TABLE 2.
Manipulation check outcomes for alpha-amylase (AA), heart rate (HR), cortisol (CORT), and situational anxiety (STAI-S) scores, including mean differences and the results of independent samples t-tests, with effect size in Cohen’s D.
Outcome measure | Mean difference | t-test result |
Alpha amylase | 39.1 U/mL | t(44) = 3.01, p < 0.01, Cohen’s D = 1.54 |
Heart rate | 19.84 BPM | t(34) = 9.09, p < 0.001, Cohen’s D = 0.44 |
Respiration rate | 0.61 BPM | t(36) = 1.13, p = 0.27, Cohen’s D = 0.19 |
Cortisol | 0.28 μg/dL | t(45) = 3.39, p < 0.01, Cohen’s D = 0.5 |
STAI-S | 8.52 points | t(45) = 6.32, p < 0.001, Cohen’s D = 0.93 |
