complex syntax development

All commenters must hold a formal affiliation as per our Policies. If applicable, is the statistical analysis and its interpretation appropriate? To reduce the likelihood of floor effects additional practice items were given when administering this subtest. To avoid floor effects only those with a non-verbal mental age of 3;06 years and above on the Leiter International Performance Scale 3rd Edition (Leiter-3) (Roid et al., 2013) were included and children were required to be capable of producing 3-word utterances at a minimum. However, this format is likely to lead to children failing for reasons other than a lack of linguistic knowledge. A description of each of the animations is available in Supplementary File 1. The probability of scoring 7 or more correct by guessing was computed by the binomial theorem as p < 0.036. They can now be found at the top of the panel on the right, linked from the box entitled Open Peer Review. The parameter estimates from the final model (Table 6) can be found in Table 7. However, we also expected to be able to drop one predictor, depending on the results of our first analysis. 1997. The parameter estimates from the final model (Table 4) can be found in Table 5. Participants were tested at 1000, 2000 and 4000 Hz. Thank you for inviting me to review this paper. Visuo-spatial memory was assessed using a version of the block recall test from the WMTB-C (Pickering & Gathercole, 2001) adapted for tablet presentation. on complex sentences. You expect to receive, or in the past 4 years have received, any of the following from any commercial organisation that may gain financially from your submission: a salary, fees, funding, reimbursements. In the teen years, your child should develop the ability to use more complex syntax and to adapt her oral and written communication to her audience, according to the U.S. Department of Education. There is the possibility of response bias when completing a task that requires a yes/no response, whereby the child may always give a ‘yes’ or ‘no’ response when they do not understand the construction presented. Individuals with DS show particular difficulties with verbal short-term or working memory tasks (Jarrold & Baddeley, 2010; Jarrold et al., 2002; Laws, 2002) even when compared to other groups with cognitive delay, who do not have DS (Bower & Hayes, 1994; Chapman, 2006; Laws, 2004). Discussion: If rich linguistic inputs are not available for children during the critical period of the first language acquisition, the syntactic skill, especially in complex syntactic constructions, will not normally develop. In addition, Chapman & Hesketh (2001) reported these factors to be key predictors of expressive syntax at the onset of their study. We then compared the two groups with intellectual disability and included age in the model with sentence verification as the dependent measure. If the participant changed their mind, a reset button allowed the administrator to re-enter the digits recalled. For the adverbial because, non-match items were represented by depicting the event as it was described by both verbs, but not causally (e.g. A number representing the real part of the complex number. Many studies of both language comprehension and production have been conducted in an attempt to account for the language difficulties observed in children with the condition. Previous studies have tended to use multiple-choice tasks that have a heavy cognitive load and make demands beyond the linguistic. Adverbial clauses included two temporal (before, after), one causal (because) and one conditional (if). Our current study aimed to investigate how well children with DS could understand complex sentences such as relative clauses, adverbial clauses and complement clauses. Hispania 81: 576-587.---. Learners of a language must know how to arrange words that they know to make a sentence.

Responses were stored and scored automatically on the tablet. References to our previous work explaining why we consider TECS-E to be a less demanding cognitive task. When complex syntax is involved, it has been in the context of standardized measures, in which different syntactic structures (both simple and complex) are grouped together and a composite score is reported (for example using The Test for Auditory Comprehension of Language-Revised (TACL-R) (Carrow-Woolfolk, 1985) or the Test for the Reception of Grammar (TROG-2) (Bishop, 2003). However, the children included in the current study are considerably older, ranging in age from 5;01 to 7;09 years and we therefore expect a more stable performance across relative clause types. Our third prediction was that children with Down syndrome would have greater difficulty understanding comparable constructions on the TROG-2 (a multiple-choice comprehension task), than on TECS-E. received more attention than the development of syntax; furthermore, existing studies on cL2 complex syntax examine comprehension rather than production (e.g., Unsworth, 2016). Someone in that situation is are more likely to say ‘yes’ than ‘no’ if they see a picture depicting all the components of the sentence, because it provides a good enough match to their patchy construction of meaning. However, to our knowledge, this has never been investigated in relation to this population. scientific mentor, recent student). The comparable constructions included in both tests were the intransitive subject relatives (attached to a main clause object). Alongside their report, reviewers assign a status to the article: speech, language and communication in children with Williams syndrome, Down syndrome. The written mode promotes the creation of complex syntactic units, as constructing a piece of written language imposes cognitive demands on memory, executive functions, and top-down processing that are not readily met before adolescence. Language has been argued to exhibit a complex system behavior. DOI: https://doi.org/10.17605/OSF.IO/X6UNE (Frizelle et al., 2018b). 