SUMMARY
–Judges selected on the basis of high scores in need for achievement performed better than low scorers in flavor difference detection tests repeated 7 times in a 4‐wk period. Each test consisted of triangular, paired and degree of difference discriminations in 6 comparisons of varying difficulty devised from cakes made with fresh, dried and irradiated eggs. During the last 5 tests, high achievers showed significantly superior odd sample selection. Throughout the test period high achievers showed somewhat better discrimination of moderately difficult comparisons and a higher incidence of total responses. Degree of flavor difference expressed showed dependence on personality scores for aggression, nurturance, autonomy, harmavoidance and impulsivity.
