  • Title: The origin of left hand preference: pathological and non-pathological influences.
    Author: Liederman J, Coryell J.
    Journal: Neuropsychologia; 1982; 20(6):721-5. PubMed ID: 7162597.
    Abstract:
    Models of the origin of left hand preference were tested with prospective data. Infants with and without a history of perinatal complications, matched for age, sex and parental handedness, were filmed at 6 weeks of age. Children with a history of perinatal complications lacked the rightward headturning bias of those children without a history of perinatal trauma. Children with a history of perinatal complications were also deviant with reference to the duration of a postural reflex and its degree of lateralization. Perinatal complications may delay the establishment of volitional hand use as well as increase the probability of left-handedness. The data were interpreted as supporting SATZ's (Cortex 8, 121-135, 1972) rather than BAKAN et al.'s (Neuropsychologia 11, 363-366, 1973) model of "pathological" left-handedness.
