Drei Methoden zur Bestimmung zweiseitiger Überschreitungswahrscheinlichkeiten bei der exakten Prüfung von Vierfeldertafeln nach FISCHER-YATES werden diskutiert. An einem Beispiel wird aufgezeigt, daß diese Methoden zu verschiedenen Signifikanzentscheidungen führen können. Es werden Möglichkeiten aufgezeigt, wie diese Schwierigkeiten in der Praxis umgangen werden können.
Es wird ein neues soziometrisches Verfahren vorgeschlagen, das in seiner Grundlegung von heute üblichen Wahlverfahren abweicht. Dabei wird versucht, in einem ersten Teil die Gedanken darzustellen, die zur Formulierung der soziometrischen Fragen geführt haben. Im zweiten Teil wird der Gang der Auswertung dargestellt, der ein differenziertes Bild der untersuchten Personen zeichnen soll. Im Teil "Ergebnisse" wird am Beispiel von Extremgruppen gezeigt, was die Methode leisten kann. Schließlich werden noch mögliche Modifikationen des Verfahrens aufgezeigt.

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.
In an experimental analog of verbal examinations, the call-up situation, the effects of two dosages of a tranquillizing agent (lopirazepam) are compared to placebo treatment. 72 male and female, healthy, young volunteers have been randomly assigned to 12 groups of 6 subjects each. Pulse frequency and performance were registered. The results indicated differential drug effects which were interpreted according to the hypotheses of "differential effects of social stressors". If a situation was highly challenging for a subject, the application of a tranquillizer in an adequately high dosage enabled him to perform well in spite of or because of strong increases in pulse frequency.
