  • Interactions between instrumental timbre and consumers' regulatory focus

    Tsutomu Sunaga

    Journal of Business Research   121 ( December ) 1 - 12  2020.08  [Refereed]

    　View Summary

    Although music is widely used as a sensory marketing tool and incorporated in multisensory consumer–computer interactions, the role of timbre in marketing has not been extensively discussed. This study used five experiments which demonstrate that compared with violin/flute timbres, the piano timbre fits listeners' prevention focus. This is because the piano timbre is familiar to individuals and induces feelings of security congruent with the listener's prevention orientation. When exposed to a piano (vs. violin/flute) timbre as background music in an advertisement, consumers evaluate both the advertisement and the product/service more positively when they are prevention (vs. promotion) focused or when the advertisement message is framed in a preventive (vs. promotional) way. However, the timbre's effect exists only when consumers' cognitive load is low. This research contributes to sensory marketing in theory and practice and suggests that marketing managers should avoid using obsessive sensory stimuli in virtual and augmented reality.

  • How the sound frequency of background music influences consumers’ perceptions and decision making

    Tsutomu Sunaga

    Psychology and Marketing   35 ( 4 ) 253 - 267  2018.04  [Refereed]

    　View Summary

    This study examined how music frequency affected consumers’ perception and decision making. The results of three experimental studies show that music frequency affects perceived distance between the sound source and the perceiver. Consequently, the representation of marketing message that matched (vs. mismatched) the background music's frequency enhanced consumers’ evaluative judgments. Specifically, Study 1A demonstrates that low-frequency (vs. high-frequency) music increased perceived distance. Studies 2, 3A, and 3B indicate that low-frequency (high-frequency) music matched products with abstract (concrete) representations and marketing messages signifying far (near) psychological distance. The congruency between psychological distance induced by music frequency and mental representations of products and message orientation offers a novel perspective on the notion of congruency. Moreover, Study 2 provides evidence that supports the congruency–fluency–evaluation chain (i.e., the mediating role of fluency), and Studies 3A and 3B show that the congruency has downstream effects. This study provides a theoretical contribution to the literature on the effects of music in marketing contexts by presenting convergent evidence that individuals exposed to low-frequency (high-frequency) music are inclined to construe a marketing message at a high (low) level.

  • Effects of Lightness-Location Congruency on Consumers' Purchase Decision-Making

    Tsutomu Sunaga

    Psychology & Marketing   33 ( 11 ) 934 - 950  2016.10  [Refereed]

    　View Summary

    A considerable body of psychological and neuroscientific research has demonstrated the existence of robust sensory correspondences between various features, attributes, or dimensions of experience in different sensory modalities. Despite findings indicating the importance of sensory correspondences to human information processing, research on purchase decision-making has not focused on this phenomenon sufficiently to date. The present study examines how the lightness of packaging colors, and the location of products on a display shelf interact to affect consumers’ purchase decision-making via perceived visual heaviness. As predicted, a display with light (dark) colored products positioned in the upper (lower) shelf positions increases shoppers’ perceptual fluency and facilitates their visual search, thus leading to the suggestion that “light” (“heavy”) locations are most appropriate for light (dark) colored products. Moreover, the lightness-location congruent display is shown to positively influence people’s choice behavior as well. This research also demonstrates that when consumers consider the lightness (in terms of their weight) of the products, they are more likely to choose light (vs. dark) colored products located in the upper shelf positions. These results therefore demonstrate that consumers’ purchase decision-making may be promoted by in-store environments that are designed to be congruent with their sensory correspondences.

    　View Summary

    This research is empirically showing the validity of a circulating response model on advertising effectiveness. The model proposed in this paper is unique in the following points. First, it indicates that the responses of consumers to advertising are not linear, but circulating. Another point is, it embodies the idea that attitude of consumers towards the advertisement has effects on not only one specific stage but also in various stages of cognitive responses to advertising. Furthermore, this research proposes a way which numerically expresses the effect of ripening caused by the circulating process of response to advertising.

    　View Summary

    Conducting a controlled lab experiment (Study 1) and a real-world field experiment (Study 2), this study investigated how sequential exposure to music influenced consumers’ decision-making. Study 1 demonstrated that the consumers previously exposed to higher- (vs. lower-) pitched music were more likely to perceive the subsequently presented music as being spatially descending and consequently associated the subsequent music with dark (vs. bright) paintings. Furthermore, Study 2 revealed the downstream effects of sequential exposure to music; thus, consumers exposed to the experimental music after being presented with the higher- (vs. lower-) pitched music were more likely to choose a product with dark (vs. bright) colours. The results of the present study suggest that even when individuals perceive a song’s pitch to be high, they do not necessarily associate it with bright colours. The study contributes theoretically to various areas of relevant literatures, including multisensory perception, crossmodal correspondence, sensory marketing, and music psychology, by highlighting the effects of sequential exposure to music on consumers’ crossmodal associations between musical pitch and colour brightness. The findings could be beneficial to marketers who use music as a marketing tool (e.g., store background music and advertisement music). For instance, shoppers in malls or complexes may wander from one tenant shop to another—that is, shoppers are sequentially presented with musical pieces. Considering the context effects of sequential exposure to music could promote a deeper understanding of consumers’ perceptions of—and responses to—complex auditory stimuli.

