Measurement of Impulsivity: Construct Coherence, Longitudinal Stability, and Relationship with Externalizing Problems in Middle Childhood and Adolescence

This study focused on the assessment of impulsivity in nonreferred school-aged children. Children had been participants since infancy in the Bloomington Longitudinal Study. Individual differences in impulsivity were assessed in the laboratory when children were 6 (44 boys, 36 girls) and 8 (50 boys, 39 girls) years of age. Impulsivity constructs derived from these assessments were related to parent and teacher ratings of externalizing problems across the school-age period (ages 7–10) and to parent and self-ratings of these outcomes across adolescence (ages 14–17). Consistent with prior research, individual measures of impulsivity factor-analyzed into subdimensions reflecting children's executive control capabilities, delay of gratification, and ability or willingness to sustain attention and compliance during work tasks. Children's performance on the main interactive task index, inhibitory control, showed a signficant level of stability between ages 6 and 8. During the school-age years, children who performed impulsively on the laboratory measures were perceived by mothers and by teachers as more impulsive, inattentive, and overactive than others, affirming the external validity of the impulsivity constructs. Finally, impulsive behavior in the laboratory at ages 6 and 8 predicted maternal and self-ratings of externalizing problem behavior across adolescence, supporting the longterm predictive value of the laboratory-derived impulsivity measures.     

Divorce in the kibbutz: Affective responses to separation

This article is part of a comprehensive research project in which the central characteristics of the process of divorce in the kibbutz were examined. It appears that the framework of the kibbutz, free as it is from socio-economic pressures and boundary factors not directly connected with the marital relationship as such, provides an excellent and perhaps unique opportunity to investigate the pure emotional effects of the marital breakup.     

Measuring and modeling facial affect

In recent years, researchers in computer science and human-computer interaction have become increasingly interested in characterizing perception of facial affect. Ironically, this applied interest comes at a time when the classic findings on perception of human facial affect are being challenged in the psychological research literature, largely on methodological grounds. This paper first describes two experiments that empirically address Russell’s methodological criticisms of the classic work on measuring “basic emotions,” as well as his alternative approach toward modeling “facial affect space.” Finally, a user study on affect in a prototype model of a robot face is reported; these results are compared with the human findings from Experiment 1. This work provides new data on measuring facial affect, while also demonstrating how basic and more applied research can mutually inform one another.     

Heart rate variability predicts self‐control in goal pursuit

The aim of our study was to investigate the effects of a failure experience on the exercise of self‐control in goal pursuit. We hypothesized that tonic heart rate variability (tonic HRV), a possible physiological marker of inhibitory capacity, increases the exercise of self‐control in the pre‐ and post‐actional phase in goal pursuit after failure. Participants received feedback for an alleged intelligence test and subsequently worked on the same test again. As indicators of exercised self‐control, we assessed self‐confidence in the pre‐actional phase and rumination in the post‐actional phase. As hypothesized, tonic HRV was positively associated with pre‐ and post‐actional self‐control, even after controlling for the effect of neuroticism. We discuss the implications of our results for the self‐regulatory strength model. Copyright © 2009 John Wiley & Sons, Ltd.     

Hypothalamic Pituitary Adrenal Axis Functioning in Reactive and Proactive Aggression in Children

The purpose of this study was to examine the association between hypothalamic-pituitary-adrenal axis (HPA-axis) reactivity and proactive and reactive aggression in pre-pubertal children. After a 30-min controlled base line period, 73 7-year-old children (40 males and 33 females) were randomly assigned to one of two experimental tasks designed to elicit fear (N = 33) or frustration (N = 32), or a validity check condition (N = 8). This was followed by a 60-min controlled regulation phase. A total of 17 saliva samples for cortisol analysis were collected including 12 post-stress samples at 5-min intervals. Reactive and proactive aggression levels were assessed via the teacher-completed Aggression Behavior Teacher Checklist (Dodge and Coie, J Pers Soc Psychol, 53(6), 1146–1158, 1987). Reactive aggression significantly predicted total and peak post-stress cortisol regardless of stress modality. Proactive aggression was not a predictor of any cortisol index. Examination of pure reactive, proactive, combined, or non-aggressive children indicated that reactive aggressive children had higher cortisol reactivity than proactive and non-aggressive children. Our data suggest that while an overactive HPA-axis response to stress is associated with reactive aggression, stress induced HPA-axis variability does not seem to be related to proactive aggression.     

The demands and capacities model: Response to siegel

Responses to the recent critical comments of Gerald Siegel to the demands and capacities model are given. A brief history of the model's development is followed by direct explanations of its empirical support and logical development. It appears that Dr. Siegel may have referred only to one of our publications on the model. His concern about difficulties in measuring capacities is also addressed. Finally, the logic of the model is explicated and a misunderstanding regarding the use of direct therapy is clarified.     

Early risk pathways to physical versus relational peer aggression: The interplay of externalizing behavior and corporal punishment varies by child sex

Children who aggress against their peers may use physical or relational forms, yet little research has looked at early childhood risk factors and characteristics that uniquely predict high levels of relational versus physical aggression in preadolescence. Accordingly, the main aim of our study was to link early corporal punishment and externalizing behavior to children's physical and relational peer aggression during preadolescence and to examine how these pathways differed by sex. Participants were 193, 3‐year‐old boys (39%) and girls who were reassessed following the transition to kindergarten (5.5 years) and preadolescence (10.5 years). A series of autoregressive, cross‐lagged path analyses were conducted to examine the relationships between child externalizing problems and corporal punishment at ages 3 and 5.5 years, and their association with physical and relational aggression at age 10.5. Multiple group analysis was used to determine whether pathways differed by sex. Three developmental pathways were identified: (i) direct associations between stable childhood externalizing problems and later physical aggression; (ii) a direct pathway from early corporal punishment to preadolescent relational and physical peer aggression; and (iii) an indirect pathway from early corporal punishment to later physical aggression via continuing externalizing problems in middle childhood. Child sex moderated the nature of these pathways, as well as the direction of association between risk and outcome variables. These data advance our understanding of the etiology of distinct forms of peer aggression and highlight the potential for more efficacious prevention and intervention efforts in the early childhood years.
