Zoom, Zoom, Baby! Assessing Mother-Infant Interaction During the Still Face Paradigm and Infant Language Development via a Virtual Visit Procedure

Adapting language development research paradigms to online testing: Data from preferential looking, word learning and vocabulary assessment in toddlers

During the recent pandemic, it became necessary to adapt lab-based studies to online experiments. To investigate the impact of online testing on the quality of data, we focus on three paradigms widely used in infant research: a word recognition task using the Intermodal Preferential Looking Paradigm, a word learning task using the Switch task, and a language assessment tool (WinG) where children identify a target word amongst a set of picture cards. Our results for synchronous and asynchronous studies provide support for the robustness of online testing. In Experiment 1, robust word recognition was found in 24-month-old toddlers. In Experiment 2, 17-month-old infants consistently learned a new word. Finally, Experiment 3 demonstrated that 19- to 26-month-old children performed well on a language assessment test administered online. Overall, effect sizes or language scores were found to be higher than in lab-based studies. These experiments point to promising possibilities for reaching out to families around the world.

Remote collection of language samples from three-year-olds

We characterised language samples collected remotely from typically developing three-year-olds by comparing them against independent language samples collected in person from age-matched peers with and without language delays. Forty-eight typically developing, English-learning three-year-olds were administered a picture description task via Zoom. The in-person comparison groups were two sets of independent language samples from age-matched typically developing as well as language-delayed children available on the Child Language Data Exchange System. The findings show that although language samples collected remotely from three-year-olds yield numerically dissimilar lexical and grammatical measures compared to samples collected in person, they still consistently distinguish toddlers with and without language delays.

Conducting Developmental Research Online vs. In-Person: A Meta-Analysis

An increasing number of psychological experiments with children are being conducted using online platforms, in part due to the COVID-19 pandemic. Individual replications have compared the findings of particular experiments online and in-person, but the general effect of data collection method on data collected from children is still unknown. Therefore, the goal of the current meta-analysis is to estimate the average difference in effect size for developmental studies conducted online compared to the same studies conducted in-person. Our pre-registered analysis includes 211 effect sizes calculated from 30 papers with 3282 children, ranging in age from four months to six years. The estimated effect size for studies conducted online was slightly smaller than for their counterparts conducted in-person, a difference of d = -.05, but this difference was not significant, 95% CI = [-.17, .07]. We examined several potential moderators of the effect of online testing, including the role of dependent measure (looking vs verbal), online study method (moderated vs unmoderated), and age, but none of these were significant. The literature to date thus suggests-on average-small differences in results between in-person and online experimentation.

"I would be so proud of you guys and myself:" Exploring guided play learning interactions among Black caregivers and their children within a Black history home learning intervention during the COVID-19 pandemic

Existing literature on Black caregiver's interactions with their children has overwhelmingly focused on parenting deficits and interventions designed to "fix" Black families. In utilizing the BlackCreate framework (2023), this study explores how Black caregivers intentionally crafted learning spaces for their children within the context of a six month intervention. Brilliant Joy in a Box was a six-month intervention developed in partnership with a Black woman entrepreneur that delivered caregiver-child Black history home learning boxes to families during the COVID-19 pandemic with the goal of addressing the impacts of persistent historical educational inequities for Black youth, the disproportionate impact of the pandemic Black families, and requests from community members seeking additional programming during the winter months. In the current study, we analyzed videos of 77 families interacting during a guided play activity. We found that the learning spaces created by Black families focused on four subject matters and their domains: literacy, scientific curiosity, math, and identity. We also found that Black caregivers organically utilized guided play to promote joyful interaction and learning. Findings underscore the importance of educators and school staff learning from families in order to reimagine learning and design community based interventions.

Associations between infant amygdala functional connectivity and social engagement following a stressor: A preliminary investigation

Functional architecture of the infant brain, especially functional connectivity (FC) within the amygdala network and between the amygdala and other networks (i.e., default-mode [DMN] and salience [SAL] networks), provides a neural basis for infant socioemotional functioning. Yet, little is known about the extent to which early within- and between-network amygdala FC are related to infant stress recovery across the first year of life. In this study, we examined associations between amygdala FC (i.e., within-network amygdala connectivity, and between-network amygdala connectivity with the DMN and SAL) at 3 months and infant recovery from a mild social stressor at 3, 6 and 9 months. At 3 months, thirty-five infants (13 girls) underwent resting-state functional magnetic resonance imaging during natural sleep. Infants and their mothers completed the still-face paradigm at 3, 6, and 9 months, and infant stress recovery was assessed at each time point as the proportion of infant social engagement during the reunion episode. Bivariate correlations indicated that greater positive within-network amygdala FC and greater positive amygdala-SAL FC, but not amygdala-DMN FC, at 3 months predicted lower levels of stress recovery at 3 and 6 months, but were nonsignificant at 9 months. These findings provide preliminary evidence that early functional synchronization within the amygdala network, as well as segregation between the amygdala and the SAL, may contribute to infant stress recovery in the context of infant-mother interaction.