2.1.1 Child speaks in single word utterances. This allowed us to identify whether those with DS have a characteristic syntactic profile relative to the other two groups. Complex syntax refers to developmentally advanced grammatical structures that mark a “literate,” or decontextualized, language style (Paul, 1995). 'Milk', 'Mummy' 2.2 Groups of words may be used as a single unit. Expository discourse, the use of language to convey information, requires facility with complex syntax. Complex syntax development begins in the preschool years. Using the TROG-2 as the receptive language measure, studies such as those by Finestack et al. Requests for access to the set of videos used in this study should be addressed to the corresponding author, with an explanation of why access to the videos is sought. We developed a new test (TECS-E: Test of Complex Syntax-Electronic) that was designed to minimise such demands by using a format where the child sees a specific animation and has to judge whether it matches a spoken sentence. For instance, the child might be shown a picture of a girl drinking and just be asked to say ‘yes’ or ‘no’ to the sentence ‘a horse is drinking’. In addition, we have found that children's performance on language comprehension tests can be heavily influenced by the specific demands of the assessment method employed (Frizelle et al., 2017). This block of four items uses relative clauses attached to a main clause object, similar to the sentence types used in the sentence verification task described below. Here, in order to compare test administrations between TECS-E and TROG-2, we always administered block S (relative clauses) from TROG-2 at the end of the test, even if the stopping criterion was reached. The main differences between this version and our original submission are as follows: See the authors' detailed response to the review by Nicola Botting See the authors' detailed response to the review by Vesna Stojanovik See the authors' detailed response to the review by Christopher Jarrold and Nikolitsa Stathopoulou. Hispania 78: 122-135.---. Classification is a sorting task that involves categorizing objects or geometric shapes (such as coloured circles) and sequential order requires the child to understand the relationship between shapes/blocks in order to find the missing elements at the end or in the middle of a series. Therefore, despite evidence of a disproportionate difficulty for people with DS in each of the two aforementioned studies, it is difficult to compare their results with those found in the current investigation. A number of studies have shown that expressive grammar in people with DS continues to develop throughout adolescence and possibly into adulthood (Chapman et al., 2002; Laws & Gunn, 2004), whereas those exploring syntactic comprehension report mixed findings; many suggesting that syntactic comprehension is likely to reach a plateau in late adolescence or even to decline with age (Chapman et al., 2002). In relation to the factors that would predict performance in children’s ability to understand complex sentences, our results, for the most part, are in line with what we predicted. Complete raw data for the study “The understanding of complex syntax in children with Down syndrome” is available on OSF. Predictors of children’s performance on TECS-E. Our next prediction related to the factors that were associated with children’s performance on TECS-E. We hypothesised that the ability of children with DS to understand complex sentences would be explicable in terms of their deficits in verbal short-term memory, working memory and hearing level. The relative clauses were all full bi-clausal relatives, each attached to the direct object of a transitive clause. Total scores were calculated for each child and for each construction type. The former is the more typical way that items are measured on span tests. (2002), there exist apparent differences in syntactic development among 3 to 5 year-old Cantonese-speaking children. In relation to complex syntax specifically, Thordardottir et al. The performance range of each group is illustrated in the plot at Figure 2. We compared strengths or weaknesses seen in those with DS to two other groups: (a) those with intellectual disability but of unknown aetiology (matched to those with DS on non-verbal mental age), and (b) a group of TD younger children at the same non-verbal mental age. A longitudinal study traced the development of the understanding of false belief and various measures of spontaneous language production and comprehension over the course of one year. PF conceived the study idea, designed the assessment tool and hypotheses, and wrote the manuscript, MD developed the software for the application assessment task TECS-E and the memory assessment tasks, PT developed scripts for power analysis and other aspects of the analysis, DB helped to develop the idea and the assessment tool, designed hypotheses, and reviewed the manuscript. A key question was whether the prediction of TROG-2 scores by the mental age and memory measures was better than prediction of TECS-E scores: to check this, we calculated the 95% confidence interval around the R2 values. 