Variable use of African American English across two language sampling context

An exploratory study on dialect density estimation for children and adult's African American Englisha)

This paper evaluates an innovative framework for spoken dialect density prediction on children's and adults' African American English. A speaker's dialect density is defined as the frequency with which dialect-specific language characteristics occur in their speech. Rather than treating the presence or absence of a target dialect in a user's speech as a binary decision, instead, a classifier is trained to predict the level of dialect density to provide a higher degree of specificity in downstream tasks. For this, self-supervised learning representations from HuBERT, handcrafted grammar-based features extracted from ASR transcripts, prosodic features, and other feature sets are experimented with as the input to an XGBoost classifier. Then, the classifier is trained to assign dialect density labels to short recorded utterances. High dialect density level classification accuracy is achieved for child and adult speech and demonstrated robust performance across age and regional varieties of dialect. Additionally, this work is used as a basis for analyzing which acoustic and grammatical cues affect machine perception of dialect.

An examination of 3rd and 5th grade students' use of dialect specific forms during a written editing task

PURPOSE

The goal of the current study was to examine the role of variety and frequency of dialectal features in relation to General American English (GAE) editing ability. This study focused on speakers of dialect-specific forms and their ability to edit to GAE. To gain insight into this relation, the following research questions were posed: (1). How do third and fifth-grade students differ in the variety of features of dialect-specific forms they use, the frequency of their use, and their editing ability to GAE? (2). Is there a significant relation between dialect use and editing ability?

METHODS

Participants included 68 third and fifth-grade students who produced at least one dialect-specific form. We measured students' ability to edit to GAE during a written editing task. Frequency and variety of dialect use were based on an oral language sample where students were asked to share their favorite game or sport.

RESULTS

Fifth-grade students are significantly better at editing written dialect specific forms to reflect GAE writing conventions as compared to third-grade students. However, there was not a significant difference in the dialect specific form usage between the two grades. Finally, there was not a significant relation between dialect specific form use and editing ability.

CONCLUSIONS

These results offer relevant clinical and educational implications for increasing cultural responsivity and promote the use of multiple measures across modalities to gain relevant information when assessing students who use dialect specific forms. Further, the results from this study provide further insights into how written editing ability exhibited through the awareness of GAE conventions improves with age despite the influence of dialect specific forms.

Using Animated Action Scenes to Remotely Assess Sentence Diversity in Toddlers

Although language samples are child-friendly and well-suited for obtaining global measures of language production, structured protocols have the potential to elicit many different exemplars of language structures in a shorter amount of time. We created a structured elicitation protocol, the Sentence Diversity Priming Task (SDPT), to efficiently assess sentence diversity in toddlers via video chat platforms. Sentence diversity is operationalized as the number of different subject–verb combinations in active declarative sentences. The task is presented as an animated picture book, with parents serving as the child's primary partner during administration. In this article, we provide the rationale for assessing sentence diversity, describe the task, and present preliminary analyses of compliance and developmental associations for 32 typically developing toddlers, 30–35 months old, with average language abilities. The preliminary findings suggest that the SDPT is an engaging task that holds toddlers' attention, reveals robust individual differences in their ability to produce sentences, is positively correlated with parent-reported language measures, and has the potential for assessing children's language growth over time. Finally, recommendations and tips for developing and remotely administering the protocol are provided, with an emphasis on encouraging parent involvement and increasing toddler compliance.

Production of Morphosyntax Within and Across Different Dialects of American English

Purpose This study examined the production of morphosyntactic markers by school-age children with and without developmental language disorder. Comparisons were made between students who speak mainstream American English (MAE) dialects and nonmainstream American English (NMAE) dialects. Method First- and second-grade students (N = 82) completed assessments of dialect use and language ability, which are designed for students who speak NMAE dialects. Students also completed an experimental production task targeting three morphosyntactic features: past tense -ed marking, third-person singular -s marking, and plural -s marking. Past tense marking and third-person singular are produced differently across MAE and NMAE dialects, whereas plural marking is produced more similarly across dialects. Results When comparing across dialects, children with typical language skills who spoke NMAE dialects overtly marked past tense and third-person singular less often compared to MAE peers. However, when comparing to same-dialect peers with language disorders, children with typical language skills who spoke NMAE dialects overtly marked these morphosyntactic markers more often than peers with developmental language disorder. Conclusion The results underscore the importance of considering a child's dialect use when assessing language ability, in particular with measures that include features that are variable in NMAE dialects. At the same time, within-dialect comparisons suggest that a broader set of morphosyntactic features may provide useful information for evaluations of language ability. Future research should investigate the source of these differences, including the extent to which students with language disorders have acquired the social and linguistic factors that condition the use of variable features.

