Spontaneous Goal Inference (SGI)

When people learn about or observe the behaviors of others, they tend to make implicit inferences from these behaviors (e.g., Uleman, Saribay, & Gonzalez, 2008). Such inferences are an essential part of a person's ability to understand his/her environment and to prepare appropriate behavior within that environment. In the present paper, we review the conditions under which people are more likely to make implicit goal inferences versus implicit trait inferences. The distinction between these two ways of understanding the behavior we observe has important consequences for how we make predictions about future behavior, set expectations for our interaction partners, and how we choose to behave. It can determine when we stereotype. However, until now, the literature has focused on trait inference as the dominant way perceivers make sense of their environment, with little discussion of inferences concerning a person's goals.     

Effects of Acute Stress or Centrally Injected Interleukin-1beta on Neuropeptide Expression in the Immune System

Acute stress stimulates the expression and release of corticotropin-releasing hormone (CRH) and arginine vasopressin (AVP) from the hypothalamus, and the pro-opiomelanocortin products beta-endorphin and ACTH from the anterior pituitary. These neuropeptides are also expressed in immune tissues, and it has been proposed that they may modulate immune responses to stress through paracrine mechanisms. We subjected rats to restraint stress or central injection of interleukin (IL)-1beta to determine whether these acute stimuli can alter the expression of neuropeptides in the spleen and thymus. Restraint stress significantly increased the contents of all these neuropeptides in thymic, but not splenic, extracts. A single icv injection of IL-1beta increased contents of CRH, AVP, ACTH and beta-endorphin in the spleens of both sham-operated and adrenalectomised (ADX) rats. IL-1beta increased thymic contents of CRH and ACTH in sham-operated rats but these increases were not observed in ADX rats. These results suggest that the effects of IL-1beta on neuropeptide expression in the spleen are independent of glucocorticoids, whereas IL-1beta stimulation of neuropeptide expression in the thymus is dependent on circulating glucocorticoids. There were significant correlations between increases in CRH, ACTH and beta-endorphin in the spleen, and between CRH and ACTH in the thymus, consistent with the suggestion that IL-1beta-induced increases in ACTH and beta-endorphin may be mediated through CRH. These results provide evidence that stressors can directly influence neuropeptide expression in immune tissues. Thus stress may influence immune functions through paracrine mechanisms involving locally synthesised neuropeptides as well as through activation of the hypothalamo-pituitary-adrenal axis.     

Painting Group Portraits: Studying Life Outcomes for Aggressive and Withdrawn Children

Aggression and social withdrawal have long been of interest to personality psychologists. The present article presents a longitudinal study of the development of children selected from a community sample who were high on aggression and withdrawal. The selection of outcome variables is discussed, and outcomes during adolescence are described. For both males and females, high aggressiveness was predictive of low intelligence, poor school achievement, and psychiatric problems. For females, high aggressiveness was also predictive of general health problems. High social withdrawal was predictive of poor school achievement. Females who were high on withdrawal also had an elevated rate of abortions. Individuals who were high on both aggression and withdrawal had relatively poor social competence, had general problems with behavior, had low intelligence, and were performing poorly in school.     

Integrating dispositions, signatures, and the interpersonal domain

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 of behavioral signatures. Participants completed event-contingent records of their social interactions over a 20-day period. Participants recorded their own social behavior (dominant, agreeable, submissive, quarrelsome) in 4 situations defined by the perceived social behavior of their primary interaction partners (agreeable-dominant, agreeable-submissive, quarrelsome- submissive, quarrelsome-dominant). Findings suggest that (a) once the normative influences of situations on behavior are removed, the remaining behavioral variation reflects both consistent cross-situational differences between individuals (dispositions) and consistent situational differences within individuals (signatures); (b) both dispositions and signatures display a 2-dimensional structure in adherence to the interpersonal circle; and (c) both dispositions and signatures constitute stable aspects of personality functioning.     

Contextual influences on interpersonal complementarity

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 when in a high status work role relative to a low status work role. Reciprocity between dominance and submissiveness was found in work settings but not in nonwork settings. Individuals were more likely to reciprocate more submissive behavior by the other person with more dominant behavior and more likely to reciprocate more dominant behavior by the other person with relatively more submissive behavior when in a higher status work role relative to lower status work roles. Results were interpreted in terms of the influence of decreased structure and shared goals on increasing interpersonal complementarity.
