Rorschach white space responses bear, from Rorschach's Psychodiagnostics up to Exner's Comprehensive System, the meanings of some sort of oppositional trend, negativistic tendencies, contrariness accentuating uniqueness, display and defence of autonomy and self-determination, striving for independence, self-assertiveness, and mastery (Exner, 1993; Weiner, 1998). Yet, attempts to relate white space responses empirically to pertinent non-Rorschach variables -in order to sustain and confirm the aforementioned interpretative meanings -yielded in the long run only equivocal results.Most of the empirical research data linking Rorschach space responses to the broad generic term of oppositionalism were reviewed by Fonda (1977), and almost no additional data have been provided in a more recent review of the issue (Frank, 1993). The volume of pertinent empirical research is surprisingly meager, and falls basically into two classes of investigations, one in which Rorschach space responses serve as an independent variable and non-Rorschach variables serve as dependent variables; and another class of investigations in which Rorschach space responses serve as dependent variable and non-Rorschach variables as independent variables. The overall impression regarding the results provided by both classes of investigation is that evidence associating space responses with oppositionalism is weak and inconsistent, and that probably this unfortunate state of affairs may be attributed to the vague and sometimes problematic ways of operationalizing oppositionalism (Fonda, 1977; Frank 1993).The data reported here are not an outcome of a planned investigation, but rather an incidental result of having the opportunity to compile data gathered from the same subjects in two distinct unrelated studies, one an already published Rorschach investigation (Last & Weiss, 1976) and
