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.     

Social anxiety and posttraumatic stress in combat veterans: relations to well-being and character strengths

There are few studies examining the relationship between psychopathology and positive experiences and traits. Although initial studies suggest persons with posttraumatic stress disorder (PTSD) are at increased risk for excessive social anxiety, there have been no studies to date evaluating how these conditions might interact to affect positive experiences and traits. Using self-report scales, informant ratings, and experience-sampling methodologies, we examined the association of social anxiety with well-being and character strengths in veterans with and without PTSD. Controlling for PTSD and trait negative affect, social anxiety was negatively related to global ratings of well-being and character strengths. Social anxiety also accounted for incremental variance in day-to-day well-being (i.e., daily affect balance, percentage of pleasant days, positive social activity, self-esteem, gratitude) over a 14-day assessment period. Although veterans with PTSD reported lower levels of global and daily well-being and character strengths than veterans without PTSD, a diagnosis of PTSD failed to exhibit unique relationships with these constructs. Building on a growing body of work, these data suggest that social anxiety is uniquely associated with disturbances in positive experiences, events, and traits. Our findings support the value of directly addressing social anxiety in the study and treatment of PTSD.     

Preattentive processing of alcohol stimuli

An experiment was conducted to test the automatic analysis of briefly presented alcohol stimuli in alcohol-dependent individuals. Alcoholics and controls were exposed to four different conditions: two brief (30 ms) and two long (130 ms) exposure conditions, each containing alcoholic and non-alcoholic pictures. Heart rate (HR) interbeat intervals were recorded and phasic cardiac responses assessed. Alcoholics had a stronger initial HR deceleration after exposure to masked alcohol slides compared with masked control slides, indicating a preattentive analysis of alcohol stimuli. This initial HR deceleration in the masked condition suggests an automatic attentional focusing to degraded alcohol cues. No such attentional effect was found when the pictures were presented unmasked and were clearly perceived. The implication of these results for the understanding of relapse in addictive behavior is discussed.     

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.     

Modeling the Development of Children's Use of Optional Infinitives in Dutch and English Using MOSAIC

In this study we use a computational model of language learning called model of syntax acquisition in children (MOSAIC) to investigate the extent to which the optional infinitive (OI) phenomenon in Dutch and English can be explained in terms of a resource-limited distributional analysis of Dutch and English child-directed speech. The results show that the same version of MOSAIC is able to simulate changes in the pattern of finiteness marking in 2 children learning Dutch and 2 children learning English as the average length of their utterances increases. These results suggest that it is possible to explain the key features of the OI phenomenon in both Dutch and English in terms of the interaction between an utterance-final bias in learning and the distributional characteristics of child-directed speech in the 2 languages. They also show how computational modeling techniques can be used to investigate the extent to which cross-linguistic similarities in the developmental data can be explained in terms of common processing constraints as opposed to innate knowledge of universal grammar.     

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.
