Children's responses to cognitive challenge and links to self-reported rumination.

We tested the hypothesis that less effective responses during a cognitive challenge would relate to higher levels of self-reported rumination in children. The sample was 100 children (55 boys, 45 girls), aged 7 to 14 years. A portion (n=65) was at high risk for depression due to having a parent with a childhood-onset mood disorder, and 35 were a low-risk comparison group.

Biofeedback of heart rate variability and related physiology: a critical review.

Low heart rate variability (HRV) characterizes several medical and psychological diseases. HRV biofeedback is a newly developed approach that may have some use for treating the array of disorders in which HRV is relatively low. This review critically appraises evidence for the effectiveness of HRV and related biofeedback across 14 studies in improving (1) HRV and baroreflex outcomes and (2) clinical outcomes.

The influence of forgiveness and apology on cardiovascular reactivity and recovery in response to mental stress.

To investigate the relation between forgiveness and apology as they relate to cardiovascular reactivity and recovery, 29 men and 50 women were exposed to an interpersonal transgression (i.e., verbal harassment) while performing a serial subtraction task.
