Abstract:
The vividness of imagery varies between individuals. However, the existence of people in whom conscious, wakeful imagery is markedly reduced, or absent entirely, was neglected by psychology until the recent coinage of \'aphantasia\' to describe this phenomenon. \'Hyperphantasia\' denotes the converse - imagery whose vividness rivals perceptual experience. Around 1% and 3% of the population experience extreme aphantasia and hyperphantasia, respectively. Aphantasia runs in families, often affects imagery across several sense modalities, and is variably associated with reduced autobiographical memory, face recognition difficulty, and autism. Visual dreaming is often preserved. Subtypes of extreme imagery appear to be likely but are not yet well defined. Initial results suggest that alterations in connectivity between the frontoparietal and visual networks may provide the neural substrate for visual imagery extremes.
摘要:
图像的生动程度因人而异。然而,有意识的人的存在,清醒的图像显着减少,或者完全缺席,一直被心理学所忽视,直到最近的造币“阿凡达”来描述这种现象。“Hyperphantasia”表示相反的意象,其生动度可与感知体验相媲美。大约1%和3%的人口经历过极度的神速扩张和神速扩张,分别。Aphantasia在家庭中生活,通常会影响几种感觉模式的图像,并且与减少的自传记忆有不同的联系,人脸识别难度,和自闭症。视觉梦经常被保存。极端图像的子类型似乎很可能,但尚未明确定义。初步结果表明,额叶和视觉网络之间的连通性改变可能为视觉图像极限提供神经基础。
