Past research showed that considering a persuasive message in light of important rather than unimportant values creates attitudes that resist later attack. The traditional explanation is that the attitudes come to express the value or that a cognitive link between the value and attitude enhances resistance. However, the current research showed that another explanation is plausible. Similar to other sources of involvement, considering important rather than unimportant values increases processing of the message considered in light of those values. This occurs when the values are identified as normatively high or low in importance and when the perceived importance differs across participants for the same values. The increase in processing creates resistance to later attacks, and unlike past research, individual-level measures of initial amount of processing mediate value importance effects on later resistance to change. Important values motivate processing because they increase personal involvement with the issue, rather than creating attitudes that represent or express core values.
过去的研究表明，根据重要而非不重要的价值观来考虑有说服力的信息会产生能抵抗后续攻击的态度。传统的解释是，这些态度开始表达价值观，或者价值观与态度之间的认知联系增强了抵抗力。然而，当前的研究表明另一种解释是合理的。与其他参与来源类似，根据重要而非不重要的价值观来考虑会增加根据这些价值观所考虑信息的处理。当价值观在重要性上被认定为规范上的高或低，以及当相同价值观在不同参与者之间的感知重要性不同时，就会发生这种情况。处理的增加会产生对后续攻击的抵抗力，与过去的研究不同，初始处理量的个体层面测量介导了价值重要性对后续抗变化能力的影响。重要价值观激发处理，是因为它们增加了个人对该问题的参与度，而不是创造代表或表达核心价值观的态度。
