RESUMEN

In Western societies, social contingency, or prompt and meaningful back-and-forth exchanges between infant and caregiver, is a powerful feature of the early language environment. Research suggests that infants with better attentional skills engage in more social contingency during interactions with adults and, in turn, social contingency supports infant attention. This reciprocity is theorized to build infant language skills as the adult capitalizes on and extends the infant's attention during socially contingent interactions. Using data from 104 infants and caregivers, this paper tests reciprocal relations between infant attention and social contingency at 6- and 12-months and the implications for infant vocabulary at 18-months. Infant attentional skills to social (women speaking) and nonsocial (objects dropping) events were assessed, and social contingency was examined during an 8-minute toy play interaction with a caregiver. Child receptive and expressive vocabulary was measured by caregiver-report. Both social and nonsocial attentional skills related to engagement in social contingency during caregiver-infant interaction, though only models that included social attention and social contingency predicted vocabulary. These findings provide empirical evidence for the proposed reciprocal relations between infant attention and social contingency as well as how they relate to later language.

RESUMEN

Research suggests foster children are at risk for poor language skills. One intervention, attachment and biobehavioral catch-up (ABC), was shown to successfully improve not only young foster children's attachment to their parents, but also their receptive vocabulary skills (Bernard et al., 2017; Raby et al., 2019). Given that language acquisition is intricately linked to parents' sensitive interactions with their children, we ask whether the ABC intervention also improves the quality of parents' talk addressed to children. We test whether the ABC intervention results in more conversational turns between parents and their children. Crucially, we also look within these conversational turns, assessing the number and types of questions that parents ask children. Results suggest that parents who received the ABC intervention do not have more conversational turns or ask higher numbers of questions, compared to parents who received the control intervention. Rather, parents in the ABC group ask a higher proportion of child-led and restatement questions, and a lower proportion of parent-led and pedagogical questions, compared to the control. Additionally, the higher proportion of child-led questions were related to higher parental sensitivity scores. Together, these results suggest that an intervention originally designed to improve children's socioemotional outcomes had positive benefits for the quality of conversations between parents and children.

RESUMEN

A growing body of evidence from the science of learning demonstrates the educational effectiveness of active, playful learning. Connections are emerging between this pedagogy and the broad set of skills that it promotes in learners, but potential mechanisms behind these relations remain unexplored. This paper offers a commentary based on the science of learning and interest development literature, suggesting that interest may mediate the relation between active, playful learning and student outcomes. This theory is established by identifying principles of active, playful learning that predict interest development and associations between learner interest and key skills for success in the classroom and beyond. Future research should investigate the dynamic relation between active, playful learning, interest, and student achievement over time and across phases of interest while taking a broader set of student outcomes into account.

RESUMEN

It is well known that infants undergo developmental change in how they respond to language-relevant visual contrasts. For example, when viewing motion events, infants' sensitivities to background information ("ground-path cues," e.g., whether a background is flat and continuous or bounded) change with age. Prior studies with English and Japanese monolingual infants have demonstrated that 14-month-old infants discriminate between motion events that take place against different ground-paths (e.g., an unbounded field vs a bounded street). By 19 months of age, this sensitivity becomes more selective in monolingual infants; only learners of languages that lexically contrast these categories, such as Japanese, discriminate between such events. In this study, we investigated this progression in bilingual infants. We first replicated past reports of an age-related decline in ground-path sensitivity from 14 to 19 months in English monolingual infants living in a multilingual society. English-Mandarin bilingual infants living in that same society were then tested on discrimination of ground-path cues at 14, 19, and 24 months. Although neither the English nor Mandarin language differentiates motion events based on ground-path cues, bilingual infants demonstrated protracted sensitivity to these cues. Infants exhibited a lack of discrimination at 14 months, followed by discrimination at 19 months and a subsequent decline in discrimination at 24 months. In addition, bilingual infants demonstrated more fine-grained sensitivities to subtle ground cues not observed in monolingual infants.

