Flicker Fusion Frequency as a Function of Anxiety Reaction; An Exploratory Study

HERBERT E. KRUGMAN 1

1 Columbia University

Flicker fusion frequency has previously been found to differentiate between normals and cases exhibiting various types of abnormal metabolicrate states. This experiment attempted, in an exploratory way, to study the relationship between FFF and an anxiety reaction state found rather frequently among Army personnel shortly after their return from Air Forces combat assignments overseas.

Fifty such cases (termed "operational fatigue" in the AAF) and 50 normal aircrew returnees were selected for testing under standardized conditions. Statistically significant differences were found between the mean FFF scores of the two groups although the distribution of scores overlapped considerably.

Because of the relationship between FFF and anxiety reaction ("operational fatigue") demonstrated in this study, it would be expected that the FFF scores of such patients would rise during the progress of successful therapy. Further research would seem to be indicated.

Note:
This study was carried out as part of the Army Air Forces Aviation Psychology Program.
