Linking Language to Action: Enhancing Preschoolers' Communicative Abilities Within Language Stimulation.

PURPOSE: Children's vocabulary and syntactic skills vary upon school entry in depth and breadth, persistently influencing academic performance, including reading. Enhancing early communicative abilities through multisensory, playful, and conversational experiences is essential and will benefit children's school readiness. This study investigated whether a language-to-action link created during language stimulation, which combines multisensory input, play, and conversation using clay, improves preschoolers' communicative abilities in terms of vocabulary, syntactic, and pragmatic language abilities more than traditional toy-based language stimulation. METHOD: Language skills were examined in a pre- to posttest design in which 43 typically developing participants, ages 3-5 years, were randomly assigned to clay-based (n = 24) or traditional play-based (n = 19) language stimulation for 8 weeks. RESULTS: Receptive and expressive vocabulary knowledge for items introduced in the language stimulation program, mean length of utterance (MLU), and conversational initiations improved for participants in the clay condition, whereas significant language skill growth was not observed for participants in the traditional play-based stimulation condition with toys. CONCLUSIONS: A language-to-action link is created when children engage with open-ended materials, such as clay, as they craft target objects hands on and step by step, affording additional opportunities for language input and output. Results preliminarily suggest that using open-ended materials may enhance children's communicative abilities in receptive and expressive vocabulary, syntax/MLU, and pragmatics (i.e., conversational initiations) more than prefabricated toy objects during language stimulation.

Visual word recognition in bilinguals: Eye-tracking evidence that L2 proficiency impacts access of L1 phonotactics.

A bilingual's language system is highly interactive. When hearing a second language (L2), bilinguals access native-language (L1) words that share sounds across languages. In the present study, we examine whether input modality and L2 proficiency moderate the extent to which bilinguals activate L1 phonotactic constraints (i.e., rules for combining speech sounds) during L2 processing. Eye-movements of English monolinguals and Spanish-English bilinguals were tracked as they searched for a target English word in a visual display. On critical trials, displays included a target that conflicted with the Spanish vowel-onset rule (e.g., sp a), as well as a competitor containing the potentially-activated 'e' onset (e.g., e gg). The rule violation was processed either in the visual modality (Experiment 1) or audio-visually (Experiment 2). In both experiments, bilinguals with lower L2 proficiency made more eye movements to competitors than fillers. Findings suggest that bilinguals who have lower L2 proficiency access L1 phonotactic constraints during L2 visual word processing with and without auditory input of the constraint-conflicting structure (e.g., spa). We conclude that the interactivity between a bilingual's two languages is not limited to words that share form across languages, but also extends to sub-lexical, rule-based structures.

Individual and Sociolinguistic Differences in Language Background Predict Stroop Performance.

To examine how differences in language experience and sociolinguistic context impact cognitive control, 146 Spanish-English bilingual participants were tested on a non-linguistic Stroop arrows task. Dimensions of language experience included a continuum of L2 proficiency, exposure, age of L2 acquisition, and English receptive vocabulary, along with cognitive non-verbal reasoning. Sociolinguistic context varied with more exposure to Spanish for participants in Southern California (SoCal) than in the Midwest. The task involved perceptual stimulus-stimulus conflict within stimulus features (e.g., right-pointing arrow on the left side of a display). Reaction times to trials where arrow location and direction matched (congruent), mismatched (incongruent), or arrow location was centered (neutral) were used to calculate Stroop (incongruent-congruent), facilitation (neutral-congruent), and inhibition (incongruent-neutral) effects. When examining performance on a continuum of bilingual language experience, individual differences in linguistic background (i.e., L2 proficiency and exposure, receptive vocabulary) and cognitive abilities (i.e., non-verbal reasoning abilities) predicted more efficient performance on the Stroop task. Across sociolinguistic contexts, findings revealed better performance via smaller Stroop and facilitation effects in the Midwest than in SoCal, and no group difference on the inhibition effect. We conclude that research on the cognitive consequences of bilingualism must consider a continuum of language experiences and must be situated in broader naturalistic contexts that take into account the sociolinguistic environments of language use.

First-language influence on second language speech perception depends on task demands.

While listening to non-native speech, second language users filter the auditory input through their native language. We examined how bilinguals perceived second language (L2 English) sound sequences that conflicted with native-language (L1 Spanish) constraints across three experiments with different task demands. We used the L1 Spanish phonotactic constraint (i.e., rule for combining speech sounds) that vowels must precede s+consonant clusters (e.g., Spanish: estricto, "strict"). This L1 Spanish constraint may influence Spanish-English bilinguals' processing of L2 English words such as strict because of a missing initial vowel, as in estrict. We found that the extent to which bilinguals were influenced by the L1 during L2 processing depended on task demands. When metalinguistic awareness demands were low, as in the AX word discrimination task (Experiment 1), cross-linguistic effects were not observed. When metalinguistic awareness demands were high, as in the vowel detection (Experiment 2) and lexical decision (Experiment 3) tasks, response times demonstrated that bilinguals were influenced by the L1 constraint when processing L2 words beginning with an s+consonant. We conclude that bilinguals are cross-linguistically influenced by L1 phonotactic constraints during L2 processing when metalinguistic demands are higher, suggesting that L2 input may be mapped onto L1 sub-lexical representations during perception. These results extend previous research on language co-activation and speech perception by providing a more fine-grained understanding of task demands and elucidating when and where cross-linguistic phonotactic access is present during bilingual comprehension.

Does having a voice disorder hurt credibility?

