Language Comprehension Scores Research Articles

How congruent are parent reports on 3-4-year-old children's language skills with other sources of data?

Parental report measures such as the MacArthur-Bates Communicative Development Inventories (CDIs) are frequently used to study communicative skills of children under 3 years of age. Less is known about the usability of such reports for assessing communication skills in older children due to their advanced language skills, and a higher variety of communicative partners and communication contexts. To assess the concurrent and predictive validity of the Estonian (E) CDI-III at ages 3;0 and 4;0 years. The first research goal was to examine its concurrent variability-associations with teacher reports and directly measured language skills. The second goal of the study was to investigate the predictive validity of parent reports-the degree to which parent-and teacher-reported language scores for children at age 3;0 are useful for predicting examiner-administered language comprehension and production scores 1 year later. Estonian monolingual children were investigated longitudinally at ages 3;0 (n = 104; M age = 35.77 months, SD = 0.84; 42% males) and 4;0 (n = 87; M age = 48.18 months, SD = 1.16; 42% males) years. Children were assessed with the parent-reported ECDI-III, with teacher-reported assessments on children's talkativeness, vocabulary size and grammatical skills, and the examiner-administered New Reynell Developmental Language Scales IV (NRDLS). Results indicated significant positive relationships between the ECDI-III total scores, teacher reports, and directly measured language comprehension and production scores, demonstrating concurrent validity of parental reports of children language skills at both ages. When controlling for mothers' education, children's gender, and reported language difficulties, parental and teacher reports were predictive of language production scores, whereas only parental reports predicted comprehension scores 1 year later. None of the controls was predictive of later language comprehension and production scores. In sum, good concurrent and predictive validity of the ECDI-III shows that the instrument is a valid tool for assessing communicative skills in Estonian children. Results suggest that parent reports can offer useable information also about communicative skills of children older than three years.

Relative heritage language and majority language use before school start explains variance in 2nd grade majority language but not reading skills.

The present study examined whether parents' and bilingual children's own relative use of the heritage language vs. the majority language in the homes of bilingual children in Denmark before school start explains variance in 2nd grade majority language skills and reading skills. The study included two groups of children: the Mixed bilinguals group (defined by having a native Danish and a nonnative parent, N = 376) and the Heritage bilinguals group (defined by having parents who were both speakers of a Heritage language, N = 276). Four-stage hierarchical regression analyses showed that, after accounting for type of bilingualism, socioeconomic status (SES) and home literacy environment quality, relative use of the heritage vs. the majority language explained variance in 2nd grade Danish language comprehension scores, but did not explain variance in two reading scores, namely decoding and reading comprehension. In addition, a home literacy factor denoting book exposure (number of books, frequency of reading, library visits, and age of beginning shared book reading) was a significant predictor of both 2nd grade language and reading outcomes, whereas SES became a nonsignificant predictor when adding home literacy and language use predictors. We interpret the results to mean that parents' and the child's own relative use of the heritage language vs. the majority language before school start does not influence bilingual children's early reading skills, whereas a supportive early home literacy environment is a positive predictor of reading skills independently of SES and parental majority language use and skill.

A Short and Engaging Adaptive Working-Memory Intervention for Children with Developmental Language Disorder: Effects on Language and Working Memory.

Recent research has suggested that working-memory training interventions may benefit children with developmental language disorder (DLD). The current study investigated a short and engaging adaptive working-memory intervention that targeted executive skills and aimed to improve both language comprehension and working-memory abilities in children with DLD. Forty-seven 6- to 10-year-old children with DLD were randomly allocated to an executive working-memory training intervention (n = 24) or an active control group (n = 23). A pre-test/intervention/post-test/9-month-follow-up design was used. Outcome measures included assessments of language (to evaluate far transfer of the training) and working memory (to evaluate near transfer of the training). Hierarchical multiple regression analyses controlling for pre-intervention performance and age found the group to be a significant predictor of sentence comprehension and of performance on six untrained working-memory measures at post-intervention and 9-month follow-up. Children in the intervention group showed significantly higher language comprehension and working-memory scores at both time points than children in the active control group. The intervention programme showed the potential to improve working memory and language comprehension in children with DLD and demonstrated several advantages: it involved short sessions over a short period, caused little disruption in the school day, and was enjoyed by children.

