Toward a social psychophysiology of vagally mediated heart rate variability: Concepts and methods in self‐regulation,emotion, and interpersonal processes

Theory and research on self‐regulation, emotional adjustment, and interpersonal processes focus increasingly on parasympathetic functioning, using measures of vagally mediated heart rate variability (vmHRV) or respiratory sinus arrhythmia (RSA). This review describes models of vmHRV in these areas, and issues in measurement and analysis. We propose a framework organizing theory and research as examining (a) vmHRV as an individual difference or a situational response, and (b) resting, reactive, or recovery levels. Evidence supports interpretation of individual differences in resting vmHRV as a broad biomarker for adaptive functioning, but its specificity and underlying mechanisms require elaboration. Individual differences in vagal reactivity (i.e., trait‐like differences in vmHRV decreases during challenge or stress) are less commonly studied in adults and results are mixed. Many stressors and challenges evoke temporary decreases in vmHRV, and in some research self‐regulatory effort evokes increases. In a smaller literature, positive interpersonal experiences and some restorative processes increase resting vmHRV, whereas depletion of self‐regulatory capacity through related effort decreases it. Greater attention to conceptual distinctions regarding vmHRV constructs and several methodological issues will strengthen future research. Importantly, researchers should exercise caution in equating vmHRV with specific psychosocial constructs, especially in the absence of converging assessments and precise experimental manipulations.     

Student volunteer social support and infant intervention: A case study

The emphases in infant mental health have been in the three areas of supporting the mother-infant dyad through education, psychotherapy to help parents resolve emotional conflicts that interfere with the parent-infant interaction, and support during the acute crisis that follows an abnormal birth. The case described herein involves a child with a genetic defect born to competent parents, a chronic stressful situation that does not fit these categories. It became apparent in the first few months after the birth that both the child and parents were in need of some help in coping with the situation. An intervention was designed to help provide both the necessary stimulation for the baby and the needed emotional support for the family, while it acknowledged their skill and competencies as parents. This was done through the help of college student volunteers, who assisted the mother in the home. Developmental data recorded at birth, 7 months, 12 months, and 39 months indicate that the child is severely multiply handicapped. Interview data with the parents at those times document their personal and family difficulties, the eventual resolution as a family in dealing with this problem, and the importance of the volunteer help during that process.     

Psychological Flexibility at Work and Employees' Proactive Work Behaviour: Cross‐Level Moderating Role of Leader Need for Structure

How to promote employees to be proactive behaviourally is a significant issue in the literature because it would benefit organisations in several ways. Drawing on the acceptance and commitment model, we proposed a new antecedent, psychological flexibility that might contribute to employees' proactive work behaviour. Furthermore, we investigated how the contextual role of supervisor need for structure exhibits a cross‐level moderating effect on the relationship between employee psychological flexibility at work and proactive work behaviour based on interactionism. Data from 241 full‐time employees and their corresponding 45 managers indicated that employee psychological flexibility was positively associated with proactive work behaviour. More importantly, the supervisor need for structure played a moderating role, suggesting that employees would demonstrate greater proactive work behaviour especially when the supervisors have a high need for structure. Implications for psychological flexibility, proactivity, and person‐situation interactional research are discussed.     

Conjoint developmental trajectories of young adult alcohol and tobacco use

Developmental and etiological advances have set the stage for considering trajectories of problem behavior across the life course, but little work thus far addresses co-occurring problem behavior trajectories. Although recent work characterizes drinking and smoking trajectories, none has explored the course of concurrent drinking and smoking. Using panel data from the Monitoring the Future Project (N=32,087), the authors applied growth mixture modeling to 4 waves of heavy drinking and smoking in a young-adult sample. The authors extracted a single latent group membership factor from heavy drinking and smoking. Associations between trajectory classes and risk factors were relatively unique to the substance being predicted. The association of smoking with alcohol expectancies and delinquency appeared to exist by virtue of smoking's comorbidity with drinking.     

Culture and self: are there within-culture differences in self between metropolitan areas and regional cities?

Although differences in self-conception across cultures have been well researched, regional differences within a culture have escaped attention. The present study examined individual, relational, and collective selves, which capture people's conceptions of themselves in relation to their goals, significant others, and in groups, comparing Australians and Japanese participants living in regional cities and metropolitan areas. Culture, gender, and urbanism were found to be related to individual, relational, and collective selves, respectively. Australians emphasized individual self more than Japanese, women stressed relational self more than men, and residents in regional cities regarded collective self as more important than their counterparts in metropolitan areas. These findings provide support for the tripartite division of the self and suggest a need to construct a culture theory that links self and societal processes.     

Something from nothing: exploring dimensions of children's knowing through the repeated reading of favourite books

Witte‐Townsend and DiGiulio explore some of the dimensions of knowing that children, teachers and parents may engage together during story‐time. They reflect on some of their own long‐term relationships with children and children's books, especially Phoebe Gilman's Gilman P 1992 Something from nothing (New York, NY, Scholastic Inc)  [Google Scholar] Something from nothing (published in 1992) and Simms Taback's Taback S 1999 Joseph had a little overcoat (New York, NY, Viking‐Penguin)  [Google Scholar] Joseph had a little overcoat, published in 1999. The authors probe issues such as why children ask to hear a favourite story over and over and why they suddenly abandon all interest and move on to a new book. They explore the meaning of the silences that sometimes arise during story‐time, pooling around the young listeners as the last words of the book are read. Witte‐Townsend and DiGiulio remind us of the value of literature in the lives of children and they affirm that the reading and re‐reading of favourite stories enables the understanding of complex human issues and contributes significantly to social, emotional and spiritual growth.     

Investigating the influence of organizational role on perceptions of risk in deep coal mines

The authors replicated O. Ostberg's (1980) study of forestry workers using a range of personnel groups in coal mines. Findings demonstrate a high level of consensus between a range of personnel groups for a set of pictorially depicted behavioral risks, at the level of rank order, but significant differences in terms of relative magnitudes. Magnitudes of perceived risk were found to be greater for those closest to the point of hazard than for members of more geographically and experientially distal groups. Findings are interpreted with reference to experiential influences associated with organizational role. Revealed differences between personnel groups are explained in terms of cognitive availability, specifically effects associated with habituation and familiarity with risk, these sources of perceptual bias appearing to interact with organizational role.     

Microstructure of eating behavior associated with Rorschach characteristics in obesity

The relationship between the microstructure of eating behavior and personality aspects according to the Rorschach Comprehensive System (Exner, 1991, 1993) was investigated among obese participants (N = 32). Eating behavior was measured using a computerized eating monitor, VIKTOR (Cabmek, Stockholm, Sweden), calculating initial eating rate and the eating curve. A higher initial eating rate reflecting eating drive was associated with Rorschach signs of stress overload according to the D Score and higher affective responsiveness to external stimuli seen in the Affective ratio. The stress overload may prompt eating, and affective responsiveness may be linked to appetite through a higher sensitivity to food stimuli, thus increasing eating drive. An accelerating rate of consumption during the meal was associated with intense emotionality and oral dependency, suggested by Pure C and Food responses.
