Dialect Recognition via Lexical Processing: Is It a Viable Litmus Test?

For decades, linguists have been working to formulate an objective means of distinguishing dialects from languages, but dialect recognition has largely remained a subjective enterprise. Only recently have some studies proposed a processing-based psycholinguistic approach toward dialect recognition. These studies argued that dialect words are stored as a co-dependent representation, not as an independent representation of the words of bilingual speakers. Based on these studies, we investigated the lexical selection and processing mechanisms of bilingual and bidialectal speakers of two understudied languages, Oromo and Amharic, using the picture–word interference paradigm. We found independent lexical representations for both the bilingual and the bidialectal groups, which implies the involvement of the same cognitive mechanisms in both language and dialect processing. Thus, we argue that bidialectal speakers have flexible lexical representation and selection mechanisms that are dependent on the speakers’ previous language experience. Here, we propose a dynamic lexical selection model that accommodates diverse dialect ecologies.

The multiple phonological activation in Chinese spoken word production: An ERP study supporting cascaded model

A central issue in spoken word production concerns how activation is transmitted from semantic to phonological levels. The current study investigated the issue of seriality and cascadedness in Chinese spoken word production, via the combined semantic blocked paradigm (with homogeneous and heterogeneous blocks) and picture-word interference paradigm (with phonologically related, mediated and unrelated distractors). Naming latencies data showed a mediated effect via comparing mediated and unrelated distractors in homogeneous blocks, a phonological facilitation effect via comparing phonologically related and unrelated distractors in homogeneous and heterogeneous blocks, and a semantic interference effect via comparing homogeneous and heterogeneous blocks. Critically, cluster-based permutation test of ERP data demonstrated a mediated effect around 266-326ms and an overlapped pattern of semantic interference effect around 264-418ms and phonological facilitation effect around 210-310ms in homogeneous or around 236-316ms in heterogeneous blocks. These findings indicated that speakers activate phonological nodes of non-targets, and present a cascadedness pattern of the transmission from semantics to phonology in Chinese spoken production. The present study sheds new insight on the neural correlates of semantic and phonological effects, and provides behavioral and electrophysiological evidences for the cascaded model within a theoretical framework of lexical competition in speech production.

The Scope of Phonological Encoding Plans for Stutterers

The picture-word interference paradigm was used to examine the scope of phonological encoding plans of stutterers using two indicators: naming latency and error rate. The experiment requires participants to generate sentences containing three image names in their spoken language, while visually presenting interfering words and manipulating their phonetic correlations. The results showed that stutterers only had a phonological facilitation effect on the first noun, and there was no phonological facilitation effect or lexical interference effect on the second and third nouns, indicating that the scope of the stutterer’s phonological encoding plan was the first noun.

A cautionary note on the studies using the picture-word interference paradigm: the unwelcome consequences of the random use of "in/animates".

The picture-word interference (PWI) paradigm allows us to delve into the process of lexical access in language production with great precision. It creates situations of interference between target pictures and superimposed distractor words that participants must consciously ignore to name the pictures. Yet, although the PWI paradigm has offered numerous insights at all levels of lexical representation, in this work we expose an extended lack of control regarding the variable animacy. Animacy has been shown to have a great impact on cognition, especially when it comes to the mechanisms of attention, which are highly biased toward animate entities to the detriment of inanimate objects. Furthermore, animate nouns have been shown to be semantically richer and prioritized during lexical access, with effects observable in multiple psycholinguistic tasks. Indeed, not only does the performance on a PWI task directly depend on the different stages of lexical access to nouns, but also attention has a fundamental role in it, as participants must focus on targets and ignore interfering distractors. We conducted a systematic review with the terms "picture-word interference paradigm" and "animacy" in the databases PsycInfo and Psychology Database. The search revealed that only 12 from a total of 193 PWI studies controlled for animacy, and only one considered it as a factor in the design. The remaining studies included animate and inanimate stimuli in their materials randomly, sometimes in a very disproportionate amount across conditions. We speculate about the possible impact of this uncontrolled variable mixing on many types of effects within the framework of multiple theories, namely the Animate Monitoring Hypothesis, the WEAVER++ model, and the Independent Network Model in an attempt to fuel the theoretical debate on this issue as well as the empirical research to turn speculations into knowledge.

