The objectives of the study are to estimate the prevalence of left-hand dominance among children of selected mothers in an urban city and to determine the mothers' stereotypes about left-handedness. A cross-sectional study of mothers (N = 222) selected by systematic random sampling was done. The mothers were interviewed with structured questionnaires. Data were analyzed with appropriate descriptive statistics on SPSS. The estimated prevalence of left-hand dominance in their children was 7.52%. A left-handed mother was more likely to have a left-handed child. A substantial number of the mothers held negative stereotypes about left-hand dominance and showed a good knowledge about other types of handedness with a significant difference in the responses between right-handers and left-handers. The prevalence of left-hand dominance in their children supports previous reports which show that left-handedness usually occurs in less than 10% of the population. The mothers' negative stereotypes signify the likelihood of stigmatizing the children with this hand dominance.

Unlabelled: Early skill learning develops in the context of activity changes in distributed cortico-subcortical regions. Here, we investigated network hubs-centers of information integration and transmission-within the brain network supporting early skill learning. We recorded magnetoencephalographic (MEG) brain activity in healthy human subjects who learned a moderately difficult sequence skill with their non-dominant left hand.
