Using a serial memory task, human performance and biorhythms were studied in the laboratory for a fifteen week period. The purpose of the experiment was to determine whether dependency between performance and biorhythmic cycles existed for the subjects observed. Analysis of the data using the Chi-Square Contingency Test collected from 4 subjects showed a significant dependency at the .05 level existed between 2 of 3 biorhythmic cycles and human performance as well as near significant dependency existing for the third cycle and human performance. Further analysis using the x(2) one sample test showed no significance between critical days and categories of performance at the ,05 level.
