Resilient Responses to Macro Stressors in Sub-Saharan African Populations: Evidence from the ResiMETA Database

Abstract (Expand)

In this subproject of the broader ResiMETA initiative, we will examine responses to macro stressors in Sub-Saharan African populations. The project will synthesize existing knowledge on the prevalence … of prototypical stress responses and the evidence on psychosocial resilience factors.

Perceived Control as a Resilience Factor: Influences on neural, physiological and affective stress responses and mental health

Abstract (Expand)

Perceived control is a key mechanism implicated in stress resilience. A tendency to perceive control over stressors may protect individuals against negative outcomes across various situations by … increasing active coping and preventing exacerbated stress reactions. Assuming that individual differences in perceived control during an uncontrollable stress task may represent an underlying resilience factor, we investigated associations of perceived control with neural, endocrine, and affective responses to a different, psychosocial stressor, and with overall mental health. 116 male participants aged 18-30 completed a psychosocial stress task, and we assessed stress responses via functional magnetic resonance imaging, cortisol levels, and affective state questionnaires. General mental health was assessed via self-report. Perceived control was measured during a second, uncontrollable stress task and growth mixture modeling revealed a high- and a low-control class. Comparison of these classes showed that the high-control class experienced less helplessness during the uncontrollability task and demonstrated more flexible responses to psychosocial stress as reflected in cortisol secretion and activation of the bilateral posterior insula. Further, the high-control class reported fewer psychosomatic symptoms and a less external locus of control. These findings suggest that perceived control acts as a resilience factor, influencing stress processing across multiple domains. The study highlights the potential for perceived control to be harnessed in resilience-building interventions and underscores the need for further experimental and longitudinal research to confirm its role in modulating stress responses.

Variability in negative affect is an important feature of neuroticism above mean negative affect once measurement issues are accounted for

Abstract (Expand)

Neuroticism is an important predictor of well-being that is conceptualized by high levels of mean negative affect and negative affect variability. However, research has shown that negative affect … variability only explained limited additional variance in neuroticism when the confound with mean negative affect was accounted for using a modified version of the standard deviation ( SD), the relative standard deviation ( RSD). Here, we (a) examined the suitability of the RSD as a variability measure, (b) introduced the number of negative affect episodes as an alternative measure of negative affect variability, and (c) investigated the relationship between neuroticism and negative affect variability, accounting for measurement error. Re-analyzing three experience sampling datasets ( N = 430 participants), we found several issues with the RSD, which limits its use as a negative affect variability measure, and which were not found for the number of negative affect episodes measure. Moreover, only the SD and the number of negative affect episodes explained substantial variance in neuroticism above mean negative affect. Thus, neuroticism was associated with experiencing negative affect more strongly and more often in daily life, when measurement error was accounted for, which demonstrates the importance to model reliability and to correct accordingly.

Be Kind to Yourself: the Implications of Momentary Self-Compassion for Affective Dynamics and Well-Being in Daily Life.

Abstract (Expand)

OBJECTIVES: While self-compassion (SC) has mostly been understood as a stable trait-like property, growing evidence suggests that it may fluctuate over time within a given individual. However, little … is known on how these fluctuations relate to affective well-being and affective dynamics, such as emotional inertia and stress reactivity in daily life. METHODS: A sample of 119 non-clinical individuals (mean age: 31.3 years, 53.8% female) completed a 7-day smartphone-based ecological momentary assessment study with six semi-random signals per day. With each signal, individuals reported their momentary positive affect (PA) and negative affect (NA), recent SC, and occurrence and perceived strain of daily hassles since the last signal. RESULTS: Whenever individuals reported higher recent SC than usual, they experienced higher momentary PA and lower momentary NA. Moreover, higher recent SC related to lower stress reactivity in terms of lower decrease of PA and lower increase of NA following the experience of daily hassles. No associations between SC and emotional inertia were found. When distinguishing between the positive components (SC-Pos) and negative components (SC-Neg) of SC, SC-Neg (compared to SC-Pos) was more strongly connected to NA, while SC-Pos and SC-Neg were similarly connected to PA. SC-Pos was associated with an attenuated NA stress reactivity, and SC-Neg with an increased NA stress reactivity. SC-Pos and SC-Neg did not significantly moderate PA stress reactivity nor emotional inertia. CONCLUSIONS: Results show that the benefits of SC for well-being and stress reactivity may unfold whenever we treat ourselves with compassion, irrespective of how self-compassionate we are in general.

Frigyes Riesz and the emergence of general topology

Abstract (Expand)

In 1906, Frigyes Riesz introduced a preliminary version of the notion of a topological space. He called it a mathematical continuum. This development can be traced back to the end of 1904 when, genuinely … interested in taking up Hilbert’s foundations of geometry from 1902, Riesz aimed to extend Hilbert’s notion of a two-dimensional manifold to the three-dimensional case. Starting with the plane as an abstract point-set, Hilbert had postulated the existence of a system of neighbourhoods, thereby introducing the notion of an accumulation point for the point-sets of the plane. Inspired by Hilbert’s technical approach, as well as by recent developments in analysis and point-set topology in France, Riesz defined the concept of a mathe- matical continuum as an abstract set provided with a notion of an accumulation point. In addition, he developed further elementary concepts in abstract point-set topology. Taking an abstract topological approach, he formulated a concept of three-dimensional continuous space that resembles the modern concept of a three-dimensional topolog- ical manifold. In 1908, Riesz presented his concept of mathematical continuum at the International Congress of Mathematicians in Rome. His lecture immediately won the attention of people interested in carrying on his research. They promoted his ideas, thus assuring their gradual reception by several future founders of general topology. In this way, Riesz’s work contributed significantly to the emergence of this discipline.