    INFORMS 2021 Annual Meeting  (Virtual)  Institute for Operations Research and the Management Sciences

    Presentation date： 2021.10

    　View Summary

    Despite most sensory information being received sequentially, little research on crossmodal correspondence has taken this context into account. Our study bridges this gap by investigating how initial exposure to relatively high-/low- frequency music affects consumers’ crossmodal associations between subsequent music and fine art paintings. The results have demonstrated that participants first presented with high- (vs. low-) frequency music are more likely to perceive the subsequent music as matching cool, dark, and abstract paintings. We uncovered that the association with “spatial descending” mediated this process.

  • Assessing Multisensory Congruence Involving Instrumental Timbre

    EMAC (European Marketing Academy) 2021 Annual Conference  (Madrid, Spain)  European Marketing Academy

    Presentation date： 2021.05

    　View Summary

    We report two studies designed to investigate the semantic differential associations that people hold with instrumental timbre. The first study examined semantic associations with instrumental timbre amongst participants from the UK, Japan, and Africa. A second study investigated the effects of matching the semantic differential congruency of auditory timbre with different material properties shown in promotional videos. The results revealed that matching semantic differential congruency enhanced both the experience of ‘feeling right’ and the participants’ emotions, leading to the video being liked more, and the product itself receiving more positive responses. We believe that the matching of unrelated auditory and visual stimuli (instrumental timbre and visually-presented materials) on the basis of their semantic differential congruency offers a novel approach to sensory marketing. This study also provides a theoretical contribution to the literature on multisensory experience design by highlighting the mediating role of the subjective experience of ‘feeling right.’

  • Music Timbre and Regulatory Fit (Competitive Papers Session)

    Sunaga, T, Zhuang, X, Meng, Y

    The 48th EMAC Annual Conference 2019  (University of Hamburg, Germany)  European Marketing Academy

    Presentation date： 2019.05

    　View Summary

    This study examined how musical timbre contributed to regulatory fit and persuasion. The results showed that piano (vs. violin/flute) associated with prevention (vs. promotion) focus (Study 1), which replicated in the marketing context as well (Study 2). Moreover, Study 3 demonstrated that when music played on the piano (violin/flute) was used in an advertisement, regulatory fit occurred among prevention- (promotion-) focused participants, meaning that the participants reported more favorable advertisement and product evaluations. The association between musical timbre and consumers’ regulatory focus offers a novel perspective on the notion of regulatory fit. The current study also provides a theoretical contribution to the sensory marketing and advertising literature by presenting convergent evidence that consumers exposed to music from different types of instruments response a marketing communication differently.

    　View Summary

    This study provides a theoretical contribution to the literature on the effects of music in marketing contexts by investigating whether and how frequency of background music affects consumers’ perceptions and their subsequent decision-making. The results of four experimental studies show that (1) low-frequency (vs. high-frequency) music increases perceived distance, and (2) low- (high) frequency background music enhances consumers’ evaluative responses to a marketing communication when the representation of the target product was abstract (concrete). The results support the view that individuals exposed to low-frequency (high-frequency) music are inclined to construe the marketing message at a high (low) level.

    行動経済学、行動意思決定論などの研究領域において、人の判断や行動に影響するバイアスに関する研究が活発に行われてきた。これらの研究の多くは、人が受け取った情報をもとにして判断や意思決定を行うという認知過程で発生する、認知バイアスに焦点を当ててきた。これに対して本研究では、人が刺激に接し、それを知覚する過程で生じる知覚バイアスを扱う。例えば、同じものを飲んでも、グラスの硬さや触感によって味覚が変わるという現象は、知覚過程で生じるバイアスである。消費者行動における知覚バイアスの影響を体系的に整理するために、本研究ではラボ実験、フィール実験などを用いて、頑健な研究成果を獲得することを目指している。

    本研究では芸術家の創作プロセスに光を当てることにより、芸術家特有の創作視点や創作プロセスを明らかにする。そうした芸術家特有の志向を「アート志向」と呼ぶ。２年目については、以下の研究を進めることができた。
    まず、１年目に引き続き、アートや製品開発に関する文献調査に取り組むことで、既存研究の整理を進めている。今後、これらの文献については、先行研究を整理したうえで、レビュー論文などとして成果発表をする予定である。
    次に、アートを職業としている人物に対して、１年目に実施した６名のヒアリング調査に続き、さらに２名のヒアリングを実施した。今回のテーマである「アート志向の解明による製品開発研究のブレークスルー」に基づき、まずアート志向の実態を明らかにしなければならない。そのため、職業としてアートに取り組んでいる人々が、どのようなマインドで自らの作品を生み出しているのかについての考察から着手した。そこでの結果は現在整理段階にあるが、作品の着想、作品の制作プロセスなどにおいて、私たちがビジネスの分野でこれまで接してきた志向とは明らかに異なる志向が見いだされつつある。
    また、アートと音楽の結びつきにも注目し、特に音楽を聴いた消費者が、その後に見たアート作品やアートが盛り込まれた製品に対して、どのような知覚や評価を行うかについて検証した。以上の調査については、１年目に国内において実施したパイロット調査の結果に基づき、研究の一般化可能性を高めるため、同様の調査を海外にて実施した。また以上の結果は２０２１年１０月に海外にて学会報告を行った。

    　View Summary

    Based on a hypothesis that consumers’ evaluation and choice behavior becomes more abstract when psychological distance (time, space, degree of intimacy etc.) is large, we investigated the determining factors of customer satisfaction across various purchase situations and obtained supportive results. Also, we have made some progress in measuring abstractness of consumers’ thinking.
