The present study of right hemisphere stroke patients showed
that presence of visuospatial neglect in conventional neglect
tests at the postacute stage was strongly associated with an
aberrant search pattern in a verbally reported visuo-perceptual
scanning test. Compared with normal controls, patients with
visuospatial neglect showed a greater proportion of repeated
readings of the same target, shorter search sequences, more
shifts between horizontal, vertical, and diagonal search, and
lower proportion of horizontal search. The relation between
spatial neglect and a deficient search pattern was strongly
influenced by the asymmetric allocation of attention in the
scanning test, with the exception for the proportion of repeated
reading which was not influenced by this asymmetry. At follow-up,
a significant recovery was noted in the neglect group for the
proportion of repeated readings and for the asymmetry in the
allocation of attention. However, a high number of omitted targets
in the search test was still a common finding in the neglect
group and it was suggested that a non-lateralized attentional
deficit may have played an important role behind the ineffective
search at this point of time. (JINS, 2002, 8,
