In Sync: The Effect of Physiology Feedback on the Match between Heart Rate and Self-Reported Stress

Figure 3

Average correlations (left) and difference scores (right) between different variables for the different feedback types. A higher correlation means a stronger match between two variables, while the reverse is true for the difference scores. For the sake of readability, feedback types are coded as 1 = measurement-only, 2 = HR-feedback, and 3 = stress-feedback.

(a) Correlation between heart rate and momentary stress

(b) Difference score for heart rate and momentary stress

(c) Correlation between heart rate and retrospective stress

(d) Difference score for heart rate and retrospective stress

(e) Correlation between momentary and retrospective stress

(f) Difference score for momentary and retrospective stress
