Emotional irritation before mental stress is associated with enhanced peripheral norepinephrine

Research suggests equivocal findings on associations of catecholamines and mood. Our study investigated the associations of emotional state, blood pressure and catecholamines in 55 healthy males undergoing mental stress. We especially checked the reported link between norepinephrine (NE) and emotional irritation. Blood pressure (SBP, DBP) and heart rate (HR) were continuously monitored. NE and epinephrine (EPI) were measured before, after, and 20 minutes after stress. Participants were divided into irritated versus non-irritated and anxious versus non-anxious subjects by median split on their baseline questionnaires. The task elicited significant cardiovascular, hormonal, and psychological stress responses. NE levels were significantly correlated with irritation before stress. Irritated subjects showed significantly higher DBP and NE than non-irritated subjects. The higher NE and DBP levels in the irritated participants suggest detrimental psycho-physiological interrelations promoting the development of stress-mediated cardiovascular diseases. Heightened emotional irritation before stress may be regarded as a psychological risk factor.     

A study of the perceived recognition affecting the adoption of innovation with respect to the online game in Taiwan.

The potential of online games to become a major global business and the existence of limited related references led to the current study. In this study, Rogers's diffusion of innovation (DOI) theory is applied to investigate the principles for the adoption of online games in Taiwan. The findings suggest that relative advantages and compatibility both have a significant effect on the adoption of online games for purposes of amusement, with the former being more important for early gamers and the latter being regarded as more critical for later gamers. In addition, complexity is found to impede online game diffusion and is regarded as the most important facilitator.     

The self and social cognition: the role of cortical midline structures and mirror neurons

Recent evidence suggests that there are at least two large-scale neural networks that represent the self and others. Whereas frontoparietal mirror-neuron areas provide the basis for bridging the gap between the physical self and others through motor-simulation mechanisms, cortical midline structures engage in processing information about the self and others in more abstract, evaluative terms. This framework provides a basis for reconciling findings from two separate but related lines of research: self-related processing and social cognition. The neural systems of midline structures and mirror neurons show that self and other are two sides of the same coin, whether their physical interactions or their most internal mental processes are examined.     

Aroused at Home: Basic Autonomic Regulation during Orthostatic and Physical Activation is Altered in Children with Social Anxiety Disorder

Previous research has documented altered autonomic nervous system (ANS) reactivity to laboratory-based social stress tasks in children with social anxiety disorder (SAD). It is unclear, however, whether these alterations are caused by the unfamiliar and possibly threatening lab environment or whether they generalize to other, more representative contexts. Sympathetic and parasympathetic autonomic functioning was assessed in the home (minimizing environmental threat) during a supine baseline phase and two physical activation phases (orthostatic stress, stair stepping) in children (9–13 years) with SAD (n?=?27) and healthy control children (n?=?27). Relative to controls, children with SAD showed tonic autonomic hyperarousal as indicated by higher heart rate and electrodermal activity during the supine baseline phase. Further, there was evidence for stronger cardiac and vascular sympathetic reactivity (T-wave amplitude, pulse wave transit time) to moderate physical activation in children with SAD. Higher autonomic arousal during rest was related to measures of trait social anxiety and general psychopathology. Groups did not differ on parasympathetic parameters. Our results extend previous laboratory findings and provide the first evidence for alterations in children with SAD during basal autonomic regulation and in the absence of explicit social evaluative threat. They may further help to clarify conflicting study results from previous laboratory studies. The findings underline the importance of psychophysiological assessment using different environments and tasks to elucidate the physiological bases of SAD.     

Disaggregated pluralistic theories of global distributive justice – a critique

Pluralistic theories of global distributive justice aim at justifying a plurality of principles for various subglobal contexts of distributive justice. Helena de Bres has recently proposed the class of disaggregated pluralistic theories, according to which we should refrain from defending principles that apply to the shared background conditions of such subglobal contexts. This article argues that if one does not justify how these background conditions should be regulated by principles of a just global basic structure, then the (apparent) realization of the principles that are justified for the subglobal contexts of distributive justice can erode and undermine justice over time. For example, the realization of justice in international trade might undermine climate justice, at least if climate justice requires increasing tariffs (in order to mitigate greenhouse gas emissions) but justice in international trade calls for reducing tariffs (in order to create a level playing field). Principles of a just global basic structure would have to ensure that such justice-eroding spillover effects from one to another context of justice do not occur. Finally, the article responds critically to de Bres’ objections that an account of a just global basic structure is too idealistic, not action guiding, and superfluous.     

Companion Animal Ethics: A Special Area of Moral Theory and Practice?

Considerations of ethical questions regarding pets should take into account the nature of human-pet relationships, in particular the uniquely combined features of mutual companionship, quasi-family-membership, proximity, direct contact, privacy, dependence, and partiality. The approaches to ethical questions about pets should overlap with those of animal ethics and family ethics (and, for veterinary issues, with healthcare ethics), and so need not represent an isolated field of enquiry, but rather the intersection of those more established fields. This intersection, and the questions of how we treat our pets, present several unique concerns and approaches for focused examination.     

Central and autonomic nervous system integration in emotion

Emotions involve physiological responses that are regulated by the brain. The present paper reviews the empirical literature on central nervous system (CNS) and autonomic nervous system (ANS) concomitants of emotional states, with a focus on studies that simultaneously assessed CNS and ANS activity. The reviewed data support two primary conclusions: (1) numerous cortical and subcortical regions show co-occurring activity with ANS responses in emotion, and (2) there may be reversed asymmetries on cortical and subcortical levels with respect to CNS/ANS interrelations. These observations are interpreted in terms of a model of neurovisceral integration in emotion, and directions for future research are presented.     

Behavioural genetics: why eugenic selection is preferable to enhancement

Criminal behaviour is but one behavioural tendency for which a genetic influence has been suggested. Whilst this research certainly raises difficult ethical questions and is subject to scientific criticism, one recent research project suggests that for some families, criminal tendency might be predicted by genetics. In this paper, supposing this research is valid, we consider whether intervening in the criminal tendency of future children is ethically justifiable. We argue that, if avoidance of harm is a paramount consideration, such an intervention is acceptable when genetic selection is employed instead of genetic enhancement. Moreover, other moral problems in avoiding having children with a tendency to criminal behaviour, such as the prospect of social discrimination, can also be overcome.     

Enhancing Quality of Practice Through Theory of Change‐Based Evaluation: Science or Practice?

This paper describes the evaluation component of Partnerships for Success (PfS), a comprehensive community effort designed to address youth development issues. The evaluation component is referred to as theory of change-based evaluation. The author considers the implications of applying community practice tools such as theory of change-based evaluation to the current conceptualization of community science. More specifically, the author argues that the current conceptualization of community science pays scant attention to community practice. This paper concludes by suggesting that the current conceptualization of community science be modified to recognize the importance of community practice as an equal aspiration for community psychologists.
