Effects of inflation on the subjective value of delayed and probabilistic rewards

In the years prior to 1994, there were very high rates of inflation in Poland, and the zloty depreciated relative to the U.S. dollar. However, the new zloty, introduced in 1995, was associated with greatly decreased rates of inflation and provided a more stable currency. We report a series of three experiments that take advantage of these changes to examine the effects of inflation on the subjective value of delayed and probabilistic rewards. Subjects were Polish citizens familiar with both zlotys and dollars. The first two experiments, conducted in 1994, used dollars and old zlotys, and the third experiment, conducted in 1996, used dollars and new zlotys. In all three experiments, the dollar and zloty rewards were of equivalent worth, according to the then current exchange rates. In Experiment 1, subjects chose between immediate and delayed rewards and, in Experiment 2, chose between certain and probabilistic rewards. The subjective value of a delayed reward was greater when its amount was specified in dollars than when it was specified in old zlotys. In contrast, the currency in which a reward was specified had no effect on the subjective value of probabilistic rewards. The results of these two experiments suggest a selective effect of inflation on decisions involving delayed rewards. This was verified in the third experiment, in which, using new zlotys, no differences in discounting were observed between the two currencies with either probabilistic or delayed rewards. Importantly, in all three experiments, the discounting of both delayed and probabilistic rewards was well described by the same simple mathematical model, suggesting that similar decision-making processes underlie both phenomena. However, the present results argue against a single-process theory in which the discounting of probabilistic rewards is derived from the discounting of delayed rewards.     

SPIRITUALITY AS A NATURAL PHENOMENON: BRINGING BIOLOGICAL AND PSYCHOLOGICAL PERSPECTIVES TOGETHER

Abstract. Working in Britain and in Poland, the authors independently arrived at an interpretation of spirituality as a natural phenomenon. From the point of view of the British author, spirituality is based on a biological predisposition that has been selected for in the process of evolution because it has survival value. In several important ways this approach is in harmony with the psychological perspective of the Polish author that sees spirituality as a socioculturally structured and determined attempt to cope with the existential human situation. Thus interpreted, spirituality is a human universal appearing in many secular as well as religious forms, although its most typical manifestations have been in religious experience. In this essay we discuss research data in support of this theoretical point of view and highlight some of the issues in bringing the two theoretical perspectives together.     

When Meaning Matters: Coping Mediates the Relationship of Religiosity and Illness Appraisal with Well-Being in Older Cancer Patients

When individuals face serious, traumatic illnesses such as cancer, religion can contribute to their coping processes and psychosocial adjustment. In the current study, we examined the relationship between religiosity conceptualized as the religious meaning system, illness appraisal, and psychological well-being with religious and nonreligious coping as potential mediators of this relationship among older cancer patients. In a cross-sectional design, 215 older Polish patients (60–83 years of age; 80% Catholic, 9% Protestant) with gastrointestinal cancer completed measures of religiosity, illness appraisal, religious coping, nonreligious coping, and psychological well-being. Using structural equation modeling analysis, we found support for our model depicting a mediated relationship between religiosity, illness appraisal, and psychological well-being. Three forms of coping—negative religious, problem focused, and meaning focused—were key mechanisms in the relationship between the religious meaning system, positive and negative illness appraisal, and psychological well-being. These findings suggest that both religious factors (religiosity and religious coping) and nonreligious factors (illness appraisal and nonreligious coping) can operate together in influencing older cancer patients’ well-being.     

Social Simulation Models at the Ethical Crossroads

Computational models of group opinion dynamics are one of the most active fields of sociophysics. In recent years, advances in model complexity and, in particular, the possibility to connect these models with detailed data describing individual behaviors, preferences and activities, have opened the way for the simulations to describe quantitatively selected, real world social systems. The simulations could be then used to study ‘what-if’ scenarios for opinion change campaigns, political, ideological or commercial. The possibility of the practical application of the attitude change models necessitates that the research community working in the field should consider more seriously the moral aspects of their efforts, in particular the potential for their use for unintended goals. The paper discusses these issues, and offers a suggestion for a new research direction: using the attitude models to increase the awareness and detection of social manipulation cases. Such research would offer a scientific challenge and meet the ethical criteria.

