  • Peer and familial influences on the association between behavioral inhibition and trajectories of social anxiety symptoms across adolescence

    Open AccessMadison Politte‐Corn, Sarah Myruski et al.ARTICLEJournal of Research on Adolescence2026

    Behavioral inhibition (BI) is one of the most reliable predictors of social anxiety, and both peers and family members play a key role in shaping this association. In a sample of adolescents enriched for elevated BI and social anxiety symptoms, we examined (1) the moderating role of familial and close peer relationship qualities on associations between BI, concurrent social anxiety symptoms, and social anxiety symptom trajectories and (2) indirec…

  • When the World Pivots: Changes in Infant Negative Affect Trajectories Following the Onset of the Covid‐19 Pandemic

    Open AccessJoscelin Rocha‐hidalgo, Brendan Ostlund et al.ARTICLEInfancy2025

    Research on the COVID‐19 pandemic's effect on infant emotional development has produced mixed results, often limited by methodological constraints, such as not having access to data prior to and after pandemic onset. This study helps overcome these limitations by analyzing data from 330 infants (51% female; 54% White, non‐Hispanic) across five points in the first 2 years of life, from October 2016 to August 2021. Multilevel growth models indicate…

  • The Infant Behavior Questionnaire Factor Structure Varies With Sample Characteristics

    Open AccessAnna M Zhou, Koraly E Pérez‐edgar et al.ARTICLEInfancy2025

    The Infant Behavior Questionnaire (IBQ) has been widely used to assess infant temperament traits, though there is limited empirical support for the recommended three‐factor structure. The present study examined the replicability and measurement invariance in the IBQ using a large, multi‐site longitudinal study of parent‐child dyads ( N = 357) in the United States. Temperament was reported by parents when infants were 4‐, 8‐ and 12‐months of age. …

  • Emotional Reactivity and Internalizing Symptoms in Middle Childhood: Integrating Autonomic and Behavioral Markers of Social Fear and Positive Affect

    Open AccessMadison Politte‐Corn, Rebecca J Brooker et al.ARTICLEDevelopmental Psychobiology2025References: 85

    Emotional reactivity is a well‐validated corollary of children's risk for internalizing psychopathology and can be indexed by autonomic and behavioral measures. Yet, it is unclear whether and how autonomic and behavioral markers of emotional reactivity interact to characterize internalizing symptoms and whether these associations differ based on emotional context. As such, the current study aimed to (1) clarify associations between autonomic (RSA…

  • Developmental Trajectories of Delta–Beta EEG Coupling Across Infancy: The Influence of Infant Temperament and Maternal Anxiety Over Time

    Open AccessBerenice Anaya, Brendan Ostlund et al.ARTICLEDevelopmental Psychobiology2025References: 61

    Coupling, or the correlation, between delta and beta EEG power may underly regulatory processes. Stronger, positive delta–beta coupling is associated with anxiety and fearful temperament, potentially tracking dysregulation. However, most studies have reported on cross‐sectional investigations of delta–beta coupling in children. Thus, the normative development of delta–beta coupling remains poorly understood. Here, we leveraged a diverse sample ( …

  • Parent‐Reported Toddler Dysregulation and Respiratory Sinus Arrhythmia Predict Trajectories of Childhood Externalizing Behaviors

    Open AccessMichelle L Ramos, Anna M Zhou et al.ARTICLEDevelopmental Psychobiology2025References: 83

    Externalizing behaviors (e.g., aggression, oppositionality, conduct problems) typically peak then decrease across early childhood (ages 2–5). However, some children continue to exhibit elevated levels of externalizing behavior throughout childhood, which can have implications for later socioemotional difficulties. Emotion regulation (ER) is an early predictor of continuity in externalizing behaviors. Toddlers with poor ER are more likely to exhib…

  • The Influence of Neighborhood on Infant Parasympathetic Nervous System Development

    Open AccessMarisa N Lytle, Anna M Zhou et al.ARTICLEDevelopmental Psychobiology2025References: 80

    The adaptive calibration model (ACM) asserts that the stress response system, including the parasympathetic nervous system (PNS), conditionally adapts to one's environment. In infancy, the proximal context of parental influences (e.g., maternal depression/anxiety) affects the development of the infant stress response system. In contrast, the relation between broader contexts, such as neighborhood environment, and infant PNS development is less we…

