The role of need for cognition in consumers' mental imagery: a study of retail brand's Instagram

Abstract

PurposeDrawn from the concepts of processing fluency and mental imagery, the present study aims to fill the void by developing the mechanism underlying consumers' cognitive processing of visually appealing digital content in social media (i.e. Instagram) of retail brands.Design/methodology/approachData were gathered using a web-based survey method with consumers residing in the USA (N = 328). Structural equation modelling (SEM) was employed to investigate the proposed hypotheses. In addition, measurement invariance and multigroup analyses were conducted to test the moderation effect of need for cognition (NFC).FindingsThe results supported the pivotal role of mental imagery when consumers process visual messages in the context of a retail brand's Instagram. Both comprehension fluency and imagery fluency positively influence mental imagery, which in turn cultivates positive attitude towards the brand. The mediating role of mental imagery is confirmed. Furthermore, individuals' NFC interacts with imagery fluency but not with comprehension fluency such that high NFC strengthens the effect of imagery fluency on mental imagery. That is, when high-NFC consumers process information on Instagram, their perceptions of ease of generating imagery likely evoke visual representation of the brand's messages on Instagram in their minds.Practical implicationsThis research provides feasible ways for brands to increase the effectiveness of digital marketing communications in social media (e.g. optimising of the contextual features of visual information and employing interactive features such as filters of social media to enhance processing fluency).Originality/valueWithin the context of digital retailing, this study provides a new perspective of consumers' imagery processing to investigate the effectiveness of visual-focussed messages.
