This research was conducted to examine repeat online grocery shoppers behavior based on the S-O-R paradigm (Mehrabian and Russell, 1974) for a five year time frame. Not considering any artificial intelligence, generally in the online shopping environment, the image of the store is communicated through their product and site offerings as well as their user-friendliness of the website. Childers et al. (2001) discussed hedonic aspects of an online store environment such as web atmospherics. Furthermore, with a growing importance of atmospheric cues, researchers are now paying attention to consumer characteristics (Moriuchi and Takahashi, 2018). In general, the results show that atmospherics has an impact on pleasure and satisfaction. Both pleasure and satisfaction have an effect on loyalty. Trust served as a moderator between O-R and was significant. Comparing between the 2012 and 2016 data, results show that satisfaction consumers in the 2012 sample did not see an impact on satisfaction on loyalty, and trust was not a moderating factor on satisfaction and loyalty. However, all the other hypothesized relationships were significant for the 2016 sample. The results suggest a couple of practical implications. First, the ease of navigation are important in pleasing and satisfying online grocery shoppers. Marketing practitioners should focus on how to make the overall website easily navigable. This could include having clear display of the products, reviewing of product descriptions and ease of going back to the main menu after adding items to cart. Second, marketing practitioners should focus their attention on the variety of products available and the quality of products available such as pleasure.

As information and communication technologies (ICTs) become more advanced, consumers are able to experience retailing activities such as searching for products and services in online retail shops and for Internet-exclusive branded contents. Specifically, fashion retailers are facing the need to develop more novel experiential design than one another to maximize customers’ experience in Internet websites and secure sustainable competency. Confirming methods of organic integration of experiential and visual features of both online and mobile channels is an important aspect of the study of extended consumers’ interfaces of retail channels. Mehrabian and Russell’s stimulusorganism- response (S-O-R) paradigm and Sugiyama and Andree’s attention, interest, search, action, and share (AISAS) model were used for this research. Specifically, the present study considered the effect of e-commerce website features on consumers’ emotional reactions (pleasure and arousal) and the consequent impact on online consumer behaviors (search, action, and share). Hence, plus the self-reported survey methods, each subject’s psychophysiological indicators (i.e., pleasure and arousal) were measured to obtain more objective and reliable data and to redeem the results of the self-reported survey. Findings revealed the implications of the e-commerce website feature by comprehending the S-O-R paradigm and AISAS model and extending the understanding of the role of variables associated with comprehended frameworks based on psychophysiological data.
