Cohort differences in cognitive aging and terminal decline in the Seattle Longitudinal Study

Life span researchers have long been interested in how and why fundamental aspects of human ontogeny differ between cohorts of people who have lived through different historical epochs. When examined at the same age, later born cohorts are often cognitively and physically fitter than earlier born cohorts. Less is known, however, about cohort differences in the rate of cognitive aging and if, at the very end of life, pervasive mortality-related processes overshadow and minimize cohort differences. We used data on 5 primary mental abilities from the Seattle Longitudinal Study (Schaie, 2005) to compare both age-related and mortality-related changes between earlier born cohorts (1886-1913) and later born cohorts (1914-1948). Our models covary for several individual and cohort differences in central indicators of life expectancy, education, health, and gender. Age-related growth models corroborate and extend earlier findings by documenting level differences at age 70 of up to 0.50 SD and less steep rates of cognitive aging on all abilities between 50 and 80 years of age favoring the later born cohort. In contrast, mortality-related models provide limited support for positive cohort differences. The later born cohort showed steeper mortality-related declines. We discuss possible reasons why often reported positive secular trends in age-related processes may not generalize to the vulnerable segment of the population that is close to death and suggest routes for further inquiry.     

Profiling active and passive nonrespondents to an organizational survey

In this field study (N = 405) population profiling was introduced to examine general and specific classes of nonresponse (active vs. passive) to a satisfaction survey. The active nonrespondent group (i.e., purposeful nonresponders) was relatively small (approximately 15%). Active nonrespondents, in comparison with respondents, were less satisfied with the entity sponsoring the survey and were less conscientious. Passive nonrespondents (e.g., forgot), who represented the majority of nonrespondents, were attitudinally similar to respondents but differed with regard to personality. Nonresponse bias does not appear to be a substantive concern for satisfaction type variables--the typical core of an organizational survey. If the survey concerns topics strongly related to Conscientiousness and Agreeableness, the respondent sample may not be representative of the population.     

Moody and thin-skinned? The interplay of neuroticism and momentary affect in older romantic couples

Neuroticism is associated with heightened reactivity to social stressors. However, little is known about the micro-processes through which neuroticism shapes – and is shaped by – affective experiences in close relationships. We examine the extent to which momentary affect is coupled with one’s relationship partner, whether the strength of this coupling differs depending on levels of neuroticism, and whether this coupling and partner’s overall level of positive or negative affect prospectively contribute to differential (rank-order) changes in neuroticism. Older couples (N = 82, aged 67–93 years) rated their momentary affect six times per day for one week and provided ratings of trait neuroticism at baseline and 18 months later. Multilevel models revealed that among individuals high in neuroticism, individual positive affect was more closely coupled with partner positive affect compared with individuals low in neuroticism. Moreover, neuroticism decreased over time in those participants who showed a higher degree of coupling with partner positive affect and also had a partner with higher overall positive affect. In contrast, neuroticism increased in individuals whose partner had lower overall positive affect. Similar effects were not observed for negative affect. Our findings highlight how relationship partners contribute to daily affective experiences and longer-term changes in neuroticism.     

Linking Job Work Hours to Women’s Physical Health: The Role of Perceived Unfairness and Household Work Hours

Although the relationship between job work hours and women’s physical health has been examined, limited empirical research examines the family demand conditions that explain this relationship. Given the challenge of integrating work and family demands, we examine the boundary conditions under which job hours relate to women’s physical health by integrating the influences of household work hours, perceived unfairness of division of household labor, and traditional gender ideology. Using a large, multi-national archival dataset, our results show that women working long job hours are more likely to report decreased physical health and that this relationship is moderated by the hours and fairness perceptions of household labor: The lowest physical health was observed at high job hours and high household hours and also when women felt that they did less than their fair share of household labor. However, looking at the slopes of these relationships, the negative relationship between job hours and physical health was stronger when women worked lower household hours or felt that they contributed less than their fair share of household labor—suggesting that maintaining a contribution to household labor might be important for working women. Furthermore, these results suggest that policy and organizational interventions aimed at supporting women’s physical health could take their household labor contributions and fairness perceptions into account when assessing the negative impact of high job work hours.     

Developing multiple identifications through different social interactions at work

The question of how employees’ identifications with various foci at work (e.g., team, supervisor, or profession) develop and how they can be managed actively still remains largely unanswered. This is surprising, given the previously demonstrated benefits of employees’ identifications for organizational outcomes. Building on the social validation framework, we propose that changes in different social interactions (social support and effective feedback from supervisors and co-workers) over time are apt to socially validate different provisional selves and thereby differentially foster identification with the supervisor, the team, and the profession. In a longitudinal study of 212 apprentices, who are newcomers to both the organization and the profession, we test this idea using latent change scores in a structural equation modelling approach. Supporting our hypotheses, we show that changes in social support from supervisors and co-workers are related to changes in supervisor and team identification. Increased feedback from co-workers, but not from supervisors, predicted increased professional identification.     

