A BEHAVIORAL MODEL OF INFANT SLEEP DISTURBANCE

Chronic sleep disturbance, such as bed refusal, sleep-onset delay, and night waking with crying, affects 15% to 35% of preschool children. Biological factors, particularly arousals associated with recurrent episodes of rapid-eye-movement sleep, render infants vulnerable to repeated awakenings. Parental failure to establish appropriate stimulus control of sleep-related behaviors and parent-mediated contingencies of reinforcement for sleep-incompatible behaviors may shape and maintain infant sleep disturbance. Treatment and prevention strategies are discussed, and research needs are identified.     

CONTRIBUTORS TO STRESS RESISTANCE

This study integrated work-family research with the stress resource perspective and organizational leadership theory. Based on the premise that stress is a major contributor to work-family conflict, this research examined resources likely to reduce the stress and work-family conflict women experience. Family emotional support, leader-member exchange, and hardiness were explored as potential resources. The 206 participants were recruited in daycare centers, a business community, and a university setting. The sample was diverse in terms of ethnicity and occupation. However, the majority of the women were married (68%) with children (82%). Path analytic tests supported most of the relationships in the hypothesized model. Findings suggest that having a high-quality relationship with one's supervisor may have complex implications for work-family conflict.     

Reading between the minds: the use of stereotypes in empathic accuracy

An ideal empathizer may attend to another person's behavior in order to understand that person, but it is also possible that accurately understanding other people involves top-down strategies. We hypothesized that perceivers draw on stereotypes to infer other people's thoughts and that stereotype use increases perceivers' accuracy. In this study, perceivers (N = 161) inferred the thoughts of multiple targets. Inferences consistent with stereotypes for the targets' group (new mothers) more accurately captured targets' thoughts, particularly when actual thought content was also stereotypic. We also decomposed variance in empathic accuracy into thought, target, and perceiver variance. Although past research has frequently focused on variance between perceivers or targets (which assumes individual differences in the ability to understand other people or be understood, respectively), the current study showed that the most substantial variance was found within targets because of differences among thoughts.     

A Trust-Based Home Intervention for Special-Needs Adopted Children: A Case Study

Research on the effects of abuse, neglect, and other traumas in early childhood has consistently demonstrated severe deficits that can be prevalent across the life span. Costs associated with addressing such deficits in special-needs children can strain families and are an immense financial burden to society. Trust-Based Relational Intervention® is an intervention modality that targets the attachment system as part of a dynamic system of development. Presented is a summary of the costs of addressing the sequelae of childhood abuse and neglect, a brief overview of Trust-Based Relational Intervention, and a case study demonstrating the efficacy of this intervention with an adopted special-needs child in a home-based setting.     

Perceptions of Younger Single Adults as a Function of Their Gender and Number of Children

ABSTRACT. Research suggests that children may interfere with single parents’ romantic experiences. Although both male and female single parents face these challenges, they have stronger associations with the romantic satisfaction of single mothers as compared to single fathers. The two current studies examined aspects of attractiveness and dating across various dimensions for both younger single women and men, with and without children. Results of Study 1 indicated interactive effects of target gender and parental status on perceptions of both attractiveness and dating potential. Results of Study 2 indicated differential ratings on multiple dimensions (i.e., attractiveness, stress, motivation for dating, and positive qualities) of younger single adults on the basis of gender, parental status, and the number of children single parents were reported as having. Implications for importance of social support and difficulty of repartnering are discussed.     

Facilitation of Extinction of Conditioned Fear by D-Cycloserine

Abstract— Excessive fear and anxiety are characteristic of disorders such as post-traumatic stress disorder (PTSD) and phobias and are believed to reflect abnormalities in neural systems governing the development and reduction of conditioned fear. Conditioned fear can be suppressed through a process known as extinction, in which repeated exposure to a feared stimulus in the absence of an aversive event leads to a gradual reduction in the fear response to that stimulus. Like conditioned fear learning, extinction is dependent on a particular protein (the N-methyl-D-aspartate or NMDA receptor) in a part of the brain called the amygdala. Blockade of this receptor blocks extinction and improving the activity of this receptor with a drug called D-cycloserine speeds up extinction in rats. Because exposure-based psychotherapy for fear disorders in humans resembles extinction in several respects, we investigated whether D-cycloserine might facilitate the loss of fear in human patients. Consistent with findings from the animal laboratory, patients receiving D-cycloserine benefited more from exposure-based psychotherapy than did placebo-treated controls. Although very preliminary, these data provide initial support for the use of cognitive enhancers in psychotherapy and demonstrate that preclinical studies in rodents can have direct benefits to humans.     

Treating sleep disturbance in infants: What generalizes?

When treating infant sleep problems implementing treatment procedures at bedtime‐only might be easier and more efficient than requiring parents to implement procedures throughout the night, but only if improvements at bedtime generalize to later in the night. This study investigated the immediate and generalized effect of treating bedtime settling problems and later night waking in infants and whether it was parent or child behavior that generalized. Parents recorded sleep problems of seven infants (6–20 months) who exhibited chronic sleep disturbance, then implemented a graduated checking procedure at bedtime‐only (Setting 1). A multiple‐baseline across‐settings and participants design was employed. Immediate (in Setting 1) and any generalized effects (in Setting 2) on wakings and other changes in parent and child behavior were assessed by diary information and all‐night infra‐red video recordings. Clinically significant reductions in sleep problems were evident for five out of seven infants, but these were not consistently observed until parents generalized their use of the procedure throughout the night. There was no evidence that the infants generalized changes in self‐soothing from bedtime to later. It is concluded that changes in infant sleep problems are unlikely to occur unless parents actually alter their management of the problems across all settings in which the problems occur.
