Table 2.
Expected numbers of right- and left-handed individuals with left and right cerebral dominance for language in a hypothetical population of 100, according to McManus's model of handednessa.
| language-dominant hemisphere | ||
|---|---|---|
| left | right | |
| right-handers | 83 | 7 |
| left-handers | 7 | 3 |

The numbers are based on p(D)=0.8. DD individuals are assumed to be right-handed and left-cerebrally dominant for language. In DC individuals, the proportions of right-handed and left-cerebrally dominant individuals are both 0.75, and are assumed to be uncorrelated. CC individuals are assumed to be equally divided among all combinations of right- and left-handedness and left and right cerebral dominance.
