“…Our findings support the idea that the combination of different features in thermal-tactile perception follows inference processes for the purpose of coherent object perception. Previous work has shown that inferences regarding visual properties change haptic estimates, such as temperature, weight, surface texture and size (Lederman et al, 1986;Ernst and Banks, 2002;Brayanov and Smith, 2010;Ho et al, 2014). TR similarly appears to be driven by a mechanism in which inferences regarding tactile properties change temperature estimates.…”

The brain consistently faces a challenge of whether and how to combine the available information sources to estimate the properties of an object explored by hand. Thermal referral (TR) is a phenomenon that demonstrates how thermal and tactile modalities coordinate to resolve inconsistencies in spatial and thermal information. When the middle three fingers of one hand are thermally stimulated, but only the outer two fingers are heated (or cooled), thermal uniformity is perceived across three fingers.This illusory experience of thermal uniformity in TR compensates for the discontinuity in the thermal sensation across the sites in contact. The neural loci of TR is unclear. While TR reflects the diffuse nature of the thermoceptive system, its similarities to perceptual filling-in and its facilitative role in object perception also suggest that TR might involve inference processes associated with object perception. To clarify the positioning of this thermo-tactile interaction in the sensory processing hierarchy, we used perceptual adaptation and Bayesian decision modelling techniques. Our results indicate that TR adaptation takes place at a peripheral stage where information about temperature inputs are still preserved for each finger, and that the thermal-tactile interaction occurs after this stage. We also show that the temperature integration across three fingers in TR is consistent with precision weighted averaging effect -Bayesian cue combination. Altogether, our findings suggest that for the sensory processing hierarchy of thermal touch, thermal adaptation occurs prior to thermo-tactile integration, which combines thermal and tactile information to give a unified percept to facilitate object recognition.Significance Statement. Thermal touch refers to the perception of temperature of objects in contact with the skin and is key to object recognition based on thermal cues. While object perception is an inference process involving multisensory inputs, thermal referral (TR) is an illusion demonstrating how the brain's interpretation of object temperature can deviate from physical reality. Here we used TR to explore the processing hierarchy of thermal touch. We show that adaptation of thermal perception occurs prior to integration of thermal information across tactile locations. Further, we show that TR results from simple averaging of thermal sensation across locations. Our results illuminate the flexibility of the processing that underlies thermal-tactile interactions and facilitates object exploration and identification in our complicated natural environment.

“…The link between brightness, saturation and size can be explained by the bodily constraint of a nonuniform distribution of photoreceptors across the retina, resulting in different color vision in the periphery compared to vision in the fovea [24]. The association between physical temperature and hue can be explained by the internalization of correlations between stimuli that are present in the environment (like fire, sun, water) and our bodies (blood circulation) [9]. As predicted, multiple McNemar tests (Bonferroni corrected) revealed no difference between the different hues tested across the weight and size conditions.…”

Abstract.Color is a powerful visual property and is used to make interferences about the world. However, no theoretical framework is available that explains precisely where color associations come from and how they affect psychological functioning, making it difficult to predict how color affects human-computer interaction. This paper aims at closing this gap by suggesting an Embodied Cognition view on color, which assumes that the aggregate of our perceptual color experiences is part of the mental representation of tactile object attributes and thus systematically influences our abstract thinking via the process of metaphorical mapping. An empirical study is presented in which hues and saturation of objects were manipulated via Augmented Reality. Participants matched objects to abstract concepts, e.g., happiness. 83% of the participants' choices were correctly predicted, suggesting that color information is considered during the processing of abstract information. Eight color-to-abstractconcept mappings are recommended and possible areas of application are discussed.

“…In such forced-choice reaction time tasks, the participants' full attention is directed to the target stimuli, thus inverting the prediction. Such inverted color effects are typically found in color psychology when single-color evaluations are extended to more applied contexts and interactions [25], thus questioning the transferability of results of basic research to more applied contexts.…”

The discussion of color in HCI often remains restricted to issues of legibility, aesthetics or color preferences. Little attention has been given to the emotional and semantic effects of color on digital content. At the example of black and white, this paper reviews previous studies in psychology and reports an experiment that investigates the influence of black, white and gray user interface backgrounds on the perception of sentiment in chat messages on a social media platform (Twitch.tv). Of sixty-seven participants, those who rated the messages against a black background perceived them more negatively than those who worked against a white background. The results suggest that user sentiment perception can be influenced by interface color, especially for ambiguous textual content laced with irony and sarcasm. We claim that this knowledge can be applied in persuasive interaction and user experience design across the entirety of the digital landscape.