‘Moderate global aphasia’: A generalized decline of language processing caused by glioma surgery but not stroke

Unlike stroke, neurosurgical removal of left-hemisphere gliomas acts upon a reorganized language network and involves brain areas rarely damaged by stroke. We addressed whether this causes the profiles of neurosurgery- and stroke-induced language impairments to be distinct. K-means clustering of language assessment data (neurosurgery cohort: N = 88, stroke cohort: N = 95) identified similar profiles in both cohorts. But critically, a cluster of individuals with specific phonological deficits was only evident in the stroke but not in the neurosurgery cohort. Thus, phonological deficits are less clearly distinguished from other language deficits after glioma surgery compared to stroke. Furthermore, the correlations between language production and comprehension scores at different linguistic levels were more extensive in the neurosurgery than in the stroke cohort. Our findings suggest that neurosurgery-induced language impairments do not correspond to those caused by stroke, but rather manifest as a ‘moderate global aphasia’ – a generalized decline of language processing abilities.

Neuropsychological correlates of evocative multimodal speech: The combined roles of fearful prosody, visuospatial attention, cortisol response, and anxiety

Past research reveals left-hemisphere dominance for linguistic processing and right-hemisphere dominance for emotional prosody processing during auditory language comprehension, a pattern also found in visuospatial attention studies where listeners are presented with a view of the talker’s face. Is this lateralization pattern for visuospatial attention and language processing upheld when listeners are experiencing a stress response? To investigate this question, participants completed the Trier Social Stress Test (TSST) between administrations of a visuospatial attention and language comprehension dual-task paradigm. Subjective anxiety, cardiovascular, and saliva cortisol measures were taken before and after the TSST. Higher language comprehension scores in the post-TSST neutral prosody condition were associated with lower cortisol responses, differences in blood pressure, and less subjective anxiety. In this challenging task, visuospatial attention was most focused at the mouth region, both prior to and after stress induction. Greater visuospatial attention on the left side of the face image, compared to the right side, indicated greater right hemisphere activation. In the Fear, but not the Neutral, prosody condition, greater cortisol response was associated with greater visuospatial attention to the left side of the face image. Results are placed into theoretical context, and can be applied to situations where stressed listeners must interpret emotionally evocative language.

Visual Sequence Repetition Learning is Not Impaired in Signing DHH Children.

The auditory scaffolding hypothesis states that early experience with sound underpins the development of domain-general sequence processing abilities, supported by studies observing impaired sequence processing in deaf or hard-of-hearing (DHH) children. To test this hypothesis, we administered a sequence processing task to 77 DHH children who use American Sign Language (ASL) and 23 hearing monolingual children aged 7-12years and found no performance difference between them after controlling for age and nonverbal intelligence. Additionally, neither spoken language comprehension scores nor hearing loss levels predicted sequence processing scores in the DHH group, whereas ASL comprehension scores did. Our results do not indicate sequence processing deficits in DHH children and do not support the auditory scaffolding hypothesis; instead, these findings suggest that factors related to experience with and/or proficiency in an accessible language during development may be more important determinants of sequence processing abilities.

Is silence golden? A pilot study exploring associations between children’s language environment and their language skills in Estonian-speaking families

