Phonological priming in German Sign Language

A number of studies provide evidence for a phonological priming effect in the recognition of single signs based on phonological parameters and that the specific phonological parameters modulated in the priming effect can influence the robustness of this effect. This eye tracking study on German Sign Language examined phonological priming effects at the sentence level, while varying the phonological relationship between prime-target sign pairs. We recorded participants’ eye movements while presenting videos of sentences containing either related or unrelated prime-target sign pairs, and pictures of the target and an unrelated distractor. We observed a phonological priming effect for sign pairs sharing handshape and movement while differing in location parameter. Taken together, the data suggest a difference in the contribution of sign parameters to sign recognition and that sub-lexical features influence sign language processing.

Neural Processes Underlying Nonword Rhyme Differentiate Eventual Stuttering Persistence and Recovery

Purpose Phonological skills have been associated with developmental stuttering. The current study aimed to determine whether the neural processes underlying phonology, specifically for nonword rhyming, differentiated stuttering persistence and recovery. Method Twenty-six children who stutter (CWS) and 18 children who do not stutter, aged 5 years, completed an auditory nonword rhyming task. Event-related brain potentials were elicited by prime, rhyming, and nonrhyming targets. CWS were followed longitudinally to determine eventual persistence ( n = 14) or recovery ( n = 12). This is a retrospective analysis of data acquired when all CWS presented as stuttering. Results CWS who eventually recovered and children who do not stutter exhibited the expected rhyme effect, with larger event-related brain potential amplitudes elicited by nonrhyme targets compared to rhyme targets. In contrast, CWS who eventually persisted exhibited a reverse rhyme effect, with larger responses to rhyme than nonrhyme targets. Conclusions These findings suggest that CWS who eventually persisted are not receiving the same benefit of phonological priming as CWS who eventually recovered for complex nonword rhyming tasks. These results indicate divergent patterns of phonological processing in young CWS who eventually persisted, especially for difficult tasks with limited semantic context, and suggest that the age of 5 years may be an important developmental period for phonology in CWS.

Phonological priming in German Sign Language: An eye tracking study using the Visual World Paradigm

Various studies provide evidence for a phonological priming effect in the recognition of single signs based on phonological parameters, i.e., handshape, location and movement. In addition, some of these studies show that phonological parameters influence this effect differently. The current eye tracking study on German Sign Language examined the presence of a phonological priming effect at the sentence level depending on the phonological relation of prime-target sign pairs. We recorded participants’ eye movements while presenting a video of sentences containing either related or unrelated prime-target sign pairs, and a picture of the target and the distractor. The data provided evidence for a phonological priming effect for sign pairs sharing handshape and movement while differing in location. Moreover, a difference between parameters in their contribution to sign recognition was suggested such that recognition was facilitated for signs sharing handshape, but was inhibited for signs sharing location. Showing that sub-lexical features influence sign language processing.

A mare in a pub? Nonnative facilitation in phonological priming

A phonological priming experiment reports inhibition for Russian prime-target pairs with onset overlap in native speakers. When preceded by the phonological prime /kabɨla/, the target /kabak/ ( кобыла – КАБАК, mare – PUB) takes longer to respond than the same target preceded by a phonologically unrelated word. English-speaking late learners of Russian also show inhibition, but only for high-frequency prime-target pairs. Conversely, they show facilitation for low-frequency pairs. In semantic priming (e.g. carnation – DAISY), facilitation is observed for the same two lexical frequency ranges both in native speakers and learners of Russian, suggesting that the primes and targets in the low-frequency range are familiar to the nonnative participants. We interpret nonnative phonological facilitation for low-frequency words as evidence for sublexical processing of less familiar words that is accompanied by reduced lexical competition in nonnative lexical access. We posit that low lexical competition is due to unfaithful, or fuzzy phonolexical representations: nonnative speakers are unsure about the exact phonological form of low-frequency words. Such unfaithful representations are not strongly engaged in lexical competition and selection. High reliance on sublexical rather than lexical processing may be a general property of nonnative word recognition in case when the words are less familiar and have a low level of entrenchment.

Phonological priming and the role of phonology in nonnative word recognition

Research on nonnative auditory word recognition makes use of a lexical decision task with phonological priming to explore the role of phonological form in nonnative lexical access. In a medium-lag lexical decision task with phonological priming, nonnative speakers treat minimal pairs of words differentiated by a difficult phonological contrast as a repetition of the same word. While native speakers show facilitation in medium-lag priming only for identical word pairs, nonnative speakers also show facilitation for minimal pairs. In short-lag phonological priming, when the prime and the target have phonologically overlapping onsets, nonnative speakers show facilitation, while native speakers show inhibition. This review discusses two possible reasons for facilitation in nonnative phonological priming: reduced sensitivity to nonnative phonological contrasts, and reduced lexical competition of nonnative words with underdifferentiated, or fuzzy phonolexical representations. Nonnative words may be processed sublexically, which leads to sublexical facilitation instead of the inhibition resulting from lexical competition.

Lexical Phonological Networks in Children with Down Syndrome: An Initial Syllable Similarity Priming Task with an Eye-Tracking Method

Typically-developing (TD) infants as young as 24 months of age use phonological information to establish links between the words of their early lexicons (Mani & Plunkett, 2010; 2011), which facilitates word recognition and learning. However, Down syndrome (DS) children are reported to have difficulties in learning phonological representations (Jarrold & Thorn & Stephens, 2009). The present study aimed to evaluate if DS children establish lexical networks based on phonological similarity by exploring the effects of lexical competition in a phonological priming task. We evaluated 24 children with DS (mental verbal age; M= 40 months) and 24 children with TD (mental verbal age; M= 40 months), matched by receptive vocabulary size, with a phonological priming adaptation of the intermodal preferential looking task. Children with DS showed inhibition of target recognition in related trials compared to unrelated trials. Children with TD showed an absence of priming effects. Further analysis revealed a relationship between the prime cohort size and the level of inhibition of target recognition for both groups. Our results suggest children with DS possess sufficiently detailed phonological representations that allow them to efficiently cluster their lexical entries based on phonological similarities. Moreover, results are thought to reflect differences in the lexical competition processes between the TD and DS groups.
