One of teenagers’ key developmental tasks is to engage in new and meaningful relationships with peers and adults outside the family context. Attachment-derived expectations about the self and others in terms of internal attachment working models have the potential to shape such social reorientation processes critically and thereby influence adolescents’ social-emotional development and social integration. Because the neural underpinnings of this developmental task remain largely unknown, we sought to investigate them by functional magnetic resonance imaging. We asked n = 44 adolescents (ages 12.01–18.84 years) to evaluate positive and negative adjectives regarding either themselves or a close other during an adapted version of the well-established self-other trait-evaluation task. As measures of attachment, we obtained scores reflecting participants’ positive versus negative attachment-derived self- and other-models by means of the Relationship Questionnaire. We controlled for possible confounding factors by also obtaining scores reflecting internalizing/externalizing problems, schizotypy, and borderline symptomatology. Our results revealed that participants with a more negative attachment-derived self-model showed increased brain activity during positive and negative adjective evaluation regarding the self, but decreased brain activity during negative adjective evaluation regarding a close other, in bilateral amygdala/parahippocampus, bilateral anterior temporal pole/anterior superior temporal gyrus, and left dorsolateral prefrontal cortex. These findings suggest that a low positivity of the self-concept characteristic for the attachment anxiety dimension may influence neural information processing, but in opposite directions when it comes to self- versus (close) other-representations. We discuss our results in the framework of attachment theory and regarding their implications especially for adolescent social-emotional development and social integration. 相似文献

Incongruences of Ethical and Legal Norms in Academia: the Case on Revocation of Doctoral Degrees 总被引:1,自引:0,他引:1
In the academic setting as in any organization legal norms prevail and are assumed to be congruent with ethical norms. Nevertheless, there are cases when the ratio of ethical and legal norms is inadequate and disproportional, especially those dealing with socially responsible decisions in academia. For this reason, the aim here is to analyse incongruences of ethical and legal norms related to the revocation of doctoral degrees in Lithuania, illustrated with examples of deviant behaviour by academic degree holders in terms of decisions of the courts and the ombudsman for academic ethics. Lithuania, being a Member State of the European Union, is currently facing the challenge of implementing newly-adopted laws related to the revocation of doctoral degrees. Accordingly, data were collected from available online official sources to gain more comprehensive evidence, and then analysed using the inductive approach of qualitative content analysis. Research findings show that there is still a thin line between ethical and legal norms, and this line fluctuates depending on nuanced considerations. This is to say that it is still problematical to dress ethical principles in legal clothing. 相似文献

This study explores aesthetic preferences towards boa and python species among pre-school children and adults, and compares the ratings between the two groups. A set of snake photographs was presented (56 species) to children and adult respondents. The respondents were asked to select the five most preferred and five least preferred species. The children’s agreement on which species were ‘beautiful’ and which were ‘ugly’ was statistically significant and a positive relationship between the mean ranks provided by children and adults was also found (r = .54, P < .001). Children preferred species with thick necks and inconspicuous heads, usually small species, harmless to children. Large pythons probably posed more danger to children than they did to adults during human evolution in African savannas and therefore we hypothesize that young children’s aesthetic preferences were shaped by natural selection through interactions with dangerous snakes. 相似文献

Psychopathy attracts considerable interdisciplinary interest. The idea of a group of people with abnormal morality and interpersonal relations raises important philosophical, legal and clinical issues. However, before engaging these issues, we ought to examine whether this category is scientifically grounded. We frame the issue in terms of the question whether ‘psychopathy’ designates a natural kind according to the cluster approaches. We argue that currently there is no sufficient evidence for an affirmative answer to this question. Furthermore, we examine three ways of dealing with the category of psychopathy. We could eliminate the category, revise it, or subscribe to a more encompassing account of kinds, which could capture psychopathy as it is currently conceptualised. We argue that while a revision of the category of psychopathy is to be expected with empirical and theoretical advancements, we also emphasise its role in clinical and forensic research, which makes it an important pragmatic kind. 相似文献

