There is growing evidence that prosody is a powerful cue infants make use for segmenting spoken utterances into word-
like units. The language specific segmentation, as well as the syntactic elements are bootstrapped via perceptual patterns
available at both lexical and phrase levels. Supposedly, the attunement to the native language prosodic properties starts prenatally,
emphasizing the prominent role of the intrauterine period in language acquisition. A total of 82 term and preterm infants were
studied on one occasion at corrected 6 months of age (n=40) or at 10 months of age (n=42) respectively. Preterm infants (n=34)
were divided regarding gestational age into 30-32 weeks (n=17) and 33–36 weeks (n=17) groups and compared. Mismatch
negativity event related brain potential (ERP) component (mismatch response, e.g. MMR in more general) was recorded and
analyzed. The ERPs elicited by frequent (standard) and rare (deviant) pseudo-words by using a passive oddball paradigm of
two conditions: (1) standards of legal stress patterns interspersed with deviants of illegal one (stress on the second syllable),
and (2) standards of illegal stress and deviants of legal one. We found no significant difference in MMR responses between
6th and 10th months of age, however processing patterns differed (p<0.02) between preterm and term infants. Furthermore
severity of prematurity associated with less stress discrimination accuracy at the illegal deviant condition (p<0.05). These
results strengthen the view that longer extra-uterine language exposure doesn’t redound as a compensatory effect.
