Retrieval of attribute information as a function of processing depth

The effects of processing depth on retrieval of attribute information was investigated using a modified probe-recognition procedure. Subjects decided whether a probe word was a synonym, a homonym, identical to, or not related to any word of a previously presented three-word set. Depth of processing was manipulated by priming with a dimensional cue prior to the presentation of the study set. The dimensional cue specified the relation in question between probes and potential target words in each study set. Effects were assessed relative to unprimed conditions where subjects had the dimensional relation specified during probe presentation. The probe word followed the three-word set by a 0-, 10-, or 30-sec filled or unfilled delay. Priming effects were reflected in reaction time but not recognition accuracy, with degree of effect related to level of processing. Synonyms were affected most, homonyms next, identity least.
