title: Season of birth and handedness in young adults.
abstract: This study explored the relationship between season of birth and handedness, taking into account gender and nationality variables. Young adults from three countries (2120 females and 1353 males; 877 Spanish, 2184 Italian, and 412 French), aged from 18 to 30 years, filled the Edinburgh Handedness Inventory (EHI). According to the literature, the percentage of left-handed participants in the whole sample was 9.30%. The distribution of left- and right-handed participants was not significantly different among the seasons of birth. The present data do not support a significant season of birth effect on handedness in young adults.
