Phonological Priming in Children with Developmental Language Disorder

<p>本研究利用跨模式圖字干擾作業探討與比較習華語發展性語言障礙兒童(DLD)和典型發展兒童(TD)在音節、聲調與次音節單位（聲母及韻母）的音韻促發效應，以更深入了解兒童音韻表徵的型態及處理歷程。共有16名4至6歲11個月的DLD兒童和16名與其性別和年齡配對的TD兒童。促發項之音韻類型包括同音節、同聲母、同韻母、同聲調及無關項；促發項相對於目標項所呈現的時間為前150毫秒(SOA -150)、同時(SOA 0)及後150毫秒(SOA +150)。研究結果指出：(1)TD兒童的反應速度和正確率優於DLD兒童；(2)兩組兒童皆呈現同音節促進效應，且均無同聲調促進效應，代表華語兒童詞彙提取歷程中已具有音節框架的存在，而聲調對於詞彙提取的貢獻有限；(3)兩組主要的差異在次音節單位，DLD兒童在SOA -150和SOA +150時均呈現同韻母促進效應，而TD兒童僅在SOA 0呈現同聲母抑制效應。據此推論DLD兒童在次音節單位的處理方式與TD兒童不同，TD兒童可能是採用Cohort model的處理模式，而DLD兒童則未使用或尚未發展成熟到能使用此處理模式，其依賴語音知覺顯著性較高的韻母協助詞彙提取。整體而言，DLD兒童音韻處理歷程較無效率，顯現出詞彙提取困難。綜上推論，建議教學與臨床治療需重視DLD兒童詞彙提取與音韻處理能力之評估與訓練。</p> <p> </p><p>Phonological priming with cross-modal picture-word interference task was used to in-vestigate the phonological processing in children with and without developmental language disorder (DLD). Sixteen children with DLD aged 4 to 6 years and 11 months, and 16 gender- and age-matched children with typical development (TD) were recruited. The target words were paired with 6 types of phonological primes (identical, syllable-related, onset-related, rhyme-related, tone-related, unrelated), and primes were presented 150ms before (SOA -150), simultaneously (SOA 0), or 150ms after (SOA +150) the target. Results showed that (1) the TD group performed faster and more accurately than the DLD group; (2) both groups demonstrated syllable priming and lack tone priming at all SOAs, which suggests children selected a syllable frame in the lexical access process and the contribution of tone is limited; (3) the primary differences between these two groups were at sub-syllabic level. The DLD group exhibited rhyme priming at SOA -150 and SOA +150, while the TD group only ex-hibited onset interference at SOA 0. Based on these results, the possible inference was that children with TD may apply Cohort model to perceive incoming phonological information, however, children with DLD may not utilize this manner or they were not mature enough to use it, and their word retrieval process depended on high-saliency rhyme. Overall, the phonological processing in children with DLD was inefficient, and they revealed word re-trieval difficulty. Thus, it is recommended to evaluate and intervene word retrieval and phonological processing in children with DLD.</p> <p> </p>

Syllables are Retrieved before Segments in the Spoken Production of Mandarin Chinese: An ERP Study

Languages may differ in terms of the functional units of word-form encoding used in spoken word production. It is widely accepted that segments are the primary units used in Indo-European languages. However, it is controversial what the functional units (syllables or segments) in Chinese spoken word production are. In the present study, Mandarin Chinese speakers named pictures while ignoring distractor words presented simultaneously, which shared atonal syllables, bodies or rhymes, or were unrelated with the name of the target pictures. Behavioral results showed that naming latencies in the 3 phonologically-related conditions were significantly shorter than those associated with the unrelated condition. EEG data indicated that the syllable-related condition modulated event-related potentials (ERPs) in a time window of 320–500 ms, the body-related condition modulated ERPs from 370–420 ms, while the rhyme-related condition modulated ERPs from 400–450 ms. The starting points for evident syllable, body, and rhyme priming effects were 322 ms, 368 ms, and 408 ms (by the Guthrie & Buchwald method) or 340 ms, 372 ms and 403 ms (by the jackknife procedure), respectively. Our findings provide a relative temporal course of syllable and segment encoding in Chinese spoken naming: Syllables are retrieved before segments, and constitute the primary processing units during the early stage of word-form encoding. Furthermore, segments and their order are retrieved incrementally from left to right when producing Chinese spoken words.

