How does caregiver-child conversation during a scientific storybook reading impact children's mindset beliefs and persistence?

This study explores how caregiver-child scientific conversation during storybook reading focusing on the challenges or achievements of famous female scientists impacts preschoolers' mindset, beliefs about success, and persistence. Caregiver-child dyads (N = 202, 100 female, 35% non-White, aged 4-5, ƒ = .15) were assigned to one of three storybook conditions, highlighting the female scientist's achievements, effort, or, in a baseline condition, neither. Children were asked about their mindset, presented with a persistence task, and asked about their understanding of effort and success. Findings demonstrate that storybooks highlighting effort are associated with growth mindset, attribution of success to hard work, and increased persistence. Caregiver language echoed language from the assigned storybook, showing the importance of reading storybooks emphasizing hard work.

What would happen if?: A comparison of fathers' and mothers' questions to children during a science activity.

Parents' questions are an effective strategy for fostering the development of young children's science understanding and discourse. However, this work has not yet distinguished whether the frequency of questions about scientific content differs between mothers and fathers, despite some evidence from other contexts (i.e., book reading) showing that fathers ask more questions than mothers. The current study compared fathers' and mothers' questions to their four- to six-year-old children (N = 49) while interacting with scientific stimuli at a museum research exhibit. Results indicated that fathers asked significantly more questions than mothers, and fathers' questions were more strongly related to children's scientific discourse. Results are discussed in terms of the importance of adult questions for the development of children's scientific understanding as well as broadening research to include interlocutors other than mothers.

Positive impacts of a strengths-based family program on Latino kindergarteners' narrative language abilities.

Narrative language abilities are foundational to literacy development and are a culturally grounded measure of early literacy for Latino children. This study evaluates the impacts on narrative language abilities and the costs of a 4-week, strengths-based program that leverages two valued sociocultural practices with built-in benefits, personal narratives, and family food routines (e.g., grocery shopping), for improving Latino kindergarteners' learning outcomes in the United States. Two-hundred and 34 children (M age = 67 months; 51% girls; 13 schools) and their parents participated in a cluster randomized trial. Children produced personal narratives at three time points: pretest, end-of-treatment, and 5-month follow-up. Four narrative features were measured: narrative coherence, elaborations, word types, and literate language features. Large positive impacts were observed on all four narrative features at the end-of-treatment posttest (d = 1.21-1.76). There was suggestive evidence of moderate impacts on one narrative feature (i.e., narrative coherence) at the 5-month follow-up (d = .59). The costs required to implement the family program were relatively low. Findings highlight the potential value of implementing this strengths-based program in schools serving Latino kindergarteners using a rigorous evaluation of its effectiveness.

An intervention to increase conversational turns between parents and young children.

Behavioral and neural evidence indicates that young children who engage in more conversations with their parents have better later language skills such as vocabulary and academic language abilities. Previous studies find that the extent to which parents engage in conversational turn-taking with children varies considerably. How, then, can we promote extended conversations between parents and their children? Instead of asking parents to engage in longer turn-taking episodes, we provided parents with information on conversational content that we hypothesized would lead to increased episodes of longer, more sustained conversational turn-taking. Specifically, we found that boosting the frequency of parent-child talk about abstract, non-present concepts - decontextualized language - led to an increase in dyadic conversational turn-taking during home mealtimes several weeks later.

Investigating Science Together: Inquiry-Based Training Promotes Scientific Conversations in Parent-Child Interactions.

This study examined the effects of two pedagogical training approaches on parent-child dyads' discussion of scientific content in an informal museum setting. Forty-seven children (mean age = 5.43) and their parents were randomly assigned to training conditions where an experimenter modeled one of two different pedagogical approaches when interacting with the child and a science-based activity: (1) a scientific inquiry-based process or (2) a scientific statement-sharing method. Both approaches provided the same information about scientific mechanisms but differed in the process through which that content was delivered. Immediately following the training, parents were invited to model the same approach with their child with a novel science-based activity. Results indicated significant differences in the process through which parents prompted discussion of the targeted information content: when talking about causal scientific concepts, parents in the scientific inquiry condition were significantly more likely to pose questions to their child than parents in the scientific statements condition. Moreover, children in the scientific inquiry condition were marginally more responsive to parental causal talk and provided significantly more scientific content in response. These findings provide initial evidence that training parents to guide their children using scientific inquiry-based approaches in informal learning settings can encourage children to participate in more joint scientific conversations.

Embedding Scientific Explanations Into Storybooks Impacts Children's Scientific Discourse and Learning.

