Something About the Way You Speak: A Meta-analysis on Children’s Linguistic-based Social Preferences

There is growing interest in the role of linguistic cues (accents, dialects, language) in driving children’s social preferences. This meta-analysis integrated 131 effect sizes involving 2,680 infants and children from 2 days old to 11 years. Overall, children prefer native-accent, native-dialect, and native-language speakers over non-native counterparts (d = 0.57). Meta-regression highlighted that bilinguals (d = 0.93) do not exhibit less native-speaker preference compared to monolinguals (d = 0.62). Children displayed stronger preferences based on accent (d = 1.04) than dialect (d = 0.44) and language (d = 0.39). Children’s cultural background, exposure to non-native speech, age, and preference measure were not significant moderators. The data are discussed in light of several theoretical explanations for when and why children show linguistic-based social preferences.     

Children’s Intergroup Attitudes: Insights From Iran

Children generally favor individuals in their own group over others, but it is unclear which dimensions of the out-group affect this bias. This issue was investigated among 7- to 8-year-old and 11- to 12-year-old Iranian children (N = 71). Participants evaluated in-group members and three different out-groups: Iranian children from another school, Arab children, and children from the United States. Children’s evaluations closely aligned with the perceived social status of the groups, with Americans viewed as positively as in-group members and Arabs viewed negatively. These patterns were evident on measures of affiliation, trust, and loyalty. These findings, which provide some of the first insights into the social cognition of Iranian children, point to the role of social status in the formation of intergroup attitudes.     

Preserving the Past: An Early Interview Improves Delayed Event Memory in Children With Intellectual Disabilities

The influence of an early interview on children's (N = 194) later recall of an experienced event was examined in children with mild and moderate intellectual disabilities (CWID; 7–12 years) and typically developing (TD) children matched for chronological (7–12 years) or mental (4–9 years) age. Children previously interviewed were more informative, more accurate, and less suggestible. CWID (mild) recalled as much information as TD mental age matches, and were as accurate as TD chronological age matches. CWID (moderate) recalled less than TD mental age matches but were as accurate. Interviewers should elicit CWID's recall as early as possible and consider developmental level and severity of impairments when evaluating eyewitness testimony.     

Longitudinal Trajectories of Four Domains of Parenting in Relation to Adolescent Age and Puberty in Nine Countries

Children, mothers, and fathers in 12 ethnic and regional groups in nine countries (N = 1,338 families) were interviewed annually for 8 years (M_age child = 8–16 years) to model four domains of parenting as a function of child age, puberty, or both. Latent growth curve models revealed that for boys and girls, parents decrease their warmth, behavioral control, rules/limit-setting, and knowledge solicitation in conjunction with children’s age and pubertal status as children develop from ages 8 to 16 across a range of diverse contexts, with steeper declines after age 11 or 12 in three of the four parenting domains. National, ethnic, and regional differences and similarities in the trajectories as a function of age and puberty are discussed.     

Do Varieties of Spanish Influence U.S. Spanish–English Bilingual Children's Friendship Judgments?

Latinos are the largest minority group in the United States (U.S. Census, 2014), yet this term comprises individuals from multiple ethnicities who speak distinct varieties of Spanish. We investigated whether Spanish–English bilingual children (N = 140, ages 4–17) use Spanish varieties in their social judgments. The findings revealed that children distinguished varieties of Spanish but did not use Spanish dialects to make third-person friendship judgments until 10–12 years; this effect became stronger in adolescence. In contrast, young children (4–6 years) made friendship judgments based on a speaker's language (English, Spanish). Thus, using language varieties as a social category and as a basis for making social inferences is a complex result of multiple influences for Spanish-speaking children growing up bilingual in the United States.     

Developmental Trends in Flexibility and Automaticity of Social Cognition

Age‐related changes in flexibility and automaticity of reasoning about social situations were investigated. Children (N = 101; age range = 7;8–17;7) were presented with the flexibility and automaticity of social cognition (FASC), a new measure of social cognition in which cartoon vignettes of social situations are presented and participants explain what is happening and why. Scenarios vary on whether the scenario is socially ambiguous and whether or not language is used. Flexibility is determined by the number of unique, plausible explanations, and automaticity is indicated by speed of response. Overall, both flexibility and automaticity increased significantly with age. Language and social ambiguity influenced performance. Future work should investigate differences in FASC in older populations and clinical groups.     

Overhearing Brief Negative Messages Has Lasting Effects on Children’s Attitudes Toward Novel Social Groups

Societies are rife with out-group discrimination and mistreatment. One way that children might acquire social biases that lead to such outcomes is by overhearing derogatory or disparaging comments about social groups. Children (n = 121) overheard a video call between a researcher and an adult or child caller who made negative claims (or no claims) about a novel social group. Immediately and following a 2-week delay, older children (7–9 years) who overheard the message demonstrated stronger negative attitudes toward the group than children who heard no message. Younger children’s (4- to 5-year-olds’) attitudes were generally unaffected by these claims. Thus, overhearing brief, indirect messages from children or adults had robust and lasting effects on the social biases of children 7 years and older.     

