Meta-Analyses of the Associations Between Disinhibited Social Engagement Behaviors and Child Attachment Insecurity or Disorganization

Children with disinhibited social engagement disorder show reduced reticence with strangers, do not check back with their caregiver after venturing away, and may willingly leave with an unfamiliar adult. The recent DSM-5 has moved away from an attachment framework to understand disinhibited social engagement behavior (DSEB) due to studies indicating its presence in previously institutionalized children even after these children are adopted and show a selective, more secure attachment with their substitute caregiver (e.g. Chisholm et al., 1998). This meta-analysis aims to clarify the size of the associations between DSEB and attachment insecurity or disorganization. It also examines whether studies effect sizes differ according to various moderators (e.g., child age, type of attachment and DSEB measures). The results (k?=?24) showed that the associations between DSEB and attachment insecurity (d?=?0.48) or attachment disorganization (d?=?0.47) were of small magnitude. There were no publication biases. As for moderator analyses on both attachment insecurity and disorganization, the effect sizes in studies using DSEB observational measures (respectively d?=?0.63 and 0.57) were of moderate magnitude and stronger than those in studies not using an observational component (respectively d?=?0.28 and 0.32). Given these small-to-moderate associations, attachment can be considered a relationship process associated with DSEB, and attachment-informed interventions could be potential tools to reduce DSEB in children. Nevertheless, given the sizable unshared portion of variance between DSEB and child attachment, future studies should examine other variables related to caregiving and noncaregiving contexts to further understand DSEB.

     

Stability of attachment during the preschool period

Children's attachment patterns at early preschool age and 2 years later as well as factors related to stability-instability were examined in a diverse socioeconomic status French Canadian sample of 120 children. Attachment was assessed during 2 laboratory visits using separation-reunion procedures when the children were approximately 3.5 (J. Cassidy & R. S. Marvin, 1992) and 5.5 (M. Main & J. Cassidy, 1988) years old. Overall, stability of attachment, based on 4-way classification, was moderate (68%, k = .47, p = .01). Change from security to disorganization was associated with the most dramatic decline in interactive quality with mother, lowest marital satisfaction, and greatest likelihood of severe attachment-related family events, namely, loss and parental hospitalization. Families of children who changed from security to organized insecurity presented levels of caregiving and marital dissatisfaction that fell between those of stable secure children and secure children who changed toward disorganization.     

Adaptation of Neuromuscular Synergies During Intentional Constraints of Space-Time Relationships in Human Gait

Tight frequency-to-amplitude relationships are observed in spontaneous human steady gait. They can be modified, if required; that flexibility forms a fundamental basis of the intentional adaptive capabilities of locomotion. In the present experiments, the processes underlying that flexibility were investigated at both the level of joint kinematics and the level of neuromuscular synergies. Subjects (N = 4) walked at the same speed either with a preferred or a nonpreferred frequency-to-amplitude relationship (i.e., constrained, short steps at a high frequency [COS condition] or constrained, long steps at a low frequency [COL condition]); their swing and stance phases were separately analyzed. In the COS condition, increases in EMG activity were specifically required during the swing phase. In the COL condition, several muscles required increases in EMG activity during the stance phase, but decreases of the hamstring muscles were needed during the swing phase. Whereas, in preferred walking, modification of the frequency affects the EMG patterns globally (the gain increasing with the frequency in both the stance and swing phases), the present results show that changing the frequency in a constrained manner either affects the swing phase specifically or affects both phases, but in the opposite direction. That finding indicates mat a separate control is needed in both the swing and the stance phases.     

What’s ours is yours: recall of history for lesser-known countries is guided by one’s own national history

ABSTRACT

The present studies examine how people recall history. Sometimes, certain national histories are well known and sometimes they are not. We propose that, under certain circumstances, culturally distinctive representations of typical national histories can be used to guide recall, particularly in cases where the history is not well known. We focus on three national samples with varied levels of knowledge about each history: Great Britain, India, and the United States. In Study 1, we establish typical historical event templates for each nation consisting of events that a large proportion of participants from each sample identify as important in a typical nation’s history. We examine points of divergence between the different groups’ typical event templates and the valences of these events. In Study 2, we test and find that, in conditions of less knowledge, participants tend to refer to particular historical events that coincide with events unique to their own group’s typical history. In Study 3, we demonstrate that this effect can be found even when a group possesses a reasonable amount of knowledge about the target country. We conclude by discussing the implications in relation to how such a retrieval strategy might inform interpretations of events in the present.

Transfer of Skills in the Context of Non‐Suggestive Investigative Interviews: Impact of Structured Interview Protocol and Feedback

Two groups of police investigators were trained in the use of the National Institute of Child Health and Human Development (NICHD) interview protocol. After the training, one group (n = 8) received written feedback on each interview they conducted, whereas the other group (n = 11) did not. The objective of the study was, first, to evaluate the effect of NICHD protocol implementation on the types of questions and details provided by children and, second, to evaluate the impact of post‐training feedback. Interviewees were alleged sexual abuse victims between the ages of 3 and 14 years. Application of the NICHD protocol allowed interviewers to use more open‐ended questions and to obtain more details. The results show that providing feedback significantly increased the quality of the interviews. It is recommended that the NICHD protocol be used to interview child victims and witnesses and that feedback sessions be held with interviewers. Copyright © 2012 John Wiley & Sons, Ltd.