Children's understanding of unobservable scientific entities largely depends on testimony from others, especially through parental explanations that highlight the mechanism underlying a scientific entity. Mechanistic explanations are particularly helpful in promoting children's conceptual understanding, yet they are relatively rare in parent-child conversations. The current study aimed to increase parent-child use of mechanistic conversation by modeling this language in a storybook about the mechanism of electrical circuits. We also examined whether an increase in mechanistic conversation was associated with science learning outcomes, measured at both the dyadic- and child-level. In the current study, parents and their 4- to 5-year-old children (N = 60) were randomly assigned to read a book containing mechanistic explanations (n = 32) or one containing non-mechanistic explanations (n = 28). After reading the book together, parent-child joint understanding of electricity's mechanism was tested by asking the dyad to assemble electrical components of a circuit toy so that a light would turn on. Finally, child science learning outcomes were examined by asking children to assemble a novel circuit toy and answer comprehension questions to gauge their understanding of electricity's mechanism. Results indicate that dyads who read storybooks containing mechanistic explanations were (1) more successful at completing the circuit (putting the pieces together to make the light turn on) and (2) used more mechanistic language than dyads assigned to the non-mechanistic condition. Children in the mechanistic condition also had better learning outcomes, but only if they engaged in more mechanistic discourse with their parent. We discuss these results using a social interactionist framework to highlight the role of input and interaction for learning. We also highlight how these results implicate everyday routines such as book reading in supporting children's scientific discourse and understanding.

Conflicting perspectives mediate the relation between parents' and preschoolers' self-referent mental state talk during collaboration.

We examined the relations between the referent of parents and preschoolers' mental state talk during a collaborative puzzle-solving task (N = 146 dyads; n = 81 3-year-olds, n = 65 4-year-olds). The results showed that parents' references to their own knowledge and beliefs (self-referent cognitive talk), and references to their child's knowledge and beliefs (child-referent cognitive talk) were both related to children's (primarily self-referent) cognitive talk. We then tested whether any of the observed relations could be explained by the presence of conflicting perspectives within the collaborative interaction. Mediational analyses revealed that conflicting perspectives mediated the positive relation between parents' production of self-referent cognitive talk and child cognitive talk. By contrast, the positive relation between parents' production of child-referent cognitive talk and child cognitive talk did not depend on the presence of this type of conflict. These findings highlight an important mechanism through which parents' references to their own mind might promote children's developing mental state talk in collaborative contexts.

Language Growth Predicts Stuttering Persistence Over and Above Family History and Treatment Experience: Response to Marcotte.

Purpose This response addresses comments made by Marcotte (2019) regarding our recent publication, "Preliminary Evidence That Growth in Productive Language Differentiates Childhood Stuttering Persistence and Recovery" ( Leech, Bernstein Ratner, Brown, & Weber, 2017 ). Marcotte calls into question our finding that language growth is a valid predictor of recovery from stuttering because we did not account for treatment and family history. Conclusions In response to her comments, we provide additional empirical analyses couched in a larger discussion of the difficulty of calibrating treatment and family history of stuttering. In short, we show that once treatment history and family history of stuttering are accounted for, the effect of language growth remains a significant predictor of stuttering persistence.

On the malleability of selective trust.

Although much research has explored the cues that young children use to determine informant credibility, little research has examined whether credibility judgments can change over time as a function of children's language environment. This study explored whether changes in the syntactic complexity of adults' testimony shifts 4- and 5-year-old children's (N = 42) credibility and learning judgments. Children from lower-socioeconomic status (SES) backgrounds were randomly assigned to hear a high proportion of complex language (the passive voice) or simpler language (the active voice) during 10 days of book-reading interactions with adult experimenters. Before and after the book-reading sessions, children's learning preferences for informants who used passive versus active voice were measured. Exposure to the complex passive voice led children to use syntactic complexity as a cue to make inferences about who to learn from, whereas active voice exposure resulted in no such shift. Implications for the role of the language environment in children's selective trust are discussed.

Conversation about the future self improves preschoolers' prospection abilities.

Prospection, the ability to engage in future-oriented thinking and decision making, begins to develop during the preschool years yet remains far from adult-like. One specific challenge for children of this age is with regard to thinking and reasoning about their future selves. Drawing from work indicating the importance of adult-child conversation in language and cognitive development, the current study examined the extent to which conversations about the future and the self may facilitate preschool-aged children's prospective thinking. The participants, 4- and 5-year-old children (N = 68), were randomly assigned to read books surrounding one of four topics with an adult experimenter: their present self, their future self, another child's present self, or another child's future self. Children whose conversations were centered on their future selves outperformed other children in the sample on a battery of prospection assessments taken immediately after the manipulation. Of the three prospection assessments administered, the manipulation had the strongest effect on children's prospective memories. Results are discussed in terms of the role that everyday conversation can play in fostering children's cognitive development during the early childhood years.