Cohort and Rhyme Priming Emerge from the Multiplex Network Structure of the Mental Lexicon

Complex networks recently opened new ways for investigating how language use is influenced by the mental representation of word similarities. This work adopts the framework of multiplex lexical networks for investigating lexical retrieval from memory. The focus is on priming, i.e., exposure to a given stimulus facilitating or inhibiting retrieval of a given lexical item. Supported by recent findings of network distance influencing lexical retrieval, the multiplex network approach tests how the layout of hundreds of thousands of word-word similarities in the mental lexicon can lead to priming effects on multiple combined semantic and phonological levels. Results provide quantitative evidence that phonological priming effects are encoded directly in the multiplex structure of the mental representation of words sharing phonemes either in their onsets (cohort priming) or at their ends (rhyme priming). By comparison with randomised null models, both cohort and rhyming effects are found to be emerging properties of the mental lexicon arising from its multiplexity. These priming effects are absent on individual layers but become prominent on the combined multiplex structure. The emergence of priming effects is displayed both when only semantic layers are considered, an approximated representation of the so-called semantic memory, and when semantics is enriched with phonological similarities, an approximated representation of the lexical-auditory nature of the mental lexicon. Multiplex lexical networks can account for connections between semantic and phonological information in the mental lexicon and hence represent a promising modelling route for shedding light on the interplay between multiple aspects of language and human cognition in synergy with experimental psycholinguistic data.

Phonological and semantic priming in American Sign Language: N300 and N400 effects

ABSTRACTThis study investigated the electrophysiological signatures of phonological and semantic priming in American Sign Language (ASL). Deaf signers made semantic relatedness judgments to pairs of ASL signs separated by a 1300 ms prime-target SOA. Phonologically related sign pairs shared two of three phonological parameters (handshape, location, and movement). Target signs preceded by phonologically related and semantically related prime signs elicited smaller negativities within the N300 and N400 windows than those preceded by unrelated primes. N300 effects, typically reported in studies of picture processing, are interpreted to reflect the mapping from the visual features of the signs to more abstract linguistic representations. N400 effects, consistent with rhyme priming effects in the spoken language literature, are taken to index lexico-semantic processes that appear to be largely modality independent. Together, these results highlight both the unique visual-manual nature of sign languages and the linguistic processing characteristics they share with spoken languages.

Prenatal Cocaine Exposure Impacts Language and Reading Into Late Adolescence: Behavioral and ERP Evidence

ABSTRACTExtant research documents impaired language among children with prenatal cocaine exposure (PCE) relative to nondrug exposed (NDE) children, suggesting that cocaine alters development of neurobiological systems that support language. The current study examines behavioral and neural (electrophysiological) indices of language function in older adolescents. Specifically, we compare performance of PCE (N = 59) and NDE (N = 51) adolescents on a battery of cognitive and linguistic assessments that tap word reading, reading comprehension, semantic and grammatical processing, and IQ. In addition, we examine event related potential (ERP) responses in in a subset of these children across three experimental tasks that examine word level phonological processing (rhyme priming), word level semantic processing (semantic priming), and sentence level semantic processing (semantic anomaly). Findings reveal deficits across a number of reading and language assessments, after controlling for socioeconomic status and exposure to other substances. Additionally, ERP data reveal atypical orthography to phonology mapping (reduced N1/P2 response) and atypical rhyme and semantic processing (N400 response). These findings suggest that PCE continues to impact language and reading skills into the late teenage years.

Auditory morphological processing: Evidence from phonological priming

Using an auditory lexical decision task, we find evidence of a facilitatory priming effect for morphologically complex targets (e.g., snow-ed) preceded by primes which rhyme with the target’s stem (e.g., dough). By using rhyme priming, we are able to probe for morphological processing in a way that avoids confounds arising from semantic relatedness that are inherent to morphological priming (snow/snow-ed). Phonological control conditions (e.g., targets code and grove for prime dough) are used to rule out alternative interpretations of the effect that are based on partial rhyme or phonological embedding of the stem. The findings provide novel evidence for an independent morphological component in lexical processing and demonstrate the utility of rhyme priming in probing morphological representation.

Interlanguage dynamics and lexical networks in nonnative L2 signers of ASL: cross-modal rhyme priming

This study investigated the structure of the bimodal bilingual lexicon. In the cross-modal priming task nonnative sign language learners heard an English word (e.g.,keys) and responded to the lexicality of a signed target: an underlying rhyme (e.g.,cheese) or a sign neighbor of that word (e.g.,paper). The results indicated that rhyme words were retrieved more quickly and the L2 neighbors were faster for beginner learners. An item analysis also indicated that semantics did not facilitate neighbor retrieval and high frequency signs were retrieved more quickly. The AX discrimination task showed that learners focus on handshape and movement parameters and discriminate equally. The interlanguage dynamics play an important role in which phonological parameters are used and the spread of activation over time. A nonselective, integrated model of the bimodal bilingual lexicon is proposed such that lateral connections are weakened over time and handshape parameter feeds most of the activation to neighboring signs as a function of system dynamics.

