[Figure from Ladefoged 1996.]
On the distance hypothesis, see for example Turk et al 1994.
Acoustics (F1) as a proxy for distance to target
+Full mediation
+Full mediation (the effect of vowel is fully mediated by F1)
When the speaker gains control over a mechanical/physiological process (and the process “enters the phonetics” of the language).
–Bermúdez-Otero 2013
-No mediation
+No mediation (vowel and F1 independently affect duration)
Process scattering
-Process (or rule) scattering is the scenario in which the same process coexists in two different levels of language.
+Process (or rule) scattering is the scenario by which a process coexists in multiple levels of the language.
–Bermúdez-Otero 2013
Process scattering (revised)
+Process scattering is the scenario by which two versions of the same process coexist in the language, either in the same level or in consecutive levels.
+Partial mediation
+Partial mediation (vowel has a direct and mediated effect on duration)
In a model with vowel and F1 as predictors:
The results are compatible with the (c) Partial Mediation hypothesis.
+The results are compatible with the (c) Partial Mediation hypothesis (Process Scattering).
This means that:
Each vowel must have a duration target.
Distance to target explains duration within each vowel category.
Each vowel must have its own duration target.
Within each vowel category, distance to target further modulates duration.
