Familienplanung junger onkologischer Patienten

Cancer patients in young adulthood are affected by the cancer diagnosis in a period of life where future parenthood or fulfilling of a potential wish to have children plays an important role. To perform fertility preserving treatment, patients should be fully informed before any treatment is carried out. The following review broaches the issue of whether and how fertility concerns are discussed in the medical consultation. Therefore, relevant papers were identified by a database search between the years 2000 and 2010. A total of 21 studies were included which focussed on physician-patient communication from the point of view of the patients or healthcare professionals. Oncologists do not routinely speak to patients about fertility issues. Both oncologists and patients expressed communication difficulties. An improvement of the medical interview concerning family planning could be achieved by provision of guidelines, training for healthcare professionals, cooperation between oncologists and reproductive medicine and the provision of educational patient material.     

The Influence of Personality on Workplace Bullying and Discrimination

This study explored the similarity of underlying personality traits of workplace bullying and discrimination. University students self-reported the frequency of bullying others in the workplace and discriminating against African Americans, homosexuals, and the obese. They completed questionnaires measuring prejudice and personality traits. The major findings were that social dominance orientation, low social desirability scores, and being male affected bullying and discrimination. Perspective taking affected bullying; and right-wing authoritarianism, anxiety, and being White affected discrimination. Prejudice influenced relations between personality and discrimination, but not bullying. It was concluded that despite strong behavioral similarities, bullying and discrimination have somewhat different underlying determinants. Certain traits make them distinct, increasing the likelihood of one choosing either a prejudice-based target or a non-prejudice-based target.     

Effect of stress induced by electrical stimulation of the hypothalamus on the electrical stability of the heart in rabbits

The influence of stress on cardiac electrical stability (CES) and chaotic dynamics of the electrical activity of the heart was studied in acute and chronic experiments in rabbits. Stress was caused by 2-3 h daily immobilization of the animals with electrical stimulation of emotiogenic centers of the hypothalamus through implanted electrodes. CES was estimated by the thresholds for ventricular arrhythmia: paroxysmal ventricular tachycardia, repeated ventricular extrasystoles and ventricular fibrillation (VF). The results showed: (i) CES in stressed rabbits was decreased significantly compared with controls; (ii) the level of chaos at the onset of VF in stressed rabbits was increased significantly compared with controls; (iii) heart rate of stressed rabbits was significantly greater than in controls; (iv) changes in CES parameters depended on whether stress was acute or chronic; (v) acute stress promoted transition of spontaneously reversible VF into spontaneously irreversible VF. Thus, stress increased the degree of disorganization of heart electrical activity and also decreased its electrical stability. The experiments indicate that stress is a destabilizing factor influencing the reversibility of heart rate disorders. The probability of such reversibility depends on whether stress is acute or chronic: acute stress is more likely to lead to irreversible spontaneous VF.     

A psychophysiological study of auditory illusions of approach and withdrawal in the context of the perceptual environment

Auditory perception of the depth of space is based mainly on spectral and amplitude changes of sound waves originating from the sound source and reaching the listener. The perceptive illusion of movement of an auditory image caused by changes in amplitude and/or frequency of the signal tone emanating from an immobile loudspeaker was studied. Analysis of data obtained from the participants revealed the diapason of combinations of amplitude and frequency changes for which the movement direction was perceived similarly by all participants, despite significantly different movement assessment criteria. Additional auditory and visual information of the conditions of radial movement (near or far fields) determined listeners' interpretation of changes in the signal parameters. The data obtained about the perception of approach and withdrawal models are evidence of the fact that the principal cues of the perception of the distance of immobile sound sources manifests similarly to that of an auditory image moving along a radial axis.     

Regression I. Experimental approaches to regression

The concept of regression is considered with an emphasis on the differences between the positions of Freud and Jung regarding its significance. The paper discusses the results of experimental analyses of individual experience dynamics (from gene expression changes and impulse neuronal activity in animals to prosocial behaviour in healthy humans at different ages, and humans in chronic pain) in those situations where regression occurs: stress, disease, learning, highly emotional states and alcohol intoxication. Common mechanisms of regression in all these situations are proposed. The mechanisms of regression can be described as reversible dedifferentiation, which is understood as a relative increase of the representation of low-differentiated (older) systems in the actualized experience. In all of the cases of dedifferentiation mentioned above, the complexity of the systemic organization of behaviour significantly decreases.     

