Adverse childhood experiences and autonomic regulation in response to acute stress: the role of the sympathetic and parasympathetic nervous systems

Background and objectives: After a previous report demonstrated blunted heart rate (HR) reactivity in association with adverse childhood experiences (ACEs) [Voellmin, A., Winzeler, K., Hug, E., Wilhelm, F. H., Schaefer, V., Gaab, J.,?…?Bader, K. (2015). Blunted endocrine and cardiovascular reactivity in young healthy women reporting a history of childhood adversity. Psychoneuroendocrinology, 51, 58–67. doi:10.1016/j.psyneuen.2014.09.008], the present analysis aimed at clarifying the role of the sympathetic and parasympathetic branches of the autonomic nervous system in this relationship.

Design and Methods: One hundred eighteen healthy young women provided data on ACEs and underwent psychosocial stress testing. Systolic blood pressure (SBP) and respiratory sinus arrhythmia (RSA, quantified by high-frequency HR variability) were assessed as measures of sympathetic and parasympathetic cardiovascular activity, respectively. A mediation model was calculated to test the indirect effects of ACEs on HR via SBP and RSA.

Results: The effect of ACEs on HR reactivity was mediated by SBP reactivity but not by RSA reactivity. ACEs were associated with reduced SBP at rest.

Conclusions: ACEs were associated with down-regulation in a measure of sympathetic but no alteration in a measure of parasympathetic cardiovascular stress reactivity in adulthood. Future research will need to clarify whether this indicates risk or resilience.     

Well-being and Need for Support of Adolescents with a Chronically Ill Family Member

This study investigates whether there are differences in the well-being, need for help and use of support services between adolescents with and without a chronically ill or disabled family member. It also examines the role played by the type of illness, the relationship to the family member and the nature and intensity of the help provided by the adolescent. A Dutch sample of 1581 adolescents (average age 14.6?years) completed a questionnaire in 2010 about mental health problems, pro-social behavior, need for and use of support and the illness of family members and any care tasks performed by the respondent. Young people with a sick family member had more mental health problems than their counterparts without a chronically ill family member. They also reported a greater need for and use of help and support. Performing domestic tasks was found to be a predictor for overall mental health problems. The intensity of the help given was related to the need for help by the adolescent. It is concluded that growing up with a chronically ill family member and spending a lot time performing (domestic) tasks are risk factors for adolescent mental health problems and adolescents’ need for help. Special attention is warranted for those who need support but who do not translate that need into reality by seeking help.     

Increasing stimulus intensity does not affect sensorimotor synchronization

When people synchronize taps with isochronously presented stimuli, taps usually precede the pacing stimuli [negative mean asynchrony (NMA)]. One explanation of NMA [sensory accumulation model (SAM), Aschersleben in Brain Cogn 48:66–79, 2002] is that more time is needed to generate a central code for kinesthetic-tactile information than for auditory or visual stimuli. The SAM predicts that raising the intensity of the pacing stimuli shortens the time for their sensory accumulation, thereby increasing NMA. This prediction was tested by asking participants to synchronize finger force pulses with target isochronous stimuli with various intensities. In addition, participants performed a simple reaction-time task, for comparison. Higher intensity led to shorter reaction times. However, intensity manipulation did not affect NMA in the synchronization task. This finding is not consistent with the predictions based on the SAM. Discrepancies in sensitivity to stimulus intensity between sensorimotor synchronization and reaction-time tasks point to the involvement of different timing mechanisms in these two tasks.     

Trust as a Meta‐Emotion

The aim of this article is to present trust as a meta‐emotion, such that it is an emotion that precedes first‐order emotions. It examines how trust can be considered a meta‐emotion by establishing criteria for identifying trust as a meta‐emotion. How trust plays out differently in aesthetic and ordinary contexts can provide another mode for investigating meta‐emotions. The article illustrates how it is possible to recognize these meta‐emotions in narratives. Finally, it presents one of the aims of trust, sharing knowledge between agents, when someone who provides testimony shares knowledge in an epistemic trust process with others. It shows a relationship construction between subjects and objects thanks to the trust, a meta‐emotion that represents emotional ties between subjects to achieve another emotion.     

Distinguishing between attributional and mnemonic sources of familiarity: The case of positive emotion bias

Does familiarity arise from direct access to memory representations (a mnemonic account) or from inferences and diagnostic cues (an attributional account)? These theoretically distinct explanations can be difficult to distinguish in practice, as is shown by thepositivity effect, the increase in feelings of familiarity that accompanies positive emotion. Experiment 1 manipulated mnemonic and attributional sources of positivity via word valence and physical expressions of emotion, respectively. Both sources influenced the tendency to call itemsold, but receiver-operating characteristic analysis revealed a change in accuracy only with the mnemonic source. To further contrast the mnemonic and attributional accounts, Experiment 2 varied the ratio of positive to neutral words. A higher proportion of positive words exaggerated the pattern of increasedold judgments and decreased accuracy for positive words, relative to neutral ones, consistent with the mnemonic account but inconsistent with the attributional account.     

Begutachtung von somatoformen Störungen

As a result of their prevalence somatoform disorders represent a substantial burden not only for health care systems but also for social security and pension programs around the world. In fact, in recent years there has been a steady increase in the number of applicants filing for disability pensions due to such disorders. Recent studies focus on the relationship between biological, psychological and social factors and the subjective experience of somatoform symptoms and their concomitant impairments. Despite this progress, diagnostic work in general remains a challenge. The purpose of this paper is first to discuss a dimensional diagnostic system for somatoform disorders. Secondly based on the dimensions of this diagnostic system, considerations regarding the differentiation of the diagnosis “pain disorder” will be made. Furthermore, considerations concerning the severity and prognosis of somatoform disorders are presented. These considerations should help to assess vocational disability.     

The cognitive representation of intending not to act: Evidence for specific non-action-effect binding

The question how we represent voluntary action on a cognitive level has recently become of increasing interest to researchers studying motor control. However, so far it has been neglected how we represent the voluntary omission of an action. In our attempt to investigate the representation of voluntary non-actions we demonstrated binding effects between voluntary non-actions and subsequent action effects (Kühn, Elsner, Prinz, & Brass, 2009). That study, however, only distinguished between acting or not acting, and did not address the question of whether non-actions are coded as general omissions or whether they can be encoded specifically as the actual negation of the action in question (“not-right” or “not-left”). Our current study provides first evidence for the specificity of representations of intentional non-actions. Additionally, we compare two ways in which the specific non-actions might be represented: an ironic representation account implying that negations are prone to be omitted and a reformulated representation account assuming that the negated action is suppressed and/or the alternative action is facilitated. Our results suggest that the representation of non-actions contains a facilitation of the alternative action rather than a suppression of the action in question.     

A Smile is Just a Smile: But Only for Men. Sex Differences in Meaning of Faces Scales

This study tests psychometrics of the faces scale that is often used in organizational psychology to assess emotions, attitudes, and well-being. In analyzing 10,584 two-categorical judgments (“sad” versus “happy”) of 11 faces from 72 participants, women judged a face with a horizontal line as mouth (“neutral face”) more often sad than happy and significantly more often sad than men did. Moreover, women adapted their judgments to the range of faces under study in showing a significant contrast effect. In a range of neutral to bright smiling faces a face showing a mild smile was judged to be sad, while in a range of neutral to heavy griming faces a mild grim was judged to be happy. Sex differences in meaning of faces within faces scales and their implications for the use of the faces scale in work and organizational psychology are discussed.
