Suicidal and nonsuicidal adolescents: different factors contribute to self-esteem

Some risk and protective factors differ in their importance to suicidal and nonsuicidal people. In this research we explore the cross-sectional differences between risk factors among suicidal adolescents and nonsuicidal adolescents by focusing on self-esteem. Sixty-five suicidal and 390 nonsuicidal adolescents were compared on Harter's Self-Perceived Profile for Adolescents, self-concept stability, seeking support, loneliness, and depression. Self-concept stability, loneliness, and peer support correlated differently with self-esteem. In multivariate regression analyses, variance in self-esteem was explained by depression and loneliness, and among nonsuicidal adolescents also by self-concept stability, support, and competencies. Loneliness and self-concept stability related differently to self-esteem in suicidal and nonsuicidal adolescents. When the aim is to enhance self-esteem, this difference may delineate suicidal subgroups that need special interventions.     

The saving power of biotechnology: on public perceptions of a field of technology

Biotechnology emerges in the nexus of academic, political and economic interests. With its strong reliance on a human individual capable of changing matter or organisms in accordance with anticipated goals, biotechnology is closely linked with a modern notion of human agency. In this article, it is argued that in contemporary European societies, biotechnology is perceived in three distinct ways, namely as an agent, as pluripotent, and as salvific. Similar to other forms of technologies, it provides a foil for human activity and projection, but it supersedes them in a quasi religious fashion. The great fascination with the biotechnological enterprise might, thus, express a more fundamental longing for narratives providing coherence and meaning.     

Temperament in children with Down syndrome and in prematurely born children

Parents of three groups of children completed the Children's Behavior Questionnaire (CBQ). Participants were children with Down syndrome aged 4-11 years (n = 55), prematurely born children aged 5 years (n = 97), and a group of normally developing kindergarten children 5-7 years of age (n = 91). Mean levels and factor structures on the CBQ were compared between the three groups. The children with Down syndrome had less attentional focusing and expressed less inhibitory control and less sadness than the normally developing children. There were also group differences in temperament structures, especially a clearer emotional factor of "surgency" among the children with Down syndrome. The only significant difference in mean temperament scores between the premature children and the control group was that the former evinced less attentional focussing. The temperament structures in the Norwegian samples were very similar to those reported in earlier studies, conducted in China and the US.     

Structure of conduct problems in adolescence

Scholars disagree about whether adolescent conduct problems (CPs) form a single behavioral syndrome or whether such problems are better conceptualized as different dimensions. The arguments raised by both sides are addressed and tested empirically by analysing data from a large general population sample of Norwegian adolescents (n = 9,342). Confirmatory factor analyses show that a single syndrome of CPs may be subdivided into three highly correlated factors. The first dimension, destructive covert, includes theft and vandalism, whereas the second, nondestructive covert, reflects avoidance of arenas under adult control. The last dimension, overt, includes school opposition and fighting. This three-factor model fits well for both girls and boys, and individuals in their early and late teens. Results from scale analyses are modestly to moderately indicative of a developmental continuum of severity of CPs ranging from nondestructive covert to overt to destructive covert. Taken together the findings imply that both a unidimensional and a multidimensional perspective on CPs are applicable in the general youth population.     

Influences of preclinical dementia and impending death on the magnitude of age-related cognitive deficits

The authors examined the influence of preclinical dementia and impending death on the cross-sectional relationship between age and performance in tasks assessing episodic memory, visuospatial skill, and verbal fluency. Increasing age was associated with a general decrease in cognitive performance. In addition, those who were to be diagnosed with dementia or had died by a 3-year follow-up, were older, and performed at a lower level than the remaining sample across all cognitive tasks at baseline. Nevertheless, removal of the preclinical dementia and impending death groups from the original sample affected the cross-sectional age-cognition relations relatively little. This pattern of findings suggests that the biological aging process exerts negative influences on cognitive functioning beyond those resulting from disease and mortality.     

Levels of processing: a view from functional brain imaging

This paper briefly reviews two central assumptions of the levels-of-processing framework in the light of findings from recent PET and fMRI studies: First, to address the suggestion that memory traces can be seen as records of analyses carried out for the purposes of perception and comprehension, studies on encoding-retrieval overlap in brain activation patterns are considered. Second, to address the suggestion that deeper, more semantic, processing results in more durable traces, studies of how encoding activity relates to processing depth and subsequent memory performance are examined. The results show that some of the sensory regions that are activated during initial perception are subsequently reactivated during retrieval, and activity in frontal and medial-temporal brain regions is related to depth of processing and level of memory performance. Collectively, these results provide support for central components of the levels framework.     

Body Techniques of Vulnerability: The Generational Order and the Body in Child Protection Services

The paper seeks to analyze children’s bodily vulnerability as grounded in generational order. The thesis is put forward, that the generational order is embodied via body techniques of vulnerability, deployed both by adults and children. In presenting results from research on professional responses to child maltreatment and neglect, three sets of age related body techniques of vulnerability are identified, concerning caregivers, professionals and the children itself.     

Don't be afraid of irrelevant words: The emotional Stroop effect is confined to attended words

The emotional Stroop effect denotes slower responses to the colour of negative words (e.g., death) compared to neutral words (e.g., mug). Popular explanations assume a general power of negative words to capture visual attention. However, in the typical task, the irrelevant word stimulus and the relevant colour stimulus are perceptually integrated. We compared interference from negative words, which were part of the relevant visual object, to interference from negative words that were part of an irrelevant object, or occurred in the background, respectively. Results showed that only negative words in the relevant object delayed colour-naming responses, compared to neutral words. Negative words outside the relevant object failed to affect performance. This finding is at odds with the claim that negative words could capture spatial or object-based mechanisms of visual attention. However, the finding is consistent with the idea that negative words interfere with the allocation of dimensional attention to different features of an attended object.     

Dreading the boards: stress response to a competitive audition characterized by social-evaluative threat

The capacity of psychosocial stressors to provoke the hypothalamic–pituitary–adrenal axis has been demonstrated to vary depending upon a number of psychological factors. Laboratory stressors characterized by social-evaluative threat are proposed to be the most efficacious in the elicitation of a cortisol stress response. Salivary cortisol, cardiovascular, and subjective responses of 16 healthy adults facing a naturalistic stressor characterized by social-evaluative threat (competitive performance auditions) were examined. Audition exposure was sufficient to provoke significant cortisol, arterial blood pressure (systolic and diastolic), and subjective stress responses. Cortisol response reactivity (area under the curve with respect to increase [AUCi]) also correlated with participants' subjective rating of social-evaluative threat. The competitive performance audition context is therefore considered a promising context in which to further explore cortisol responsivity to social-evaluative threat.
