Chunking movements into sequence: The visual pre-selection of subsequent goals

▸ In rapid movement sequences visual attention pre-selects subsequent goals. ▸ If sequence production is slow movements are stepwise prepared. ▸ The distribution of visual attention indicates whether movements are chunked or not. ▸ Inter-reach delays of about 400 ms seem to be critical for the chunking of movements. ▸ Without visual landmarks subsequent goals are preselected regardless of sequence speed.
