Effects of Childhood Sexual Abuse on Brain Function as Measured by Quantitative EEG, Neuropsychological, and Psychological Tests (open access)

Effects of Childhood Sexual Abuse on Brain Function as Measured by Quantitative EEG, Neuropsychological, and Psychological Tests

Childhood sexual abuse (CSA) has been the subject of much recent controversy as a result of Rind, Tromovitch and Bauserman's (1998) meta-analytic examination of CSA, which found a weak relationship between CSA and self-reported psychopathology in college samples. There have been few studies of CSA which look beyond self-report. The present study is an exploration of the relationships between CSA, quantitative electroencephalographic (QEEG), neuropsychological, and psychological measurements in 24 high-functioning, unmedicated CSA adults who were matched for age, gender, and handedness with a group of adults without CSA (NCSA). The objectives of this study were to: 1) examine EEG abnormalities associated with CSA, 2) investigate QEEG cortical coherence in the groups using neuroelectric Eigen image (NEI) connectivity indices (Hudspeth, 1999), 3) integrate personality differences associated with CSA with EEG differences, and 4) better understand left versus right hemisphere functioning in CSA using intelligence testing. An examination of QEEG cortical coherence revealed moderate to large effect sizes indicating patterns of decreased connectivity between brain regions on the right frontally in the delta band, and frontally and centro-temporally on the right in the alpha band, and posteriorly in the alpha and beta bands, as well as in the cross-correlation; increased connectivity between …

Emotional Intelligence at Mid Life: A Cross Sectional Investigation of Structural Variance, Social Correlates, and Relationship to Established Personality and Ability Taxonomies (open access)

Emotional Intelligence at Mid Life: A Cross Sectional Investigation of Structural Variance, Social Correlates, and Relationship to Established Personality and Ability Taxonomies

Emotional Intelligence (EI) has been relatively unstudied after young adulthood. Yet there are a variety of reasons to expect that EI may be different at mid life than in young adulthood. Normative life experiences may lead to increases in EI, and as the array of different environments and experiences increases with age, one might expect greater individual differences in EI. Similarly, if EI is located somewhere at the intersection of personality and intelligence, as some have speculated, it may follow a course of structural differentiation similar to cognitive abilities. EI may be more closely linked to social variables such as loneliness and friendships at mid life, and its relation to established personality and ability factors such as the Big Five (Neuroticism, Extraversion, Openness, Agreeableness, and Conscientiousness) and fluid and crystallized abilities may also vary with age. These hypotheses were investigated in samples of 292 young adults and 246 mid life adults, using the Schutte Self Report Emotional Intelligence Inventory, the NEO-Five Factor Personality Inventory, markers of crystallized and fluid ability from Horn's Crystallized/Fluid Sampler, and a variety of other measures. Mid life adults scored higher on overall EI scores, but evidenced no greater range of individual differences than did young …

Identity development across the lifespan. (open access)

Identity development across the lifespan.

In an extension of Louden's work, this study investigated identity development across the lifespan by applying Erickson's and Marcia's identity constructs to two developmental models, the selective optimization and compensation model and a holistic wellness model. Data was gathered from traditionally aged college freshmen and adults older than 60 years of age. Uncommitted identity statuses and work and leisure wellness domains were endorsed across both groups, suggesting that identity for these groups is in a state of fluctuation yet entailing participation as a productive member of society. Emerging adult findings imply that identity diffused and moratorium identity styles are more similar in terms of cognitive, behavioral, and emotional functioning than past literature suggests for this age group. Findings also indicate that identity development is not a process completed by older adulthood, but is an ongoing, lifelong process perhaps driven by contextual factors such as health changes, unpredictable life events, social support group changes, and others. Coping method utilization and overall wellness varied between the two age groups. Conceptually, the SOC model can be viewed as embedded within each of the wellness domains such that selection, optimization, and compensation activities may be carried out within each of the various domains and …

Religiosity and spirituality in younger and older adults. (open access)

Religiosity and spirituality in younger and older adults.

The present study examined the use of MacDonald's Expressions of Spirituality instrument with a younger and older adult sample. Specifically, MacDonald's proposed five factor model was assessed for fit with a sample of college age participants as well as a sample of adults over the age of 65. A confirmatory factor analysis was conducted to assess the fit of this model with samples, and this was followed by an exploratory factor analysis, and the results were considered in light of measurement equivalence and the definitions of the constructs of religiosity and spirituality. Further analyses examined levels of religiousness as well as relationships between religiousness/spirituality and potential correlates, such as postformal thinking, life events including changes and losses, emotional and physical well-being, and family upbringing, comparing young and older adult samples. Results of the confirmatory factor analysis revealed a solution with a better fit than MacDonald's model for both younger and older adults. While the number of factors were the same for both samples, item loadings and cross-loadings differed between the younger and older adult samples. Exploratory factor analysis yielded a four factor solution, with religiousness and spirituality items loading onto one factor. With regard to measurement equivalence, findings appear to …
