Dyslexic children have been shown to be more creative than their non-dyslexic counterparts. They have also been shown to have an abnormal oculomotor profile while viewing targets in free space, making vergence or saccadic eye movements while reading or when viewing Op art. They show a slower deceleration of their eye movements and a difficulty in coordinating their two eyes to obtain single fused vision in depth. Interestingly, their abnormal oculo-motor profile is exacerbated while reading more difficult texts. Given these differences, we postulate that dyslexics' increased creativity may be related to their different eye movement control affecting how they perceive the world. Therefore, we decided to measure adolescent dyslexics' creativity, oculomotor profile, and subjective responses while they viewed three paintings by Magritte. These were chosen to stimulate the perception of hidden conceptual spaces or stimulate conflict between the perception of the figural and textural content. For the first time to our knowledge, dyslexic adolescents were demonstrated to be more creative in terms of flexibility and fluidity than their non-dyslexic peers. Subjectively, while viewing the Magritte paintings, dyslexics reported fewer conceptual spaces and fewer hidden words than their non-dyslexic peers; thus, they confabulated less than non-dyslexics. Dyslexics also demonstrated an abnormal oculomotor profile similar to those that we have shown when reading, viewing randomized targets, and while perceiving illusions of depth in Op art paintings, in that they demonstrated difficulty with disconjugation and abnormalities in their eye velocity profiles. We propose there may be a link between dyslexic increased creativity and their eye movement abnormalities. Similar to reading nonsense text, we propose that Magritte's contradictory paintings exacerbate dyslexics' eye movement abnormalities. These eye movement abnormalities while viewing these particular paintings might provide a physiological signature suggesting a contribution of their unusual eye control to their higher creativity scores.
研究表明,患有诵读困难症的儿童比没有诵读困难症的儿童更具创造力。研究还表明,他们在自由空间中观察目标时存在异常的眼球运动模式,在阅读或观看欧普艺术时会进行辐辏或扫视眼球运动。他们的眼球运动减速较慢,并且在协调双眼以获得深度单一融合视觉方面存在困难。有趣的是,在阅读更难的文本时,他们异常的眼球运动模式会加剧。鉴于这些差异,我们推测诵读困难症患者创造力的提高可能与他们不同的眼球运动控制有关,这会影响他们对世界的感知方式。因此,我们决定在青少年诵读困难症患者观看马格利特的三幅画作时,测量他们的创造力、眼球运动模式和主观反应。选择这些画作是为了激发对隐藏概念空间的感知,或激发图形与纹理内容感知之间的冲突。据我们所知,首次证明诵读困难症青少年在灵活性和流畅性方面比没有诵读困难症的同龄人更具创造力。主观上,在观看马格利特的画作时,诵读困难症患者报告的概念空间和隐藏单词比没有诵读困难症的同龄人少;因此,他们的虚构比非诵读困难症患者少。诵读困难症患者还表现出与我们在阅读、观看随机目标以及感知欧普艺术画作中的深度错觉时所显示的异常眼球运动模式相似,即他们在眼球分离方面存在困难,并且眼球速度曲线存在异常。我们提出诵读困难症患者创造力的提高与他们的眼球运动异常之间可能存在联系。与阅读无意义文本类似,我们提出马格利特的矛盾画作会加剧诵读困难症患者的眼球运动异常。观看这些特定画作时的这些眼球运动异常可能提供一种生理特征,表明他们不寻常的眼球控制对其较高的创造力得分有贡献。
