This paper estimates the relationship between handedness and social adjustment. In addition to binary measures of hand preference, we also use a continuous measure of hand skill. Outcomes at ages 7, 11 and 16 are studied. Using a semi-parametric estimator it is shown that non-righthandedness (as hand-preference) is associated with poorer social adjustment but this effect disappears as the individuals age. The continuous measure of hand skill has a non-monotonic effect on social adjustment with poorer social adjustment at the extreme values of the continuum. Poorer social adjustment in childhood has been shown to predict poorer socio-economic outcomes later in life.
