In the current study, we test the discrimination of four basic English tone contours
in monosyllabic words by Polish learners using an AXB task and we compare these
results to the results of an identifi cation test. Discrimination does not require access
to phonological labels and is claimed to tap core auditory mechanism. Relatively
high discrimination performance by Polish learners and poor identifi cation performance
indicate that diffi culties with correct identifi cation of English tones are solely
diffi culties with labelling
