T1  - Stability and Variability in Interactive Behavior as Measured by Methods of "Speech Chronemics"
N2  - Dyadic interaction is modelled os an adaptive process between personality of the partners involved and the characteristics of the theme. The theme structure and the principles which control the adaptation process are referred to as "syntality". The material of the studies reported are the speech signals of the verbal interaction reduced to an on-off pattern. In a first study individual speech behavior was found to remain stable in dyads even if partners changed. The second study showed the stability of the speech patterns for different interaction themes even if dyads changed. These apparently contradictory results are reconciled by introducing the concept of "adaptive stability". Individual speech behavior does not happen at a stable activity level, but is characterized by a constant relationship (" less" or "more") to the respective activity of the other partner.

T1  - Tranquillizer effects in an experimental analog of verbal examinations
N2  - 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.

T1  - What differentiates a differential psychopharmacology?
N2  - The methodological implications of a differential psychopharmacology are discussed. It is shown that the technique of stratifying subjects with personality scores depends on one basic assumption: the personality score is not affected by the other experimental factors. Two experiments are reported in which pre- and posttest (after the experiment) scores were measured. The pre-post-differences showed themselves to be affected by the medication. It is argued that in psychopharmacological experimentation an additional step must be included. All non-treatment factors must be examined for their stability in the course of the experiment. If they are stable, usual evaluation may take place. If changes are attributable to the treatment, personality scores must be regarded as dependent variables. They have to be evaluated together with the other observables with a multivariate model. Additionally, a procedure like this yields as "experimental differential psychology" a self-reliant contribution to the problems of differential psychology.
