BMC Neuroscience

Table 3 Heritability estimates for three attentional networks and mean RT

Heritability measure	Alerting	Orienting	Conflict	RT
h²_F = 2 (r_MZ - r_DZ)	.18 (-.73, 1.10)	-.59 (-1.56, .41)	.89 (.09, 1.70)	.16(-.42, .75)
h²_H = (r _MZ - r_DZ)/ (1 - r _DZ)	.14	-.49	.62	.24
ML fit:
H	.43 (-.85, .85)	.00 (-.69, .69)	.85 (.29, .93)	.40(-.90, .90)
h²	.18	.00	.72	.16
c	.53 (-.79, .79)	.50 (-.70, .70)	.00 (-.72, .72)	.76(-.90, .90)
c²	.28	.25	.00	.58
e	.73 (.53, .91)	.86 (.70, 1.00)	-.53 (-.73, -.38)	-.51(-1.00,-.36)
e²	.53	.74	.28	.26

Note: Confidence intervals of h²_F were estimated based on Appendix 6 (reference[54];) h²_H was cited in (reference[55];) ML, Maximum Likelihood fit, (reference[56];) h: path coefficient for additive genetic; c: path coefficient for shared environment; and e: path coefficient for specific environment.
