People look at emptied spatial locations where information has
been presented during encoding. There is evidence that this socalled
‘looking at nothing’ behaviour plays a functional role in
memory retrieval of visuospatial and verbal information. However,
it is unclear whether this effect is caused by the oculomotor
movement of the eyes per se or if covertly shifting attention
is sufficient to cause the observed differences in retrieval
performance. In an experimental study (N = 26), participants
were manipulated in being able to shift either their eyes or their
focus of attention to a blank spatial location whilst retrieving
verbal information that was associated with the location during
a preceding encoding phase. Results indicate that it is not
the oculomotor movement of the eyes that causes the facilitation
while retrieving verbal materials, but rather covert shifts
of attention are sufficient to promote differences in retrieval
performance.
