African American Preschoolers' Performance on Norm-Referenced Language Assessments: Examining the Effect of Dialect Density and the Use of Scoring Modifications

PURPOSE

We investigated and compared the outcomes from two standardized, norm-referenced screening assessments of language (i.e., Clinical Evaluation of Language Fundamentals Preschool-Second Edition [CELFP-2], Diagnostic Evaluation of Language Variation-Screening Test [DELV-ST]) with African American preschoolers whose spoken dialect differed from that of General American English (GAE). We (a) described preschoolers' performance on the CELFP-2 Core Language Index (CLI) and its subtests with consideration of degree of dialect variation (DVAR) observed, (b) investigated how the application of dialect-sensitive scoring modifications to the expressive morphology and syntax Word Structure (WS) subtest affected CELFP-2 CLI scores, and (c) evaluated the screening classification agreement rates between the DELV-ST and the CELFP-2 CLI.

METHOD

African American preschoolers (N = 284) completed the CELFP-2 CLI subtests (i.e., Sentence Structure, WS, Expressive Vocabulary) and the DELV-ST. Density of spoken dialect use was estimated with the DELV-ST Part I Language Variation Status, and percentage of DVAR was calculated. The CELFP-2 WS subtest was scored with and without dialect-sensitive scoring modifications.

RESULTS

Planned comparisons of CELFP-2 CLI performance indicated statistically significant differences in performance based on DELV-ST-determined degree of language variation groupings. Scoring modifications applied to the WS subtest increased subtest scaled scores and CLI composite standard scores. However, preschoolers who demonstrated strong variation from GAE continued to demonstrate significantly lower performance than preschoolers who demonstrated little to no language variation. Affected-status agreement rates between assessments (modified and unmodified CELFP-2 CLI scores and DELV-ST Part II Diagnostic Risk Status) were extremely low.

CONCLUSIONS

The application of dialect-specific scoring modifications to standardized, norm-referenced assessments of language must be simultaneously viewed through the lenses of equity, practicality, and psychometry. The results of our multistage study reiterate the need for reliable methods of identifying risk for developmental language disorder within children who speak American English dialects other than GAE.

Consonant Cluster Productions in Preschool Children Who Speak African American English

PURPOSE

The aim of this study was to compare word-initial and word-final consonant cluster productions in young children who speak African American English (AAE) and compare their productions to what we know about cluster productions in children who speak Mainstream American English (MAE), in order to minimize misdiagnosis of speech sound disorders.

METHOD

Twenty-two children (ages 2;10-5;4 [years;months]) labeled pictures whose names contained at least one consonant cluster in word-initial and/or word-final position. Most two-element clusters of English were sampled, the majority in two or more words. The participants' responses were transcribed using a consensus transcription procedure. Each cluster attempt was analyzed for its similarity with MAE.

RESULTS

Percentage matching scores were significantly higher for word-initial than word-final clusters. Word-final clusters produced as singletons were significantly more common than word-final cluster substitutions. However, word-initial cluster substitutions were significantly more common than word-initial clusters produced as singletons. Word-initial cluster mismatches were consistent with markedness theory and the sonority sequencing principle (SSP). By contrast, word-final cluster mismatches were not consistent with the SSP, while the voicing generalization seen in adult speakers of AAE was evident.

CONCLUSION

Culturally and linguistically appropriate assessment of phonological development in children who speak AAE requires an understanding of the contrastive and noncontrastive features exemplified in their consonant cluster productions.

