Anxiety and counter-conditioning: the role of the behavioral inhibition system in the ability to associate aversive stimuli with future rewards

A total of 130 female undergraduates performed a counter-conditioning choice-task. This task presented two response alternatives and subjects were instructed to earn the maximum number of points. Responses to button 1 were normally followed by an immediate reward (an average gain of 7.5 points). Responses to button 2 were always followed by a punishment (an average loss of 20 points), but caused the next-but-one press on button 1 to give an average gain of 115 points. Thus, subjects were required to learn and maintain this counter-conditioning association. Four groups of subjects were formed according to the scores on the Sensitivity to Punishment and Sensitivity to Reward scales (which are measures of individual differences of Gray's anxiety and impulsivity personality dimensions, respectively). A 69.2% of subjects learned and maintained the counter-conditioning association. As predicted, personality results confirmed that subjects with lower scores on the Sensitivity to Punishment scale learned the counter-conditioning association better and faster when compared with high scorers. Results are consistent with Gray's Behavioral Inhibition System (BIS) model of anxiety which holds that individual differences in anxiety may relate to the ability to associate aversive stimuli with a future reward. Assuming that anxiety depends on BIS functioning, our results show that high trait anxious subjects, if compared with low anxious ones, would have a lower ability for associating an aversive event with a later appetitive one. This learning process would serve non-anxious subjects to reduce the aversiveness of cues of punishment and to cope better with stressful situations.

Generosity: a psychological and interpersonal motivational factor of therapeutic relevance

This paper examines the role of generosity in analysis. Generosity represents a complex constellation of cognitions and affects that is antithetical to those states of super-ego harshness that characterize many forms of human psychopathology. In development, generosity is evoked by idealization, and a dynamic axis of idealization-generosity promotes relational proximity between the child and its caretakers, and eventually fosters separation and individuation. Generosity is highly sensitive to adverse conditions, and requires environmental conditions that are conducive to psychosomatic well-being. The imaginal basis of generosity is rooted in the myth of the 'hero and the return', which is the mythic foundation of the analyst's role as psychopomp. It is argued that the generosity of the analyst is a cardinal therapeutic factor in treatment.     

Why Don't Continents Move? Why Don't People Change?

People don't change because they can't, don't want to, don't know how, or don't know what to change. The transtheoretical model provides an integ-rative model for understanding reasons for not changing, as well as readiness to change. Stages and levels of change guide therapists in their work in helping clients change. Clients in the precontemplative stage typically cannot change without special help. Those in the contemplation stage are not sure they want to change. Those in the preparation stage are afraid they do not know how to successfully change. The levels of change help guide therapists and clients on what to change.     

Discovery algorithms for hierarchical relations

Two algorithms based on a latent class model are presented for discovering hierarchical relations that exist among a set ofK dichotomous items. The two algorithms, stepwise forward selection and backward elimination, incorporate statistical criteria for selecting (or deleting) 0–1 response pattern vectors to form the subset of the total possible 2 ^k vectors that uniquely describe the hierarchy. The performances of the algorithms are compared, using computer-constructed data, with those of three competing deterministic approaches based on ordering theory and the calculation of Phi/Phi-max coefficients. The discovery algorithms are also demonstrated on real data sets investigated in the literature.     

Values education in a democratic society

A democratic society requires a degree of consensus on values. But it is argued that the model of values education as the transmission of certain predetermined values is inadequate in a democracy, since for several reasons the transmission of predetermined values can itself be undemocratic. Education for individual autonomy in matters of values is also, by itself, inadequate. Each generation needs the resources by which it can work out its own interpretation of democratic values. What is also needed, then, is an education in a common language of discourse — which can be drawn primarily from philosophy — which will facilitate public debate.     

Data, model, conclusion, doing it again

This paper explores the robustness of conclusions from a statistical model against variations in model choice (rather than variations in random sampling and random assignment to treatments, which are the usual variations covered by inferential statistics). After the problem formulation in section 1, section 2 presents an example from Box and Tiao in which variation in parent distribution is modeled for a one sample location problem. An adaptive Bayesian procedure permits to use a weighted mixture of parent distributions rather than choosing just one, such as a normal or a uniform distribution.In section 3 similar considerations are applied to an event history model for the influence of education and gender on age at first marriage, but here the conclusions are hardly influenced by the choice of the duration distribution. In section 4 a brief discussion of model choice in factor analysis and structural equation models is followed by a more elaborate treatment of the choice of integer valued slopes for item response functions in the OPLM model which is an extension of the Rasch model. A modest simulation study suggests that Adaptive Bayesian Modeling with a mixture of sets of slopes works better than fixing one set of postulated slopes.The paper concludes with some remarks on the roles and sources of prior distributions followed by a short epilogue which argues that simultaneous consideration of a class of models for the same data is sometimes superior to exclusively analyzing the data under one specific model chosen from such a class.This article is based on the Presidential Address Ivo W.

Neuroticism,coping and change in MCMI-II clinical syndromes: test of a mediator model

The aim of the study was to examine prospectively whether coping mediated the relation between Neuroticism and change in different clinical mental syndromes. Assessments were conducted with 154 former psychiatric outpatients six and seven years after their initial contact with an outpatient clinic. Dispositional coping mediated the relation between Neuroticism and change in four of the nine clinical scales of the Millon Clinical Multiaxial Inventory (MCMI-II) (Millon, 1987). High Neuroticism led to coping strategies of disengagement and the venting of emotions and to a lack of problem-focused coping, which in turn translated into a relative increase on the MCMI-II scales. The mediator model of coping was found to apply to the MCMI-II scales "somatoform disorder’, ‘dysthymia’, ‘alcohol dependence’ and ‘thought disorder’. Results are discussed under the perspective of an integration of the positions of the transactional theory of stress and personality psychology. .     

The Spiritual Task of Religion in Culture: An Evolutionary Perspective

It is quite impossible to consider human nature within an evolutionary perspective if we leapfrog over culture and establish some direct relation between cosmic and human evolution without taking culture into consideration. Culture holds a significant place within the structures of nature, as the "epic" of evolution portrays nature—cosmic, physical, and biological. Religion emerges within culture, and it plays a role in organizing the human consciousness and in generating the stories, rituals, and morality that constitute the organization of consciousness. Since organization of consciousness determines how culture is conducted, and since we face a global crisis today because of the ways we are conducting our culture, religion's role is critical for the future of culture. Wherever it is attempted, whether in terms of traditional or posttraditional modes, the fashioning of adequate worldviews, rituals, and morality is an essentially religious activity. For both traditional and posttraditional modes, the task is to weave structures of meaning with the sciences of evolution so as to effect the most suitable organization of consciousness.     

The Epic of Evolution: A Course Developmental Project

The Epic of Evolution is a course taught at Northern Arizona University. It engages the task of formulating a new epic myth that is based on the physical, natural, social, and cultural sciences. It aims to serve the need of providing meaning for human living in the vast and complex universe that the sciences now depict for us. It is an interdisciplinary effort in an academic setting that is often divided by specializations; it focuses on values in a climate of relativism; and it concentrates on an enterprise for which there are few textbooks at hand. The course is presented in three segments: the cosmos before humans appeared, the human phenomenon, and scenarios for the future of evolution.