Social and Cognitive Factors Associated With Children's Secret‐Keeping for a Parent

This study examined children's secret‐keeping for a parent and its relation to trust, theory of mind, secrecy endorsement, and executive functioning (EF). Children (N = 107) between 4 and 12 years of age participated in a procedure wherein parents broke a toy and asked children to promise secrecy. Responses to open‐ended and direct questions were examined. Overall, secret‐keeping increased with age and promising to keep the secret was related to fewer disclosures in open‐ended questioning. Children who kept the secret in direct questioning exhibited greater trust and better parental ratings of EF than children who disclosed the secret. Findings highlight the importance of both social and cognitive factors in secret‐keeping development.     

The Language Growth of Spanish‐Speaking English Language Learners

Although the research literature regarding language growth trajectories is burgeoning, the shape and direction of English Language Learners' (ELLs) language growth trajectories are largely not known. This study used growth curve modeling to determine the shape of ELLs' language growth trajectories across 12,248 oral narrative language samples (6,516 Spanish; 5,732 English) produced by 1,723 ELLs during the first 3 years of formal schooling (M age at first observation = 5 years 7 months). Results indicated distinct trajectories of language growth over time for each language differentially impacted by summer vacation and gender, significant intra‐ and interindividual differences in initial status and growth rates across both languages, and language‐specific relations between language growth and initial status. Implications of ELLs' language growth are discussed.     

Syntactic Cues Help Disambiguate Objects Referred to With Count Nouns: Illustration With Malay Children

Children employ multiple cues to identify the referent of a novel word. Novel words are often embedded in sentences and children have been shown to use syntactic cues to differentiate between types of words (adjective vs. nouns) and between types of nouns (count vs. mass nouns). In this study, we show that children learning Malay (N = 67), a numeral classifier language, can use syntactic cues to perform even finer-grained disambiguation–between count nouns. The manipulation of congruence between lexical and syntactic cues reveals a clear developmental trajectory: while 5-year-olds use predominantly lexical cues, older children increasingly rely on syntactic cues, such that by 7 years of age, they disambiguate between objects referred to with count nouns using syntactic rather than lexical cues.     

Word Reading Fluency: Role of Genome‐Wide Single‐Nucleotide Polymorphisms in Developmental Stability and Correlations With Print Exposure

The genetic effects on individual differences in reading development were examined using genome‐wide complex trait analysis (GCTA) in a twin sample. In unrelated individuals (one twin per pair, n = 2,942), the GCTA‐based heritability of reading fluency was ~20%–29% at ages 7 and 12. GCTA bivariate results showed that the phenotypic stability of reading fluency from 7 to 12 years (r = 0.69) is largely driven by genetic stability (genetic r = 0.69). Genetic effects on print exposure at age 12 were moderate (~26%) and correlated with those influencing reading fluency at 12 (genetic r = 0.89), indicative of a gene–environment correlation. These findings were largely consistent with quantitative genetic twin analyses that used both twins in each pair (n = 1,066–1,409).     

Caregiver Talk and Medical Risk as Predictors of Language Outcomes in Full Term and Preterm Toddlers

This study examined associations between caregiver talk and language skills in full term (FT) and preterm (PT) children (n = 97). All‐day recordings of caregiver–child interactions revealed striking similarities in amount of caregiver talk heard by FT and PT children. Children who heard more caregiver talk at 16 months demonstrated better knowledge‐ and processing‐based language skills at 18 months. The unique contributions of caregiver talk were tempered by medical risk in PT children, especially for processing speed. However, there was no evidence that birth status or medical risk moderated the effects of caregiver talk. These findings highlight the role of caregiver talk in shaping language outcomes in FT and PT children and offer insights into links between neurodevelopmental risk and caregiver–child engagement.     

Online Lexical Competition During Spoken Word Recognition and Word Learning in Children and Adults

Lexical competition that occurs as speech unfolds is a hallmark of adult oral language comprehension crucial to rapid incremental speech processing. This study used pause detection to examine whether lexical competition operates similarly at 7–8 years and tested variables that influence “online” lexical activity in adults. Children (n = 20) and adults (n = 17) were slower to detect pauses in familiar words with later uniqueness points. Faster latencies were obtained for words with late uniqueness points in constraining compared with neutral sentences; no such effect was observed for early unique words. Following exposure to novel competitors (“biscal”), children (n = 18) and adults (n = 18) showed competition for existing words with early uniqueness points (“biscuit”) after 24 hr. Thus, online lexical competition effects are remarkably similar across development.     

Sources of Individual Differences in Children's Understanding of Fractions

Longitudinal associations of domain‐general and numerical competencies with individual differences in children's understanding of fractions were investigated. Children (n = 163) were assessed at 6 years of age on domain‐general (nonverbal reasoning, language, attentive behavior, executive control, visual‐spatial memory) and numerical (number knowledge) competencies; at 7 years on whole‐number arithmetic computations and number line estimation; and at 10 years on fraction concepts. Mediation analyses controlling for general mathematics ability and general academic ability revealed that numerical and mathematical competencies were direct predictors of fraction concepts, whereas domain‐general competencies supported the acquisition of fraction concepts via whole‐number arithmetic computations or number line estimation. Results indicate multiple pathways to fraction competence.     

