An individual's decision-making process is defined as sets of temporally sequential subprocesses by which he receives, evaluates, and acts on information under conditions of uncertainty. The stages of this process are initial choice, analysis and synthesis. A modified version of Form E of the Dogmatism Scale and an original Political Issue Experiment were administered to 1,051 male and female students in grades nine through twelve of six public high schools in five Michigan communities. The Two Person Game experiment developed by Dawson was also used. Three hypotheses were tested: (1) both open and closed minded persons without information will choose in accordance with authorities, (2) closed minded people using authority's information complete the analysis stage at a later point than open minded people, (3) closed minded people, using authority's information, complete the synthesis stage at a later point than open minded people. Hypothesis Two and Three were not supported by data. (Author/KJ)