Language and Literacy Predictors of Dialect Density Among School-Age African American Children From Two Geographic Regions

Purpose The purpose of this study was to investigate the relationship between oral language, literacy skills, age, and dialect density (DD) of African American children residing in two different geographical regions of the United States (East Coast and Midwest). Method Data were obtained from 64 African American school-age children between the ages of 7 and 12 years from two geographic regions. Children were assessed using a combination of standardized tests and narrative samples elicited from wordless picture books. Bivariate correlation and multiple regression analyses were used to determine relationships to and relative contributions of oral language, literacy, age, and geographic region to DD. Results Results of correlation analyses demonstrated a negative relationship between DD measures and children's literacy skills. Age-related findings between geographic regions indicated that the younger sample from the Midwest outscored the East Coast sample in reading comprehension and sentence complexity. Multiple regression analyses identified five variables (i.e., geographic region, age, mean length of utterance in morphemes, reading fluency, and phonological awareness) that accounted for 31% of the variance of children's DD-with geographic region emerging as the strongest predictor. Conclusions As in previous studies, the current study found an inverse relationship between DD and several literacy measures. Importantly, geographic region emerged as a strong predictor of DD. This finding highlights the need for a further study that goes beyond the mere description of relationships to comparing geographic regions and specifically focusing on racial composition, poverty, and school success measures through direct data collection.

Effects of Specific Language Impairment on a Contrastive Dialect Structure: The Case of Infinitival TO Across Various Nonmainstream Dialects of English

Purpose

Using data from children who spoke various nonmainstream dialects of English and who were classified as either children with specific language impairment (SLI) or typically developing (TD) children, we examined children's marking of infinitival TO by their dialect and clinical status.

Method

The data came from 180 kindergartners (91 speakers of African American English, 60 speakers of Southern White English, 29 speakers of +Cajun); 53 were children with SLI, and 127 were TD children. Data included 4,537 infinitival TO contexts extracted from language samples; each was coded as zero or overtly marked and by preceding verb context (i.e., verbs of motion vs. other).

Results

Across dialects, overall rates of zero marking differed by the children's clinical status (SLI > TD), and other verb contexts accounted for this result. Across the TD and SLI groups, dialect variation was evident for verbs of motion contexts, and the effect was stronger for the TD than for the SLI groups, particularly if the TD children's dialects were classified as +Cajun.

Conclusion

Children's marking of infinitival TO can be affected by both their dialect and clinical status. Results support language assessments that include context-specific rate-based measures of infinitival TO and other contrastive structures when they prove useful for understanding the linguistic profile of SLI within a dialect.

The Impact of Dialect Density on the Growth of Language and Reading in African American Children

Purpose

The goal of the current study was to examine the impact of dialect density on the growth of oral language and reading skills in a sample of African American English (AAE)-speaking children reared in urban communities.

Method

Eight hundred thirty-five African American children in first through fifth grades participated. Using an accelerated cohort design, univariate and bivariate growth models were employed to examine dialect density, oral language and reading, and the relationships between these variables.

Results

For the univariate models, results indicated that (a) dialect density decreased over time by approximately 5% per year beyond first grade, (b) language skills improved approximately 0.5 SD per year, and (c) reading comprehension increased significantly from first to second grade and slowed 23% per year in second through fifth grades. Results from the bivariate models revealed that (a) dialect density and language ability are negatively associated, although dialect density did not affect change in language over time, and (b) higher dialect density is related to slower growth in reading.

Conclusions

Findings from this investigation provide converging evidence for accounts in the extant literature particularly supporting a negative relationship between dialect density and oral language and between dialect density and reading while also contributing novel longitudinal evidence that suggests that changes in dialect use over time may be driven by oral language skills and that reading and dialect have a reciprocal relationship.

Percent Grammatical Responses as a General Outcome Measure: Initial Validity

Purpose

This report investigated the validity of using percent grammatical responses (PGR) as a measure for assessing grammaticality. To establish construct validity, we computed the correlation of PGR with another measure of grammar skills and with an unrelated skill area. To establish concurrent validity for PGR, we computed the correlation of PGR with a previously validated measure of grammaticality, percent grammatical utterances (PGU), and examined the extent to which PGR and PGU agreed upon pass/fail decisions for children.

