Statistical learning ability at 17 months relates to early reading skills via oral language.

Statistical learning ability has been found to relate to children's reading skills. Yet, statistical learning is also known to be vital for developing oral language skills, and oral language and reading skills relate strongly. These connections raise the question of whether statistical learning ability affects reading via oral language or directly. Statistical learning is multifaceted, and so different aspects of statistical learning might influence oral language and reading skills distinctly. In a longitudinal study, we determined how two aspects of statistical learning from an artificial language tested on 70 17-month-old infants-segmenting sequences from speech and generalizing the sequence structure-related to oral language skills measured at 54 months and reading skills measured at approximately 75 months. Statistical learning segmentation did not relate significantly to oral language or reading, whereas statistical learning generalization related to oral language, but only indirectly related to reading. Our results showed that children's early statistical learning ability was associated with learning to read via the children's oral language skills.

Learning to generalise but not segment an artificial language at 17 months predicts children's language skills 3 years later.

We investigated whether learning an artificial language at 17 months was predictive of children's natural language vocabulary and grammar skills at 54 months. Children at 17 months listened to an artificial language containing non-adjacent dependencies, and were then tested on their learning to segment and to generalise the structure of the language. At 54 months, children were then tested on a range of standardised natural language tasks that assessed receptive and expressive vocabulary and grammar. A structural equation model demonstrated that learning the artificial language generalisation at 17 months predicted language abilities - a composite of vocabulary and grammar skills - at 54 months, whereas artificial language segmentation at 17 months did not predict language abilities at this age. Artificial language learning tasks - especially those that probe grammar learning - provide a valuable tool for uncovering the mechanisms driving children's early language development.

The influence of the temporal characteristics of events on adults' and children's pronoun resolution.

We examined the influence of the lexical and grammatical aspect of events on pronoun resolution in adults (18 to 23 years, N = 46), adolescents (13 to 14 years, N=66) and children (7 to 11 years, N=192). Participants were presented with 64 two-sentence stimuli: the first sentence described events with two same gender protagonists; the second began with a personal pronoun and described a status that could be attributed to either protagonist. Participants recorded to whom the pronoun referred, in a booklet. For all groups, Subject resolutions were more likely for events (a) without endpoints relative to those with endpoints, and (b) described as ongoing rather than completed, but this latter influence was restricted to events with endpoints for adults and adolescents. The findings provide support for the Event Structure Hypothesis of pronoun resolution (Rohde, Kehler & Elman, 2006) and provide new insights into the development of pronoun resolution.

The animals in moral tales: Does character realism influence children's prosocial response to stories?

Previous research has suggested that moral stories depicting realistic characters may better facilitate children's prosocial behavior than those containing anthropomorphized animal characters. The current study is a conceptual replication with a different sample and an extended age range. We examined the relationships among story character realism (anthropomorphized animal or human), theme (sharing or busyness), age, and prosocial behavior (i.e., resource allocation). Four versions of an illustrated storybook were created: an Animal Sharing book, an Animal Busy book, a Human Sharing book, and a Human Busy book. A total of 179 children aged 3-7 years listened to one of the four versions of the story. Children's sticker donating behavior was measured prior to hearing the story and again following a story recall task. All groups donated more stickers post-story than pre-story. Younger children were more likely to increase their donation than older children, and children who had made higher human internal state attributions in a previous experimental session donated more stickers post-story. In contrast to previous research, we found that a sharing-themed narrative depicting human characters was no more influential for sticker donation than the other stories.

The Process and Product of Coherence Monitoring in Young Readers: Effects of Reader and Text Characteristics.

We examined sixth graders' detection of inconsistencies in narrative and expository passages, contrasting participants who were monolingual speakers (N = 85) or Spanish-English DLLs (N = 94) when recruited in pre-kindergarten (PK). We recorded self-paced reading times and judgments about whether the text made sense, and took an independent measure of word reading. Main findings were that inconsistency detection was better for narratives, for participants who were monolingual speakers in PK, and for those who were better word readers. When the text processing demands were increased by separating the inconsistent sentence and its premise with filler sentences there was a stronger signal for inconsistency detection during reading for better word readers. Reading patterns differed for texts for which children reported an inconsistency compared to those for which they did not, indicating a failure to adequately monitor for coherence while reading. Our performance measures indicate that narrative and expository texts make different demands on readers.

