Wissen und Problemlösekompetenz
Abstract
Zusammenfassung: Nach dem Collective Information Sampling Model (Stasser & Titus, 1985) tauschen Gruppenmitglieder beim gemeinsamen Entscheiden weniger die Informationen aus, die nur ein Mitglied kennt (ungeteilte Informationen), als die Informationen, über die alle Mitglieder verfügen (geteilte Informationen). Dieser Befund ist für computervermittelt kommunizierende Gruppen besonders relevant, da in diesen Gruppen generell weniger Informationen erwähnt werden. In Studien an direkt kommunizierenden Gruppen wurde gezeigt, daß der Austausch ungeteilter Informationen durch den Hinweis auf die Expertise der Gruppenmitglieder gefördert werden kann. In Experiment 1 konnte dieser Befund für computervermittelt kommunizierende Gruppen nicht repliziert werden. In Experiment 2 wurde die Hypothese bestätigt, daß ein vermehrter Austausch ungeteilter Informationen nur dann durch den Hinweis auf Expertise erreicht werden kann, wenn Expertise als spezifisches Wissen interpretiert wird. Wird Expertise dagegen als Problemlösekompetenz verstanden, bleibt der Effekt der Expertise auf den Austausch der ungeteilten Informationen aus.
Summary: Following the Collective Information Sampling Model (Stasser & Titus, 1985), groups are more likely to discuss information if it is held by all members (shared information) than if it is held by only one member (unshared information). As groups exchange less information, when they use computer-mediated communication (CMC), it is even more important to mention relevant content using this medium. In studies on face to face communication, informing group members about each others' expertise fostered the exchange of unshared information. In Study 1 this finding was not replicated for groups using CMC. Study 2 shows, that an increased exchange of unshared information is only caused by the knowledge about group members' expertise, when it is interpreted in terms of knowledge and not in terms of competence.
