Topics
Wendy Zuckerman: 人们在一些意想不到的方式上存在差异,例如感知觉想象力的差异。 Lulu: 我拥有感知觉想象力缺失症(Aphantasia),无法在脑海中形成视觉图像,我的‘想象’是抽象的认知,而非视觉图像。我通过采访其他人发现,大多数人闭眼想象苹果时,能够看到颜色和形状,而我的脑海中浮现的是苹果的卡通形象,而非真实的视觉图像。长期以来,人们对精神影像的描述缺乏客观验证方法,双眼竞争实验(Binocular rivalry)和瞳孔对光反射实验可以用来客观地测量视觉想象力。感知觉想象力缺失症(Aphantasia)是指无法在脑海中形成视觉图像的现象,而超级感知觉想象力(Hyperphantasia)是指能够在脑海中形成极其生动视觉图像的现象。我非常羡慕拥有超级感知觉想象力的人,因为他们能够更生动地回忆和感受记忆,甚至可以沉浸在想象的世界中。 Latif: 我的视觉想象力不如其他人清晰,我的脑海中浮现的是苹果的卡通形象。 Mark Whitman: 闭上眼睛想象红苹果,你能否描述你“看到”的内容? Joel Pearson: 想象图像会影响双眼竞争实验的结果,想象力会影响视觉感知,而感知觉想象力缺失症患者则没有这种反应。通过刺激大脑视觉皮层,可以增强人的视觉想象力,但对于感知觉想象力缺失症患者,增强视觉想象力需要更复杂的方法和更长的训练时间。突然获得视觉想象力可能存在风险。 Derek: 我拥有超级感知觉想象力,我的想象力极其生动,可以体验到各种感官体验,甚至可以将想象中的事物投射到现实世界中。过度的想象力可能导致无法区分现实和虚幻。 Emily Holmes: 高度的视觉想象力可能与焦虑症和创伤后应激障碍等疾病相关,但视觉想象力强弱与精神疾病之间并非简单的因果关系。可以通过训练来控制超级感知觉想象力。 Robert: 只有人类能够将现实世界的图像进行抽象化处理。

Deep Dive

Chapters
The episode starts by exploring individual differences in mental imagery. The host introduces the concept of aphantasia, the inability to visualize mental images, contrasting it with the vivid imagery experienced by others. The discussion delves into the nature of mental imagery, questioning the very definition of "seeing" in the mind.
  • Aphantasia is the inability to create mental images.
  • Individuals experience mental imagery with varying degrees of vividness.
  • The nature of "seeing" in the mind is subjective and open to interpretation.
