Esteban, Reuben H.; Taladngoen, Unaree (2022). Assumptions on Plausible Lexical Distractors in the Redesigned TOEIC Question-Response Listening Test. LEARN Journal: Language Education and Acquisition Research Network, v15 n2 p802-829 Jul-Dec. Distractors in tests are included to divert attention away from correct answers choices. Knowing what types of distractors commonly appear in tests will benefit test takers as they can prepare themselves beforehand. Therefore, this qualitative study was aimed at making assumptions on plausible lexical distractors which are expected to appear in the TOEIC Question-Response listening test. The data under analysis were 300 items from the TOEIC Question-Response listening practice tests published by two internationally well-known publishers. With the aid of thematic analysis, the findings revealed that the three most commonly plausible lexical distractors were repeated words, similar-sounding words, and word associations, followed by homonyms, overlapping words, derivational words, and homophones, respectively. The two least frequently used lexical distractors were synonyms and antonyms. Based on the findings in the present study, the authors suggest integrating both explicit and… [PDF]

Frost, Stephen; Jasinska, Kaja K.; Landi, Nicole; Lau, Airey N. L.; Pugh, Kenneth R.; Shuai, Lan (2021). Functional Connectivity in the Developing Language Network in 4-Year-Old Children Predicts Future Reading Ability. Developmental Science, v24 n2 e13041 Mar. Understanding how pre-literate children's language abilities and neural function relate to future reading ability is important for identifying children who may be at-risk for reading problems. Pre-literate children are already proficient users of spoken language and their developing brain networks for language become highly overlapping with brain networks that emerge during literacy acquisition. In the present longitudinal study, we examined language abilities, and neural activation and connectivity within the language network in pre-literate children (mean age = 4.2 years). We tested how language abilities, brain activation, and connectivity predict children's reading abilities 1 year later (mean age = 5.2 years). At Time 1, children (n = 37) participated in a functional near infrared spectroscopy (fNIRS) experiment of speech processing (listening to words and pseudowords) and completed a standardized battery of language and cognitive assessments. At Time 2, children (n = 28)… [Direct]

Qahmash, Adel Ibrahim M (2018). The Potentials of Using Mobile Technology in Teaching Individuals with Learning Disabilities: A Review of Special Education Technology Literature. TechTrends: Linking Research and Practice to Improve Learning, v62 n6 p647-653 Nov. Within the literature, a respectful number of studies related to the use of assistive technologies for special education, resulting in an enormous agenda that encompasses various types of assistive technology applied across disabilities in different types of curricula. These disabilities include, but are not limited to: learning disabilities, mild, moderate and severe mental retardation, speech and communication disorders, hearing and speaking disabilities, and autism Hence, under the intertwined and overlapping umbrellas of assistive technologies and special education, mobile technology finds its promising, new spot on the surface of emerging assistive technologies in the field of special education. This paper addresses the potentials of using mobile technology in teaching individuals with developmental disorders based on current literature…. [Direct]

Ballesteros, Rachelle Lintao; Lontoc Macam, April; Salayo, Juland Dayo (2018). Solidarity and Disagreements: Social Dimensions in Cooperative Writing Group. Journal on English Language Teaching, v8 n1 p30-43 Jan-Mar. Using conversational analysis as a methodological framework, this paper aims to analyze the sequential pattern of the turns in cooperative writing group interactions which unfolds solidarity building and disagreement episodes. Recorded verbal and non-verbal interactions of a group, comprised of ten members, were carefully transcribed to closely examine overlapping, latching, cut-off and other pragmatic cues of the turn taking. Results show that solidarity building is displayed using collaborative construction turn strategy and laughter strategies. Disagreement as a preferred act is an effective speech strategy that does not only use in pursuit of knowledge, but could also establish group cohesiveness. Data also opens implications for English Language Teaching (ELT) specifically in promoting pragmatic competence among English as a Second Language (ESL) learners…. [PDF]

