We investigate consumer preference interactions in visual choice-based conjoint analysis, where the conjoint attributes are parameters that define shapes shown to the respondent as images. Interaction effects are present when preference for the level of one attribute is dependent on the level of another attribute. When interaction effects are negligible, a main-effects fractional factorial experimental design can be used to reduce data requirements and survey cost. This is particularly important when the presence of many parameters or levels makes full factorial designs intractable. However, if interaction effects are relevant, a main-effects design creates biased estimates and potentially misleading conclusions. Most conjoint studies assume interaction effects are negligible; however, interactions may play a larger role for shape parameters than for other types of attributes. We conduct preliminary tests on this assumption in three visual conjoint studies. The results suggest that interactions can be either negligible or dominant in visual conjoint, depending on both consumer preferences and shape parameterization. When interactions are anticipated, it is possible in some cases to re-parameterize the shape such that interactions in the new space are negligible. Generally, we suggest that randomized designs are better than fractional factorial designs at avoiding bias due to the presence of interactions and/or the organization of profiles into choice sets.

In conjoint analysis, interaction effects characterize how preference for the level of one product attribute is dependent on the level of another attribute. When interaction effects are negligible, a main effects fractional factorial experimental design can be used to reduce data requirements and survey cost. This is particularly important when the presence of many parameters or levels makes full factorial designs intractable. However, if interaction effects are relevant, main effects design can create biased estimates and lead to erroneous conclusions. This work investigates consumer preference interactions in the nontraditional context of visual choice-based conjoint analysis, where the conjoint attributes are parameters that define a product's shape. Although many conjoint studies assume interaction effects to be negligible, they may play a larger role for shape parameters. The role of interaction effects is explored in two visual conjoint case studies. The results suggest that interactions can be either negligible or dominant in visual conjoint, depending on consumer preferences. Generally, we suggest using randomized designs to avoid any bias resulting from the presence of interaction effects.

Purpose The relationship between brand personality and consumer personality has become a researched issue in recent years. It is viewed that marketers start the dialogue with consumers through personality route by building brand personality in line with consumers’ own personality traits. Moreover, in the midst of stiff competition, role of corporate personality, as a component of corporate identity, has been considered instrumental behind the success of the organization. As a result, there might be a possibility that other than his/her own personality traits, a consumer’s brand preference may be influenced by both brand personality and corporate personality of the said brand marketer. So, the predictive roles of individual personality, brand personality and corporate personality on consumer brand preference formation need to be empirically investigated so that the same may be addressed strategically. However, as per knowledge of the researcher, no empirical study has been made to investigate the predictive role of consumer personality, brand personality and corporate personality on brand preference. In this back drop, to the best of our knowledge, this study is the first attempt to fill this research gap by investigating firstly, the direct effects of individual personality of consumer, brand personality and corporate personality on consumer brand preference and secondly the impact of interaction effects of those variables on brand preference in the context of the emerging economies. Design/methodology/approach This study includes Indian four-wheeler passenger car market as the focal point of the study. As the product category is predominantly linked with symbolic benefits to the consumers, this target segment may be motivated to express their personality through the brands they prefer. As a result it may be an appropriate sector to study the influence of individual, brand and corporate personality behind brand preference. In this study, we have used an anonymous self-administered structured questionnaire. Part A captured respondent’s brand preference. Part B used The Big Five Model personality scale. Part C used the ‘Brand Personality Scale’ proposed by Aaker (1997) as a measure of brand personality. Part D comprised ‘Corporate Personality Scale’ developed by Davies et al. (2001). Part E recorded demographic data, including age, income, educational qualification and occupation. For Part B, C and D, Respondents were asked to rate each of the dimensions, using a five-point Likert scale, ranging from 5=Most descriptive to 1=Least Descriptive. The validity of the theoretical model is tested through Confirmatory Factor Analysis (CFA). In the first stage, main effects of the proposed model are tested. In the next stage, we have tested interaction effects of constructs on band preference. To test the hypotheses multiple regression method has been used. Findings The result of main effects shows that individual and brand personality has significant impact on brand preference for the considered brand by the consumers. This implies that at the time of brand preference, consumers give due importance to individual personality and personality of the considered brand of SUV. A strong and clear brand personality indicates a favorable view about the brand. Further, the result shows at the time of buying decision, personalities of both product and corporate brand are influencing their preferences. Here, consumers might be making strong association between corporate and brand personalities. In addition, interaction effects among individual, brand and corporate personality are also significant. One may view from the result that consumers do not encourage compartmentalize thinking at the time of brand choice. In place of considering his/her own personality and brand and corporate personality as a standalone entity, they think in totality and interaction effects have significant influence on their brand preference. Research limitations/implications The paper has mentioned limitations: the restriction on selecting industry, company and brand, the restraint of sampling coverage and lack of generalization of the study findings. The implications should be interpreted with care. In this study we have not compared different brands from same industry or brands from different industries; there is a scope to do so. Moreover, this study considers results from one national context and, consequently, cross-national study may be conducted to extend the validity of the findings. Practical implications The findings from this study may enlighten brand marketers about the degree of influence of brand personality, corporate personality, and consumer personality on brand preference. This study advocates interaction effects of individual, brand and corporate on consumer brand preference. From this study perspective, we may say, brand personality and corporate personality provide significant opportunity for creation of uniqueness and have the potential to significantly influence brand preference. Originality/value This paper makes two contributions to the brand management literature. First, it provides new empirical evidence of the positive main effect of individual and brand personality on brand preference. Second, this paper first investigates interaction effects of individual personality, brand personality and corporate personality on brand preference. This is a very unique contribution of the paper. The results provide new insights for academic and practitioners into the relationship among individual personality, brand personality and corporate personality. This study is the first attempt to fill this research gap by investigating the impact of consumer personality, brand personality and corporate personality on brand preference.

Some consumer preference studies show that red is the most popular flower color. Most data analyses were univariate. Conjoint analysis allows simultaneous determination of attribute preferences without all alternatives being shown. Our purpose was to determine consumer preferences for geranium flower color, leaf variegation, and price simultaneously using conjoint analysis. Two-hundred and four consumers shopping at two Montgomery, Ala., garden centers in Apr. 1993 rated 25 composite geranium photographs. A lavender geranium, `Danielle', with green and white leaf variegation priced at $1.39 was most preferred. Flower color was most important in the purchase decision, followed by price. Leaf variegation was a minor consideration in the purchase decision.

This article examined the antecedents of a positive wellness service experience by identifying factors leading to customers’ positive wellness service experience. This study proposes that servicescape has a positive relationship with the service experience, and that servicescape may strengthen the effects of emotion and trust. The research hypotheses were tested with data collected directly from customers of a spa located in the Midwestern United States. A multiple regression analysis was conducted to estimate how emotion, trust, and servicescape affect customers’ evaluations of spa experiences. An estimation was carried out on the interaction effects between servicescape, emotion and trust. The results indicate that the main effects of servicescape, emotion and trust, were significant, while the interaction effects did not prove to be significant. Trust has the biggest effect on customers’ wellness experience followed by emotion and servicescape. Prior research has not simultaneously addressed the role of servicescape, emotion and trust and their subsequent influence on customers’ emotional evaluation of service experience. This study therefore provides valuable insight to extend present understanding of the simultaneous role of these factors as effective predictors of the evaluation of service experience.
