| Outline of Final Research Achievements |
It is well established that long-term phonological knowledge contributes to short-term retention of verbal sequences. The present project examined how temporal factors influence usage of long-term phonotactic knowledge. First, we compared recall performance for two types of nonword lists, consisting of a mixture of high- and low- frequency bi-morae sharing the same bi-mora frequency. In one type of list, temporal gaps were inserted at low-frequency bi-mora positions. In another type, temporal gaps were inserted at high-frequency bi-mora positions where we expected a disconnection of the two morae, which otherwise possessed a strong association. The latter manipulation reduced the effect of bi-mora frequency on recall performance. Second, experiments manipulated position-specific and position-free bi-mora frequency. The results indicated the presence of two types of long-term phonotactic knowledge implementation, one being more and the other being less sensitive to temporal structure.
