Evolution,Altruism, and the Collective Superego

ABSTRACT

Our psychoanalytic understanding of human nature is that humans are self-interested. However, this view differs with those of evolution, ethology, and neuroscience, which show evidence of a natural altruistic capacity. A theoretical foundation for this capacity can be found in psychoanalytic works, particularly those of Melanie Klein. An emerging understanding is that of an altruistic capacity that is induced and shaped by early experience and either fortified or corrupted by social pressures and mental processes. In individuals and in collective society, superego dictates can conflict with natural altruistic impulses. Recognition within psychoanalytic theory of a primary altruistic capacity is important, because we as psychoanalysts have an impact on individual and cultural self-perceptions through our treatment of patients and through our writings and therefore contribute to the shaping of values in our society.     

Hormonal contraception usage is associated with altered memory for an emotional story

Substantial evidence now documents sex-related influences on the neurobiology of emotional memory. Robust sex influences exist, for example, on the amygdala’s role in emotional memory formation, as well as on retention of central information (gist) and detail for an emotional event. Evidence also suggests that the well-documented effects of stress hormones on memory depend upon sex hormone levels. Since hormonal contraception alters sex hormone levels, and must by extension alter sex/stress hormone interactions in memory, we examined whether the use of hormonal contraception also alters memory for an emotional story. Two groups of healthy female subjects—one naturally cycling, one using hormonal contraception—viewed either a brief, emotionally arousing story, or a closely matched, but more emotionally neutral story. Each subject’s eye movements and pupil dilation changes were recorded as they viewed the story. Additionally, saliva samples were taken throughout the experimental session to examine salivary alpha-amylase, a biomarker for norepinephrine. A surprise free recall test one week later measured story memory in all subjects. Naturally cycling women exhibited enhanced memory of story details, but not of central information (gist), in the emotional compared with neutral story conditions. In contrast, women using hormonal contraception exhibited enhanced memory of gist, but not story details, in the emotional compared with neutral story conditions. Analysis of eye movements made while watching the stories indicated that the differences in memory could not be attributed either to a differential attention focus or to the degree of arousal induced by the stories in the two groups. These findings suggest that the use of hormonal contraception alters memory for an emotional event, perhaps by altering sex/stress hormone interactions in memory formation. They also suggest that further investigation of the mnemonic effects of these very widely used treatments is warranted.     

A hermeneutical sketch of memory and the immemorial

In one of his more recent works, Paul Ricoeur attempts to re-instate the philosophical discussion of memory at the very center of a more general discourse on human existence. In his exposition, Ricoeur relies upon what he himself characterizes as a phenomenology of memory. It is the aim of the present article to supplement the phenomenological account of memory discussed by Ricoeur with a hermeneutics of memory conscious of its own limitations. Such a hermeneutical supplement would not only be of complementary value but also provoke a rethinking of the relation between key concepts in the western discourse on memory, such as image, imprint, and trace. In this regard, the proposed hermeneutical reconfiguration of memory exceeds its own limitations and overflows into an investigation of the primordial passive and past ground, which motivates and allows the hermeneutical activity in the first place. Following the analyses of Emmanuel Lévinas, I will argue that this immemorial past must be conceived in terms of a responsibility that cannot be fulfilled.     

Using the Job Demands-Resources model to investigate risk perception, safety climate and job satisfaction in safety critical organizations

Using the Job Demands-Resources model (JD-R) as a theoretical framework, this study investigated the relationship between risk perception as a job demand and psychological safety climate as a job resource with regard to job satisfaction in safety critical organizations. In line with the JD-R model, it was hypothesized that high levels of risk perception is related to low job satisfaction and that a positive perception of safety climate is related to high job satisfaction. In addition, it was hypothesized that safety climate moderates the relationship between risk perception and job satisfaction. Using a sample of Norwegian offshore workers (N = 986), all three hypotheses were supported. In summary, workers who perceived high levels of risk reported lower levels of job satisfaction, whereas this effect diminished when workers perceived their safety climate as positive. Follow-up analyses revealed that this interaction was dependent on the type of risks in question. The results of this study supports the JD-R model, and provides further evidence for relationships between safety-related concepts and work-related outcomes indicating that organizations should not only develop and implement sound safety procedures to reduce the effects of risks and hazards on workers, but can also enhance other areas of organizational life through a focus on safety.     