In our study, we aimed to analyse the effect of child gender on parental and child interactive play behaviour, as well as to determine relations between parental general knowledge of child development and parental play behaviour in two developmental periods, namely toddlerhood and early childhood. The sample included 99 children (50 toddlers 1–3 years-old; 49 preschoolers 3–5 years-old) and their parents. Parent–child interactive play with a standard set of toys was observed and assessed in the home setting. We found that parental and child play behaviours were closely related in both age groups. In addition, child’s gender affected child, but not parental, play behaviour such that girls more frequently established the content of play, sustained play frame, and used more symbolic transformations during play than boys did. Parents’ general knowledge of child development was associated with both parental education and parental play behaviour. The findings are applicable to different professionals working with children and their parents in the preschool period. 相似文献

The aim of this study was to test the hypothesis that a combined relaxation (applied tension release, ATR) and specific shooting training regimen may enhance shooting ability of biathlon athletes. Seven biathletes of high national level were randomized into an experimental group (age 20 ± 5 years; Vo2max 60 ± 8 mL kg(-1) min(-1)) and were asked to add this special training intervention to their regular training for 10 weeks, while five other biathletes served as controls (age 19 ± 2 years; Vo2max 57 ± 10 mL kg(-1) min(-1)). The shooting ability of the subjects was assessed before and after the intervention at rest and after roller skiing on a treadmill in a laboratory-based competition simulating assessment. After the intervention period, the experimental group demonstrated a significantly enhanced shooting performance compared to the control group. No changes in Vo2max or in heart rate and Vo2 responses were observed before and after the intervention in either group and there were no differences between the groups in these parameters. Thus, the preliminary conclusion is that a combination of ATR and specific shooting training seems to be instrumental in enhancing the shooting performance in biathlon. 相似文献

This study examined the factorial structure and validity of the Hare Psychopathy Checklist: Screening Version (PCL:SV) in
a European forensic context. A random sample of 257 criminal offenders from the Lithuanian prison population were administered
the PCL:SV (Hart et al. 1995). The pattern of validity coefficients in this sample was comparable to other North American and non-North American samples.
Several theoretical factorial structures for the PCL:SV were tested and compared. The two-factor model was not supported,
while three- and four-factor models provided an acceptable fit to Lithuanian data. The four-factor model showed significantly
better fit compared to the two-factor model. Correlations between PCL:SV factors and demographic variables confirm construct
validity. However in the four-factor model, when controlling for correlations of the remaining three factors, only the Antisocial
factor significantly correlated with variables related to criminal activity. It was concluded that the overall results of
the PCL:SV in a male sample of Lithuanian offenders support cross-cultural generalizability of the construct of psychopathy
as measured by the PCL:SV. 相似文献

We examined the role of impulsivity in the development of peptic ulcer disease (PUD). The subjects were initially healthy 4636 hospital employees aged 19–62 who responded to a questionnaire on personality, health habits, mental health, and PUD in 1998 and 2000. We used multivariate logistic analyses to determine the relationship between impulsivity and newly-diagnosed PUD among those employees who did not have PUD at baseline. Impulsivity was assessed with the Karolinska Scale of Personality. High level of impulsivity was associated with increased 2-year incidence of doctor-diagnosed PUD after adjustment of age, gender, education and shift work (odds ratio = 2.42, 95% confidence interval = 1.21–4.82). Additional adjustment for the effects of smoking, alcohol consumption, BMI, physical activity, minor psychiatric morbidity and diagnosed depression and other psychiatric disease had little effect on this relationship. The present study suggests that impulsivity may be a risk factor for the development of PUD. 相似文献

The paper examines the psychometric properties of the leadership practices inventory (LPI) in the framework of item response theory (IRT). The LPI assesses five dimensions (i.e. leadership practices) of transformational leadership and consists of 30 items. IRT is a model‐based theory that relates the characteristics of questionnaire items (item parameters) and characteristics of individuals (latent variables) to the probability of choosing each of the response categories. The theory does not assume that the instrument is equally reliable for all levels of the latent variable examined. Samejima's graded response model was used to estimate LPI item characteristics, such as item difficulty and item discrimination power. The results show that some items are redundant in the sense they contribute little to the overall precision of the instrument. Moreover, the LPI seems to be most precise and reliable for respondents with low to medium leadership competence, whereas it becomes increasingly unreliable for high‐quality leaders. These findings suggest that the LPI is best used for training and development purposes, but not for leader selection purposes. 相似文献