Children's English Consonant Acquisition in the United States: A Review

Purpose Speech-language pathologists' clinical decision making and consideration of eligibility for services rely on quality evidence, including information about consonant acquisition (developmental norms). The purpose of this review article is to describe the typical age and pattern of acquisition of English consonants by children in the United States. Method Data were identified from published journal articles and assessments reporting English consonant acquisition by typically developing children living in the United States. Sources were identified through searching 11 electronic databases, review articles, the Buros database, and contacting experts. Data describing studies, participants, methodology, and age of consonant acquisition were extracted. Results Fifteen studies (six articles and nine assessments) were included, reporting consonant acquisition of 18,907 children acquiring English in the United States. These cross-sectional studies primarily used single-word elicitation. Most consonants were acquired by 5;0 (years;months). The consonants /b, n, m, p, h, w, d/ were acquired by 2;0-2;11; /ɡ, k, f, t, ŋ, j/ were acquired by 3;0-3;11; /v, ʤ, s, ʧ, l, ʃ, z/ were acquired by 4;0-4;11; /ɹ, ð, ʒ/ were acquired by 5;0-5;11; and /θ/ was acquired by 6;0-6;11 (ordered by mean age of acquisition, 90% criterion). Variation was evident across studies resulting from different assessments, criteria, and cohorts of children. Conclusions These findings echo the cross-linguistic findings of McLeod and Crowe (2018) across 27 languages that children had acquired most consonants by 5;0. On average, all plosives, nasals, and glides were acquired by 3;11; all affricates were acquired by 4;11; all liquids were acquired by 5;11; and all fricatives were acquired by 6;11 (90% criterion). As speech-language pathologists apply this information to clinical decision making and eligibility decisions, synthesis of knowledge from multiple sources is recommended.

Nonword Repetition Across Two Dialects of English: Effects of Specific Language Impairment and Nonmainstream Form Density

Purpose Nonword repetition (NWR) has been proposed as a culturally and linguistically fair measure of children's language abilities that is useful for the identification of specific language impairment (SLI). However, Moyle, Heilmann, and Finneran (2014) suggested that the density of a child's nonmainstream forms also influences NWR in ways that could complicate its use. Using speakers of either African American English (AAE) or Southern White English (SWE), we asked if NWR performance differed in children with SLI and same dialect-speaking typically developing (TD) children and if nonmainstream form density impacted their scores. Method The participants were 106 kindergartners (AAE: SLI n = 35; TD n = 35; SWE: SLI n = 18; TD n = 18; groups matched for age and IQ) who performed the NWR task of Dollaghan and Campbell (1998) . Nonmainstream form density measures were gathered from listener judgments of conversational samples. Results NWR performance differed between those with and without SLI, but the difference was smaller in AAE than in SWE, especially at the longest syllable length. Nonmainstream form density was found to further explain NWR performance beyond the children's SLI status for AAE speakers; density and SLI status were confounded for the SWE speakers, making it harder to disentangle the effects of each in that dialect. Conclusions Results indicate the NWR may differ in diagnostic utility between speakers of different dialects. Results also support Moyle et al.'s (2014) finding that density affects NWR. Thus, NWR is more sensitive to dialectal differences than originally assumed.

Children's Consonant Acquisition in 27 Languages: A Cross-Linguistic Review

PURPOSE

The aim of this study was to provide a cross-linguistic review of acquisition of consonant phonemes to inform speech-language pathologists' expectations of children's developmental capacity by (a) identifying characteristics of studies of consonant acquisition, (b) describing general principles of consonant acquisition, and (c) providing case studies for English, Japanese, Korean, and Spanish.

METHOD

A cross-linguistic review was undertaken of 60 articles describing 64 studies of consonant acquisition by 26,007 children from 31 countries in 27 languages: Afrikaans, Arabic, Cantonese, Danish, Dutch, English, French, German, Greek, Haitian Creole, Hebrew, Hungarian, Icelandic, Italian, Jamaican Creole, Japanese, Korean, Malay, Maltese, Mandarin (Putonghua), Portuguese, Setswana (Tswana), Slovenian, Spanish, Swahili, Turkish, and Xhosa.

RESULTS

Most studies were cross-sectional and examined single word production. Combining data from 27 languages, most of the world's consonants were acquired by 5;0 years;months old. By 5;0, children produced at least 93% of consonants correctly. Plosives, nasals, and nonpulmonic consonants (e.g., clicks) were acquired earlier than trills, flaps, fricatives, and affricates. Most labial, pharyngeal, and posterior lingual consonants were acquired earlier than consonants with anterior tongue placement. However, there was an interaction between place and manner where plosives and nasals produced with anterior tongue placement were acquired earlier than anterior trills, fricatives, and affricates.

CONCLUSIONS

Children across the world acquire consonants at a young age. Five-year-old children have acquired most consonants within their ambient language; however, individual variability should be considered.

