Temporal Chunk Signal Reflecting Five Hierarchical Levels in Writing Sentences


Previous research on the temporal chunk signal has focused on the use of pauses in behaviour to probe chunk structures in working memory. On the basis of some of these studies, a hierarchical process model has been proposed, which consist of four hierarchical levels describing different kind of pauses. In this model, the lowest level consists of pauses between strokes within letters. On higher levels, there are pauses between letters, words, and phrases. Each level is associated with a larger amount of processing when retrieving these chunks from memory. The main aim of the present study is to test whether the temporal chunk signal can distinguish a fifth level, the sentence level. A secondary goal is to replicate the findings which were used to construct the hierarchical process model in a manner that overcomes some of the limitations of the earlier experiments.
