急性精神应激源可能通过增加注意力分散和降低工作记忆功能而对神经心理测试成绩产生不利影响。本研究检查了25名受试者，没有已知的神经或精神损害的简短电池的神经心理学措施，隔日休息或诱导的精神压力，在平衡的设计。成套测试包括Rey听觉-言语学习测试、Rey复杂图形和三个韦氏记忆量表-III子测试（逻辑记忆、数字广度和视觉记忆广度）。平均年龄24.8岁（S.D. = 10.1），平均受教育年限为15.0年（S.D. = 1.6）。心理压力源采用的是一个录像公开演讲的练习，已被证明在以前的工作，以诱导负面情绪，心血管反应，和感知的精神压力。受试者在应激后表现出消极情绪、心率、舒张压和收缩压的统计学显著性（P <0.05）增加，以及皮质醇浓度升高，表明肾上腺皮质反应性和心血管应激反应显著增加。然而，当压力与休息日进行比较时，在任何神经心理学测量方面都没有统计学显著差异。结果表明，急性精神压力可能对正常人群中选定的神经心理学测试的后续表现没有可测量的影响。进一步的工作建议，以确定是否预先存在的焦虑相关的精神病理学或预先存在的神经妥协可能与诱导的精神压力，导致神经心理测试性能下降。(C)2003年美国国家神经心理学学会。由爱思唯尔有限公司出版。保留所有权利。
Acute mental stressors have been implicated as variables that may deleteriously affect neuropsychological test performance by increasing distractibility and decreasing working memory function. This study examined 25 subjects with no known neurological or psychiatric impairment on a brief battery of neuropsychological measures on alternate days following either rest or induced mental stress in a counterbalanced design. The test battery consisted of the Rey Auditory-Verbal Learning Test, the Rey Complex Figure, and three Wechsler Memory Scale-III subtests (Logical Memory, Digit Span, and Visual Memory Span). The Ss average age was 24.8 years (S.D. = 10.1) and average education was 15.0 years (S.D. = 1.6). The mental stressor employed was a videotaped public-speaking exercise that has been shown in previous work to induce negative mood, cardiovascular reactivity, and perceived mental stress. Ss demonstrated statistically significant (P < .05) increases in negative mood, heart rate, diastolic blood pressure, and systolic blood pressure as well as elevated cortisol concentration following induced stress, suggesting substantially increased adrenocortical reactivity and cardiovascular stress response. There were, however, no statistically significant differences in any of the neuropsychological measures when stress versus rest days were compared. The results suggest that acute mental stressors may have no measurable effect on subsequent performance on selected neuropsychological tests in a normal population. Further work is suggested to determine whether pre-existing anxiety-related psychopathology or pre-existing neurological compromise might interact with induced mental stress to cause decrements in neuropsychological test performance.
