The Use of Rumination and Reappraisal in Adolescents Daily Life: Links to Affect and Emotion Regulation Style.

This study explored the association between temperament-i.e., positive affect (PA) and negative affect (NA)-and emotion regulation (ER), and what momentary factors influence the selection of rumination or reappraisal during adolescents' daily life.

Adolescents' Positive Cognitive Emotion Regulation Predicts Heart Trajectories During a Mother-Adolescent Conflict Interaction.

This paper aimed to (a) validate a novel technique that quantifies the length of the trajectories the cardiac system follows within a two-dimensional state-space, and (b) test its usefulness to better understand how cognitive emotion regulation (CER) style is associated with cardiac output. A positive CER style was assessed in a sample of healthy adolescents (n = 57), and mean and total distances, in addition to heart rate variability (HRV) measures and cardiac entropy (SampEn), were calculated during a conflict discussion with the adolescents' mothers. Associations between distances and HRV measures in time and frequency-domains and SampEn were examined to better understand the physiological meaning of distances; further, whether a positive CER style would predict distances, HRV, and SampEn.

Emotion Regulation Style and Daily Rumination: Potential Mediators between Affect and Both Depression and Anxiety during Adolescence.

Adolescence is a vulnerable period for depressive and anxious symptom development, and emotion regulation (ER) may be one mechanism linking temperament-i.e., positive affect (PA) and negative affect (NA)-with such symptomatology.

Adolescents at risk of anxiety in interaction with their fathers: Studying non-verbal and physiological synchrony.

Adolescence is a vulnerable period in terms of the onset of anxiety disorders, and dyadic parent-adolescent interactions may play a key role in either increasing or reducing the risk of psychopathologies. This study examines the presence of physiological synchrony (specifically, linkage in interbeat interval series) and non-verbal synchrony in positive and negative interactions between adolescents (aged 13-16) and their fathers. Non-verbal synchrony was quantified through the coordination of the interactants' body movements, using an automated video-analysis algorithm (motion energy analysis).
