Computing the uncomputable; or,The discrete charm of second-order simulacra

We examine a case in which non-computable behavior in a model is revealed by computer simulation. This is possible due to differing notions of computability for sets in a continuous space. The argument originally given for the validity of the simulation involves a simpler simulation of the simulation, still further simulations thereof, and a universality conjecture. There are difficulties with that argument, but there are other, heuristic arguments supporting the qualitative results. It is urged, using this example, that absolute validation, while highly desirable, is overvalued. Simulations also provide valuable insights that we cannot yet (if ever) prove.     

Good vibrations: Analytic process as coupled oscillations

This paper develops a new model for the action of psychoanalysis based on concepts from non-linear dynamics (chaos theory and complexity theory). It shows that the analyst–analysand couple may be conceptualized as a new configuration with its own properties that promote complex development in both members of the couple. These developments are an emergent result of the formation of the analyst–analysand couple and are significantly independent of the particular content of the manifest interaction of the couple. The well-studied phenomena of coupled oscillators suggest the specific features of the analysand–analyst interaction that are likely to be most important in conceptualizing analytic change. The model has substantial clinical applications since efforts to arrange for a coupled oscillator system that is central to it are distinct from many of the traditional considerations associated with creating an analytic situation.     

Being seen or being watched? A psychoanalytic perspective on body dysmorphia

The focus of this paper is on individuals who present as excessively preoccupied with their body, perceiving some aspect(s) to be 'ugly' such that they feel compelled to alter and/or conceal this 'ugly' body part. These difficulties are understood as symptoms of an underlying narcissistic disturbance. The author suggests that the relative pervasiveness of an identification with a 'super'-ego accounts for the degree of severity of the disturbance (increasing the compulsion to alter and/or conceal the hated body part) and that it has implications for the patient's accessibility in analytic treatment. Understanding the vicissitudes of the development of the body–self in the context of the earliest relationship with the 'object of desire' is core to helping these patients because of the quality of the identifications that ensue and that are then enacted the transference.     

The role of beliefs in goal dynamics: prolegomena to a constructive theory of intentions

In this article we strive to provide a detailed and principled analysis of the role of beliefs in goal processing—that is, the cognitive transition that leads from a mere desire to a proper intention. The resulting model of belief-based goal processing has also relevant consequences for the analysis of intentions, and constitutes the necessary core of a constructive theory of intentions, i.e. a framework that not only analyzes what an intention is, but also explains how it becomes what it is. We discuss similarities and differences between our approach and other standard accounts of intention, in particular Bratman’s planning theory. The aim here is to question and refine the conceptual foundations of many theories of intentional action: as a consequence, although our analysis is not formal in itself, it is ultimately meant to have deep consequences for formal models of intentional agency.     

Framing Foreign Policy Alternatives in the Inner Circle: President Carter, His Advisors, and the Struggle for the Arms Control Agenda

This article examines strategic framing efforts within the president's inner circle of foreign policy advisors. The comparative case study method is used to describe and explain the framing process involved in President Jimmy Carter's arms control decisions with respect to the Soviet Union. Carter's two central foreign policy advisors, National Security Advisor Zbigniew Brzezinski and Secretary of State Cyrus Vance, portrayed the Soviets in very different terms. The premise underlying this study is that advisors attempt to frame their policy preferences favorably in order to influence the group process and the president's policy choice. Advisors do so by playing up the positive aspects of an option and downplaying any negative aspects. Three components of the framing process are explored: historical/cultural symbolism, personal beliefs and values, and political cost assessments.     

The Making of Female Presidents and Prime Ministers: The Impact of Birth Order, Sex, of Siblings, and Father-Daughter Dynamics

Although research into the factors that may affect male achievement of political leadership is relatively robust, very few studies on the making of female presidents and prime ministers exist. This paper examines the literature on birth order, sex of siblings, and parent-daughter dynamics to see whether the findings for male political leaders—that first-born individuals will be overrepresented as compared with later-born siblings—also hold for female ones. Two other hypotheses were tested concerning differences in birth order and sex of siblings between female political leaders and a larger sample of women. A review of the literature on parent-daughter dynamics suggests that this may be another important variable for future research into explanations for the success of women who achieve senior-level positions of power. The findings suggest that first-born women, like first-born men, are overrepresented among political leaders; that first-born women are overrepresented among female political leaders as compared with their numbers in a larger sample population; and that fewer female political leaders have an older brother than would be expected to occur in a larger sample population. The last finding applies only for women who come to power in the period 1960–1989, not those who gained office more recently.     

Applying linear systems analysis to dynamic behavior

In this paper we present an abbreviated discussion of the linear systems analysis in the time domain. We then consider the qualitative character of the behavioral dynamics predicted using the linear form of the analysis. The analysis is then extended to a second-order form. We illustrate some relevant new features introduced by the second-order form with a special case example.     

Order and chaos in fixed-interval schedules of reinforcement

Fixed-interval schedule performance is characterized by high levels of variability. Responding is absent at the onset of the interval and gradually increases in frequency until reinforcer delivery. Measures of behavior also vary drastically and unpredictably between successive intervals. Recent advances in the study of nonlinear dynamics have allowed researchers to study irregular and unpredictable behavior in a number of fields. This paper reviews several concepts and techniques from nonlinear dynamics and examines their utility in predicting the behavior of pigeons responding to a fixed-interval schedule of reinforcement. The analysis provided fairly accurate a priori accounts of response rates, accounting for 92.8% of the variance when predicting response rate 1 second in the future and 64% of the variance when predicting response rates for each second over the entire next interreinforcer interval. The nonlinear dynamics account suggests that even the “noisiest” behavior might be the product of purely deterministic mechanisms.     

Coming together and remaining a part: Development of a group-as-a-whole compass. Part II

Group-as-a-whole theory is an attempt to explain the collaboration and synergy that results when patients share their care. The art and science of treating individuals within psychotherapy groups is enriched by an understanding of the unique mediums ³ through which a group comes into being and the more general domains within which it comes to be known. This paper continues the development of a group-as-a-whole compass, as an integration of extant models and theories (Ettin, 1996). The focus shifts from conceptual and spatial models to an exploration of the cultural and relational processes that make up whole-group functioning. The paper comes full circle with hypotheses drawn about how a psychotherapy group, as a holistic phenomenon, is composed and maintained.Private practice, East Brunswick, New Jersey.     

The relation between rumination and temporal features of emotion intensity

Intensity profiles of emotional experience over time have been found to differ primarily in explosiveness (i.e. whether the profile has a steep vs. a gentle start) and accumulation (i.e. whether intensity increases over time vs. goes back to baseline). However, the determinants of these temporal features remain poorly understood. In two studies, we examined whether emotion regulation strategies are predictive of the degree of explosiveness and accumulation of negative emotional episodes. Participants were asked to draw profiles reflecting changes in the intensity of emotions elicited either by negative social feedback in the lab (Study 1) or by negative events in daily life (Study 2). In addition, trait (Study 1 & 2), and state (Study 2) usage of a set of emotion regulation strategies was assessed. Multilevel analyses revealed that trait rumination (especially the brooding component) was positively associated with emotion accumulation (Study 1 & 2). State rumination was also positively associated with emotion accumulation and, to a lesser extent, with emotion explosiveness (Study 2). These results provide support for emotion regulation theories, which hypothesise that rumination is a central mechanism underlying the maintenance of negative emotions.
