Exploring the Relationship between Psychopathy and Helping Behaviors in Naturalistic Settings: Preliminary Findings

This study examined the helping behavior of participants with high (High-P; 15 males, 13 females) and low (Low-P; 14 males, 16 females) psychopathic traits without their awareness. In the first of three tests, we found Low-P participants offered more help to an apparently lost female confederate than High-P participants. In the second test, High-P compared to Low-P males offered more help to an “injured” female experimenter, the reverse was true for females. In the third test, High-P compared to Low-P females offered more help to a female confederate who had apparently dropped papers they were carrying; whereas the reverse was true for males. Our preliminary findings indicate that context, gender and psychopathic traits interact and impact helping behavior.     

Carnapian explications,experimental philosophy,and fruitful concepts

It seems natural to think that Carnapian explication and experimental philosophy can go hand in hand. But what exactly explicators can gain from the data provided by experimental philosophers remains controversial. According to an influential proposal by Shepherd and Justus, explicators should use experimental data in the process of ‘explication preparation’. Against this proposal, Mark Pinder has recently suggested that experimental data can directly assist an explicator’s search for fruitful replacements of the explicandum. In developing his argument, he also proposes a novel aspect of what makes a concept fruitful, namely, that it is taken up by the relevant community. In this paper, I defend explication preparation against Pinder’s objections and argue that his uptake proposal conflates theoretical and practical success conditions of explications. Furthermore, I argue that Pinder’s suggested experimental procedure needs substantial revision. I end by distinguishing two kinds of explication projects, and showing how experimental philosophy can contribute to each of them.     

Nationwide survey of contraceptive and sexually transmitted infection knowledge,attitudes and skills of university students in Portugal

Sexually transmitted infections and (STIs) unintended pregnancies are contemporary public health concerns. Understanding factors (e.g. knowledge, attitudes and skills) influencing sexual behaviours of university students are critical to develop targeted and tailored risk-reduction interventions for this vulnerable population. Thus, the goals of this study were to describe sexual behaviours and analyze differences between genders for sexual behaviours; to identify whether differences exist between genders and age groups regarding knowledge, attitudes and skills concerning contraceptive methods and STIs, and to evaluate the association of knowledge with attitudes and skills with sexual behaviour among university students in Portugal. The sample included 3278 students. Results show that the majority were sexually active and use condoms and oral contraceptives. In general, university students have high knowledge, positive attitudes and skills about contraception and STIs. Gender analyses indicated that women had greater knowledge, and more favourable attitudes, and higher skills toward contraceptive and STI preventive behaviour College students, in particular, face new challenges in sexual health and would benefit from more comprehensive education aimed at promoting healthy decision-making about family planning and STI prevention.     

The relationship between alliance ruptures and hope for change through counseling: A mixed methods study

The negative impact of alliance ruptures on clients’ experiences within the therapeutic process is well documented. One such negative influence may include clients’ hope for counseling as a helpful process. This study used a mixed methods design to explore how alliance ruptures are related to hope for change through counseling. Quantitative data (N = 105) indicated that those who experienced ruptures reported lower levels of the components of hope for change through counseling, (a) pathways and agency, and (b) goal identification. More frequent ruptures and rupture repairs were significantly related to participants’ (n = 35) pathways and agency. Phenomenological analysis of qualitative participants’ (N = 5) experiences elicited 218 meaning units grouped into four themes: disengagement and mistrust in therapy, deepened distress, questioning one’s hope for and belief in therapy, and resilience for therapy. Qualitative and quantitative data indicate that alliance ruptures are related to lower degrees of hope for change through counseling. Results suggest that clients’ perceptions of ruptures fostered disengagement and mistrust of therapists. However, when therapists act to repair ruptures, they may effectively re-engage some degree of hope for change through counseling in clients. Lastly, the role of clients’ persistence in therapy despite experiencing ruptures is discussed.     

A Bayesian hierarchical model for the measurement of working memory capacity

Working memory is the memory system that allows for conscious storage and manipulation of information. The capacity of working memory is extremely limited. Measurements of this limit, and what affects it, are critical to understanding working memory. Cowan (2001) and Pashler (1988) suggested applying multinomial tree models to data from change detection paradigms in order to estimate working memory capacity. Both Pashler and Cowan suggested simple formulas for estimating capacity with these models. However, in many cases, these simple formulas are inadequate, and may lead to inefficient or biased estimation of working memory capacity. I propose a Bayesian hierarchical alternative to the Pashler and Cowan formulas, and show that the hierarchical model outperforms the traditional formulas. The models are easy to use and appropriate for a wide range of experimental designs. An easy-to-use graphical user interface for fitting the hierarchical model to data is available.     

RELIGION,SCIENCE, AND NATURE: SHIFTS IN MEANING ON A CHANGING PLANET

Abstract This article explores how religion and science, as worlding practices, are changed by the processes of globalization and global climate change. In the face of these processes, two primary methods of meaning making are emerging: the logic of globalization and planetary assemblages. The former operates out of the same logic as extant axial age religions, the Enlightenment, and Modernity. It is caught up in the process of universalizing meanings, objective truth, and a single reality. The latter suggests that the processes of globalization and climate change break open any universalizing attempt at meaning onto a proliferation of different, evolving planetary contexts. Both science and religion are affected by these changes, and the ways in which they shape our understandings of and relationship to the rest of the natural world are changed.     

The discounting model selector: Statistical software for delay discounting applications

Original, open‐source computer software was developed and validated against established delay discounting methods in the literature. The software executed approximate Bayesian model selection methods from user‐supplied temporal discounting data and computed the effective delay 50 (ED50) from the best performing model. Software was custom‐designed to enable behavior analysts to conveniently apply recent statistical methods to temporal discounting data with the aid of a graphical user interface (GUI). The results of independent validation of the approximate Bayesian model selection methods indicated that the program provided results identical to that of the original source paper and its methods. Monte Carlo simulation (n = 50,000) confirmed that true model was selected most often in each setting. Simulation code and data for this study were posted to an online repository for use by other researchers. The model selection approach was applied to three existing delay discounting data sets from the literature in addition to the data from the source paper. Comparisons of model selected ED50 were consistent with traditional indices of discounting. Conceptual issues related to the development and use of computer software by behavior analysts and the opportunities afforded by free and open‐sourced software are discussed and a review of possible expansions of this software are provided.