The Effect of Semantic Context on Lexical Access in Children With and Without Developmental Language Disorder

Objectives: Lexical access problems are one of the limitations observed in children with developmental language disorders during the initial years of schooling. Semantic context has a powerful influence on lexical access. The cross-modal visual-auditory picture-word interference paradigm is a method for studying adults and children's lexical access. Because few studies have examined lexical access in Persian-speaking children, the present study aimed to investigate the effect of different semantic contexts on lexical access in children with and without developmental language disorder. Methods: In this experimental study, 20 children aged 7-9 years with developmental language disorders and 20 age-matched peers were recruited according to the inclusion and exclusion criteria. At first, the picture-word interference paradigm was prepared. In so doing, 16 common pictures of objects paired with four auditory interfering words (related verb, related noun, unrelated verb, and unrelated noun) were presented to the children in a silent condition to determine their naming accuracy and latency. The DMDX software calculated the naming latency. The percentage of correct names also calculated naming accuracy. Results: Naming latencies were significantly faster in children without language disorders (P≤0.05). In addition, a reliable interference effect was found. According to the results, naming latencies were significantly faster for related verb distractors than unrelated verbs and related noun distractors (P<0.05). In addition, a significant difference was observed between the silent and interference conditions regarding the naming accuracy. However, accuracy was not affected by distractors. Discussion: Different semantic contexts affect lexical access differently in children. These differences cause semantic relatedness between verbs and nouns in lexical networks. The present study findings indicate that lexical knowledge and semantic relatedness are lower in children with developmental language disorders than in those with typical language development. These results can be useful for future studies and interventions on lexical access in children with and without language disorders.

Lexical Access in Preschool Mandarin-Speaking Children With Cochlear Implants.

Children with cochlear implants (CIs) have less experience accessing spoken language. Mandarin Chinese uses pitch information to contrast word meaning, and the signal that the CI devices provide is degraded. Thus, Mandarin-speaking children with CIs may face more challenges in the development of language skills. This study examines preschool Mandarin-speaking children's performance in lexical access. We hypothesized that children with CIs and their peers with normal hearing (NH) have comparable naming ability, but they process phonological or semantic information differently. Twenty children with CIs and 20 age-matched children with NH were tested. The cross-modal visual-auditory picture-word interference paradigm was applied. The distractor was either phonologically related (mao55 cat -mao51 hat), semantically related (mao55 cat -shu214 mouse) or unrelated (mao55 cat -zhi214 paper) to the target, and it was aurally presented at four different points in time relative to the picture. Accuracy was compared between the two groups to tap into the children's naming abilities, and reaction time was analyzed to examine the effects of phonological and semantic information. No group difference in accuracy was found. The phonologically related distractors led to significantly higher accuracy scores and shorter reaction times, whereas the semantically related distractors did not. Unlike the NH group, the CI group did not respond significantly faster or slower in phonologically related condition when the distractor and picture occurred simultaneously. Finally, the CI group made overall quicker responses than the NH group. Children with CIs are as successful as children with NH in word retrieval and production, and the two groups both show phonological priming effect and lack semantic effect. However, children with CIs do not process phonological information as early as their NH peers, and they may be more tasks directed and hence make quicker responses.

The left inferior frontal gyrus and the resolution of unimodal vs. cross-modal interference in speech production: A transcranial direct current stimulation study

