Here we advance the proposal that in addition to the importance of emotion words, the dynamics of allostatic regulation play a central role in emotion concept development. We argue for a comprehensive extension of constructed emotion theory to emotional development. To do so, we emphasize possible mechanisms for emotion concept differentiation…

In this commentary on the special issue on emotional development, I focus on the papers by Holodynski and Seeger (2019) and by Hoemann, Xu, and Barrett (2019). I suggest that although understanding our emotions is an important part of emotional development; emotional development cannot be reduced to concept development, even when such concepts…

Change is the sine qua non of emotion regulation (ER) and, thus, to understand ER we must analyze its temporal dynamics. Articles in the ER section of this special issue provide strong empirical evidence for the centrality of temporal dynamics in the development of ER on 3 levels: Rapid changes in spatial and temporal dynamics across multimodal…

In this commentary, I delineate several questions raised by the Hammond and Drummond (2019) paper: (a) to why there seems to be an association between state positive emotion and prosocial behavior in young children, and if and how early positively tinged prosocial behavior provides a pathway to (b) later prosocial behavior more generally…

Emotions form the foundation of infants' early social interactions and yet their role in prosocial behaviors is generally limited to situations of distress and other negative emotions. The present article argues that both positive emotions and the emotion of interest play important roles in prosocial behavior and development. First, we explore the…

In this article, we integrate two constructionist approaches--the theory of constructed emotion and rational constructivism--to introduce several novel hypotheses for understanding emotional development. We first discuss the hypothesis that emotion categories are abstract and conceptual, whose instances share a goal-based function in a particular…

I argue that emotion research needs formal (mathematical) theory to address two central questions. How does evolution shape mechanisms of emotion development across generations, depending on environmental conditions? How do these mechanisms generate emotions, based on lifetime experience and current context? Formal modeling enables researchers to…

Although there are frequent calls for the study of effects of children on families and mutual influence processes within families, little empirical progress has been made. We address these questions at the level of microprocesses during marital conflict, including children's influence on marital conflict and parents' influence on each other.…

Two goals guided this study: (a) describe changes in infant fear and anger reactivity from 4 to 16 months and (b) examine the degree to which infant temperament, attentional regulation, and maternal sensitivity predict reactivity trajectories. Participants included 143 mothers and infants (57% male) who visited the laboratory at 4, 8, 12, and 16…

Some children show emotion that is not consistent with normative appraisal of the context and can therefore be defined as context inappropriate (CI). The authors used individual growth curve modeling and hierarchical multiple regression analyses to examine whether CI anger predicts differences in hypothalamic-pituitary-adrenal axis activity, as…

Multiple methods were used to examine children's awareness of connections between emotion and prayer. Four-, 6-, and 8-year-olds and adults (N = 100) predicted whether people would pray when feeling different emotions, explained why characters in different situations decided to pray, and predicted whether characters' emotions would change after…

Extensive research has linked a greater female tendency to ruminate about depressed feelings or mood to the gender difference in depression. However, the developmental origins of the gender difference in depressive rumination are not well understood. We hypothesized that girls and women may be more likely to ruminate because rumination represents…

Four studies were conducted on the development and validation of the Measure of Sexual Identity Exploration and Commitment (MoSIEC). Exploratory factor analysis of an initial item pool yielded a 22-item measure with 4 distinct factors assessing commitment, exploration, sexual orientation identity uncertainty, and synthesis/integration. Exploratory…

In a sample of 7,695 families in the prospective, nationally representative British Millennium Cohort Study, this study examined whether characteristics of the 1st-born child predicted parents' timing and probability of having another child within 5 years after the 1st child's birth. Infant temperament was assessed with the Carey Infant…

The purpose of this study was to test the hypothesis that children's hostile attributions and behavioral strategies in response to peer provocation and rebuff situations will depend on the relationship with the target peer (i.e., friend, enemy, neutral). The sample consisted of 144 fourth graders (75 boys and 69 girls; mean age=10.47 years,…
