No deficits in nonverbal memory, metamemory and internal as well as external source memory in obsessive-compulsive disorder (OCD)

A large body of literature suggests that some symptoms of obsessive-compulsive disorder (OCD) result from mnemonic dysfunctions. The present study tested various formulations of the memory deficit hypothesis considering important moderators, such as depression and response slowing. Thirty-two OCD patients and 32 healthy controls were presented verbal or nonverbal instructions for actions (e.g. simple gestures). These actions should either be performed or imagined. For recognition, previously presented as well as novel actions were displayed. Decisions had to be made whether an action was previously displayed (verbally vs. nonverbally) or not and whether an action was performed or imagined (internal source memory). Moreover, both judgments required confidence ratings. Groups did not differ in memory accuracy and metamemory for verbally presented material. Patients displayed some impairment for nonverbally presented material and imagined instructions, which, however, could be fully accounted for by response slowing and depressive symptoms. The study challenges the view that primary memory deficits underlie OCD or any of its subtypes. We claim that research should move forward from the mere study of objective impairment to the assessment of cognitive performance in conjunction with personality traits such as inflated responsibility.     

Die Kindestötung unter strafrechtlichen Aspekten

It is outlined that infanticide has been assessed in many different ways in the history of criminal law. Special emphasis is put on the former § 217 StGB of the German Penal Code. Then a presentation of the relevant provisions of the current German penal law and their application in individual cases is given.     

The cognitive representation of political personalities. A cross-cultural comparison(1)

The cognitive representation of salient political personalities was studied in a British and a German student sample, using a multi-dimensional scaling (MDS) procedure. Separate MDS analyses for the two samples yielded a readily interpetable three dimensional stimulus space in each case. These cognitive spaces for political figures were interpreted as reflecting the attributes of political potency, evaluation and intelligence in the case of the British sample, and evaluation, conservatism and political potency in the case of the German sample. An additional joint analysis of data from both subject groups indicated significant cross-cultural differences in the cognitive representations of political leaders. The results were discussed in terms of the socio-cultural differences between the two subsamples, and the utility of a multi-dimensional approach to political perception and behaviour.     

Information seeking of high- and low-anxiety subjects after receiving positive and negative self-relevant feedback

The present paper reports an experiment in which subjects received fictitious intelligence test feedback that was either negatively or positively discrepant with their self-evaluation. They were then given an opportunity to choose among several articles containing information that either derogated intelligence tests (test-disparaging information) or argued for their validity (test-supporting information). The main finding of this study consists of an interaction between the personality factor anxiety and the feedback variable: High-anxiety subjects prefer test-disparaging information significantly more in the negative feedback condition than in the positive feedback condition, whereas low-anxiety subjects show no difference in preference for test-related information as a function of the feedback condition. These results are in line with past theoretical reasoning and experimental findings showing that high-anxiety subjects feel more threatened by negative self-relevant feedback than do low-anxiety subjects.     

Reactions to success and failure in public and in private conditions

It was shown that the reaction to success and failure differs when it is communicated publicly or privately and when the reaction to success and failure is measured publicly or privately. Participants took an intelligence test and received fictitious results which were positively or negatively discrepant from the average. The dependent variable was the evaluation of the intelligence test. It was found that when the subject's evaluation of the test was private, the test was evaluated more positively under public than under private success. However, it was evaluated more negatively under public than under private failure. Under public success feedback the test was evaluated more positively under private than under public evaluation, whereas under public failure feedback the effect was reversed. The results are interpreted in terms of a self-presentation model and were discussed in the context of earlier research within the field of interpersonal relations.     

Psychobiology of altered states of consciousness

The article reviews the current knowledge regarding altered states of consciousness (ASC) (a) occurring spontaneously, (b) evoked by physical and physiological stimulation, (c) induced by psychological means, and (d) caused by diseases. The emphasis is laid on psychological and neurobiological approaches. The phenomenological analysis of the multiple ASC resulted in 4 dimensions by which they can be characterized: activation, awareness span, self-awareness, and sensory dynamics. The neurophysiological approach revealed that the different states of consciousness are mainly brought about by a compromised brain structure, transient changes in brain dynamics (disconnectivity), and neurochemical and metabolic processes. Besides these severe alterations, environmental stimuli, mental practices, and techniques of self-control can also temporarily alter brain functioning and conscious experience.     

The facial pattern of disgust, appetence, excited joy and relaxed joy: an improved facial EMG study

The purpose of the study was to investigate the facial muscle pattern of disgust in comparison to appetence and joy, using an improved facial EMG method. We analyzed the activity of nine facial muscles in forty healthy subjects. The subject group was randomly divided into two groups (oversaturated vs. hungry) of ten women and ten men each. Four different emotions (disgust, appetence, excited-joy and relaxed-joy) were induced by showing pictures from the IAPS. Pre-visible facial muscle activity was measured with a new facial EMG. A Visual Analog Scale (VAS) was established. Disgust is represented by a specific facial muscle pattern involving M.corrugator and M.orbicularis oculi, clearly distinguishing it from the facial patterns of appetence and joy. The intensity of disgust is stronger in a state of hunger than under oversaturation and is altogether stronger in females than in males. Our findings indicate the possibility to explore the entire emotion system successfully through a state-of-the-art psychophysiological method like our EMG device.