Assessment of inference-making in children using comprehension questions and story retelling: Effect of text modality and a story presentation format.

BACKGROUND: Reading and listening comprehension are essential for accessing the school curriculum. Inference-making is integral to successful comprehension and involves integrating information between clauses (local coherence) and integrating information with background knowledge (global coherence). We require appropriate methods to assess comprehension and inference-making in order to identify areas of difficulty and provide appropriate support. AIMS: Typically developing children's ability to generate local and global coherence inferences was assessed. The effect of text modality (reading and listening comprehension) and presentation format (stories presented in segmented and whole story format) was explored using two comprehension measures (question answering and story retell). The main aims were to determine whether there were advantages for reading or listening comprehension and for segmented or whole text presentation. METHODS & PROCEDURES: Typically developing children in Year 3 (n = 33) and Year 5 (n = 40) either read or listened to short stories. Their ability to generate global and local coherence inferences was assessed in two ways: answers to inference-tapping questions and story retelling (scored for inclusion of necessary inferences). Stories were presented in either a whole format (all questions after the story) or a segmented format (questions asked at specific points during story presentation); the retelling was always after the complete story and questions had been presented. OUTCOMES & RESULTS: For both comprehension measures, there was developmental progression between age groups and a benefit for the reading modality. Scores were higher for global coherence than local coherence inferences, but the effect was significant only for the question-answering responses, not retells. For retells there was a benefit in presenting the text as a whole compared with the segmented format, but this effect was not present for the comprehension questions. There was a significant interaction between inference type and modality for both comprehension measures (question answering and story retell): for the local coherence inferences scores were significantly greater in the reading compared with the listening modality, but performance on the global coherence inferences did not differ significantly between modalities. CONCLUSIONS & IMPLICATIONS: Clinicians, teachers and other professionals should consider the modality and presentation format for comprehension tasks to utilize areas of strength and support areas of difficulty. Oral presentation may result in poorer comprehension relative to written presentation in general, and may particularly affect local integrative processing. These findings have important implications for the development of appropriate assessments as well as for supporting children with comprehension difficulties. What this paper adds What is already known on the subject Reading and listening comprehension are critical for accessing the school curriculum and educational success. Inference-making is integral to successful comprehension and involves integrating information between clauses (local coherence) as well as integrating information with background knowledge (global coherence). Children have an awareness of the need to generate coherence inferences, but not all children will generate sufficient coherence inferences for adequate comprehension during text presentation. Existing assessment tools measure comprehension by asking questions after story presentation. This provides an overall indication of comprehension or inference-making ability and can identify children with comprehension or language and communication difficulties. What this paper adds to existing knowledge The study compared coherence inference-making in two presentation conditions: whole format (all questions after the story) or segmented format (questions asked at specific points during story presentation). Children (aged 7-10 years) were assessed in the reading or listening modality. Two comprehension measures were used (inference-tapping questions and story retell). There was developmental progression and a benefit for the reading modality for both comprehension measures. Scores were higher for global coherence than local coherence inferences for the comprehension questions. There was a benefit in presenting the text as a whole compared with the segmented format for story retells. What are the potential or actual clinical implications of this work? The results are important for clinicians and other professionals assessing and supporting comprehension skills. The results suggest that the modality and presentation format of comprehension tasks should be considered to utilize areas of strength and support areas of difficulty. The optimum form of input and structure may depend on a child's individual profile and the skill being assessed or supported. Targeted questions may identify a child's potential to generate an inference. This may assist identification of children who may require more targeted or specialist intervention. The reading modality may provide a means of support for development of verbal comprehension.

The role of memory and language ability in children's production of two-clause sentences containing before and after.

We assessed 3- to 6-year-old children's production of two-clause sentences linked by before or after. In two experiments, children viewed an animated sequence of two actions and were asked to describe the order of events in specific target sentence structures. We manipulated whether the target sentence structure matched the chronological order of events (e.g., "He finished his homework, before he played in the garden" [chronological order]) or not (e.g., "Before he played in the garden, he finished his homework" [reverse order]). Children produced fewer accurate target sentences when the presentation order of the two clauses did not match the chronological order of events, specifically for target sentences linked by after. Independent measures of vocabulary and memory both were related to performance, but vocabulary was the stronger predictor. We conclude that developmental improvements in children's ability to produce two-clause sentences linked by a sequential temporal connective are driven primarily by language ability rather than memory capacity per se. This work also highlights the advantages of using both sentence repetition (Experiment 1) and blocked elicited production (Experiment 2) paradigms to elicit sentence production in young children.