Method

Participants included 79 3-year-olds from mostly middle socioeconomic status homes. Language samples were elicited by asking children to describe 15 pictures in response to 4 questions per picture. To calculate PGU, children's responses to all 4 questions were segmented into communication units, and each communication unit was evaluated for grammatical errors. To calculate PGR, the entire response to just the first question was evaluated for grammatical errors.

Results

PGR scores significantly correlated with a standardized test of grammar (r = .70), but not with a measure of vocabulary (i.e., type-token ratio; r = .11). In addition, PGR scores were significantly correlated with PGU scores (r = .88). Agreement between PGR and PGU was 92% for pass decisions and 94% for fail decisions.

Conclusions

The current study establishes the construct validity of PGR as a measure of grammar and supports the use of PGR as a measure to assess grammaticality.

Elementary Students' Use of Dialect and Reading Achievement: Examining Students with Disabilities

Nonmainstream American English, or dialect, among children may have important implications for reading research and practice. However, much of the research involving relations between dialect and literacy has analyzed dialect use in only one context and has omitted students with speech, language, and learning disabilities. Consequently, we examined dialect use in an oral narrative and two writing samples in relation to concurrent and longitudinal reading outcomes in a diverse sample of students, including those with diagnosed disabilities. Overall, most students used features of dialect in oral and written language. Dialect use was significantly and negatively predictive of reading outcomes the same year and 2 years later. Moderator analyses indicated a similar relationship between dialect use and reading for students with speech, language, and learning disabilities, suggesting that students with these disabilities who also use dialect may be at increased risk for reading difficulties. Implications for practice and future research are provided.

Dialect Variation of Copula and Auxiliary Verb BE: African American English-Speaking Children With and Without Gullah/Geechee Heritage

PURPOSE

We compared copula and auxiliary verb BE use by African American English-speaking children with and without a creole heritage, using Gullah/Geechee as the creole criterion, to determine if differences exist, the nature of the differences, and the impact of the differences on interpretations of ability.

METHOD

Data came from 38 children, aged 5 to 6 years (19 with Gullah/Geechee and 19 without Gullah/Geechee heritage). All were developing language typically, with groups matched on gender, maternal education, and, when possible, test scores. The children's productions of BE were elicited using a screener, probes, and language samples.

RESULTS

Although many similarities were documented, the 2 groups' BE systems differed in 3 ways: use of unique forms (i.e., də), unique use of shared forms (i.e., BEEN), and rates of use of shared forms (e.g., am, is, was/were, was for were). Although most noticeable in the language samples, differences surfaced across tasks and showed the potential to affect interpretations of ability.

CONCLUSIONS

Dialect variation that is tied to children's creole heritage exists, involves 3 types of variation, and potentially affects interpretations of ability. Effects of a heritage language and different types of variation should be considered in research and clinical endeavors with African American English-speaking children.

Language Assessment With Children Who Speak Nonmainstream Dialects: Examining the Effects of Scoring Modifications in Norm-Referenced Assessment

Purpose

We compared outcomes from 2 measures of language ability in children who displayed a range of dialect variation: 1 using features that do not contrast between mainstream American English (MAE) and nonmainstream dialects (NMAE), and 1 using contrastive features. We investigated how modified scoring procedures affected the diagnostic accuracy of the measure with contrastive features.

Method

Second-grade students (N = 299; 167 White, 106 African American, 26 other) completed measures of language variation and ability (the Diagnostic Evaluation of Language Variation-Screening Test and the Clinical Evaluation of Language Fundamentals-Fourth Edition [CELF-4]). The CELF-4 was scored with and without the recommended scoring modifications for children who spoke African American English.

Results

Partial correlations controlling for socioeconomic status revealed small to moderate correlations between measures of language ability and the use of NMAE features. Modified scoring yielded higher scores for children who spoke African American English and a reduced association between the use of NMAE features and CELF-4 scores. Modified scoring also affected the diagnostic accuracy of the CELF-4, resulting in a lower positive likelihood ratio and a higher negative likelihood ratio.

Conclusions

The decision to apply scoring modifications affects both the false positive and false negative rates. Implications for language assessment for children who speak NMAE dialects are discussed, including the need for further investigation.

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.

BE, DO, and modal auxiliaries of 3-year-old African American English speakers

PURPOSE

This study examined African American English-speaking children's use of BE, DO, and modal auxiliaries.

METHOD

The data were based on language samples obtained from 48 three-year-olds. Analyses examined rates of marking by auxiliary type, auxiliary surface form, succeeding element, and syntactic construction and by a number of child variables.