RESUMEN

High-quality communicative interactions between caregivers and children provide a foundation for children's social and cognitive skills. Although most studies examining these types of interactions focus on child language outcomes, this paper takes another tack. It examines whether communicative, dyadic interactions might also relate to child executive function (EF) skills and whether child language might mediate this relation. Using a subset of data from the NICHD Study of Early Child Care and Youth Development, dyadic interactions between 2-year-olds and their mothers were coded for three behaviors: symbol-infused joint engagement, routines and rituals, and fluency and connectedness. Child language was assessed at age 3 and three facets of EF (self-regulation, sustained attention, and verbal working memory) were assessed at age 4.5. Structural equation modeling showed that dyadic interaction related to later child sustained attention and verbal working memory, indirectly through child language and directly related with child self-regulation. This suggests that communicative interactions with caregivers that include both verbal and non-verbal elements relate to child EF, in part through child language. Our findings have implications for the role of caregiver interactions in the development of language and cognitive skills more broadly. RESEARCH HIGHLIGHTS: Using structural equation modeling, we examined how communicative interactions between caregivers and toddlers relate to preschool executive function skills Communicative interactions relate to later language which in turn relates to sustained attention and verbal working memory in preschool Communicative interactions relate directly to self-regulation in preschool Associations between communicative interactions, language, and executive function vary across facets of executive function and may not be unidirectional.

RESUMEN

INTRODUCTION: This research examined the classification accuracy of the Quick Interactive Language Screener (QUILS) for identifying preschool-aged children (3;0 to 6;9) with developmental language disorder (DLD). We present data from two independent samples that varied in prevalence and diagnostic reference standard. METHODS: Study 1 included a clinical sample of children (54 with DLD; 13 without) who completed the QUILS and a standardized assessment of expressive grammar (Syntax subtest from the Diagnostic Evaluation of Language Variation-Norm Referenced; Structured Photographic Expressive Language Test-Preschool 2nd Edition; or Structured Photographic Expressive Language Test-3 rd Edition). Study 2 included a community sample of children (25 with DLD; 101 without) who completed the QUILS and the Auditory Comprehension subtest of the Preschool Language Scales-5th Edition (PLS-5; Zimmerman et al., 2011). Discriminant analyses were conducted to compare classification accuracy (i.e., sensitivity and specificity) using the normreferenced cut score (< 25th percentile) with empirically derived cut scores. RESULTS: In Study 1, the QUILS led to low fail rates (i.e., high specificity) in children without impairment and statistically significant group differences as a function of children's clinical status; however, only 65% of children with DLD were accurately identified using the norm-referenced cutoff. In Study 2, 76% of children with DLD were accurately identified at the 25th percentile cutoff and accuracy improved to 84% when an empirically derived cutoff (<32nd percentile) was applied. CONCLUSIONS: Findings support the clinical application of the QUILS as a component of the screening process for identifying the presence or absence of DLD in community samples of preschool-aged children.

RESUMEN

Although questions fuel children's learning, adult cell phone use may preoccupy parents, affecting the frequency of questions parents and children ask and answer. We ask whether parental cell phone use will lead to a decrease in the number of questions children and parents ask one another while playing with a novel toy. Fifty-seven parent-child dyads (Mage = 48.72 months, SD = 6.53, 28 girls; 84.2% White) were randomly assigned to a cell phone, paper, or control condition. As children played with a novel toy with hidden functions, parents in the cell phone condition completed a survey about reading on their cell phone, while parents in the paper condition did it on paper. Parents in the control condition did not complete the survey. Results suggest that children asked fewer questions in the cell phone than in the control condition. However, no other condition differences emerged. Parents' information-seeking questioning, however, differed in all three conditions: they asked more in the control than in the cell phone and paper conditions and, critically, asked more in the paper than cell phone condition. Possible explanations and implications for parents' cell phone use are discussed. (PsycInfo Database Record (c) 2022 APA, all rights reserved).

