A Logical Transmission Principle for Conclusive Reasons

Dretske's conclusive reasons account of knowledge is designed to explain how epistemic closure can fail when the evidence for a belief does not transmit to some of that belief's logical consequences. Critics of Dretske dispute the argument against closure while joining Dretske in writing off transmission. This paper shows that, in the most widely accepted system for counterfactual logic (David Lewis's system VC), conclusive reasons are governed by an informative, non-trivial, logical transmission principle. If r is a conclusive reason for believing p in Dretske's sense, and if p logically implies q, and if p and q satisfy one additional condition, it follows that r is a conclusive reason for believing q. After introducing this additional condition, I explain its intuitive import and use the condition to shed new light on Dretske's response to scepticism, as well as on his distinction between the so-called ‘lightweight’ and ‘heavyweight’ implications of a piece of perceptual knowledge.     

Trans‐Congregational Triadic Closure: Churchgoers’ Networks Within and Beyond the Pews

Triadic closure is the common tendency for connections to emerge between people's social network ties. This phenomenon has clear implications for congregational networks and may underlie many of the social benefits associated with church involvement. Less documented in the sociology of religion, however, is the occurrence of triadic closure involving congregational and noncongregational relationships within people's close personal networks. To conceptualize this boundary‐spanning network overlap, we elaborate the concept of trans‐congregational triadic closure (TCTC). Using data from the Portraits of American Life Survey—a project that examines both general and congregation‐specific networks of U.S. adults—we consider how religious tradition, macro‐level context, and individual factors predict the occurrence of TCTC in churchgoers’ networks. Findings suggest pronounced differences between evangelicals and mainline Protestants, a considerably lower likelihood of TCTC in densely populated areas, and higher likelihoods of TCTC corresponding with long durations of congregational involvement. We conclude by noting some of the implications of TCTC for the lives of individual believers and for religious organizations, and suggest ways that this concept could elucidate further aspects of contemporary religious life.     

The network of conscientiousness

According to the network perspective, the coalescence of several personality characteristics into major personality dimensions results from a pattern of complex interactions that can be modeled as a network. We focused on one personality dimension, conscientiousness, and on its main facets. We administered a large battery of questionnaires to two samples (N = 210 and N = 230) and analyzed them by means of network analysis. The results showed that some elements of the network, such as general self-control and orientation toward the future, characterized all facets. These “shared” elements could be responsible for the facets to clump into one major dimension. Other elements of the network uniquely characterized different facets. These “unique” elements could underlie the main differences among conscientiousness facets.     

Cognitive Organization of Favorable and Unfavorable Beliefs About Performing a Behavior

Abstract

Intentions to perform behaviors are influenced by beliefs about their consequences, but researchers have not addressed how such beliefs are cognitively organized. In 3 experiments, the authors tested the hypothesis that beliefs are organized according to whether they are favorable or unfavorable in regard to performing a behavior. In Experiment 1, a group of U.S. students first read a list of beliefs favorable and unfavorable to going to a vacation resort and then listed their beliefs about condom use. In Experiment 2, another group of U.S. students listed their beliefs about condom use. In Experiment 3, a 3rd group of U.S. students listed their beliefs about a novel behavior (asking the experimenter for candy). The results of all 3 experiments were consistent with the hypothesis that people cognitively organize their beliefs according to whether they are favorable or unfavorable to the behavior in question.     

The intergenerational transmission of need for closure underlies the transmission of authoritarianism and anti-immigrant prejudice

Previous research has identified need for closure (NFC) as an important motivational-cognitive basis of authoritarianism and prejudice. However, to date, the role of NFC in the intergenerational similarity in authoritarianism and prejudice has remained unclear. In a sample of 169 parent–child dyads, we investigated the similarity between parents and children in NFC and tested whether this intergenerational similarity may account for the intergenerational similarity in authoritarianism and anti-immigrant prejudice. Our results revealed that parental levels of NFC were indeed concordant with the levels of NFC in their children. Even more importantly, parental NFC was indirectly related to child authoritarianism and prejudice in two ways. The first pathway proceeded through the direct relationships between parental and children’s levels of authoritarianism and prejudice. The second pathway, however, bypassed parental levels of authoritarianism and prejudice and proceeded through the intergenerational similarity in NFC. Our findings thus indicate that a significant portion of children’s levels of authoritarianism and anti-immigrant prejudice can be explained by parent–child similarity in motivated cognition. Implications for developmental theories of prejudice acquisition are discussed.     

