Prototypicality judgments as inverted perception

Abstract:
In a prototypicality task in the laboratory, the preferred
auditory token of the vowel /i/ is much more peripheral,
i.e. has a much lower F1, than the most common token of
/i/ in the listener's language environment or the token
that the listener herself would most frequently produce
(Johnson, Flemming & Wright 1993). This can be explained
within a parallel model of phonology and phonetics (Boersma
2005), under the single additional assumption that representation
s that lie outside the minimal requirements of the task
are not activated. The difference between prototype and
modal produced token is then explained by the activity of
articulatory constraints in production and their inactivity
in the prototypicality task. The difference between prototype
and modal environmental token follows automatically from
the constraint ranking that results from lexicon-driven
perceptual learning.
