The project aims to establish the theoretical need for a minimal analogue of the concept of commitment, and to develop the notion of a sense of commitment as such a minimal analogue. The project focuses on commitments within the context of joint action, i.e. within a context that is both fundamental and paradigmatic for human sociality in general. The project aims to articulate the functions that commitments fulfill, and thus also the functions that a minimal analogue of commitment should be able to fulfill, as well as the demands that can be placed upon such a minimal analogue. In developing the notion of a sense of commitment as a minimal analogue, the project focuses on emotions and action-related cues as constitutive components of the sense of commitment. Thus, it aims to conceptualize the link between commitment and emotion, and specifically to develop the concept of feeling committed as a component of the sense of commitment, as well as to experimentally test hypotheses generated by philosophical analysis. Furthermore, it aims to conceptualize the link between habitual interaction patterns and commitment, and to develop the concept of acting committed as a further component of the sense of commitment, as well as to experimentally test hypotheses generated by the philosophical analysis.
