Neuro-cognitive basis of depression and effectiveness of brief psychological interventions

 

Research Description

In this research project we, first of all, study the neuro-cognitive functions in depressive and non-depressive control participants in order to find possible endophenotypes of depression. These internal but measurable components are aimed to reveal by applying electrophysiological (event-related potential) and eye-tracking experiments. Second, we will measure the effectiveness of brief psychological interventions (based on acceptance and commitment therapy) for depression. Based on two different levels of data, psychological inventory and brain response data, we will describe to whom these interventions would be best suitable. We assume that in the future the endophenotypes of depression may allow the prediction of the course of remission or relapse, and the accurate and cost-effective individual-based tailoring of the most appropriate type of therapy for each patient. The methods we apply in the neuro-cognitive experiments are mostly the same we have applied in the research project “Behavioral and electrophysiological research of visual cognition”.
