The interplay of personality and social relationships is as fascinating as it is complex and it pertains to a wide array of largely separate research domains. Here, we present an integrative and unified framework for analysing the complex dynamics of personality and social relationships (PERSOC). Basic principles and general processes on the individual and dyadic level are outlined to show how personality and social relationships influence each other and develop over time. PERSOC stresses the importance of social behaviours and interpersonal perceptions as mediating processes organized in social interaction units. The framework can be applied to diverse social relationships such as first encounters, short-term acquaintances, friendships, relationships between working group members, educational or therapeutic settings, romantic relationships and family relationships. It has important consequences for how we conceptualize, understand, and investigate personality and social relationships.

Using a dyadic design, this longitudinal study with 85 couples examined whether the stress buffering effect of optimism is due to an actual higher availability of social support or to positive illusions about available social support by taking simultaneously the recipients' and the providers' perspective on social support into account. At baseline, optimism and social support from the recipients' and the providers' perspective were assessed. Perceived stress was measured at 3 months follow‐up. Actor–Partner Interdependence Models showed that optimism was prospectively related to lower stress. Social support from the recipients', but not from the providers' perspective, partially mediated this relationship. The results suggest that optimists hold positive illusions about available support and that these illusions account at least partly for the stress buffering effect.

The present online-questionnaire study examined two fundamental social behaviors, social curiosity and gossip, and their interrelations in an English (n = 218) and a German sample (n = 152). Analyses showed that both samples believed that they are less gossipy but more curious than their peers. Multidimensional SEM of self and trait conceptions indicated that social curiosity and gossip are related constructs but with different patterns of social functions. Gossip appears to serve predominantly entertainment purposes whereas social curiosity appears to be more driven by a general interest in gathering information about how other people feel, think, and behave and the need to belong. Relationships to other personality traits (N, E, O) provided additional evidence for divergent validity. The needs for gathering and disseminating social information might represent two interlinked but different drives of cultural learning.

Abstract. At a broad level, the Konstanz Health Psychology research group aims at understanding the judgment and decision making processes underlying health-relevant behaviors. Towards this goal, several more specific research agendas are addressed. A primary aim is to understand the transition from knowing about risks to personally feeling at risk. In particular, we study the reception of relevant personalised health feedback such as feedback on cholesterol levels or blood pressure. Contrary to the dominant models of biased reasoning, our results on feedback reception suggest that people respond adaptively to health risk feedback. Furthermore, we study changes in the perception of health risk across time and their associated effects on the onset, maintenance, and cessation of health-relevant behaviors. In current research, we try to utilize methods from affective neuroscience for assessing affective and intuitive processes relevant to personal feelings of risk. These efforts are motivated by the broader goal of developing theoretical frameworks that can be applied across a range of behavioral domains. Key words: risk perception, health behavior change, reception of feedback The health psychology research group at the University of Konstanz is interested in the judgment and decisionmaking processes underlying health-relevant behaviors. A main goal is to understand the transition from knowing about risks to personally feeling at risk. Furthermore, the perception of health risks is a dynamic phenomenon. Thus, we aim to understand dynamic changes in risk perception and their associated effects on the onset, maintenance, and cessation of health-relevant behaviors. These efforts are motivated by the broader goal of developing theoretical frameworks that can be applied across a range of behavi oral domains.