     

Rethinking Advaita Within the Colonial Predicament: the ‘Confrontative’ Philosophy of K. C. Bhattacharyya (1875–1949)

I shall examine in this paper the distinctive way in which the prominent Indian philosopher Krishnachandra Bhattacharyya (1875–1949) engaged with Advaita Vedānta during the terminal phase of the colonial period. I propose to do this by looking, first, at ways in which Krishnachandra understood the role of his own philosophizing within the colonial predicament. I will call this his agenda in ‘confrontative’ philosophy. I shall proceed, then, by sketching out the unique manner in which this agenda was successfully enacted through his engagement with the Advaitic notion of self-knowledge. Finally, I will suggest that putting K. C. Bhattacharyya’s thought into the historical perspective of cross-cultural philosophy will reveal a number of shortcomings that need to be revised in a postcolonial setup.     

Group Process and Therapeutic Protocol of Intensive Transdiagnostic Group Cognitive-Behavioral Therapy for Anxiety and Personality Disorders in a Day Clinic

This brief report presents group processes and the treatment protocol of intensive, transdiagnostic group cognitive-behavior therapy for anxiety with comorbid personality disorders in a day clinic. It describes the history of and rationale for the development of this 3-month, 15-hour a week group treatment and the utilization of group processes during this therapy. The authors argue that the group format presented here allows the treatment of personality disorders that are frequently comorbid with anxiety disorders.     

A First Order Theory of Functional Parthood

This paper contains a formal theory of functional parthood. Since the relation of functional parthood is defined here by means of the notion of design, the theory of functional parthood turns out to be a theory of design. The formal theory of design I defend here is a result of introducing a number of constraints that are to express the rational aspects of designing practice. The ontological background for the theory is provided by a conception of states of affairs. The theory is accompanied with a formal model. I prove that the theory is sound and complete with respect to this model.     

Psychosocial Conditions of Quality of Life Among Undergraduate Students: A Cross Sectional Survey

Quality of life (QOL) in the context of education is an understudied topic and research related to its’ relation to the sense of coherence (SOC), level of optimism (LOO) and self-efficacy (SE) among students seems to be missing. The rationale for this survey was to fill this gap in knowledge and therefore, the aim of the study is to examine the relationship between students’ QOL and psychological variables such as SOC, LOO and SE, and social ones such as type of faculty, students’ social background and sex. The quantitative cross sectional survey has been conducted at three higher education institutions in Poland in January 2006. The random sample of 396 undergraduate students (average age was 20.5 years) representing 5 different faculties namely physiotherapy, physical education, tourism and recreation, English and Polish philology has been selected and participated in the study. Four reliable and validated research tools have been used to collect the data. These included the SF-36, SOC-29, Seligman’s scale, and GSES. The results have shown to indicate that different variables had a significant effect on particular subscales of the QOL outcomes. For example, among social variables faculty had a significant effect on physical functioning, role limitation due to physical functioning, and changes in health. Sex had a significant effect on role limitation due to emotional problems, social functioning, and energy vitality. Social background had a significant effect on general health. Among psychological variables the sense of coherence was significantly related to all subscales of QOL. A significant effect was noted by self-efficacy on physical and social functioning. Level of optimism had a significant effect on energy-vitality and general health. This research survey has suggested that changes in academic curriculum might be implemented to improve students QOL.     

Market mindset impacts moral decisions: The exposure to market relationships makes moral choices more utilitarian by means of proportional thinking

We show that exposure to market relationships increases people’s tendency to make utilitarian moral choices by means of proportional thinking—the definitional feature of the market mindset. In Experiment 1, participants primed with market relationships made more utilitarian choices in both the trolley and the footbridge dilemmas. In Experiment 2, priming market mindset led to more utilitarian moral choices and to greater focus on the proportion of survivors to victims. Experiment 3 showed that the effect of market mindset on utilitarian choices held only when the numbers of potential deaths and saved lives were clearly specified. A preregistered Experiment 4 demonstrated that the motivation to use proportional thinking mediates the relationship between market mindset and making utilitarian choices. Experiment 5, also preregistered, showed that the main effect we demonstrated is not due to suppressed emotions and that proportional thinking increases utilitarian choices as part of a broader orientation on rationality.
