Handedness, Health and Cognitive Development: Evidence from Children in the National Longitudinal Survey of Youth Journal of the Royal Statistical Society: Series A (Statistics in Society) 176,4 (October 2013): 841-860.

Using data from the child supplement of the US National Longitudinal Survey of Youth, and fitting three-level random-effects models of child health and cognitive development, we test whether left-handed children have different outcomes from those of their right-handed counterparts. The health measures cover both physical health and mental health, and the cognitive development test scores span vocabulary, mathematics, reading and comprehension. Overall we find little evidence to suggest that left-handed children have a significantly higher probability of experiencing injury, illness or behavioural problems. In contrast, we find that left-handed children have significantly lower cognitive development test scores than right-handed children for all areas of development with the exception of reading. Moreover, we find no strong evidence that the left-handedness effect differs by gender or age. |

Handedness, Health and Cognitive Development: Evidence from Children in the NLSY IZA Discussion Paper No. 4774, Bonn, Germany: Institute for the Study of Labor, February 2010 Cohort(s): Children of the NLSY79 Publisher: Institute for the Study of Labor (IZA) Keyword(s): Accidents; Child Health; Cognitive Development; Digit Span (also see Memory for Digit Span - WISC); Handedness; Injuries; Modeling, Fixed Effects; Peabody Individual Achievement Test (PIAT- Math); Peabody Individual Achievement Test (PIAT- Reading) Permission to reprint the abstract has not been received from the publisher. Using data from the US National Longitudinal Survey of Youth, and fitting family fixed-effects models of child health and cognitive development, we test if left-handed children do significantly worse than their right-handed counterparts. The health measures cover both physical and mental health, and the cognitive development test scores span (1) Memory, (2) Vocabulary, (3) Mathematics, (4) Reading and (5) Comprehension. We find that while lefthanded children have a significantly higher probability of suffering an injury needing medical attention, there is no difference in their experience of illness or poor mental health. We also find that left-handed children have significantly lower cognitive development test scores than right-handed children for all areas of development with the exception of reading. Moreover, the left-handedness disadvantage is larger for boys than girls, and remains roughly constant as children grow older for most outcomes. We also find that the probability of a child being left-handed is not related to the socioeconomic characteristics of the family, such as income or maternal education. All these results tend to support a difference in brain functioning or neurological explanation for handedness differentials rather than one based on left-handed children living in a right-handed world. |
