Hécaen & Sauguet (1970) reported that, according to a handedness inventory measure, familial sinistrality among left‐handers (brain‐damaged patients) was associated with weak left‐handedness. We assessed the relationship of familial sinistrality and degree of left‐handedness among 71 normal left‐and 80 right‐handed subjects. No general relationship of degree of left‐handedness, defined by four handedness tasks, to familial sinistrality obtained. Only one of the tasks (finger tapping speed) significantly differed between familial and non‐familial left‐handers, the familial left‐handers being more strongly left‐handed on the task.
