Abstract
The degree to which item and associative information can be distinguished at retrieval was assessed using a frequency-judgment task. Words were shown various numbers of times individually and as members of word pairs. At test, subjects judged the frequency of the word pairs and a word’s frequency as an individual item, its frequency as a member of word pairs, or the combined frequency of the word. Subjects made all of these judgments with considerable accuracy. The frequency of presentations in the nontarget format had consistent, but small, effects on the judgments for the target frequencies. The results provide further support for the distinction between item and associative information and for the source-monitoring framework of Johnson, Hashtroudi, and Lindsay (1993), and they have important implications for global matching models of memory.
