We recently published the results of a study on the occurrence of blindsight among eight, post-stroke homonymous hemianopic (HH) patients (Garric et al., 2019), in whom we measured blindsight through forced-choice tasks and assessed perceptual experiences by a new awareness scale, the Sensation Awareness Scale (SAS). Within the cohort, we found different profiles of dissociation between objective and subjective performance. Importantly, we were able to describe several cases of a dissociation phenomenon that we named blindsense, whereby patients exhibited marked subjective sensitivity in their blind hemifield despite being unable to discriminate the different stimuli. Following publication of our article (Garric et al., 2019), Prof. Ian Phillips (Phillips, 2019) wrote a Commentary in which he questioned the methodology we used to measure and analyze objective and subjective perception in our HH patients. As opposed to our original interpretation of our results to describe the new profile of blindsense, based on a non-visual experience hypothesis (Kentridge, 2015), Prof. Phillips re-evaluated the different blindsight profiles that we identified in our study through the lens of a degraded conscious vision hypothesis (Overgaard, Fehl, Mouridsen, Bergholt, & Cleeremans, 2008). In the present response, we explain that, although we agree that dichotomous visual scales lead to highly conservative responses and mask conscious perceptual experience of patients, we still support the notion that nuanced report protocols can enable more-sensitive measurements of perceptual experiences in the hemianopic, so-called blind visual field. Furthermore, we affirm that the additional awareness-scale phenomenal levels that such protocols enable are more consistent with patients' experiences and lead patients to provide more liberal responses when describing their subjective perceptions.

讲瞎话：对菲利普斯的答复。

我们最近发表了一项研究结果，研究了八名卒中后同名偏盲（HH）患者中失明的情况（Garric等人，2019），我们在其中通过强制选择任务测量了失明并通过新的意识量表，即感觉意识量表（SAS）。在该队列中，我们发现了客观和主观表现之间的分离关系。重要的是，我们能够描述几种被称为盲感的解离现象的案例，即尽管无法区分不同的刺激，但患者在其盲半场表现出明显的主观敏感性。在发表文章（Garric等人，2019）之后，伊恩·菲利普斯（Ian Phillips）教授（Phillips，2019）写了一篇评论，他质疑我们用来测量和分析HH患者客观和主观感知的方法。与基于非视觉体验假设（Kentridge，2015年）而对结果进行描述以描述盲感的新特征的原始解释相反（Phillip K. Phillips教授重新评估了我们在研究中通过镜头确定的不同盲视特征）意识视觉假说的退化（Overgaard，Fehl，Mouridsen，Bergholt和Cleeremans，2008年）。在本答复中，我们解释说，尽管我们同意二分法视力表会导致高度保守的反应并掩盖患者的自觉知觉体验，但我们仍然支持以下观点：细微差别的报告协议可以实现对半盲者的知觉体验的更敏感的测量，所谓的盲视野。此外，我们确认，此类协议所能实现的额外的认知等级显着水平与患者的体验更加一致，并在描述患者的主观感知时使患者提供更为宽松的反应。
