Elevated disgust sensitivity in blood phobia

In order to demonstrate elevated disgust sensitivity and facilitated disgust learning in patients suffering from blood injection injury phobia, 23 phobics and 20 controls underwent an evaluative conditioning experiment. They were presented with picture pairs consisting of affectively neutral pictures (CS), which were followed by either disgust-inducing, fear-inducing, pleasant, or neutral scenes (US). During the presentation we recorded the electromyogram (EMG) of the musculus levator labii as a specific disgust indicator. Affective ratings for the pictures were determined before and after conditioning. Also, CS-US contingency verbalisation (CV) was assessed. Phobics reported a greater overall disgust sensitivity, experienced stronger feelings of disgust, and showed greater EMG responses while viewing disgust-eliciting scenes than control subjects. Evaluative conditioning occurred equally in both groups and depended on CV.     

Loneliness and social behaviours in a virtual social environment

Feeling lonely motivates people to reconnect with others, but it can also trigger a vicious cycle of cognitions and behaviours that reinforces their loneliness. In this study, we examined the behavioural consequences of loneliness in a virtual social environment. A total of 176 participants navigated a character (protagonist) through a two-dimensional browser game and rated the character's loneliness multiple times during the game. In the first part of the game, another character is introduced as the protagonist's spouse. At one point, the spouse leaves for an undetermined period of time but later returns. Immediately before this separation, higher ascribed loneliness of the protagonist was associated with more frequent interactions with the spouse. After the reunion, however, higher ascribed loneliness was associated with less frequent interactions with the spouse. Ascribed loneliness was not significantly related to the frequency of interactions with others nor to the frequency of solitary activities. These patterns held after controlling for ascribed positive affect. Participants' levels of loneliness were related to the level of ascribed loneliness only when the spouse was present but not when the spouse was absent. In sum, these findings suggest that the conditions that trigger the vicious cycle of loneliness are person- and situation-specific.     

Impact of social support on health status and life satisfaction in people with a spinal cord injury

Abstract

Purpose: Assessment of the impact of received social support on functional health status and life satisfaction in people with spinal cord injury (SCI). Design: Respondents were 176 people with SCI between 18 and 65 years of age and living in the community. Mean time after injury was 3.6 years. Problem-oriented and emotion-oriented support, received from family members, friends and relatives, and professionals were assessed with the Sources of Social Support Inventory. Health status was assessed with the Sickness Impact Profile 68 and life satisfaction with the Life Satisfaction Questionnaire. Structural equation modelling with LISREL V8 was used to study relationships of different types and sources of social support with health status and life satisfaction.Results: Emotion-oriented support led to better psychological functioning and to greater life satisfaction. In addition, emotion-oriented support from the family led to greater satisfaction with relationships and emotion-oriented support from friends and acquaintances led to less satisfaction with social life. Problem-oriented support was not clearly related to health status and life satisfaction; there was only a negative relation between problem-oriented support and satisfaction with social life. Support, problem-oriented or emotion-oriented, from health-care professionals showed no relationships with health status or life satisfaction.Conclusions: Emotion-oriented support from family members and friends was most important for people with SCI. Greater problem-oriented support appears to be related to poorer life satisfaction.     

Perceptions of Violence and Crime as Aggression by Turkish—Islamic Families in Johannesburg

This study explored perceptions of aggression of Turkish-Islamic families with adolescent children in a large South African city. Participants were from four Turkish families with adolescent children (father = 4, mothers = 4; children = 5). Data were collected via interviews and analyzed. The families considered aggression to comprise crime and violence. They also considered it a universal phenomenon.     

Merkmale eines Fehlurteils

Wrongful convictions punish accused persons who have committed no offence. Because the revision process basically only examines whether a verdict contains judicial errors and not whether it was correct or false, to correct a wrongful conviction there very often only remains the difficult way via an revision and a de novo trial. The author underlines some typical characteristics of wrongful convictions based on own experience in successful appeals which in particular involved wrongful accusations. Required are a systematic training of judges with respect to sources of error and an evaluation of errors of judgement by the Federal Ministry of Justice as a foundation for a reform of the right of appeal.     

Using high frame rate CMOS sensors for three-dimensional eye tracking

A novel three-dimensional eye tracker is described and its performance evaluated. In contrast to previous devices based on conventional video standards, the present eye tracker is based on programmable CMOS image sensors, interfaced directly to digital processing circuitry to permit real-time image acquisition and processing. This architecture provides a number of important advantages, including image sampling rates of up to 400/sec measurement, direct pixel addressing for preprocessing and acquisition, and hard-disk storage of relevant image data. The reconfigurable digital processing circuitry also facilitatesin-line optimization of the front-end, time-critical processes. The primary acquisition algorithm for tracking the pupil and other eye features is designed around the generalized Hough transform. The tracker permits comprehensive measurement of eye movement (three degrees of freedom) and head movement (six degrees of freedom), and thus provides the basis for many types of vestibulo-oculomotor and visual research. The device has been qualified by the German Space Agency (DLR) and NASA for deployment on the International Space Station. It is foreseen that the device will be used together with appropriate stimulus generators as a general purpose facility for visual and vestibular experiments. Initial verification studies with an artificial eye demonstrate a measurement resolution of better than 0.1° in all three components (i.e., system noise for each of the components measured as 0.006° H, 0.005° V, and 0.016° T. Over a range of ±20° eye rotation, linearity was found to be <0.5% (H), <0.5% (V), and <2.0% (T). A comparison with the scierai search coil technique yieldednear equivalent values for the systemnoise and the thickness of Listing’s plane.     

On the logic of psychoanalytic theory

Psychoanalytic theory shows some specific features and problems. It exists in a number of variations, according to different schools as well as cultural and subcultural conditions, with different understandings even of core concepts. Instead of producing definite knowledge, results remain uncertain. They vary in use and imply a permanent reworking of ideas and conceptions. This is the effect of the kind of theory psychoanalysis has to use. Since psychodynamics are a special kind of heterogeneous, changing, always different, emergent-in a word, autopoietic-reality, psychoanalysis cannot use the methods of a denotative theory (algorithmic reduction leading to strictly defined and formulated calculations) but has to use connotative theories. Connotative theories use open concepts which provide an active and flexible access to autopoietic reality. They are able to cope with the difference between singularities as well as with the distance between general logic and empirical reality. Problems tied to this possibility are structural fuzziness, a dependence on forms of use, multiple paradigms and difficulties in legitimation and balance of theories. This causes problems of institutionalisation. These problems are not a sign of immaturity but the normal way in which connotative theories appear and develop. They can therefore not be eliminated but only be treated in a better way.