  • Adolescent coping and social media use moderated anxiety change during the Covid‐19 pandemic

    Open AccessSarah Myruski, Koraly Pérez‐edgar et al.ARTICLEJournal of Adolescence2024

    INTRODUCTION: Adolescence is a sensitive period during which stressors and social disruptions uniquely contribute to anxiety symptoms. Adolescent's coping strategies (i.e., avoidance and approach) during the coronavirus disease 2019 (COVID-19) pandemic may be differentially related to anxiety symptom changes. Further, social media use (SMU) is ubiquitous and may serve as an avenue to deploy avoidant and/or approach coping. METHOD: Participants in…

  • Visual and behavioral responses to social and non-social threats: A multi-site replication

    Open AccessJessica L Burris, Lori B Reider et al.ARTICLEActa Psychologica2024

    Researchers have proposed that humans have evolved psychological mechanisms that facilitate the detection, rapid response, and subsequent avoidance of potential threats. However, some inconsistent results in the literature have called into question the robustness of these responses. Here, we sought to replicate previous findings on the rapid detection of both social (i.e., angry faces) and nonsocial (i.e., snakes) threats within a large and diver…

  • Individual differences in developmental trajectories of affective attention and relations with competence and social reticence with peers

    Open AccessAlicia Vallorani, Kelley E Gunther et al.ARTICLEEmotion2024

    This study examined individual differences in affective attention trajectories in infancy and relations with competence and social reticence at 24 months. Data collection spanned 2017 to 2021. Infants ( N = 297, 53% White, 49% reported as assigned male at birth) recruited in South Central and Central Pennsylvania and Northern New Jersey provided eye-tracking data at five assessments. Caregivers self-reported anxiety symptoms, infant temperamental…

  • A functionalist perspective of young children’s anger and sadness

    Open AccessGabrielle Sky Cardwell, Pamela M Cole et al.ARTICLEEmotion2024

    Functional emotion theory defines anger as appraisal that a goal is blocked and readiness to act to overcome the obstacle-to approach, and sadness as appraisal that a goal is lost and readiness to relinquish effort-to withdraw. We test relations between these emotions and actions in young children during a blocked reward task, specifically associations in (a) anger and approach toward the goal, (b) sadness and withdrawal from the goal, and (c) gr…

  • Categorical and latent profile approaches to temperamental infant reactivity and early trajectories of socioemotional adjustment

    Open AccessBerenice Anaya, Laura Bierstedt et al.ARTICLEDevelopmental Psychology2024References: 3

    This article examines the patterns, and consequences, of infant temperamental reactivity to novel sensory input in a large ( N = 357; 271 in current analysis) and diverse longitudinal sample through two approaches. First, we examined profiles of reactivity in 4-month-old infants using the traditional theory-driven analytic approach laid out by Jerome Kagan and colleagues, and derived groups characterized by extreme patterns of negative reactivity…

  • Developmental differences in young children's implied use of cognitive resources in their self‐regulation strategies

    Open AccessGabrielle Sky Cardwell, Pamela M Cole et al.ARTICLESocial Development2024Cited by: 1References: 1

    The emergence of self‐regulation during the preschool years is due, in part, to children's development of cognitive resources that can regulate their behavior. However, there is little direct evidence that age influences the extent to which young children's strategies involve such resources. We investigated age differences in the extent that young children's strategies imply cognitive resources. A sample of 154 children (77 girls; M age 45.15 mon…

  • Assessing bidirectional relations between infant temperamental negative affect, maternal anxiety symptoms and infant affect-biased attention across the first 24-months of life

    Open AccessAlicia Vallorani, Kelley E Gunther et al.ARTICLEDevelopmental Psychology2023References: 3

    Developmental theories suggest affect-biased attention, preferential attention to emotionally salient stimuli, emerges during infancy through coordinating individual differences. Here we examined bidirectional relations between infant affect-biased attention, temperamental negative affect, and maternal anxiety symptoms using a Random Intercepts Cross-Lagged Panel model (RI-CLPM). Infant-mother pairs from Central Pennsylvania and Northern New Jers…

