Event-related potentials in adolescents with combined ADHD and CD disorder: a single stimulus paradigm

Some studies of the event-related potentials demonstrated a reduction of the voluntary component P3 (P300 or P3b) in youngsters with the attention deficit/hyperactivity disorder (ADHD) or in conduct disorders (CD), and a reduction of the automatic processing component, mismatch negativity, in patients with both ADHD and CD (ADHD+CD). Recently, a passive auditory P3 potential has been elicited by a single stimulus. We therefore tried this potential study in 20 healthy subjects and 20 teenagers with ADHD+CD to search for further evidence of the altered automatic cerebral processing in the latter. Subjects also answered a self-report Dimensional Assessment of Personality Pathology (DAPP). The patient group scored significantly higher on most DAPP traits that reflect problems of emotion control, showed significantly prolonged P2, N2, and P3, and reduced P3. In all subjects Stimulus Seeking was positively correlated with P3 latencies at Fz, Cz, and Pz, and with P3 amplitude at Cz. This study suggests that youngsters with ADHD+CD had pronounced emotion dysregulation, and prominent deficit in passive attention, as reflected by the automatic processing of auditory stimuli.     

The heritability of attitudes: a study of twins.

The genetic basis of individual differences in attitudes was examined in a survey of 195 pairs of monozygotic twins and 141 pairs of same-sex dizygotic twins. A principal components analysis of the 30 attitude items in the survey identified 9 attitude factors, of which 6 yielded significant heritability coefficients. Nonshared environmental factors accounted for the most variance in the attitude factors. Possible mediators of attitude heritability were also assessed, including personality traits, physical characteristics, and academic achievement. Analyses showed that several of these possible mediators correlated at a genetic level with the heritable attitude factors, suggesting that the heritability of the mediator variables might account for part of the heritable components of some attitudes. There was also some evidence that highly heritable attitudes were psychologically "stronger" than less heritable attitudes.     

Heritability of personality disorders in childhood: a preliminary investigation

The heritability of personality disorder features was investigated in 112 child (ages 4-15 years) twin pairs (70 monozygotic and 42 dizygotic pairs). Parents assessed personality disorder features using the Coolidge Personality and Neuropsychological Inventory for Children (CPNI; Coolidge, 1998) that measures 12 personality disorders according to the criteria in the Diagnostic and Statistical Manual of Mental Disorders (DSM-IV) (American Psychiatric Association, 1994). Structural equation model-fitting methods indicated that the median heritability coefficient for the 12 scales was .75 (ranging from .81 for the Dependent and Schizotypal Personality Disorder scales to .50 for the Paranoid and Passive-Aggressive Personality Disorder scales). These results suggest that childhood personality disorders have a substantial genetic component and that they are similar to heritability estimates of personality disorder traits in adults and counter hypotheses that only temperaments and higher-order personality disorder traits have significant genetic components (Paris, 1997).     

Religious Involvement and Dynamics of Marijuana Use: Initiation,Persistence, and Desistence

Studies that examine the effects of adolescent religiosity on the initiation of, persistence in, and desistence from delinquency are rare. Yet, religion may differentially affect dimensions of delinquency in the early life course. Therefore, using data from the National Longitudinal Study of Adolescent Health (Add Health), we examine the relationship between measures of adolescent religion, as well as changes in religious involvement, and later patterns of marijuana use. We also examine the extent to which religious effects, if any, are mediated by key predictors of delinquency drawn from prominent criminological theories. The results suggest that the primary effect of religion on marijuana use is to prevent its initiation in the first place. Only part of religion's preventative effect on initiation is mediated by social bonds, delinquent peers, or self control. Although religious youth are less likely to ever use marijuana, adolescent religious involvement does not significantly predict desistence from marijuana use.     