Abdulaziz Alshahrani (2023). Discourse Analysis of Male and Female Representatives of Selected Countries at the United Nations General Debates. AILA Review, v36 n2 p163-193. The aim of this paper was to evaluate gender differences in the language used in United Nations (UN) General Assembly debates by one male and one female representative each from India, China, the USA, and Indonesia. The critical discourse analysis (CDA) framework of van Dijk (2015) was used along with the 25 discursive devices in this framework. The data on frequencies of variables were analysed statistically. No significant differences were observed between positive comments about oneself, negative comments about others, length of speech (in words), and the various devices by the gender of the speaker at the 0.05 level of significance. However, gender differences in terms of higher levels for males than for females were observed for populism (t(6)= 2.354, p= 0.057), norm expression (t(6)= 2.171, p= 0.073), and positive comments about oneself (t(6)= 2.224, p= 0.068). The correlation coefficients were significant between genders for positive-self, norm expression, and national… [Direct]

Black, Alexis K.; Choi, Dawoon; Werker, Janet F. (2018). Cascading and Multisensory Influences on Speech Perception Development. Mind, Brain, and Education, v12 n4 p212-223 Dec. Over the first weeks and months following birth, infants' initial, broad-based perceptual sensitivities become honed to the characteristics of their native language. In this article, we review this process of emerging specialization within the context of a cascading "critical period" (CP) framework, in which periods of maximal openness to experience of different aspects of language occur at sequential, overlapping points in development. Importantly, as infants' experience of speech is not limited to auditory signals, but is informed by–for example–their experience of talking faces and their own oral motor movements, we review the trajectory of perceptual specialization in multisensory language processing. Throughout, we highlight the impact of increasing perceptual specialization on later language outcomes (e.g., word learning, foundations of syntax, literacy), and consider how the outcomes can be compromised if/when the timing of perceptual specialization has been… [Direct]

Anthony Joseph Rotolo (2022). Cancel Culture in Academia: Social Media Self-Presentation in the Context of Imagined Surveillance. ProQuest LLC, Ph.D. Dissertation, Grand Canyon University. The purpose of this qualitative descriptive study was to explore how academics in the United States described their social media self-presentations (SMSPs) in the context of imagined surveillance. Moral Reasoning Theory drove two RQs: (1) How do academics describe construction of SMSPs in the context of imagined surveillance? (2) How do academics describe the influence of imagined surveillance on their personal SMSPs? 106 academics from across the U.S. were recruited by convenience sampling from two scholarly associations. Data were collected from closed-/open-ended questionnaires (n = 102) and semi-structured interviews (n = 20). Data analysis applied a six-phased Reflexive Thematic Analysis procedure of inductive coding to generate five themes and 14 subthemes. Academics described SMSP construction as negotiating: (1) promises and perils of in/visibility, including (a) unspoken rules, (b) overlapping identities, (c) social support, and (d) personal opinion-sharing, which was… [Direct]

Gokgoz-Kurt, Burcu (2016). Attention Control and the Effects of Online Training in Improving Connected Speech Perception by Learners of English as a Second Language. Online Submission, Ph.D. Dissertation, University of South Carolina. One of the aspects of L2 English phonology which poses a challenge for L2 learners is learning how to decode the language, especially as spoken by native speakers. This difficulty may be due to the way the native speakers speak by 'draw[ing] [the sounds] together' (Clarey & Dixson, 1963), which results in realization of consonants and vowels differently than when uttered in isolation. This process is referred to as "connected speech" (e.g., pronouncing 'want to' as [characters omitted], and 'going to' as [characters omitted]). The challenge in teaching and learning these forms is that they lack perceptual saliency, requiring extra attentional resources for learners to be able to recognize these forms in spoken language. Therefore, a better understanding of the role of attention in learning these forms is needed. While some studies find a relationship between attention control as a cognitive ability and L2 phonological processing (Darcy, Mora & Daidone, 2014;… [PDF]

Delehanty, Abigail; Wetherby, Amy M. (2022). Coordinated Social Communication in Toddlers with and without Autism Spectrum Disorder during a Home Observation. Autism & Developmental Language Impairments, v7. Background & Aims: Social communication and language skills have been found to be important predictors of long-term outcomes in individuals with autism spectrum disorder (ASD). However, the development of coordinated social communication (i.e., gestures and sounds or words) remains relatively understudied in young children with ASD and developmental delays (DD). This study used a prospective, longitudinal design and granular observational coding to document the coordination of gestures, sounds, and words in a large, heterogeneous sample of toddlers identified with ASD, DD, or typical development (TD) during a naturalistic home observation. Specific aims were: (1) to compare rates per minute and proportions of coordinated child communicative acts across groups; (2) to examine concurrent relationships between coordinated communication and measures of social communication and autism symptoms; and (3) to examine prospective relationships between coordinated communication, receptive… [PDF] [Direct]

