This study investigated the influence of enhanced textual redundancy on affective interpretations made by unilaterally right or left hemisphere brain-damaged adults and normally aging control subjects. Emotional interferences were drawn from linguistic or prosodic material, and redundancy effects were examined within and across stimulus boundaries. Results indicate that heightened semantic redundancy improved the accuracy of linguistic and prosodic judgements of affect for all groups. Correct prosodic judgements were also made more quickly by a subset of each group when textual redundancy was maximized. The facilitory influence of increased redundancy was not attributable solely to perseveration or response rigidity. Possible mechanisms by which semantic redundancy affects cognitive processing are considered.
本研究调查了增强文本冗余对单侧右脑或左脑损伤的成年人以及正常衰老的对照受试者所做情感解释的影响。情感干扰取自语言或韵律材料，并在刺激边界内和跨刺激边界检查冗余效应。结果表明，语义冗余的增加提高了所有组对情感的语言和韵律判断的准确性。当文本冗余最大化时，每组中的一部分人做出正确韵律判断的速度也更快。冗余增加的促进作用并非仅归因于持续性或反应僵化。文中还考虑了语义冗余影响认知加工的可能机制。
