The architecture of neural auditory processing suggests that syllable prosody might not be that tightly linked with phonemes. Crucially, the different temporal availability of both types of information in the acoustic input
is associated with specialized auditory processing networks respectively. Information that characterizes phonemes varies at a fast rate. Typically, rapid transitions ranging between 20 and 100 ms establish distinctive features, such as the voice onset time difference between /b/ and /p/. Information that characterizes syllable varies somewhat slower. Typically, features of pitch, loudness Nutlin-3a in vitro and duration ranging between 100 and 300 ms are relevant to distinguish between stressed and unstressed syllables such as MUS and mus. There is some neurocognitive evidence for lateralized specialization of auditory cortices to different temporal integration windows. Fast acoustic variation in the range of phoneme-relevant information appears to be pre-dominantly processed in the left hemisphere, slower acoustic variation in the click here range of syllable-relevant information appears to be pre-dominantly processed in the right hemisphere (e.g., Boemio et al., 2005, Giraud and Poeppel, 2012, Giraud et al., 2007, Luo and Poeppel, 2012 and Zatorre and Belin, 2001). Yet, whether the initial separation of both types of information is maintained at higher language-specific processing levels has
to be figured out. Previous behavioral evidence for independent processing of syllable prosody along
the spoken word recognition pathway is weak. In four auditory priming experiments, Slowiaczek, Soltano, and Bernstein (2006) failed to show pure stress priming. Neither lexical decision latencies nor shadowing differed for spoken target words that either were preceded by spoken words with the same stress pattern (RAting – LIFEtime) or by spoken words with a different stress pattern (RAting – ciGAR). That is, if there are some types of abstract prosodic representations, their activation might not be obligatorily reflected in response oxyclozanide latencies obtained in auditory priming tasks. Event-Related Potentials (ERPs) recorded in word onset priming previously revealed some evidence for independent processing of syllable prosody and phonemes. In a former study of us, we were selectively interested in the processing of pitch contours (Friedrich, Kotz, Friederici, & Alter, 2004). We extracted the first syllables of initially stressed German words, such as KObold (Engl. goblin), and of initially unstressed German words, such as faSAN (Engl. pheasant). We calculated the mean pitch contours of the stressed word onset syllables, such as KO-, and of the unstressed word onset syllables, such as fa-, and applied them to each individual syllable. This resulted in one version of each syllable with a stressed pitch contour and another version of the same syllable with an unstressed pitch contour. We used those syllables as primes.
