Psychometric Models of Small Group Collaborations

The social combination theory of group problem solving is used to extend existing psychometric models to collaborative settings. A model for pairwise group work is proposed, the implications of the model for assessment design are considered, and its estimation is addressed. The results are illustrated with an empirical example in which dyads work together on a twelfth-grade level mathematics assessment. In conclusion, attention is given to avenues of research that seem most fruitful for advancing current initiatives concerning the assessment of collaboration, teamwork, and related constructs.     

Religious Beliefs,Religious Contexts,and Perceived Interactions with Ex-Offenders

Religious institutions can provide a means of support and resources for many people, particularly, individuals who have criminal histories, specifically parolees, sex offenders, and insanity acquittees. When these individuals are released into the community, they often face difficulties in acquiring shelter, work, and social support. Out of their own volition or as a result of faith-based prison programs, they might turn to religious institutions for help reintegrating into the community. However, whether congregation members are more or less accepting of these individuals is unaddressed in the current literature. Two studies assess the relationship between religious beliefs, religious contexts, legal attitudes, and perceived social interactions with parolees, sex offenders, and insanity acquittees. Results suggest that religious beliefs, legal attitudes, and religious contexts play an important role in individuals’ perceived interactions with these individuals. Religious contexts, specifically, might facilitate more positive social interactions with parolees. Implications are discussed.     

Two Kinds of Consequential Implication

The first section of the paper establishes the minimal properties of so-called consequential implication and shows that they are satisfied by at least two different operators of decreasing strength (symbolized by \(\rightarrow \) and \(\Rightarrow \)). Only the former has been analyzed in recent literature, so the paper focuses essentially on the latter. Both operators may be axiomatized in systems which are shown to be translatable into standard systems of normal modal logic. The central result of the paper is that the minimal consequential system for \(\Rightarrow \), CI\(\Rightarrow \), is definitionally equivalent to the deontic system KD and is intertranslatable with the minimal consequential system for \(\rightarrow \), CI. The main drawback ot the weaker operator \(\Rightarrow \) is that it lacks unrestricted contraposition, but the final section of the paper argues that \(\Rightarrow \) has some properties which make it a valuable alternative to \(\rightarrow \), turning out especially plausible as a basis for the definition of operators representing synthetic (i.e. context-dependent) conditionals.     

On Argumentation Logic and Propositional Logic

This paper studies the relationship between Argumentation Logic (AL), a recently defined logic based on the study of argumentation in AI, and classical Propositional Logic (PL). In particular, it shows that AL and PL are logically equivalent in that they have the same entailment relation from any given classically consistent theory. This equivalence follows from a correspondence between the non-acceptability of (arguments for) sentences in AL and Natural Deduction (ND) proofs of the complement of these sentences. The proof of this equivalence uses a restricted form of ND proofs, where hypotheses in the application of the Reductio of Absurdum inference rule are required to be “relevant” to the absurdity derived in the rule. The paper also discusses how the argumentative re-interpretation of PL could help control the application of ex-falso quodlibet in the presence of inconsistencies.     

Convex MV-Algebras: Many-Valued Logics Meet Decision Theory

This paper introduces a logical analysis of convex combinations within the framework of ?ukasiewicz real-valued logic. This provides a natural link between the fields of many-valued logics and decision theory under uncertainty, where the notion of convexity plays a central role. We set out to explore such a link by defining convex operators on MV-algebras, which are the equivalent algebraic semantics of ?ukasiewicz logic. This gives us a formal language to reason about the expected value of bounded random variables. As an illustration of the applicability of our framework we present a logical version of the Anscombe–Aumann representation result.     

Bisimulation for Conditional Modalities

We give a definition of bisimulation for conditional modalities interpreted on selection functions and prove the correspondence between bisimilarity and modal equivalence, generalizing the Hennessy–Milner Theorem to a wide class of conditional operators. We further investigate the operators and semantics to which these results apply. First, we show how to derive a solid notion of bisimulation for conditional belief, behaving as desired both on plausibility models and on evidence models. These novel definitions of bisimulations are exploited in a series of undefinability results. Second, we treat relativized common knowledge, underlining how the same results still hold for a different modality in a different semantics. Third, we show the flexibility of the approach by generalizing it to multi-agent systems, encompassing the case of multi-agent plausibility models.     