Reading comprehension difficulties in children with rolandic epilepsy.

AIM: Difficulties in reading comprehension can arise from either word reading or listening comprehension difficulties, or a combination of the two. We sought to determine whether children with rolandic epilepsy had poor reading comprehension relative to typically developing comparison children, and whether such difficulties were associated with word reading and/or general language comprehension difficulties. METHOD: In this cross-sectional study, children with rolandic epilepsy (n=25; 16 males, 9 females; mean age 9y 1mo, SD 1y 7mo) and a comparison group (n=39; 25 males, 14 females; mean age 9y 1mo, SD 1y 3mo) completed assessments of reading comprehension, listening comprehension, word/non-word reading, speech articulation, and Non-verbal IQ. RESULTS: Reading comprehension and word reading were worse in children with rolandic epilepsy (F1,61 =6.89, p=0.011, ηp2=0.10 and F1,61 =6.84, p=0.011, ηp2=0.10 respectively), with listening comprehension being marginal (F1,61 =3.81, p=0.055, ηp2=0.06). Word reading and listening comprehension made large and independent contributions to reading comprehension, explaining 70% of the variance. INTERPRETATION: Children with rolandic epilepsy may be at risk of reading comprehension difficulties. Thorough assessment of individual children is required to ascertain whether the difficulties lie with decoding text, or with general comprehension skills, or both. WHAT THIS PAPER ADDS: Children with rolandic epilepsy may be at risk of poor reading comprehension. This was related to poor word reading, poor listening comprehension, or both. Reading comprehension interventions should be tailored to the profile of difficulties.

Assessing school-aged children's inference-making: the effect of story test format in listening comprehension.

BACKGROUND: Comprehension is critical for classroom learning and educational success. Inferences are integral to good comprehension: successful comprehension requires the listener to generate local coherence inferences, which involve integrating information between clauses, and global coherence inferences, which involve integrating textual information with background knowledge to infer motivations, themes, etc. A central priority for the diagnosis of comprehension difficulties and our understanding of why these difficulties arise is the development of valid assessment instruments. AIMS: We explored typically developing children's ability to make local and global coherence inferences using a novel assessment of listening comprehension. The aims were to determine whether children were more likely to make the target inferences when these were asked during story presentation versus after presentation of the story, and whether there were any age differences between conditions. METHODS & PROCEDURES: Children in Years 3 (n = 29) and 5 (n = 31) listened to short stories presented either in a segmented format, in which questions to assess local and global coherence inferences were asked at specific points during story presentation, or in a whole format, when all the questions were asked after the story had been presented. OUTCOMES & RESULTS: There was developmental progression between age groups for both types of inference question. Children also scored higher on the global coherence inference questions than the local coherence inference questions. There was a benefit of the segmented format for younger children, particularly for the local inference questions. CONCLUSIONS & IMPLICATIONS: The results suggest that children are more likely to make target inferences if prompted during presentation of the story, and that this format is particularly facilitative for younger children and for local coherence inferences. This has implications for the design of comprehension assessments as well as for supporting children with comprehension difficulties in the classroom.

Lexical prosody beyond first-language boundary: Chinese lexical tone sensitivity predicts English reading comprehension.

This 1-year longitudinal study examined the role of Cantonese lexical tone sensitivity in predicting English reading comprehension and the pathways underlying their relation. Multiple measures of Cantonese lexical tone sensitivity, English lexical stress sensitivity, Cantonese segmental phonological awareness, general auditory sensitivity, English word reading, and English reading comprehension were administered to 133 Cantonese-English unbalanced bilingual second graders. Structural equation modeling analysis identified transfer of Cantonese lexical tone sensitivity to English reading comprehension. This transfer was realized through a direct pathway via English stress sensitivity and also an indirect pathway via English word reading. These results suggest that prosodic sensitivity is an important factor influencing English reading comprehension and that it needs to be incorporated into theoretical accounts of reading comprehension across languages.

