Social anxiety and sensitivity to social-rank features in male faces.

Background And Objectives: Evolutionary theories propose that socially anxious individuals are especially sensitive to social-rank signals, presumably at the expense of the attunement to signals of affiliation. Despite this theoretical claim, few empirical attempts examined the association between social anxiety (SA) and sensitivity to specific features of social-rank and affiliation. This study aims to fill this gap.

Parents' involvement in the human papillomavirus vaccination decision for their sons.

Objectives: Parents are critical to ensure sufficient human papillomavirus (HPV) vaccine coverage. No studies to date have examined how mothers and fathers perceive their own, their partners' and their sons' involvement in HPV vaccination decision-making process.

Methods: An online survey methodology was used to collect data from a national sample of Canadian parents (33% fathers, 67% mothers, M=44) who had a 9-16years old son (n=3117).
