It was analyzed whether an embodied conversational agent (ECA) has specific advantages when employed with privacy invading technologies such as a biometric security system. The study compares the effects of an ECA interface with the effects of conventional text-based and voice-based interfaces on user acceptance and usability. An additional variable was whether the biometric system falsely rejected the user twice or whether it directly accepted him/her. Results of the 2 × 3 between-subjects design indicated that, although overall the text interface is rated most positive, voice and ECA yield distinct social effects: They have more advantageous consequences when problems arise – i.e., when the user is rejected repeatedly. The implications for social psychology in terms of applicability of new research methods as well as insights concerning fundamental research are discussed.

Abstract. In this paper, we present a study on collaborative capability of teams in three network organizations in Austria and Switzerland. So far, collaborative capability was mostly conceptualized on organizational or individual level as a set of attributes that actors employ to collaborate successfully. We found that this view of collaborative capability has to be enlarged. Collaborative capability of teams is characterized by at least two components: an attribute-based perspective that focuses on capabilities of single actors or organizations, and a perspective on group dynamics, that describes how teams develop collaborative capability. We discuss our findings with regard to the different organizational settings of the networks analyzed and the current literature on collaborative capability and network organizations.
