The Rycroft-Malone paper states that co-production relies on 'authentic' collaboration as a context for action. Our commentary supports and extends this assertion. We suggest that 'authentic' co-production involves processes where participants can 'see' the difference that they have made within the project and beyond. We provide examples including: the use of design in health projects which see...

A widely-viewed image of a dress elicits striking individual variation in colour perception. Experiments with multiple variants of the image suggest that the individual differences may arise through the action of visual mechanisms that normally stabilise object colour.

Williams, Brannan and Lartigue (1987) (Clinical Vision Science, 1, 367-371) reported that poor readers took significantly longer to search letter arrays for a target than did good readers. In addition, they reported that blurring the letter arrays leads to faster search times for poor readers and a loss of the significant differences between the groups seen with unblurred displays. In a recent ...

Nearly all of today's confident dismissals of the notion of a "post-racial" America address the simple question, "Are we beyond racism or not?" But most of the writers who have used the terms post-racial or post-ethnic sympathetically have explored other questions: What is the significance of the blurring of ethnoracial lines through cross-group marriage and reproduction? How should we interpre...

A quantitative analysis of blurring and its dependence on the stencil-substrate gap and the deposition parameters in stencil lithography, a high resolution shadow mask technique, is presented. The blurring is manifested in two ways: first, the structure directly deposited on the substrate is larger than the stencil aperture due to geometrical factors, and second, a halo of material is formed su...

How does the nervous system store a newly experienced visual pattern, and how is that pattern subsequently made available for recognition? Recent work in Drosophila suggests that specific pattern features are stored separately in the nervous system.

Our perception of a surface's colour depends in a complex way on the colours of surrounding surfaces; this "colour contrast' is linked to the "colour constancy' which is important for object recognition, but in ways more complex than we yet understand.

Previous research suggests that face recognition may involve both configurational and piecemeal (featural) processing. To explore the relationship between these processing modes, we examined the patterns of recognition impairment produced by blurring, inversion, and scrambling, both singly and in various combinations. Two tasks were used: recognition of unfamiliar faces (seen once before) and r...