DeBarthe, Gina (2017). Impact of Alternative & Augmentative Communication on the Utterance Length of Children with Limited Oral Language. ProQuest LLC, Ph.D. Dissertation, University of Kansas. Children with limited oral language due to developmental and language delays have difficulty with communication in their everyday lives. Their trouble with speech and/or language impacts their ability to socialize with peers and learn in the school setting. Most of the research on alternative and augmentative communication systems and oral language has focused on the language development of children with less than 20 spoken words. The focus of this study is on the use of Alternative and Augmentative Communication Systems to increase oral language for children with limited oral language. Limited oral language is defined as being able to speak more than 20 words and an MLU of 2 or less. These alternative systems aid in expression and comprehension of language through visual and auditory means. Three boys age three to six were enrolled in the study lasting three months per child in an overlapping timeframe. Using a multiple baseline design during a shared book reading experience, the… [Direct]

Local, John (1980). Modelling Intonational Variability in Children. York Papers in Linguistics, n8 p61-96 Sep. The frequencies and co-occurrence distributions of some of the prosodic features in the speech of children are discussed. The emphasis is on the determination of systems and structure of non-segmental lectal variability in the children's speech without primary reference to function. The primary data consisted of selected episodes of connected speech from six Tyneside (England) children, three boys and three girls, aged 4.7 to 5.9 years. The episodes are all taken from tape-recordings in naturalistic settings in the children's homes. The system of analysis that was used treats prosodic features organized into independent, but interacting systems. The discussion of the research treats: (1) some of the similarities in the children's speech by examining details of the tone units which they realize; (2) some of the more important differences between the frequency distributions of nuclear tones in localized Tyneside and non-localized speech; and (3) overlapping representations of tonic… [PDF]

Bishop, Dorothy V. M.; Chow, Bonnie Wing-Yin; Ho, Connie Suk-Han; Waye, Mary M. Y.; Wong, Simpson W. L. (2014). Genetic and Environmental Overlap between Chinese and English Reading-Related Skills in Chinese Children. Developmental Psychology, v50 n11 p2539-2548 Nov. This twin study examined the relative contributions of genes and environment on 2nd language reading acquisition of Chinese-speaking children learning English. We examined whether specific skills-visual word recognition, receptive vocabulary, phonological awareness, phonological memory, and speech discrimination-in the 1st and 2nd languages have distinct or overlapping genetic and environmental origins. A sample of 279 Chinese twin pairs with a mean age of 6 years was tested. Univariate twin analyses were used to identify sources of individual variations in reading abilities and related cognitive-linguistic skills in Chinese and English, respectively. They were used to show both similar and distinctive patterns in these skills across Chinese and English. Bivariate Cholesky decomposition analyses indicated genetic overlaps between all parallel Chinese and English variables, as well as shared environmental overlaps in receptive vocabulary and phonological awareness.

Jones, Caroline; Meakins, Felicity; Muawiyath, Shujau (2012). Learning Vowel Categories from Maternal Speech in Gurindji Kriol. Language Learning, v62 n4 p1052-1078 Dec. Distributional learning is a proposal for how infants might learn early speech sound categories from acoustic input before they know many words. When categories in the input differ greatly in relative frequency and overlap in acoustic space, research in bilingual development suggests that this affects the course of development. In the present study we describe the nature and extent of vowel variation in nearly 900 vowel tokens in maternal speech in Gurindji Kriol, a mixed language of northern Australia, which, like bilingual input, has differences in the relative frequency of adjacent, overlapping vowel categories. In Analysis 1, we provide the first systematic account of vowel variation and phone frequency in maternal speech in Gurindji Kriol. In Analysis 2, cluster analysis was applied to the vowel formant and duration data, to see what categories might emerge from acoustic data alone. The results suggest that, were infants to base their initial vowel categories solely on the… [Direct]

