Manning Nguyen: 我一直以来都能在脑海中看到图像，并认为这是理所当然的。直到我与Alice Coles交谈后，我才意识到并非所有人都能做到这一点。 Alice Coles: 我的大脑里总是有很多文字，但没有图像。我无法在脑海中看到我爱的人的脸或我在英国的老房子。当我发现其他人可以在脑海中看到图像时，我感到失落和嫉妒。但现在我认为这是一种优势，我可以不受脑海中弹出的图像的束缚，进行更多的探索，并且可以帮助我平静思绪。 Adam Zeman: Aphantasia指的是缺乏想象能力。患者可能因为脑损伤或心理原因而患上此病。终身Aphantasia的机制尚不清楚，可能与某些疾病有关，也可能与遗传有关。Aphantasia不仅仅是一种单一的现象，而是一种经验上的变异，可能发生在多种情况下。 Joel Pearson: 视觉图像是在视觉皮层中形成的，与外部世界无关。可视化与视觉密切相关，涉及大脑中相似区域的激活。想象明亮的事物会导致瞳孔收缩，想象黑暗的事物会导致瞳孔放松。想象力越强，对视觉细节的反应越强烈。我们开发了客观可靠的技术来测量视觉想象力。
