The aim of this study is to conduct the empirical tests on consumer's emotional responses of product design and the relationship between emotion and consumer's attitudinal loyalty to identify if there exists potential relationship links between these two factors together by following certain regulation. This study also seeks to compare Brand Loyalty of Apple products across two different cultures - China and US to see if there are any differences regarding their brand loyalty construction and expression. The emotional responses on product design were also studied in order to reveal potential emotional design issues between the two different cultures. Results of this study show that: (1) Brand loyalty strengthens a consumer's emotion bond with a targeted brand through its product carrier. Emotion is seen as a predictor for brand loyalty based on consumer proportionality and conformity of expression. (2) Cognitive experience is not necessary nor a sufficient condition to build brand loyalty. Emotion and culture will be crucial in constructing brand loyalty without cognition. Cultural differences will affect brand loyalty, especially regarding attitudinal loyalty. (3) Different cultures share different ways of emotional expression. Based on the scope, limitations, and results of this research, Chinese consumers appear to be more sensitive in their emotional feelings of the iPad's design than American consumers.