Effects of NMDA receptor channel blockade on aggression in isolated male mice

N‐Methyl‐D ‐aspartate (NMDA) receptor antagonists are perspective candidates for medication development for a number of diseases/states that are associated with increased aggressiveness (e.g., opioid withdrawal). The prototypic NMDA receptor antagonist phencyclidine (PCP) itself is a widely abused substance and is known to elevate levels of aggression in drug users. The present study was aimed at testing several drugs that share with PCP the ability to block NMDA receptor–associated channel. The resident‐intruder procedure was used to assess drug effects on aggressive behavior in isolated male mice. Resident aggressive mice were administered NMDA channel blockers (PCP; 0.3–10 mg/kg), dizocilpine (MK‐801; 0.01–0.3 mg/kg), memantine (1–30 mg/kg), and MRZ 2/579 (0.1–5.6 mg/kg). The competitive NMDA receptor antagonist D CPPene (0.1–5.6 mg/kg) was also tested as a compound representing an alternative approach to reduce activity of NMDA receptor complex. PCP, dizocilpine, and memantine inhibited expression of aggressive behaviors only at doses that produced ataxia. The novel channel blocker MRZ 2/579 also produced ataxia at the highest dose level but failed to affect aggressiveness. Reduction in aggression with a corresponding increase in sociability was observed after administration of D ‐CPPene. Overall, the present results suggest that NMDA receptor channel blockers do not exert selective effects on aggressive behavior. Aggr. Behav. 25:381–396, 1999. © 1999 Wiley‐Liss, Inc.     

Parents' child‐rearing values and beliefs in the United States and Russia: the impact of culture and social class

Parents' values for their children and their beliefs about appropriate child‐rearing practices contribute to the ways in which they try to shape their children's development. This paper examines the values and beliefs of 71 parents (37 mothers and 34 fathers) from two cities in the United States and Russia. Half of the families were middle class (determined by education and occupation criteria) and half were working class. The results revealed no cross‐societal differences in value for self‐direction in the children; perhaps reflecting the recent economic and ideological changes in Russia. In contrast, significant social class differences, for both mothers and fathers, were found in child‐rearing values and beliefs. Middle class parents in both societies were more likely to value self‐direction and believe that children should have freedom in and around the home, whereas working class parents were more likely to believe that children should be expected to conform to rules. The results of this study underscore the role of within‐society heterogeneity, as a function of social class, in parents' values and beliefs about child‐rearing.     

Quantum-like generalization of the Bayesian updating scheme for objective and subjective mental uncertainties

In this paper we develop a general quantum-like model of decision making. Here updating of probability is based on linear algebra, the von Neumann–Lüders projection postulate, Born’s rule, and the quantum representation of the state space of a composite system by the tensor product. This quantum-like model generalizes the classical Bayesian inference in a natural way. In our approach the latter appears as a special case corresponding to the absence of relative phases in the mental state. By taking into account a possibility of the existence of correlations which are encoded in relative phases we developed a more general scheme of decision making. We discuss natural situations inducing deviations from the classical Bayesian scheme in the process of decision making by cognitive systems: in situations that can be characterized as objective and subjective mental uncertainties. Further, we discuss the problem of base rate fallacy. In our formalism, these “irrational” (non-Bayesian) inferences are represented by quantum-like bias operations acting on the mental state.     

The self regulatory effect of attentional control in modulating the relationship between attentional biases toward threat and anxiety symptoms in children

The present study examined the associations between attentional biases to threat, attentional control and anxiety in a sample of children aged 9 to 14. It was hypothesised that the association between attentional biases toward threat and anxiety might be stronger when the ability to control attention is reduced. The study employed pictures of neutral, happy and angry facial expressions as they have greater ecological value compared to words. Children completed a dot-probe task measuring attentional biases toward such stimuli. They also completed the Spence child anxiety scale for anxiety symptoms and, for attentional control, the child version of the attention control scale measuring the ability to focus and shift attention. Results of a hierarchical regression analysis showed that attentional control significantly explained anxiety. Furthermore, the interaction between attentional control and attentional biases significantly explained anxiety level. These results indicate that attentional control moderates the relation between attentional biases toward threatening facial expressions and anxiety in children. Additionally, a discussion about a possible protective role of attentional control is provided.
