“…In order to effectively design surface textures of products, it is crucial to understand the causal relationships among these different types of texture-related experiences. Especially because emotional and personal experiences significantly influence the value of a product, many studies have investigated experiences of pleasantness, comfort, and preference for product design purposes [1][2][3][4][5].…”

Abstract:To effectively design tactile textures of product surfaces, it is essential to specify the semantically multilayered and multidimensional structure of human perceptual, emotional, and preferential expressions pertaining to touching materials. We implemented a method to identify individual differences in the structure of these expressions, based on subjective reports of the mutual impacts among 29 adjective dyads used to describe tactile experiences of material samples. Results showed that the 11 university students who responded to 46 types of flat materials were clustered into three statistically different groups. The structures were largely composed of three layers of expressions: psychophysical (bottom), emotional or material attributes (middle), and preferential (top). All groups selected the same adjective dyads encompassed in the bottom layer, relating to percepts of physical quantities, which indicates the similarity of psychophysical percepts among the participants; however, the middle and top layers significantly differed across individuals. These results indicate that under the tested conditions, there are individual differences in the semantic structures of emotional and preferential experiences; however, such differences in psychophysical expressions are relatively minor.

“…The absence of relevant studies of RM in extra-visual domains appears particularly puzzling in the case of touch, as there is a vast literature on tactile motion processing (Essick, 1998;Essick et al, 2010;Whitsel et al, 1986), and tactile and visual motion have recently been out-TACTILE MOTION LACKS MOMENTUM 4 lined as using highly similar canonical computations (Pack & Bensmaia, 2015). Especially in the field investigating non-veridical perceptions, crossmodal comparisons may be helpful to uncover underlying mechanisms (Christopher Bill & Teft, 1972;Helson, 1930;Sarrazin, Giraudo, & Pittenger, 2005).…”

The displacement of the final position of a moving object in the direction of the observed motion path, i.e. an overestimation, is known as Representational Momentum. It has been described both in the visual and auditory modality, and is suggested to be modality-independent.Here, we tested whether a Representational Momentum can also be demonstrated in the somatosensory domain. While the cognitive literature on Representational Momentum suggests that it can, previous work on the psychophysics of tactile motion perception would rather predict an underestimation of the perceived endpoint of a tactile stimulus. Tactile motion stimuli were applied on the left and the right dorsal forearms of 32 healthy participants, who were asked to indicate the subjectively perceived endpoint of the stimulation. Velocity and direction of the trajectory was varied. Contrary to the prediction based on the Representational Momentum literature, participants in our experiment significantly displaced the endpoint against the direction of movement (underestimation). The results are thus compatible with previous psychophysical findings on the perception of tactile motion. Further studies combining paradigms from classical psychophysics and cognitive psychology will be needed to resolve the apparently paradoxical predictions by the two literatures.

“…On average, the low frequency vibrations were rated as pleasant (rather than unpleasant), but with an average rating of 11.78 on the scale from -100 (100% unpleasant) -100 (100% pleasant), were close to neutral. This possibility could be explored in future by comparing the effect of global/local processing on the pleasantness of other tactile stimuli with a more distinct difference in pleasantness, known to be characteristically pleasant/unpleasant, such as cosmetic brushes/velcro (Essick et al, 2010).…”

Visual–tactile carry-over effects of global/local processing (attention to the whole, versus the details) have been reported under active touch conditions. We investigated whether carry-over effects of global/local processing also occur for passive touch and whether global/local processing has differential effects on affective and discriminative aspects of touch. Participants completed two tactile tasks involving pleasantness rating and discrimination of a set of tactile vibrations before and after completing a version of the Navon task that encouraged a focus on the global ( n = 30), local ( n = 30), or both ( n = 30) features of a series of visual stimuli. In line with previous research suggesting a link between global processing and positive emotion, global processing increased pleasantness ratings of high-frequency (but not low-frequency) tactile vibrations. Local processing did not improve the ability to discriminate between vibrations of different frequencies, however. There was some evidence of a tactile–visual carry-over effect; prior local processing of tactile vibrations reduced global precedence during the Navon task in the control group. We have shown carry-over effects of global versus local processing on passive touch perception. These findings provide further evidence suggesting that a common perceptual mechanism determines processing level across modalities and show for the first time that prior global processing affects the pleasantness of touch.