This two-wave longitudinal study explored how Estonian children’s language environment relates to their language skills. The Language ENvironment Analysis (LENA) system’s automated measures were used as a source of information about children’s home language environment. Children’s expressive vocabulary was measured via the parent-reported Estonian CDI III (ECDI-III), and language comprehension and production were measured via the examiner-administered New Reynell Developmental Language Scales (NRDLS). The assessments were made 1 year apart at ages 3;0 (years; months) (N = 22) and 4;0 (N = 19). The results revealed wide variability in children’s home language environment and language skills. Girls’ language production scores were higher; they heard a larger quantity of adult words and spent less time in noisy environments than boys at Wave 2. At Wave 1, children’s word count was positively associated with productive language scores, whereas silence was negatively associated with language production and expressive vocabulary. At Wave 2, children who had been more exposed to electronic media scored higher on expressive vocabulary. Distant speech at Wave 1 was positively correlated with language comprehension scores at Wave 2 also when controlling for language comprehension scores at Wave 1. The results, which indicate that distant talk is a positive aspect and silence is a negative aspect of the language environment, highlight the importance of “languagizing” homes also in cultures where silence tends to be more highly valued and talkativeness tends to be less highly valued when compared with English-speaking middle-class families.

How statistical learning interacts with the socioeconomic environment to shape children's language development.

Language is acquired in part through statistical learning abilities that encode environmental regularities. Language development is also heavily influenced by social environmental factors such as socioeconomic status. However, it is unknown to what extent statistical learning interacts with SES to affect language outcomes. We measured event-related potentials in 26 children aged 8-12 while they performed a visual statistical learning task. Regression analyses indicated that children's learning performance moderated the relationship between socioeconomic status and both syntactic and vocabulary language comprehension scores. For children demonstrating high learning, socioeconomic status had a weaker effect on language compared to children showing low learning. These results suggest that high statistical learning ability can provide a buffer against the disadvantages associated with being raised in a lower socioeconomic status household.

Interhemispheric interactions during sentence comprehension in patients with aphasia

Right-hemisphere involvement in language processing following left-hemisphere damage may reflect either compensatory processes, or a release from homotopic transcallosal inhibition, resulting in excessive right-to-left suppression that is maladaptive for language performance. Using fMRI, we assessed inter-hemispheric effective connectivity in fifteen patients with post-stroke aphasia, along with age-matched and younger controls during a sentence comprehension task. Dynamic Causal Modeling was used with four bilateral regions including inferior frontal gyri (IFG) and primary auditory cortices (A1). Despite the presence of lesions, satisfactory model fit was obtained in 9/15 patients. In young controls, the only significant homotopic connection (RA1-LA1), was excitatory, while inhibitory connections emanated from LIFG to both left and right A1's. Interestingly, these connections were also correlated with language comprehension scores in patients. The results for homotopic connections show that excitatory connectivity from RA1-to-LA1 and inhibitory connectivity from LA1-to-RA1 are associated with general auditory verbal comprehension. Moreover, negative correlations were found between sentence comprehension and top-down coupling for both heterotopic (LIFG-to-RA1) and intra-hemispheric (LIFG-to-LA1) connections. These results do not show an emergence of a new compensatory right to left excitation in patients nor do they support the existence of left to right transcallosal suppression in controls. Nevertheless, the correlations with performance in patients are consistent with some aspects of both the compensation model, and the transcallosal suppression account for the role of the RH. Altogether our results suggest that changes to both excitatory and inhibitory homotopic and heterotopic connections due to LH damage may be maladaptive, as they disrupt the normal inter-hemispheric coordination and communication.

Longitudinal growth of receptive language in children with cerebral palsy between 18 months and 54 months of age.

We examined receptive language developmental trajectories between 18 months and 54 months for three clinical speech-language profile groups of children with cerebral palsy (those with speech motor involvement, without speech motor involvement, and with anarthria) and quantified differences from age-level expectations. We identified latent classes of comprehension development, related these classes to clinical profile groups, and examined how well early receptive language predicted outcomes. We used a prospective longitudinal design. Eighty-five children with cerebral palsy (43 females, 42 males) were followed longitudinally from 18 to 54 months of age. Children were seen two to eight times (322 data points). Children were classified into clinical profile groups. Language comprehension age-equivalent scores were the primary measures of interest. Children with anarthria had significant language delays, limited developmental change over time, and comprised their own latent class. Children with speech motor impairment had slight receptive language delays over time. Children with no speech motor impairment had age-appropriate receptive language over time. Early language comprehension scores were highly predictive of later latent profile group membership. Early language comprehension abilities are highly predictive of language comprehension growth trajectory and suggest that children with early language delay, particularly those who are non-speaking, should receive language intervention to support development. There are two growth trajectories for language comprehension among children with cerebral palsy. Children with speech motor impairment had a constant 6-month receptive language delay. Children without speech motor impairment had age-appropriate receptive language. Non-speaking children had significant receptive language delay. Early language comprehension change was highly predictive of later trajectory group.

