	AX Errors	BX Errors
Phenotypic Correlations
BX Errors	.28 (.21, .34)
AY Errors	.11 (.05, .18)	.06 (−.02, .13)

Genetic Correlations
BX Errors	.95 (.60, 1.00)
AY Errors	.40 (.09, .78)	.32 (−.11, .65)

Unique Environmental Correlations
BX Errors	.03 (−.08, .15)
AY Errors	.01 (−.11, .13)	−.04 (−.16, .12)
