“…Moreover, a pre-existing representation from the lexicon could serve to constrain possible mappings for English words relative to novel words [22,38]. Alternatively, it is possible that a neighborhood of highly similar English words was activated as a set of possible matches for the pseudo-English stimulus [45]. In either case, although transformation of the Foreign strings to a phonological representation may have placed greater demands on pLIPC control processes, the pseudo-English words may have resulted in a greater load on the phonological system because multiple representations may have been brought on-line.…”

Assembling and encoding word representations: fMRI subsequent memory effects implicate a role for phonological control

Novel word learning is central to the flexibility inherent in the human language capacity. Word learning may partially depend on long-term memory formation during the assembly of phonological representations from orthographic inputs. In the present study, event-related functional magnetic resonance imaging (fMRI) examined the contributions of phonological control-a component of the verbal working memory system-to phonological assembly and word learning. Subjects were scanned while making syllable decisions about visually presented familiar (English) and novel (pseudo-English and Foreign) words, a task that required retrieval and analysis of existing phonological codes or the assembly and analysis of novel representations. Results revealed that left inferior prefrontal cortex (LIPC) and bilateral parietal cortices were differentially engaged during the processing of novel words, suggesting that this circuit is recruited during phonological assembly. A subsequent memory analysis that examined the relation between fMRI signal and the subject's ability to later remember the words (a measure of effective memory formation) revealed that the magnitude of activation in LIPC, bilateral superior parietal, and left inferior parietal cortices was positively correlated with later memory. Moreover, although the magnitude of the subsequent memory effect in parietal cortex was not significantly affected by word type, this effect was greater in posterior LIPC for novel (pseudo-English) than for familiar (English) words. In the course of subserving the assembly of novel word representations, the phonological (articulatory) control component of the phonological system appears to play a central role in the encoding of novel words into long-term memory.

“…During subsequent language development in children, high phonotactic probability leads to a faster acquisition of words (Storkel, 2001), a better recall of non-words (Gathercole et al, 1999) and a higher accuracy of non-word repetition (Coady and Aslin, 2004). In adults, phonotactic probability affects a large number of language processes, ranging from the speed and ease of spoken word recognition (Vitevitch and Luce, 1999) to listeners' metalinguistic judgments of word-likeness (Bailey and Hahn, 2001). Although these and other behavioral effects are relatively well documented (for a review see Auer and Luce, 2003), neural correlates of phonotactic probability remain largely unexplored.…”

Objective: Ample behavioral evidence suggests that distributional properties of the language environment influence the processing of speech. Yet, how these characteristics are reflected in neural processes remains largely unknown. The present ERP study investigates neurophysiological correlates of phonotactic probability: the distributional frequency of phoneme combinations. Methods: We employed an ERP measure indicative of experience-dependent auditory memory traces, the mismatch negativity (MMN). We presented pairs of non-words that differed by the degree of phonotactic probability in a modified passive oddball design that minimizes the contribution of acoustic processes. Results: In Experiment 1 the non-word with high phonotactic probability (notsel) elicited a significantly enhanced MMN as compared to the non-word with low phonotactic probability (notkel). In Experiment 2 this finding was replicated with a non-word pair with a smaller acoustic difference (notsel-notfel). An MMN enhancement was not observed in a third acoustic control experiment with stimuli having comparable phonotactic probability (so-fo). Conclusions: Our data suggest that auditory cortical responses to phoneme clusters are modulated by statistical regularities of phoneme combinations. Significance: This study indicates that the language environment is relevant in shaping the neural processing of speech. Furthermore, it provides a potentially useful design for investigating implicit phonological processing in children with anomalous language functions like dyslexia.

“…Thus, the appearance of such patterns in utterances signals the likely location of word boundaries. Once again, there is empirical evidence that adult listeners take advantage of such phonotactic patterns in segmenting and recognizing words (McQueen, 1998;Vitevitch & Luce, 1999). Finally, another source of information in the acoustic signal that potentially cues word boundaries resides in the positioning of certain allophones (Bolinger & Gerstman, 1957;Church, 1987;Hockett, 1955, Lehiste, 1960.…”

Lexical viability constraints on speech segmentation by infants

The Possible Word Constraint limits the number of lexical candidates considered in speech recognition by stipulating that input should be parsed into a string of lexically viable chunks. For instance, an isolated single consonant is not a feasible word candidate. Any segmentation containing such a chunk is disfavored. Five experiments using the head-turn preference procedure investigated whether, like adults, 12-month-olds observe this constraint in word recognition. In Experiments 1 and 2, infants were familiarized with target words (e.g., rush), then tested on lists of non-