The effect of read-aloud assistance on the text comprehension of dyslexic and non-dyslexic English language learners

One of the special arrangements in testing contexts is to allow dyslexic students to listen to the text while they read. In our study, we investigated the effect of read-aloud assistance on young English learners’ language comprehension scores. We also examined whether students with dyslexia identification benefit from this assistance differently from their peers with no official identification of dyslexia.Our research was conducted with young Slovenian learners of English who performed four language assessment tasks adapted from a standardized battery of Slovenian national English language tests. In a counter-balanced design, 233 students with no identified dyslexia and 47 students with dyslexia identification completed two language comprehension tasks in a reading-only condition, one task with read-aloud assistance and one task in listening-only mode. We used Generalized Linear Mixed-Effects Modelling (GLMM) to estimate accurately the effects of the mode of administration, dyslexia status, and input text difficulty, while accounting for error variance owing to random differences between students, texts, and questions.The results of our study revealed that young L2 learners with no dyslexia identification performed similarly in the three conditions. The read-aloud assistance, however, was found to increase the comprehension scores of dyslexic participants when reading difficult texts, allowing them to perform at the level of their non-dyslexic peers. Therefore, our study suggests that this modification of the test administration mode might assist dyslexic students in demonstrating their text comprehension abilities.

Personality Traits of Profoundly Hearing Impaired Adolescents with Cochlear Implants - A Comparison with Normal Hearing Peers.

The aim of this study was to compare the personality traits of adolescents with cochlear implants (CIs) to a reference group (normal-hearing peers). In the past, the personality development of hearing impaired adolescents was severely compromised. Improved speech perception with CI significantly increased their perspectives. In addition, differences between the reference group and CI users were investigated on personality traits according to level of speech perception skills (high/low) and level of language comprehension (adequate/poor). A cohort of 59 adolescents was assessed 10 years after CI implantation. Personality traits were measured using the standardized Dutch Personality Questionnaire, which consists of 5 scales: Inadequacy, Social Inadequacy, Recalcitrance (RE), Perseverance, and Dominance. Speech perception and language comprehension were tested with standardized tests. The distributions of personality scores, in the clinical or non-clinical range, for the CI group were compared to the reference group using the Chi-Square test for Goodness of Fit. Adolescents with CI showed normal or favorable distributions on all personality scales except for the RE scale. There was a significant influence of speech perception and language comprehension on this scale. Consequently, adolescents with CI who demonstrated high speech perception and adequate language comprehension scores showed similar distribution patterns as the reference group on all personality scales. In conclusion; personality traits that reflect social relations, self-conscience, and school- and task orientation in adolescents with CI are similar to those in normal-hearing peers. This holds, despite variations in speech perception ability and language comprehension levels, for the CI group. On the RE scale, the adolescents with CI with low speech perception and poor language comprehension scores are more likely to score in the clinical deviant range and are at risk.

Right Hemisphere Grey Matter Volume and Language Functions in Stroke Aphasia.

The role of the right hemisphere (RH) in recovery from aphasia is incompletely understood. The present study quantified RH grey matter (GM) volume in individuals with chronic stroke-induced aphasia and cognitively healthy people using voxel-based morphometry. We compared group differences in GM volume in the entire RH and in RH regions-of-interest. Given that lesion site is a critical source of heterogeneity associated with poststroke language ability, we used voxel-based lesion symptom mapping (VLSM) to examine the relation between lesion site and language performance in the aphasic participants. Finally, using results derived from the VLSM as a covariate, we evaluated the relation between GM volume in the RH and language ability across domains, including comprehension and production processes both at the word and sentence levels and across spoken and written modalities. Between-subject comparisons showed that GM volume in the RH SMA was reduced in the aphasic group compared to the healthy controls. We also found that, for the aphasic group, increased RH volume in the MTG and the SMA was associated with better language comprehension and production scores, respectively. These data suggest that the RH may support functions previously performed by LH regions and have important implications for understanding poststroke reorganization.

