The secure base phenomenon was ascribed to changes in exploration observed during Ainsworth's Strange Situation Procedure (SSP), related to the quality of the attachment relationship. However, infant temperament was not taken into consideration. The current study aims to replicate Ainsworth's findings regarding infant exploration and attachment…

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…

As availability of parent-child interaction curricula increases, Early Head Start (EHS) provides a relevant context to test research-based parenting models as part of everyday practice. We trained EHS staff to incorporate the Promoting First Relationships (PFR) intervention into ongoing weekly home visits with mothers and their young children (n =…

Several researchers have found that media exposure through books or electronic media contribute to preschoolers' development. However, research with behavioral measures and during the first years of life have not been carried out in Latin American contexts. The aim of the following research was to evaluate the relations between media exposure…

Questions concerning longitudinal stability and multi-method consistency are critical to temperament research. Latent State-Trait (LST) analyses address these directly, and were utilized in this study. Thus, our primary objective was to apply LST analyses in a temperament context, using longitudinal and multi-method data to determine the amount of…

Research Findings: This study considered the interplay between infant temperament and maternal caregiving behaviors in relation to early language. A total of 118 mother-infant dyads participated in the study. Mothers rated infant positive affect (PA) and negative affect (NA), and maternal behaviors were coded during a free-play task when infants…

Emotion regulation is essential to cognitive, social, and emotional development and difficulties with emotion regulation portend future socioemotional, academic, and behavioral difficulties. There is growing awareness that many developmental outcomes previously thought to begin their development in the postnatal period have their origins in the…

The paper reports on a study which tested whether infants high in negative affectivity are differentially susceptible to observed coparenting behavior in relation to their subsequent social-emotional development. Data came from a longitudinal study of 182 US dual-earner, primiparous couples and their infant children. At nine-months postpartum,…

This research examined the child, parent, and family conditions under which attachment disorganization was related to both level and change in externalizing behavior during preschool among a community sample. Using the ordinary least squares regression, we found that attachment disorganization at 12 months significantly predicted children's…

This study investigated the normative use and developmental course of physical aggression (PA), defined as use of physical force such as hitting, biting, and kicking, from 8 to 26 months and predictors thereof. We used data from the Behavior Outlook Norwegian Developmental Study, comprising 1,159 children (559 girls and 600 boys). Both mothers and…

In this longitudinal study, 83 parents of infants between 3 and 12 months completed questionnaires assessing demographic information, infant temperament, and maternal depression. When these children were at least 18 months of age, parents completed follow-up questionnaires assessing toddler temperament and depression-like symptoms. We were…

Predictors of prenatal and postnatal parenting efficacy were examined in a sample of 115 primiparous mothers and 73 fathers in an effort to examine the association between preexisting parental characteristics and prenatal efficacy and the association between prenatal characteristics and postnatal efficacy when aspects of the current parenting…

This longitudinal study examined the extent to which dimensions of infant negative temperament in the first year predicted IQ at age 3, and whether these associations depended on the quality of the infant-mother attachment relationship. In a sample of 63 infant-mother dyads, mothers completed Rothbart's (1981) IBQ when infants were 4 and 12…
