Acute stress impairs recognition for positive words--association with stress-induced cortisol secretion

Some studies suggest that stress-induced effects of cortisol on memory are modulated by the valence of the stimuli to be learned and retrieved. The present study investigated the effect of acute stress-induced cortisol secretion on acquisition and retrieval of pleasant, unpleasant and neutral words. Sixty healthy men were randomly assigned to one of the three experimental groups. Participants were either exposed to a standardized laboratory stressor (the Trier Social Stress Test) before learning a wordlist, or before retrieval, or were not stressed. Free recall and recognition were tested 24 h later. Free recall was not affected by stress exposure. For recognition, there was no main effect of the stressor, but a main effect of valence and a valence by group interaction emerged: recognition for positive words was significantly impaired when subjects were stressed before retrieval. In addition, a positive correlation between the cortisol response and errors of commission was found. The results suggest that acute stress impairs memory for positive stimuli and that stress-induced cortisol secretion interferes with accuracy of memory retrieval, i.e. the ability to discriminate true memories from false ones.     

Traumatization of group leaders in their work with displaced persons

Displaced persons are a special, threatened group of people, participants in this war, who were suddenly forced to abandon their homes. The majority of them were, overnight, left without anything they had, some even without their closest family. They all have one thing in common: they have all lost so much. Work with such people is directed toward overcoming their feelings of loss and abandonment and preventing psychical decompensation. Groups of displaced persons temporarily sheltered in the Rijeka region have been observed to be markedly regressed, with increased sensitivity, a low degree of tolerance, great demands on society and strongly expressed projective tendencies. Therapists suffer personal traumatization in working with displaced persons. This paper describes the reactions and feelings of group leaders caused by manifestations of group dynamics in different phases of exile.     

Cognitive assessment of social anxiety: a comparison of self-report and thought listing methods

The goal of the present study was to compare 2 cognitive assessment methods for social anxiety: a thought listing and a self-report method. The focus of this study was on the convergent and divergent validity of these methods using a multi-trait multi-method approach. Furthermore, treatment sensitivity was explored. Fifty-eight patients with social phobia completed thought listings followed by 2 different social stress tasks before and after an exposure group treatment (n = 33), or following a waiting period (n = 25). One task consisted of speaking in front of 2 confederates while the other task involved initiating a conversation with an opposite-sex confederate. Two questionnaires measuring positive and negative self-statements regarding public speaking and social interactions were also completed. To compare the balance of positive and negative thoughts, the State of Mind ratio [positive thoughts/(positive+negative thoughts)] was calculated for both cognitive assessment methods. Results demonstrate that methods related to social interaction anxiety showed better convergent validity than methods related to public speaking anxiety; however, public speaking methods captured treatment effects better than methods related to social interaction anxiety. This study questions the common assumption that different cognitive assessment methods measure the same construct.     

Zur Differenzierung zwischen unsicheren und aggressiven Teilnehmern beim Gruppentraining Sozialer Kompetenzen (GSK) im Straf- und Maßregelvollzug

The cognitive-behavioural group training for social competence “GSK” [16] has proven to also be effective in the penal system [28]. The present study examines if a targeted differentiating assessment prior to the intervention and a thereon based homogeneous group composition with regard to insecure and aggressive behaviour patterns can enhance the effectiveness of the “GSK” in the penal system and in a forensic hospital unit. Altogether 48 male delinquents across both settings were therefore divided into a “homogeneous insecure” group, a “homogeneous aggressive” group and a “heterogeneous” group. Pre-post-comparisons show that the intervention is effective for all three groups and also in both settings, the penal system and the forensic hospital unit. The “homogeneous aggressive” group revealed the strongest intervention effects.     

Copying strategies and memory on the Complex Figure Test in psychiatric patients

We assessed three copying strategies on the Rey-Osterrieth Complex Figure Test among 50 psychiatric patients. The strategies were featural (detail-focused), contextual (framework-focused), and mixed. Reliable classification of each patient's copying strategy showed 7 patients used a featural and 7 patients used a contextual strategy. The remaining 36 used a mixed strategy involving both elements. Analysis indicated that patients who met DSM-III-R criteria for schizophrenia tended to use a mixed strategy. Nonschizophrenic patients also favoured the mixed approach. Moreover, when subjects were divided into groups based on their strategies, there were no differences in copying accuracy. However, the groups differed on immediate and delayed recall of the Complex Figure Test. Patients who adopted a featural strategy on the copy trial had the lowest recall scores. "Process" variables may be important in understanding neurocognitive functioning in schizophrenia; however, there is little evidence that schizophrenic patients use copying strategies consistent with lateralized impairment of brain function.     

Conception and dream material during psychoanalysis

A dream announcing her conception and describing in symbolic terms physiological processes associated with the early stages of pregnancy was reported by a female analysand 4 days after she and her husband had engaged in intercourse for the purpose of procreation. The manifest content of the dream and the associations to it are described. The assumption that conception, ordinarily a subliminal stimulus, was a somatic stimulus in this situation is explored. It is suggested that three special factors—the patient's exceptional sensitivity to internal sensations, her strong motivation to conceive, and a contributory awakening stimulus— may have made it possible for her to perceive her conception.     

Attempted clinical application of a technique for promoting robust free recall to a case of alcoholic Korsakoff's syndrome

A case study is reported which attempted to teach personal orienting information (i.e., recent history) to an amnesic male patient. The structured cuing methods reported by Kovner, Mattis, and Pass (1985, Journal of Clinical and Experimental Neuropsychology, 7, 395-411) were adopted. This involves structured presentation and cuing of target words embedded in a narrative. Some patients eventually are able to freely recall large amounts of material presented in this way. In the present case, the patient received 30 training sessions over 8 weeks. The material to be remembered was 10 target words pertaining to recent personal history. These words were embedded in accompanying storyline. The patient's immediate recall at the end of each session improved to some extent over the training period. However, delayed recall for the material remained nil throughout. Twelve months after the last training session the patient showed some "implicit" retention of the material. The findings are contrasted with Kovner et al.'s dramatic results and discussed.
