Abstract

Despite substantial evidence indicating that relationships shape people’s self-concept, relatively little is known about how people reorganize their sense of self when relationships end and whether this varies as a function of people’s beliefs about relationships. In this report, we examine the prospective association between self-report adult attachment style and self-concept recovery among 89 adults following a recent marital separation. People high in attachment avoidance are characterized by the tendency to deactivate (i.e., suppress) painful attachment-related thoughts and feelings, and, following Fagundes, Diamond, and Allen (2012), we hypothesized that highly avoidant people would show better or worse self-concept outcomes depending on their ability to successfully regulate their emotional experience during a divorce-related mental recall task. We operationalized self-regulation using respiratory sinus arrhythmia (RSA) and found that highly avoidant people who showed RSA increases across our divorce-related mental activation task (DMAT) evidenced improvements in their self-concept over three months. In contrast, highly avoidant adults who showed RSA decreases during the DMAT showed no improvement (or a worsening) in their self-concept disruptions over the subsequent three months. These results suggest that RSA, an index of heart rate variability, may provide a window into self-regulation that has the potential to shed new light on why some people cope well or poorly following the loss of a relationship. Discussion centers on the potential mechanisms of action that explain why some people are able to successfully deactivate attachment-related thoughts and feelings whereas other people are not.

Abstract

Coping with pressure and anxiety is an ineluctable demand of sports performance. Heart rate variability (HRV) Biofeedback (BFB) shall be used as a tool for self regulating physiological responses resulting in improved psycho physiological interactions. For further analysis, the present study has been designed to examine the relationship between anxiety and performance and also effectiveness of biofeedback protocol to create stress-eliciting situation in basketball players. Thirty basketball players of university level and above (both male and female) aged 18-28 years, who scored a minimum of 20 in state trait anxiety inventory, were randomly divided into three equal groups- Experimental (Biofeedback) group, Placebo group and Control (No Treatment) group. The BFB group received HRV BFB training for 10 consecutive days for 20 min that included breathing at individual’s resonant frequency through a pacing stimulus; Placebo group was shown motivational video clips for 10 consecutive days for 10 min, whereas No Treatment Control group was not given any intervention. Two way repeated measure ANOVA was applied to analyze the differences within and between the groups. Anxiety, coping self-efficacy, heart rate variability, respiration rate, and performance (dribbling, passing and shooting) at session 1, 10 and 1 month follow up were statistically significant in each group along with interaction of group and time (p < 0.001). Also, all the measures showed statistically significant inter group difference (p < 0.05). The findings are harmonious with existing data on HRV BFB as a strategy for dealing with anxiety. The Placebo group showed improvement in self efficacy and performance post training. The Control group showed no change in any variable except performance. The results of the study support the idea that HRV BFB lowers the anxiety and thus there seems to be a potential association between HRV BFB and performance optimization.