A parent intervention with a growth mindset approach improves children's early gesture and vocabulary development.

Socioeconomic disparities in children's early vocabulary skills can be traced back to disparities in gesture use at age one and are due, in part, to the quantity and quality of communication children are exposed to by parents. Further, parents' mindsets about intelligence contribute to their interactions with their children. We implemented a parent gesture intervention with a growth mindset component with 47 parents of 10-month-olds to determine whether this approach would increase parents' use of the pointing gesture, infants' use of pointing, and child vocabulary growth. The intervention had an effect on parent gesture such that by child age 12-months, parents who received the intervention increased in their pointing more than parents in the control condition. Importantly, the intervention also had a significant effect on child gesture use with parents. There was no main effect of the intervention on child vocabulary. Further, the effect of the intervention on pointing was stronger for parents who endorsed fixed mindsets at baseline, and had an added benefit of increased vocabulary growth from 10-18 months for children of those parents who endorsed fixed mindsets. Incorporating growth mindset approaches into parenting interventions is encouraged.

Development of fine motor skills is associated with expressive language outcomes in infants at high and low risk for autism spectrum disorder.

BACKGROUND: A growing body of research suggests that fine motor abilities are associated with skills in a variety of domains in both typical and atypical development. In this study, we investigated developmental trajectories of fine motor skills between 6 and 24 months in relation to expressive language outcomes at 36 months in infants at high and low familial risk for autism spectrum disorder (ASD). METHODS: Participants included 71 high-risk infants without ASD diagnoses, 30 high-risk infants later diagnosed with ASD, and 69 low-risk infants without ASD diagnoses. As part of a prospective, longitudinal study, fine motor skills were assessed at 6, 12, 18, and 24 months of age and expressive language outcomes at 36 months using the Mullen Scales of Early Learning. Diagnosis of ASD was determined at the infant's last visit to the lab (18, 24, or 36 months) using the Autism Diagnostic Observation Schedule. RESULTS: Hierarchical linear modeling revealed that high-risk infants who later developed ASD showed significantly slower growth in fine motor skills between 6 and 24 months, compared to their typically developing peers. In contrast to group differences in growth from age 6 months, cross-sectional group differences emerged only in the second year of life. Also, fine motor skills at 6 months predicted expressive language outcomes at 3 years of age. CONCLUSIONS: These results highlight the importance of utilizing longitudinal approaches in measuring early fine motor skills to reveal subtle group differences in infancy between ASD high-risk and low-risk infant populations and to predict their subsequent language outcomes.

A brief parent-focused intervention to improve preschoolers' conversational skills and school readiness.

Preschool children's use of decontextualized language, or talk about abstract topics beyond the here-and-now, is predictive of their kindergarten readiness and is associated with the frequency of parents' own use of decontextualized language. Does a brief, parent-focused intervention conveying the importance of decontextualized language cause parents to increase their use of these conversations, and as a result, their children's? We examined this question by randomly assigning 36 parents of 4-year-old children into a decontextualized language training condition or a no-treatment control condition and used mixed effects modeling to measure change (from baseline) in parent and child decontextualized language at 4 subsequent home mealtimes during the following month (N = 174 interactions including the baseline). Compared with the control condition, training condition dyads significantly increased their decontextualized talk and maintained these gains for the month following implementation. Furthermore, trained dyads generalized the program content to increase their use of similarly decontextualized, yet untrained conversations. These results demonstrate that an abstract feature of the input is malleable, and introduces a simple, scalable, and replicable approach to increase a feature of child language known to be foundational for children's school readiness.

Preliminary Evidence That Growth in Productive Language Differentiates Childhood Stuttering Persistence and Recovery.

Purpose: Childhood stuttering is common but is often outgrown. Children whose stuttering persists experience significant life impacts, calling for a better understanding of what factors may underlie eventual recovery. In previous research, language ability has been shown to differentiate children who stutter (CWS) from children who do not stutter, yet there is an active debate in the field regarding what, if any, language measures may mark eventual recovery versus persistence. In this study, we examined whether growth in productive language performance may better predict the probability of recovery compared to static profiles taken from a single time point. Method: Productive syntax and vocabulary diversity growth rates were calculated for 50 CWS using random coefficient models. Logistic regression models were then used to determine whether growth rates uniquely predict likelihood of recovery, as well as if these rates were predictive over and above currently identified correlates of stuttering onset and recovery. Results: Different linguistic profiles emerged between children who went on to recover versus those who persisted. Children who had steeper productive syntactic growth, but not vocabulary diversity growth, were more likely to recover by study end. Moreover, this effect held after controlling for initial language ability at study onset as well as demographic covariates. Conclusions: Results are discussed in terms of how growth estimates can be incorporated in recommendations for fostering productive language skills among CWS. The need for additional research on language in early stuttering and recovery is suggested.

