[EN]The aim of this study is to investigate whether
the fingers are represented separately from the palm. An
exogenous spatial orientation paradigm was used where
participants had to detect a tactile stimulus that could
appear on the palm, the middle finger or the ring finger of
the left hand. The tactile target was preceded by a non predictive cue using different stimulus-onset asynchronies
(SOA). We observed a Facilitation Effect in the palm and
Inhibition of Return (IOR) for fingers using a short cue target SOA, whereas the IOR was found in fingers and
palm in long cue-target SOA. Also we observed a ‘Cue
above Target’ effect (facilitation effect when the Cue had
appeared distal to the target location in a vertical line) at
the long SOA. Together, we suggest that the general pat tern of results supports the proposed hypothesis about the
different mental representation of fingers and palms, but
with a considerable and hierarchical interrelation between
them.
