The quality space hypothesis about conscious experience proposes that conscious sensory states are experienced in relation to other possible sensory states. For instance, the colour red is experienced as being more like orange, and less like green or blue. Recent empirical findings suggest that subjective similarity space can be explained in terms of similarities in neural activation patterns. Here, we consider how localist, workspace, and higher-order theories of consciousness can accommodate claims about the qualitative character of experience and functionally support a quality space. We review existing empirical evidence for each of these positions, and highlight novel experimental tools, such as altering local activation spaces via brain stimulation or behavioural training, that can distinguish these accounts.

意识的质量空间计算


关于意识体验的质量空间假设提出，意识感觉状态的体验是与其他可能的感觉状态相关的。例如，红色被体验为更像橙色，而不像绿色或蓝色。最近的实证研究结果表明，主观相似性空间可以用神经激活模式的相似性来解释。在这里，我们考虑地方主义、工作空间和高阶意识理论如何适应有关体验的定性特征的主张，并在功能上支持优质空间。我们回顾了每个立场的现有经验证据，并强调了新颖的实验工具，例如通过大脑刺激或行为训练改变局部激活空间，可以区分这些帐户。
