Research
The Chair’s research specialisation focuses on the interpersonal and intersubjective mechanisms that underlie the development, maintenance and psychotherapeutic change of mental disorders, and which operate dyadically across two individuals (e.g. the therapist–patient dyad).
Methods of formal modelling and empirically informed simulation are also employed to map the complexity of these psychopathological and psychotherapeutic processes and to explain them generatively (e.g. agent-based modelling). Empirical approaches include methods such as experience sampling in everyday life, video analyses of interpersonal interactions (e.g. therapy sessions) and participatory simulation paradigms in the laboratory.
Perspective
The following is a brief outline of the basic scientific perspective that shapes the research projects at the Chair of Clinical Psychology and Psychotherapy IV.
Motifs
Research at the Chair is characterised by an instrumental perspective. Accordingly, processes of experience and behaviour that enable people to actively shape their environment play an important role. These motivational processes are aimed at the long-term fulfilment of psychological needs such as autonomy, attachment and self-esteem, as well as at protecting these needs from being violated. We refer to such processes, which organise experience and behaviour, as motives.
Relationships as environments
Relationships are the aspect of the environment that is central to many psychological needs, such as attachment and autonomy, and are therefore also a key focus of the Chair’s research. On the one hand, these are interpersonal relationships that a person forms through motivated experiences and behaviour towards others, such as friendships, hierarchical relationships in the workplace, and also therapist–patient relationships. On the other hand, they involve intrapsychic relationships that a person maintains with themselves, such as self-love, self-criticism or self-exploration. At the Chair, we adopt an ecological perspective in which relationships are understood as environmental niches in which psychological needs are both met and violated. From this perspective, a friendship is a mutualistic relationship in which both parties satisfy each other’s need for attachment. This motivational, ecological approach to the dynamics of intrapsychic and interpersonal relationships underpins a large proportion of our research projects.