Aichert, Ingrid; Staiger, Anja; Ziegler, Wolfram (2012). Apraxia of Speech: Concepts and Controversies. Journal of Speech, Language, and Hearing Research, v55 n5 pS1485-S1501 Oct. Purpose: This article was written as an editorial to a collection of original articles on apraxia of speech (AOS) in which some of the more recent advancements in the understanding of this syndrome are discussed. It covers controversial issues concerning the theoretical foundations of AOS. Our approach was motivated by a change of perspective on motor speech that has taken place in neurobiology, neurolinguistics, phonology, and phonetics during the past few decades. Method: The literature on AOS is reviewed from 3 different but overlapping perspectives–that is, a disconnection, a motor memory, and a fine motor skill perspective. Separate sections are devoted to the delimitations of AOS from oral facial apraxia, dysarthria, and phonological impairment. Conclusions: We conclude that many of the still unresolved conceptual issues about AOS arise from an underspecification of existing models of spoken language production. We suggest that phonological and motor impairments of sound… [Direct]

Frost, Stephen J.; Landi, Nicole; Mencl, W. Einar; Pugh, Kenneth R.; Sandak, Rebecca (2013). Neurobiological Bases of Reading Comprehension: Insights from Neuroimaging Studies of Word-Level and Text-Level Processing in Skilled and Impaired Readers. Reading & Writing Quarterly, v29 n2 p145-167. For accurate reading comprehension, readers must first learn to map letters to their corresponding speech sounds and meaning, and then they must string the meanings of many words together to form a representation of the text. Furthermore, readers must master the complexities involved in parsing the relevant syntactic and pragmatic information necessary for accurate interpretation. Failure in this process can occur at multiple levels, and cognitive neuroscience has been helpful in identifying the underlying causes of success and failure in reading single words and in reading comprehension. In general, neurobiological studies of skilled reading comprehension indicate a highly overlapping language circuit for single-word reading, reading comprehension, and listening comprehension, with largely quantitative differences in a number of reading- and language-related areas. This article reviews relevant research from studies that have used neuroimaging techniques to study reading with a… [Direct]

Hagoort, Peter; Menenti, Laura; Segaert, Katrien (2012). The Neuronal Infrastructure of Speaking. Brain and Language, v122 n2 p71-80 Aug. Models of speaking distinguish producing meaning, words and syntax as three different linguistic components of speaking. Nevertheless, little is known about the brain's integrated neuronal infrastructure for speech production. We investigated semantic, lexical and syntactic aspects of speaking using fMRI. In a picture description task, we manipulated repetition of sentence meaning, words, and syntax separately. By investigating brain areas showing response adaptation to repetition of each of these sentence properties, we disentangle the neuronal infrastructure for these processes. We demonstrate that semantic, lexical and syntactic processes are carried out in partly overlapping and partly distinct brain networks and show that the classic left-hemispheric dominance for language is present for syntax but not semantics.

Journal of Speech, Language, and Hearing Research, v55 n3 p879-891 Jun. Method: Complete psychometric functions for phoneme and word recognition scores at 8 signal-to-noise ratios from -15 dB to 20 dB were generated for the first 10, 20, and 25, as well as all 50, three-word presentations of the Tri-Word or Computer Assisted Speech Recognition Assessment (CASRA) Test (Gelfand, 1998) based on the results of 12 normal-hearing young adult participants from the original study. Results: The psychometric functions for both phoneme and word scores were very similar and essentially overlapping for all set sizes. Performance on the shortened tests accounted for 98.8% to 99.5% of the full (50-set) test variance with phoneme scoring, and 95.8% to 99.2% of the full test variance with word scoring. Shortening the tests accounted for little if any of the variance in the slopes of the functions. Conclusions: The psychometric functions for abbreviated versions of the Tri-Word speech recognition test using 10, 20, and 25 presentation sets were described and are… [Direct]

Saffran, Jenny R.; Sahni, Sarah D.; Seidenberg, Mark S. (2010). Connecting Cues: Overlapping Regularities Support Cue Discovery in Infancy. Child Development, v81 n3 p727-736 May-Jun. The present work examined the discovery of linguistic cues during a word segmentation task. Whereas previous studies have focused on sensitivity to individual cues, this study addresses how individual cues may be used to discover additional, correlated cues. Twenty-four 9-month-old infants were familiarized with a speech stream in which syllable-level transitional probabilities and an overlapping novel cue served as cues to word boundaries. Infants' behavior at test indicated that they were able to discover the novel cue. Additional experiments showed that infants did not have a preexisting preference for specific test items and that transitional probability information was necessary to acquire the novel cue. Results suggest one way learners can discover relevant linguistic structure amid the multiple overlapping properties of natural language…. [Direct]

