Hemisphericity style, sex, and performance on a letter-detection task.

Subjects classified by scores on the Preference Questionnaire as preferring either a left- or a right-hemisphericity style were asked to read a one-page passage and to circle each letter t they encountered as they read the passage. There were no statistically significant differences in letter detection between the 58 right- and the 64 left-style scorers. However, contrary to previous findings, the 73 women detected significantly more ts, including unsounded ts, than the 55 men. Our results suggest that hemisphericity style is not an important factor in letter detection.
