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 simple reaction time for the “Detection” task, the ‘Some’ coefficient is -0.010. This indicates the adjusted mean is lower in the ‘Some’ group than the ‘None’ group