RESUMEN

Spatial skills support STEM learning and achievement. However, children from low-socioeconomic (SES) backgrounds typically lag behind their middle- and high-SES peers. We asked whether a digital educational app-designed to mirror an already successful, spatial assembly training program using concrete materials-would be as effective for facilitating spatial skills in under-resourced preschoolers as the concrete materials. Three-year-olds (N = 61) from under-resourced backgrounds were randomly assigned to a business-as-usual control group or to receive 5 weeks of spatial training using either concrete, tangible materials or a digital app on a tablet. The spatial puzzles used were an extension of items from the Test of Spatial Assembly (TOSA). Preschoolers were pretested and posttested on new two-dimensional (2D) TOSA trials. Results indicate that both concrete and digital spatial training increased performance on the 2D-TOSA compared to the control group. The two trainings did not statistically differ from one another suggesting that educational spatial apps may be one route to providing early foundational skills to children from under-resourced backgrounds.

RESUMEN

Public space interventions offer one example of how to translate cognitive science into the public square. Here, we detail several successful projects and the six principles of learning that underlie them that support caregiver-child engagement, interaction, and the use of content area-specific language. Policy and community implications are also discussed.

RESUMEN

Creativity is typically measured using divergent thinking tasks where participants are asked to generate multiple responses following a prompt. However, being able to generate responses captures only a partial picture of creativity. Convergent thinking, in which a single solution is chosen, is an equally important part of creativity that is often left out of divergent thinking assessments. Moreover, as the field of creativity evolves, exploration is starting to be recognized as an understudied component of how children generate and apply creative solutions. The current study moved beyond typical divergent thinking tasks and examined a measure of creativity that also captured 4- to 6-year-old children's convergent thinking and exploration behaviors. A total of 130 children participated in a creative problem-solving task where they were asked to remove a ball from a jar using everyday objects. Children's actions were coded as divergent thinking, convergent thinking, or exploration behaviors. Results demonstrated that divergent and convergent thinking performance was not associated with success on the task, indicating that simply generating and selecting more responses is not always enough to achieve a creative outcome. Children's exploration behaviors were positively associated with success on the task. Exploration behaviors were more likely to lead to success if they were purposeful and iterative. These findings provide some of the first evidence that children's exploration is a vital component of creativity.

RESUMEN

Experts have expressed concerns about the lack of evidence demonstrating that children's "educational" applications (apps) have educational value. This study aimed to operationalize Hirsh-Pasek, Zosh, et al.'s (2015) Four Pillars of Learning into a reliable coding scheme (Pillar 1: Active Learning, Pillar 2: Engagement in the Learning Process, Pillar 3: Meaningful Learning, Pillar 4: Social Interaction), describe the educational quality of commercially-available apps, and examine differences in educational quality between free and paid apps. We analyzed 100 children's educational apps with the highest downloads from Google Play and Apple app stores, as well as 24 apps most frequently played by preschool-age children in a longitudinal cohort study. We developed a coding scheme in which each app earned a value of 0-3 for each Pillar, defining lower-quality apps as those scoring ≤ 4, summed across the Four Pillars. Overall scores were low across all Pillars. Free apps had significantly lower Pillar 2 (Engagement in Learning Process) scores (t-test, p < .0001) and overall scores (t-test, p < .0047) when compared to paid apps, due to the presence of distracting enhancements. These results highlight the need for improved design of educational apps guided by developmental science.

RESUMEN

Infants from low-socioeconomic status (SES) households hear a projected 30 million fewer words than their higher-SES peers. In a recent study, Hirsh-Pasek et al. (Psychological Science, 2015; 26: 1071) found that in a low-income sample, fluency and connectedness in exchanges between caregivers and toddlers predicted child language a year later over and above quantity of talk (Hirsh-Pasek et al., Psychological Science, 2015; 26: 1071). Here, we expand upon this study by examining fluency and connectedness in two higher-SES samples. Using data from the NICHD Study of Early Child Care and Youth Development, we sampled 20 toddlers who had low, average, and high language outcomes at 36 months from each of 2 groups based on income-to-needs ratio (INR; middle and high) and applied new coding to the mother-toddler interaction at 24 months. In the high-INR group, the quality of mother-toddler interaction at 24 months accounted for more variability in language outcomes a year later than did quantity of talk, quality of talk, or sensitive parenting. These results could not be accounted for by child language ability at 24 months. These effects were not found in the middle-INR sample. Our findings suggest that when the quality of interaction, fluency and connectedness, predicts language outcomes, it is a robust relation, but it may not be universal.

