Self‐Reported Family Socioeconomic Status,the 5‐HTTLPR Genotype,and Delinquent Behavior in a Community‐Based Adolescent Population

Twin and adoption studies have demonstrated a significant contribution of both genetic and environmental factors to antisocial and delinquent behavior. Associations have been reported between the serotonin transporter (5‐HTT) and aggression, and between socioeconomic status (SES), aggression, and serotonergic functions of the brain. We aimed to investigate associations between the 5‐HTTLPR genotype and family SES in relation to delinquent behavior among adolescents. A total of 1,467 17‐ to 18‐year‐old students in the county of Västmanland, Sweden, anonymously completed a questionnaire and gave a saliva sample. Family SES had a U‐shaped relation to delinquency, where adolescents with low and high family SES were the most delinquent. There were curvilinear interactions between the 5‐HTTLPR genotype and family SES in relation to delinquency. Among individuals having high family SES, boys with the LL (homozygous for the long allele) or LS (heterozygous) genotypes and girls with the SS (homozygous for the short allele) or LS (heterozygous) genotypes showed the highest delinquency scores. Among individuals having low family SES, boys with the LL (homozygous for the long allele) genotype and girls with the LS (heterozygous) genotype showed the highest delinquency scores. The present study suggests evidence for an interaction between family SES and the 5‐HTTLPR genotype in relation to juvenile delinquency. Aggr.

Visual Perception in Acoustically Deprived and Normally Hearing Children

In the present study an attempt was made to establish if and to what extent auditory deprivation modifies the processes of visual analysis and synthesis. The study included 54 children aged 10–16 years with hearing impairment attending the School and Educational Center for Children with Hearing Impairment in Wroc?aw (group I) and 127 children with normal hearing acuity attending public schools (group II), forming a reference group. Hearing impairment in the children of group I was from 60 to 100 dB. In 9 of these children the hearing impairment was inherited, while in some others it was acquired and resulted from rubella during the mother's pregnancy (5 subjects) or a severe disease course in childhood, for instance cerebral meningitis (4 subjects) and otolaryngologic antibiotic therapy (7 subjects). In the remaining subjects the reason for auditory deprivation was unknown. Hearing impairment, apart from genetically conditioned causes, appeared in the first months or years of life. The general intellectual level of the examined children was similar to that of their control counterparts, which was confirmed by school psychologists during a routine examination. The examination was performed by means of two tests from the Nonverbal Score of the Wechsler Intelligence Scale for Children: Puzzles and Block Design. The children with a hearing deficit generally needed more time to perform the tasks than those with normal hearing. The investigated parameters of visual perception improved in correlation with age, but the dynamics of these changes were different in the two study groups.     

Dutch and Polish Perceptions of Leadership and Culture: The GLOBE Project

In this paper the objectives of a new international research project that focuses on the perception of leadership across cultures will be presented. The definition of leadership will be discussed in relation to cross-cultural leadership research. The ideas and theory on which the project is based will be introduced along with several of the hypotheses the project is designed to test. Besides testing the general hypotheses, results obtained in the GLOBE study can also be used for a more focused comparison between two countries. In this paper, differences in preferred leadership attributes and national culture dimensions in The Netherlands and Poland are presented. A total of 287 Dutch managers from six organizations and 277 Polish managers from six organizations filled out questionnaires. The results indicate that Dutch and Polish cultures differ strongly on power distance, uncertainty avoidance and future orientation. Regarding preferred attributes for outstanding leadership, Polish respondents score especially high on administrative skills, vision, and diplomacy, whereas Dutch managers emphasize integrity, inspirational behavior and vision. Polish respondents are also less negative about autocratic leadership.     

Influence of Religiosity on the Quality of Life and on Pain Intensity in Chronic Pancreatitis Patients After Neurolytic Celiac Plexus Block: Case-Controlled Study

The quality of life in patients with chronic pancreatitis (CP) is reduced due to their suffering of high levels of pain. It has been presented that quality of life can also be linked to religiosity and/or spirituality. The aim of this study is to assess the influence of religious practices on the quality of life and on the subjective level of pain in CP patients. Ninety-two patients (37 women and 55 men) with chronic pancreatitis were treated invasively for pain with neurolytic celiac plexus block (NCPB). The religiosity of the patients was recorded and served as a dichotomizer. Group 1 was for patients who claimed to have no contact with the church or to have very sporadic contact (N = 35 patients). Group 2 was for patients who claimed to have deep faith and were regular participants at church activities (N = 57 patients). Visual analogue scale was used to assess pain, while the quality of life was measured by using QLQ C-30 questionnaire adapted for chronic pancreatitis patients in Polish population. The patients were assessed prior to the pain-relieving intervention and subsequently 2 and 8 weeks after it. The intensity of pain was reduced in both groups significantly after performing the NCPB. Patients who declared a deep faith reported higher level of pain on the VAS scale prior to intervention than non-religious patients. Quality of life in both groups of patients significantly improved after NCPB. Following NCPB, global quality of life in patients who declared higher religiosity/church attendance was significantly higher (79.88) than for those patients who have no contact or sporadic contact with the church (44.21, P < 0.05). NCPB resulted in significant reduction of pain and increase in quality of life in both groups of patients with CP. Nevertheless, in the group declaring higher religiosity/church attendance, reported pain was higher, but, despite that, quality of life better. It may be concluded that religious practices might serve as an additional factor improving quality of life and coping in patients suffering from chronic pancreatitis.     

Spiritual But Not Religious? Evidence for Two Independent Dispositions

Some psychologists treat religious/spiritual beliefs as a unitary aspect of individual differences. But a distinction between mysticism and orthodox religion has been recognized by scholars as well as laypersons, and empirical studies of "ism" variables and of "spirituality" measures have yielded factors reflecting this distinction. Using a large sample of American adults, analyses demonstrate that subjective spirituality and tradition-oriented religiousness are empirically highly independent and have distinctly different correlates in the personality domain, suggesting that individuals with different dispositions tend toward different styles of religious/spiritual beliefs. These dimensions have low correlations with the lexical Big Five but high correlations with scales (e.g., Absorption, Traditionalism) on some omnibus personality inventories, indicating their relevance for studies of personality.     

The suppressing effect of chlorpromazine treatment on alimentary-social differentiation in amygdala dogs

Experiments were performed on dogs with bilateral electrolytic damage of dorso-medial amygdala. Before the operation dogs were trained in alimentary-social reward differentiation. It consisted in conditioning of instrumental responses of either right or left foreleg to two different tones respectively. Chlorpromazine was injected intramuscularly in 1,5 mg/kg dose during four consecutive days, beginning at third to fifth week after the operation. Amygdala damage produced significant deterioration of the instrumental performance both reinforced by food and by social-sensory rewards. Chlorpromazine produced further dramatic decrease of performance of both responses. It was concluded that chlorpromazine exerts a suppressing effect on motivated behavior reinforced by positive rewards in amygdala dogs. As the effect of chlorpromazine and medial amygdalar damage are summated it may be suggested that the deficit of medial amygdala neurons impairs similar neurochemical mechanisms, (probably dopaminergic and α-adrenergic transmission) as does chlorpromazine.
