“…In line with earlier findings, our results provided evidence for a colour-diagnosticity effect: HCD objects were consistently named more slowly than LCD objects. This finding is in accordance with results from the literature (e.g., Bramão et al, 2010;Redmann et al, 2014;Tanaka & Presnell, 1999;Therriault et al, 2009). A possible reason for this detrimental effect of high colour-diagnosticity on naming lies in the fact that HCD objects tend to be structurally more similar to each other than LCD objects: Different kinds of fruit or vegetables, which are often colour-diagnostic to a high degree, are more similar in shape than, for instance, different tools or vehicles, which are mostly LCD (Laws & Hunter, 2006;Tanaka & Presnell, 1999).…”

“…In line with earlier findings, Experiment 1 showed a clear reaction time effect of colour-diagnosticity: HCD objects were named more slowly than LCD objects. This finding replicates the results from Redmann et al (2014) and other studies in the literature (e.g., Bramão, Faísca, Petersson, & Reis, 2010;Tanaka & Presnell, 1999). Note that even though a direct comparison between HCD and LCD objects was not possible in the present study, other studies have found that presentation of the object with and without correctly coloured surface differently affected HCD and LCD objects (e.g., Bramão et al, 2010;Redmann et al, 2014).…”

The time course of colour congruency effects in picture naming

In our interactions with people and objects in the world around us, as well as in communicating our thoughts, we rely on the use of conceptual knowledge stored in long-term memory. From a frame-theoretic point of view, a concept is represented by a central node and recursive attribute-value structures further specifying the concept. The present study explores whether and how the activation of an attribute within a frame might influence access to the concept's name in language production, focussing on the colour attribute. Colour has been shown to contribute to object recognition, naming, and memory retrieval, and there is evidence that colour plays a different role in naming objects that have a typical colour (high colour-diagnostic objects such as tomatoes) than in naming objects without a typical colour (low colour-diagnostic objects such as bicycles). We report two behavioural experiments designed to reveal potential effects of the activation of an object's typical colour on naming the object in a picture-word interference paradigm. This paradigm was used to investigate whether naming is facilitated when typical colours are presented alongside the to-be-named picture (e.g., the word "red" superimposed on the picture of a tomato), compared to atypical colours (such as "brown"), unrelated adjectives (such as "fast"), or random letter strings. To further explore the time course of these potential effects, the words were presented at different time points relative to the to-be-named picture (Exp. 1: −400 ms, Exp. 2: −200 ms, 0 ms, and + 200 ms). By including both high and low colour-diagnostic objects, it was possible to explore whether the activation of a colour differentially affects naming of objects that have a strong association with a typical colour. The results showed that (pre-)activation of the appropriate colour attribute facilitated naming compared to an inappropriate colour. This was only the case for objects closely connected with a typical colour. Consequences of these findings for frame-theoretic accounts of conceptual representation are discussed.

“…Previous research provided compelling evidence that color information improves object recognition (Bramão, Faísca, Petersson, & Reis, 2010;Rossion & Pourtois, 2004;Vernon & Lloyd-Jones, 2003;Wurm et al, 1993). Here we found that color representations significantly increased the two-dimensional object naming performance in both age-and reading-matched controls.…”

ABSTRACT. In the present study, the authors investigate how some visual factors related to early stages of visual-object naming modulate naming performance in dyslexia. The performance of dyslexic children was compared with 2 control groups-normal readers matched for age and normal readers matched for reading level-while performing a discrete naming task in which color and dimensionality of the visually presented objects were manipulated. The results showed that 2-dimensional naming performance improved for color representations in control readers but not in dyslexics. In contrast to control readers, dyslexics were also insensitive to the stimulus's dimensionality. These findings are unlikely to be explained by a phonological processing problem related to phonological access or retrieval but suggest that dyslexics have a lower capacity for coding and decoding visual surface features of 2-dimensional representations or problems with the integration of visual information stored in long-term memory.

“…Color vision helps us to reliably and quickly identify objects within a scene (Brama˜o, Reis, Petersson, & Faísca, 2011;Tanaka, Weiskopf, & Williams, 2001), both for conditions in which the color of the object is diagnostic for that object (i.e., a yellow banana; Tanaka & Presnell, 1999) as for conditions for which color information is not diagnostic for a particular object, for example a yellow sock (Biederman & Ju, 1988;Brama˜o, Faísca, Petersson, & Reis, 2010;Gegenfurtner & Rieger, 2000;Uttl, Graf, & Santacruz, 2006;Wurm, Legge, Isenberg, & Luebker, 1993). For perceived surface color to be a useful guide to object identity, it should highly correlate with surface reflectance.…”

The effects of surface gloss and roughness on color constancy for real 3-D objects

Color constancy denotes the phenomenon that the appearance of an object remains fairly stable under changes in illumination and background color. Most of what we know about color constancy comes from experiments using flat, matte surfaces placed on a single plane under diffuse illumination simulated on a computer monitor. Here we investigate whether material properties (glossiness and roughness) have an effect on color constancy for real objects. Subjects matched the color and brightness of cylinders (painted red, green, or blue) illuminated by simulated daylight (D65) or by a reddish light with a Munsell color book illuminated by a tungsten lamp. The cylinders were either glossy or matte and either smooth or rough. The object was placed in front of a black background or a colored checkerboard. We found that color constancy was significantly higher for the glossy objects compared to the matte objects, and higher for the smooth objects compared to the rough objects. This was independent of the background. We conclude that material properties like glossiness and roughness can have significant effects on color constancy.
