Predictors of Heart-Focused Anxiety in Patients Undergoing Genetic Investigation and Counseling of Long QT Syndrome or Hypertrophic Cardiomyopathy: A One Year Follow-up

Since Long QT syndrome and Hypertrophic cardiomyopathy are inherited cardiac disorders that may cause syncope, palpitations, serious arrhythmias, and sudden cardiac death, at-risk individuals may experience heart-focused anxiety. In a prospective multi-site study, 126 Norwegian patients attending genetic counseling were followed 1 year with multiple administration of questionnaires, including the Cardiac Anxiety Questionnaire, measuring three distinct symptoms of heart-focused anxiety- avoidance, attention, and fear—in mixed linear analyses. Overall, at 1-year follow-up, patients with clinical diagnosis as compared to patients at genetic risk had significantly higher scores of avoidance (p < .002), attention (p < .005), and fear (p < .007). Sudden cardiac death in close relatives, uncertainty whether other relatives previously had undergone genetic testing, patients’ perceived general health, self-efficacy expectations and procedural satisfaction with genetic counseling were influential in predicting the different symptoms of heart-focused anxiety over time.

Competitive disadvantage makes attitudes towards rape less negative

Evolutionary theorists have argued that perceived competitive disadvantage may lead to more positive evaluation of, and greater likelihood of engaging in, risky and antisocial behavior. However, experimental studies have not yet examined the effects of competitive disadvantage on perceptions of rape. In the current study, we created a manipulation of perceived competitive status to test its effects on beliefs about rape. In one condition, participants were made to feel disadvantaged relative to male peers in terms of financial, physical, and intellectual power, whereas in the other condition they were made to feel advantaged. Participants were 120 heterosexual male undergraduate students. The manipulation was effective; compared to participants in the advantage condition, those in the disadvantage condition rated themselves as significantly worse off financially, shorter, in worse physical shape, and as having lower course marks than the average male student at the university. Compared to perceived competitive advantage, perceived disadvantage led to less negative attitudes towards rape. However, perceived competitive status did not significantly affect justifications and excuses for rape. Future studies using similar experimental manipulations can complement correlational studies and may contribute to greater clarity, precision, and sophistication of research and theory on the role of competitive disadvantage in rape.     

Gender differences in advanced mathematical problem solving

Strategy flexibility in mathematical problem solving was investigated. In Studies 1 and 2, high school juniors and seniors solved Scholastic Assessment Test-Mathematics (SAT-M) problems classified as conventional or unconventional. Algorithmic solution strategies were students' default choice for both types of problems across conditions that manipulated item format and solution time. Use of intuitive strategies on unconventional problems was evident only for high-ability students. Male students were more likely than female students to successfully match strategies to problem characteristics. In Study 3, a revised taxonomy of problems based on cognitive solution demands was predictive of gender differences on Graduate Record Examination-Quantitative (GRE-Q) items. Men outperformed women overall, but the difference was greater on items requiring spatial skills, shortcuts, or multiple solution paths than on problems requiring verbal skills or mastery of classroom-based content. Results suggest that strategy flexibility is a source of gender differences in mathematical ability assessed by SAT-M and GRE-Q problem solving.     

Living with Long QT Syndrome: A Qualitative Study of Coping with Increased Risk of Sudden Cardiac Death

Long QT syndrome (LQTS) is a congenital disorder associated with increased risk of sudden cardiac death; LQTS patients and their families are offered diagnostic or predictive genetic testing. The purpose of this qualitative study was to investigate the psychosocial aspects of living with LQTS, to identify LQTS patients’ daily life challenges and coping strategies, and to describe their experiences with healthcare services. In-depth interviews were conducted with seven individuals who had been tested for long QT genetic mutation. Four of these participants had an implantable cardiac defibrillator (ICD). The participants reported that early and gradually acquired knowledge of the syndrome was an advantage. They also reported experiencing worries and limitations in daily life, but their main concern was for their children or grandchildren. Healthcare providers’ minimal knowledge of LQTS resulted in uncertainty, misinformation, and even wrong advice regarding treatment. The results suggest that regional centers, with the appropriate expertise, should investigate and counsel LQTS patients and their families.     

Parenting Scale: Which Version Should We Use?

Factor analytic studies of one of the widely used measurements of parental discipline, the Parenting Scale (PS), have yielded ambiguous results. The purpose of this study was to compare various forms of the PS in terms of factor structure and other psychometric properties. The sample consisted of 617 mothers and 430 fathers of 2 to 5-year-olds. Confirmatory factor analysis indicated that shorter structural models provided a better fit compared to the original model; however, none led to an optimal fit. Other psychometric properties such as internal consistency, test-retest reliability, concurrent and predictive validity were slightly higher for the original Laxness and Overreactivity subscales. The findings from this study and previous studies suggest that the inter-item relationship in the scale might be too sensitive to sample characteristics, implying that factor analysis might not be the best way to measure the scale’s validity. Nevertheless, other psychometric properties support the use of the Parenting Scale in the assessment of dysfunctional parenting practices. We recommend using the original Laxness and Overreactivity subscales rather than the later models, especially for research purposes.

Auto-affection and the Curvature of Spacetime: Derrida Reading Heidegger Reading Kant

ABSTRACT

This paper has a twofold objective. First, it engages with the interrelation of time, space, and matter in Kant, Heidegger, and Derrida and questions whether and how this interrelation effects the possibility of self-relation. In Kant and the Problem of Metaphysics Heidegger suggests that the very structure of subjectivity is constituted by what he calls the ‘pure self-affection’ of time and thus the possibility of self-relation is intimately bound up with the temporalizing of time. In his 1964–65 seminar, Heidegger: the Question of Being and History, Derrida translates this pure affection of time into the more generic term ‘auto-affection,’ which will remain a pivotal reference point for his deconstruction of the metaphysical privileging of time as presence. Derrida shows how the (im)possibility of auto-affection is bound up not only with time but also with space, or rather with the ‘spacing of time’ that he also refers to as ‘the trace.’ Second, the paper moves across the frontiers of philosophy and physics posing anew the question concerning the interrelations of temporality, spatiality, and materiality. With reference to what in general relativity is called ‘the curvature of spacetime,’ the efficacy of materiality in the movement of auto-affection is called into question.