OBJECTIVE: The purpose of the study was to determine whether listeners were less likely to believe a statement that is produced in an atypical voice, as compared to a typical voice. It was hypothesized that an atypical voice, characterized by abnormal roughness, strain, and pitch, would elicit increased skepticism. This hypothesis was based on previous evidence that there are negative stereotypes against individuals who have a voice disorder, and that increased difficulty processing an utterance can lead to disbelief. METHODS: In Experiment 1, 36 listeners rated obscure trivia statements (such as "the elephant is the only mammal that cannot jump" and "the first public library was opened in Vienna in 1745") as definitely false, probably false, probably true, or definitely true. The statements were produced by a speaker who used their typical voice and simulated an atypical voice (of severe deviance according to the CAPE-V), as well as two additional control speakers with typical voices. Experiment 2 was a replication of Experiment 1 with a new set of 36 listeners and a new set of speakers. In addition, Experiment 2 examined whether reduced credibility was due to negative stereotypes and/or processing difficulty, through questionnaire data and correlation analyses. RESULTS: The results were largely consistent with the hypothesis that statements produced in an atypical voice would be perceived as less credible. In both experiments, the percentage of definitely false ratings was higher for the atypical voice than for the typical voice and control voices, with a large effect size in Experiment 1 and a medium effect size in Experiment 2. Further, Experiment 2 suggested that reduced credibility was due to negative stereotypes but not processing difficulty. CONCLUSION: The current study reveals a social consequence of having a voice disorder, i.e., decreased perceived credibility, with implications for job-related success.

Literature-Based Strategies for Clinical Fellow Mentorship.

In the field of communication sciences and disorders, some research and guidance exist on clinical fellowship supervision for the mentor; however, there is a dearth of literature on clinical fellowship supervision from the perspective of the clinical fellow. This article begins with why the clinical fellowship experience is necessary, and then discusses clinical fellow and mentor expectations and responsibilities, clinical fellow independence, mentor qualities, and issues related to the provision of feedback. The overall goal is to enhance clinical fellow mentors' knowledge base on the clinical fellowship experience through review of current literature on supervision and mentorship.

Cross-linguistic phonotactic competition and cognitive control in bilinguals.

The current study examines the relation between cognitive control and linguistic competition resolution at the sublexical level in bilinguals. Twenty-one Spanish-English bilinguals and 23 English monolinguals completed a non-linguistic Stroop task (indexing inhibitory control) and a linguistic priming/lexical decision task (indexing Spanish phonotactic constraint competition during English comprehension). More efficient Stroop performance (i.e., a smaller Stroop effect) in bilinguals was associated with decreased competition from Spanish phonotactic constraints during English comprehension. This relation was observed when nonword targets overlapped in phonotactic constraints and phonological form with preceding cognate primes (e.g., prime: stable (Spanish: estable)/target: esteriors). Findings suggest a link between non-linguistic cognitive control and co-activation of linguistic structures at the sublexical level in bilinguals.

Phonotactic Constraints Are Activated across Languages in Bilinguals.

During spoken language comprehension, auditory input activates a bilingual's two languages in parallel based on phonological representations that are shared across languages. However, it is unclear whether bilinguals access phonotactic constraints from the non-target language during target language processing. For example, in Spanish, words with s+ consonant onsets cannot exist, and phonotactic constraints call for epenthesis (addition of a vowel, e.g., stable/estable). Native Spanish speakers may produce English words such as estudy ("study") with epenthesis, suggesting that these bilinguals apply Spanish phonotactic constraints when speaking English. The present study is the first to examine whether bilinguals access Spanish phonotactic constraints during English comprehension. In an English cross-modal priming lexical decision task, Spanish-English bilinguals and English monolinguals heard English cognate and non-cognate primes containing s+ consonant onsets or controls without s+ onsets, followed by a lexical decision on visual targets with the /e/ phonotactic constraint or controls without /e/. Results revealed that bilinguals were faster to respond to /es/ non-word targets preceded by s+ cognate primes and /es/ and /e/ non-word targets preceded by s+ non-cognate primes, confirming that English primes containing s+ onsets activated Spanish phonotactic constraints. These findings are discussed within current accounts of parallel activation of two languages during bilingual spoken language comprehension, which may be expanded to include activation of phonotactic constraints from the irrelevant language.

Auditory word recognition across the lifespan: Links between linguistic and nonlinguistic inhibitory control in bilinguals and monolinguals.

Recent research suggests that bilingual experience reconfigures linguistic and nonlinguistic cognitive processes. We examined the relationship between linguistic competition resolution and nonlinguistic cognitive control in younger and older adults who were either bilingual or monolingual. Participants heard words in English and identified the referent among four pictures while eye-movements were recorded. Target pictures (e.g., cab) appeared with a phonological competitor picture (e.g., cat) and two filler pictures. After each eye-tracking trial, priming probes assessed residual activation and inhibition of target and competitor words. When accounting for processing speed, results revealed that age-related changes in activation and inhibition are smaller in bilinguals than in monolinguals. Moreover, younger and older bilinguals, but not monolinguals, recruited similar inhibition mechanisms during word identification and during a nonlinguistic Stroop task. Results suggest that, during lexical access, bilinguals show more consistent competition resolution and recruitment of cognitive control across the lifespan than monolinguals.

Six principles of language development: implications for second language learners.

The number of children growing up in dual language environments is increasing in the United States. Despite the apparent benefits of speaking two languages, children learning English as a second language (ESL) often face struggles, as they may experience poverty and impoverished language input at home. Early exposure to a rich language environment is crucial for ESL children's academic success. This article explores how six evidenced-based principles of language learning can be used to provide support for ESL children.
