Untersuchungen zur psychischen Wirkung eines zentralen Stimulans nach verschiedenen Graden psychischer Beanspruchung

Zusammenfassung Ziel der Arbeit war die Untersuchung der Frage, ob die Wirkungsintensität eines zentralen Stimulans (2-Äthyl-amino-3-phenyl-norcamphan) abhängig ist vom Grad vorgegangener psychischer Beanspruchung.Nach einem Meßwiederholungsplan mit systematischer Permutation der Bedingungen nahm jeder von 16 Probanden an vier Versuchen teil. An einem Versuch wurde Placebo verabreicht, an drei Versuchen 2-Äthyl-amino-3-phenyl-norcamphan. Dabei wurde das Präparat entweder 1 Stunde, 3 oder 5 Stunden nach Beginn des Versuches (Beanspruchung) verabreicht.In mehreren psychologischen Leistungsvariablen und zwei Methoden zur Erfassung von subjektiven Veränderungen wurde untersucht, inwieweit die Hypothese einer Proportionalität zwischen Wirkungsintensität und Grad der Ausgangsermüdung verifiziert ist.Die Ergebnisse zeigen, daß in leistungsmäßiger Hinsicht diese Hypothese als falsifiziert anzusehen ist. Lediglich in subjektiv-erlebnismäßiger Hinsicht besteht eine gewisse Proportionalität.     

Everyday temptations: an experience sampling study of desire, conflict, and self-control

How often and how strongly do people experience desires, to what extent do their desires conflict with other goals, and how often and successfully do people exercise self-control to resist their desires? To investigate desire and attempts to control desire in everyday life, we conducted a large-scale experience sampling study based on a conceptual framework integrating desire strength, conflict, resistance (use of self-control), and behavior enactment. A sample of 205 adults wore beepers for a week. They furnished 7,827 reports of desire episodes and completed personality measures of behavioral inhibition system/behavior activation system (BIS/BAS) sensitivity, trait self-control, perfectionism, and narcissistic entitlement. Results suggest that desires are frequent, variable in intensity, and largely unproblematic. Those urges that do conflict with other goals tend to elicit resistance, with uneven success. Desire strength, conflict, resistance, and self-regulatory success were moderated in multiple ways by personality variables as well as by situational and interpersonal factors such as alcohol consumption, the mere presence of others, and the presence of others who already had enacted the desire in question. Whereas personality generally had a stronger impact on the dimensions of desire that emerged early in its course (desire strength and conflict), situational factors showed relatively more influence on components later in the process (resistance and behavior enactment). In total, these findings offer a novel and detailed perspective on the nature of everyday desires and associated self-regulatory successes and failures.     

When East meets West: a longitudinal examination of the relationship between group relative deprivation and intergroup contact in reunified Germany

Intergroup contact and group relative deprivation have both been shown to play a key role in the understanding of intergroup relations. Nevertheless, we know little about their causal relationship. In order to shed some light on the directionality and causality of the relationship between intergroup contact and group relative deprivation, we analysed responses by East and West Germans from k= 97 different cities, collected 6 (N(T)(1) = 1,001), 8 (N(T)(2) = 747), and 10 years (N(T)(3) = 565) after reunification. Multi-level cross-lagged analyses showed that group relative deprivation at T1 led to more (rather than less) intergroup contact between East and West Germans 2 years as well as 4 years later. We found no evidence for the reverse causal relationship, or moderation by group membership. Furthermore, admiration mediated the positive effect of relative deprivation on intergroup contact for both East and West Germans. This intriguing finding suggests that intergroup contact may be used as a proactive identity management strategy by members of both minority and majority groups.     

Reinstatement of fear in humans: autonomic and experiential responses in a differential conditioning paradigm

The present study investigated reinstatement of fear in humans using an aversive differential conditioning paradigm. Two neutral human face pictures were presented during habituation, acquisition, extinction, and postreinstatement phases. One picture served as a conditioned stimulus (CS) reinforced by an unconditioned stimulus (US) in the form of electrical stimulation (CS+) and the second picture as a control stimulus that was never reinforced (CS-). The prediction that in a reinstatement manipulation a previously extinguished fear response in humans can be reinstated in a reinstatement group by the mere presentation of three unpredicted electrical stimulations (USs) was tested. Participants in the control group were not exposed to unpredicted USs and no reinstatement effect was expected. Outcome measures included subjective US expectancy ratings and skin conductance responses. Results showed non-selective return of the fear response due to fear recovery associated with both CSs (CS+/CS-) in the reinstatement group. Unexpected fear recovery was observed for both CSs (CS+/CS-) in control participants. Results are discussed with respect to context conditioning, fear generalisation, and anxiety-related cognitive mechanisms underlying fear recovery after extinction.     

