When do we think we move when we make a voluntary action? Previous studies
have pointed to an anticipatory awareness of action (i.e. we think we move
before we actually do), but have not investigated the content or locus of m
otor awareness. In the experiment reported here the authors localize the ti
me of awareness of the first movement in a sequence within the context of a
specific information-processing model. The results suggest that our awaren
ess of our own actions is associated with some pre-motor event after the in
itial intention and preparation of action, but before the assembly and desp
atch of the actual motor command to the muscles.
