本文追溯了口述历史的认识论在20世纪的两次转向,即在衡量口述历史价值和意义时,从以史料内容的真实性为中心的客观性迷思,到以史料生产过程为中心的叙事转向,再至以口述者自我呈现及口述访谈关系性为中心的表演转向。同时,本文勾勒了1980年代开始广泛使用的数字视听影像技术对于表演转向的意义。本文认为,影像化的口述证言是视听影像与口述历史结合后产生的一种重要的历史表达形态。 This essay traces back to the two turns of epistemology of oral history in the 20th century, that is, from the objective myth centered on the authenticity of historical materials to the narrative centered on the historical material production process when measuring the oral historical value and significance , And then turned to performances centered on the oral self-presentation and oral interview. At the same time, this article sketches the significance of the digital audio-visual video technology widely used in the 1980s for the turning of performances. This article argues that the visual oral evidence is an important form of historical expression that results from the combination of audio-visual images and oral history.