2) Those with DS will perform more poorly overall than TD controls but at a similar level to those with cognitive impairment of unknown origin. Finally, we anticipated that sentences using the verb pretend would be the least difficult complement clause items and that those using the cognitive state verb think would be the most difficult to understand. In our final hypothesis we predicted that cognitive and verbal memory abilities would account for more variance on the multiple-choice than on the sentence verification animated task. Cohen’s d values were calculated for each piece of metadata and then converted to f2 for use in the sample size calculation. Beginning with one and gradually increasing in number, monsters were revealed for a period of 4 seconds. TECS-E complex syntax comprehension task. For a more detailed discussion see Frizelle et al. This result is consistent with previous findings (see Finestack et al., 2013; Joffe & Varlokosta, 2009; Laws & Bishop, 2003; Pennington et al., 2003; Price et al., 2007; Rosin et al., 1988). Track an article to receive email alerts on any updates to this article. More recently, Christodoulou & Grohmann (2018) reported on the comprehension of syntactically complex subjunctives (e.g. Language difficulties in children with DS are well documented, particularly those affecting vocabulary, phonology, morphology, and simple sentence structures (Dodd & Thomspson, 2001; Eadie et al., 2002; Laws & Bishop, 2003; Price et al., 2007). This block of four items uses relative clauses attached to a main clause object, two of which are similar in construction to those used in the TECS-E (albeit with some lexical differences—a noun rather that a pronoun in the head noun position: The girl chases the dog that is jumping) and two of which incorporate prepositional phrases (The cup that is on the box is red). On the TROG- 2 (a multiple-choice comprehension task), both the DS and the CI group performed very poorly, with no children passing a block of items testing complex sentence comprehension; furthermore, only a minority of the TD children showed evidence of understanding these items. The current project examines global text structure, syntactic measures (word order, subordination, and coordination) and morpho-lexicon in two text genres – informative and expository – produced by children, adolescents, and adults with different linguistic proficiencies. Assessments were administered in a quiet room at the preschool, school or special school that each participant attended. Complement clauses are the earliest developing form of complex sentence (Diessel, 2004) and are often used with mental state verbs such as know and think. This was followed by the memory variables, which accounted for a further 67% of the variance in total TROG score (both p < 0.001). Memory assessments. The latter is evident in both receptive and expressive modalities (Abbeduto et al., 2003; Berglund et al., 2001; Chapman et al., 1991). Is the study design appropriate and is the work technically sound? I cannot comment. Processing Instruction and the subjunctive. Our pre-registered hypotheses https://osf.io/5ntvc/ were as follows: 1) Individuals with DS will be able to understand a range of the complex sentences tested, although we expect considerable individual variation. Participants listened to a target word or sentence and from a choice of four, they were required to identify the corresponding picture. The usual direction of effect posited between the development of concepts and the language that encodes them is, quite naturally, that the concepts develop before the corresponding terms. Data from PMC are received and updated monthly. Finally, the DS variable was entered into the model, accounting for a further 1.2% of the variance in children’s performance on this assessment. The DOI for each task is listed below. In addition, we calculated the 95% confidence interval around the R2 values in the regressions using the CI.Rsqlm function from the psychometric package in R. This was used to compare total explained variance of predictors in both dependent measures. This finding is also consistent with expressive acquisition data, (Diessel, 2004) showing that when children start to produce full bi-clausal relatives, the majority are of the intransitive subject form. (2002) analysed 12-minute narrative samples from 24 adolescents with DS (mean age 16.5 years) and a control group of younger TD children matched on mean length of utterance (MLU). favour or employment) as a result of your submission. In this analysis we calculated the proportion of children in each group that passed each construction on the sentence verification task (shown in Table 8), where a pass was defined as a score of 7 or 8 out of 8 items correct. Are the conclusions drawn adequately supported by the results? The addition of: 1) full statistical details for regressions 1 and 2 including the constant value; and 2) Cronbachs alpha as a measure of internal consistency. TROG-2 (Bishop, 2003) is a multiple choice sentence picture-matching task. The TACL-R also uses a multiple-choice sentence picture matching design, the implications of which are discussed below (see Multiple-Choice v’s Sentence Verification Task). 