EFFECTS OF LYSERGIC ACID DIETHYLAMIDE (LSD-25) ON NORMAL SUBJECTS IN A SCHIZOPHRENIA-DISCRIMINATING TEST BATTERY

Psychological tests with differing sensitivity to schizophrenic reactions were administered to eight normal subjects after oral intake of 75–100 μ g LSD-25. Control data were obtained from placebo trials. Six of the tests were chosen as sensitive to schizophrenic reactions, two tests as so-called 'hold' tests, and another test as a measure of attention, which is supposed to be reduced by LSD. Significantly lower results were obtained on four of the six sensitive tests after LSD, on one of the 'hold' tests, and on the attention test.     

Training analysis and training models

This article has the intention of giving impulses to a hopefully more creative and open-minded discussion of the function of training analysis and the kind of training model we seem to take for granted in the Scandinavian countries, the Eitingon model. I will consider some historical background data on this model as well as some historical data on the development in France which have created an alternative model of training. Especially in Sweden, there has been a stormy debate during the last years about the training analyst functions and some members have actually decided to leave our association because of this. I would like to try to shift focus from just a ‘yes-or-no-perspective’? to a broader question of our psychoanalytical society’s purpose and structure and how the training-model could sustain it.     

Applied Ethics. A Defence

Given a reasonable coherentist view of justification in ethics, applied ethics, as here conceived of, cannot only guide us, in our practical decisions, but also provide moral understanding through explanation of our moral obligations. Furthermore, applied ethics can contribute to the growth of knowledge in ethics as such. We put moral hypotheses to crucial test in individual cases. This claim is defended against the challenges from moral intuitionism and particularism.     

Different parameters support generalization and discrimination learning in Drosophila at the flight simulator

We have used a genetically tractable model system, the fruit fly Drosophila melanogaster to study the interdependence between sensory processing and associative processing on learning performance. We investigated the influence of variations in the physical and predictive properties of color stimuli in several different operant-conditioning procedures on the subsequent learning performance. These procedures included context and stimulus generalization as well as color, compound, and conditional discrimination (colors and patterns). A surprisingly complex dependence of the learning performance on the colors' physical and predictive properties emerged, which was clarified by taking into account the fly-subjective perception of the color stimuli. Based on estimates of the stimuli's color and brightness values, we propose that the different tasks are supported by different parameters of the color stimuli; generalization occurs only if the chromaticity is sufficiently similar, whereas discrimination learning relies on brightness differences.     

The Meta-Contrast Technique: relationships with personality traits and cognitive abilities in healthy women

The relationship between test results from the Meta-Contrast Technique (MCT) and self-reports from Karolinska Scales of Personality (KSP), or the State Trait Anxiety Inventory (STAI-T), was investigated in 100 healthy women. Additionally, it was investigated whether age and cognitive abilities influenced the reports of picture recognition thresholds in the MCT. The results showed no agreement between the different ways to assess anxiety and defensiveness. However, age consistently predicted later reports of the perceptual recognition thresholds A1 (the car), A2 (the face) and C-phase. The WAIS-R Digit Symbol Score predicted earlier reporting of the recognition thresholds A1 and A2, but did not predict the final criteria for correct recognition (C-phase). The KSP aggression factor only predicted an earlier report of recognition threshold A2. The absence of a simple relationship between the different ways to assess anxiety and defensiveness, and the observed relationships regarding perceptual threshold levels, corroborates previous findings.     

Is Grossarth-Maticek's coronary-prone type II an independent predictor of myocardial infarction?

Biomedical factors (hypertension, abnormal lipid metabolism, clotting factors) and behavioural factors (cigarette smoking, alcohol, fat intake) are established risk factors for ischaemic heart disease (IHD). Accumulating evidence suggests that psychosocial factors (e.g. type A behaviour, interpersonal relations and personality) also exert some influence. These factors seem to account for about 3% of the variance in IHD over and above the traditional risk factors [[Reference to Amelang, M. (1997)]. Using personality variables to predict cancer and heart disease. European Journal of Personality, 11, 319–342.] Grossarth-Maticek and colleagues have, in three prospective longitudinal studies, found that a particular type of coping in interpersonal relations (type II) predicted death from IHD over 10–15 years. The effect sizes have been of a magnitude far exceeding those reported in similar studies. This paper reports results from a cross-sectional, population-based, mailed questionnaire survey (N=5014). Using logistic regression, we did not find a significant relation between type II and myocardial infarction, when controlling for age, IHD in the family, diet, job stress and health complaints. Type II, however, had an effect on health complaints when controlling for age, IHD in the family, and job stress. A path model including an indirect effect from type II to IHD via health complaints explained 23 and 44% of the variance in health complaints and IHD, respectively. A possible explanation for results showing that type II significantly affects IHD may be that smoking is the core factor in such a way that type II is related to health complaints and smoking.

Hemispheric asymmetry and human associative learning: Interactions with attention

In a previous study (Hugdahl & Brobeck, 1986) it was shown that Pavlovian conditioning to an auditory verbal conditioned stimulus (CS) initially presented only to the left cerebral hemisphere was stronger than when the same CS was presented to the right hemisphere. This was followed up in the present study by controlling for the possibility that the effect was caused by laterally biased attention. The study was performed using the “dichotic extinction paradigm,” which consists of three different phases. During the habituation phase, the CS+ and CS- were presented binaurally and separated in time. During the acquisition phase, the CS+ was followed by a white-noise unconditioned stimulus (UCS). During the dichotic extinction phase, the CS+ and CS- were presented dichotically, i.e., simultaneous presentations on each trial. Half of the subjects had the CS+ in the right ear, and half had the CS+ in the left ear. Each group was further divided into two subgroups, with one subgroup instructed to attend only to the right ear input, and the other subgroup to attend only to the left ear input. During acquisition, larger electrodermal responses were obtained to the CS+ than to the CS-. During dichotic extinction, the CS+ right ear group showed superior resistance to extinction compared to the CS+ left ear group, with no effect of the manipulation of attention. The effect was, however, attenuated when levels of acquisition was used as covariates in an analysis of covariance. There were overall larger responses from the left hand recording.
