Visual neglect is routinely tested using cancellation tasks. On these
tests, subjects without visual neglect are expected to use a systemati
c left to right search pattern and detect virtually all targets (Weint
raub & Mesulam, 1985). This premise of normal scanning being systemati
c and lep to right also provides the foundation for scanning retrainin
g, one rehabilitation approach for neglect. However, in an increasingl
y multicultural society, it behooves us to investigate cultural variat
ions in normal visual scanning patterns. The purpose of this study was
to begin to investigate normal visual scanning patterns in a sample o
f unilingual, Mandarin-speaking adults. The study was conducted at the
Anhui Medical University, Hefei, China. Twenty-nine subjects complete
d three cancellation tasks: the Bells Test (Gauthier, Dehaut, & Joanet
te, 1989) and two from the Cancellation Test (Weintraub & Mesulam, 198
5). The results showed that fewer subjects than reported by Gauthier e
t al. (1989) started their search with a left top or left middle orien
tation and fewer used a systematic scanning pattern. Clinicians respon
sible for testing and treating visual neglect in multicultural populat
ions should be aware that more variation may be seen in performance on
routine scanning tasks.
