Experiment 1 assessed the relative contribution of phonemic and semantic dimensions of memory via a yes-no recognition test for homonyms, synonyms, and intact words. A word was presented as part of a sentence or as part of a scrambled list of words. One of three recognition tests was administered at retention intervals of 5 or 20 seconds. Results relate sentence context to decline of synonym recognition as a function of retention interval. Experiment 2 varied the imagery of a sentence noun. Two imagery-comprehension models state that either all sentence words are stored in one image or individual words serve as memory anchors. These alternative possibilities, as well as the effects of imagery on phonemic and semantic memory, were examined over retention intervals of 4, 12, and 36 seconds.
