Personality constructs were proposed to describe intraindividual variability in interpersonal behavior. Flux refers to variability about an individual's mean score on an interpersonal dimension and was examined for the 4 poles of the interpersonal circumplex. Pulse and spin refer to variability about an individual's mean extremity and mean angular(More)
A person's behavior across situations can be characterized in terms of a mean level (disposition), a dispersion within the person around that mean level, and a stable organization to the pattern of dispersion (signature). The authors' goals were to examine the structure and stability of behavior, both at the level of behavioral dispositions and at the level(More)
In monkeys increasing serotonin function enhances affiliative interactions and promotes the acquisition of dominance. To examine whether similar effects occur in humans, we treated 98 subjects for 12 days with the serotonin precursor tryptophan (1g TID) and for 12 days with placebo in a double-blind, cross over study. Agreeableness/quarrelsomeness and(More)
OBJECTIVE We hypothesized that increasing brain serotonin in healthy individuals with high scores on 2 self-report measures of trait quarrelsomeness would reduce quarrelsome behaviours and enhance agreeable behaviours when measured ecologically using an event-contingent recording method. METHODS We conducted a double-blind crossover study, in which(More)
Evolutionary accounts of vulnerability to depression have focussed either on the attachment system (Bowlby, 1980) or the social rank system (Gilbert, 1992; Price, 1972). According to a two-factor evolutionary model, depression-prone dependent and self-critical individuals suffer from insecurities regarding both attachment and social rank, but they differ in(More)
The relative strength of both affective state and the personality trait neuroticism in predicting common physical symptoms was tested. The authors used an event-sampling design to overcome methodological limitations of past research in the area. Contrary to much previous research, neuroticism was found to be unrelated to reports of physical symptoms,(More)
The influence of context on interpersonal complementarity was examined using an event-contingent recording procedure. Setting and role status moderated the relation between how a person behaved and how the other person behaved. Individuals were more likely to respond with agreeable behavior to agreeableness in others when not at work than when at work and(More)
Theorists since D. Bakan (1966) have advocated the importance of mitigation for successful adaptation within the interpersonal domain. Although mitigation has previously been conceptualized as a balance between agency and communion (interdimensional mitigation), the circumplex framework suggests that mitigation may also be conceptualized as a balance within(More)
Bright light is used to treat winter depression and might also have positive effects on mood in some healthy individuals. We examined possible links between bright light exposure and social interaction using naturalistic data. For 20 days in winter and/or summer, 48 mildly seasonal healthy individuals wore a light meter at the wrist and recorded in(More)
Personality constructs are typically conceptualized as central tendencies of the individual. We explore whether dynamic personality constructs that quantify the within-individual variability of behavior across situations and over time predict the closeness of social relationships. We focused on interpersonal spin, defined as the degree of dispersion in a(More)