Closure of autobiographical memories: The effects of written recounting from first- or third-person visual perspective

Autobiographical memories are recalled with varying degrees of psychological closure. Closure is a subjective assessment of how far a remembered experience feels resolved, and it has been suggested that one predictor of closure is the amount of emotional detail in the memory. Study 1 examined which aspect of emotional detail is important for closure, and showed that open and closed negative memories were distinguished by ratings of emotion evoked during recall, not by remembered emotion from the time of the event. The recall of open memories was accompanied by more intense, more negative, and less positive emotion than the recall of closed memories. Biased retelling of memories has been shown to influence closure and on the basis of evidence that third-person recall serves a distancing function, Study 2 examined whether instructions to repeatedly recount an open memory from a third-person perspective would increase closure compared with a single or repeated recounting from a first-person perspective. While repeated third-person recounting had the greatest influence on closure, there were also increases in the first-person recounting groups. The results suggest that closure can be increased by reporting memories in written narrative form, particularly if repeatedly expressed from the third-person perspective.     

A mechanism model of the effect of hedonic product consumption on well‐being

In response to recent calls for research into activities that may increase happiness, this study uses longitudinal data to investigate changes in within-subject, instead of between-subject, well-being. In the context of hedonic product consumption, this study reveals a mechanism by which consumption influences well-being through the mediating effect of satisfaction with associated life domains. Four years of data from a large national panel survey show that consuming hedonic products has indirect effects on well-being, by improving consumers' satisfaction within relevant life domains. High hedonic consumption improves satisfaction with relevant life domains, primarily through more frequent consumption of low-cost hedonic products rather than less frequent consumption of high-cost hedonic products.     

Motivational sources of confirmation bias in criminal investigations: the need for cognitive closure

In two experiments, criminal investigators (N = 50) and undergraduate students (N = 68) read a set of facts from the preliminary investigation of a homicide case. Participants' initial hypothesis regarding the crime was manipulated by providing background information implying that the prime suspect had a jealousy motive or that there might be an alternative perpetrator. Students displayed a framing effect, such that guilt was ascribed to the prime suspect only when a potential motive was presented, whereas investigators did so regardless of hypothesis, thus being less sensitive to alternative interpretations. Investigators' need for cognitive closure (NFC) moderated the effect of the hypothesis on perceptions of the strength of the evidence against the prime suspect; high (v low) NFC investigators were less likely to acknowledge inconsistencies in the material when presented with a potential motive, but were more likely to do so when made aware of the possibility of an alternative perpetrator. Interpretations are somewhat clouded by the fact that dispositional NFC did not seem to affect in a consistent manner participants' motivation toward the experimental task.

Role of personal endorsement of outgroup members' distinctive values and need for cognitive closure in attitude towards the outgroup

The present study was designed to examine the role of the perceived culture of the outgroup and the perceiver's cognitive style on the intergroup process. We conducted a survey among mainland Chinese college students to discover the role of their personal endorsement of Hong Kong Chinese's distinctive values and need for cognitive closure in predicting their attitude towards the Hong Kong Chinese outgroup. Results showed that mainland Chinese who gave a higher endorsement of Hong Kong Chinese values were more likely to show a positive attitude towards Hong Kong Chinese, especially for people with a higher need for cognitive closure. These results were discussed in terms of the function of shared social reality on the formation of positive intergroup attitude. Future directions for intergroup research were proposed based on these findings.
