摘要

在这封观点信中，我通过最近神经科学发现的镜头，批判性地审视了长期以来关于心理意象本质的争论——特别是描绘理论和命题理论之间的紧张关系。虽然早期的神经成像研究被解释为支持一种描述的、类似感知的视觉图像模型，但来自失视症患者的新数据提出了令人信服的反证。这些报告缺乏有意识视觉意象的人，在与意象相关的任务中，在早期视觉皮层显示出可解码的活动，促使人们重新评估将V1的神经激活与主观意象联系起来的假设。我提出了支持人脑中心理表征的单一或双重过程的替代方案。

Revisiting the mental imagery debate: New evidence from aphantasia and neuroimaging

In this viewpoint letter, I critically examine the longstanding debate regarding the nature of mental imagery—specifically the tension between depictive and propositional theories—through the lens of recent neuroscientific findings. While early studies using neuroimaging were interpreted as supporting a depictive, perception-like model of visual imagery, emerging data from individuals with aphantasia present compelling counterevidence. These individuals, who report an absence of conscious visual imagery, nonetheless display decodable activity in early visual cortices during imagery-related tasks, prompting a reevaluation of the assumptions linking neural activation in V1 to subjective imagery. I suggest alternatives that support for a single- or a dual-process account of mental representation in the human brain.

期刊介绍： CORTEX is an international journal devoted to the study of cognition and of the relationship between the nervous system and mental processes, particularly as these are reflected in the behaviour of patients with acquired brain lesions, normal volunteers, children with typical and atypical development, and in the activation of brain regions and systems as recorded by functional neuroimaging techniques. It was founded in 1964 by Ennio De Renzi.