Brown, Steven; Liotti, Mario; Takai, Osamu (2010). Representation of the Speech Effectors in the Human Motor Cortex: Somatotopy or Overlap?. Brain and Language, v113 n1 p39-44 Apr. Somatotopy within the orofacial region of the human motor cortex has been a central concept in interpreting the results of neuroimaging and transcranial magnetic stimulation studies of normal and disordered speech. Yet, somatotopy has been challenged by studies showing overlap among the effectors within the homunculus. In order to address this dichotomy, we performed four voxel-based meta-analyses of 54 functional neuroimaging studies of non-speech tasks involving respiration, lip movement, tongue movement, and swallowing, respectively. While the centers of mass of the clusters supported the classic homuncular view of the motor cortex, there was significant variability in the locations of the activation-coordinates among studies, resulting in an overlapping arrangement. This \somatotopy with overlap\ might reflect the intrinsic functional interconnectedness of the oral effectors for speech production. (Contains 2 tables and 1 figure.)… [Direct]

Kelsey F. Burren (2023). When Red Apples Are Green: Generalization by Picture Type. ProQuest LLC, Ph.D. Dissertation, Western New England University. Matching related stimuli is a foundational skill upon which a wide variety of critical repertoires are constructed. For learners with complex communication needs, including many children with autism, learned relations between pictorial stimuli and their referents are the basis for communication (Andzik et al., 2017; Crowe et al., 2021). Augmentative and alternative communication (AAC) tools enable such learners to engage in verbal behavior through the use of two-dimensional images, hereafter, pictures. These pictures are used to indicate real-world objects, persons, or activities to a communication partner. The form of these pictures varies widely; some pictures share many stimulus features with their real-world referents (e.g., photographs), whereas others share no discernable features (e.g., alphanumeric characters; McIlvane et al., 1993). Some children struggle to learn relations between pictures and their real-world referents, which can impede their access to such communication… [Direct]

Kogovsek, Damjana; Ozbic, Martina (2010). Vowel Formant Values in Hearing and Hearing-Impaired Children: A Discriminant Analysis. Deafness and Education International, v12 n2 p99-128 Jun. Hearing-impaired speakers show changes in vowel production and formant pitch and variability, as well as more cases of overlapping between vowels and more restricted formant space, than hearing speakers; consequently their speech is less intelligible. The purposes of this paper were to determine the differences in vowel formant values between 32 hearing speakers, 14 severely hearing-impaired speakers, and 25 profoundly hearing impaired speakers, and to investigate the influence of perceptual constraints on the contrastiveness of spoken vowels in speakers with hearing loss, as these underline the importance of good phonation, articulation, and resonance in speech production. Several differences in formant values were confirmed with Anova-Welch tests, except for the F1 of open /e/ and /a/, the most open and loud vowels in Slovene. In addition, discriminant analysis showed real differences in vowel production (97.1% classification success), thus making it possible to differentiate… [Direct]

Laganaro, Marina (2012). Patterns of Impairments in AOS and Mechanisms of Interaction between Phonological and Phonetic Encoding. Journal of Speech, Language, and Hearing Research, v55 n5 pS1535-S1543 Oct. Purpose: One reason why the diagnosis of apraxia of speech (AOS) and its underlying impairment are often debated may lie in the fact that most patients do not display pure patterns of AOS. Mixed patterns are clearly acknowledged at other levels of impairment (e.g., lexical-semantic and lexical-phonological), and they have contributed to debate about the degree of interaction between encoding levels; by contrast, mixed impairments and mechanisms of interaction are less acknowledged at the levels of phonological and phonetic processes. Here, the author aims at bringing together empirical evidence in favor of an interaction between phonological and phonetic encoding and of the predominance of mixed patterns of impairment over pure phonetic impairment. Method: The author reviews empirical results from acoustic and psycholinguistic studies, both with healthy speakers and speakers with brain damage, favoring independent phonological and phonetic encoding and separable impairments as well… [Direct]