RESULTS

The children produced 3 different types of marking (mainstream overt, nonmainstream overt, zero) for auxiliaries, and the distribution of these markings varied by auxiliary type. The children's nonmainstream dialect densities were related to their marking of BE and DO but not modals. Marking of BE was influenced by its surface form and the succeeding verbal element, and marking of BE and DO was influenced by syntactic construction.

CONCLUSIONS

Results extend previous studies by showing dialect-specific effects for children's use of auxiliaries and by showing these effects to vary by auxiliary type and children's nonmainstream dialect densities. Some aspects of the children's auxiliary systems (i.e., pattern of marking across auxiliaries and effects of syntactic construction) were also consistent with what has been documented for children who speak other dialects of English. These findings show dialect-specific and dialect-universal aspects of African American English to be present early in children's acquisition of auxiliaries.

Children's marking of verbal -s by nonmainstream English dialect and clinical status

PURPOSE

Children's marking of verbal -s was examined by their dialect (African American English [AAE] vs. Southern White English [SWE]) and clinical status (specific language impairment [SLI] vs. typically developing [TD]) and as a function of 4 linguistic variables (verb regularity, negation, expression of a habitual activity, and expression of historical present tense).

METHOD

The data were language samples from 57 six-year-olds who varied by their dialect and clinical status (AAE: SLI = 14, TD = 12; SWE: SLI = 12, TD = 19).

RESULTS

The AAE groups produced lower rates of marking than did the SWE groups, and the SWE SLI group produced lower rates of marking than did the SWE TD group. Although low numbers of verb contexts made it difficult to evaluate the linguistic variables, there was evidence of their influence, especially for verb regularity and negation. The direction and magnitude of the effects were often (but not always) consistent with what has been described in the adult dialect literature.

CONCLUSION

Verbal -s can be used to help distinguish children with and without SLI in SWE but not in AAE. Clinicians can apply these findings to other varieties of AAE and SWE and other dialects by considering rates of marking and the effects of linguistic variables on marking.

Students' Production of Narrative and AAE Features During an Emergent Literacy Task

Purpose

This study examined child production of narrative features and of African American English (AAE) during a wordless storybook oral narrative task.

Method

Participants were 30 AAE-speaking African American kindergarten and 1st grade students from low- and mid-socioeconomic status homes. Story grammar (SG), story literary technique (SLT), and AAE features were examined.

Results

Young AAE-speaking students used a variety of SG narrative features to develop the plot in their oral stories. Students also used multiple SLT elaborative features, though some techniques were used more frequently than others. The total SLT score positively predicted the total SG score, and the individual SLTs of adverbs or adjectives, references to the main theme, and character interactions were positively correlated with the total SG score. AAE-feature production rates did not predict the total SG score. However, several individual AAE features served specific narrative functions, with the preterite had, zero past tense, zero preposition, fitna/sposeta/bouta, and double marking features often being used to relay complicating actions within the narratives.

Conclusion

Young children used both AAE and elaborative features in their narratives. Particular AAE features facilitated plot development, and the use of more elaborative features positively predicted higher narrative development scores.

Differentiating children with and without language impairment based on grammaticality

PURPOSE

This study compared the diagnostic accuracy of a general grammaticality measure (i.e., percentage grammatical utterance; PGU) to 2 less comprehensive measures of grammaticality--a measure that excluded utterances without a subject and/or main verb (i.e., percentage sentence point; PSP) and a measure that looked only at verb tense errors (i.e., percentage verb tense usage; PVT)--in differentiating children with and without language impairment.

METHOD

Two groups of 3-year-olds, 17 with language impairment and 17 with typical language, participated in a picture description task. PGU, PSP, and PVT were computed. Receiver operating characteristic curve analyses were conducted to determine the best cutoff value for each measure.

RESULTS

All 3 measures demonstrated a sensitivity of 100%. PGU showed a specificity of 88%, and both PSP and PVT showed a specificity of 82%. In addition, PGU showed a larger positive likelihood ratio than the other 2 measures.

CONCLUSION

PGU, PSP, and PVT were all sensitive to language impairment. However, PGU was less likely than PSP and PVT to misclassify children with typical language. The resultant diagnostic accuracy makes PGU an appropriate measure to use to screen for language impairment.

Metalinguistics, stress accuracy, and word reading: does dialect matter?

PURPOSE

The authors examined the influence of demographic variables on nonmainstream American English (NMAE) use; the differences between NMAE speakers and mainstream American English (MAE) speakers on measures of metalinguistics, single-word reading, and a new measure of morphophonology; and the differences between the 2 groups in the relationships among the measures.

