Visual mental imagery is the ability to create a quasi-perceptual visual picture in the mind's eye. For people with the rare trait of aphantasia, this ability is entirely absent or markedly impaired. Here, we aim to clarify the prevalence of aphantasia in the general population, while overcoming limitations of previous research (e.g., recruitment biases). In Experiment 1, we screened a cohort of undergraduate students (n502) using the Vividness of Visual Imagery Questionnaire (Marks, 1973) and found that 4.2% had aphantasia. To establish the reliability of our estimate, we then screened a new sample of people (n502) at an online crowdsourcing marketplace, again finding that approximately four percent (3.6%) had aphantasia. Overall, our combined prevalence from over a thousand people of 3.9% - which shows no gender bias - provides a useful index for how commonly aphantasia occurs, based on measures and diagnostic thresholds in line with contemporary aphantasia literature.
视觉表象是在脑海中创造出近乎感知的视觉图像的能力。对于那些具有罕见的无像力特质的人来说，这种能力完全不存在或明显受损。在这里，我们旨在澄清无像力在普通人群中的流行程度，同时克服以往研究的局限性（例如，招募偏见）。在实验 1 中，我们使用生动的视觉意象问卷（Marks，1973）筛选了一组本科生（n502），发现有 4.2%的人具有无像力。为了确定我们估计的可靠性，我们随后在一个在线众包市场上筛选了另一组新的人群（n502），再次发现大约有 4%（3.6%）的人具有无像力。总的来说，我们从一千多人中得出的综合流行率为 3.9%，没有性别偏见，这为无像力的发生频率提供了一个有用的指标，该指标基于与当代无像力文献一致的测量和诊断标准。
