Risk- and protective factors for memory plasticity in aging

ABSTRACT

Risk and protective factors for cognitive function in aging may affect how much individuals benefit from their environment or life experiences by preserving or improving cognitive abilities. We investigated the relations between such factors and outcome from episodic-memory training in 136 healthy young and older adults. Tested risk factors included carrying the ?4 variant of the apolipoprotein E allele (APOE), age, body mass index, blood pressure, and cholesterol. Protective factors included higher levels of education, intelligence quotient (IQ), physical activity, fatty acids, and vitamin D. Average increases in memory performance were seen after training, with ample variation between individuals. Being young, female, and having higher IQ were positive predictors of memory improvement. No other relationships were observed. Similar benefit was observed across APOE allelic variation. This indicates that beyond IQ, age, and sex, known risk -and protective factors of cognitive function in aging were not significantly related to memory plasticity.     

Factor structure of the Friends and Family interview

The aim of this study was to specify the latent construct structure of the Friends and Family Interview (FFI: Steele & Steele, 2005) based on its dimensional scale coding protocol. The FFI is a semi-structured interview measuring attachment in middle childhood. We analyzed data from 341 FFI interviews with children aged 7–12 years, recruited in the Scandinavian Öresund Region. Exploratory Factor Analysis revealed a three-component model as best fitting the data. The first component, denoting attachment security, gathered all dimensional scales for evidence of secure base/safe haven regarding mother/father and coherence in the child’s narrative style, along with scales regarding reflective functioning, self-perception, and social functioning. The second component comprised preoccupying feelings of anger, but also derogation. The third component gathered all scales coding idealization. Inter-relations among the components were consistent with attachment theory, and respondents’ scores for all three components differed significantly across the four categorical attachment classifications. Affect regulation of negative emotion through anger and through derogation co-occurred, and was distinct from regulation through maintaining a belief that things are better than they appear (idealization). These two affect regulation strategies appeared commonly when reflective functioning, and an organized self-perception, and positive peer relations were less in evidence. The multi-dimensional FFI coding system appears to measure successfully these diverse features of the child’s narrative provided in response to the interview. Overall, our findings support the construct validity of the FFI and provide further evidence of its usefulness for assessing attachment in middle childhood and early adolescence.     

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.     

Predictors of treatment outcome for youth receiving intensive residential treatment for obsessive–compulsive disorder (OCD)

ABSTRACT

Little is known about the predictors of outcome from intensive residential treatment of OCD. This study aimed to examine age, gender, and baseline OCD severity, as well as measures of comorbid anxiety and depressive, internalizing/externalizing, and inattention symptoms, as predictors of treatment outcome in adolescents receiving intensive residential treatment for OCD.

The sample comprised 314 adolescents aged 13–17 years with treatment-resistant OCD and a Children’s Yale–Brown Obsessive–Compulsive Scale Self-Report (CY-BOCS-SR) total score ≥16. Bivariate and multiple regression models were used to evaluate the predictors of continuous OCD severity outcome and treatment response.

Results of the bivariate regression analyses of predictors demonstrated that length of treatment, pre-treatment OCD severity, and symptoms of anxiety and depression significantly predicted post-treatment OCD severity, while only symptoms of depression and anxiety predicted treatment response. When including all predictors in the same model, only baseline OCD severity remained a significant predictor of post-treatment OCD severity, and none of the assessed variables significantly predicted treatment response.

Results indicate that low pre-treatment OCD severity predicts lower OCD severity following treatment, although it did not predict treatment response.     

Friend or foe? Postdivorce hostility among recently divorced individuals

High levels of hostility often occur during and postdivorce and may significantly affect the quality of life, parent–child relationships, and social functioning of divorcees. Moreover, hostility may predict aggressive and violent behavior. This study sought to (a) compare average general hostility levels of a large sample of Danish divorcees to the norms of the general adult Danish population, (b) compare general hostility levels between male and female divorcees, and (c) investigate the explanatory value of various sociodemographic and divorce-related factors on postdivorce general hostility and whether these factors differ across gender. Cross-sectional baseline data (N = 1,856) from a larger randomized controlled trial study was used in this study. Normative data from a general sample of Danish adults (N = 2,040) was used for comparisons of hostility levels between our study sample and the Danish background population. This study found that male and female divorcees did not report significantly different hostility levels. However, participants reported significantly higher hostility levels postdivorce than the comparative Danish norm sample. Significant predictors of postdivorce hostility were lower age, lower educational level, infidelity as a reason for divorce, higher degree of postdivorce conflict, worse communication with the former spouse, the former spouse as the initiator of the divorce, and new partner status with neither divorcees having a new partner, or only the former spouse having a new partner. The predictive strength of the factors did not differ across gender. The findings may be especially relevant for interventions targeting problematic outcomes postdivorce (e.g., preventing aggressive behavior).     

Comparing negative emotion differentiation in young and older individuals: A picture-based study

Life span theories suggest that emotional experiences become more complex (i.e., nuanced and differentiated) with age. Theoretically, the cause of this increased complexity has been proposed to be age-related changes in life contexts such as goals and daily stressors. Consequently, age may not affect emotional complexity in settings where the influence of age-specific life contexts is reduced. However, this hypothesis has yet to be explored. In the present study, we investigated one aspect of emotional complexity, namely emotion differentiation. Extending previous research, we assessed age-group differences in negative emotion differentiation between young and older adults in a controlled experimental setting. A sample of 114 young and 132 older adults rated their emotional response to 34 negative pictures according to intensity of four negative emotions. Based on these ratings, two indicators of emotion differentiation were calculated. The results revealed no significant age-group differences in negative emotion differentiation. The findings indicate stability in negative emotion differentiation with increasing age when the influence of life context is reduced. The findings are consistent with life span theories suggesting that developmental changes in emotional complexity occur largely as a result of age-related changes in life contexts rather than more stable age-related changes in individual characteristics.
