The roles of parental verbal communication and child characteristics in the transmission and maintenance of social fears
BACKGROUND: Although social anxiety runs in families, little is known about how parents and children contribute to the intergenerational transmission of social fears. We examined whether mothers transfer social fear beliefs to their children through verbal communication and how children's behavioral inhibition and social anxiety contribute to this transmission. The associations of children's social fear beliefs with peer avoidance and interpretat…
When the World Pivots
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
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. …
Developmental Trajectories of Delta–Beta EEG Coupling Across Infancy
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 ( …
The Influence of Neighborhood on Infant Parasympathetic Nervous System Development
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…
Constructing the “Family Personality
INTRODUCTION: Early child development occurs within an interactive environment, initially dominated by parents or caregivers, and is heavily influenced by the dynamics of this social context. The current study probed the neurobiology of "family personality", or family functioning, in the context of parent-child dyadic interaction using a two-person neuroimaging modality. METHODS: One hundred and five parent-child dyads (child mean age 5 years 4 m…
Adolescent coping and social media use moderated anxiety change during the Covid‐19 pandemic
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
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
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…
Revisiting Jerome Kagan and his research legacy
This special issue of Developmental Psychology is dedicated to the legacy of Jerome Kagan, whose pioneering work profoundly shaped the field of developmental psychology. Kagan's groundbreaking research on temperament, emotional development, and the role of biology in shaping human behavior provided a foundation for understanding individual differences across the lifespan. The 20 articles featured in this issue reflect the breadth and depth of Kag…
Categorical and latent profile approaches to temperamental infant reactivity and early trajectories of socioemotional adjustment
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 trajectories of behavioral inhibition from infancy to age seven
The present study leveraged data from a longitudinal adoption study of 361 families recruited between 2003 and 2010 in the United States. We investigated how psychopathology symptoms in birth parents (BP; M age = 24.1 years; 50.5–62.9% completed high school) and adoptive parents (AP; M age = 37.8 years; 80.9% completed college; 94% mother–father couples) influenced children's behavioral inhibition (BI) trajectories. We used latent growth models o…
The impact of Covid‐19 on infant development
Assessing bidirectional relations between infant temperamental negative affect, maternal anxiety symptoms and infant affect-biased attention across the first 24-months of life
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…
Implementation of the diffusion model on dot-probe task performance in children with behavioral inhibition
Developmental patterns of affective attention across the first 2 years of life
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…
Understanding how child temperament, negative parenting, and dyadic parent–child behavioral variability interact to influence externalizing problems
To better understand the development of externalizing behavior, the current study examines how multiple levels of influence (child temperament, negative parenting, and dyadic interactions) work together to increase externalizing behaviors over time. Negative parenting (NP) and observed dynamic dyadic behavioral variability (DBV) in parent-child interactions (e.g., in discipline and compliance) are characteristic of coercive family processes. The …
Relations between social attention, expressed positive affect and behavioral inhibition during play
Flexible social attention, including visually attending to social interaction partners, coupled with positive affect may facilitate adaptive social functioning. However, most research assessing social attention relies on static computer-based paradigms, overlooking the dynamics of social interactions and limiting understanding of individual differences in the deployment of naturalistic attention. The current study used mobile eye-tracking to exam…
The relation between early behavioural inhibition and later social anxiety, independent of attentional biases to threat
Early behavioural inhibition, a temperamental characteristic defined by fearful, overly-sensitive, avoidant, or withdrawn reactions to the unknown, is a predictor of later social anxiety. However, not all behaviourally inhibited children develop anxiety problems, and attentional bias to threat has been proposed to moderate the relation between behavioural inhibition and anxiety. The current study aimed to further specify the relation between earl…
Individual dynamics of delta–beta coupling
