Research has investigated how each of numerous indicators of attitude strength separately affect an attitude's stability, resistance to persuasion, and utility in predicting behavior. More recent studies, however, have revealed interactive effects of attitude certainty and objective ambivalence. High (vs. low) certainty strengthened an attitude low in objective ambivalence (e.g., higher resistance to persuasion and attitude stability) but weakened an attitude high in objective ambivalence (e.g., lower resistance and stability). Extending these findings, we show that attitude certainty also moderates the effect of an attitude high or low in subjective ambivalence on attitude stability. Moreover, we generalize an interaction perspective on indicators of attitude strength by showing that attitude knowledge also interacts with ambivalence and certainty regarding attitude stability. Findings are discussed in regard to the interplay of different strength indicators more generally.

主观态度矛盾、知识和确定性对态度稳定性的交互作用：以驾驶电动汽车为例

研究调查了态度强度的众多指标中的每一个如何分别影响态度的稳定性、抗说服力和预测行为的效用。然而，最近的研究揭示了态度确定性和客观矛盾心理的相互作用。高（相对于低）确定性增强了客观矛盾心理低的态度（例如，对说服和态度稳定性的抵抗力较高），但削弱了客观矛盾心理高的态度（例如，较低的抵抗力和稳定性）。扩展这些发现，我们表明态度确定性也会调节主观矛盾情绪高或低对态度稳定性的影响。而且，我们通过表明态度知识也与态度稳定性的矛盾性和确定性相互作用，概括了态度强度指标的交互观点。更普遍地讨论了关于不同强度指标的相互作用的结果。
