Title / Titel Consequences of psychomotor retardation in primary depression and Parkinson disease: A comparative study of interpersonal responsiveness in dyadic interactions (Part 1) and the domain of executive functions (Part 2)
PDF Abstract (PDF, 14 KB)
Summary / Zusammenfassung Theoretical work and several experimental studies indicate an adverse nature of depressed persons' interactions with strangers that can lead to rejection or actual avoidance of depressed people. Recent research evidence suggests that part of this effect in the interpersonal field during dyadic interactions is mediated by psychomotor retardation. Whether retardation of hypokinetic movement disorders like Parkinson disease exerts similar effects remains an open question for research.
Part 1 of this research project aims at measuring behavioral effects and interpersonal consequences (e.g. inter-personal slowing down) of depressive retardation during dyadic interaction. Consistent with Widlöcher et al. (1983, 1989) hypothesis of a global alteration of the temporal modulation of activation and responses in de-pressed states, we test the effects of depressed patients' altered interpersonal responsiveness in dyadic interacti-ons - an important element of the social skills which determine interpersonal perception (Davis, 1982). Conse-quently, depressed persons are unable to answer demands by others in an expected way. Therefore, we develo-ped a method of videoanalysis allowing us to measure sequential patterns of behavioral variables for the regula-tion of the flow of communication in order to measure altered responsiveness of depressed people in dyadic in-teractions with a stranger. This new method also allows us to examine possible consequences of this behavioral alterations in the interpersonal field (e.g. interpersonal attributions and attraction). Depressed patients will be compared with healthy control persons and Parkinson disease patients.
In part 2 time-related behavioral variables from part 1 will be correlated with depressed persons' performance on neuropsychological tests of executive functions in order to test our hypothesis of a general psychomotor and cognitive slowing of action activation in depressed patients.
The results are being prepared for publication.