METHOD

Participants were typically developing 3rd graders from Memphis, TN, including 21 MAE and 21 NMAE speakers. Children received a battery of tests measuring phonological and morphological awareness (PA and MA), morphophonology (i.e., accurately produced lexical stress in derived words), decoding, and word identification (WID).

RESULTS

Controlling for socioeconomic status, measures of PA, decoding, and WID were higher for MAE than for NMAE speakers. There was no difference in stress accuracy between the dialect groups. Only for the NMAE group were PA and MA significantly related to decoding and WID. Stress accuracy was correlated with word reading for the NMAE speakers and with all measures for the MAE speakers.

CONCLUSION

Stress accuracy was consistently related to reading measures, even when PA and MA were not. Morphophonology involving suprasegmental factors may be an area of convergence between language varieties because of its consistent relationship to word reading.

How Grammatical Are 3-Year-Olds?

Purpose

This study investigated the level of grammatical accuracy in typically developing 3-year-olds and the types of errors they produce.

Method

Twenty-two 3-year-olds participated in a picture description task. The percentage of grammatical utterances was computed and error types were analyzed.

Results

The mean level of grammatical accuracy in typical 3-year-olds was ∼71%, with a wide range of variability. The current study revealed a variety of error types produced by 3-year-olds, most of which were produced by fewer than 5 children. The pattern observed for most of the children was to produce a scattering of errors with no more than a few of any 1 error type.

Conclusion

The level of grammatical accuracy in 3-year-olds was skewed toward the high end. Although tense marking errors were the most frequent error type, they accounted for only 1/3 of the errors produced by 3-year-olds. A more general measure of grammaticality that considers additional aspects of language might, therefore, be useful in assessing language at this age.

A Comparison of Oral and Written English Styles in African American Students at Different Stages of Writing Development

Purpose

The purpose of this investigation was to compare the rates of using African American English (AAE) grammatical features in spoken and written language at different points in literacy development. Based on Kroll’s model (1981), a high degree of similarity in use between the modalities was expected at Grade 3, and lower similarity was expected at Grade 8.

Method

Spoken and written language samples were analyzed for the occurrence of 6 AAE morphosyntactic features. Fifteen third graders and 15 eighth graders were asked to respond to interview questions and to retell stories in both modalities. Percentage use of the AAE grammatical features and a dialectal density measure were used to measure rates of AAE occurrence.

Results

Findings indicated comparable use of dialect in spoken and written modalities for 3 rd graders, but a difference in use between the modalities for 8 th graders. The 8 th graders used more dialectal features in speaking than writing.

Conclusion

These results suggest that there is likely a period in writing development when speakers of AAE learn to dialect switch in their writing.

Auxiliary BE production by African American English-speaking children with and without specific language impairment

PURPOSE

To examine 3 forms (am, is, are) of auxiliary BE production by African American English (AAE)-speaking children with and without specific language impairment (SLI).

METHOD

Thirty AAE speakers participated: 10 six-year-olds with SLI, 10 age-matched controls, and 10 language-matched controls. BE production was examined through samples and a probe.

RESULTS

Across tasks, visual inspection suggested that the children with SLI overtly marked BE at lower rates than the controls, and all groups marked am at higher rates than is and are, with few dialect-inappropriate errors. Within the samples, the children also overtly marked is at higher rates when preceded by it/that/what than when it was preceded by a personal pronoun. A subset of these results was confirmed statistically. The children's marking of BE also varied across tasks; for the age-matched controls, this variation was tied to their AAE dialect densities.

CONCLUSIONS

These findings show across-dialect similarities and differences between children's acquisition of AAE and mainstream American English. Similarities involve the rate of the children's BE marking as a function of their clinical status and the nature of their dialect-inappropriate errors. Differences involve the children's rates of BE marking as a function of the form, context, and task.

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.

African American English dialect and performance on nonword spelling and phonemic awareness tasks

PURPOSE

To evaluate the role of dialect on phonemic awareness and nonword spelling tasks. These tasks were selected for their reliance on phonological and orthographic processing, which may be influenced by dialect use.

METHOD

Eighty typically developing African American children in Grades 1 and 3 were first screened for dialect use and then completed a standardized test of phonological processing and a nonword spelling measure. The influence of dialect was analyzed in both experimental tasks, followed by a qualitative analysis of dialect use in nonword spellings.