  • Developmental patterns of affective attention across the first 2 years of life

    Open AccessLori B Reider, Laura Bierstedt et al.ARTICLEChild Development2022

    This study examined patterns of attention toward affective stimuli in a longitudinal sample of typically developing infants (N = 357, 147 females, 50% White, 22% Latinx, 16% African American/Black, 3% Asian, 8% mixed race, 1% not reported) using two eye-tracking tasks that measure vigilance to (rapid detection), engagement with (total looking toward), and disengagement from (latency to looking away) emotional facial configurations. Infants comple…

  • Study Protocol: Longitudinal Attention and Temperament Study

    Open AccessKoraly E Pérez‐edgar, Vanessa Lobue et al.ARTICLEFrontiers in Psychiatry2021

    Background: Attention processes may play a central role in shaping trajectories of socioemotional development. Individuals who are clinically anxious or have high levels of trait anxiety sometimes show attention biases to threat. There is emerging evidence that young children also demonstrate a link between attention bias to salient stimuli and broad socioemotional profiles. However, we do not have a systematic and comprehensive assessment of how…

  • Capturing temporal dynamics of fear behaviors on a moment‐to‐moment basis

    Open AccessElizabeth A Shewark, Timothy R Brick et al.ARTICLEInfancy2020

    Identifying patterns of fearful behaviors early and accurately is essential to identify children who may be at increased risk for psychopathology. Previous work focused on the total amount of fear by using composites across time. However, considering the temporal dynamics of fear expression might offer novel insights into the identification of children at risk. One hundred and twenty‐five toddlers participated in high‐ and low‐fear tasks. Data we…

  • Individual differences in infancy research: Letting the baby stand out from the crowd

    Open AccessKoraly E Pérez‐edgar, Alicia Vallorani et al.ARTICLEInfancy2020

    Within the developmental literature, there is an often unspoken tension between studies that aim to capture broad scale, fairly universal nomothetic traits, and studies that focus on mechanisms and trajectories that are idiographic and bounded to some extent by systematic individual differences. The suitability of these approaches varies as a function of the specific research interests at hand. Although the approaches are interdependent, they hav…

  • The importance of using multiple outcome measures in infant research

    Open AccessVanessa Lobue, Lori B Reider et al.ARTICLEInfancy2020

    Collecting data with infants is notoriously difficult. As a result, many of our studies consist of small samples, with only a single measure, in a single age group, at a single time point. With renewed calls for greater academic rigor in data collection practices, using multiple outcome measures in infant research is one way to increase rigor, and, at the same time, enable us to more accurately interpret our data. Here, we illustrate the importan…

  • Maternal Accuracy for Children’s Fearful Distress in Toddlerhood and Kindergarten: Moderation of a Serial Indirect Effect by Toddler Fearful Temperament

    Elizabeth J Kiel, Anne E Kalomiris et al.ARTICLEParenting2020References: 10

    Maternal accuracy may be maintained across early childhood through the interactions mothers have with their temperamentally fearful children. Given concurrent measurement of some of the variables, the role of maternal cognitions like maternal accuracy should be replicated and then further considered for inclusion in theories and studies of transactional influences between parents and children on development

  • Maternal anxiety and toddler inhibited temperament predict maternal socialization of worry

    Open AccessElizabeth J Kiel, Natalee N Price et al.ARTICLESocial Development2020References: 7

    Parent emotion socialization refers to the process by which parents impart their values and beliefs about emotion expressivity to their children. Parent emotion socialization requires attention as a construct that develops in its own right. The socialization of child worry, in particular, has implications for children's typical socioemotional development, as well as their maladaptive development towards anxiety outcomes. Existing theories on emot…

  • Developmental Differences in Infants' Attention to Social and Nonsocial Threats

    Open AccessVanessa Lobue, Kimberly A Bu et al.ARTICLEInfancy2017

    Research has demonstrated that humans detect threatening stimuli more rapidly than nonthreatening stimuli. Although the literature presumes that biases for threat should be normative, present early in development, evident across multiple forms of threat, and stable across individuals, developmental work in this area is limited. Here, we examine the developmental differences in infants' (4‐ to 24‐month‐olds) attention to social (angry faces) and n…
