This study is the last in a series of explorations, conducted during the period from 1969 through 1972, into the applicability of group training to theatre at the University of Utah. The experimental group, which consisted of the 1971 and 1972 University of Utah Shakespeare Players, were compared to two control groups. Two personality measures were used to examine personality changes, and a special rating form was used by audiences, directors and casts, and trained raters to evaluate individual and cast performances in the three groups. Findings suggest that group work aided the experimental group in achieving true ensemble performance, that (as measured by the personality tests) the casts corresponded to their directors, and that individuals with "more functional" conceptual systems were rated more highly as actors than were those with "less functional" systems. Qualitative observations were also used to interpret the effects of formal group training under the direction of a trained group leader. (Author/AA)