RESULTS

Dialect density measures based solely on the use of African American English (AAE) phonological features explained few differences in phonological processing scores. In contrast, correlations indicated that children with higher dialect densities produced more nonword spelling errors influenced by AAE, an effect most evident in Grade 3. Qualitative analyses revealed AAE phonological features occurring in many of the misspelled nonwords.

CONCLUSION

After Grade 2, nonword spelling may be more sensitive to the effects of dialect variation than are phonemic awareness tasks. It is suggested that spelling may be a more sensitive clinical indicator of difficulties in integrating the phonological and orthographic information needed for fluent decoding skill.

African American preschoolers' language, emergent literacy skills, and use of African American English: a complex relation

PURPOSE

This study examined the relation between African American preschoolers' use of African American English (AAE) and their language and emergent literacy skills in an effort to better understand the perplexing and persistent difficulties many African American children experience learning to read proficiently.

METHOD

African American preschoolers' (n = 63) vocabulary skills were assessed in the fall and their language and emergent literacy skills were assessed in the spring. The relation between students' AAE use and their vocabulary and emergent literacy skills was examined using hierarchical linear modeling (HLM), controlling for fall vocabulary and other child, family, and school variables. Children's use of AAE was examined across two contexts-sentence imitation and oral narrative using a wordless storybook prompt.

RESULTS

There was a significant -shaped relation between the frequency with which preschoolers used AAE features and their language and emergent literacy skills. Students who used AAE features with greater or lesser frequency demonstrated stronger sentence imitation, letter-word recognition, and phonological awareness skills than did preschoolers who used AAE features with moderate frequency, controlling for fall vocabulary skills. Fewer preschoolers used AAE features during the sentence imitation task with explicit expectations for Standard American English (SAE) or School English than they did during an oral narrative elicitation task with implicit expectations for SAE.

CONCLUSIONS

The nonlinear relation between AAE use and language and emergent literacy skills, coupled with systematic differences in AAE use across contexts, indicates that some preschoolers may be dialect switching between AAE and SAE, suggesting emerging pragmatic/metalinguistic awareness.

The index of narrative microstructure: a clinical tool for analyzing school-age children's narrative performances

PURPOSE

This research was conducted to develop a clinical tool-the Index of Narrative Microstructure (INMIS)-that would parsimoniously account for important microstructural aspects of narrative production for school-age children. The study provides field test age- and grade-based INMIS values to aid clinicians in making normative judgments about microstructural aspects of pupils' narrative performance.

METHOD

Narrative samples using a single-picture elicitation context were collected from 250 children age 5-12 years and then transcribed and segmented into T-units. A T-unit consists of a single main clause and any dependent constituents. The narrative transcripts were then coded and analyzed to document a comprehensive set of microstructural indices.

RESULTS

Factor analysis indicated that narrative microstructure consisted of 2 moderately related factors. The Productivity factor primarily comprised measures of word output, lexical diversity, and T-unit output. The Complexity factor comprised measures of syntactic organization, with mean length of T-units in words and proportion of complex T-units loading most strongly. Principal components analysis was used to provide a linear combination of 8 variables to approximate the 2 factors. Formulas for calculating a student's performance on the 2 factors using 8 narrative measures are provided.

CONCLUSIONS

This study provided a method for professionals to calculate INMIS scores for narrative Productivity and Complexity for comparison against field test data for age (5- to 12-year-old) or grade (kindergarten to Grade 6) groupings. INMIS scores complement other tools in evaluating a child's narrative performance specifically and language abilities more generally.

Comprehension of third person singular /s/ in AAE-speaking children

PURPOSE

This investigation examined the comprehension of third person singular /s/ in 30 African American English (AAE)-speaking children as a subject-number agreement marker on a comprehension task.

METHOD

A comprehension task was presented to 30 typically developing AAE-speaking children between the ages of 4 and 6. The children were randomly assigned to 1 of 2 groups to hear prerecorded counterbalanced stimuli. The comprehension task was designed to mask plurality of subject; therefore, the children had to focus on the verb as an indicator of subject number.

RESULTS

Repeated measure analysis revealed that AAE-speaking children in this investigation did not understand third person singular /s/ as a number agreement marker. An additional analysis, d' (pronounced "d prime"), indicated that the AAE-speaking children are not sensitive to the third person singular /s/ as a clue to subject number.

CLINICAL IMPLICATIONS

The inclusion of comprehension tasks of third person singular /s/ to help diagnose language impairment in this population may be problematic.

