Key result
Larger cardiovascular responses to laboratory stressors were associated with greater cardiovascular responses to classroom speeches, with associations strengthening when measures were aggregated.
Why the study?
Does aggregating multiple occasions of measurement improve the laboratory-to-life generalizability of cardiovascular reactivity to psychological stress?

Does aggregating multiple occasions of measurement improve the laboratory-to-life generalizability of cardiovascular reactivity to psychological stress?
Aggregating multiple measurements of cardiovascular reactivity improves the ability of laboratory stress tests to predict cardiovascular responses to real-world psychological stressors.
Kamarck et al. (2000) reported an observational. Laboratory measures of stress-related cardiovascular reactivity was evaluated on Cardiovascular responses to classroom speeches. Larger cardiovascular responses to laboratory stressors were associated with greater cardiovascular responses to classroom speeches, with associations strengthening when measures were aggregated.