Cognitive deficits revealed with the Rus-BCoS and their relationships with language comprehension in fluent and nonfluent aphasia

EP 6. Longitudinal resting state functional connectivity patterns in the early phase of recovery from Aphasia in temporoparietal stroke

Background Poststroke aphasia recovery evolves in space and time. Substantial language improvements can be observed within the first days after stroke. However, underlying changes in the functional status of the language network during the acute phase remain to be demonstrated. Methods In a resting-state functional connectivity (RSFC) fMRI study we assessed changes in functional connectivity repeatedly (acute( t 1) = 2 ± 1, subacute( t 2) = 10 ± 2 days post-onset) in aphasic patients ( N = 12, 62 ± 14 years, 10 male) with left temporoparietal stroke. Language comprehension and production scores were calculated based on the Aachener Aphasie-Test. For RSFC analysis 9mm spherical ROIs reflecting core language regions in the left anterior inferior frontal (aIFG: x = −54 y = 32 z = 1, MNI-space), posterior middle temporal gyrus (pMTG: x = −54 y = −43 z = 4) and their right hemisphere homologous were selected. Results Seed-to-whole-brain analysis from left aIFG or pMTG revealed RSFC to right hemisphere homologous frontal or temporal areas at t 1 and t 2 ( p > .05, FWE corrected). Longitudinally, RSFC from left pMTG to left aIFG as well as RSFC from left aIFG to left frontal (operculum, insula, premotor cortex) and to right frontal (IFG, premotor cortex) areas increased significantly from t 1 to t 2 ( p > .001, uncorrected). Subsequent ROI-to-ROI analysis revealed increased RSFC between left aIFG and pMTG from t 1 to t 2 associated with improved language production ( r = .579, p = .049). During the acute phase ( t 1) better scores for language comprehension and production were predicted by higher RSFC between left aIFG and right aIFG ( r = .736 p = .006). Conclusion We observed early ipsi- and contralesional changes in the language network’s functional connectivity and associated language improvements indicative of acute diaschisis and subsequent reorganization within the distributed language network.

Minimal pair word learning and vocabulary size: Links with later language skills

ABSTRACTThere is increasing interest in the link between early linguistic skills and later language development. In a longitudinal study, we investigated infants’ (a) ability to use speech sound categories to guide word learning in the habituation-based minimal pair switch task, and (b) early productive vocabulary, related to their concurrent and later language task performance. The participants at Phase 1 were 64 infants aged 16–24 months (25 with familial risk of language/speech impairment), followed up at 27 months (Phase 2) and at 3 years (Phase 3). Phase 1 productive vocabulary was correlated with Phase 2 productive vocabulary, and with concurrent and later (Phase 3) tests of language production and comprehension scores (standardized tool), and phonology. Phase 1 switch task performance was correlated with concurrent productive vocabulary and language production scores, but not by Phase 3. However, a combination of early low vocabulary score and a preference for looking at an already-habituated word–object combination in the switch task may show some promise as an identifier for early speech–language intervention. We discuss how these relations can help us better understand the foundations of word learning.

