Psychophysiologically Evaluated Visuo-Tactile Affection using Printed Fabrics

Abstract

The present study compared to the three perceptional conditions of tactile affection−tactile tactility, visual tactility, and visuo-tactile affections−using psychological evaluation and psychophysiological methods. A comparative study was performed to fine out the differences of psychological and psychophysiological tactile perception according to the conditions of tactile perception. Furthermore, it also aims to find out the important fabric factor for tactile affection. Through the previous study, we found the fabric factors which influenced in tactile affection of fabrics: weave construction and fabric pattern. Total of six printed fabrics were developed by DTP method on naturally colored organic cotton fabrics as stimuli. Thirty participants were placed by randomized incomplete block design for the experiment. For measuring psychological affection, questionnaire was developed using a 9 points semantic differential scale. Electroencephalogram(EEG) was measured as a CNS response and electrocardiogram(ECG), skin conductance level(SCL), and photoplethysmography(PPG) were quantified as ANS responses. According to the results, perceptional condition had little effect on psychological and psychophysiological tactile perception. Significant effects on perceptional condition showed only on “showy-plain” affection and SCL response. Mostly, weave construction was more important fabric factor to perceive tactile affection than fabric pattern. However, the importance of fabric pattern also observed through the interaction effects.
