This study examined the psychological processes that may impede or facilitate cardiovascular recovery. It was hypothesized that cardiovascular recovery would be hampered by negative affect and rumination, and facilitated by positive affect. In an experimental study, stress was elicited by exposing participants (N=110) to a mental arithmetic task with harassment. After the stress task, affective levels were manipulated via a movie scene with negative, neutral, or positive emotional valence, or without an affect manipulation (control condition). During the entire experiment, heart rate and systolic and diastolic blood pressure levels were measured continuously. Results indicated that blood pressure recovery was hampered by the negative affect manipulation and by rumination. However, the positive affect manipulation did not facilitate blood pressure recovery. No effects were found on heart rate recovery. In sum, the findings emphasize the importance of negative affect and rumination in stress recovery.
本研究探讨了可能阻碍或促进心血管恢复的心理过程。研究假设心血管恢复会受到负性情绪和反刍的阻碍，而受到正性情绪的促进。在一项实验研究中，通过让参与者（N=110）进行带有骚扰的心理算术任务来引发压力。在应激任务之后，通过观看带有负性、中性或正性情绪效价的电影片段或不进行情绪处理（控制条件）来操纵情绪水平。在整个实验过程中，连续测量心率和收缩压及舒张压水平。结果表明，血压恢复受到负性情绪处理和反刍的阻碍。然而，正性情绪处理并没有促进血压恢复。对心率恢复没有影响。总之，这些发现强调了负性情绪和反刍在应激恢复中的重要性。
