Recent studies of vocational structure have demonstrated that experimentally provided vocational constructs are used in less complex, less differentiated ways than are subjects' personally elicited construct dimensions. The possible reasons underlying these differences are addressed in this 2part study. Results of Study 1 supported significant differences between the use of elicited and provided constructs and ruled out one methodological artifact that may have accounted for these differences. Study 2 helped to isolate the personal meaningfulness of the elicited construct as an active agent that accounts for differences in the use of these vocational constructs. Findings of both studies document, for the first time, a means of increasing differentiation and converge to suggest the important role of personal meaning in vocational structure.
