Study title

The data set contains preprocessed body sway (in mm) and heart rate (in beats-per-minute) data at ages 14 and 17, as well as raw data of life events (assessed at ages 2.5, 5, and 17), state anxiety (assessed at ages 14 and 17), participants’ height (at age 17), and attachment (assessed at 15-months of age). This data was used for analyses in the research described in the Frontiers in Behavioral Neuroscience paper by Niermann et al. (2018). The current study tested the stability of freezing-like behavior in a prospective longitudinal study investigation, following 75 adolescents from mid to late adolescence. To assess adolescents’ freezing behavior, we used a well-established method combining electrocardiography (heart rate) and posturography (body sway) in response to emotional picture-viewing of angry, happy, and neutral faces. A full description of the procedure and the measures is given in the Methodology file. The R-syntax files contain a description of data as well as all steps of data analysis that were performed. The results of those analyses are described in the paper.
