Associations of perceived stress and state anger with symptom burden and functional status in patients with heart failure

Abstract

Background: Psychosocial stress and anger trigger cardiovascular events, but their relationship to heart failure (HF) exacerbations is unclear. We investigated perceived stress and anger associations with HF functional status and symptoms.

Methods and Results: In a prospective cohort study (BETRHEART), 144 patients with HF (77% male; 57.5?±?11.5 years) were evaluated for perceived stress (Perceived Stress Scale; PSS) and state anger (STAXI) at baseline and every 2 weeks for 3 months. Objective functional status (6-min walk test; 6MWT) and health status (Kansas City Cardiomyopathy Questionnaire; KCCQ) were also measured biweekly. Linear mixed model analyses indicated that average PSS and greater than usual increases in PSS were associated with worsened KCCQ scores. Greater than usual increases in PSS were associated with worsened 6MWT. Average anger levels were associated with worsened KCCQ, and increases in anger were associated with worsened 6MWT. Adjusting for PSS, anger associations were no longer statistically significant. Adjusting for anger, PSS associations with KCCQ and 6MWT remained significant.

Conclusion: In patients with HF, both perceived stress and anger are associated with poorer functional and health status, but perceived stress is a stronger predictor. Negative effects of anger on HF functional status and health status may partly operate through psychological stress.     

The Impact of Phantom Decoys on Choices and Perceptions

Phantoms are dominating, attractive alternatives that are unavailable at the time of choice. They occupy different positions in the attribute space, and their unavailability can be either known or unknown to individuals. Although different theories have offered explanations for the influence that phantoms exert on individual choices, they have largely overlooked phantom knowledge. Contradictory predictions can be drawn from these theories, and none provides a good account of the pattern of effects that emerges from our data. We suggest that these contradictions appear because the different theories do not address phantom location and knowledge jointly. When considering phantom knowledge together with location, we observe a consistent overall pattern of effects that encompasses all predictions that could be made on the basis of each theory. We find that known phantoms are stronger when close, and favor the target product, whereas unknown phantoms are stronger when far, and favor the competitor. Finally, we look beyond shifts in choice shares and find that phantom decoys can also affect individuals' post‐choice evaluations and reactions in terms of perceived justice, decision satisfaction, and repatronage intention. Our results show that post‐choice evaluations are driven by phantom knowledge, not phantom location. Copyright © 2012 John Wiley & Sons, Ltd.     

Alessandro Piccolomini and the certitude of mathematics

This paper offers a reconstruction of Alessandro Piccolomini's philosophy of mathematics, and reconstructs the role of Themistius and Averroes in the Renaissance debate on Aristotle's theory of proof. It also describes the interpretative context within which Piccolomini was working in order to show that he was not an isolated figure, but rather that he was fully involved in the debate on mathematics and physics of Italian Aristotelians of his time. The ideas of Lodovico Boccadiferro and Sperone Speroni will be analysed. This paper demonstrates that Piccolomini's attack on the certitude of mathematics was a product of discussions between Aristotelians.     

Reactive and Proactive Aggression in Childhood and Adolescence: Precursors, Outcomes, Processes, Experiences, and Measurement

ABSTRACT. This paper reviews and critiques the growing literature on the distinction between reactive and proactive aggression in children and adolescents. Empirical findings suggest that the subtypes of aggression are (a) preceded by different familial precursors, (b) associated with different behavioral outcomes, (c) driven by different social–cognitive and emotional processes, and (d) related to different social experiences. Because measurement difficulties have been a prominent concern in the study of reactive and proactive aggression, a discussion of various assessment approaches is included. Suggestions are made for future research directions, including a greater use of observational and laboratory-based methods, more longitudinal designs, and a greater focus on the careful assessment of the subtypes of aggression.     

Bridging music and speech rhythm: Rhythmic priming and audio–motor training affect speech perception

Following findings that musical rhythmic priming enhances subsequent speech perception, we investigated whether rhythmic priming for spoken sentences can enhance phonological processing – the building blocks of speech – and whether audio–motor training enhances this effect. Participants heard a metrical prime followed by a sentence (with a matching/mismatching prosodic structure), for which they performed a phoneme detection task. Behavioural (RT) data was collected from two groups: one who received audio–motor training, and one who did not. We hypothesised that 1) phonological processing would be enhanced in matching conditions, and 2) audio–motor training with the musical rhythms would enhance this effect. Indeed, providing a matching rhythmic prime context resulted in faster phoneme detection, thus revealing a cross-domain effect of musical rhythm on phonological processing. In addition, our results indicate that rhythmic audio–motor training enhances this priming effect. These results have important implications for rhythm-based speech therapies, and suggest that metrical rhythm in music and speech may rely on shared temporal processing brain resources.     

Emotional prosody: sex differences in sensitivity to speech melody

Emotional prosody is defined as the ability to express emotions through variations of different parameters of the human speech, such as pitch contour, intensity and duration. A recent study has discovered clear differences between men and women in the time course of emotional prosodic processing. There are several interpretations of these intriguing results that hold promise for future studies on language comprehension.     

Reasoning in moral conflicts

Following the assumptions of the mental model theory and its account of moral judgements, we argue for a main role of reasoning in moral judgements, especially in dealing with moral conflicts. In four experiments, we invited adult participants to evaluate scenarios describing moral or immoral actions. Our results confirm the predictions deriving from our assumptions: Given a moral or immoral scenario, the manipulation of the propositions which refer to norms and values results in a scenario eliciting a moral conflict (Experiment 1); when invited to create conflict versions from no-conflict versions of moral or immoral scenarios, individuals manipulate the propositions in the scenario which describe norms and values rather than emotional factors (Experiment 2); the evaluation of conflict scenarios takes longer than the evaluation of no-conflict scenarios (Experiment 3), and this is because conflict scenarios involve more deliberative reasoning (Experiment 4). We discuss our results in relation to competing theories of moral judgements.     

New Age Beliefs and Societal Risk Perception1

The New Age movement is a transpersonal movement focused on mystic awakening and human potential development. It has become an important component in modern risk discourse, as it often goes hand in hand with technology opposition and worries about technology risks. The present study examined the possible relationships between New Age beliefs and societal risk perception. It was shown that several hazards—particularly the ones at the center of current debates about security policies and environmental policies—were perceived as significantly riskier by the New Agers than by others. These (hot) hazards include nuclear waste storage, chemical plants, urban violence, genetically engineered organisms, marijuana, and hospital waste.     

The secure-base hypothesis: Global attachment, attachment to counselor, and session exploration in psychotherapy

This study explored J. Bowlby's (1988) secure-base hypothesis, which predicts that a client's secure attachment to the therapist, as well as the client's and the therapist's global attachment security, will facilitate in-session exploration. Volunteer clients (N = 59) and trainee counselors (N = 59) in short-term therapy completed the Experiences in Close Relationship Scale (K. A. Brennan, C. L. Clark, & P. R. Shaver, 1998) as a measure of adult global romantic and peer attachment orientations; the Client Attachment to Therapist Scale (B. Mallinckrodt, D. L. Gantt, & H. M. Coble, 1995) as a measure of attachment to counselor; the Working Alliance Inventory (A. O. Horvath & L. Greenberg, 1989) as a measure of working alliance; and the Session Evaluation Questionnaire-Depth Subscale (W. B. Stiles & J. S. Snow, 1984) as a measure of session depth. In line with Bowlby's hypothesis, the findings suggest that session depth is related to the client's experience of attachment security with the counselor and that counselor global attachment moderates the relationship between client global attachment and session exploration.
