title: Physical features vs meaning: A difference in decay.
abstract: The encoding of either physical or semantic features of words was biased in an intentional learning situation. A modified recognition test was then employed to assess the effectiveness of this study manipulation and its consequences for retention. The Ss were required to select test items that were either physically similar, semantically similar, or identical to a study word. Results revealed that Ss biased toward physical encoding were more successful in selecting physically similar than semantically similar test items, while the opposite was true of Ss biased toward semantic encoding. The Ss in the two study conditions did not differ in their ability to select test items that were identical to a study word. This pattern of results was interpreted as evidence that semantic and physical information can be equally well retained over the long term. Limits on the generality of prior findings of rapid decay for physical information are discussed.
