Is a maturational lag associated with left-handedness? A research note
Article Abstract:
Left-handedness is unrelated to delayed physical maturation; determined using the current height, relative height and predicted adult height in three large-scale samples of prepubertal children. Left-handedness has little effect on physical maturation during the prepubertal development stage. This finding is contradictory to the left-handed developmental lag hypothesis which says that birth-related stressors slow down normal development in nonclinical left-handed children.

Sibling sex ratio of boys with gender identity disorder
Article Abstract:
Probands of 444 boys, who were either referred for assessment or were subjects of case studies on gender identity disorder, represented a sibling sex ratio of 131.1:100 (brothers:sisters). This ratio replicated the Blanchard, Zucker, Bradley and Hume findings (1995) of 140.6:100 which suggested that gender identity disorder in boys was due to excess of brothers. To test these findings, related psychosocial and biological studies are recommended.

Handedness in boys with gender identity disorder
Article Abstract:
Research on sex differences examines the relationship between left-handedness and gender identity disorder in boys. Findings suggest that left-handedness is a behavioral indication of a deeper neurobiological process related to gender identity disorder in males.