Lexicality drives audio-motor transformations in Broca’s area

Broca’s area is classically associated with speech production. Recently, Broca’s area has also been implicated in speech perception and non-linguistic information processing. With respect to the latter function, Broca’s area is considered to be a central area in a network constituting the human mirror system, which maps observed or heard actions onto motor programs to execute analogous actions. These mechanisms share some similarities with Liberman’s motor theory, where objects of speech perception correspond to listener’s intended articulatory gestures. The aim of the current series of behavioral, TMS and fMRI studies was to test if Broca’s area is indeed implicated in such audio-motor transformations. More specifically, using a classical phonological rhyme priming paradigm, we investigated whether the role of Broca’s area could be purely phonological or rather, is lexical in nature. In the behavioral baseline study, we found a large priming effect in word prime/target pairs (W–W) and no effect for pseudo-words (PW–PW). Online TMS interference of Broca’s area canceled the priming difference between W–W and PW–PW by enhancing the effects for PW–PW. Finally, the fMRI study showed activation of Broca’s area for W–W pairs, but not for PW–PW pairs. Our data show that Broca’s area plays a significant role in speech perception strongly linked to the lexicality of a stimulus.

Assimilation and Anticipation in Continuous Spoken Word Recognition

English coronal place assimilation is one of many productive phonological processes that change the phonological form of words. It may, for example, cause speakers to pronounce green as something approximating [grin] or [grim] in different contexts. The present work examines how listeners recognize words that have undergone this modification. Current accounts are broadly differentiated by two issues: (1) whether listeners generally recognize words that have undergone word-final, single-feature modification, and (2) how context effects in the perception of assimilated speech are interpreted. Experiment 1 employs form priming to demonstrate that listeners tolerate single-feature mismatch resulting from both phonologically plausible and phonologically implausible word form modification when recognizing words heard in context. Experiments 2 and 3 employ phoneme monitoring and negative rhyme priming paradigms, respectively, to demonstrate that listeners use assimilation to anticipate upcoming context. Evidence for anticipation is contrasted with claims that listeners use context to regressively infer the underlying form of place-assimilated segments.

Phonological priming in children's picture naming.

Two experiments examined phonological priming in children and adults, using a cross-modal picture-word interference task. Pictures of familiar objects were presented on a computer screen, while interfering words (IWs) were presented over headphones. In terms of their relation to target pictures, IWs were either phonologically related, unrelated, neutral (the word go), or identical. Ninety children (30 aged 4;11 to 5;11, 30 aged 6;11 to 7;11, and 30 aged 9;5 to 11;9) and 30 adults were instructed to name the pictures as quickly as possible while ignoring the IWs. In Experiment 1, related IWs shared onset consonants with the names of the pictures. Across ages, participants named pictures faster with related IWs than with unrelated IWs. In Experiment 2, related IWs rhymed with the targets. Here, only the youngest children (five to seven-year-olds) named pictures faster with related IWs than with unrelated IWs. The results indicate that priming effects reach a peak during a time when articulatory information is being consolidated in the output phonological buffer. The disappearance of the rhyme priming effect with age may reflect the gradual emergence of the onset as an organizing structure in speech production. This increased prominence of the onset can be viewed as one component of a just-in-time, incrementalist approach to speech production that allows adults to speak more fluently than children.

The Mapping from Sound Structure to the Lexicon in Aphasia: Evidence from Rhyme and Repetition Priming

Two studies were conducted to explore the hypothesis that Broca's and Wernicke's aphasics have deficits arising from the processes involved in activating the lexicon from phonological form. The first study explored whether phonologically similar lexical entries differing only in their initial consonants show “rhyme priming.” Results revealed that Broca's aphasics failed to show facilitation when the target was identical to the prime (i.e. identity priming) and they showed significant inhibition when targets were preceded by rhyming words. Wernicke's aphasics showed a pattern of results similar to that of normal subjects, i.e., identity priming and rhyme priming as well as significantly slower reaction-times in the rhyming condition compared to the identity condition. The second study investigated form-based repetition priming in aphasic patients at a number of intervals including when no other stimuli intervened between repeated stimuli (0 lag) or when 4, 8, or 12 stimuli intervened. Results showed that, unlike old normal subjects who showed repetition priming for both words and nonwords, both Broca's and Wernicke's aphasics showed repetition priming for word targets only. Moreover, in contrast to old normal subjects who showed a greater magnitude of priming at 0 lag for word targets, neither Broca's aphasics or Wernicke's aphasics showed priming at 0 lag. Implications of these findings are considered with respect to the hypotheses that Broca's and Wernicke's aphasics have deficits in the nature of the activation patterns within the lexicon itself and in auditory (working) memory.