BACKGROUND: Variation in EEG-derived delta-beta coupling has recently emerged as a potential neural marker of emotion regulation, providing a novel and noninvasive method for assessing a risk factor for anxiety. However, our understanding of delta-beta coupling has been limited to group-level comparisons, which provide limited information about an individual's neural dynamics. METHODS: The present study used multilevel modeling to map second-by-s…
Dopaminergic associations between behavioral inhibition, executive functioning, and anxiety in development
Study Protocol
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…
Sharing in the Family System
SYNOPSISObjective. The current study examines whether associations between mothers’ and fathers’ emotional expressiveness and children’s observed sharing behavior differ for two young children in the same family and whether children’s baseline respiratory sinus arrhythmia (RSA) moderates relations between emotional expressiveness and sharing. Design. Altogether 69 families, including mothers, fathers, older siblings (Mage = 57.52 months), and you…
Individual differences in infancy research
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
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…
Patterns of sustained attention in infancy shape the developmental trajectory of social behavior from toddlerhood through adolescence
The current study examined the relations between individual differences in sustained attention in infancy, the temperamental trait behavioral inhibition in childhood, and social behavior in adolescence. The authors assessed 9-month-old infants using an interrupted-stimulus attention paradigm. Behavioral inhibition was subsequently assessed in the laboratory at 14 months, 24 months, 4 years, and 7 years. At age 14 years, adolescents acted out soci…
A Methodological Case Study with Mobile Eye-Tracking of Child Interaction in a Science Museum
The impact of negative affect on attention patterns to threat across the first 2 years of life
The current study examined the relations between individual differences in attention to emotion faces and temperamental negative affect across the first 2 years of life. Infant studies have noted a normative pattern of preferential attention to salient cues, particularly angry faces. A parallel literature suggests that elevated attention bias to threat is associated with anxiety, particularly if coupled with temperamental risk. Examining the emer…
The role of temperament in somatic complaints among young female adults
We examined a temperament-driven construct in relation to broad patterns of somatic behavior among young females ( N = 215, 18-23 years). A multidimensional construct, socio-affective vigilance (SAV), encompassing affective, behavioral, and cognitive traits, along with sensitivity to sensory stimuli (low threshold), were used as predictors. SAV positively predicted somatic behavior and a low sensory threshold was associated with somatic complaint…
Developmental patterns of anger from infancy to middle childhood predict problem behaviors at age 8
Anger is a central characteristic of negative affect and is relatively stable from infancy onward. Absolute levels of anger typically peak in early childhood and diminish as children become socialized and better able to regulate emotions. From infancy to school age, however, there are also individual differences in rank-order levels of anger. For example, although decreasing in absolute levels, some children may stay the same and others may incre…
Young Children's Affective Responses to Acceptance and Rejection From Peers
This study presents a novel task examining young children's affective responses to evaluative feedback-specifically, social acceptance and rejection-from peers. We aimed to determine (1) whether young children report their affective responses to hypothetical peer evaluation predictably and consistently, and (2) whether young children's responses to peer evaluation vary as a function of temperamental shyness and gender. Four- to seven-year-old chi…
Stable Early Maternal Report of Behavioral Inhibition Predicts Lifetime Social Anxiety Disorder in Adolescence
Impact of Behavioral Inhibition and Parenting Style on Internalizing and Externalizing Problems from Early Childhood through Adolescence
Attention biases to threat and behavioral inhibition in early childhood shape adolescent social withdrawal
Behavioral inhibition (BI) is a temperament characterized in young children by a heightened sensitivity to novelty, social withdrawal, and anxious behaviors. For many children, these social difficulties dissipate over time. For others, patterns of social withdrawal continue into adolescence. Over time, attention biases to threat may influence the stability of BI and its association with social withdrawal, ultimately modulating the risk for anxiet…

Temperament Development, Theories of
Developmental Differences in Infants' Attention to Social and Nonsocial Threats
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…
Maternal anxiety predicts attentional bias towards threat in infancy
Although cognitive theories of psychopathology suggest that attention bias toward threat plays a role in the etiology and maintenance of anxiety, there is relatively little evidence regarding individual differences in the earliest development of attention bias toward threat. The current study examines attention bias toward threat during its potential first emergence by evaluating the relations between attention bias and known risk factors of anxi…
