Self‐Harm in Young Offenders

The prevalence and correlates of self‐harm and suicidal behavior in 515 young offenders (mean age 17.3 years, SD = 1.7) serving community‐based orders (CBOs; n = 242) or custodial sentences (n = 273) in Victoria, Australia, are described. Results from structured interviews showed that 83 (16.1%) participants reported self‐harming in the previous 6 months, and this was more common among those serving custodial sentences than those serving CBOs (19.4% vs. 12.4%; OR 3.10, 95% CI: 1.74–5.55). Multiple incidents were more common in females and 24% (95% CI: 19–39) of participants who had self‐harmed reported having done so with suicidal intent. Self‐harm was associated with recent bullying victimization, expulsion from school, past year violent victimization, cannabis dependence, and risk‐taking behavior in the preceding year. The epidemiological profile of self‐harm in this population appears to be distinct from that seen in the general population. Young offenders who self‐harm are a vulnerable group with high rates of psychiatric morbidity, substance misuse problems, and social risk factors. They may benefit from targeted psychological interventions designed specifically to address impulsivity, delivered both within–and during the transition from–the youth justice system.     

Patient personality and mortality: a 4-year prospective examination of chronic renal insufficiency.

The present study examined the role of personality as a predictor of mortality among patients with chronic renal insufficiency. A prospective evaluation of the influence of personality on patient survival was conducted over an average 49-month period. Cox regression was used to evaluate the effects of 5 dimensions of personality in a sample of 174 patients (100 male and 74 female). At follow-up, 49 patients had died. Significant demographic and clinical predictors of survival included age, diabetic status, and hemoglobin level. After these predictors were controlled for, 2 personality traits, conscientiousness and neuroticism, predicted patient mortality. Patients with high neuroticism scores had a 37.5% higher estimated mortality rate. Patients with low conscientiousness scores had a 36.4% increased mortality rate.     

Sex differences in the original thinking of preschool and elementary school children

Abstract:

The purpose of this study was to assess the development of sex differences in the creative potential of preschool and early elementary school children. Preschool, first‐, and third‐grade children (N = 188) received the Multidimensional Stimulus Fluency Measure (MSFM). The MSFM assesses creative potential in terms of popular and original responses (ideational fluency). Comparisons of the three groups of children indicated that sex differences emerged throughout early elementary school. No sex differences were found within the preschool sample; but by third‐grade, boys were found to score significantly higher than girls on both popular and original responses. These findings were discussed with regard to evaluation, conformity, assimilative strategies, and the environmental factors which might affect creative potential.     

Innovation 101: Promoting Undergraduate Innovation Through a Two-Day Boot Camp

Commitment involves how a person invests resources in a work role over long periods of time. Creativity is a novel, appropriate variation that is embraced by a field of gatekeepers and transforms the symbolic domain. This qualitative analysis (Cohen's kappas of .62, .86, .68 across three coders) addresses the different roles that commitment plays in the careers of 36 writers, depending on what level of creative influence the literary field has attributed to the writer's work. The sample was segmented into genre conformers who played by established literary rules (M = 0.15, SD = 0.18), experimentalists whose innovations have not yet caught on widely (M = 0.80, SD = 0.17), and domain transformers who changed the canon (M = 1.32, SD = 0.27). For genre conformers, commitment compensates. They invest technique in the craft of writing to improve their social standing among other writers, editors, and critics within the field. For experimentalists, commitment defies. They translate their selves into words by twisting traditions and supports to yield new meanings, which gains them an emotional rush plus increased control over their self-expression. For domain transformers, commitment impassions. They trust some beloved aspect of literature, such as a character or poetic form, to convert new minds to the latent possibilities of the domain.     

The relationship between depressive symptoms and error monitoring during response switching

Heightened sensitivity to failure and negative information is thought to be an important maintenance mechanism for symptoms of depression. However, the specific neural and behavioral correlates of the abnormal reactions to errors associated with depression are not yet well understood. The present study was designed to shed new light on this issue by examining how depressive symptoms relate to error monitoring in the context of different task demands. We used a modified flanker task in which the stimulus–response (S–R) mappings were reversed between blocks, differentiating relatively easy nonreversal blocks from the more-demanding S–R reversal blocks. Undergraduates performed this task and then completed a self-report measure of anhedonic depression. The results revealed that depressive symptoms were related to poorer posterror accuracy in the more-difficult S–R reversal blocks, but not in the easier nonreversal blocks. Event-related brain potentials (ERPs) within a subsample of these participants further indicated that depressive symptoms were associated with reduced error positivity (Pe) amplitudes in both block types, suggesting that depressive symptoms were related to reduced attention allocation to errors across the easy and hard blocks. Finally, brain–behavior correlations indicated that highly depressed individuals failed to display a relationship between Pe amplitude and posterror accuracy in the S–R reversal blocks, a relationship that was intact in the low-depression group. Together, these results suggest that task demands play a critical role in the emergence of error-monitoring abnormalities in depression.     

The Effect of Education on Age-Related Functional Activation During Working Memory

Education has been suggested to play a protective role against the development of age-related dementias. Accordingly, we examined modulation of functional activation during working memory by age and education. Eight older individuals with a college education, six older individuals with a high school education, and eight younger individuals with a college education performed a working memory task during O¹⁵ [water] PET scanning. In a voxel-by-voxel whole brain search, older participants with less education demonstrated greater left frontal activation relative to older participants with more education. Older participants with more education demonstrated greater right precuneus activation relative to older participants with less education. This suggests that older less educated participants may have used additional frontal resources to compensate for dysfunctional parietal cortex. These results occurred in the context of similar activation in well-educated younger and older participants. Younger participants had one unique area of activation in the left posterior parietal cortex and no differences in frontal activation were observed between these two groups. The results of this study indicate the need to consider education in age-related neuroimaging studies.
