PROBLEMThe repression-sensitization (R-S) scale ( l ) was developed to identify two polar types of defensive reaction to threatening stimuli. Individuals who score low on the scale are thought t o utilize repressive or avoidance responses. when presented with conflictful stimuli. Those who score high on the scale, sensitizers, presumably overintellectualize conflicts and maintain a hypervigilance to threat that causes them to experience high levels of anxiety. Since neither of the extreme defensive modes would be expected to result in optimal adjustment, scores on the R-S scale should have a curvilinear relationship with indices of psychological adjustment. While some research supports the curvilinear hypothesis, the majority of the findings strongly suggest a linear relationship between sensitizing defenses and maladjustment (2, 14).The failure to establish empirically a curvilinear relationship between R-S and psychological adjustment may be due to two factors. One difficulty is with the scale itself and has to do with the fact that the R-S scale measures more than defensive style. Recent research by Golin, et al.(8) suggests that the R-S scale measures some combination of "emotionality" and "defensiveness' so that low scores, for example, may reflect either excessive denial and repression of conflict, or a lack of anxiety without significant defensiveness, or some combination of the two.The other difficulty has t o do with the indices of psychological adjustment used t o study the relationship. Several studies have used self-report questionnaires as indicators of maladjustment, and repressors tend to respond to such instruments by denying that anything is wrong with them('. l l ) . Other studies that have approached this question have compared groups of inpatients, outpatients, and normals(14). The failure of such studies to indicate a curvilinear relationship may be due in part to their emphasis on broad indicators of psychopathology rather than on indices of psychological health.The present study approached the issue of linearity-curvilinearity by focusing on an aspect of psychological health related to Rogers'(13) concept of openness to experience. Psychological health may be viewed in terms of how the individual deals with affective experience. Is he open to and able to integrate his emotional experiences with the situational context and his ensuing behavior? Or does he become constricted, on the one hand, or disorganized, on the other hand, in relation to his affects? Assessment of Ss' characteristic ways of dealing with affective experience should elucidate the two defensive modes purportedly measured by the R-S scale. While the R-S scale does not focus specifically on defensiveness against affects, if in fact it does measure the two polar defensive modes, then both types of extreme scorers should perform less well on a task that requires affective expression than would neutrals.A study by Lefcourt(ll) found a linear relationship between R-S and "affectideation," with sensitizers more "emotional" than r...