4) Cognitive ability, verbal memory, working memory and hearing level will predict performance in the DS group. This paper is particularly concerned with addressing the discrepancies between males and females regarding syntactic aspects of language. The term ‘complex sentence’ is used to refer to constructions that have more than one clause, linked in specific ways. No child from the DS or CI samples achieved this level of performance, and only five children (15%) from the TD group did this well. Contribution of parenting to complex syntax development in preschool children with developmental delays or typical development (2002) coupled with the fact that receptive language is usually superior to expressive, in this population (Chapman et al., 2002; Laws & Bishop, 2003). The Development of Complex Syntax and Mood-Selection Abilities by Intermediate-Level Learners of Spanish Joseph Collentine East Carolina University Abstract: Foreign language learners of Spanish seemingly cannot master mood selection-the indicative/ subjunctive distinction-by the end of the intermediate level of instruction (within four semesters). A comparison of those with DS and the two control groups (matched on non-verbal mental age). As shown by Tse et al. (2018a) found a consistent benefit for the sentence-verification method for young children, and we suggested this reflected the fact that sentences are presented in a manner more reflective of how we process language in natural discourse, with fewer processing and memory demands than in a multiple-choice test. These comparison groups were broadly equated to those with Down syndrome on a non-verbal measure of mental age. (2013), DS versus Fragile X; Joffe & Varlokosta (2009), DS versus William syndrome, and Laws & Bishop (2003), DS versus SLI, have reported a similar performance between each group pair. With respect to children with typical development, we can see that they performed near ceiling on all relative clause types. Default 0. Given the populations under scrutiny tend to have significant receptive language difficulties; it is probable that they were not assessed on the more complex constructions. METHODS: Participants were children with or without DD (N = 60) participating in a longitudinal study of development. A summary of the findings comparing those with DS with other groups, on their understanding of syntax is shown in Table 1. The information that you give us will be displayed next to your comment. of the relationship between complex syntax and false-belief-understanding . Documentation of complex syntax development in children with SLI is critical to the clarification of linguistic deficiencies that characterize specific language impairment. Co-ordinated sentences, clausal complements and relative clauses were all noted in the narrative samples, with no significant differences between the groups in either the proportion or the diversity of complex sentences used. The goal of this study was to examine This was in stark contrast to the two control groups, the majority of whom performed above chance level (74%) in the CI group and all of whom performed above chance in the TD group. For the current study, we used a novel method of assessment, designed to minimize non-linguistic demands. Therefore, while our findings suggest that children with DS have significant difficulty understanding complex sentences at this point in their development (with an average mental age of 6;07 years), they may have the potential to understand them as they progress into teenage and adolescent years, with the corresponding increase in their cognitive functioning. We document here how we have responded to each one (with the exception of stylistic/typographical changes, which we have generally incorporated). Performance of children with DS on different clause types. Language development from two to three, New York: Cambridge University, pp. However, Thordartottir and colleagues did highlight the degree of variability in the group with DS. We hypothesised that this may reveal a greater level of syntactic understanding than when using a traditional multiple-choice format. Because this is in effect a two-choice test, it is necessary to give at least eight items per structure to distinguish chance performance from understanding. The current study explored how positive and negative parenting behaviours relate to growth in complex syntax learning from child age 3 to age 4 years, for children with typical development or developmental delays (DDs). In order to compare the two testing methods fairly, we needed to adopt a stringent scoring of the TECS-E, where a pass is credited for perfect performance (8/8 two-choice items correct); the probability of achieving 8/8 by chance (p = 0.004) is the same as for getting all four four-choice items correct on TROG-2. An analysis of Table 6 shows that within each type of complex sentence (relative, adverbial, complement), all three groups performed best on relative clauses, while children’s performance on adverbial and complement clauses was similar within each group. for the sentence If the gate was open the horse could walk away the animation showed that the horse was tied up so that even if the gate was open he could not walk away).

