[Incoherence as an interaction phenomenon. Results of a single case study].

Traditionally psychiatric patients' change of topic occurring in interviews e.g. with a doctor are construed as a psychopathologically relevant type of incoherence (formal thought-disorder). In a single case study it can be shown, however, that more than half of the patient's changes of topic occur after a specific class of interactionally meaningful paraverbal features. These may be interpreted as signals of the patient's being ready to relinquish the speaker's role. Therefore, rather than interpreting this type of change of topic as thought-disordered incoherence it should be considered as a consequence of the patient's unsuccessful trying to take over the listener's role. In contrast to interactively unmarked (thought-disordered) changes of topic the occurrence of this phenomenon may be determined by the asymmetric doctor-patient relationship.

[Measuring psychophysiologic variables during conversations. Quantifying pulse volume changes].

Little is known about connections between events in verbal communication and related physiological variables. Usually used procedures in quantification of pulsevolume data are based on simplifications neglecting essential characteristics of the curve between heart beats. It is shown that the concept of interbeat-intervals (IBI) underlying conventional methods hides these characteristics putting up with a delay in time between heart beats and related verbal factors. An alternative procedure of the extraction of period and amplitude is demonstrated. A software-package is developed to transform and interactively control the analysis of the pulsevolumesignal (filtering and vector-transformation). As results quasi-continuous time series of period and amplitude of the pulsecurve are shown, tracing the shape of the curve in each cardiac cycle. Some first applications of the method in stress research are discussed. The method is appropriate especially for detecting "short time" changes of cardiac activity in naturalistic observational settings (e.g. dyadic interaction).

[Change in the self-concept of drug-dependent patients in inpatient care].

As a rule, drug addicted people show a distinctly diminished estimate of the value of their selves. It is investigated whether this estimate changes during a inpatient stay on a drug rehabilitation ward and whether the selected methods of investigation form an adequate means of evaluating the therapeutic program. It can be shown that under certain conditions (duration of stay, compliance, problem-solving ability) this is indeed the case. However, it remains an open question, whether the observed amelioration has to be viewed as a non-specific effect of the change of milieu or whether it depends on the therapeutic program offered on the ward.
