Passive visual behavior modifiers and consumer psychophysiology online.

Abstract

Through an examination of the electroencephalography (EEG) data collected from 27 university students, this study examined the efficacy of three known passive visual behavior modifiers -- color, layout, and motion -- in an e-commerce environment. These three variables have significant scholarly support in the context of traditional media, but their effect online is still largely unsubstantiated. Using EEG readings taken from regions of interest Fp1 and Fp2, the researcher attempted to measure and compare sustained evoked response upon exposure to six fictitious e-commerce web pages, each exhibiting a different passive visual behavior modifier. It was hypothesized that (H1) a product in a subtle state of motion, (H2) a greater proportion of image to text, and (H3) a color system with a dominant wavelength of approximately 650nm would evoke higher average levels of amplitude (μV) and frequency (Hz) in the ventromedial prefrontal cortex compared to stimuli exhibiting inverse properties: a static product image, a greater proportion of text to image, and a color system with a dominant wavelength of approximately 490nm. The biofeedback measurement was supplemented by a qualitative interview. Participant responses were analyzed for key words, phrases, and trends related to consumer attitude and product preference. While no significant differences were found between the visual stimuli, this study provides insight, limitations, and direction for future psychophysiological research relating to e-commerce.--Abstract.
