Anxiogenic Patterns in Mother-Child Interactions

ABSTRACT

The current study examined psychosocial variables associated with the development of anxiety in children. While previous literature has established parental affectionless control as an important contributor to the development of anxiety in children, few have examined this construct within the dynamic context of parent-child interaction. In the current study, the affect and behavior of anxious mothers and their children (ages 6 to 12 years) were examined during two mildly stressful tasks, with a total of 64 mother-child dyads participating in the study. Analyses supported the hypothesis that maternal affectionless control mediates the relationship between child anxiety and child disengagement/withdrawal from difficult tasks. Results are discussed in terms of implications for psychosocial mechanisms of the familial transmission of anxiety.     

Punishing and atoning: a new critique of penal substitution

The doctrine of penal substitution claims that it was good (or required) for God to punish in response to human sin, and that Christ received this punishment in our stead. I argue that this doctrine’s central factual claim—that Christ was punished by God—is mistaken. In order to punish someone, one must at least believe the recipient is responsible for an offense. But God surely did not believe the innocent Christ was responsible for an offense, let alone the offense of human sin. So, the central factual claim is mistaken. In the final section, I show that this critique of penal substitution does not apply to the closely-related Anselmian satisfaction theory.     

The role of the self‐fulfilling prophecy in young adolescents' responsiveness to a substance use prevention program

This research examined whether naturally occurring self‐fulfilling prophecies influenced adolescents' responsiveness to a substance use prevention program. The authors addressed this issue with a unique methodological approach that was designed to enhance the internal validity of research on naturally occurring self‐fulfilling prophecies by experimentally controlling for prediction without influence. Participants were 321 families who were assigned to an adolescent substance use prevention program that either did or did not systematically involve parents. Results showed that parents' perceptions about the value of involving parents in adolescent substance use prevention predicted adolescents' alcohol use more strongly among families assigned to the prevention program that systematically involved parents than to the one that did not. The theoretical and practical implications of these findings are discussed.     

The Effect of Knee Joint Angle on Torque Control

The purpose of the author's investigation was to examine the effect of knee joint angle on torque control of the quadriceps muscle group. In all, 12 healthy adults produced maximal voluntary contractions and submaximal torque (15, 30, and 45% MVC [maximal voluntary contraction]) at leg flexion angles of 15°, 30°, 60°, and 90° below the horizontal plane. As expected, MVC values changed with respect to joint angle with maximum torque output being greatest at 60° and least at 15°. During the submaximal tasks, participants appropriately scaled their torque output to the required targets. Absolute variability (i.e., standard deviation) of torque output was greatest at 60° and 90° knee flexion. However, relative variability as indexed by coefficient of variation (CV) decreased as joint angle increased, with the greatest CV occurring at 15°. These results are congruent with the hypothesis that joint angle influences the control of torque.     

My people,right or wrong? Minimal group membership disrupts preschoolers’ selective trust

When preschoolers decide to trust one speaker over another, how does group membership influence their tracking of speaker reliability? In Experiment 1, 4-year-olds were assigned to arbitrary groups of no social significance (0055 and 0170) and asked to endorse novel object labels provided by two ingroup members, one of whom was reliable and the second of whom was unreliable. Children selectively trusted the more reliable informant. In Experiment 2, we asked whether ingroup status or reliability would determine children's choices and found that 4-year-olds failed to trust reliable outgroup members over unreliable ingroup members (or vice versa). Experiment 3 showed that the failure of trust in Experiment 2 was not due to the mere inclusion of both ingroup and outgroup members: children presented with a control paradigm in which the ingroup members were reliable trusted reliable ingroup members over unreliable outgroup members. Children's use of reliability as an indicator of future credibility therefore appears disrupted when outgroup status and reliability are in conflict, even when group membership is arbitrary.     