Training preschoolers' prospective abilities through conversation about the extended self.

The ability to act on behalf of one's future self is related to uniquely human abilities such as planning, delay of gratification, and goal attainment. Although prospection develops rapidly during early childhood, little is known about the mechanisms that support its development. Here we explored whether encouraging children to talk about their extended selves (self outside the present context) boosts their prospective abilities. Preschoolers (N = 81) participated in a 5-min interaction with an adult in which they were asked to talk about events in the near future, distant future, near past, or present. Compared with children discussing their present and distant future, children asked to discuss events in their near future or near past displayed better planning and prospective memory. Additionally, those 2 conditions were most effective in eliciting self-projection (use of personal pronouns). Results suggest that experience communicating about the temporally contiguous, extended self may promote children's future-oriented thinking. (PsycINFO Database Record

Going Beyond Input Quantity: Wh-Questions Matter for Toddlers' Language and Cognitive Development.

There are clear associations between the overall quantity of input children are exposed to and their vocabulary acquisition. However, by uncovering specific features of the input that matter, we can better understand the mechanisms involved in vocabulary learning. We examine whether exposure to wh-questions, a challenging quality of the communicative input, is associated with toddlers' vocabulary and later verbal reasoning skills in a sample of low-income, African-American fathers and their 24-month-old children (n = 41). Dyads were videotaped in free play sessions at home. Videotapes were transcribed and reliably coded for sheer quantity of fathers' input (number of utterances) as well as the number of wh-questions fathers produce. Children's productive vocabulary was measured at 24 months using the McArthur Bates Communicative Development Inventory MCDI (completed by the mothers), and children's verbal reasoning skills were measured 1 year later using the Bayley Scales of Infant Development. Results indicate that the overall quantity of father talk did not relate to children's vocabulary or reasoning skills. However, fathers' use of wh-questions (but not other questions) related to both vocabulary and reasoning outcomes. Children's responses to wh-questions were more frequent and more syntactically complex, measured using the mean length of utterance (MLU), than their responses to other questions. Thus, posing wh-questions to 2-year-olds is a challenging type of input, which elicits a verbal response from the child that likely helps build vocabulary and foster verbal reasoning abilities.

Exploring socioeconomic differences in syntactic development through the lens of real-time processing.

Differences in caregiver input across socioeconomic status (SES) predict syntactic development, but the mechanisms are not well understood. Input effects may reflect the exposure needed to acquire syntactic representations during learning (e.g., does the child have the relevant structures for passive sentences?) or access this knowledge during communication (e.g., can she use the past participle to infer the meaning of passives?). Using an eye-tracking and act-out paradigm, the current study distinguishes these mechanisms by comparing the interpretation of actives and passives in 3- to 7-year-olds (n=129) from varying SES backgrounds. During the presentation of spoken sentences, fixations revealed robust disambiguation of constructions by children from higher-SES backgrounds, but less sensitivity by lower-SES counterparts. After sentence presentation, decreased sensitivity generated interpretive challenges and average SES-related differences for passives requiring syntactic revision ("The seal is quickly eaten by it"). Critically, no differences were found when revision was not needed ("It is quickly eaten by the seal"). These results suggest that all children shared an ability to acquire passives, but SES-related differences in real-time processing can impact the accuracy of utterance interpretation.

Variations in the recruitment of syntactic knowledge contribute to SES differences in syntactic development.

Average differences in children's language abilities by socioeconomic status (SES) emerge early in development and predict academic achievement. Previous research has focused on coarse-grained outcome measures such as vocabulary size, but less is known about the extent to which SES differences exist in children's strategies for comprehension and learning. We measured children's (N = 98) comprehension of passive sentences to investigate whether SES differences are more pronounced in overall knowledge of the construction or in more specific abilities to process sentences during real-time interpretation. SES differences in comprehension emerged when syntactic revision of passives was necessary, and disappeared when the need to revise was removed. Further, syntactic revision but not knowledge of the passive best explained the association between SES and a standardized measure of syntactic development. These results demonstrate that SES differences in syntactic development may result from how children recruit syntactic information within sentences.

Low-income fathers' speech to toddlers during book reading versus toy play.

Fathers' child-directed speech across two contexts was examined. Father-child dyads from sixty-nine low-income families were videotaped interacting during book reading and toy play when children were 2;0. Fathers used more diverse vocabulary and asked more questions during book reading while their mean length of utterance was longer during toy play. Variation in these specific characteristics of fathers' speech that differed across contexts was also positively associated with child vocabulary skill measured on the MacArthur-Bates Communicative Development Inventory. Results are discussed in terms of how different contexts elicit specific qualities of child-directed speech that may promote language use and development.
