The aim of this study was to examine whether the effect of semantic richness in visual word recognition (i.e., words with a rich semantic representation are faster to recognize than words with a poorer semantic representation), is changed with aging. Semantic richness was investigated by manipulating the number of features of words (NOF), i.e., the number of characteristics that describe the meaning of words. Half of the words had a high NOF and the other half had a low NOF. Young adults (19.6 years) and older adults (66.3 years) performed a lexical decision task. An interaction was found between age group and NOF on word latencies. More precisely, a facilitatory effect of NOF was observed for the young adults, but not for the older ones. These data are consistent with the assumption of an age-related decline in feedback activation from semantics to orthography.
本研究的目的是检验视觉单词识别中语义丰富性的影响（即语义表征丰富的单词比语义表征较差的单词识别速度更快）是否会随着年龄增长而改变。通过操纵单词的特征数量（NOF）来研究语义丰富性，即描述单词意义的特征数量。一半的单词具有高NOF，另一半具有低NOF。年轻成年人（19.6岁）和年长成年人（66.3岁）进行了词汇判断任务。在单词潜伏期上发现年龄组和NOF之间存在交互作用。更确切地说，观察到NOF对年轻成年人有促进作用，但对年长成年人没有。这些数据与从语义到正字法的反馈激活随年龄下降的假设一致。
