Descriptive statistics and correlations between primary variables

Measure	Mean (SD)	Range	t	1	2	3	4	5	6	7
1. Startle (neutral)	52.09 (3.48)	41.82–58.38	0.40	–
2. Startle (positive)	47.94 (2.86)	45.21–61.17	−0.49	−0.05	–
3. Startle (negative)	51.79 (3.28)	41.60–56.70	0.63	−0.13	−0.24†	–
4. Behavioral inhibition	93.81 (28.73)	43.90–173.57	−0.54	0.32*	−0.05	0.03	–
5. CBCL anxiety problems	53.46 (5.61)	50.00–73.00	−0.29	0.10	−0.06	−0.08	0.25†	–
6. Child age (years)	5.91 (1.11)	3.75–7.92	−0.75	−0.12	−0.08	−0.09	−0.13	−0.14	–
7. Child gender	34F; 30 M	–	–	−0.05	0.06	−0.08	0.08	0.03	0.10	–

Note: n = 64. Descriptive statistics are computed from a mean of ten imputed datasets; correlations and t-tests are derived from a pooling of imputations. Startle refers to the mean of within-subjects t-scores of a condition relative to all other valid trials in the experiment. CBCL anxiety problems referenced are T-scores. t = independent-samples t tests of gender differences. SD = standard deviation.