RESUMEN

During the unprecedented coronavirus disease (COVID-19) crisis, virtual education activities have become more prevalent than ever. One activity that many families have incorporated into their routines while at home is virtual storytime, with teachers, grandparents, and other remote adults reading books to children over video chat. The current study asks how dialogic reading over video chat compares to more traditional forms of book reading in promoting story comprehension and vocabulary learning. Fifty-eight 4-year-olds (M age = 52.7, SD = 4.04, 31 girls) were randomly assigned to one of three conditions (Video chat, Live, and Prerecorded). Across conditions, children were read the same narrative storybook by a female experimenter who used the same 10 scripted dialogic reading prompts during book reading. In the Video chat (n = 21) and Live conditions (n = 18), the experimenter gave the scripted prompts and interacted naturally and contingently, responding in a timely, relevant manner to children's behaviors. In the Prerecorded condition (n = 19), children viewed a video of an experimenter reading the book. The Prerecorded condition was pseudo-contingent; the reader posed questions and paused for a set period of time as if to wait for a child's response. After reading, children completed measures of vocabulary and comprehension. Results revealed no differences between conditions across six different outcome measures, suggesting that children comprehended and learned from the story similarly across book formats. Further, children in the three experimental conditions scored significantly higher on measures than children in a fourth condition (control) who had never read the book, confirming that children learned from the three different book formats. However, children were more responsive to the prompts in the Live and Video chat conditions than the Prerecorded condition, suggesting that children recognized that these interactions were contingent with their responses, a feature that was lacking in the Prerecorded condition. Results indicate that children can comprehend books over video chat, suggesting that this technology is a viable option for reading to children, especially during the current pandemic.

RESUMEN

Early spatial skills predict the development of later spatial and mathematical skills. Yet, it is unclear how comprehension of the words that capture spatial relations, words like behind and under, might be associated with children's early spatial and mathematics skills. The current study addressed this question by conducting a moderated mediation model to test the potential moderating effects of group factors, such as socioeconomic status (SES) and gender, on the possible mediation of spatial language comprehension on the association between spatial skill and mathematics performance. In total, 192 3-year-olds were tested on a battery of assessments, including a novel Spatial Language Comprehension Task, a test of spatial skills (2- and 3-dimensional trials of the Test of Spatial Assembly [2D and 3D TOSA, respectively]), and a composite of 2 mathematical assessments. The results indicate that this novel Spatial Language Comprehension Task is a reliable measure useful for examining group differences and the early space-math link. Specifically, higher-SES preschoolers and females had higher spatial language comprehension compared with their lower-SES peers and males, respectively. These SES and gender disparities in spatial language comprehension are concerning, given the strong association between spatial language comprehension and mathematics skills. Additionally, spatial language comprehension mediated the association between spatial skill and mathematics performance for females only. Future work should examine the potential causal role that spatial language comprehension may have in concurrent and later spatial and mathematics skills.

RESUMEN

Spatial skills are associated with mathematics skills, but it is unclear if spatial training transfers to mathematics skills for preschoolers, especially from underserved communities. The current study tested (a) whether spatial training benefited preschoolers' spatial and mathematics skills, (b) if the type of feedback provided during spatial training differentially influenced children's spatial and mathematics skills, and (c) if the spatial training's effects varied by socioeconomic status (SES). Preschoolers (N = 187) were randomly assigned to either a 'business-as-usual' control or one of three spatial training groups (modeling and feedback [MF]; gesture feedback [GF]; spatial language feedback [SLF]). Three-year-olds were trained to construct puzzles to match a model composed of various geometric shapes. New models were created similar to the 2-dimensional trials of the Test of Spatial Assembly (TOSA). Training was given once per week for 5 weeks. Preschoolers were pretested and posttested on 2D and 3D TOSA trials, spatial vocabulary, shape identification, and 2 mathematics assessments. Results indicate that first, any spatial training improved preschoolers' 2D TOSA performance, although a significant interaction with SES indicated improvement was driven by low-SES children. Furthermore, low-SES children showed greatest gains on the 2D TOSA with MF and GF. Second, MF and GF improved low-SES children's performance on the 3D TOSA. Third, only low-SES children with MF saw improvements in far-transfer to mathematics (Woodcock-Johnson: Applied Problems, but not the Test of Early Mathematical Ability). Results indicate that, especially for low-income learners, spatial training can improve children's early spatial and mathematics skills.

