Packet type sequence position encoding: The new interpretation of the long term effects of chinese words

In this study, we have used Chinese words as the experimental material to investigate the word length effect of short-term memory using the sequence position reconstruction method. It was found that the recall performance of short words was significantly better than that of long words in the pure word list, showing the word length effect. In the mixed word list, there was a significant benefit in the recall performance of long words in Experiment 1 and Experiment 3, and a noticeable benefit was also shown among short words in Experiment 3. The results suggest that at the item level, processing is based on phonological complexity, which accounts for the presence of word length effects in the pure word list. At the sequence position processing level, the pure word list was dominated by temporal position coding, while the mixed word list was dominated by grouped coding and temporal position coding. Meanwhile, both long and short words in a mixed word list benefit due to the involvement of grouped coding, and grouped sequence position coding displays the features of syntactic encoding.The results suggest the temporal distance between the consecutive lexical coding plays an important role at the later retrieval stage.