A realist review of digitally delivered child development assessment and screening tools: Psychometrics and considerations for future use

BACKGROUND

Developmental screening improves the detection of developmental concerns, yet numerous children are not screened/assessed. Remote child developmental tool administration has been utilized to increase screening and assessment accessibility.

METHOD

We conducted a realist review to: (1) identify existing multi-domain child development assessment and screening tools for children 0-5 years; (2) review psychometric data on their digital (i.e., only administered remotely) administration; and (3) explore contextual factors relevant to their digital administration. We searched APA PsycInfo, MEDLINE, CINAHL, and ERIC to identify tools and papers on their psychometrics. We reference-searched included articles and searched Google for relevant grey literature.

RESULTS

Of 33 multi-domain child development tools identified in objective one, five tools (in five studies) were delivered digitally and compared to traditional (e.g., paper) delivery (i.e., objective two). Studies evaluated within-group equivalence reliability (k = 2) and between-group equivalence (k = 3). Within-group equivalence reliability was established for the Vineland Adaptive Behavior Scales, and domains (e.g., gross motor) of the Ages and Stages Questionnaires 2nd edition (ASQ-2) and Revised Prescreening Denver Questionnaire (R-PDQ). Between group equivalence was demonstrated for Developmental Neuropsychological Assessment, 2nd Edition (NEPSY-II) subtests and Bayley Scales of Infant and Toddler Development, 3rd edition (Bayley-3) items. In another between group evaluation, web-based and paper versions of the ASQ-2 were deemed generally equivalent. Digital Bayley-3 inter-observer reliability ranged from 0.82 to 1.0. Examiner support, time, tool modifications, family resources, and comfort promotion supported digital administration.

CONCLUSION

Digitally delivered ASQ-2, R-PDQ, Vineland, and Bayley-3 and NEPSY-II components show promise for equivalence with traditional administration.

Functional neural network connectivity at 3 months predicts infant-mother dyadic flexibility during play at 6 months

Early functioning of neural networks likely underlies the flexible switching between internal and external orientation and may be key to the infant's ability to effectively engage in social interactions. To test this hypothesis, we examined the association between infants' neural networks at 3 months and infant-mother dyadic flexibility (denoting the structural variability of their interaction dynamics) at 3, 6, and 9 months. Participants included thirty-five infants (37% girls) and their mothers (87% White). At 3 months, infants participated in a resting-state functional magnetic resonance imaging session, and functional connectivity (FC) within the default mode (DMN) and salience (SN) networks, as well as DMN-SN internetwork FC, were derived using a seed-based approach. When infants were 3, 6, and 9 months, infant-mother dyads completed the Still-Face Paradigm where their individual engagement behaviors were observed and used to quantify dyadic flexibility using state space analysis. Results revealed that greater within-DMN FC, within-SN FC, and DMN-SN anticorrelation at 3 months predicted greater dyadic flexibility at 6 months, but not at 3 and 9 months. Findings suggest that early synchronization and interaction between neural networks underlying introspection and salience detection may support infants' flexible social interactions as they become increasingly active and engaged social partners.

Exploring individual differences in infants' looking preferences for impossible events: The Early Multidimensional Curiosity Scale

Infants are drawn to events that violate their expectations about the world: they look longer at physically impossible events, such as when a car passes through a wall. Here, we examined whether individual differences in infants' visual preferences for physically impossible events reflect an early form of curiosity, and asked whether caregivers' behaviors, parenting styles, and everyday routines relate to these differences. In Study 1, we presented infants (N = 47, Mage  = 16.83 months, range = 10.29-24.59 months) with events that violated physical principles and closely matched possible events. We measured infants' everyday curiosity and related experiences (i.e., caregiver curiosity-promoting activities) through a newly developed curiosity scale, The Early Multidimensional Curiosity Scale (EMCS). Infants' looking preferences for physically impossible events were positively associated with their score on the EMCS, but not their temperament, vocabulary, or caregiver trait curiosity. In Study 2A, we set out to better understand the relation between the EMCS and infants' looking preferences for physically impossible events by assessing the underlying structure of the EMCS with a larger sample of children (N = 211, Mage  = 47.63 months, range = 10.29-78.97 months). An exploratory factor analysis revealed that children's curiosity was comprised four factors: Social Curiosity, Broad Exploration, Persistence, and Information-Seeking. Relatedly, caregiver curiosity-promoting activities were composed of five factors: Flexible Problem-Solving, Cognitive Stimulation, Diverse Daily Activities, Child-Directed Play, and Awe-Inducing Activities. In Study 2B (N = 42 infants from Study 1), we examined which aspects of infant curiosity and caregiver behavior predicted infants' looking preferences using the factor structures of the EMCS. Findings revealed that infants' looking preferences were uniquely related to infants' Broad Exploration and caregivers' Awe-Inducing Activities (e.g., nature walks with infants, museum outings). These exploratory findings indicate that infants' visual preferences for physically impossible events may reflect an early form of curiosity, which is related to the curiosity-stimulating environments provided by caregivers. Moreover, this work offers a new comprehensive tool, the Early Multidimensional Curiosity Scale, that can be used to measure both curiosity and factors related to its development, starting in infancy and extending into childhood.
