The genetic and environmental correlations between measures of bottom-up and top-down systems.

	Correlation Between Factors:
	rG	rE
Sensation Seeking & Lack of Planning Factors ^a
Females	0.01 (−0.2 7, 0.29)	0.28 (0.2 0, 0.35)
Males	0.62 (0.29, 0.94)	0.04 (−0.07, 0.15)
ZSS Total & MPQ Control Scales
Females	0.44 (0.1 3, 0.75)	0.44 (0.3 7, 0.52)
Males	0.79 (0.27, 1.00^b)	0.30 (0.18, 0.41)

Notes: MPQ=Multidimensional Personality Questionnaire (Tellegen, 1982); ZSS=Zuckerman Sensation Seeking Scale (Zuckerman, 1964). Estimates are from full ACE models. The shared environmental correlations (rC) were either 0 or not estimable, primarily due to shared environmental influences accounting for a non-significant proportion of variance for all measures of bottom-up and top-down systems.

The Lack of planning factor and sensation seeking factor were both derived from factor analyses conducted in the current study.

Estimated bounded at 1.0.
