Augustine's Ethics of Belief and AvoidingViolence in Religious Disputes

This article is a study of how Augustine's ethics of belief shaped his arguments against unbelief and its legacy in using coercion to settle disputes. After considering the arguments for belief presented by Augustine, the article studies how these were shaped by his understanding of the problem of evil and how the Fall influenced free will. What is noted to be of benefit in Augustine is that he offers arguments in favor of belief, and is convinced that he has shown unbelief to be based on unsound reasoning. By way of contrast, a number of theologians (such as Tertullian, John Calvin, and those under the heading of Reformed Epistemology) are considered who do not believe that arguments are necessary to support belief or reject unbelief. These are contrasted with Augustine and it is argued that they have significant shortcomings in this respect. However, the article concludes that Augustine could have gone farther in supporting the claim that it is clear that God exists, and his own shortcomings have been used to justify coercion in religious belief. If common ground is to be achieved this problem must be corrected and an adequate foundation for clarity must be established.     

Community Psychology, Political Efficacy, and Trust

Much attention has been paid to the effects of political efficacy and trust on political participation. Most studies tend to use efficacy or trust as an independent variable to explain political actions such as voting, campaign involvement, and the like. Despite their importance in explanations of political behavior, relatively little is known regarding mechanisms through which social involvement may influence trust and efficacy. If efficacy and trust are of value, then it is important that we determine how their development can be fostered, and especially whether their development can be promoted through social interaction—such as a sense of community. Borrowing from the field of community psychology, I employ the Sense of Community Index to provide a more nuanced measure of community based on individual perceptions of their community that previous studies were unable to capture. Analyzing original survey data, this paper examines to what extent, if any, a sense of community matters for trust and efficacy. The results demonstrate that social forces, such as community, exert positive and significant effects on internal and external efficacy and personal and political trust, independently of individual traits such as income, age, gender, and education.     

Split-half and parallel reliabilities of the Purdue Pharmacist Directive Guidance Scale

Using R and SPSS, various forms of split-half and parallel reliabilities were calculated. Robust split-half and parallel reliability coefficients for the Purdue Pharmacist Directive Guidance Scale are presented with coefficients greater than .84.     

Distinct neural correlates for two types of inhibition in bilinguals: response inhibition versus interference suppression

To examine the effects of bilingualism on cognitive control, we studied monolingual and bilingual young adults performing a flanker task with functional MRI. The trial types of primary interest for this report were incongruent and no-go trials, representing interference suppression and response inhibition, respectively. Response times were similar between groups. Brain data were analyzed using partial least squares (PLS) to identify brain regions where activity covaried across conditions. Monolinguals and bilinguals activated different sets of brain regions for congruent and incongruent trials, but showed activation in the same regions for no-go trials. During the incongruent trials, monolinguals activated the left temporal pole and left superior parietal regions. In contrast, an extensive network including bilateral frontal, temporal and subcortical regions was active in bilinguals during the incongruent trials and in both groups for the no-go trials. Correlations between brain activity and reaction time difference relative to neutral trials revealed that monolinguals and bilinguals showed increased activation in different brain regions to achieve less interference from incongruent flankers. Results indicate that bilingualism selectively affects neural correlates for suppressing interference, but not response inhibition. Moreover, the neural correlates associated with more efficient suppression of interference were different in bilinguals than in monolinguals, suggesting a bilingual-specific network for cognitive control.     

Exploring interhemispheric collaboration in older compared to younger adults

Physical and Name Identity letter-matching tasks were used to explore differences in interhemispheric collaboration in younger and older adults. To determine whether other factors might also be related to across/within-hemisphere processing or visual field asymmetries, neuropsychological tests measuring frontal/executive functioning were administered, and comparisons were made for participants split into low and high efficiency groups based on performance on the letter-matching tasks. A Task by Across/Within interaction was found for both groups, but with a stronger within-hemisphere advantage for the Physical Task and a weaker across-hemisphere advantage for the Name Task for older participants. More efficient groups and better performers on several neuropsychological tasks showed a reduced across-hemisphere advantage for the Name Identity task. Findings suggest that computational complexity, specific task demands, and perhaps trade-offs between age-related changes in gray and white matter all contribute to whether processing loads are distributed across or within hemispheres as we age.     

In search of the silver lining: the justice motive fosters perceptions of benefits in the later lives of tragedy victims

Past research has demonstrated that people's need to perceive the world as fair and just leads them to blame and derogate victims of tragedy. The research reported here shows that a positive reaction--bestowing additional meaning on the lives of individuals who have suffered--can also serve people's need to believe that the world is just. In two studies, participants whose justice motive was temporarily heightened or who strongly endorsed the belief that reward and punishment are fairly distributed in the world perceived more meaning and enjoyment in the life of someone who had experienced a tragedy than in the life of someone who had not experienced tragedy, but this pattern was not found for participants whose justice motive was not heightened or who did not strongly endorse a justice belief. These results suggest that being motivated to see the world as just--a motivation traditionally associated with victim derogation--also leads people to perceive a "silver lining" to tragic events.