It is not just the poor kids: the use of AAE forms by African-American school-aged children from middle SES communities

This study examined the production of African-American English (AAE) forms produced by 69 school-aged African-American children from middle socio-economic status (SES) communities to determine if age would influence: (a) the number of different types of AAE tokens and (b) the rate of dialect. Descriptive data revealed that there were more than 20 AAE morpho-syntactic forms collectively used by the children. The findings also indicated that factors of age, gender, and sampling context interacted in a variety of ways to influence these children's production of the number of different types of AAE tokens, and the rate of dialect.

LEARNING OUTCOMES

Readers should have (1) an increased awareness about the use of AAE forms in school-age children from middle SES homes; (2) a greater understanding of how the production of AAE might be influenced by age, gender, and sampling context.

A language screening protocol for use with young African American children in urban settings

Language screenings represent an important tool for early identification of language impairments in young children between 3 and 5 years of age. This investigation examined the utility of a well-established set of assessment measures for screening young African American children. One hundred and ninety-six children participated in the screening. Based upon the outcomes of the screening, 25 children who failed and a random sample of 56 children who passed were administered a larger language and cognitive assessment battery. Sensitivity and specificity of the screening were determined to be high. The number of different words, the Kaufman Nonverbal Scale, and nonword repetition accounted for a significant amount of the variance in performance. The screening is brief, valid, and culturally fair for use with preschool- and kindergarten-aged African American children living in urban settings.

Variable production of African American English across oracy and literacy contexts

Many African American students produce African American English (AAE) features that are contrastive to Standard American English (SAE). The AAE-speaking child who is able to dialect shift, that is, to speak SAE across literacy contexts, likely will perform better academically than the student who is not able to dialect shift.

METHOD

This investigation examined the AAE productions of 50 typically developing African American third graders across three language contexts-picture description, oral reading of SAE text, and writing.

RESULTS

All participants produced AAE during picture description. A downward shift in contrastive AAE features was evident between spoken discourse and the literacy contexts. More students produced more AAE features during picture description than writing. Both morphosyntactic and phonological features characterized the picture description context. Phonological features predominated during oral reading. In contrast, morphosyntactic features were the most dominant feature in writing.

CLINICAL IMPLICATIONS

The findings are discussed in terms of dialect-shifting abilities of African American students and the role of writing as a special context to support their entry into dialect shifting.

Familiarity With School English in African American Children and Its Relation to Early Reading Achievement

For children whose everyday speech differs greatly from the School English (SE) they encounter in academic materials and settings, it was hypothesized that greater familiarity with SE would be associated with more successful early reading acquisition. Sentence imitation and reading skills of 217 urban African American students in kindergarten through second grade (ages 5 to 8 years) were assessed. Children in each grade varied widely in the extent to which their imitations of SE sentences included phonological and grammatical forms that are acceptable in African American Vernacular English but not in SE. Higher familiarity with SE (reproducing SE features more often when imitating) was associated with better reading achievement, and these relationships were independent of memory ability.

Standardized assessment of phonological awareness skills in low-income African American first graders

Accurate identification of students with poor phonological awareness skills is important to providing appropriate reading instruction. This is particularly true for segments of the population, such as African American students, who have a history of reading failure. The purpose of this study was to examine the performance of a group of African American first-grade students from low-income families on a standardized test of phonological awareness. Fifty-six African American first graders were given the Test of Phonological Awareness (TOPA; J. K. Torgesen and B. R. Bryant, 1994). Mean student performance on the TOPA was significantly below expected norms and negatively skewed. However, students' mean performance on a test of basic reading skills indicated performance within normal limits. Outcomes are discussed relative to the validity and predictive power of standardized phonological assessment instruments, in this case, the TOPA, for use with African American students and the possible influence of dialect on performance.

Performance of Elementary-Grade African American Students on the Gray Oral Reading Tests

Purpose: African American students perform disproportionately more poorly on standardized reading assessments than their majority peers. Poor reading performances may be related to test biases inherent in standardized reading instruments. The purpose of this investigation was to examine the appropriateness of the Gray Oral Reading Tests-Third Edition (GORT-3; Wiederholt & Bryant, 1992) for assessing the reading abilities of elementary-grade African American students.

Method: Performances of 65 typically developing African American second through fifth graders were examined on the GORT-3.

Results: African American English (AAE) was produced by most students while reading passages from the GORT-3 that were written in Standard American English (SAE). A scoring correction for AAE resulted in a statistical improvement in the performance distributions, but this did not appear to be educationally significant. Measures of total feature production predicted reading accuracy and rate, but not comprehension.

