Article Synopsis
- - The study examines how the heart's response to scary sounds involves two main components: one related to attention and the other to safety actions, showing the body's defensive response.
- - Researchers tested 60 people, measuring heart activity while some completed a visual task after hearing a scary noise, revealing that tasks increased the second heart response component and decreased blood pressure.
- - The results indicate that the initial heart response is influenced by the parasympathetic (calming) system, while both sympathetic (activating) and parasympathetic systems play roles in the second response, suggesting the task affects how we react to threats based on our attention.
Helping you helps me: Beneficial effects of regulating others' emotions on well-being and physiological stress.
Emotion
December 2024
Rady School of Management, University of California, San Diego.
Improving others' emotions is cognitively and emotionally demanding, potentially increasing stress levels and decreasing well-being. However, the opposite could also occur: Attempts at improving others' emotions-that is, extrinsic interpersonal emotion regulation-could enhance regulators' affective well-being and shield against physiological stress because we theorize that engaging in regulatory action to improve others' emotions can strengthen relationships, activate self-regulation, and elicit prosocial reward. In two studies, we test the consequences on regulators when they help others regulate their emotions.

Previous research has demonstrated that hearing impairment is associated with heightened subjective experiences of listening effort, fatigue, and stress, impacting daily functioning. This study aimed to evaluate whether hearing impairment alters physiological stress systems and whether different aspects of hearing impairment could vary in predicting dysregulation in these systems. Hallmark measures of parasympathetic and sympathetic nervous system activity were derived from electrocardiography, impedance cardiography, and electrodermal activity recordings taken from 133 individuals, aged 37 to 73, over two 24-hr periods, including sleep.

This experiment (N = 113) tested whether personal choice vs. external assignment of task characteristics moderates the effect of incidental affective stimulation on effort-related cardiovascular response in a "do your best" task context. When participants could choose themselves the color of the stimuli (i.

The significance of physiological regulation in relation to behavioral and emotional regulation is well documented, but primarily in economically advantaged contexts. Few studies have been conducted in low- and middle-income countries. We investigated the feasibility and reliability of measuring autonomic nervous system (ANS) activity and behavior during challenge tasks in 30 children aged 8-10 years in Ghana during two visits, 1 week apart.
