Genetic and Environmental Pathways Underlying Personality Traits and Perceived Stress: Concurrent and Longitudinal Twin Studies

The present study examined the genetic and environmental etiology underlying the Big Five personality traits and perceived stress, concurrently and longitudinally. In study 1, we used the twin sample from the National Longitudinal Study of Adolescent to Adult Health (Add Health IV) data. The results indicated that about 70% of the association between the Big Five personality traits and perceived stress was due to genetic influences. In study 2, we used the twin sample from the Midlife in the United States Survey (MIDUS I and II) to examine the genetic and environmental influences underlying the longitudinal relations between the Big Five personality traits and perceived stress. The results suggested that continuity in perceived stress was primarily accounted for by genetic influences, and changes in perceived stress were mainly due to nonshared environmental influences. The continuity in the association between the five personality traits and perceived stress was largely accounted for by genetic factors, and nonshared environmental factors made greater contributions to changes in the association between personality traits and perceived stress. Among the Big Five personality traits, the genetic components in conscientiousness and neuroticism made substantial contributions to the genetic link between personality traits and perceived stress across both studies.

Assessing the Mediating Effect of Relationship Dynamics Between Perceptions of Problematic Media Use and Relationship Satisfaction

Previous research has indicated that it is common for couples to experience conflict over media use. However, until recently clinicians and researchers have not explored the implications of media use within romantic relationships. The purpose of this study is to examine the relationship between individuals’ perception of problematic media use in connection with relationship satisfaction, and to what extent demand-withdraw and criticism-defensiveness dynamics mediate this association. Data was collected with a sample of 242 respondents completing an online survey. Results showed that demand-withdraw and criticism-defensiveness patterns were found to be negatively associated with relationship satisfaction, and that the association between problematic media use and relationship satisfaction was partially mediated by the demand-withdraw and criticism-defensiveness patterns. Based on these results, there is potential for clinicians to view couple media use as a process level interaction, and by doing so, clinicians will be better able to implement interventions that utilize clients’ media use to promote relationship satisfaction and stability while reducing problematic media use.     

The Emotional Foundation of Political Cognition: The Impact of Extrinsic Anxiety on the Formation of Political Tolerance Judgments

Common sense recognizes emotion's ability to influence judgments. We argue that affective processes, in addition to generating feeling states, also influence how political cognition is manifested. Drawing on the theory of affective intelligence, we examine the role that anxiety plays in how and when people rely on predispositions and when they rely on contemporaneous information in making political tolerance judgments. We report on two experimental studies to test our arguments. In the first study we find that extrinsic anxiety generates a resistance response among subjects who hold a strong predisposition and a receptive response among those who do not. In the second study we present subjects with explicit "frames" exposing them to a pro- or anti-free speech message. We find that extrinsic anxiety enhances responsiveness to frames while an absence of anxiety diminishes the impact of these frames. Taken together these results show that affective processes shape how people make political judgments.     

The relationships between parenting stress,parenting behaviour and preschoolers' social competence and behaviour problems in the classroom

Young children develop social and emotional competence through interactions with others in the two major contexts in which they spend time: home and preschool. This study examined whether parenting stress in the home context is related to the children's behaviour while in preschool. Previous research has suggested that parenting stress negatively influences parenting behaviour, which in turn has been shown to impact children's development. This study examined the direct relationship between parenting stress and children's behaviour in two types of preschool programmes: private day care centres and Head Start. Parenting stress was significantly related to teacher ratings of social competence, internalizing behaviours, and externalizing behaviours, and the effects of parenting behaviour do not appear to mediate this relationship. Parenting stress was most strongly related to children's social competence. Parents' reports of expectations for their child's behaviour appear to weakly moderate the relationship between externalizing behaviour and parenting stress. This study suggests that examination of a parent's level of stress, in addition to parenting practices, may be important in research and interventions with preschool children's behaviour and social competence.

Building Trust in Business Schools Through Ethical Governance

This paper presents conceptual arguments to suggest that trust within organizations and trustworthiness of organizations are built through ethical governance mechanisms. We ground our analysis of trust, trustworthiness, and stewardship in the business literature and provide the context of business school governance as the focus of our paper. We present a framework that highlights the importance of knowledge, resources, performance focus, transparency, authentic caring, social capital and citizenship expectations in creating a basis for the ethical governance of organizations. A version of this paper was presented at the European Academy of Management, 2005.     

Affect and automatic mood maintenance

The hedonic contingency model (HCM; Wegener & Petty, 1994) states that individuals have learned to seek out positive activities while in a happy mood in order to maintain or elevate that mood. We argue that this tendency may become overlearned and, thus, automated. More specifically, the experience of a happy mood was predicted to automatically activate the mood-maintenance tendency proposed by the HCM. Participants induced into happy, sad, or neutral moods ranked their preferences for future activities that were nonconsciously associated with either a positive or negative valence. Supporting the notion of automatic mood maintenance, happy participants appeared to evaluate the affective qualities of the future activities and base their preferences on this evaluation without realizing that they were doing so. Theoretical implications of this finding are discussed.     

Two-Dimensional Time: MacBeath's ``Time's Square' and Special Relativity

Murray MacBeath, in his essay ``Time's Square', describes a fictitious scenariowhere various physical observations made by the participants would, he claims, invitethe interpretation that time for them is two-dimensional. In the present paper, however, Iargue that such observations come close to underdetermining the hypothesis of time's twodimensionality;for a rival hypothesis - that, under certain circumstances, the observationscan be explained in terms of the familiar time dilation effects predicted by special relativity- almost fits the evidence as well. That is, under certain (albeit artificial) circumstances theworld can already behave almost as though it were temporally two-dimensional.