How African American English-Speaking First Graders Segment and Rhyme Words and Nonwords With Final Consonant Clusters

Purpose

This study explored how typically developing 1st grade African American English (AAE) speakers differ from mainstream American English (MAE) speakers in the completion of 2 common phonological awareness tasks (rhyming and phoneme segmentation) when the stimulus items were consonant–vowel–consonant–consonant (CVCC) words and nonwords.

Method

Forty-nine 1st graders met criteria for 2 dialect groups: AAE and MAE. Three conditions were tested in each rhyme and segmentation task: Real Words No Model, Real Words With a Model, and Nonwords With a Model.

Results

The AAE group had significantly more responses that rhymed CVCC words with consonant–vowel–consonant words and segmented CVCC words as consonant–vowel–consonant than the MAE group across all experimental conditions. In the rhyming task, the presence of a model in the real word condition elicited more reduced final cluster responses for both groups. In the segmentation task, the MAE group was at ceiling, so only the AAE group changed across the different stimulus presentations and reduced the final cluster less often when given a model.

Conclusion

Rhyming and phoneme segmentation performance can be influenced by a child's dialect when CVCC words are used.

Teachers' screening estimations of speech-language impairments in primary school children in Nepal

BACKGROUND

The prevalence of speech-language impairments in children have been estimated for several languages, primarily in developed countries. However, prevalence data is lacking for developing countries, such as Nepal.

AIMS

(1) To obtain teacher estimates of incidence and overall prevalence of speech-language impairments and its subtypes as a function of gender, age and grade level; and (2) to validate the screening instrument on Nepalese children.

METHODOLOGY

The adapted teachers' screening instrument, namely adapted Teachers' Speech and Language Referral Checklist (a-TSLRC), was administered in 2776 (690 and 2086) primary school children aged 5;00-11;11 years (mean = 8;11 years). The screening was conducted at four different points in time, i.e. Incidences I and II, and each incidence consisted of a testing and a retesting phase. Prior to this, teachers were trained in forum meetings, and an information sheet containing an overview of speech-language impairments, and guidelines/criteria for marking the occurrence of speech-language impairments in the TSLRC were disseminated.

OUTCOMES & RESULTS

Overall prevalence of speech-language impairments in children was estimated as 8.11%. Specifically, overall speech problems were estimated as 4.68%, and language problems as 8.0%. Additionally, the prevalence by subtypes of speech-language impairments as categorized in the TSLRC were reported to be 2.95% for an articulation/phonological problems, 2.09% for stuttering, 3.42% for a voice problems, 4.97% for a receptive language problems and 7.74% for an expressive language problems. The internal consistency among items was sufficient and a good intra-rater reliability was obtained.

CONCLUSIONS & IMPLICATIONS

The study indicates that the overall results of speech-language impairments in children via the adapted in-Nepalese criterion-referenced instrument are supported by international studies. In addition, justifiable reliability and validity was obtained. Therefore, based on these overall evidence, this instrument can be useful for the screening of speech-language impairments in primary school children in Nepal.

Content coverage of single-word tests used to assess common phonological error patterns

PURPOSE

This review evaluated whether 9 single-word tests of phonological error patterns provide adequate content coverage to accurately identify error patterns that are active in a child's speech.

METHOD

Tests in the current study were considered to display sufficient opportunities to assess common phonological error patterns if they provided at least 4 opportunities for each of 11 error patterns. The target phonemes for these error patterns had to occur as singletons (except for final consonant deletion and cluster reduction) and in stressed syllables (except for weak syllable deletion). Error patterns for which positional asymmetries have been documented (velar fronting, stopping of fricatives and affricates, and cluster reduction) required 4 opportunities in both word-initial and word-final position to meet the study's criterion.

RESULTS

None of the tests provided 4 opportunities for every error pattern, the criterion level used in this study. Error patterns that tended to be underrepresented across tests included weak syllable deletion, reduction of word-final clusters, fronting of velars, gliding of liquids, and deaffrication.

CONCLUSION

This review will allow clinicians to gain a deeper understanding of the methods used to assess phonological error patterns in single-word tests.

Psychometric Characteristics of Single-Word Tests of Children's Speech Sound Production

Purpose

Our understanding of test construction has improved since the now-classic review by McCauley and Swisher (1984). The current review article examines the psychometric characteristics of current single-word tests of speech sound production in an attempt to determine whether our tests have improved since then. It also provides a resource that clinicians may use to help them make test selection decisions for their particular client populations.

