Abstract
Phonological and semantic representation for pictures and words: order of access or memory system? This paper explored the possible dissociation between memory systems for pictures and words and the order of access of these stimuli to different types of information. Semantic and phonological priming with different combinations of pictures and words was used. Results of the experiments showed that priming depended on the time of exposure to the prime. When the prime were presented for 1000 ms., the presence of priming effects depended on the type of task, on the modality of the target and on strategic factors. With long exposures, priming did not varied within or across modalities. In contrast, when the prime was presented for 32 ms. modality shifts were important, indicating that visual analyses were taking place at this time. When the prime was presented for 50 ms. semantic priming appears but only when the prime was a picture.
