The Role of Physical Activity in the Lives of Researchers: A Body-Narrative

Physical movement as a cohesive rhythmic mediumfor better understanding the qualities of livedexperience, keeps us intimately connected toour selves, others and our environment.Incorporating elements of evocativeautoethnography (Ellis, 1997), this workemploys the implicated reading (Pearce, 1997)of the authors' co-constructed body narrativeas a necessary analytical and representationaldevice for better understanding the embodiedand relational qualities of research. Pullingfrom Dewey's theories of naturalism,qualitative thought, and aesthetics,researchers relive and re-present theirmovement (running) experience as practice forembodied approaches to more authentic research.In the process, researchers discover thatrunning as a shared rhythmical threadilluminated intersections in their lives andtheir research, nurtured universal qualities ofembodied experience often unexplored inresearch, and served as kinesthetic practicefor more fully understanding the contextualqualities of experience that informunderstanding.     

The Impact of Exercise on Hormones Is Related to Autonomic Reactivity to a Mental Task

This study examined the effects of an acute physical stressor on salivary testosterone (Tsal) and cortisol (Csal) and their relationship with the autonomic responsiveness to a mental task in fit young men (n = 30). Salivary testosterone (Tsal) and cortisol (Csal) levels were determined before and after a maximal bicycle exercise. Heart rate (HR) and skin conductance levels (SCL) were continuously recorded before, during, and after a Stroop task. Tsal and Csal levels diminished while HR and SCL increased in response to stressors in all the sample. When subjects were distributed in function of their endocrine response to the physical stressor, high Tsal responders showed higher HR reactivity than low responders, and high Csal responders showed higher SCL reactivity and lower reaction time in the Stroop task. These results show that the influence of an acute physical stressor on hormones is associated with the autonomic responses to a mental task.

FURTHER EVALUATION OF ANTECEDENT SOCIAL EVENTS DURING FUNCTIONAL ANALYSIS

The value of a reinforcer may change based on antecedent events, specifically the behavior of others (Bruzek & Thompson, 2007). In the current study, we examined the effects of manipulating the behavior of the therapist on problem behavior while all dimensions of reinforcement were held constant. Both participants' levels of problem behaviors increased as a function of the altered behavior of the therapist without direct manipulation of states of satiation or deprivation.     

Personality moderates the interaction between positive and negative daily events predicting negative affect and stress

A 30-day diary study examined personality moderators (neuroticism and extraversion) of the interaction between positive and negative daily events predicting daily negative affect and night-time stress. Multilevel analyses revealed positive daily events buffered the effect of negative daily events on negative affect for individuals low in neuroticism and individuals high in extraversion, but not for individuals high in neuroticism or individuals low in extraversion. Positive daily events also buffered the effect of negative daily events on that night’s stress, but only for participants low in neuroticism. As such, this research linked today’s events to tonight’s stressfulness. This study advances our understanding of how neuroticism and extraversion influence within-person associations between positive and negative events predicting negative affect and stress.     

Rough‐and‐tumble play and the regulation of aggression: an observational study of father–child play dyads

Rough‐and‐tumble play (RTP) is a common form of play between fathers and children. It has been suggested that RTP can contribute to the development of selfregulation. This study addressed the hypothesis that the frequency of father–child RTP is related to the frequency of physically aggressive behavior in early childhood. This relationship was expected to be moderated by the dominance relationship between father and son during play. Eighty‐five children between the ages of 2 and 6 years were videotaped during a free‐play session with their fathers in their homes and questionnaire data was collected about father–child RTP frequency during the past year. The play dyads were rated for the degree to which the father dominated play interactions. A significant statistical interaction revealed that RTP frequency was associated with higher levels of physical aggression in children whose fathers were less dominant. These results indicate that RTP is indeed related to physical aggression, though this relationship is moderated by the degree to which the father is a dominant playmate. Aggr.

Development and validation of the Subtypes of Antisocial Behavior Questionnaire

There is converging evidence that physical aggression, rule‐breaking, and social aggression constitute meaningfully distinct, if somewhat overlapping, components of the broader construct of antisocial behavior. Indeed, these subtypes appear to have different developmental trajectories, demographic correlates, and personological underpinnings. They also demonstrate important etiological distinctions. One potential limitation to accumulating additional scientific insights into the correlates and origins of these three types of antisocial behavior is the lack of an efficient self‐report assessment in the public domain. We developed the 32‐item Subtypes of Antisocial Behavior Questionnaire (STAB) to fill this gap. Our goal was to develop a brief measure that could reliably and validly assess each of the three major subtypes of antisocial behavior and that would be freely available for other researchers. The present series of studies provides initial evidence of the factorial validity, internal consistency, and criterion‐related validity of the STAB scales. In short, it appears that the STAB is a brief and useful measure that can be used to differentiate and assess physically aggressive, rule‐breaking, and socially aggressive forms of antisocial behavior.

Social status and shaming experiences related to adolescent overt aggression at school

Feelings of rejection and humiliation in interpersonal interaction are strongly related to aggressive behavior. The aim of this study was to investigate the association between social status, shaming experiences, gender and adolescent aggressive behavior by using a status-shaming model. A population-based sample of 5,396 adolescents aged from 15 to 18 completed a questionnaire that asked questions regarding psychosocial background, shaming experiences, social status of family, peer group and school and involvement in physical or verbal aggression at school. Shaming experiences, i.e. being ridiculed or humiliated by others, were strongly related to aggressive behavior. Social status and shaming were related in the prediction of aggressive behavior, suggesting that a person's social status may influence the risk for taking aggressive action when subjected to shaming experiences. Medium social status seemed to have a protective function in the association between shaming experiences and aggression. This study confirms the importance of further evaluation of the role of perceived social status and shaming experiences in the understanding of aggressive behavior. Moreover, the results indicate the need for different kinds of status measures when investigating the associations between status and behavior in adolescent populations. The results may have important implications for the prevention of bullying at school as well as other deviant aggressive behavior among adolescents.     

从婴儿期到成年期的依恋稳定性

Bowlby依恋理论的核心假设是婴儿时期的依恋模型影响着个体成年时的依恋表征,这涉及依恋稳定性的问题.围绕这一问题,很多心理学家开展了实证研究.随着成人依恋访谈的出现,人们开始进行长期的追踪研究.人们对于早期依恋表征是如何影响成人依恋模型的内在机制,形成了修正论和原型论两种观点.本文主要介绍依恋稳定性的研究进展和内在机制的理论探讨,并就当前依恋稳定性研究的不足进行展望.