Views on Quality of Life Differ Between Alcohol Related Brain Damaged Individuals and Their Healthcare Professionals

Measuring quality of life (QoL) in alcohol related brain damaged individuals (ARBDs) is challenging, mostly because patients are characterized by important cognitive impairments and are generally unaware of their defects. However, quality of life assessments are essential to help inform care and rehabilitative settings; thus introducing and including views from healthcare professionals on ARBDs’ quality of life is a reasonable approach. We examine QoL and the perception of cognitive defects among ARBDs and compare them to expert appraisals by acquainted healthcare professionals. We hypothesize that ARBDs self-assessments outscore QoL expert-ratings by professionals and demonstrate an unawareness of their cognitive deficits, with anosognosia being related to the QoL domains of interest. Six domains of QoL and the occurrence of cognitive problems in 14 detoxified alcoholics are investigated by means of self-ratings and expert-ratings from two acquainted healthcare professionals. Anosognosia is assessed by using difference scores between self- and expert-ratings on the manifestation of everyday executive dysfunctions. We find that ARBDs experience anosognosia (ps?<?.001) and outscore systematically expert-ratings on the investigated QoL domains (ps?<?.03). Complex patterns of relationships between self-/expert-rated QoL relate mostly negatively and moderately with anosognosia, confirming some of our assumptions and informing others. ARBDs are characterized by anosognosia and differ largely from expert’s views on patient QoL. Professionals relate compromised patient QoL to the inability of the patient to have insight of his/her dysfunctions; whereas among patients, QoL relates less strongly to anosognosia. Remaining doubts on the validity of QoL self-/expert-ratings in ARBDs are discussed.     

Synaptic adaptation and odor-background segmentation

Habituation is a form of non-associative memory that plays an important role in filtering stable or redundant inputs. The present study examines the contribution of habituation and cortical adaptation to odor-background segmentation. Segmentation of target odorants from background odorants is a fundamental computational requirement for the olfactory system. Recent electrophysiological data have shown that odor specific adaptation in piriform cortex neurons, mediated at least partially by synaptic adaptation between the olfactory bulb outputs and piriform cortex pyramidal cells, may provide an ideal mechanism for odor-background segmentation. This rapid synaptic adaptation acts as a filter to enhance cortical responsiveness to changing stimuli, while reducing responsiveness to static, potentially background stimuli. Using previously developed computational models of the olfactory system, we here show how synaptic adaptation at the olfactory bulb input to the piriform cortex, as demonstrated electrophysiologically, creates odor specific adaptation. We show how this known feature of olfactory cortical processing can contribute to adaptation to a background odor and to odor-background segmentation. We then show in a behavioral experiment that the odor-background segmentation is perceptually important and functions at the same time-scale as the synaptic adaptation observed between the olfactory bulb and cortex.     

Die postpartale Bindungsstörung: Eine Risikokonstellation für den Infantizid ?

Background

The effectiveness of preventive approaches in the field of child protection depends, amongst other things, upon identifying typical risk constellations of infanticide. Postpartum bonding disorder, a disorder affecting a mother’s emotional relationship with her child, is one of those risk constellations alongside other negative consequences to child development. It frequently accompanies postpartum depression, which is determined by other emotional qualities. The therapeutic response is a determinant factor for the success of preventive measures.

Method

42 mothers with postpartum disorders (25 depressive, 17 schizophrenic) undergoing treatment at a mother-baby-unit were examined for bonding disorders and the therapeutic response, primarily regarding the mother-child relationship. Perception of bonding, maternal self-efficacy and objectively measured parameters of mother-child interaction were the most important parameters assessed. Results. Nearly 60% of the mothers suffered from a bonding disorder. Overall, the results indicated a clear improvement in psychiatric disorder as well as in the assessed parameters for the mother-child relationship and the experience of motherhood.

Conclusions.

Maternal bonding disorders are strongly associated with postpartum depression and low maternal self-efficacy, which can lead to a risk constellation for infanticide. The data confirm the therapeutic response, thus demonstrating that early diagnosis and treatment of postpartum depression can represent a timely and effective preventive approach in the field of child protection.     

Knowing God Beyond Imagining: A Critical Appraisal of the Relation between Systematic Theology and Concrete Reality in John Milbank's Thought

John Milbank's work repeatedly invites two fundamental criticisms: he supposedly prioritises abstract thought over concrete reality, and he claims for himself a God's eye perspective on reality that is forgetful of any epistemological limits concerning a truthful human vision of the whole. Contrary to the first criticism, this article appreciates the way in which Milbank follows twentieth‐century Ressourcement theologies in relating concrete reality and abstract systematic thought. The second criticism does not disqualify Milbank's ontology, but encourages a more consequent application of this ontology in his assessment of concrete reality. As a corrective, Edward Schillebeeckx's contribution to Ressourcement theologies is revisited, as his work bears the promise of attaining an ever more limitless vision of God, via the path of contemplating concrete reality.
