Biography

Dr. Hubbard and her students in the Peer Relations Laboratory are conducting four inter-related projects:

Understanding and Improving Children’s Bystander Behavior to Bullying: Dr. Hubbard and her students have conducted an implementation and evaluation of a bullying prevention program in Delaware schools, while simultaneously investigating why children do and do not intervene in bullying episodes. Sub-projects include: a) assessing factors that increase teacher implementation of the program, and b) investigating factors impacting children's bullying intervention, including empathy, conversations with parents about bullying, and group norms for intervention. 

Predicting Middle Childhood Peer Outcomes from Infant Attachment: Dr. Hubbard and her students are collaborating with Dr. Dozier and the Infant-Caregiver Project to investigate the peer relations outcomes of children who received the Attachment and Bio-Behavioral Catch-Up program in infancy. Peer relations outcomes assessed in this project include video-based measures of children's social information processing, playgroups to quantify children's social interactions, and a video game to assessment of children's reactive and proactive aggression.

Investigating Reactive and Proactive Aggression in Middle Childhood: Dr. Hubbard and her students are examining the reactive and proactive functions of aggression, with a particular focus on children's anger in response to peer provocation. Recent emphases have included a) assessing children's psychophysiology in-the-moment as they engage in reactive versus proactive aggression, b) investigating the temperamental qualities underlying the subtypes of aggression, and c) investigating the overlap-versus-distinctiveness of reactive and proactive aggression in comparison to callous-unemotional traits. 

Exploring Peer Victimization and Peer Rejection: Dr. Hubbard and her students are investigating the precursors, outcomes, and types of peer victimization and peer rejection in middle childhood. Sub-projects include: a) the multiple forms of peer victimization, b) internalizing problems in peer-victimized and peer-rejected children, c) the role of obesity in peer victimization, and d) the role of teachers in children's peer rejection and victimization.
