Self-perceptions of stability and change in personality at midlife: the UNC Alumni Heart Study

The finding of personality stability in adulthood may be counterintuitive to people who perceive a great deal of change in their own personality. The purpose of this study is to determine whether self-reported perceived changes in personality are associated with actual changes based on a 6- to 9-year follow-up of 2,242 middle-aged male and female participants of the UNC Alumni Heart Study (UNCAHS). Respondents completed the Revised NEO Personality Inventory on two occasions and were asked to reflect back over a 6-year period and assess changes in their personality. The majority of respondents (n = 1,177; 52.5%) reported they had "stayed the same," while 863 (38.5%) reported they had "changed a little" and 202 (9%) reported they had "changed a good deal." Coefficients of personality profile agreement computed to evaluate global personality change for the three perceived change groups were essentially equivalent. Further, directional analyses of domain-specific changes in personality showed that perceived changes were weak predictors of residual gain scores. In an absolute sense, perceptions of stability or change were discordant in 8 of 15 (53%) comparisons. Self-perceptions of change are not an adequate substitute for objective assessments.     

Personality at midlife: stability, intrinsic maturation, and response to life events

Although developmental theories and popular accounts suggest that midlife is a time of turmoil and change, longitudinal studies of personality traits have generally found stability of rank order and little or no change in mean levels. Using data from 2,274 men and women in their 40s retested after 6 to 9 years, the present study examined two hypotheses: (a) that retest correlations should be no higher than about .60 and (b) that there should be small decreases in Neuroticism, Extraversion, and Openness, and small increases in Agreeableness and Conscientiousness. The study also explored the effects of recalled life events on subsequent personality scores. Results did not support the first hypothesis; uncorrected retest correlations uniformly exceeded .60. This was true for all personality traits, including facets of Agreeableness and Conscientiousness not previously included in longitudinal studies. The hypothesized decreases in Neuroticism, Extraversion, and Openness were found, but Conscientiousness showed a small decrease instead of the predicted increase. Life events in general showed very little influence on the levels of personality traits, although some effects were seen for changes in job and marital status that warrant further research.     

Neo-Republicanism and the Domination of Immigrants

Res Publica - Neo-republicanism seems well suited to provide insight into current policies for the control and restriction of immigration. In this paper, I discuss three different accounts of...     

Working memory and early numeracy training in preschool children

Many factors influence children’s performance in mathematical achievement, including both domain-specific and domain-general factors. This study aimed to verify and compare the effects of two types of training on early numerical skills. One type of training focused on the enhancement of working memory, a domain-general precursor, while the other focused on the enhancement of early numeracy, a domain-specific precursor. The participants were 48 five-year-old preschool children. Both the working memory and early numeracy training programs were implemented for 5 weeks. The results showed that the early numeracy intervention specifically improved early numeracy abilities in preschool children, whereas working memory intervention improved not only working memory abilities but also early numeracy abilities. These findings stress the importance of performing activities designed to train working memory abilities, in addition to activities aimed to enhance more specific skills, in the early prevention of learning difficulties during preschool years.     

Twice Hurt: How Newspaper Coverage May Reduce Empathy and Engender Blame for Female Victims of Crime

In a content analysis of 148 newspaper articles we examined whether victims of violent crime (excluding sex crimes) are treated differently according to their gender. Articles taken from 4 newspapers showed that accounts of violent crime personalize male victims more than female victims: more personal information was included about male victims, and males were significantly more likely to be referred to by name rather than by a noun (“the victi”) or pronoun. In a second study we investigated whether such treatment could affect both empathy for the victim and victim blame. Participants read an account of a murder that manipulated victim gender, degree of personal information, and the manner in which the victim was described. Empathy for the victim was increased across victim gender by both inclusion of personal information and referring to the victim by name. Victim blame was also reduced by the inclusion of personal information. Implications of how the news media may subtly reduce empathy and engender blame for female victims are discussed.     

First Order Extensions of Classical Systems of Modal Logic; The role of the Barcan schemas

The paper studies first order extensions of classical systems of modal logic (see (Chellas, 1980, part III)). We focus on the role of the Barcan formulas. It is shown that these formulas correspond to fundamental properties of neighborhood frames. The results have interesting applications in epistemic logic. In particular we suggest that the proposed models can be used in order to study monadic operators of probability (Kyburg, 1990) and likelihood (Halpern-Rabin, 1987).     

WISC-III Cognitive Profiles in Children with ADHD: Specific Cognitive Impairments and Diagnostic Utility

This study aimed to investigate the presence of specific cognitive impairments and the diagnostic utility of the WISC-III in children with ADHD. Ninety-eight children with ADHD and 81 children without ADHD matched by age and gender (control group), between the ages of 6 and 12?years, participated in the study. Children with ADHD revealed the most pronounced deficits in the subtests tapping working memory and processing speed. Freedom from Distractibility was the cognitive profile most impaired and that showed the highest diagnostic accuracy to discriminate children with ADHD. The optimal cutoff scores of the most common WISC-III cognitive profiles revealed greater diagnostic accuracy than the traditional approach of full or partial profiles. Taken together, these results suggested that in the context of a comprehensive psychological assessment, the WISC may provide knowledge about the specific cognitive strengths and weaknesses that characterize this disorder and may be useful in the decision-making process relative to ADHD diagnosis.     

Violence and Latin‐American preadolescents: A study of social brain function and cortisol levels

The present study investigated exposure to violence and its association with brain function and hair cortisol concentrations in Latin‐American preadolescents. Self‐reported victimization scores (JVQ‐R2), brain imaging (fMRI) indices for a social cognition task (the ‘eyes test’), and hair cortisol concentrations were investigated, for the first time, in this population. The eyes test is based on two conditions: attributing mental state or sex to pictures of pairs of eyes (Baron‐Cohen, Wheelwright, Hill, Raste, & Plumb, 2001). The results showed an association among higher victimization scores and (a) less activation of posterior temporoparietal right‐hemisphere areas, in the mental state condition only (including right temporal sulcus and fusiform gyrus); (b) higher functional connectivity indices for the Amygdala and Right Fusiform Gyrus (RFFG) pair of brain regions, also in the mental state condition only; (c) higher hair cortisol concentrations. The results suggest more exposure to violence is associated with significant differences in brain function and connectivity. A putative mechanism of less activation in posterior right‐hemisphere regions and of synchronized Amygdala: RFFG time series was identified in the mental state condition only. The results also suggest measurable effects of exposure to violence in hair cortisol concentrations, which contribute to the reliability of self‐reported scores by young adolescents. The findings are discussed in light of the effects of exposure to violence on brain function and on social‐cognitive development in the adolescent brain.

Ethnicity, education, and the temporal stability of personality traits in the East Baltimore Epidemiologic Catchment Area study

We examined the influence of age, gender, Black vs. White ethnicity, and education on five indices of personality stability and change across an average interval of 8 years in the East Baltimore Epidemiologic Catchment Area study. In the full sample (n = 505, aged 30–88), examination of structural, rank-order, ipsative, and mean level stability, as well as indices of reliable change suggested that NEO-PI-R personality traits showed moderate to high levels of stability over time. There were few age and gender effects on temporal stability but rank-order, ipsative, and mean level stability were lower among Blacks and individuals with lower education. Future research should explore additional demographic predictors of temporal plasticity in a diverse range of samples, and employ observer ratings to assess personality.
