Theoretical background, measurement, and clinical validity N2 - Der Begriff "speech chronemics" wird eingeführt, um eine Forschungsrichtung zu charakterisieren, die aus den physikalischen Qualitäten des Sprachsignals lediglich das Muster von "an" ("Sprechen") und "aus" ("Pausieren") herauszieht. Die Forschungen zu diesen on-off Mustern lassen sich in die methodischen Dimensionen "zeitliche Einheit", "Zahl der Sprecher" und "Art der prosodischen Maße" gliedern. Es wird gezeigt, daß die Entscheidung eines Untersuchers für eine bestimmte Methodik das Ergebnis seiner Untersuchung nicht unerheblich vorausbestimmt. Es wird dann mit dem Logoport ein neues tragbares Meßinstrument vorgestellt, das es erlaubt, das Sprechverhalten von Probanden bis zu 24 Stunden lang in deren normaler Umgebung aufzuzeichnen. Es werden zwei Experimente beschrieben. Im ersten wird gezeigt, daß die Messung von Artiku1ationspausen valide den psychophysiologischen Aktivierungsstatus abbilden kann. In der zweiten Studie wird die soziotrope Wirksamkeit einer neuen betablockierenden Substanz aufgezeigt: in einer Langzeitstudie verbesserte sich das Interaktionsverhalten von Probanden, die sich sozial schwer tun, im Vergleich zu Plazebo und zum Verhalten von Personen ohne solche Schwierigkeiten. Schließlich wird mit Blick auf neue Studien die Wichtigkeit einer überlegten theoretischen Einbettung und einer Standardisierung von situativen und methodischen Merkmalen betont. N2 - The term "speech chronemics" is introduced to characterize a research strategy which extracts from the physical qualities of the speech signal only the pattern of ons ("speaking") and offs ("pausing"). The research in this field can be structured into the methodological dimension "unit of time", "number of speakers", and "quality of the prosodic measures". It is shown that a researcher's actual decision for one method largely determines the outcome of his study. Then, with the Logoport a new portable measurement device is presented. It enables the researcher to study speaking behavior over long periods of time (up to 24 hours) in the normal environment of his subjects. Two experiments are reported. The first shows the validity of articulation pauses for variations in the physiological state of the organism. The second study proves a new betablocking agent to have sociotropic effects: in a long-term trial socially high-strung subjects showed an improved interaction behavior (compared to placebo and socially easy-going persons) in their everyday life. Finally, the need for a comprehensive theoretical foundation and for standardization of measurement situations and methods is emphasized.

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.

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.