Semantic Development in Spanish–English Bilingual Children: Effects of Age and Language Experience

This study examines semantic development in 60 Spanish–English bilingual children, ages 7 years 3 months to 9 years 11 months, who differed orthogonally in age (younger, older) and language experience (higher English experience [HEE], higher Spanish experience [HSE]). Children produced 3 associations to 12 pairs of translation equivalents. Older children produced more semantic responses and code switched more often from Spanish to English than younger children. Within each group, children demonstrated better performance in the more frequently used than the less used language. The HEE children outperformed the HSE children in English and the HSE children outperformed the HEE children in Spanish. These effects of age and language experience are consistent with predictions of the revised hierarchical model of bilingual lexical organization.     

Children's Increased Emotional Egocentricity Compared to Adults Is Mediated by Age‐Related Differences in Conflict Processing

This study investigated the cognitive mechanisms underlying age‐related differences in emotional egocentricity bias (EEB) between children (aged 7–12 years, n = 30) and adults (aged 20–30 years, n = 30) using a novel paradigm of visuogustatory stimulation to induce pleasant and unpleasant emotions. Both children and adults showed an EBB, but that of children was larger. The EEB did not correlate with other measures of egocentricity. Crucially, the developmental differences in EEB were mediated by age‐related changes in conflict processing and not visual perspective taking, response inhibition, or processing speed. This indicates that different types of egocentricity develop independently of one another and that the increased ability to overcome EEB can be explained by age‐related improvements in conflict processing.     

Professional Development on the Science of Learning and teachers' Performative Thinking—A Pilot Study

This pilot study investigated how a brief professional development session on the science of learning impacted teachers' attributions of usefulness to both scientific and performative concepts about teaching. Ratings were collected from teachers attending five events across the United Kingdom (N = 585) before and after receiving a 90‐min training session. Initial ratings of scientific concepts were positively correlated with age, while initial ratings of performative concepts were negatively correlated with years of experience. Immediately following professional development, the value teachers attributed to scientific concepts for understanding their practice increased, while their valuing of performative concepts decreased. A follow‐up study with a subsample (N = 153) revealed the impact was reduced but persisted 6–12 weeks later. Results are discussed in terms of the potential for a scientific understanding of learning to empower educators as expert professionals.     

A Path Analysis of Nutrition,Stimulation, and Child Development Among Young Children in Bihar,India

Nutrition plays an important role in the development of a child, particularly in low‐ and middle‐income countries where malnutrition is often widespread. The relation between diet, hemoglobin, nutritional status, motor development, stimulation and mental development was examined in a cross‐sectional sample of 1,079 children 12–18 months of age living in rural Bihar, India. Path analysis revealed associations between (a) length‐for‐age z‐scores and motor development, standardized β (β) = .285, p < .001, and (b) motor and all mental development outcomes (language: β = .422; personal‐social: β = .490; memory: β = .139; and executive function: β = .072, all p < .001). Additionally, stimulation was significantly associated with language scores and hemoglobin concentration with memory. These findings inform interventions aimed at improving child development in Northern India.     

Patterns of coparenting and young children's social–emotional adjustment in low-income families

This study identified coparenting patterns using data collected across 2007–2010 from low-income couples (N = 2915; 26.90% non-Hispanic White; 9.41% non-Hispanic Black; 34.24% Hispanic, 29.27% other or mixed race) with young children (M = 3.65 years; SD = 1.31 years; 48% girls) and examined relations with children's social–emotional adjustment. Latent profile analysis revealed four coparenting patterns: mutual high-quality (43.4%), moderate-quality, mothers less positive (31.8%), moderate-quality, fathers less positive (15.9%), and low-quality, mothers less positive (8.9%). When parents' perspectives on coparenting were positive and congruent, children fared best. Children also fared well when coparenting quality was moderate, and mothers were less positive than fathers. When coparenting quality was moderate and fathers were less positive than mothers, children showed the poorest adjustment.     

Language and reading impairments are associated with increased prevalence of non-right-handedness

Handedness has been studied for association with language-related disorders because of its link with language hemispheric dominance. No clear pattern has emerged, possibly because of small samples, publication bias, and heterogeneous criteria across studies. Non-right-handedness (NRH) frequency was assessed in N = 2503 cases with reading and/or language impairment and N = 4316 sex-matched controls identified from 10 distinct cohorts (age range 6–19 years old; European ethnicity) using a priori set criteria. A meta-analysis (N_cases = 1994) showed elevated NRH % in individuals with language/reading impairment compared with controls (OR = 1.21, CI = 1.06–1.39, p = .01). The association between reading/language impairments and NRH could result from shared pathways underlying brain lateralization, handedness, and cognitive functions.
