Abstract This article has two aims: (i) to bring Judith Butler and Wilfrid Sellars into conversation; and (ii) to argue that Butler's poststructuralist critique of feminist identity politics has metaphilosophical potential, given her pragmatic parallel with Sellars's critique of conceptual analyses of knowledge. With regard to (i), I argue that Butler's objections to the definitional practice constitutive of certain ways of construing feminism is comparable to Sellars's critique of the analytical project geared toward providing definitions of knowledge. Specifically, I propose that moving away from a definition of woman to what one may call poststructuralist sites of woman parallels moving away from a definition of knowledge to a pragmatic account of knowledge as a recognizable standing in the normative space of reasons. With regard to (ii), I argue that the important parallels between Butler's poststructuralist feminism and Sellars's antirepresentationalist normative pragmatism about knowledge enable one to think of her poststructuralist feminism as mapping out pragmatic cognitive strategies and visions for doing philosophy. This article starts a conversation between two philosophers whom the literature has yet to fully introduce to each other.

Recent Duplication

The disabilities experienced by colour-blind people show us the biological advantages of colour vision in detecting targets, in segregating the visual field and in identifying particular objects or states. Human dichromats have especial difficulty in detecting coloured fruit against dappled foliage that varies randomly in luminosity; it is suggested that yellow and orange tropical fruits have co-evolved with the trichromatic colour vision of Old World monkeys. It is argued that the colour vision of man and of the Old World monkeys depends on two subsystems that remain parallel and independent at early stages of the visual pathway. The primordial subsystem, which is shared with most mammals, depends on a comparison of the rates of quantum catch in the short- and middle-wave cones; this system exists almost exclusively for colour vision, although the chromatic signals carry with them a local sign that allows them to sustain several of the functions of spatiochromatic vision. The second subsystem arose from the phylogenetically recent duplication of a gene on the X-chromosome, and depends on a comparison of the rates of quantum catch in the long- and middle-wave receptors. At the early stages of the visual pathway, this chromatic information is carried by a channel that is also sensitive to spatial contrast. The New World monkeys have taken a different route to trichromacy: in species that are basically dichromatic, heterozygous females gain trichromacy as a result of X-chromosome inactivation, which ensures that different photopigments are expressed in two subsets of retinal photoreceptor.

Road Sign comprehension studies typically focus on differences among signs, demonstrating large variability in comprehension among different signs. Differences in features of sign design can be grouped into their shape, background color, and the symbol/icon in their center. This study demonstrated that specific sign messages can be presented with different sign features without detrimental effects on either comprehension level or response time. In particular, the choice of background color (yellow or white) appears to be inconsequential for comprehension. It seems that some sign characteristics are not critical to comprehension and consequently licensed drivers may even incorrectly identify a non-local sign as the standard sign that they actually encounter on the roads. However, other sign features – especially those relating to the icon/symbol - can be critical to comprehension when they violate the icon-concept compatibility, as it is represented in drivers' long-term memory.

Prior Adaptation

The existence of multiple channels, or multiple receptive field sizes, in the visual system does not commit us to any particular theory of spatial encoding in vision. However, distortions of apparent spatial frequency and width in a wide variety of conditions favour the idea that each channel carries a width- or frequency-related code or ‘label’ rather than a ‘local sign’ or positional label. When distortions of spatial frequency occur without prior adaptation (e.g. at low contrast or low luminance) they are associated with lowered sensitivity, and may be due to a mismatch between the perceptual labels and the actual tuning of the channels. A low-level representation of retinal space could be constructed from the spatial information encoded by the channels, rather than being projected intact from the retina.

Purpose Key word signing (KWS) entails using manual signs to support the natural speech of individuals with normal hearing and who have communication difficulties. While manual signs from the local sign language may be used for this purpose, some KWS systems have opted for a distinct KWS lexicon. Distinct KWS lexicon typically aims for higher sign iconicity or recognizability to make the lexicon more accessible for individuals with intellectual disabilities. We sought to determine if, in the Belgian Dutch context, signs from such a distinct KWS lexicon (Spreken Met Ondersteuning van Gebaren [Speaking With Support of Signs; SMOG]) were indeed more iconic than their Flemish Sign Language (FSL) counterparts. Method Participants were 224 adults with typical development who had no signing experience. They rated the resemblance between a FSL sign and its meaning. Raw data on the iconicity of SMOG from a previous study were used. Translucency was statistically and qualitatively compared between the SMOG lexicon and their FSL counterparts. Results SMOG had an overall higher translucency than FSL and contained a higher number of iconic signs. Conclusion This finding may support the value of a separate sign lexicon over using sign language signs. Nevertheless, other aspects, such as wide availability and inclusion, need to be considered.