Young Children's Comprehension of Temporal Relations in Complex Sentences: The Influence of Memory on Performance.

The present study investigated 3- to 7-year-olds' (N = 91) comprehension of two-clause sentences containing the temporal connectives before or after. The youngest children used an order of mention strategy to interpret the relation between clauses: They were more accurate when the presentation order matched the chronological order of events: "He ate his lunch, before he played in the garden" (chronological) versus "Before he played in the garden, he ate his lunch" (reverse). Between 4 and 6 years, performance was influenced by a combination of factors that influenced processing load: connective type and presentation order. An independent measure of working memory was predictive of performance. The study concludes that the memory demands of some sentence structures limits young children's comprehension of sentences containing temporal connectives.

Children's inference generation: The role of vocabulary and working memory.

Inferences are crucial to successful discourse comprehension. We assessed the contributions of vocabulary and working memory to inference making in children aged 5 and 6years (n=44), 7 and 8years (n=43), and 9 and 10years (n=43). Children listened to short narratives and answered questions to assess local and global coherence inferences after each one. Analysis of variance (ANOVA) confirmed developmental improvements on both types of inference. Although standardized measures of both vocabulary and working memory were correlated with inference making, multiple regression analyses determined that vocabulary was the key predictor. For local coherence inferences, only vocabulary predicted unique variance for the 6- and 8-year-olds; in contrast, none of the variables predicted performance for the 10-year-olds. For global coherence inferences, vocabulary was the only unique predictor for each age group. Mediation analysis confirmed that although working memory was associated with the ability to generate local and global coherence inferences in 6- to 10-year-olds, the effect was mediated by vocabulary. We conclude that vocabulary knowledge supports inference making in two ways: through knowledge of word meanings required to generate inferences and through its contribution to memory processes.

Inferential revision in narrative texts: An ERP study.

We evaluated the process of inferential revision during text comprehension in adults. Participants with high or low working memory read short texts, in which the introduction supported two plausible concepts (e.g., 'guitar/violin'), although one was more probable ('guitar'). There were three possible continuations: a neutral sentence, which did not refer back to either concept; a no-revise sentence, which referred to a general property consistent with either concept (e.g., '…beautiful curved body'); and a revise sentence, which referred to a property that was consistent with only the less likely concept (e.g., '…matching bow'). Readers took longer to read the sentence in the revise condition, indicating that they were able to evaluate their comprehension and detect a mismatch. In a final sentence, a target noun referred to the alternative concept supported in the revise condition (e.g., 'violin'). ERPs indicated that both working memory groups were able to evaluate their comprehension of the text (P3a), but only high working memory readers were able to revise their initial incorrect interpretation (P3b) and integrate the new information (N400) when reading the revise sentence. Low working memory readers had difficulties inhibiting the no-longer-relevant interpretation and thus failed to revise their situation model, and they experienced problems integrating semantically related information into an accurate memory representation.

Reading and listening comprehension and their relation to inattention and hyperactivity.

BACKGROUND: Children with diagnoses of attention-deficit/hyperactivity disorder (ADHD) frequently have reading problems. To date, it is not clear whether poor reading is associated with both inattention and hyperactivity and also whether poor reading comprehension is the result of poor word reading skills or more general language comprehension weaknesses. AIMS: We report two studies to examine how reading and listening comprehension skills are related to inattention and hyperactivity/impulsivity. SAMPLES: Separate groups of 7- to 11-year-olds participated in each study. METHODS: In both studies, we used teacher ratings of inattention and hyperactivity/impulsivity to identify three groups at risk of ADHD: poor attention, high hyperactivity, poor attention and high hyperactivity, and also same-age controls. In Study 1, we explored how inattention and hyperactivity predicted reading after controlling for non-verbal IQ and vocabulary. In Study 2, we compared listening and reading comprehension in these groups. RESULTS: Poor attention was related to poor reading comprehension, although the relation was partially mediated by word reading skill (Study 1). Groups with high hyperactivity had weak listening comprehension relative to reading comprehension (Study 2). CONCLUSIONS: These results indicate that the reading comprehension problems of children with attention difficulties are related to poor word reading and that listening comprehension is particularly vulnerable in children at risk of ADHD.