Most neurobiological models of spoken word production propose that multiple lexical candidates are activated in left posterior temporal cortex during word retrieval. Some accounts also propose a role for the left inferior frontal gyrus (LIFG) in selecting the correct word from among these candidates. Evidence for both proposals has come from the picture-word interference (PWI) paradigm, in which participants name pictures (e.g., RABBIT) while ignoring a distractor word. Categorically related distractors (e.g., horse -RABBIT) slow naming latencies compared to unrelated words (e.g., violin -RABBIT), an effect known as semantic interference, whereas congruent distractors (e.g., rabbit -RABBIT) facilitate naming, but the precise conditions in which these effects occur remain a matter of debate. Although the neuroimaging evidence for left temporal cortex engagement in this paradigm is robust, the evidence for LIFG involvement is more equivocal, particularly for semantic interference. A key factor distinguishing LIFG involvement in neuroimaging studies is distractor modality , i.e., activity is more consistently reported for auditory distractors. We therefore applied online anodal transcranial Direct Current Stimulation (atDCS) to LIFG and left posterior temporal cortex in a three-way, cross-over, sham-controlled PWI paradigm involving either written (Experiment 1) or auditory (Experiment 2) distractors. Surprisingly, compared to sham, atDCS over posterior temporal cortex significantly slowed the congruent facilitation effect with written distractors, but did not modulate the semantic interference effect, while atDCS to LIFG did not significantly influence either effect. We also failed to observe any significant modulatory effects of atDCS with auditory distractors. The present results only partially support left temporal lobe engagement during PWI and provide no evidence for LIFG involvement. We recommend future PWI studies systematically investigate different electrode montages in tDCS protocols. • Stimulation to left posterior middle temporal gyrus modulated picture naming with written congruent distractor words. • Stimulation to left posterior middle temporal gyrus did not modulate picture naming with auditory distractors. • Stimulation to left inferior frontal gyrus did not modulate picture naming with written or auditory distractors.

Language dominance influences bilingual lexical selection quantitatively but not qualitatively in language production: Evidence from Chinese-English bilinguals

Previous research on bilingual lexical selection has mainly investigated the influence of the dominant first language (L1) on the speech production of the non-dominant second language (L2). However, research in the reverse direction is quite rare. Here we examined the influence in both directions using a bilingual picture-word interference (PWI) paradigm, where Chinese-English bilinguals named pictures in one language while ignoring distractors presented in another language. In both L1 and L2 naming, naming times were longer when distractors were semantically related to the picture names than when they were unrelated, resulting in a between-language semantic interference effect. In contrast, naming times were shorter when distractors were translations of the picture names than when they were unrelated, resulting in a translation facilitation effect. The results suggested that the mechanism of lexical selection in language production was in line with the within-language competition theory, showing no qualitative differences in the mechanism between L1 and L2. At the same time, the semantic interference effect sizes were not significantly different in L1 and L2 production, but the translation facilitation effect size was significantly larger in L2 production than in L1 production, indicating there exist quantitative differences in the mechanism of lexical selection between L1 and L2. A computational model was constructed to simulate naming performance and confirmed the accuracy of the within-language competition view in L1 and L2 lexical selection for Chinese-English bilinguals. We concluded that language dominance influences bilingual lexical selection quantitatively but not qualitatively in bilingual language production.

When words collide: Bayesian meta-analyses of distractor and target properties in the picture-word interference paradigm.

In the picture-word interference paradigm, participants name pictures while ignoring a written or spoken distractor word. Naming times to the pictures are slowed down by the presence of the distractor word. The present study investigates in detail the impact of distractor and target word properties on picture naming times, building on the seminal study by Miozzo and Caramazza. We report the results of several Bayesian meta-analyses based on 26 datasets. These analyses provide estimates of effect sizes and their precision for several variables and their interactions. They show the reliability of the distractor frequency effect on picture naming latencies (latencies decrease as the frequency of the distractor increases) and demonstrate for the first time the impact of distractor length, with longer naming latencies for trials with longer distractors. Moreover, distractor frequency interacts with target word frequency to predict picture naming latencies. The methodological and theoretical implications of these findings are discussed.

Picture-word interference in language production studies: Exploring the roles of attention and processing times.

