Experiments investigated the impact of message elaboration on attitude change-message recall correspondence when attitude change occurs in an on-line (as attitude-relevant information is received), or memory-based (on the basis of retrieved attitude-relevant information) fashion. In 2 experiments, Ss' processing goals were manipulated to increase or inhibit on-line change and message elaboration. As predicted, Ss reported postexposure attitudes more rapidly in on-line vs memory-based conditions. Decreased message elaboration increased attitude-recall correspondence, regardless of when attitude change occurred. Increased elaboration produced elaboration-attitude judgment correspondence. Results suggest that recall of message content will best predict persuasion when message content is encoded free of elaborations, regardless of when attitude change occurs.
实验研究了在态度改变以在线方式（即当接收到与态度相关的信息时）或基于记忆的方式（基于检索到的与态度相关的信息）发生时，信息详尽程度对态度改变与信息回忆一致性的影响。在两个实验中，操纵了被试的加工目标以增加或抑制在线改变和信息详尽程度。正如所预测的，与基于记忆的条件相比，被试在在线条件下更快地报告了接触后的态度。信息详尽程度的降低增加了态度与回忆的一致性，无论态度改变何时发生。详尽程度的增加产生了详尽程度与态度判断的一致性。结果表明，当信息内容在没有详尽阐述的情况下被编码时，无论态度改变何时发生，信息内容的回忆将最能预测说服力。
