Previous research suggests that in addition to being a characteristic of @entity161 , @entity409 also predates the onset of the syndrome. The research reported here was intended to examine further the neuromotor development of @entity1 with preschizophrenia traits. This study is part of a larger "archival-observational" project that uses childhood home movies to explore the developmental precursors of @entity161 . Group comparisons revealed a higher rate of @entity854 in the preschizophrenia @entity1 when compared to their healthy siblings, preaffective disorder subjects, the healthy siblings of @entity1 with @entity1316 , and subjects from families with no @entity1032 . The preschizophrenia subjects also showed poorer motor skills when compared to their healthy siblings and preaffective disorder subjects. When diagnostic group comparisons were made within age spans, the group differences were significant only in the first 2 years of life. Post hoc analyses also revealed that the preschizophrenia subjects' @entity854 occurred primarily on the left side of the body. The abnormalities included @entity717 and posturing of the upper limbs, similar to the motor signs described in earlier reports on diagnosed @entity161 @entity1 . The findings are discussed in light of their implications for the developmental origins of @entity161 . Limitations of the study, including problems with sample representativeness and the reliance on observational data, are also discussed.
