8/7 Our future work aims to uncover the neural mechanisms underlying these rapid, coarticulated reaching sequences in NHPs performing the same task. Stay tuned!

7/7 Our findings indicate that preparing multiple reaches to spatial targets does not impose additional temporal costs relative to preparing a single reach. It remains to be tested how generalizable these results are to other effectors, such as finger-press sequences.

6/7 In fact, when first-target ambiguity is eliminated by ordering the sequence spatially, we found that RT is constant across the number of displayed targets, even though participants are still preparing a sequence.

5/7 We report that RT increases with additional sequence elements presented. However, this RT increase is fully explained by the first-target ambiguity and that sequence preparation causes no RT cost.

4/7 Without using RT as a measure of sequence preparation, we first showed that first movement kinematics are systematically shaped by future movement goals and that this influence emerges immediately at the onset of the first movement, indicating that sequence preparation has happened during RT.

3/7 We independently manipulated the number of future targets displayed, the number of targets to be acquired, and the spatial arrangement of the targets. This allowed us to vary the demands of sequence preparation and first-target ambiguity, enabling a direct assessment of their influence on RT.

2/7 Here, using a sequential reaching paradigm, we tested whether the RT increases with longer sequences are actually driven by sequence preparation, or whether they are, to some extent, caused by participants facing greater ambiguity in selecting their first movement in the longer sequence.

1/7 A core behavioral finding from earlier behavioral studies is that reaction time (RT) increases when participants are presented with longer sequences, and this indicates that individuals prepare multiple movements prior to initiating the first movement in the sequence.
