How to produce personality neuroscience research with high statistical power and low additional cost

Personality neuroscience involves examining relations between cognitive or behavioral variability and neural variables like brain structure and function. Such studies have uncovered a number of fascinating associations but require large samples, which are expensive to collect. Here, we propose a system that capitalizes on neuroimaging data commonly collected for separate purposes and combines it with new behavioral data to test novel hypotheses. Specifically, we suggest that groups of researchers compile a database of structural (i.e., anatomical) and resting-state functional scans produced for other task-based investigations and pair these data with contact information for the participants who contributed the data. This contact information can then be used to collect additional cognitive, behavioral, or individual-difference data that are then reassociated with the neuroimaging data for analysis. This would allow for novel hypotheses regarding brain–behavior relations to be tested on the basis of large sample sizes (with adequate statistical power) for low additional cost. This idea can be implemented at small scales at single institutions, among a group of collaborating researchers, or perhaps even within a single lab. It can also be implemented at a large scale across institutions, although doing so would entail a number of additional complications.     

The Christian College Advantage? The Impact of Christian Versus Secular Training Among Faculty at Christian Colleges and Universities

Are faculty trained at Christian institutions better equipped to integrate their faith with their professional work? This study uses a mixed methods analysis of Council of Christian Colleges and Universities (CCCU) faculty survey data to analyze whether and in what ways faculty who graduate from Christian undergraduate, master's, and doctoral programs are more apt to identify connections between their faith tradition and their course objectives. Findings show that faculty members prepared at Christian institutions are more likely to see this relationship and may conceive of it in more sophisticated ways. However, the gap is modest.     

The association of relational and physical victimization with hostile attribution bias,emotional distress,and depressive symptoms: A cross‐cultural study

The purpose of the present study was to examine the association between relational victimization and socio‐cognitive patterns (i.e. hostile attribution biases and emotional distress) or social–psychological adjustment problems (i.e. depressive symptoms) in Japanese and European American children (N = 272; ages 9–10). Results showed that relational victimization, which was conceptually different from physical victimization, was associated with a greater level of emotional distress for an overall sample; however, the links between relational victimization and hostile attribution biases and depressive symptoms were evidenced only for Japanese children. A follow‐up analysis revealed that hostile attribution biases had a direct effect on depressive symptoms for European American children; however, these biases mediated the link between relational victimization and depressive symptoms for Japanese children. These findings are discussed from normative and cross‐cultural perspectives.     

Movement in the ipsilesional hand is segmented following unilateral brain damage

Unilateral stroke results in hemiplegia or hemiparesis of the contralateral side of the body. The ipsilateral side of the body, the so-called "good" side, is often assumed to have no deficit. However, there is increasing evidence that the function of the unaffected limbs, especially the upper extremities, is different from that of normal age-matched controls. In the present study, we examined the motor control of both hands of chronic stroke subjects, 6 with left hemisphere brain damage (LHBD) and 5 with right hemisphere brain damage (RHBD). The control group consisted of 5 normal age-matched subjects. The task of the subject was to move a handle by flexing his/her fingers until the target position was reached. The target position was set as 33% of the range of each subject. No time constraints were imposed. The movements of the normal subjects were basically smooth, with few hesitations. In contrast to this, the movements of both hands in the two stroke groups were segmented and characterized by multiple starts and stops. As compared to normals, the time to reach the target, the number of pauses during the movement, and the percent of time spent in pauses, were significantly greater for both hands of the LHBD group. In the RHBD group, the percent of time spent in pauses was significantly greater than the control group for the ipsilesional hand. The increased segmentation seen in the movements of the ipsilesional, as well as the contralesional. hands of the hemiplegic subjects suggests that the motor deficits in stroke patients may be due to a global inability to correctly plan and carry out movements.     

Agency and Virtue: Dimensions Underlying Subgroups of Women

Previous research indicates that the stereotype of women can be considered to have 3 subgroups: housewife, career woman, and sex object. In 2 samples (N = 19 and 35), we found evidence that these subgroups can be reliably distinguished in terms of 2 dimensions: agency and virtue. Participants sorted 27 feminine traits and then rated these traits in terms of their agency and virtue. Cluster analysis and multidimensional scaling with property fitting were used to identify subgroups, to fit virtue and agency dimensions to the subgroups, and to test for differences among the subgroups in terms of virtue and agency. Across both samples, agency and virtue fit the subgroups well (average R ² = .75), produced many significant differences among the subgroups, and are consistent with a system-justification perspective of sexism (Glick & Fiske, 2001) in which a belief in women's virtue and lack of agency reflects and maintains status differences between men and women.     

Schaffer's Demon

Jonathan Schaffer (2010) has summoned a new sort of demon – which he calls the debasing demon – that apparently threatens all of our purported knowledge. We show that any debasing skeptical argument must attack the justification condition and can do so only if a plausible thesis about justification is false.