Mindfulness-based stress reduction for patients with anxiety disorders: evaluation in a randomized controlled trial

The aim of this study was to investigate the effect of mindfulness-based stress reduction (MBSR) for patients with heterogeneous anxiety disorders. Seventy-six self-referred patients were randomized to MBSR or a waiting-list control condition. Eight participants did not complete the eight-week MBSR intervention. Treatment completers improved significantly on all outcome measures compared to controls. The completer sample showed medium to large effect sizes on measures of anxiety (Cohen’s d = 0.55–0.97), and a large effect size for symptoms of depression (Cohen’s d = 0.97). Intention-to-treat analyses yielded effect sizes in the small to moderate range (Cohen’s d = 0.32–0.76). Gains were maintained at six months follow-up. The percentage of participants reaching recovered status was highest for symptom measures of depression and anxiety, and lower for worry and trait anxiety. Mediation analyses indicated that mindfulness fully mediated changes in acute anxiety symptoms, and partially mediated changes in worry and trait anxiety. However, the present study did not find evidence of temporal precedence for the proposed mediator. In the absence of true mediation and an active control condition, it cannot be ruled out that results are due to non-specific aspects of treatment. Despite these and other limitations, we conclude that MBSR is an effective treatment for anxiety disorders and related symptomatology.     

Parental Social Bonds and Adolescents’ Convictions

Social control theory suggests that adolescents are more likely to deviate when their parental bonds are weak or broken. However, are strong bonds to unconventional parents also a protective factor, or do they increase the risk of delinquency? There is almost no empirical evidence on this puzzle. Combining Danish survey and register data (N = 2,677), this study uses fixed effects linear regressions and finds that parental convictions do not moderate the effect of strong parental social bonds. Rather, the main result shows that indirect supervision (mother knowing the adolescent’s friends) reduces the risk of child conviction, irrespective of maternal conviction.     

The force-driven harmonic oscillator model for energy-efficient locomotion in individuals with transtibial amputation

The force-driven harmonic oscillator (FDHO) model states that the driving force is minimum at the resonant period of an oscillator. By manipulating prosthetic mass, this study explored the compromise of resonant periods between the two legs in persons with unilateral traumatic transtibial amputation (TTA) at self-selected walking velocity (SSWV), with an aim to better understand the energy minimization mechanisms of walking. It was hypothesized that (1) SSWV was the most energy-efficient walking velocity (MEWV), (2) the stride period at SSWV (Ts) is a compromise between the resonant periods of the normal leg (Tn) and the prosthetic leg (Tp) when they are dissimilar. Eight subjects completed multiple-speed treadmill walking tests (at 53, 67, 80, 93, and 107 m/min) according to three mass conditions (60%, 80%, and 100% of the normal leg below-knee mass) in a random order. Oxygen consumption and stride period were measured, and SSWV was empirically determined. The MEWV, the speed with minimum energy expenditure per distance traveled, was derived from quadratic regression, and its stride period (Tm) was estimated. A theoretical compromise period (Tv) between Tn and Tp was predicted by a virtual single pendulum system based on Huygens' Law. Across different mass conditions, comparisons were made among: Ts, Tm, Tv, Tn, and Tp. Results showed that: (1) Ts was significantly different from Tm; (2) Ts was greater than both Tn and Tp; (3) no significant difference was found between Tm and Tn. Implications for amputee rehabilitation in terms of thigh muscle training and prosthesis development were discussed.