Powell, Martine B.; Sanger, Dixie D.; Snow, Pamela C. (2012). Oral Language Competence, Young Speakers, and the Law. Language, Speech, and Hearing Services in Schools, v43 n4 p496-506 Oct. Purpose: This paper highlights the forensic implications of language impairment in 2 key (and overlapping) groups of young people: identified victims of maltreatment (abuse and/or neglect) and young offenders. Method: Two lines of research pertaining to oral language competence and young people's interface with the law are considered: 1 regarding investigative interviewing with children as victims or witnesses in the context of serious allegations of sexual abuse, and the other pertaining to adolescent offenders as suspects, witnesses, or victims. The linguistic demands that forensic interviewing places on these young people are also considered. Literature concerning the impact of early maltreatment on early language acquisition is briefly reviewed, as is the role of theory of mind in relation to the requirements of investigative interviewing of children and adolescents. Implications: High-risk young people (i.e., those who are subject to child protection orders because of suspected… [Direct]

Journal of Speech, Language, and Hearing Research, v53 n3 p609-619 Jun. Purpose: Behavioral genetic studies of speech fluency have focused on participants who present with clinical stuttering. Knowledge about genetic influences on the development and regulation of normal speech fluency is limited. The primary aims of this study were to identify the heritability of stuttering and high nonfluency and to assess the relative contribution of genetic and environmental factors to the correlation between these 2 fluency phenotypes. Method: Information on 6 specific speech fluency behaviors was obtained by maternal report for over 10,500 5-year-old Dutch twin pairs. Results: Genetic analyses revealed that both fluency phenotypes were moderately heritable, with heritability estimates of 42% and 45% for probable stuttering and high nonfluency, respectively. Shared environmental factors were also significant, explaining 44% of the individual differences in probable stuttering and 32% in nonfluency. For both phenotypes, the magnitude of the genetic and environmental… [Direct]

ProQuest LLC, Ph.D. Dissertation, University of Colorado at Boulder. This study is an exploration of alternative teacher professional development. While using symbolic interactionism for a research lens, it characterizes the discursive practices commonly found in formal, informal, and blended-space speech communities based on the talk within a leadership-development program comprised of five female, church-based small group leaders. The author designed, facilitated, and researched the discourse accounting for the formal professional development design and informal discursive practices which comprised this blended-space speech community. The author provides an overview of the leadership-development program design along with the sociolinguistic research methods. The analysis describes both above-the-sentence and turn-by-turn discursive practices for the group's talk. This includes above-the-sentence discursive practices of managing the conversational floor, enacting discursive power, offering representations of reality, and maintaining appropriate… [Direct]

Crutch, Sebastian J.; Rohrer, Jonathan D.; Warren, Jason D.; Warrington, Elizabeth K. (2010). Progranulin-Associated Primary Progressive Aphasia: A Distinct Phenotype?. Neuropsychologia, v48 n1 p288-297 Jan. The neuropsychological features of the primary progressive aphasia (PPA) syndromes continue to be defined. Here we describe a detailed neuropsychological case study of a patient with a mutation in the progranulin (\GRN\) gene who presented with progressive word-finding difficulty. Key neuropsychological features in this case included gravely impoverished propositional speech with anomia and prolonged word-finding pauses, impaired speech repetition most marked for sentences, and severely impaired verbal (with preserved spatial) short-term memory. There was a dissociated profile of performance on semantic processing tasks: visual semantic processing was intact, while within the verbal domain, verb comprehension was impaired and processing of nouns was intact on tasks requiring direct semantic processing but impaired on tasks requiring associative or inferential processing. Brain MRI showed asymmetric left cerebral atrophy particularly affecting the temporo-parietal junction,… [Direct]

Fernald, Anne; Hurtado, Nereyda; Marchman, Virginia A. (2008). Does Input Influence Uptake? Links between Maternal Talk, Processing Speed and Vocabulary Size in Spanish-Learning Children. Developmental Science, v11 n6 pF31-F39 Nov. It is well established that variation in caregivers' speech is associated with language outcomes, yet little is known about the learning principles that mediate these effects. This longitudinal study (n = 27) explores whether Spanish-learning children's early experiences with language predict efficiency in real-time comprehension and vocabulary learning. Measures of mothers' speech at 18 months were examined in relation to children's speech processing efficiency and reported vocabulary at 18 and 24 months. Children of mothers who provided more input at 18 months knew more words and were faster in word recognition at 24 months. Moreover, multiple regression analyses indicated that the influences of caregiver speech on speed of word recognition and vocabulary were largely overlapping. This study provides the first evidence that input shapes children's lexical processing efficiency and that vocabulary growth and increasing facility in spoken word comprehension work together to support… [Direct]
