Dazu wird folgendes Procedere vorgeschlagen: (1) {\"u}berpr{\"u}fe, ob in allen Zentren die Randomisierungsbedingungen eingehalten wurden, (2) {\"u}berpr{\"u}fe, ob die Zentren homogen bezogen auf die eingebrachten Schichtvariablen (z.B. Geschlecht, Indikation) sind und (3) {\"u}berpr{\"u}fe, ob die Zentren homogen sind bezogen auf die Wechselwirkungen zwischen den eingebrachten faktoriellen Variablen. Es wird gezeigt, daß vor allem Forderung (3) f{\"u}r die Interpretationsf{\"a}higkeit der Ergebnisse von entscheidender Bedeutung ist.

It is shown that decreased physical distance as well as increased intimacy yields high activation, both in psychological measures (experienced stress) and in pulse frequences. One result (highly significant and replicated in other experiments) was paradoxical: when Ss had to caress the face of a heterosexual vis-a-vis, they reported high experienced stress, but pulse frequences dropped rapidely below the resting pulse. Some suggestions are made to explain these findings. The question arises whether an autonomic somatic process, induced by social Stimulation, but independent of the cognitive coping is responsible for these results.}, subject = {Psychologie}, language = {de} } @inproceedings{KohnenKrueger1981, author = {Kohnen, Ralph and Kr{\"u}ger, Hans-Peter}, title = {Soziale Situationen als experimentelle Bedingungen der Pharmakopsychologie}, url = {http://nbn-resolving.de/urn:nbn:de:bvb:20-opus-86041}, year = {1981}, abstract = {Summary (Social Situations as Experimental Conditions in Psychopharmacology): To reduce a great variability of drug effects in healthy subjects, stress conditions are used often in pharmacopsychology. However, empirical results show that the desired stress effects are failing. This paper suggests to realize social stress Situations as interactions between subjects, expecting higher challenging effects than experimentator-subject-interactions, usually used in experimental designs. Two experimental studies are reported: the call-upsituation and the group-therapy situation. The experimental effects were measured by changes of pulse-frequencies. The results indicate that in the two situations high and low dosages of tranquilizing drugs lead to comparable (and so predictable) effects only, if a Situation is high challenging for the experimental subjects. The call-up situation, which proves performance, challenges male subjects highly. The emotional or social competence demanding group-therapy situation is a high challenging situation for warnen. It is concluded that no situation is stressing a person generally. Depending from personality characteristics, differential stressor effects appear. Consequences for experiments in pharmacopsychology are discussed.}, subject = {Soziale Situation}, language = {de} } @inproceedings{AndersSchartlScholl1981, author = {Anders, F. and Schartl, Manfred and Scholl, E.}, title = {Evaluation of environmental and hereditary factors in carcinogenesis, based on studies in Xiphophorus}, url = {http://nbn-resolving.de/urn:nbn:de:bvb:20-opus-72741}, year = {1981}, abstract = {Neoplasia in Xiphophorus can be classified into a) a large group that is triggered by carcinogens; b) a large group triggered by promoters; c) a small group that develops "spontaneously" following interpopulational and interracial hybridizations; and d) a small group that develops "spontaneously" following germ line mutation.
