Word retrieval difficulty can be distressing for individuals with aphasia. However, physiological stress responses to word retrieval are relatively unstudied. This study aims to measure the physiological response (i.e., heart rate and respiratory rate) and perceived stress in individuals with aphasia during a naming task to understand whether word retrieval may be a stressor to them.
An aphasia group (n = 7) and a healthy group (n = 38) participated in 4 experimental conditions, including rest, counting, and high-frequency and low-frequency word conditions, while their physiological parameters were measured throughout the sessions. Stress ratings were also obtained for each condition.
Significant differences in heart rate were found while participants were engaged in speech and/or language tasks, compared to the rest condition, for both groups. Significant differences in respiratory rate were found between the rest and low-frequency word conditions in the aphasia group. No significant difference was found in heart rate between 2 groups, but a difference in respiratory rate was found between 2 groups in the low-frequency word condition. There were some discrepancies between stress level and physiological parameters.
Individuals with aphasia perceived greater stress in the naming tasks, however, the perceived stress was not necessarily parallel to the physiological parameters.
对于失语症患者来说，单词检索困难可能会令人痛苦。然而，对于单词检索的生理应激反应的研究还相对较少。本研究旨在测量失语症患者在命名任务期间的生理反应（即心率和呼吸率）和感知到的压力，以了解单词检索是否对他们构成压力源。
7 名失语症患者和 38 名健康对照者参加了 4 种实验条件，包括休息、计数和高频词及低频词条件，同时在整个过程中测量了他们的生理参数。还对每个条件下的压力评分进行了评估。
与休息条件相比，两组参与者在进行言语和/或语言任务时，心率都有显著差异。在失语症组中，休息和低频词条件之间的呼吸率有显著差异。两组的心率没有显著差异，但在低频词条件下，两组的呼吸率存在差异。压力水平和生理参数之间存在一些差异。
失语症患者在命名任务中感知到更大的压力，但感知到的压力并不一定与生理参数平行。
