Demographic and Visuomotor Skills Survey Results. Notes: Demographics. Subjects self-reported age, education, and gender. A chi-square test was performed to test whether the ethnicity distribution of the subjects with the Val/Met genotype differed from the distribution expected based on that of the subjects with the Val/Val genotype. General Survey. Subjects were asked a series of questions on a 5-point Likert scale. Skills Survey. Subjects were asked “At what level do you” do each of the categories on 4-point Likert scale of self-ranked skill, coded such that 1 = “Rarely”, 2 = “Recreationally”, 3 = “Competitively”, and 4 = “Professionally”. Hours Spent Per Week. Subjects were asked how many hours per week they spend doing each of the activities covered in the categories. Subjects were also asked to state specifically which sports, games, instruments, etc. that they played (not reported here). A one-way analysis of variance (ANOVA) was performed to assess whether subjects with each genotype were matched on all factors except ethnicity (reported in Table 2).