Method

Ten tests published since 1990 were reviewed to determine whether they met the 10 criteria set out by McCauley and Swisher (1984), as well as 7 additional criteria.

Results

All of the tests reviewed met at least 3 of McCauley and Swisher's (1984) original criteria, and 9 of 10 tests met at least 5 of them. Most of the tests met some of the additional criteria as well.

Conclusions

The state of the art for single-word tests of speech sound production in children appears to have improved in the last 30 years. There remains, however, room for improvement.

Zero Marking of Past Tense in Child African American English

Zero marking of the simple past is often listed as a common feature of child African American English (AAE). In the current paper, we review the literature and present new data to help clinicians better understand zero marking of the simple past in child AAE. Specifically, we provide information to support the following statements: (a) By six years of age, the simple past is infrequently zero marked by typically developing AAE-speaking children; (b) There are important differences between the simple past and participle morphemes that affect AAE-speaking children's marking options; and (c) In addition to a verb's grammatical function, its phonetic properties help determine whether an AAE-speaking child will produce a zero marked form.

The role of dialect density in nonword repetition performance: an examination with at-risk African American preschool children

The Nonword Repetition Task (NRT) is considered to be a less-biased language measure for children from cultural minority groups. In the current study, we examined NRT performance of 50 at-risk, preschool-age children who spoke African American English (AAE). In addition to the NRT, measures included AAE dialect density and several standardised language tests. The primary aim was to determine significant contributors to NRT performance. We hypothesised that the language measures would significantly contribute to NRT performance while dialect density would be an insignificant contributor. Contrary to our predictions, dialect density was a unique and significant predictor of NRT performance (in addition to phonological awareness), while the language measures were not significant predictors. The current findings cast doubt on categorising the NRT as a less-biased language assessment for AAE-speaking preschoolers; however, the NRT may have potential as a screener for identifying preschoolers at risk for delays in literacy acquisition.

Examining the use of spoken dialect indices with African American children in the southern United States

PURPOSE

To examine the utility of different dialect indices that have been used to characterize the Non-Mainstream American English (NMAE) dialect of African American children. The relationships among 4 popular dialect indices were examined and compared with the results of a standardized tool used to classify the language variation of child speakers at 3 different grade levels.

METHOD

The authors used listener judgment ratings, 2 dialect density measures obtained from a narrative sample, a standardized tool (Part 1 of the Diagnostic Evaluation of Language Variation-Screener Test [DELV-ST; Seymour, Roper, & deVilliers, 2003]), and dialect variation scores (DVAR) obtained from the DELV-ST to characterize 113 African American children's spoken production of NMAE.

RESULTS

Grade-level effects on NMAE varied depending on the index used to measure dialect production. All of the dialect indices under investigation were related to one another. DELV-ST classification group effects were present on all but 1 of the indices used to capture NMAE.

CONCLUSIONS

Newer measures of NMAE, such as the DELV-ST and DVAR scores, are comparable to older measures such as dialect density measures and listener judgment ratings. Like listener judgment ratings, the DELV-ST and DVAR scores offer clinicians and researchers alike a quicker alternative to dialect density measures for confirming and quantifying the spoken production of NMAE dialect. The present findings confirm that, depending on the type of data collected and questions posed, researchers and clinicians alike are able to choose from multiple, valid, and reliable measures of non-mainstream dialect use.

Cross-linguistic comparison of speech errors produced by English- and French-speaking preschool-age children with developmental phonological disorders

Twenty-four French-speaking children with developmental phonological disorders (DPD) were matched on percentage of consonants correct (PCC)-conversation, age, and receptive vocabulary measures to English-speaking children with DPD in order to describe how speech errors are manifested differently in these two languages. The participants' productions of consonants on a single-word test of articulation were compared in terms of feature-match ratios for the production of target consonants, and type of errors produced. Results revealed that the French-speaking children had significantly lower match ratios for the major sound class features [+ consonantal] and [+ sonorant]. The French-speaking children also obtained significantly lower match ratios for [+ voice]. The most frequent type of errors produced by the French-speaking children was syllable structure errors, followed by segment errors, and a few distortion errors. On the other hand, the English-speaking children made more segment than syllable structure and distortion errors. The results of the study highlight the need to use test instruments with French-speaking children that reflect the phonological characteristics of French at multiple levels of the phonological hierarchy.

