Is blindsight possible under signal detection theory? Comment on Phillips (2021)
1Centre for Philosophy of Natural and Social Science, London School of Economics and Political Science.
Abstract:
Phillips argues that blindsight is due to response criterion artifacts under degraded conscious vision. His view provides alternative explanations for some studies, but may not work well when one considers several key findings in conjunction. Empirically, not all criterion effects are decidedly nonperceptual. Awareness is not completely abolished for some stimuli, in some patients. But in other cases, it is clearly impaired relative to the corresponding visual sensitivity. This relative dissociation is what makes blindsight so important and interesting.