The picture-word interference paradigm (participants name target pictures while ignoring distractor words) is often used to model the planning processes involved in word production. The participants' naming times are delayed in the presence of a distractor (general interference). The size of this effect depends on the relationship between the target and distractor words. Distractors of the same semantic category create more interference (semantic interference), and distractors overlapping in phonology create less interference (phonological facilitation). The present study examined the relationships between these experimental effects, processing times, and attention in order to better understand the cognitive processes underlying participants' behavior in this paradigm. Participants named pictures with a superimposed line of Xs, semantically related distractors, phonologically related distractors, or unrelated distractors. General interference, semantic interference, and phonological facilitation effects were replicated. Distributional analyses revealed that general and semantic interference effects increase with naming times, while phonological facilitation decreases. The phonological facilitation and semantic interference effects were found to depend on the synchronicity in processing times between the planning of the picture's name and the processing of the distractor word. Finally, electroencephalographic power in the alpha band before stimulus onset varied with the position of the trial in the experiment and with repetition but did not predict the size of interference/facilitation effects. Taken together, these results suggest that experimental effects in the picture-word interference paradigm depend on processing times to both the target word and distractor word and that distributional patterns could partly reflect this dependency.

The mechanisms underlying grammatical gender selection in language production: A meta-analysis of the gender congruency effect

Grammatical gender retrieval during language production has been largely addressed through the picture-word interference (PWI) paradigm, with the aim of capturing the so-called gender congruency effect (GCE). In the PWI paradigm, participants name target pictures while ignoring superimposed written distractor nouns. The GCE shows faster responses when target and distractor nouns share the same gender than when gender differs. Yet, the locus of this effect is not clear: it might be either due to the selection of a determiner or due to the selection of a gender node at the lemma level, which may be primed or delayed by competition. Importantly, many of those who argue that the GCE is not a genuine effect of gender conclude that gender is a feature that is retrieved automatically. Such a claim is controversial since the PWI paradigm has been seen as too complex and perhaps not sensitive enough to capture small effects. Besides, for Romance languages, mixed results draw a complex picture with effects occurring mainly in the opposite direction, i.e., a gender incongruency effect (GIE). In the present study, we conducted a meta-analysis of the 18 studies that have addressed this issue. The results confirm the existence of the GCE as a determiner effect in Germanic/Slavic languages, while little support is found for the GIE in Romance languages. Nevertheless, we argue that the absence of gender effects in Germanic and Slavic languages within the PWI paradigm cannot be taken as evidence of an absence of priming/competition during gender selection and thus as evidence of an automatic selection of gender. Parametric replication of previous studies, especially those featuring bound morphemes, together with the use of other measuring techniques such as event related potentials are suggested as a way forward.

Picture-Word Interference Effects Are Robust With Covert Retrieval, With and Without Gamification.

The picture-word interference (PWI) paradigm has been used to investigate the time course of processes involved in word retrieval, but is challenging to implement online due to dependence on measurements of vocal reaction time. We performed a series of four experiments to examine picture-word interference and facilitation effects in a form of covert picture naming, with and without gamification. A target picture was accompanied by an audio word distractor that was either unrelated, phonologically-related, associatively-related, or categorically-related to the picture. Participants were instructed to judge whether the name of the target picture ended in the phoneme assigned to the block by pressing corresponding keys as quickly and accurately as possible. Experiments 1 and 2 successfully replicated categorical interference and phonological facilitation effects at different optimal stimulus-onset-asynchronies (SOAs) between words and pictures. Experiment 3 demonstrated that a key gamification feature (collecting coins) motivated faster speed at the expense of accuracy in the gamified vs. experimental format of the task. Experiment 4 adopted the optimal SOAs and verified that the gamification reveals expected interference and facilitation effects despite the speed-accuracy tradeoff. These studies confirmed that categorical interference occurs earlier than phonological facilitation, while both processes are independent from articulation and inherent to word retrieval itself. The covert PWI paradigm and its gamification have methodological value for neuroimaging studies in which articulatory artifacts obscure word retrieval processes, and may be developed into potential online word-finding assessments that can reveal word retrieval difficulties with greater sensitivity.