Seeking a valid gold standard for an innovative, dialect-neutral language test

PURPOSE In this study, the authors explored alternative gold standards to validate an innovative, dialect-neutral language assessment. METHOD Participants were 78 African American children, ages 5;0 (years;months) to 6;11. Twenty participants had previously been identified as having language impairment. The Diagnostic Evaluation of Language Variation-Norm Referenced (DELV-NR; Seymour, Roeper, & J. de Villiers, 2005) was administered, and concurrent language samples (LSs) were collected. Using LS profiles as the gold standard, sensitivity, specificity, and other measures of diagnostic accuracy were compared for diagnoses made from the DELV-NR and participants' clinical status prior to recruitment. In a second analysis, the authors used results from the first analysis to make evidence-based adjustments in the estimates of DELV-NR diagnostic accuracy. RESULTS Accuracy of the DELV-NR relative to LS profiles was greater than that of prior diagnoses, indicating that the DELV-NR was an improvement over preexisting diagnoses for this group. Specificity met conventional standards, but sensitivity was somewhat low. Reanalysis using the positive and negative predictive power of the preexisting diagnosis in a discrepant-resolution procedure revealed that estimates for sensitivity and specificity for the DELV-NR were .85 and .93, respectively. CONCLUSION The authors found that, even after making allowances for the imperfection of available gold standards, clinical decisions made with the DELV-NR achieved high values on conventional measures of diagnostic accuracy.

Measuring speech sound development: an item response model approach

RESEARCH AIM

The primary aim of our study is to investigate if there is an ordering in the speech sound development of children aged 3-6, similar to the ordering in general language development.

METHOD

The speech sound development of 1035 children was tested with a revised version of Logo-Articulation Assessment. The data were analyzed with the Mokken Scale Program (MSP) in order to construct scales with satisfactory scalability (H-coefficient) and sufficient reliability (rho).

RESULTS

The majority of children over 4.3 years of age turned out to have mastered most speech sounds. An ordering was only found in the youngest age group (3.8-4.3 years of age), for the sounds of /r/ in initial and final position and /s/ in initial position. This resulted in a set of scales. The scales developed for /r/ (in initial and final position) and /s/ were moderately scalable (H>0.43) and reliable (rho>0.83), and independent of gender. Moreover, we found variation in the judgment of speech sound development, which may perhaps have been due to where exactly the examiner was positioned during the assessment procedure: in front of the child, or sitting beside the child.

CONCLUSIONS

We could not detect an ordering for all speech sounds. We only found an ordering for /r/ in initial and final position and /s/ in initial position. In the Mokken analysis we conducted, these scales turned out to be moderately strong and reliable. Our research also underlines that speech sound development is judged not only in an auditory sense, but judgment also depends on the visual interpretation of the listener.

Toward validation of a minimal competence core of morphosyntax for African American children

PURPOSE

The authors set out to determine (a) whether African American children's spontaneous spoken language met use criteria for a revised minimal competence core with original and added morphosyntactic patterns at different geographical locations, and (b) whether pass/fail status on this core was differentiated on other criterion measures of language maturity.

METHOD

The authors used a common set of activities and stimuli to elicit spontaneous speech samples from Head Start students, age 3;0 (years; months). The 119 participants were distributed at a northern (Lansing, MI) and a southern (Baton Rouge, LA) location.

RESULTS

More than 80% of the children at each location met criteria for 10 core competencies. They included sentence length, type, complexity, and morphosyntactic elaborations of sentences at the lexical, phrasal, and clausal levels. The 2 most significant predictors of pass/fail outcomes in a regression analysis were (a) clinical referral status and (b) the number of different words (NDW(100)) spoken in a speech sample.

CONCLUSION

A minimal competence core analyses of spontaneous oral language samples may help to identify delayed spoken grammars in African American children.