Using Podcasts to Improve Second Language Comprehension in Iranian Language Classrooms

<p>The present study aims at investigating the influence of podcasts (POD) on language comprehension of Iranian pre-intermediate EFL learners. An Oxford Placement Test (OPT) was administered to 60 male and female university students. The participants were considered as pre-intermediate learners and were divided into two groups (one experimental group and one control group). During the fifteen sessions of the treatment, thirty podcasts were presented to the two groups. The experimental group received just the audio file of the POD, and the control group received a different treatment which was the transcript file of the same audio podcast file of the experimental group. The results of the t-tests revealed that there was no significant difference in language comprehension scores across the posttest between two groups. Based on the interview results after the post-test, all of the participants (100%) agreed that both audio and the transcripts (written texts) were useful for them and claimed that it is a good method of improving language comprehension.</p>

Semantic processing of actions at 9 months is linked to language proficiency at 9 and 18 months

The current study uses event-related potential methodologies to investigate how social–cognitive processes in preverbal infants relate to language performance. We assessed 9-month-olds’ understanding of the semantic structure of actions via an N400 event-related potential (ERP) response to action sequences that contained expected and unexpected outcomes. At 9 and 18months of age, infants’ language abilities were measured using the Swedish Early Communicative Development Inventory (SECDI). Here we show that 9-month-olds’ understanding of the semantic structure of actions, evidenced in an N400 ERP response to action sequences with unexpected outcomes, is related to language comprehension scores at 9months and is related to language production scores at 18months of age. Infants who showed a selective N400 response to unexpected action outcomes are those who are classed as above mean in their language proficiency. The results provide evidence that language performance is related to the ability to detect and interpret human actions at 9months of age. This study suggests that some basic cognitive mechanisms are involved in the processing of sequential events that are shared between two conceptually different cognitive domains and that pre-linguistic social understanding skills and language proficiency are linked to one another.

Relationship between social interaction bids and language in late talking children

Purpose: The aim of this paper is to explore the relationship between language development and the frequency of social interaction (SI) behaviours during language acquisition in late-talking (LT) children who exhibit delays in expressive vocabulary development but have age-appropriate cognitive skills.Method: The research consists of a longitudinal study with a first test followed by two re-tests 5 months apart, in which LT children were compared to 5-months-younger typically-developing (TD) children.Result: Data showed that LT children performed significantly fewer initiation of SI behaviours, but no differences between groups in responding to SI behaviours were observed. Furthermore, LT children who have lower language comprehension scores initiate social interaction more frequently.Conclusion: The results showed that LT children seem to be less active in starting social interaction and participation, but, once they get involved, they respond similarly to TD children of comparable expressive language competence. Additionally, the correlation pattern between the frequency of SI behaviours and language functions showed that LT toddlers with more prominent receptive language delay are more interested in initiating interaction with their partner, thus suggesting that they need a partner's “scaffolding” to overcome this lack.

Promoting factors of physical and mental development in early infancy: a comparison of preterm delivery/low birth weight infants and term infants

The aim of this study was to assess correlations between various factors and the physical and mental development of 4-month-old infants using a multi-faceted evaluation approach. A total of 1,402 self-administered questionnaires were distributed to consenting mothers of infants who had undergone a 4-month health checkup in Hiroshima prefecture, Japan. The questionnaires included items from the Japan Child and Family Research Institute Child Rearing Support Questionnaire and the KIDS type A test. Of the 421 completed questionnaires on mother-child pairs that were returned, 318 met the inclusion criteria and were eligible for further analysis. Comparison between infants in a preterm delivery or low birth weight (LBW) group (preterm and/or LBW group; n=31) and a term delivery appropriate-weight for date (AFD) infant group (term AFD group; n =287) revealed that the preterm and/or LBW group had significantly higher mother child-rearing anxiety and difficult baby scores, along with significantly lower infant development and motor skill scores. Within the term AFD group, infants of primiparous mothers had significantly higher scores for motor skill and sociability with adults than those of multiparous mothers. Language comprehension scores were significantly higher in infants that were exclusively breast-fed than those formula-fed or combined breast-fed and formula-fed. Verbalization scores of infants whose mothers worked were significantly higher than those of infants whose mothers did not work. Infants with siblings aged <4years exhibited significantly lower scores for motor skills, verbalization, and sociability with adults than infants without siblings or with siblings aged at least 5years. In particular, we found that a mother's child-rearing anxiety was related to many areas of infant development. Evaluating the absence or presence of such factors and conducting preventive treatment could promote healthy infant development.
