Recognition is one of the most ambivalent concepts in political and social thought. While it is a condition for individual freedom, the subject’s demand for recognition can be exploited as an instrument for reproducing domination. Axel Honneth addresses this issue and offers the concept of ideological recognition: Recognition is ideological when the addressees accept it from their subjective point of view but is unjustified from an objective point of view. Using the examples of the recognition of femininity, I argue that (...) Honneth’s account fails not only to offer the objective normative standard that delineates between morally justified and unjustified recognition, but also to descriptively explain why the addressees of ideological recognition accept their identities as having positive qualities. To overcome these problems, I provide an alternative, epistemic structural account. First, my account offers the concept of epistemic trust and identifies the objective injustice that Honneth’s account cannot capture. Second, my account offers the concept of structural power and discusses the problem of internalization of problematic identities. Furthermore, I argue that epistemic structural account has theoretical and practical benefits for analyzing domination and advancing the task of critique by explaining the ideological recognition in the case of racial identity, for example.

Metacontrast is a visual illusion in which the visibility of a target stimulus is virtually lost when immediately followed by a nonoverlapping mask stimulus. For a colored target, metacontrast is color-selective, with target visibility markedly reduced when the mask and target are the same color, but only slightly reduced when the colors differ. This study investigated neural correlates of color-selective metacontrast for cone-opponent red and green stimuli in the human V1, V2, and V3 using functional magnetic resonance imaging. Neural activity (...) was suppressed when the target was rendered less visible by the same-colored mask, and the suppression was localized in the cortical region retinotopically representing the target, correlating with the perceptual topography of visibility/invisibility rather than the physical topography of the stimulus. Retinotopy-based group analysis found that activity suppression was statistically significant for V2 and V3 and that its localization to the target region was statistically significant for V2. These results suggest that retinotopic color representations in early visual areas, especially in V2, are closely linked to the visibility of color. (shrink)

When dissimilar images are presented to the two eyes, binocular rivalry (BR) occurs, and perception alternates spontaneously between the images. Although neural correlates of the oscillating perception during BR have been found in multiple sites along the visual pathway, the source of BR dynamics is unclear. Psychophysical and modeling studies suggest that both low- and high-level cortical processes underlie BR dynamics. Previous neuroimaging studies have demonstrated the involvement of high-level regions by showing that frontal and parietal cortices responded time locked (...) to spontaneous perceptual alternation in BR. However, a potential contribution of early visual areas to BR dynamics has been overlooked, because these areas also responded to the physical stimulus alternation mimicking BR. In the present study, instead of focusing on activity during perceptual switches, we highlighted brain activity during suppression periods to investigate a potential link between activity in human early visual areas and BR dynamics. We used a strong interocular suppression paradigm called continuous flash suppression to suppress and fluctuate the visibility of a probe stimulus and measured retinotopic responses to the onset of the invisible probe using functional MRI. There were ∼130-fold differences in the median suppression durations across 12 subjects. The individual differences in suppression durations could be predicted by the amplitudes of the retinotopic activity in extrastriate visual areas (V3 and V4v) evoked by the invisible probe. Weaker responses were associated with longer suppression durations. These results demonstrate that retinotopic representations in early visual areas play a role in the dynamics of perceptual alternations during BR. (shrink)
