This paper examines the processing of height and place contrasts in vowels in words and pseudowords, using mismatch negativity (MMN) to determine firstly whether asymmetries resulting from underlying representations found in the processing of vowels in isolation will remain in a word context and secondly whether there is any difference in the way these phonological differences manifest in pseudowords. The stimuli are two sets of English ablaut verbs and corresponding pseudowords (sit~sat/*sif~*saf and get~got/*gef~*gof) contrasting in vowel height ([HIGH] vs.[LOW]) and place of articulation ([CORONAL] vs. [DORSAL]). In line with previous research, the results show a processing asymmetry for place of articulation in both words and nonwords, while different vowel heights result in symmetrical MMN patterns. These findings confirm that an underspecification account provides the best explanation for featural processing and that phonological information is independent of lexical status.

Prefixes and suffixes display distinctive linguistic behaviors. Not only does a crosslinguistic asymmetry exist between them in terms of structural properties, combinatorial constraints, and frequency, but there is also extensive evidence that prefixes and suffixes are processed differently. To further investigate the differences in how prefixes and suffixes are processed, we conducted five crossmodal priming experiments in Bengali, a language rich in derivational morphology. Although all combinations of stems, prefixes, and suffixes provided facilitation, we found that stems primed related prefixed forms to a greater degree than they primed related suffixed forms. Furthermore, morphologically related prefixed forms primed other prefixed forms more than suffixed forms primed related suffixed forms. On the basis of these findings, we propose that the asymmetry in how prefixes and suffixes are processed is due not only to differences in perception, reading, and inhibition from the phonological cohort, but also to the salience of the morpheme boundaries in affixed word representations during recognition.
