Denial of separation anxiety as measured by a serial tachistoscopic technique.

A mother-child separation stimulus was repeatedly presented by standard Defense Mechanism Test procedure, at increasing durations of tachistoscopic exposure to 60 clinical and nonclinical subjects. Subjective verbal reports were coded blindly for evidence of perceptual distortions presumably indicative of denial of separation anxiety. Low scores on two items measuring sensitivity to separation anxiety and intolerance of aloneness were, as predicted, significantly more often characterized by codings of denial on the tachistoscopic exposures than subjects with high sensitivity to separation anxiety. Stability of effect became stronger when only very low and very high scores were compared for perceptual denial on the last four presentations of the series. This technique, employing other types of anxiety-evoking stimuli, may represent a reliable instrument to reveal the presence of defences toward each of the most relevant conflictual areas of the personality.
