  abstract  = {Internal characteristics such as depressed mood, anxiety and general negative emotions are accompanied, particularly during depressive illness, by changes in observable behaviour. Accordingly, the following questions may be examined: are intra-individual changes in speech and gaze behaviour related to changes in the internal psychopathological state? Further, do these changes occur synchronously to changes in the state of subjective well-being? A longitudinal study was made on depressed patients. Their behaviour was observed during standardised interviews and diagnostic-therapeutic discussions held at regu~ lar intervals. Various speech and gaze parameters were examined with respect to their coordination and their relationship to the subjective state of well-being. Considerable variation was found in the temporal relationship amongst these variables. The results are discussed with respect to the relevance of speech parameters and the coordination of verbal and nonverbal behaviour as indicators of the psychopathological condition.},

  abstract  = {A substantial literature exists on the coordination of speaking and looking behaviour and their significance as indicators for the production and reception of social information. Within this framework, the temporal organisation of such behaviour has been 'shown to reflect both the coordination within the individual and between participants in a situation. In this paper, it is proposed that observed behavioural sequences may be formally described by rules of syntax, thus implying the likelihood of structural organisation as opposed to, for example, linear time dependence between behavioural states. This being the case, differing sets of rules and grammars respectively can be expected for various social situations. Clinical interviews and discu~sions between couples on a topic of marital conflict were analysed, the on-off patterns of speech and gaze being taken as data. The resulting behavioural repertoire was regarded, in the sense of a formal grammar, as the terminal vocabulary. A set of rewriting rules was determined and their associated probabilities inferred. The situational conditions were found to be reflectedin the syntactic features of the grammatical model - the terminal vocabulary, the production rules and the production probabilities.},

  abstract  = {Validit{\"a}t und Reliabilit{\"a}t der Sprechkodierung einer Beobachtergruppe wurden in Abh{\"a}ngigkeit von der zeitlichen Aufl{\"o}sung untersucht. Die Validit{\"a}t wurde anhand der {\"U}bereinstimmung der Beobachter mit einem automatischen Sprachdetektor berechnet. Die Reliabilit{\"a}tswerte f{\"u}r die Kodierung von Sprechen und Blikken ergaben sich aus der {\"U}bereinstimmung der Beobachter untereinander. Im wesentlichen zeigten sich folgende Ergebnisse: 1. Die Validit{\"a}t/Reliabilit{\"a}t der Sprechkodierung ist eine monotone, nichtlineare Funktion der gew{\"a}hlten Aufl{\"o}sung. Die systematischen Fehler, die auf Latenz und Tr{\"a}gheit der menschlichen Beobachter zur{\"u}ckgehen, werden bei einer Aufl{\"o}sung von 400 msec nahezu vollst{\"a}ndig unterdr{\"u}ckt. 2. Weder bei der Erfassung des Sprech- noch des Blickverhaltens lassen sich Anzeichen f{\"u}r Observer-Drift feststellen. Trainierte und untrainierte Beobachter unterscheiden sich nicht signifikant. 3. Die Kodierung des Sprechverhaltens ist geringf{\"u}gig reliabler als die des Blickverhaltens. Dieser Unterschied kann in der Praxis vernachl{\"a}ssigt werden.},
