ABSTRACT Attentional network functioning in emotionally neutral conditions and self-reported attentional control (AC) were analysed as predictors of the tendency to engage in dysfunctional emotion regulation strategies. Diminished attentional orienting predicted an increased tendency to engage in brooding rumination, and enhanced alertness predicted a greater chance of suppression, beyond trait anxiety and self-reported AC, which were not predictive of either rumination or suppression. This is the first study to show that some forms of dysfunctional emotion regulation are related to the attentional network functioning in emotionally neutral conditions. Results are discussed in relation to regulatory temperament and anxiety-related attentional biases literature.
Research on electroencephalogram (EEG) asymmetries and anxiety proneness has recently spread to emotion regulation capabilities. We studied whether attentional control (AC), a temperamental construct related to emotional regulation, was associated with asymmetrical patterns of resting EEG activity at the frontal and parietal regions, reflected not only in the α frequency band (8-13 Hz) but also in higher bands β1 (13-20 Hz) and β2 (20-30 Hz). Self-reports of AC and trait anxiety, and resting EEG recordings, were obtained from 58 healthy participants. Correlational analysis showed that lower levels of self-reported AC were associated with less α, β1, and β2 powers in the left parietal cortex, while no significant relationships were found between the AC and EEG oscillations in the prefrontal cortex. The role of the left and right parietal lobes in the attentional processes is discussed.

Abstract: Effective regulation of emotions requires the ability to voluntarily manage attention, i.e. attentional control (AC), which has been related to heart rate variability and vagal tone in laboratory based research. In this study, we calculated the correlation dimension (CD), the fractal-like properties (scaling exponents ?1 and ?2, and fractal dimension) and the sample entropy of heart rate time series obtained from ECG recordings (4 hours long each) taken from a sample of healthy students (n=47) during everyday activities. AC was assessed through a self-reported questionnaire. As expected, a linear positive correlation was found between AC scores and CD and entropy, but no associations were found between AC and ?1 and fractal dimension. The association between AC and ?2 was negative and marginally significant. No associations were found between AC and linear heart rate variability measures. These results show that nonlinear measures of long, everyday life, heart rate time series may provide useful information about the AC ability of healthy students.

Several studies have reported differences in long-range temporal correlations of EEG oscillations between depressed and nondepressed individuals. The question remains unsolved whether these differences are also linked to negative emotion regulation strategies that configure a depressive style. In this study we applied detrended fluctuation analysis to the amplitude envelope of broad band and narrow band (theta and alpha) spontaneous EEG oscillations of a sample (N = 56) of young nondepressed adults to whom several emotion regulation and depression questionnaires were administered. Linear positive correlations between the scaling exponents of both broad band and theta band oscillations and negative emotion regulation strategies and depression scores were found. These results suggest that previously found differences between depressed and nondepressed individuals may exist before depression manifests, as differences could be linked to a negative emotion regulation style that in some cases could lead to the development of a depressive disorder.

The present study explores both resting cortical EEG asymmetry and vagally-mediated heart rate variability (HRV), as an index for vagal tone, as physiological correlates of self-reported attentional control in a sample of 53 healthy young adults. Regression analyses indicate that higher vagally-mediated HRV and lower right-sided parietal activity in the β2 frequency range (20 to 30Hz) are significant predictors of larger attentional control. Results are in line with some of the basic features of the neurovisceral integration model and stress the role of parietal areas in attentional control capabilities, thus aiming to consider attentional control as a trait-like disposition.

Introduction. The interplay of reactive and regulatory temperamental processes appears to be essential for a better understanding of emotional states and disorders. In this study we explored the prospective relationship between reactive temperament (negative affect), regulatory temperament (effortful control), negative emotion regulation styles (rumination and suppression) and self-recorded anxiety, worry, and avoidance in naturalistic conditions. Method. Thirty-two young adults were first assessed through questionnaires on negative affectivity, effortful control, and two forms of negative emotion regulation (rumination and suppression). After this they recorded anxiety, worry, and avoidance three times a day over 50 consecutive days through an on-line access electronic diary. Results. High levels of negative affect and low levels of effortful control were associated with higher levels of anxiety, worry, and avoidance (p<.01). The prospective association between negative affectivity and avoidance was moderated by effortful control (Total R2=.49). Moreover, the brooding facet of rumination totally mediated the association between negative affect and anxiety with a significant indirect effect (Effect=.30, Boot CI95%=.09 to .69). Conclusions. Avoidance patterns are significantly determined by negative affect – effortful control interaction and rumination, especially brooding, totally mediates the relationship between negative affect and anxiety.