Text integration processes in children with Childhood Epilepsy with Centro-Temporal Spikes.

Although Childhood Epilepsy with Centro-Temporal Spikes (CECTS) is considered a 'benign' form of epilepsy, word reading, listening comprehension, and reading comprehension difficulties have been reported. We examined two core skills for text comprehension, coherence monitoring and inference generation, in children with CECTS and compared performance with typically developing controls. Children with CECTS (n = 23; 9 females; mean age 9 y 0 m) and the comparison group (n = 38; 14 females; mean age 9 y 1 m) completed two tasks. For coherence monitoring they heard 24 narrative texts, 16 containing two inconsistent sentences, and responded to a yes/no question to assess identification of the inconsistency after each text; for inference making they heard 16 texts designed to elicit a target inference by integrating information in two sentences and responded to a yes/no question to assess generation of the inference. In both tasks there was a near condition, in which critical sentences were adjacent, and a far condition in which these sentences were separated by filler sentences. Accuracy to the question and the processing time for critical sentences in the text were measured. We used listening comprehension tasks to control for variation in word reading ability. Mixed effects analyses for each task revealed that children with CECTS show comparable levels of accuracy to age-matched peers in these tasks tapping two core text integration skills: detection of inconsistencies and generation of inferences. However, they take longer to process texts indicating a likely source of their listening and reading comprehension difficulties.

Reading for Comprehension in Individuals with Down Syndrome, Autism Spectrum Disorder and Typical Development: Similar or Different Patterns of Ability?

Reading for meaning is one of the most important activities in school and everyday life. The simple view of reading (SVR) has been used as a framework for studies of reading comprehension in individuals with Down syndrome (DS). These tend to show difficulties in reading comprehension despite better developed reading accuracy. Reading comprehension difficulties are influenced by poor oral language. These difficulties are common in individuals with DS and autism spectrum disorder (ASD), but they have never been compared directly. Moreover, the components of reading for comprehension have rarely been investigated in these populations: a better understanding of the nature of reading comprehension difficulties may inform both theory and practice. The aim of this study was to determine whether reading comprehension in the two populations is accounted for by the same component skills and to what extent the reading profile of the two atypical groups differs from that of typically developing children (TD). Fifteen individuals with DS (mean age = 22 years 4 months, SD = 5 years 2 months), 21 with ASD (mean age = 13 years 2 months, SD = 1 year 6 months), and 42 TD children (mean age = 8 years 1 month, SD = 7 months) participated and were assessed on measures of receptive vocabulary, text reading and listening comprehension, oral language comprehension, and reading accuracy. The results showed similar levels in word reading accuracy and in receptive vocabulary in all three groups. By contrast, individuals with DS and ASD showed poorer non-word reading and reading accuracy in context than TD children. Both atypical groups showed poorer listening and reading text comprehension compared to TD children. Reading for comprehension, investigated through a homograph reading accuracy task, showed a different pattern for individuals with DS with respect to the other two groups: they were less sensitive to meaning while reading. According to the SVR, the current results confirm that the two atypical groups have similar profiles that overlap with that of poor comprehenders in which poor oral language comprehension constrains reading for comprehension.

Going beyond children's single-text comprehension: The role of fundamental and higher-level skills in 4th graders' multiple-document comprehension.

BACKGROUND: Children's comprehension of single texts relies on both foundational and higher-level skills. These are also assumed to support multiple-document comprehension, but their relative importance has not been examined, to date. Multiple-document comprehension additionally requires the identification and use of information about each document's source. AIMS: This study examined multiple-document comprehension in primary school-aged children. It sought to determine the relative importance of skills proposed to be common to both single-text and multiple-document comprehension (word reading fluency, verbal working memory, comprehension monitoring) and specific to the latter (source use). Single-text comprehension and prior topic knowledge were considered as moderator and control. SAMPLE: Participants were 94 children in the fourth year (mean age = 9; 7 years; 52% females). METHODS: Children read three documents on each of two topics (chocolate and video games). Multiple-document comprehension and source use were assessed through short essays. Independent measures of the fundamental and higher-level skills were used. RESULTS: There was a significant direct and indirect influence of word reading fluency on comprehension of multiple documents on videogames and also an indirect influence of comprehension monitoring. Indirect influences of word reading fluency and comprehension monitoring on multiple-document comprehension for both topics were also apparent. Verbal working memory was not a unique predictor. When source information was identified, it was included to support the argument in the composition. CONCLUSIONS: Efficient word reading, comprehension monitoring, and single-text comprehension are important for multiple-document comprehension in young readers. Implications of these findings and differences between the two document sets are discussed.