Clinical Implications: Findings are discussed in terms of the appropriateness of this instrument for use by speech-language pathologists as they contribute to curricular and classroom placement decisions in schools with large numbers of typically developing African American students.

Comparison of conversation, freeplay, and story generation as methods of language sample elicitation

The spontaneous language sample forms an important part of the language evaluation protocol (M. Dunn, J. Flax, M. Sliwinski, and D. Aram, 1996; J. L. Evans and H. K. Craig, 1992; L. E. Evans and J. Miller, 1999) because of the limitations of standardized language tests and their unavailability in certain languages, such as Afrikaans. This study examined 3 methods of language elicitation, namely conversation (CV), freeplay (FP), and story generation (SG), on the following 5 measures to determine which method is best for clinical practice: number of utterances, variety of syntactic structures, mean length of the utterance (MLU), number of syntactic errors, and proportion of complex syntactic utterances as elicited from ten 5-year-old, Afrikaans-speaking boys. FP elicited significantly more utterances than did SG but elicited a smaller proportion of complex syntactic structures than did CV and SG. Furthermore, SG elicited longer utterances than did CV or FP. It is recommended that SG be used in clinical practice with 5-year-olds if the clinician wishes to observe maximum behavior. Where typical behavior is to be evaluated, the clinician can select a language elicitation method that best suits the client's personality and communication style, bearing in mind that FP does elicit a larger language sample.

Grade-related changes in the production of African American English

This investigation examined grade as a source of systematic variation in the African American English (AAE) produced by students in preschool through fifth grades. Participants were 400 typically developing African American boys and girls residing in low- or middle-income homes in an urban-fringe community or midsize central city in the metropolitan Detroit area. Between preschoolers and kindergartners, and between first through fifth graders, there were no significant differences in the amounts of dialect produced during a picture description language elicitation context. However, there was a significant downward shift in dialect production at first grade. Students who evidenced dialect shifting outperformed their nonshifting peers on standardized tests of reading achievement and vocabulary breadth.

Frameworks of Education: Perspectives of Southeast Asian Parents and Head Start Staff

PURPOSE

Interviews with Southeast Asian families and Head Start staff, participant observation of family and staff conferences, observations of teacher-child and parent-child interactions, and a review of all written Head Start information given to parents were used to gain information regarding how Southeast Asian parents, children, and Head Start staff make sense of early childhood education, their roles in child learning, and the identification of disabilities or learning problems.

METHODS

Nine Southeast Asian families and 10 children were participants. One Vietnamese and 3 EuroAmerican Head Start staff members participated in a series of two or three semistructured individual interviews. Additionally, 3 families were observed during scheduled conferences with Head Start staff. Each child was observed at Head Start during meals, center time, and outdoor play time. All literature routinely given to parents was analyzed. Ethnomethodology (the study of how participants make sense of their world) was used in collection and analysis of the data. The constructs of organizational culture (Schein, 1987, 1992), independence/interdependence, and power/distance relationships were used to help to make sense of the data themes.

CLINICAL IMPLICATIONS

Both families and staff were unaware of differences in their beliefs and values in the areas of education, parenting, child learning, and disability, which led to confusion and misunderstanding. All early childhood staff need to be aware of their underlying assumptions and how these may affect their interactions with children and families who may have different assumptions and expectations.

Phonological features of child African American English

The production of phonological features of African American English (AAE) was examined for 64 typically developing African American children in the 2nd through the 5th grade. Students read aloud passages written in Standard American English. Sixty of the students read the passages using AAE, and 8 different phonological features were represented in their readings. Phonological features were more frequent than morphosyntactic features. The findings as a whole support use of the taxonomy developed for this investigation in characterizing the phonological features of child AAE.

An assessment battery for identifying language impairment in African American children

This investigation compares the performances of 24 African American children, diagnosed as language impaired (LI) and receiving school-based language therapy, to 2 groups of typically developing peers (N = 48) on 5 traditional types of language assessment measures. Three of the measures were derived from child-centered free play language sample analyses and included average length of communication units (MLCU), frequencies of complex syntax, and numbers of different words. Two of the measures examined language comprehension and included responses to requests for information in the form of Wh-questions and responses to probes of active and passive sentence constructions. The performances of the group of children with language impairments were significantly lower on each measure than that of chronological age matched African American children who were typically developing. Sensitivity and specificity of the battery appeared excellent. The findings are discussed in terms of the potential of these informal language measures to contribute to a culturally fair assessment protocol for young African American children.
