My research interests are in the area of close relationships, with specific interests on the topics of social self-regulation, social perceptions and beliefs, and social support seeking. Typically each student that works with me carves out some unique topic within the area of close relationship processes, as you can see below.
A primary area of my research involves the study of how people regulate their thoughts and behaviors in their social interactions with others, including friends, family members, romantic partners, and strangers. Johanna Peetz and I studied the factors that predict people’s ability to keep promises of change to their romantic partners (Peetz & Kammrath, 2013). Megan McCarthy and I studied the factors that impact a person’s likelihood to speak up about relational dissatisfactions (McCarthy & Kammrath, in prep). We also studied how different personality traits predict assertiveness within a close relationship in low versus high importance situations (Kammrath, McCarthy, Friesen, & Cortes, under review). Kassandra Cortes and I studied what happens when you take a typical self-regulation task and frame it as a task that benefits another person, that is, make it a social action instead of a personal action (Cortes, Kammrath, Scholer, & Peetz, 2013). Annie Locke and I studied how self-control depletion predicts the level of mindfulness (mindful attention) that people give to romantic partners (Locke, Kammrath, & Armstrong, in prep). Julia Brinton and I studied how psychological strains at work (negative affect and exhaustion) predict people’s failures to inhibit hostile responding at home (Brinton, Kammrath, & Wayne, in prep).
Seeking Social Support as an Emotion Regulation Strategy
A relatively new area that I am interested in arose from recent work with Benjamin Armstrong. In his study, we examined the consequences associated with seeking a lot of support from one supporter versus the consequences of seeking support from many different supporters (Armstrong & Kammrath, in press). We further investigated the tactics people use to decide whether to approach supporter A versus supporter B and what outcomes result from such choices (Kammrath, Armstrong, & Iida, in prep). In follow-up research, Katelyn McNab is investigating whether people use different tactics about which supporters to approach if they have done some self-soothing before they seek social support.
Social Perceptions and Beliefs
Another area of my research involves the study of how people judge one another’s personalities, attitudes, motivations, etc., as well as the consequences of these judgments. Abigail Scholer and I investigated whether certain kinds of positive impressions are lost more easily than others when perceivers see a few examples of behavior that goes against the original impression (Kammrath, Ames, & Scholer, 2007). We also investigated whether highly agreeable individuals show a halo-effect for all types of impressions, as was previously thought, or whether they show “pitchfork” effects for certain types of behavioral observations, e.g. mean behavior (Kammrath & Scholer, 2011). Johanna Peetz and I studied whether people’s general belief about whether people can change their personalities influences their responses to a romantic partner’s failed attempt to change (Kammrath & Peetz, 2012). Charity Friesen and I studied the interpersonal consequences of having accurate knowledge of a friend’s “trigger profile” – that is, information about which annoying interpersonal behaviors bother the friend more and less (Friesen & Kammrath, 2011). Julia Brinton, John Petrocelli and I studied what happens to a current relationship when a person has a potent upward counterfactual thought about a romantic interest from their past (Petrocelli, Kammrath, Brinton, Uy, & Cowens, under review).