RESUMEN

Infants must learn to carve events at their joints to best understand who is doing what to whom or whether an object or agent has reached its intended goal. Recent behavioral research demonstrates that infants do not see the world as a movie devoid of meaning, but rather as a series of sub-events that include agents moving in different manners along paths from sources to goals. This research uses behavioral and electrophysiological methods to investigate infants' (10-14 months) attention to disruptions within relatively unfamiliar human action that does not rely on goal-objects to signal attainment (i.e., Olympic figure skating). Infants' visual (Study 1, N = 48) and neurophysiological (Study 2, N = 21) responses to pauses at starting points, endpoints, and within-action locations were recorded. Both measures revealed differential responses to pauses at endpoints relative to pauses elsewhere in the action (i.e., starting point; within-action). Eye-tracking data indicated that infants' visual attention was greater for events containing pauses at endpoints relative to events with pauses at starting points or within-actions. ERP activity reflecting perceptual processes in early-latency windows (<200 ms) and memory updating processes in long-latency windows (700-1000 ms) showed differential activation to disruptions at the end of a figure-skating action compared to other locations. Mid-latency windows (250-750 ms), in contrast, showed enhanced activation at frontal regions across conditions, suggesting electrophysiological resources may have been recruited to encode disruptions within unfamiliar dynamic human action. Combined, results hint at broad sensitivity to endpoints as a mechanism that supports infants' proclivity for carving continuous and complex event streams into meaningful units. Findings have potential implications for language development as these units are mapped onto budding linguistic representations. We discuss empirical and methodological contributions for action perception and address potential merits and pitfalls of applying behavioral techniques in conjunction with brain-based measures to study infant development.

RESUMEN

Block-building skills at age 3 are related to spatial skills at age 5 and spatial skills in grade school are linked to later success in science, technology, engineering, and mathematics (STEM) fields (Wai, Lubinski, & Benbow, 2009; Wai, Lubinski, Benbow, & Steiger, 2010). Though studies have focused on block-building behaviors and design complexity, few have examined these variables in relation to future spatial and mathematical skills or have considered how children go about copying the model in detail. This study coded 3-year-olds' (N = 102) block-building behaviors and structural complexity on 3-D trials of the Test of Spatial Assembly (TOSA; Verdine, Golinkoff, Hirsh-Pasek, & Newcombe, 2017). It explored whether individual differences in children's building behaviors and the complexity of their designs related to accuracy in copying the model block structures or their spatial and mathematical skills at ages 4 and 5. Our findings reveal that block-building behaviors were associated with concurrent and later spatial skills while structural complexity was associated with concurrent and later spatial skills as well as concurrent mathematics skills. Future work might teach children to engage in the apparently successful block-building strategies examined in this research to evaluate a potential causal mechanism.

RESUMEN

Verb extension is a crucial gauge of the acquisition of verb meaning. In English, studies suggest that young children show conservative extension. An important test of whether an early conservative extension is a general phenomenon or a function of the input language is made possible by Chinese, a language in which verbs are more frequent and acquired earlier. This study tested whether 3-year-old Chinese children extended a group of familiar verbs that specify various ways to carry objects. Shown videos that portrayed typical, mid-typical, or atypical carrying actions (as verified by Chinese adults), children were asked to judge whether they were examples of specific Chinese carry verbs. Children's verb extensions were mostly limited to typical exemplars, suggesting that an early conservative extension may be universal. Furthermore, extension breadth was related to the onset of verb production: verbs acquired earlier elicited more extension judgments than those acquired later.
