How well can non-native length contrasts for vowels and for consonants be perceived and
is one type more difficult than the other? Three listener groups (native Italian and German
as well as advanced German learners of Italian) performed a speeded same–different
task involving vocalic and consonantal length contrasts as well as segmental contrasts as
controls. Phonologically, Italian, but not German, has a consonantal length contrast, while
German, but not Italian, has a vocalic length contrast. Analysis of responses yielded a clear
asymmetry: A non-native vowel length contrast was perceived just as well as the native
consonantal length contrast. A non-native consonantal length contrast, however, was
perceived poorly compared to the native vocalic length contrast: Italians showed higher
sensitivity for consonantal length than German learners of Italian, who in turn were better
than German non-learners. Reaction time analyses indicated that, despite displaying higher
accuracy, the decision was just as difficult for learners as for non-learners, suggesting
different types of difficulty for listeners with and without experience with a consonantal
length contrast.