The Relationship Between Postdeployment Factors and PTSD Severity in Recent Combat Veterans

Combat traumas precipitate posttraumatic stress disorder (PTSD); however, nontraumatic deployment and postdeployment factors may also contribute to PTSD severity. The Deployment Risk and Resilience Inventory (DRRI) was used to investigate pre-, peri-, and postdeployment factors associated with current PTSD severity in 150 recent combat veterans with PTSD and hazardous alcohol use. Hierarchal linear regression analyzed what factors independently predicted PTSD severity when controlling for sociodemographic characteristics and combat specific variables. Four postdeployment factors independently predicted PTSD severity: unemployment, alcohol use, social support, and stressful (nontraumatic) life events. The centrality of trauma in the maintenance of PTSD and clinical implications for treatment providers are discussed.     

Clarifying the Linguistic Signature: Measuring Personality From Natural Speech

In this study, we examined the viability of measuring personality using computerized lexical analysis of natural speech. Two well-validated models of personality were measured, one involving trait positive affectivity (PA) and negative affectivity (NA) dimensions and the other involving a separate behavioral inhibition motivational system (BIS) and a behavioral activation motivational system (BAS). Individuals with high levels of trait PA and sensitive BAS expressed high levels of positive emotion in their natural speech, whereas individuals with high levels of trait NA and sensitive BIS tended to express high levels of negative emotion. The personality variables accounted for almost a quarter of the variance in emotional expressivity.     

Competence and Trust in Choice Architecture

Richard Thaler and Cass Sunstein’s Nudge advances a theory of how designers can improve decision-making in various situations where people have to make choices. We claim that the moral acceptability of nudges hinges in part on whether they can provide an account of the competence required to offer nudges, an account that would serve to warrant our general trust in choice architects. What needs to be considered, on a methodological level, is whether they have clarified the competence required for choice architects to prompt subtly our behaviour toward making choices that are in our best interest from our own perspectives. We argue that, among other features, an account of the competence required to offer nudges would have to clarify why it is reasonable to expect that choice architects can understand the constraints imposed by semantic variance. Semantic variance refers to the diverse perceptions of meaning, tied to differences in identity and context, that influence how users interpret nudges. We conclude by suggesting that choice architects can grasp semantic variance if Thaler and Sunstein’s approach to design is compatible with insights about meaning expressed in science and technology studies and the philosophy of technology.     

Early Institutionalization: Neurobiological Consequences and Genetic Modifiers

Children raised in the profound deprivation associated with institutionalization are at elevated risk for negative outcomes across a host of social and cognitive domains. This risk appears to be mitigated by early foster care or adoption into a family setting. Although pervasive developmental problems have been noted in a substantial proportion of previously institutionalized children, marked variation exists in the nature and severity of these deficits. Increasing evidence suggests that institutional deprivation impacts the developing brain, potentially underlying the wide range of outcomes with which it is associated. In the current review we examine the neural consequences of institutionalization and genetic factors associated with differences in outcome in an effort to characterize the consequences of early deprivation at a neurobiological level. Although the effects of institutional deprivation have been studied for more than 50 years much remains unanswered regarding the pathways through which institutionalization impacts child development. Through a more complete and nuanced assessment of the neural correlates of exposure and recovery as well as a better understanding of the individual factors involved we will be better able to delineate the impact of early adversity in the setting of severe social deprivation.     

Better working memory for non-social targets in infant siblings of children with Autism Spectrum Disorder

We compared working memory (WM) for the location of social versus non-social targets in infant siblings of children with Autism Spectrum Disorders (sibs-ASD, n  =   25) and of typically developing children (sibs-TD, n  =   30) at 6.5 and 9 months of age. There was a significant interaction of risk group and target type on WM, in which the sibs-ASD had better WM for non-social targets as compared with controls. There was no group by stimulus interaction on two non-memory measures. The results suggest that the increased competency of sibs-ASD in WM (creating, updating and using transient representations) for non-social stimuli distinguishes them from sibs-TD by 9 months of age. This early emerging strength is discussed as a developmental pathway that may have implications for social attention and learning in children at risk for ASD.
