Abstract: | The relationship between the phonological properties of speech sounds and the corresponding semantic entries was studied in two experiments using response time measures. Monosyllabic words and nonsense words were used in both experiments. In Experiment I. Ss were each presented with individual items and were required, in three different conditions, to respond positively if (1) the item contained a particular final consonant, (2) the item was a real word, (3) the item contained either a particular consonant or was a real word. Latencies indicated that separate retrieval of phonological and lexical information took about the same time. but that their combined retrieval was longer, indicating a serial or overlapping process. In Experiment II, Ss were presented with pairs of items, and they responded positively if (1) the two items were physically identical, (2) the two items were lexically identical (both real words or both nonsense words). Response latencies were longer for lexical than for physical matches. Lexical matches were’ significantly slower than physical matches even on the same pair of items. The results imply differential accessibility to separate loci of phonological and semantic features. |