Internet-based language production research with overt articulation: Proof of concept, challenges, and practical advice

Language production experiments with overt articulation have thus far only scarcely been conducted online, mostly due to technical difficulties related to measuring voice onset latencies. Especially the poor audiovisual synchrony in web experiments (Bridges et al. 2020) is a challenge to time-locking stimuli and participants’ spoken responses. We tested the viability of conducting language production experiments with overt articulation in online settings using the picture–word interference paradigm – a classic task in language production research. In three pre-registered experiments (N = 48 each), participants named object pictures while ignoring visually superimposed distractor words. We implemented a custom voice recording option in two different web experiment builders and recorded naming responses in audio files. From these stimulus-locked audio files, we extracted voice onset latencies offline. In a control task, participants classified the last letter of a picture name as a vowel or consonant via button-press, a task that shows comparable semantic interference effects. We expected slower responses when picture and distractor word were semantically related compared to unrelated, independently of task. This semantic interference effect is robust, but relatively small. It should therefore crucially depend on precise timing. We replicated this effect in an online setting, both for button-press and overt naming responses, providing a proof of concept that naming latency – a key dependent variable in language production research – can be reliably measured in online experiments. We discuss challenges for online language production research and suggestions of how to overcome them. The scripts for the online implementation are made available.

Of Beavers and Tables: The Role of Animacy in the Processing of Grammatical Gender Within a Picture-Word Interference Task.

Grammatical gender processing during language production has classically been studied using the so-called picture-word interference (PWI) task. In this procedure, participants are presented with pictures they must name using target nouns while ignoring superimposed written distractor nouns. Variations in response times are expected depending on the congruency between the gender values of targets and distractors. However, there have been disparate results in terms of the mandatory character of an agreement context to observe competitive gender effects and the interpretation of the direction of these effects in Romance languages, this probably due to uncontrolled variables such as animacy. In the present study, we conducted two PWI experiments with European Portuguese speakers who were asked to produce bare nouns. The percentage of animate targets within the list was manipulated: 0, 25, 50, and 100%. A gender congruency effect was found restricted to the 0% list (all targets were inanimate). Results support the selection of gender in transparent languages in the absence of an agreement context, as predicted by the Gender Acquisition and Processing (GAP) hypothesis (Sá-Leite et al., 2019), and are interpreted through the attentional mechanisms involved in the PWI paradigm, in which the processing of animate targets would be favored to the detriment of distractors due to biological relevance and semantic prioritization.

Adaptation of a semantic picture-word interference paradigm for future language mapping with transcranial magnetic stimulation: A behavioural study

Neuro-navigated transcranial magnetic stimulation (TMS) helps to identify language-related cortical regions prior to brain tumour surgery. We adapted a semantic picture-word interference (PWI) paradigm from psycholinguistics to high-resolution TMS language mapping which prospectively can be used to specifically address the level of semantic processing. In PWI, pictures are presented along with distractor words which facilitate or inhibit the lexical access to the picture name. These modulatory effects of distractors can be annihilated in language-sensitive areas by the inhibitory effects of TMS on language processing. The rationale here is to observe the distractor effect without active stimulation and then to observe presumably its elimination by interference of the TMS stimulation. The special requirements to use PWI in this setting are (1) identifying word material for accelerating reliably naming latencies, choosing (2) the ideal presentation modality, and (3) the appropriate timing of distractor presentation. These are then controlled in real TMS language mapping. To adapt a semantic PWI naming paradigm for TMS application we employed 30 object-pictures in spoken German language. Part-whole associative semantic related or unrelated distractors were presented in two experiments including 15 healthy volunteers each, once auditorily and once visually. Data analysis across the entire stimulus set revealed a trend for facilitation in the visual condition, whereas no effects were observed for auditory distractors. In a sub-set, we found a significant facilitation effect for visual semantic distractors. Thus, with this study we provide a well-controlled item set for future studies implementing effective TMS language mapping applying visual semantic PWI.

Selective activation of language specific structural representations: Evidence from extended picture-word interference

How do bilingual speakers represent and use information that guides the assembly of the words into phrases and sentences (i.e., sentence structures) for languages that have different word orders? Cross-language syntactic priming effects provide mixed evidence on whether bilinguals access sentence structures from both languages even when speaking just one. Here, we compared English monolinguals, Korean-immersed Korean-English bilinguals, and English-immersed Korean-English bilinguals while they produced noun phrases (“the lemon below the lobster”), which have different word orders in English and Korean (the Korean translation word order is [lobster][below][lemon]). We examined when speakers plan each noun using an extended picture-word interference paradigm, by measuring articulation times for each word in the phrase with either the distractor word “apple” (which slows the planning of “lemon”) or “crab” (which slows the planning of “lobster”). Results suggest that for phrases that are different in linear word order across languages, bilinguals only access the sentence structure of the one language they are actively speaking at the time, even when switching languages between trials.

