Table 2.

Phenotypic correlations for respiratory sinus arrhythmia (RSA), heart rate (HR1 at rest 1, HR2 at rest 2), skin conductance level (SCL) and non-specific skin conductance response (NS-SCR), by sex

Males/females	RSA	HR1	HR2	SCL	NS-SCR
RSA	1	−.58^*	−.47^*	.02	.05
HR1	−.56^*	1	.85^*	.14^*	.20^*
HR2	−.47^*	.82^*	1	.16^*	.16^*
SCL	.07	.08	.06	1	.58^*
NS-SCR	.11^*	.03	.02	.61^*	1

Females are above the diagonal; RSA, SCL and NS-SCR were square-root transformed,