However, in keeping with our hypothesis, verbal short-term memory was strongly predictive of children’s performance on TECS-E. (2017). Therefore, by applying the discontinue rule, if a given number of items are failed, children will not be tested on complex sentences. The test sentences were chosen on the basis of pilot work carried out by the first author, work completed by Diessel & Tomasello (2000); Diessel & Tomasello (2005) and research by Frizelle & Fletcher (2014) and Frizelle et al. If you are a previous or current Wellcome grant holder, sign up for information about developments, publishing and publications from Wellcome Open Research. In sum, given the limited scope of previous research on comprehension, in terms of both methods and linguistic structures, we are uninformed about how individuals with DS process and understand specific complex structures as well as how cognitive ability, memory and hearing level impact the ability of those with DS to deal with these sentence types. 3) Children will have greater difficulty understanding comparable constructions on the multiple-choice test than on the animation task. The finding that intransitive subject relatives were the least difficult to understand (when compared to relatives including a range of syntactic roles) is in keeping with previous research findings in relation to children with DLD (Frizelle & Fletcher, 2014) and children with typical development (Diessel & Tomasello, 2005; Frizelle et al., 2018a). The animations were shown in one of two standard random orders (forward/backward) to control for order effects. Complex syntax thus arises with the need and ability to express complex ideas and information across wide stretches of context. As we highlighted previously, linguistic tests using these multiple-choice tasks are high in executive cognitive demands (Frizelle et al., 2017) and likely to disadvantage those with cognitive impairment of any aetiology (including those with DS, Fragile X, Williams syndrome etc). Based on previous findings (such as those reported by Abbeduto et al., 2003; Chapman, 2006; Laws & Bishop, 2004) we hypothesised that those with DS would perform similarly to those with an intellectual disability of unknown origin but more poorly than the TD group matched on non-verbal ability. Using this approach we found that TD children as young as 3;06 years showed understanding of some complex constructions that they had found difficult when tested using the more traditional multiple choice picture-pointing approach (see Frizelle et al., 2018a). Given that people with DS have a cognitive impairment, we anticipated that these tasks may underestimate their comprehension abilities. The development of complex syntax and mood-selection abilities by . Input-output patterns in the acquisition of Hebrew root usage, Psycholinguistics Research Group: language acquisition and processing. For this reason, we are considering the backward span task to reflect verbal short-term memory rather than working memory. The median effect size from prior literature was 0.19. each relative clause type, complement taking verb and adverbial clause, to avoid tiring children while testing a range of structures. Vocabulary was also cross-referenced with the English MacArthur Bates Communicative Development Inventory (CDI; Fenson et al., 2007) to ensure an early age of acquisition. Complex syntax attempts were coded under the appropriate category for syntactic structure. However, a closer inspection of the data showed that their superior understanding of relative clauses was skewed by their ability to understand one specific relative clause type, intransitive subject relatives, and only one-third of the children with DS showed some understanding of these constructions. After reading articles like this one by Nippold (2017) or this one by Gillon and Dodd (1995) ; I finally started to understand what I may have missed in many cases over the years similar to John’s. Down syndrome (DS) is the most common genetic cause of intellectual disability. We used binomial theorem to establish that a total TECS-E score of 64 or above was significantly different from chance performance at a probability level of 0.01. 2) Binomial Theorem was used to establish a response threshold that was above chance for the TECS-E and TROG assessments. intermediate-level learners of Spanish. Reviewer Expertise: speech, language and communication in children with Williams syndrome, Down syndrome, Reviewer Expertise: Developmental disorders especially those involving communication difficulties. In contrast, the sentence verification task is designed to minimise additional cognitive demands and may therefore be more sensitive to linguistic differences between the groups. Particular thanks are also due to our research assistants Rachel Boland and Anne O’Donoghue. Are sufficient details of methods and analysis provided to allow replication by others? However, it is important to note that most of these studies have used the same assessment measures, with a significant focus on morphology and simple syntax and few embedded sentences. syntactic development of children through counting the MLU (mean length of utterance). (2018a). Email or password not correct. These competing interpretations are presented so that only children with a deep understanding of the construction will chose the correct item. These included versions of the digit recall and backward digit recall subtests from The Working Memory Test Battery for Children (WMTC-C) (Pickering & Gathercole, 2001), adapted for delivery through a laptop. In this study, in keeping with children’s early production of relative clauses (see Diessel, 2004), we focused on relatives that modify the main clause object. In relation to adverbial clauses they performed best on the causal adverbial because and found the conditional adverbial if the most difficult to understand. Using the touch screen the administrator inputted the numbers as the participant recalled them. In this paper we are concerned with complements that serve as the object of the main clause. 1. Syntactic complexity is often taken to be the opposite of coordination: it is mostly associated with non-linearity and degrees of subordination. Accordingly we aimed for a sample of 30 participants per group. It is plausible that the multiple-choice design lowered the performance of each of the cognitively impaired groups participating in these studies, which may have masked any potential differences in the ability of each group to understand a range of sentence structures. If you still need help with your Google account password, please click here. Here we could not make a statistical comparison as children with DS performed at floor on the TROG-2. Based on previous results from 3- to 5-year-old TD children, using this type of task, we hypothesised that children with DS would be able to perform above chance in their understanding of a range of complex sentences.