The Self Psychological Approach to the Life and Theology of Lee Yong Do

Kohut’s theory of the nuclear self and of the two poles of the grandiose self and the idealizing parental imago show clearly the psychological motivations that molded Lee Yong Do’s life and mysticism. Lee’s grandiose and exhibitionistic personality was created by his disturbed family background and reflected the fragmentation in his nuclear self that he attempted to cure by depending on the archaic symbols of power and grandiosity. However, his religious experiences—in particular, his mystical experiences—functioned as a selfobject providing narcissistic balance and altering the structure of his nuclear self. This was possible because of his redefinition of the concepts of strength and power through religious experiences that made him give up a false sense of self-sufficiency.     

Decomposing the interaction between retention interval and study/test practice: the role of retrievability

Even without feedback, test practice enhances delayed performance compared to study practice, but the size of the effect is variable across studies. We investigated the benefit of testing, separating initially retrievable items from initially nonretrievable items. In two experiments, an initial test determined item retrievability. Retrievable or nonretrievable items were subsequently presented for repeated study or test practice. Collapsing across items, in Experiment 1, we obtained the typical cross-over interaction between retention interval and practice type. For retrievable items, however, the cross-over interaction was quantitatively different, with a small study benefit for an immediate test and a larger testing benefit after a delay. For nonretrievable items, there was a large study benefit for an immediate test, but one week later there was no difference between the study and test practice conditions. In Experiment 2, initially nonretrievable items were given additional study followed by either an immediate test or even more additional study, and one week later performance did not differ between the two conditions. These results indicate that the effect size of study/test practice is due to the relative contribution of retrievable and nonretrievable items.     

History,Current Status,and Future Prospects of Counseling in South Korea

Although the counseling profession was introduced to South Korea in the 1950s by American delegates of education, counseling has been only lately recognized as a specialized field that requires distinctive knowledge and skills. In this article, the authors describe the history and the current status of counseling in South Korea and then discuss challenges and future prospects.     

GSK-3β activity in the hippocampus is required for memory retrieval

Several molecules were recently found to be important for the memory retrieval process in the hippocampus; however, the mechanisms underlying the memory retrieval remain poorly understood. GSK-3β has been implicated in the control of synaptic plasticity and memory formation. Here, we investigated the relationship between hippocampal GSK-3β activity and memory retrieval using behavioral and Western blotting methods. We found that GSK-3β was activated in the hippocampus after a retention session in the passive avoidance task. An intrahippocampal injection of the GSK-3β inhibitor, SB 216763, before the retention session blocked memory retrieval (but not reconsolidation) without affecting locomotor activity. These results suggest that GSK-3β activation would be essential for memory retrieval in the hippocampus.     

To What Extent Does the Reporting Behavior of the Media Regarding a Celebrity Suicide Influence Subsequent Suicides in South Korea?

This study investigated the nature of media coverage of a national entertainer's suicide and its impact on subsequent suicides. After the celebrity suicide, the number of suicide‐related articles reported surged around 80 times in the week after the suicide compared with the week prior. Many articles (37.1%) violated several critical items on the World Health Organization suicide reporting guidelines, like containing a detailed suicide method. Most gender and age subgroups were at significantly higher risk of suicide during the 4 weeks after the celebrity suicide. Results imply that massive and noncompliant media coverage of a celebrity suicide can cause a large‐scale copycat effect.     

Office Housework,Burnout, and Promotion: Does Gender Matter?

In The New York Times, Grant and Sandberg (2015) made the case that women perform more office housework and experience more burnout, yet receive fewer career benefits, from performing office housework than do men. However, this claim has not been formally tested. Based on gender role theory, conservation of resources theory, and shifting standards, we test the relationships between gender, office housework, burnout, and promotion. Results revealed that women performed more office housework overall than did men. More specifically, women engaged in more social maintenance OHW, while men engaged in more object maintenance OHW. Contrary to the popular press claim, results showed no significant relationship between office housework and burnout. Moreover, office housework did not mediate the relationship between gender and burnout. In addition, gender moderated the relationship between office housework and promotion such that the relationship was statistically significant for men, but not statistically significant for women. This study contributes to the literature by introducing office housework as a specific form of organizational citizenship behavior and empirically investigating the popular press claim related to office housework.