Mind Reading Skills and Empathy: Evidence for Nice and Nasty ToM Behaviours in School-Aged Children

We investigated the social use of theory of mind in school-aged children. The expressions Nice Theory of Mind and Nasty Theory of Mind are used to differentiate behaviours requiring a prosocial use and an antisocial use of ToM abilities respectively. Our goals was to investigate whether and how mind reading abilities and empathy affect nice and nasty ToM behaviours. One hundred and ninety-seven children who were fourth and fifth graders took part in this study. Participants were administered stories that assessed cognitive, affective or moral mental state reasoning abilities and they also completed a self-report measure of empathy. Teachers’ rating on children’s prosocial and antisocial behaviours that underpin ToM abilities led us to identify nice and nasty ToM behaviours. We found that children who engage in nasty ToM behaviour showed good abilities to understand others’ thoughts and beliefs. However, children with nice ToM behaviour showed more moral and emotional sensitivity as compared to children who engage in nasty ToM behaviour. Furthermore, the hot component of empathy is stronger in fostering prosocial behaviours and inhibiting antisocial acts than cognitive component.     

Epilepsie: Aktuelles zu Diagnostik und Therapie

Bei etwa 65 Prozent der Epilepsiepatienten kann durch eine antikonvulsive Therapie anhaltende Anfallsfreiheit erreicht werden, bei den übrigen 35 Prozent entwickelt sich eine therapieresistente beziehungsweise schwer behandelbare Epilepsie. Für manche Patienten mit therapieresistenten Epilepsien stellt die Epilepsiechirurgie eine effektive und sichere Behandlungsoption dar. Die wichtigsten Behandlungsziele sind neben der optimalen Anfallskontrolle (im Idealfall Anfallsfreiheit) die gute Vertr?glichkeit der medikament?sen Therapie, die Vermeidung von chronischen Nebenwirkungen, die einfache Handhabung der Medikation für Arzt und Patient, die günstige Beeinflussung von mit der Epilepsie h?ufig assoziierten Begleiterkrankungen sowie die Berücksichtigung der Bedürfnisse spezieller Patientengruppen. Generell sollte somit eine m?glichst individualisierte Therapie erfolgen, die auf die Bedürfnisse des jeweiligen Patienten abgestimmt ist.     

Sex differences in face cognition

Although there is abundant evidence for female superiority in Face Cognition (FC), a number of questions regarding sex differences remain to be addressed. Here we report a reanalysis of data on the level of latent factors, modeled on the basis of an extensive test battery applied to three samples of over 800 adults in all. In independent samples the measurement structure of FC was invariant for both sexes, indicating that the measurement of the construct does not depend on the context variable sex, and investigating mean performance differences will not be biased by measurement issues — a neglected aspect in previous studies. We confirmed female superiority for face perception (FP) and face memory (FM). For the first time we could show that these sex differences prevailed after accounting for sex differences in broadly measured general cognitive functioning and in object perception. Across adult age, sex differences in FM increased due to the rapid decline of this ability in men, whereas performance in women remained stable across adult age. Self-reported social involvement and things-oriented activities moderated sex-differences in FM. Results show that sex differences are salient at the level of specific FC constructs and that they can be partially explained by social involvement.     

Reflections on the Theory-Practice Gap in Cognitive Behavior Therapy

The papers in this special series, edited by Pilecki and McKay (2013--this issue), are devoted to examining the theory-practice gap in cognitive-behavior therapy (CBT). A gap between theory and practice can occur at more than one level. First, there exists a substantial and concerning gap between the theories and interventions supported by research and those being offered to patients in the community (i.e., research-practice gap). There is also a growing concern in the field that the techniques and procedures that characterize cognitive-behavioral therapies are becoming increasingly divorced from underlying theories (i.e., theory-procedure gap). In the present commentary we hope to summarize and comment on some of the themes, issues, and future directions raised by our contributors.     

Impervious and intrusive: The impenetrable object in transference and countertransference

The author describes an internal object that he calls the ‘impenetrable object’ which has two characteristics: being impervious to the projections from the patient and being intrusive, i.e. projecting into the patient. It arises out of an early relationship with a mother who may be generally disturbed or traumatized so that she is unable to take in or tolerate the child's projections and may use the child as a receptacle for her own projections. He links the concept of an impenetrable object with other concepts such as Williams's ‘reversal of the container–contained relationship’ and Green's ‘dead mother’. If such an object dominates the patient's internal world, it can lead to severe difficulties in the analytic process. Interpretations may be experienced as violent projections from the analyst which the patient has to ward off and the analyst may enact an impervious or intrusive object in various ways. The author describes a case in which such dynamics played a significant role. He argues that intensive work in the countertransference is required to detect subtle enactments and allow a shift in the analyst, which in turn can enable change in the patient. He gives clinical material that demonstrates such work by the analyst and illustrates the shift from an impenetrable object to a more permeable one in the patient's internal world.
