Abstract
The efficient use of knowledge requires semantic control processes to retrieve context-relevant information. So far, it is well-established that semantic knowledge, as measured with vocabulary tests, does not decline with aging. Yet, it is still unclear whether controlled retrieval-the context-driven retrieval of very specific aspects of semantic knowledge-deteriorates in aging, following the same fate as other forms of cognitive control. Here, we tackled this issue by comparing the performance of younger and older native Italian speakers during a semantic feature verification task. To manipulate the control demands, we parametrically varied the semantic salience of the target feature for the cue concept. As compared to their young counterparts, older adults showed worse performance (in terms of reaction times) as the salience of the target feature of the concept decreased. This result suggests that older people have relatively greater difficulties in regulating the activation within semantic representation when conditions pose high demands of controlled retrieval of semantic information.