Morphological facilitation and semantic interference in compound production: An ERP study

This study investigates the production of nominal compounds (Experiment 1) and simple nouns (Experiment 2) in a picture-word interference (PWI) paradigm to test models of morpho-lexical representation and processing. The continuous electroencephalogram (EEG) was registered and event-related brain potentials [ERPs] were analyzed in addition to picture-naming latencies. Experiment 1 used morphologically and semantically related distractor words to tap into different pre-articulatory planning stages during compound production. Relative to unrelated distractors, naming was speeded when distractors corresponded to morphemes of the compound (sun or flower for the target sunflower), but slowed when distractors were from the same semantic category as the compound (tulip ➔ sunflower). Distractors from the same category as the compound's first constituent (moon ➔ sunflower) had no influence. The diverging effects for semantic and morphological distractors replicate results from earlier studies. ERPs revealed different effects of morphological and semantic distractors with an interesting time course: morphological effects had an earlier onset. Comparable to the naming latencies, no ERP effects were obtained for distractors from the same semantic category as the compound's first constituent. Experiment 2 investigated the effectiveness of the latter distractors, presenting them with pictures of the compounds' first constituents (e.g., moon ➔ sun). Interference was confirmed both behaviorally and in the ERPs, showing that the absence of an effect in Experiment 1 was not due to the materials used. Considering current models of speech production, the data are best explained by a cascading flow of activation throughout semantic, lexical and morpho-phonological steps of speech planning.

Classifiers in Mandarin Chinese: Behavioral and electrophysiological evidence regarding their representation and processing

In Chinese, when objects are named with their quantity, a numeral classifier must be inserted between the quantifier and the noun to produce a grammatically correct quantifier + classifier + noun phrase. In this study, we adopted the picture-word interference paradigm to examine participants’ naming latencies for multiple objects and their electroencephalogram in four conditions by manipulating two factors, i.e. semantic relatedness and classifier congruency. Results show that in noun phrase production, naming latencies are significantly longer in classifier-incongruent and semantically related conditions than in classifier-congruent and semantically unrelated conditions. Also, an N400-like effect was observed and found to be stronger in classifier-incongruent and semantically unrelated conditions. Together, the behavioral data and event-related potential analyses suggest that the use of classifiers as lexico-syntactic features in Mandarin Chinese takes place via a competitive selection process in noun phrase production.

Using functional near-infrared spectroscopy to study word production in the brain: A picture-word interference study

This study assessed the usefulness of functional near-infrared spectroscopy (fNIRS) to study word production in the brain. As a test case, we focused on the semantic interference effect (SIE), which has been demonstrated in many behavioral studies and has also been studied using neuroimaging techniques. Experiment 1 examined whether fNIRS can identify neural correlates of the SIE in a cross-modal picture-word interference (PWI) paradigm. Native speakers of Flemish Dutch overtly named pictures in their first language (L1), while ignoring auditory distractor words either categorically related or unrelated to target names. Functional NIRS data were obtained from the bilateral frontal and temporal regions and analyzed with a general linear model. We observed the SIE in the naming latencies and fNIRS detected the SIE in the cortical language network including the inferior frontal gyrus, middle temporal gyrus, and precentral gyrus. Most areas showed a signal increase for the related condition compared with the unrelated condition. Experiment 2 tested whether fNIRS can pinpoint differences in neural activities related to semantic interference as a function of the target language in unbalanced bilinguals. Flemish Dutch-English unbalanced bilinguals therefore performed the same PWI task, but now with a second language (L2) naming condition as a separate block. We observed the SIE behaviorally in both language conditions; the size of the SIE was comparable in each language. FNIRS data indicated several channels showing different levels of sensitivity to the SIE between L1 and L2. Both experiments demonstrated that fNIRS could detect neural correlates of the SIE and target language. We will discuss the potential benefits and methodological concerns of using fNIRS for speech production research.
