“…Secondly, memory colours support colour constancy (Emmerson and Ross 1987 ; Hurlbert and Ling 2005 ; Ling and Hurlbert 2006 ; for a discussion see also Olkkonen et al 2008 ). Thirdly, memory colours are used in colour memory (Ratner and McCarthy 1990 ; Siple and Springer 1983 ; Van Gulick and Tarr 2010 ). When people have to memorise the colour of an object, their memory is led by the object's typical colour.…”

Object Knowledge Modulates Colour Appearance

We investigated the memory colour effect for colour diagnostic artificial objects. Since knowledge about these objects and their colours has been learned in everyday life, these stimuli allow the investigation of the influence of acquired object knowledge on colour appearance. These investigations are relevant for questions about how object and colour information in high-level vision interact as well as for research about the influence of learning and experience on perception in general. In order to identify suitable artificial objects, we developed a reaction time paradigm that measures (subjective) colour diagnosticity. In the main experiment, participants adjusted sixteen such objects to their typical colour as well as to grey. If the achromatic object appears in its typical colour, then participants should adjust it to the opponent colour in order to subjectively perceive it as grey. We found that knowledge about the typical colour influences the colour appearance of artificial objects. This effect was particularly strong along the daylight axis.

“…No significant differences were found (see Supplemental Material ), although it remains a possibility that the stimuli have some mean differences by color category (e.g., in curvature, local contrast, etc.). Note that the neural responses to grayscale objects may be expected to be particularly uniform across object examplars within participants, since color memories have been shown to be biased to prototypical color category membership (for objects: Van Gulick & Tarr, 2010; for color patches: Boynton et al, 1989; Uchikawa & Shinoda, 1996; Bae et al, 2015; see also Bartleson, 1960).…”

Some familiar objects are associated with specific colors, e.g., rubber ducks with yellow. Whether and at what stage neural responses occur to these color associations remain open questions. We tested for frequency-tagged electroencephalogram (EEG) responses to periodic presentations of yellow-associated objects, shown among sequences of non-periodic blue-, red-, and green-associated objects. Both color and grayscale versions of the objects elicited yellow-specific responses, indicating an automatic activation of color knowledge from object shape. Follow-up experiments replicated these effects with green-specific responses, and demonstrated modulated responses for incongruent color-object associations. Importantly, the onset of color-specific responses was as early to grayscale as actually colored stimuli (before 100 ms), the latter additionally eliciting a conventional later response (approximately 140-230 ms) to actual stimulus color. This suggests that the neural representation of familiar objects includes both diagnostic shape and color properties, such that shape can elicit associated color-specific responses before actual color-specific responses occur.

“…Other works (Olkkonen et al 2010; Van Gulick & Tarr 2010) strongly suggest that colour codification entails cognitive categories: generic chromatic qualities cannot be found in any particular thing -they refer to generalisations. Moreover, there is evidence that colour categories are not determined by object reflectance but by the concept of the perceived object, which includes information about its canonical colour (Olkkonen et al 2008).…”

On perception as the basis for object concepts

Within cognitive and developmental psychology, it is commonly argued that perception is the basis for object concepts. According to this view, sensory experiences would translate into concepts thanks to the recognition, correlation and integration of physical attributes. Once attributes are integrated into general patterns, subjects would become able to parse objects into categories. In this article, we critically review the three epistemological perspectives according to which it can be claimed that object concepts depend on perception: state non-conceptualism, content non-conceptualism, and content conceptualism. We show that the three perspectives have problems that make perception inadequate as a conceptual basis. We suggest that the inquiry about the origin and development of object concepts can benefit from a pragmatic perspective that considers objects’ cultural functions as a conceptual foundation. We address this possibility from the theoretical framework of the pragmatics of the object, considering the importance of objects’ functional permanence.
