Personality, birth order and attachment styles as related to various types of jealousy

The relationships between jealousy, personality, attachment styles and birth order were examined in a sample of 100 Dutch men and 100 Dutch women. Three types of jealousy were examined: reactive jealousy (a negative response to the emotional or sexual involvement of the partner with someone else), preventive jealousy (efforts to prevent intimate contact of the partner with a third person), and anxious jealousy (obsessive anxiety, upset, and worrying about the possibility of infidelity of the partner). The three types of jealousy were not at all related to egoism and dominance, but significantly correlated with neuroticism, social anxiety, rigidity and hostility. Only among women was a low self-esteem correlated with jealousy. On all three jealousy measures, those with an anxious-ambivalent attachment style were more jealous than those with an avoidant style, with those with a secure attachment style being the least jealous. Attachment style was strongly related to most personality dimensions, but the effects of attachment style upon jealousy stayed virtually the same when controlling for personality factors. The most important finding in the present study was that laterborns were more jealous according to all three measures than firstborns, a finding that was not due to personality differences between first- and laterborns, nor to differences in attachment style, gender or occupational level of the father. Because some evidence was found that only borns were slightly less jealous than firstborns, it is suggested that the experience of exclusive love and attention in one's childhood, leads to a lower level of jealousy among firstborns.     

Prime Minister Leadership Styles in Foreign Policy Decision-Making: A Framework for Research

Although the institutional contexts of prime ministers in parliamentary democracies and of U.S. presidents are very different, both types of executive leaders influence the decision-making processes through their leadership styles. Leadership style includes how the leaders relate to those around them, how they like to receive information, and how they make up their minds. While there are numerous empirical studies and theoretical frameworks on the leadership styles of U.S. presidents, few studies of prime ministers are concerned with personality and styles of leadership. This paper reviews the literature on U.S. presidential styles and on organizational leadership in order to construct a framework for the study of prime minister leadership styles. Components of the proposed framework are illustrated with examples of British prime ministers and German chancellors. In addition, categories of dependent variables to be explained by leadership style are discussed. I argue that leadership style has the greatest impact on the decision-making process and that although the direct effect of leadership style on foreign policy behavior is less, leadership style indirectly influences foreign policy through the decision-making process.

Reactions to DMT as related to psychotic and borderline personality organization

Thirty-one inpatients in a psychiatric clinic were assessed with DMT and the Structural Interview. In order to assemble every relevant reaction that an individual might have to a percept-genesis, 130 DMT variables were formed. The results were first subjected to a quality control of the DMT-scores and then subjected to partial least squares in latent variables (PLS) discriminant analysis. The analysis showed that it is possible to separate patients with psychotic PO (PPO) from those with borderline PO (BPO) by means of the 130 variables. The BPO group is characterized by aggressive manifestations, sensitivity to threat, identity lability and various transformations of the Hero gestalt. The PPO group, on the other hand, is characterized by high threshold values for perception, lack of identity, denial and repression of the peripheral person at a late-phase level. There are other perceptual reactions that are important predictors of PO than the defence categories of the manual. These perceptual reactions do not correspond to the traditional psychodynamic defence mechanisms. Our conclusion is that principal component analysis (PCA) and PLS are useful methods of finding discriminating patterns of perceptual reactions to the DMT for patients with different PO.     

跟踪操作业绩与人格特征的关系

本研究发现,跟踪作业的业绩与允许误差值之间有某种规律性的关系。因此,跟踪任务的操纵器设计应考虑最佳宽容度。本文还探讨了不同人格维度与跟踪作业业绩之间的关系。就单个人格维度而言,内倾者的跟踪作业业绩优于外倾者;较高精神质者优于较低精神质者。在神经质维度上表现出高神经质者作业业绩好于低神经质者的倾向。     

Matching, maximizing, and hill-climbing

In simple situations, animals consistently choose the better of two alternatives. On concurrent variable-interval variable-interval and variable-interval variable-ratio schedules, they approximately match aggregate choice and reinforcement ratios. The matching law attempts to explain the latter result but does not address the former. Hill-climbing rules such as momentary maximizing can account for both. We show that momentary maximizing constrains molar choice to approximate matching; that molar choice covaries with pigeons' momentary-maximizing estimate; and that the “generalized matching law” follows from almost any hill-climbing rule.     

Understanding and Evaluating Bureaucratic Politics: The Nexus Between Political Leaders and Advisory

Bureaucratic politics—for example, the "political" interaction between individuals and organizations in the executive branch of government—is a potentially significant force affecting the course and outcomes of governmental policymaking processes. In this article, an empirical and normative model and operationalization of bureaucratic politics is developed, treating it as a variable rather than as an immutable (and by definition problematic) property of policy decision-making. A conceptual model, linking the nature and intensity of bureaucratic politics in advisory systems to the characteristics of the political leaders served by them, is also developed. On the basis of earlier studies of presidential leadership (e.g., Preston, 1996), the leader's need for power, cognitive complexity, and prior policy experience/expertise are hypothesized to affect the organization and operation of the advisory system in terms of bureaucratic politics. Using Hermann's (1983) Personality Assessment-at-a-Distance (PAD) coding technique, theoretical assertions are illustrated in a detailed case study of two critical episodes in U.S. decision-making in the conduct of the Vietnam war in 1965 and 1968.     

Basic Personality Inventory clinical and validity scales: Stability and internal consistency

A sample of 71 incarcerated adult male inmates was used to investigate the stability and internal consistency for the clinical and validity scales of the Basic Personality Inventoiy. One month test-retest stability coefficients for the clinical scales ranged from .53 to .77. KR-20 reliabilities ranged from .61 to .86 on each occasion. With the exception of the longer perseveration scales, stability was also reasonable for the validity scales. Overall, the Basic Personality Inventory clinical and validity scales demonstrated favorable stability and reliability in an inmate population.This research was supported by a STEP grant from the Alberta Government.
