The effects of children’s proximity‐seeking to maternal attachment figures during mild stress exposure on mood and physiological responses: An experimental study

Negative mood induction in children: An examination across mood, physiological, and cognitive variables

Experimental mood induction procedures are commonly used in studies of children's emotions, although research on their effectiveness is lacking. Studies that support their effectiveness report sample-level changes in self-reported affect from pre- to post-induction, and a subset of children who do not self-report expected changes in affect (i.e., "nonresponders"). Given children's limited abilities to self-report their emotions, it is critical to know whether these paradigms also shift physiological and social-cognitive indices of emotion. We hypothesized increases in physiological reactivity and accuracy for discerning facial expressions of negative emotions from pre- to post-induction and smaller increases for nonresponders, Children (N = 80; 7- to 12-year-olds) completed a facial emotion recognition task and had an electrocardiogram recorded to index high-frequency heart rate variability (HF-HRV) before and after a mood induction procedure. The mood induction involved watching a 3-min sad film clip while attending to their feelings. In the sample overall, from pre- to post-mood induction, children self-reported significantly sadder affect, displayed significant increases in HF-HRV, and displayed significant increases in accuracy of recognizing facial emotion expressions congruent with the mood induced. One quarter (25%) of the sample did not self-report expected increases in sad affect. Contrary to expectations, responders and nonresponders did not differ in mood-induced changes in physiological reactivity or emotion recognition accuracy. These findings support that mood inductions are efficacious in shifting not only children's self-reported affect but also underlying physiological and social-cognitive processes. Furthermore, they are an effective methodology for research questions related to underlying processes even in self-reported nonresponders.

Multisystem physiological reactivity during help-seeking for attachment needs in school-aged children: differences as a function of attachment

In this study, we sought to expand on what is currently known regarding autonomic nervous system (ANS) reactivity in middle childhood as a function of attachment. ANS activity includes multiple indices - respiratory sinus arrhythmia (RSA) is an index of parasympathetic nervous system activation (PNS) and electrodermal activity (EDA) is an index of sympathetic nervous system activation (SNS). Children (N = 103) completed Child Attachment Interviews and read vignettes describing situations aimed to activate attachment needs (NEED; e.g., getting hurt, which can elicit need for comfort or assistance) and help-seeking (HS; when children experience need and seek comfort from attachment figures), while SNS and PNS reactivity were monitored. Attachment was not associated with children's SNS or PNS reactivity during NEED, but attachment was associated with physiological reactivity during HS: Dismissing attachment was associated with greater SNS activation (higher EDA) and preoccupied attachment with PNS deactivation (lower RSA, greater vagal withdrawal) during HS.

Parent–Child Attachment and Dynamic Emotion Regulation: A Systematic Review

Although there is evidence parent–child attachment security is associated with trait-like emotion indices, trait perspectives do not fully capture children's responses to context, an important emotion regulation component. This paper evaluates whether attachment is associated with two dynamic emotion indicators: emotion reactivity and emotion recovery. We review conceptual and empirical connections, describe the dynamic emotion perspective, discuss hypotheses, and review evidence. Our review (15 studies) shows that secure attachment was more consistently related to recovery than reactivity, avoidant attachment was related to low emotion reactivity and recovery, ambivalent attachment was associated with greater emotion reactivity, and disorganized attachment was related to high reactivity and recovery difficulties. We close by comparing trait-like and dynamic emotion conclusions then propose future research directions.

A Learning Theory Approach to Attachment Theory: Exploring Clinical Applications

Although clinicians typically acknowledge the importance of insecure attachment as one factor that can contribute to children's psychopathology, translating attachment theory into clinical practice has proved a challenge. By specifying some of the mechanisms through which the child's attachment develops and changes, learning theory can enhance attachment based approaches to therapy. Specifically, interventions building on operant (parent management training) and classical (exposure therapy) learning can be used to stimulate new learning that increases the child's security and confidence in the parent's availability and responsiveness. To explore the clinical application and utility of a Learning Theory of Attachment (LTA), we focus on two attachment-focused interventions: Video-feedback Intervention to promote Positive Parenting and Sensitive Discipline (VIPP-SD) and Middle Childhood Attachment-based Family Therapy (MCAT). VIPP-SD is an evidence-based parent management training designed to promote sensitive parenting and secure attachment in early childhood. MCAT is a recently developed intervention that uses exposure to stimulate secure attachment in middle childhood. LTA sheds light on the mechanisms set in train by VIPP-SD and MCAT facilitating the induction of professionals in clinical applications.

Charting the physiological time course of help-seeking during late childhood: Patterns of individual difference

In this study, we explored whether variability in children's physiological reactivity-respiratory sinus arrhythmia and electrodermal activity-predict concurrent and subsequent levels of children's observed help-seeking (HS) from their mothers during a failure task. In addition, we tested whether children's perceptions of maternal positivity pre-task (CPMP) and children's fearful temperament moderate these effects. In a community sample of 101 mother-child dyads, children (8-12 years of age) underwent a repeated failure task while their respiratory sinus arrythmia and electrodermal activity were monitored; their HS behaviors were later coded. Multilevel path analyses indicated that high-fearful children increased their HS at the same time as and following increased physiological reactivity regardless of CPMP pre-task. Low-fearful children showed increases in HS at the same time as and following increased physiological reactivity only when they perceived their mothers' affect to be positive. This study demonstrates children's individual differences in the physiological underpinning of time-linked HS behaviors.

A learning theory of attachment: Unraveling the black box of attachment development

Attachment is an inborn behavioral system that is biologically driven and essential for survival. During child development, individual differences in (in)secure attachment emerge. The development of different attachment behaviors has been traditionally explained as a process during which experiences with (lack of) responsive and supportive care are internalized into working models of attachment. However, this idea has been criticized for being vague and even untestable. With the aim of unraveling this black box, we propose to integrate evidence from conditioning research with attachment theory to formulate a Learning Theory of Attachment. In this review, we explain how the development of individual differences in attachment security at least partly follows the principles of classical and operant conditioning. We combine observed associations between attachment and neurocognitive and endocrinological (cortisol, oxytocin, and dopamine) processes with insights in conditioning dynamics to explain the development of attachment. This may contribute to the explanation of empirical observations in attachment research that are insufficiently accounted for by traditional attachment theory.
