aThese are regression coefficients adjusted for age, gender, language other than English, handedness, and socioeconomic status. The coefficient represents the difference in adjusted means of the outcome between each of the exposure groups ‘Some’ and ‘More’ and the non-exposed reference group ‘None’. For example, for the accuracy in the “Detection” task, the ‘Some’ coefficient is 0.007and the ‘More’ coefficient -0.004. This indicates the adjusted mean is higher in the ‘Some’ group but lower in ‘More’ group when compared to the ‘None’ group
