大脑皮质的功能活动是人的心理活动的生理基础。有些演员由于各种心理因素而引起嗓音的变化,这在我们艺术嗓音的普查及日常工作中是经常遇到的。有的演员声带上虽有轻微病变,但能照常演出,嗓音也较好;而一旦知道声带有病,嗓音立即变坏,这也是由于心理不健康所致。大量的研究已表明,人的心理因素同人的健康疾病的产生和医治、工作效率的高低都有紧密联系,因此心理学已广泛地被应用于体育、教育、医学、军事等 Functional activity of the cerebral cortex is the physiological basis of human psychological activity. Some actors cause changes in their voice due to various psychological factors, which are often encountered in the census and daily work of our artistic voice. Although some performers had mild lesions on the vocal cords, they performed well as usual and their voice was better. However, once they learned that the vocal cords were sick, the voice immediately deteriorated. This was also due to the unhealthy mentality.