Does Rumination Mediate the Association of Private Prayer,Stress, and Their Interaction with Depression among Christians? A Cross-Sectional Study

Mechanisms underlying significant associations between different types of prayer and depression are unknown. Based on the conceptualization of prayer as stress buffering coping style and the Response Style Theory, we proposed that rumination mediates the association of prayer types and stress with depression. This cross-sectional study (N?=?227 Christians, M_age 41.74, SD 14.82, age range 18–82 years, 76% female) used path modeling to test whether rumination mediated the associations between prayer types and prayer types by stress interactions with depression. Rumination fully mediated the associations of the colloquial and ritual prayer by stress interactions with depressive symptoms, while meditative and petitionary prayer was directly associated with depressive symptoms. Further, petitionary prayer and the ritual prayer by stress interaction were associated with more and not with less rumination and depressive symptoms, respectively. Summarized, first empirical evidence supports an integration of prayer, stress, and rumination into one model of depression. However, the exact nature of their interplay depends on the prayer type. If replicated, our findings allow the integration of prayer into cognitive-behavioral treatment of depression in religious and spiritual clients.     

Emotion Regulation and the Specific Associations with Health Anxiety

This study investigated two primary research aims surrounding health anxiety: (a) to examine what differences exist in emotion regulation strategies of health anxious and non-health anxious populations and (b) to investigate what emotion regulation strategies predict health anxiety, before and after controlling for trait cognitive and somatic anxiety. A total of 95 participants of the general population completed a series of online questionnaires. A single factor between groups MANOVA revealed that a health anxious group scored significantly higher in several emotion regulation strategies: distraction, external attribution, emotion expression and acting out; anxiety-related variables: trait cognitive and somatic anxiety; and beliefs about the negative consequences of becoming ill. Hierarchical regressions showed that several emotion regulation strategies were significantly associated with higher levels of health anxiety, before: distraction, external attribution, capitalising, positive reappraisal and emotional expression; and after: external attribution and capitalising, the control of trait anxiety. Overall, the results demonstrated that (a) emotional intelligence and behavioural attempts to understand emotional experiences may be associated with specific health anxiety symptomology, while a lack of effective cognitive strategies and worry may be responsible for the associated trait anxiety dimensions.     

Reactionary Deconversion from Mormonism: Polarization of Ideological and Behavioral Religiosity Among Active and Former Mormons

In contrast to a growing body of literature examining the experiences and trends of those who leave their faith tradition—particularly among Christian denominations—relatively little is known about those who specifically disaffiliate from Mormonism, although some evidence suggests that former Mormons may be especially likely to embrace secularity or irreligion rather than other religious beliefs and practices. Pursuant to empirically investigating this reactionary dynamic, the current study compared the relative religiosity and secularity of an online sample of active Mormons (n?=?194) and former Mormons (n?=?109) using the Abbreviated Religiousness Measure (ARM), an updated questionnaire of multidimensional religiosity. Results supported the ARM’s improved psychometrics and its hypothesized three-factor structure with both subsamples. Additionally, multivariate and univariate results indicated that active and former Mormon participants from our sample, significantly polarized in their self-reported level of religious beliefs, rituals, and influence on daily behaviors, with active Mormon reporting high religiosity and former Mormons reporting low religiosity or high secularity. Although these results comport with reactionary deconversion dynamics found in other high cost religions, limits to generalizability are discussed. Reasons for and implications of this reactionary phenomenon are also posited.     

Indian Spirituality: How Relevant is Pargament’s Framework?

The psychology of religion and spirituality is a topic of increasing interest in India as well as in the West. An internationally influential framework for defining religion and spirituality has been developed by US psychologist Kenneth Pargament, who conceptualizes spirituality and religion as search processes related to sacred realities. Pargament’s framework has been found to resonate across multiple cultures and has guided and informed empirical research in Jewish, Christian, and Muslim populations. The present paper argues that Pargament’s framework can also coherently resonate with Hinduism and other indigenous Indian religious beliefs and practices. We conclude that future studies of religion and spirituality in Indian contexts may benefit by framing their investigations with reference to Pargament’s approach. Such framing need not be uncritical and would help bring Indian psychology of spirituality/religion in closer contact with psychology of spirituality/religion in other parts of the world, benefiting both India and the worldwide psychology of religion and spirituality.
