Florida Twin Project on Reading Sample
Ongoing cross-sequential study 5,184 MZ (N=1,734) and DZ (N=3,450) twins 50% free or reduced lunch
Procedure In-school state achievement testing 3 x year Parent and child questionnaire mailed home Highlighting the role of behavior and the environment on
reading
Participants 1186 pairs = 413 MZ, 773 DZ Mean age (1st grade) = 6.73 yrs, SD = .47 yrs Taylor et al., 2013
