Description
This study examines the relations among three aspects of temperament (shyness, impulsivity, and effortful control), resting respiratory sinus arrhythmia (RSA) recorded during a calming film and RSA suppression during three behavioral measures of effortful control, and adjustment (anxiety and externalizing behavior) in a sample of 101 preschool-age children. Principal components analysis was used to create composites for effortful control, shyness, impulsivity, anxiety, and externalizing behavior, and hierarchical regression analysis was used to test the study hypotheses. As expected, baseline RSA was negatively related to effortful control in shy children, but was unrelated to effortful control in children who were not shy. It was hypothesized that high baseline RSA would reduce the relation between shyness and anxiety, and between impulsivity and externalizing behavior; this hypothesis was supported for externalizing behavior, but not for anxiety. The interaction between impulsivity and RSA as a predictor of externalizing was statistically independent of effortful control, indicating that these are unique effects. Finally, it was hypothesized that RSA suppression would be positively related to effortful control for children low, but not high, in shyness. There was a marginal interaction between shyness and RSA suppression, with RSA suppression marginally negatively related to EC for children low in shyness, but unrelated to effortful control for children high in shyness; the direction of this association was opposite predictions. These findings indicate that RSA is more strongly related to effortful control for children high in shyness, and that it consequently may not be appropriate to use RSA as an index of EC for all children. This study also draws attention to the need to consider the context in which baseline RSA is measured because a true baseline may not be obtained for shy children if RSA is measured in an unfamiliar laboratory context. The finding that high RSA moderated (but did not eliminate) the relation between impulsivity and externalizing behavior is consistent with the conceptualization of RSA as a measure of self-regulation, but further research is needed to clarify the mechanism underlying this effect.

Description
Although researchers often conceptualize shyness as stable across different situations (e.g., Rubin, Coplan, & Bowker, 2009), evidence has suggested that shyness may consist of situation-specific components (e.g., Asendorpf, 1990a; 1990b; Gazelle & Faldowski, 2014; Xu & Farver, 2009). This study was aimed at developing a systematic measurement tool for situational shyness in adolescence, as well as examining the relations between situational shyness and other popular measures of shyness and between situational shyness and adjustment. A sample of Chinese adolescents (N = 492) from an urban school participated in the study during 7th (T1) and 8th (T2) grades. Adolescents self-reported their situational shyness using a new measure of hypothetical scenarios, as well as their general shyness, anxious shyness, regulated shyness, depressive symptoms, and loneliness. Peers reported adolescents’ general and conflicted shyness, and popularity and peer rejection. The school provided records of their academic achievement (exam scores).
Exploratory and confirmatory factor analyses of the situational shyness measure consistently supported that shyness in the hypothetical scenarios can be separated into three components: shyness with familiar peers, shyness with unfamiliar peers, and shyness in formal situations. These components had differential associations with other measures of shyness. Self-reported general and anxious shyness were related consistently to shyness with unfamiliar peers and in formal situations, and occasionally to shyness with familiar peers. Self-reported regulated shyness was not related to self-reported shyness in any situation. Peer-reported conflicted shyness was associated with shyness with familiar and unfamiliar peers, whereas peer-reported general shyness was associated with shyness with unfamiliar peers and in formal situations. Moreover, situational shyness showed differential relations to maladjustment. Shyness with familiar peers was associated positively with maladjustment in multiple domains, especially academic and peer difficulties. Shyness with unfamiliar peers and shyness in formal situations, in contrast, were associated primarily with internalizing problems. In addition, shyness with unfamiliar peers and in formal situations occasionally related to positive adjustment, suggesting shyness in specific situations may still be protective in contemporary urban China. The findings provided new evidence that the correlates of shyness depend on the situation in which shyness occurs, and may inform future intervention programs.