Masked Orthographic and Phonological Priming in Visual Word Recognition and Naming: Cross-Task Comparisons

The effects of briefly presented, masked, and orthographically and/or phonologically related nonword primes on the recognition of subsequently presented target words were investigated in different experimental tasks. Robust effects of orthographic and phonological priming were observed in both the lexical decision and the perceptual identification tasks, with no such effects appearing in the word naming task, except for orthographic priming effects at the shortest prime exposures. Further investigation of this marked dissociation across experimental tasks showed that word naming is particularly sensitive to shared onsets in the masked priming paradigm and that robust rhyme priming does occur when primes and targets have different onsets. The lexical decision task, on the other hand, showed priming effects independently of whether prime and targets shared onsets. These results are discussed within the framework of a bimodal interactive activation model of visual word recognition and naming.

Inhibition of naming by rhyming primes.

The priming effects of graphemically similar (e.g., HOSE) and graphemically dissimilar (e.g., ROWS) rhymes on the naming of target words (NOSE) were examined at prime-target stimulus onset asynchronies (SOA) of 36, 70, and 250 msec. A four-field presentation procedure was used of mask-prime-mask-target. The effects of rhyme primes were measured relative to those of nonrhyming control primes (CHEF, DISH) that matched the rhymes in frequency and length and shared no letters in the same positions. At SOAs of 36 and 70 msec, rhyme priming was inhibitory and equal for graphemically similar and graphemically dissimilar rhymes. At SOA = 250 msec, rhyme priming was insignificant with a tendency toward facilitation. The results are discussed in the context of (1) contrasting effects of complete versus partial phonological overlap within a prime-target pair, and (2) the hypothesis that phonological codes stabilize fastest and provide, therefore, the earliest and major constraint on word recognition.

Perceptual distance and competition in lexical access.

Two experiments use rhyme priming techniques to explore the decision space for lexical access. The 1st experiment, using intramodal (auditory-auditory) priming, covaried the phonological distance of a spoken rhyme prime (e.g., pomato) from its source word (e.g., tomato) with the presence or absence of close lexical competitors. The results showed strong effects of phonological distance and no significant effects of competitor environment. The 2nd experiment, using ambiguous rhyme primes in a cross-modal (auditory-visual) priming task, showed that phonetically ambiguous primes could fully match their source words, but only in the appropriate lexical environment. The results support a view of lexical access in which the listener's perceptual experience is based on strict requirements for a bottom-up match with the speech input, and in which competitor environment does not directly modulate the on-line goodness-of-fit computation.

Rhyme Priming in Aphasia: The Role of Phonology in Lexical Access

The present experiment was conducted to explore the facilitory effects of rhyme in lexical processing in brain-damaged individuals. Normal subjects and non-fluent and fluent aphasic subjects performed auditory lexical decision and rhyme judgement tasks, in which prime-target pairs were phonologically related (either identical or rhyming) or unrelated. Results revealed rhyme facilitation of lexical decisions to real-word targets for normal and non-fluent aphasic subjects; for fluent aphasic subjects, results were equivocal. In the rhyme judgement task, facilitory effects of rhyme were found for all three groups with real-word targets. None of the groups showed clear rhyme facilitation effects with non-word targets in either task. Findings are discussed with reference to the role of phonology in lexical processing in normal and aphasic populations.

Rhyme priming of pictures and words: A lexical activation account.

Orthographically/phonologically related primes have typically been found to facilitate processing of target words. This phenomenon is usually explained in terms of spreading activation between nodes for orthographically/phonologically similar words in lexical memory. The phenomenon was explored in a series of studies involving the manipulations of prime and target type (word or picture) and prime and target task (naming or categorization). Generally, the results support the lexical activation explanation. Named primes, which activate lexical memory, facilitate processing in all target tasks involving lexical access (word and picture naming and word categorization), independent of prime type. Categorized primes show the expected Prime Type x Relatedness interaction with word primes, which activate lexical memory, producing much more facilitation than picture primes. Finally, unlike in semantic priming studies, increased depth of processing of a word prime decreased the size of the priming effects. Apparently, initial activation levels in lexical memory are not maintained when semantic processing of the prime is required. One of the major issues being addressed by cognitive psychologists is how context affects the processing of new information. Especially fruitful in this regard has been the priming paradigm first reported by Meyer and Schvaneveldt (1971). In a typical priming task, two stimuli are presented sequentially. The first, or prime, stimulus establishes a particular context. Empirically, the question is whether this context affects processing of the second, or target, stimulus.

Phonological code activation during listening.

Rhyme priming to visually dissimilar rhymes (e.g., eight-late) was used in a lexical decision task to investigate the access and maintenance of speech-based codes in sentence comprehension. One member of the rhyme pair was embedded in a sentence and the other was presented visually for lexical decision. Rhyme priming obtained when the prime and target were separated by four but not by seven intervening words, suggesting that the phonological code for the word was initially accessed and then rapidly decayed.
