Longitudinal Impact of Toddlers' Exposure to Domestic Violence

This study assessed how exposure to domestic violence (DV) during early childhood and increases in exposure over time influenced toddlers' behavior and peer problems, physical health, and cognitive abilities in middle childhood. Data from three waves of the survey component of “Welfare, Children, and Families: A Three-City Study” were assessed. Thirty-five percent of the 2- to 4-year-olds had mothers who reported DV victimization; 16% reported an increase in DV victimization over 2 years. Opposing past literature, none of the middle childhood outcomes were significantly influenced by early DV exposure. However, increases in mother's DV victimization from 1999 to 2001 significantly increased children's internalizing and externalizing problems and marginally decreased their school engagement in middle childhood in 2005.     

“Playing by the Book”: Determinants of Children's Preference for Replicating and Originating Play

Play is children's most important daily behavior and when children play, they do so in multiple ways. With two studies, this paper explores how children perceive a continuum of two play types, namely replicating play (in which models, guidelines, and examples are used to reach an intended result) and originating play (in which children create something from the mind, think freely about how they will play, are less restricted by given models, etc.). Study 1 (N = 56, M_age = 9) quantitatively shows that both play types occur and tests if children also describe the play types as we define them. Results show that children who play originating (vs. replicating) believe they follow less (vs. more) rules and do their own thing more (vs. less), which verifies the definitions of both types of play. Study 2 includes 16 in-depth semi-structured interviews (M_age = 10) and shows which determinants children identify as triggers for engaging in play that has more replicating or more originating elements.     

Motor Imitation in Young Children with Autism: What's the Object?

Two studies investigated the nature of motor imitation in young children with autism. Study 1 compared different types of motor imitation in 18 autistic children, 18 children with developmental delay, and 18 normally developing children. Results revealed weaker imitation skills for the autistic group, though all groups demonstrated a similar pattern of performance across different imitation domains. Imitation of body movements was more difficult than imitation of actions with objects, and imitation of nonmeaningful actions was more difficult than imitation of meaningful actions. Study 2 investigated concurrent and predictive relations between imitation and other developmental skills within a sample of 26 two-year-old children with autism. Results suggested that imitation of body movements and imitation of actions with objects represent independent dimensions. Imitation of body movements was concurrently and predictively associated with expressive language skills, and imitation of actions with objects was concurrently associated with play skills. Improvements in both motor imitation domains occurred over a 1-year period.     

A Review of “Mind to Mind: Infant Research,Neuroscience, and Psychoanalysis”

Abstract

This article examines current research pertaining to the relationship between a mother and her children, and how this relationship may affect sibling interactions. Issues such as temperament, gender, and the age gap between children are also explored to ascertain their impact on the sibling relationship.

The displacement of the first-born child and the ensuing sense of loss and anger he may experience as a result of this is explored. The mother's second pregnancy is also discussed in regard to the impact of unresolved issues relating to her own sibling relations. The mother's interactions with each child, her role as a model for identification, and marital relations are discussed in light of their impact on sibling relations.

The evolution of a positive attachment between siblings is explored. Rivalrous behavior between siblings is also discussed, particularly in association to the mother's treatment of her own children and the manner in which the mother deals with her own aggression.     

GENERALIZED IMITATION AND RESPONSE-CLASS FORMATION IN CHILDREN WITH AUTISM

An experimental analysis of imitation was conducted to examine the influence of response topography on generalization of imitation across three response types. Four children with autism were presented with both reinforced training trials and nonreinforced probe trials of models from vocal, toy-play, and pantomime response types. The probe trials were used to examine generalization within each response type. A multiple baseline design was used to analyze percentage of matching and nonmatching responses to models across response types. This study, the first to analyze imitative response classes in children with autism, showed that imitation generalized from reinforced training models to nonreinforced probe models within a response type, but it did not generalize across response types. Thus, functional response classes determined by topographical boundaries were exhibited within generalized imitation.     

The Early Childhood Irritability-Related Impairment Interview (E-CRI): A Novel Method for Assessing Young Children’s Developmentally Impairing Irritability

Irritability is a substrate of more than one dozen clinical syndromes. Thus, identifying when it is atypical and interfering with functioning is crucial to the prevention of mental disorder in the earliest phase of the clinical sequence. Advances in developmentally based measurement of irritability have enabled differentiation of normative irritable mood and tantrums from indicators of concern, beginning in infancy. However, developmentally sensitive assessments of irritability-related impairment are lacking. We introduce the Early Childhood Irritability-Related Impairment Interview (E-CRI), which assesses impairment associated with irritable mood and tantrums across contexts. Reliability and validity are established across two independent samples varied by developmental period: the Emotional Growth preschool sample (EmoGrow; N = 151, M = 4.82 years) and the When to Worry infant/toddler sample (W2W; N = 330, M = 14 months). We generated a well-fitting two-factor E-CRI model, with tantrum- and irritable mood-related impairment factors. The E-CRI exhibited good interrater, test–retest, and longitudinal reliability. Construct and clinical validity were also demonstrated. In both samples, E-CRI factors showed association to internalizing and externalizing problems, and to caregiver-reported concern in W2W. Tantrum-related impairment demonstrated stronger and more consistent explanatory value across outcomes, while mood-related impairment added explanatory utility for internalizing problems. The E-CRI also showed incremental utility beyond variance explained by the Family Life Impairment Scale (FLIS) survey indicator of developmental impairment. The E-CRI holds promise as an indicator of impairment to inform identification of typical versus atypical patterns reflecting early emerging irritability-related syndromes in the initial phase of the clinical sequence.
