Coarticulation Study 1
Stimuli: 12 CV syllables (four fricatives in three vowel contexts: i, u, a;
e.g., si, su, sa) Computer excised the vowel portion of each
syllable.
Procedure: Remaining "consonant" portion played to subjects.
Task: Identify the missing vowel.
Results: [i], [u] reliably identified; [a] not
Conclusion: Fricative portion contains information about vowel

Coarticulation Study 2 -1
Stimuli: C1VC2 syllables with [b]: bVb 9 different vowels: beeb, bib, babe, bobComputer divided syllables in X Y Z
X: transition from C1 to V (Y); Z: transition from V to C2; Y central vocalic (vowel) portion
Procedure: Subjects heard: 1. XYZ
2. X—Z (— is a silent gap) 3. Y (steady state portion) 4. Y (fixed length steady state portion)
5. XZ
Task: Identify the vowel in each test stimulus

Coarticulation Study 2 - 2
Results: Types 2 (X—Z), 1 (XYZ) accurate Types 3, 5 "significantly more errors" Type 4 worst
Conclusion: "…formant transitions and vowel duration are more important cues to the identity of vowels than a fixed sample of the steady- state information." (126 b)

Fodor's Criteria for Modularity
1) domain specific
2) operates on a mandatory basis
3) fast
4) unaffected by feedback (from oth
er modules)

Visual Influences on Speech Perception
Procedure: Present visual picture of someone saying [ga] Synchronized with the sound [ba]
Task: Subject identifies the sound heard
Result: Subject "hears" and identifies it as [da]
Conclusion: Place of articulation detected by eye Manner of articulation detected by ear

Duration of fixations decrease
Regressions per 100 words decrease
Fixations per 100 words (-Regressions) decrease
Number of words per fixation increase

Word-Superiority Effect -1
Stimuli: words, non-words, letters
Procedure: Show subjects one of these using tachistoscope briefly: word (a word) owrd (a non-word) d or k (a letter)
Task: Reply to "Did you see a given letter (e.g.,
"d") in final position?"
18
Word-Superiority Effect - 2
Results: More accurate if the letter appeared
in a word.
Conclusion: The word has an effect on letter
recognition. There must be some top-
down processing— though bottom-up
processing can occur
