Teacher–child conflict and aggressive behaviour in first grade: the intervening role of children's self‐esteem

High levels of teacher–child conflict have repeatedly been found to amplify children's aggressive behaviour. Up to now, however, research on possible mechanisms explaining this link is largely lacking. The current study aimed to test whether children's self‐esteem is an intervening mechanism. Participants were 139 children (70 boys, M age = 6.18 years) and their teachers from 35 classes in 19 schools who were followed longitudinally throughout first grade. Teacher–child conflict was measured during the first trimester (October to December), children's self‐esteem (three child interviews) during the second trimester (January to March) and children's aggressive behaviour during the first and third trimester (April to June). Teacher–child conflict had a significant indirect effect on changes in children's aggressive behaviour across first grade through its effect on children's self‐esteem.

The Role of Teacher Behavior Management in the Development of Disruptive Behaviors: An Intervention Study with the Good Behavior Game

The role of teacher behavior management for children’s disruptive behavior development (hyperactive and oppositional behavior) was investigated using a universal classroom preventive intervention study. Five-hundred seventy children were followed from second to third grade of elementary school. Observations of teacher behavior management and children’s on-task and off-task classroom behavior and peer reports of hyperactive and oppositional behavior were available. Results showed that the reduced use of negative remarks of intervention teachers predicted children’s increase in on-task behavior and decrease in talking-out behavior. These improved children’s classroom behaviors in turn mediated the impact of the intervention on the development of hyperactive and oppositional behavior over the studied period. These results were similar for girls and boys. The results underscore the role of teachers’ classroom management strategies in improving children’s classroom behavior, which, in turn is an important component in the reduction of disruptive behavior development.     

Parenting and psychosocial development of IVF children: Review of the research literature

When in vitro fertilization is performed, the transition to parenthood takes place in a special way. Many hypotheses have been formulated about the possible (mainly negative) effects that this method of conception may have on the parent–child relationship and the child’s psychosocial development. Since the early 1990s, various studies have been carried out to investigate these assumptions. Overall, few significant differences have been found in the parent–child relationship and psychosocial development of children in IVF families and non-IVF families. Some of the studies have even determined that IVF parents experienced the relationship with the child more positively. A limited number of results indicate a more negative view of parenting in IVF families, especially in terms of allowing for autonomy and feelings of child vulnerability. In one particular study, indications were found for an increased incidence of behavioral and emotional problems in IVF children. Potential explanations for these findings (including methodological issues) and suggestions for future research are discussed.     

Distress in couples coping with cancer: a meta-analysis and critical review of role and gender effects

Research concerning distress in couples coping with cancer was integrated using meta-analysis and narrative critical appraisal. Individual levels of distress were determined more by gender than by the role of being the person with cancer versus that person's partner. That is, women reported consistently more distress than men regardless of their role (standardized mean difference = 0.31). The association between patient and partner distress within couples was only moderate (r = .29) but is sufficient to warrant further consideration of the notion that these couples react as an emotional system rather than as individuals. It is noteworthy that this association is not moderated by gender. With a general lack of comparison groups, the question of how much distress can be ascribed to the cancer experience cannot be answered decisively; elevations in distress are probably modest. We critically discuss these results, identify important unanswered questions, and indicate directions for future research. Attention needs to be directed toward factors other than cancer as direct influences of distress in these couples and to mediators and moderators of the cancer experience.

Age-related changes in decision making: comparing informed and noninformed situations

Advantageous decision making progressively develops into early adulthood, most specifically in complex and motivationally salient decision situations in which direct feedback on gains and losses is provided (Figner & Weber, 2011). However, the factors that underlie this developmental improvement in decision making are still not well understood. The current study therefore investigates 2 potential factors, long-term memory and working memory, by assigning a large developmental sample (7-29 years of age) to a condition with either high or low demands on long-term and working memory. The first condition featured an age-adapted version of the Iowa Gambling Task (IGT; Bechara, Damasio, Damasio, & Anderson, 1994; i.e., a noninformed situation), whereas the second condition provided an external store where explicit information on gains, losses, and probabilities per choice option was presented (i.e., an informed situation). Consistent with previous developmental IGT studies, children up to age 12 did not learn to prefer advantageous options in the noninformed condition. In contrast, all age groups learned to prefer the advantageous options in the informed conditions, although a slight developmental increase in advantageous decision making remained. These results indicate that lowering dependence on long-term and working memory improves children's advantageous decision making. The results additionally suggest that other factors, like inhibitory control processes, may play an additional role in the development of advantageous decision making.     

Bright light treatment has limited effect in subjects over 55 years with mild early morning awakening

31 subjects, age 55 yr. or older, suffering from mild early morning awakening were randomized to either a bright light (10,000 lux) or to a red dim light placebo condition (200 lux). Light exposure took place in the evening in the patients' homes, 60 to 30 min. before bedtime and lasted for 3 wk. The subjects kept a sleep diary for 2 wk. and wore an actigraph for 1 wk. both before treatment and at post-treatment. Of the eight sleep diary outcome variables, significant effects that could be attributed to the light treatment were only detected for time spent in bed after final morning awakening. None of the six actigraph outcome variables yielded any significant effect of the light therapy. Explanations for the limited therapeutic effects of bright light treatment obtained in the present study are discussed, such as the criteria defining early morning awakening, the selection procedure, problems with compliance, age of the sample, and the dose of light. The lack of an objective circadian marker in this study could represent a problem concerning the timing of the light exposure. Despite the limited success of bright light therapy in this study, bright light therapy should still be considered as a treatment option for early morning awakening.
