Table 2. Correlations (Age Partialed) Between Children's Physiological Reactivity Scores and Fire Alarm Session 1 Memory Performance (Autonomic dfs = 60 or 61; Cortisol dfs = 36 to 39).

	Free-recall correct units	Direct question proportion correct
Autonomic scores
PEP difference	.11	.05
RSA difference	−.11	.29*
Reactivity index	.03	.12
Cortisol scores
Time 1	.03	.27†
Time 2	.06	.25†
Cortisol difference	−.01	−.08

Note. PEP = pre-ejection period, RSA = respiratory sinus arrhythmia. For PEP and RSA difference scores, greater values reflect lower reactivity. The reactivity index is a composite score, with higher values corresponding to greater sympathetic activation and parasympathetic withdrawal.
