Our objective was to study cultural (first language) and innate (handedness) influences on the performance (omissions, site of beginning) of the cancellation test. We studied 71 healthy subjects aged between 18 and 52 years. There were 41 right-handed and 14 left-handed with Spanish as first language in Buenos Aires study site, and 16 right-handed with Hebrew as first language in Israel study site, matched by age and education. We used the Mesulam verbal and non verbal cancellation test, and a modified verbal version in hebrew letters. Omissions in the right side were more frequent in right-handed Spanish-speaking subjects (p < 0.001). We did not find this asymmetry in the individuals from Israel. While all right-handed Spanish-speaking subjects began the test by the left upper corner, most of the left-handed did it by the right upper corner. We conclude that asymmetry in the performance of the cancellation test may have genetic and/or cultural influences.
