languages
- Forgetting the sound of a new word by the end of a lesson (Correct answer)
- Mispronouncing a word due to spelling interference
- Failing to understand connected speech at high speed
Correct answer: Forgetting the sound of a new word by the end of a lesson
Phonetic memory involves retaining sound patterns of new words; forgetting a word's sound despite recent exposure directly reflects weak phonetic encoding.
Question 4: The distinction between 'tense' and 'lax' vowels in English (e.g., /iː/ vs. /ɪ/) involves differences in:
- Voicing only
- Muscle tension, duration, and height (Correct answer)
- Aspiration
- Nasality
Correct answer: Muscle tension, duration, and height
Tense vowels like /iː/ are produced with greater muscular tension, longer duration, and a higher, more peripheral tongue position than their lax counterparts like /ɪ/.
Question 5: In the context of MLAT phonetic tasks, what does it mean when two sounds are said to be in 'complementary distribution'?
- They can substitute for each other without changing meaning
- They never appear in the same phonetic environment (Correct answer)
- They form a minimal pair
- They are both voiced fricatives
Correct answer: They never appear in the same phonetic environment
Sounds in complementary distribution never occur in the same phonetic environment, which is a hallmark of allophones rather than separate phonemes.
Question 6: A test-taker hears the nonsense word 'velmak' and must write it phonetically. When she hears it again 10 minutes later, she recognizes it immediately. This success is best attributed to:
- Strong grammatical sensitivity
- Effective phonetic coding and retention (Correct answer)
- High rote memory for words with meaning
- Excellent inductive reasoning skills
Correct answer: Effective phonetic coding and retention
Accurately encoding and later recognizing a meaningless sound sequence demonstrates strong phonetic coding — storing sounds independent of semantic content.
Question 7: Research on MLAT scores consistently shows that phonetic coding ability is a better predictor of foreign language success than which of the following?
- General intelligence (IQ)
- Prior foreign language experience (Correct answer)
- Native language reading ability
- Working memory capacity
Correct answer: Prior foreign language experience
Studies show that prior foreign language exposure does not strongly predict new language acquisition, whereas phonetic coding ability does, because each language has a unique sound system.
