ABSTRACT
The last several chapters have been based on the assumption that one can detect a member’s interest in the achievement of his group through observing the aspirations he favors for it. Ordinarily, however, in daily living, this degree of interest is estimated on grounds of simpler evidence. It is assumed that a teammate has a tendency to approach work on his group’s task, for example, if he states that it is important to him, that he is willing to work hard on it, and that he is sure his colleagues feel the same as he does; or, it is observed that he actually works hard. One concludes in contrast that a member has a desire to avoid work on his group’s task if he makes derogatory remarks about it, says he is not responsible for the group’s performance, or asserts that he personally is better than the group’s score might suggest.
