The present investigation examines the effects of manifest anxiety, prior success-failure experience, and task set on judgmental confidence and extremity. In a sample of 141 male college students, a significant triple interaction was obtained for both confidence and extremity, indicating that success-failure and task sets have a differential impact upon these judgmental variables for subjects low and high in manifest anxiety. The findings provided evidence for the operation of two processes in judgmental behavior, conceptualized as desire-for-certainty and cognitive risk taking. Our conclusions emphasized the multiple determination of judgmental phenomena by personality and situational influences.