Narrative comprehension and engagement with e-books vs. paper-books in autism spectrum condition.

Background and aims: Children with autism spectrum condition often have specific difficulties with narrative comprehension, a skill which has a strong association with both concurrent and longitudinal reading comprehension. A better understanding of narrative comprehension skills in autism spectrum condition has the potential to provide insight into potential later reading comprehension difficulties and inform early targeted intervention. In the current study, the main objective was to investigate how differences in the medium of story presentation (paper-book vs. e-book) and differences in story narration (adult narration vs. in-app narration) would influence narrative comprehension in general, and between groups (autism spectrum condition and a receptive language-matched control group). We were also interested in how task engagement (visual attention and communication) differed between group and conditions and whether task engagement was related to narrative comprehension. Method: Forty-two children with autism spectrum condition and 42 typically developing children were read a story either via a paper-book or an e-book with interactive and multimedia features. The e-book was either narrated by the experimenter (adult narrated iPad condition) or narrated by an in-app voiceover (e-book narrated iPad condition). Children's behaviour during storybook reading was video recorded and coded for engagement (visual attention and communication). They then completed two measures of narrative comprehension: multiple-choice questions (measuring recall of literal information) and a picture ordering task (measuring global story structure). Results: Contrary to predictions, we did not find any significant group or condition differences on either measure of narrative comprehension, and both groups demonstrated a similar level of narrative comprehension across the three conditions. We found differences in engagement between conditions for both groups, with greater visual attention in the e-book conditions compared to the paper-book condition. However, visual attention only significantly correlated with narrative comprehension for the typically developing group. Conclusion: Overall, this study suggests that children with autism spectrum condition are just as able as language-matched peers to comprehend a narrative from storybooks. Presenting a story on an iPad e-book compared to a paper-book does not influence narrative comprehension, nor does adult narration of the story compared to in-app narration. However, on-task engagement is linked to narrative comprehension in typically developing children.Implications: Taken together, our findings suggest that e-books may be more successful than paper-based mediums at encouraging visual attention towards the story, but no better at supporting narrative comprehension and eliciting communication.

The influence of labelling on symbolic understanding and dual representation in autism spectrum condition.

Background and aims: Children with autism spectrum condition often have specific difficulties understanding that pictorial symbols refer to real-world objects in the environment. We investigated the influence of labelling on the symbolic understanding and dual representation of children with autism spectrum condition. Methods: Children with autism spectrum condition and typically developing children were shown four coloured photographs of objects that had different functions across four separate trials. The participants were given either a novel label alongside a description of the object's function or a description of the object's function without a label. Children were then given 30 seconds to interact with an array of stimuli (pictures and objects) in a mapping test and in a generalisation test for each trial. This exploration phase allowed for spontaneous word-picture-referent mapping through free-play, providing an implicit measure of symbolic understanding. Results: We found no significant difference in word-picture-referent mapping between groups and conditions. Both groups more often performed the described action on the target object in the exploration phase regardless of condition. Conclusions and implications: Our results suggest that a spontaneous measure of symbolic understanding (such as free-play) may reveal competencies in word-picture-referent mapping in autism spectrum condition.

Symbolic Understanding and Word-Picture-Referent Mapping from iPads in Autism Spectrum Condition: The Roles of Iconicity and Engagement.

We investigated symbolic understanding, word-picture-referent mapping, and engagement in children with autism spectrum condition (ASC) and ability-matched typically developing children. Participants viewed coloured pictorial symbols of a novel object (given a novel name) on an iPad in one of three conditions: static 2D images and either automatically or manually rotating images (providing a three-dimensional context). We found no significant difference in word-picture-referent mapping between groups and conditions, however, children who manually rotated the picture had greater on-screen looking time compared to other conditions. Greater visual attention related to more successful word-picture-referent mapping only for the children with ASC. Interactive iPad tasks may increase visual attention in both typical and atypical populations and greater visual attention may benefit word-picture-referent mapping in ASC.
