本研究调查了23名青少年的行为和心理生理特征，他们在自然发生的压力源之前和之后的血压和心率水平不同，在高中英语课上进行了要求的五分钟演讲。测量的特征包括A型行为、敌意和愤怒、特质焦虑、高血压家族史以及对三种标准化实验室应激源（连续减影、星星描记和握力任务）的血压和心率反应。结果表明，焦虑的青少年在公开演讲期间相对于下一堂英语课的收缩压和心率水平升高，而愤怒的青少年舒张压水平升高。那些在执行实验室任务时表现出心血管指标过度增加的青少年在自然发生的压力源期间也达到了血压和/或心率水平的升高，但这种关系的强度在任务和生理参数之间存在差异。由于样本的独特性和规模，这些调查结果应被视为初步结果。
The present investigation examined the behavioral and psychophysiological characteristics of 23 adolescents who differed in levels of blood pressure and heart rate prior to and following a naturally occurring stressor–giving a required five‐minute speech in a high school English class. Measured characteristics were Type A behavior, hostility and anger, trait anxiety, family history of hypertension, and blood pressure and heart rate responses to three standardized laboratory stressors (serial subtraction, star‐tracing, and handgrip tasks). Results showed that anxious adolescents achieved elevated levels of systolic blood pressure and heart rate during public speaking relative to the next English class, whereas angry adolescents achieved elevated levels of diastolic blood pressure. Those adolescents who exhibited exaggerated increases in the cardiovascular measures while performing laboratory tasks also achieved elevated levels of blood pressure and/or heart rate during the naturally occurring stressor, but the strength of the relationships varied across tasks and physiological parameters. These findings should be viewed as tentative because of the uniqueness and size of the sample.