Dialect-Neutral Indices of Narrative Cohesion and Evaluation

Purpose

This study compared the development of essential elements of narrative skill in children from African American English (AAE)- and general American English (GAE)-speaking communities using an innovative elicitation and evaluation protocol consisting of four key indices of narrative language: (a) reference contrasting, (b) temporal expressions, (c) mental state descriptions, and (d) understanding of behavior based on false belief.

Method

Participants were 291 AAE speakers and 238 GAE speakers, 4 to 9 years of age. Approximately one-third of both dialect groups were identified as having language impairments. Children generated 2 stories based on short picture sequences. Their stories were coded for the 4 key indices of narrative language. Analyses of variance were performed with subsets of the measures and a composite index with all measures combined as outcomes; and with age, dialect group, and clinical status as predictors.

Results

Age and clinical status had statistically significant effects on the subset measures and the composite score. Variation between AAE and GAE dialect was not a significant factor.

Conclusion

By focusing on dialect-neutral elements of narratives—creating links across sentences and providing mental state interpretations—this study adds to our knowledge of development and impairment in narrative production among both AAE- and GAE-background children.

Changing nonmainstream American English use and early reading achievement from kindergarten to first grade

PURPOSE

This study had 2 principal aims: (a) to examine whether children who spoke Nonmainstream American English (NMAE) frequently in school at the end of kindergarten increased their production of Mainstream American English (MAE) forms by the end of first grade, and (b) to examine concurrent and predictive relations between children's NMAE use and reading skills.

METHOD

A longitudinal design was implemented with 49 children who varied in their spoken NMAE production in kindergarten. Word reading, phonological awareness, and receptive vocabulary skills were measured at both time points.

RESULTS

Analyses indicated that most children significantly increased their production of MAE forms between the 2 time points; however, this change was not associated with change in letter-word reading and phonological awareness skills. Regression analyses showed that NMAE use in kindergarten contributed significantly and independently to the variance in word reading in first grade, even after accounting for phonological awareness (although word reading in kindergarten was the best predictor of word reading in first grade).

CONCLUSIONS

The findings extend previous reports of a significant relation between NMAE use and reading among young children. Theoretical, research, and educational implications of the findings are discussed.

Effect of dialect on identification and severity of speech impairment in Indigenous Australian children

This study investigated the effect of dialectal difference on identification and rating of severity of speech impairment in children from Indigenous Australian backgrounds. The speech of 15 Indigenous Australian children identified by their parents/caregivers and teachers as having 'difficulty talking and making speech sounds' was assessed using the Diagnostic Evaluation of Articulation and Phonology. Fourteen children were identified with speech impairment on the Diagnostic Evaluation of Articulation and Phonology using Standard Australian English (AusE) as the target pronunciation; whereas 13 were identified using Australian Aboriginal English (AAE) as the target. There was a statistically significant decrease in seven children's severity classification and a statistically significant increase in all children's percentage of consonants, vowels and phonemes correct when comparing AAE with AusE. Features of AAE used by the children included /h/ insertion and deletion, primary stress on the first syllable and diphthongs alternating with short clear vowels. It is important that speech-language pathologists consider children's dialect as one component of culturally and linguistically appropriate services.

Examining relationships among dialect variation, literacy skills, and school context in first grade

PURPOSE

This study examined relationships between the use of nonmainstream American English dialects, literacy skills, and school environment among typically developing first graders (n = 617), of whom 48% were African American and 52% were White, in order to describe and better understand the difficulties many children from linguistically diverse backgrounds experience while learning to read.

METHOD

Using hierarchical linear modeling, the authors examined the linear and quadratic relationships between students' dialect variation (DVAR) and their vocabulary, phonological awareness, and word reading skills, taking into account school environment, specifically schoolwide socioeconomic status (SES).

RESULTS

The relationships between DVAR and literacy outcomes depended on the outcome of interest and school SES. However, children's race did not generally affect the trajectory or strength of the relationships between outcomes and dialect variation. For vocabulary and word reading, the association was nonlinear, that is, U-shaped, but this depended on school SES. For phonological awareness, a negative linear relationship was observed that did not depend on school SES.

CONCLUSIONS

The results inform theories on the relationship between DVAR and literacy achievement and suggest a more complex explanation of how nonmainstream American English dialect use might influence how young children learn to read.
