Pearson Correlations Among Study Measures Within Participants in the ELBW Group

Measure		1	2	3	4	5
1. Birth weight	---
2. Gestation Age		.34*	---
3. Respiratory Support Level at Birth		−.39* −.23	---
4. Resting Frontal EEG Alpha Asymmetry		.22*	.03	−.08	---
5. ln Baseline Salivary Cortisol		.01	.01	−.08	−.23*	---

Note:

^*p < .05;

time of day was partialled out of all correlations involving the log baseline salivary cortisol measure; EEG power is inversely related to activity so negative scores reflect greater relative right frontal EEG activity.
