廣告中動機訴求與說服路徑設計對廣告效果之影響 / The Advertising Effect of Motivate Appeal and ELM Route Design

陳佩珊, Chen, Pei-Shan Unknown Date (has links)
「推敲可能性模式」中提到的「動機」因素,指的是個人產生的動機強弱;但若從心理學的觀點出發,我們可在動機心理學的相關文獻中發現:動機的種類所帶來的不同程度影響,則是非常重要的。因此,本研究希望把「推敲可能性模式」中的「動機」因素做延伸、補充,探討不同種類的動機因素如何影響廣告效果。期待能為「推敲可能性模式」帶來嶄新的討論空間。 以往在學術研究中,廣告效果的相關研究多從產品類別、廣告音樂、一般廣告訴求(理性訴求、感性訴求、性訴求、幽默訴求或恐懼訴求等)或消費者的人格特質與涉入程度等來探究廣告效果。事實上研究者認為:廣告效果更應與廣告訊息內容的呈現息息相關。廣告中呈現不同的需求或慾望刺激,是否使得廣告的說服效果產生差異?這樣的問題意識正好可以與上述關於「推敲可能性模式」的討論相呼應,研究者期望藉由這樣初探性的實證研究,瞭解廣告訊息中隱含的動機需求對廣告說服效果的影響。 從Maslow提出的觀點,我們可以說,各種需求之間,有先後順序與高低層次之分別,人類與生俱來的匱乏需求必須先被滿足,但Maslow提醒人們不要過於拘泥看待每一需求的順序;況且,這個社會中有許多人,他們絕大多數的匱乏需求大多得到了滿足(莊耀嘉,1990);Maslow更指出,隨著需求階層的上升,受到滿足的人數百分比是逐漸減少的(彭運石,2001)。以台灣目前的物質水準來說,大多數的人多半是處在匱乏需求已獲得某種程度的滿足、正轉而追求更高層次之理想實現的情況。 依此推論,多數人在面對「匱乏訴求」取向的廣告訊息時,符合「資訊處理節省原理」(Haines,1974)的論點,消費者產生的深思可能性較低;在面對「存在訴求」取向的廣告訊息時,則符合「認知反應理論」之觀點,所產生的深思可能性較高。又根據「推敲可能性模式」(ELM):當深思可能性高,中央路徑的說服特別有效;當深思可能性低時,邊陲路徑的說服效果較佳。因此,本研究衍生推論:消費者面對「生理層面匱乏訴求」的訊息時,因廣告刺激的是匱乏需求,在深思可能性較低的情況下,採用邊陲路徑說服方式之效果較佳。消費者面對「心理層面匱乏訴求」的訊息,因廣告刺激的是匱乏需求,同樣也是深思可能性較低的情況下,採用邊陲路徑說服方式之效果也較佳。相較之下,消費者面對「存在訴求」取向的訊息時,深思可能性較高,若配合中央路徑的說服方式,應有較佳效果。 研究結果分為兩大部分:主要自變項與依變項之因果關係假設檢驗、動機訴求類別與資訊路徑之關係討論。本研究主要探討動機訴求之廣告類別,在不同路徑之設計之下,所導致的廣告效果差異。統計方法上主要應用單因子變異數分析(ANOVA)與簡單線性迴歸分析(Simple Linear Regression)。檢定研究中主要自變項:中央、邊陲路徑訊息設計方式,在五個依變項:整體注意力、對主要訊息的理解度、對主要訊息的記憶度、對廣告的態度及對品牌的態度等的差異情況。

線上廣告訴求與認知需求對消費者購買決策的影響 / Effects of Online Advertising Appeal and Cognitive Need on Consumer’s Purchase Decision

張杰 Unknown Date (has links)
現今社群媒體已經是人們生活的一大部分,而網路提供了更容易與消費者接觸的平台給廠商呈現其廣告訴求,廣告訴求是一種策略,利用其所呈現的訴求說服消費者作出購買決策,或是改變消費者對於品牌的態度。本研究探討廣告內容的訊息訴求對於消費者購買決策的影響,並利用推敲可能性模型分析消費者的決策路徑。 因為先前針對推敲可能性模型的決策路徑主要都是以推論為主,本研究設計了一個測量中央及邊陲路徑的問卷,藉此了解受測者實際感受到的決策路徑。而整體的問卷透過一個網路實驗收集資料,結果發現廣告訴求對思考路徑有顯著的關係,理性的廣告訴求會使消費者傾向於使用中央路徑;感性的廣告訴求則會使消費者傾向於使用邊陲路徑,而認知需求會對這個關係有交互作用的影響。同時也發現思考路徑對於購買意願會有顯著影響,不同的產品類型會對於這個關係有交互作用的影響。 / Social media and the Internet are inseparable elements of modern human life. Online advertising becomes a popular method for vendors to access their consumers. Advertising appeals are important in attracting consumers’ attention of products and services. In this study, we investigate the effect of online advertising appeals on consumer’s purchase decision using the Elaboration Likelihood Model (ELM) that proposes a central-peripheral dual-route persuasion mechanism. We designed an instrument to measure the perceived route in decision processes and applied it in an online experiment to examine how different appeals affect the central and peripheral routes in consumers’ decision processes. The results indicate that advertising appeals have significant effect on decision routes. Cognitive needs are found to have interaction effects. Decision through different routes also have significant effect on consumers’ decision, while product types have moderation effects.

以推敲可能性理論探討軟體專案承諾升級 / Escalation of Commitment in Software Projects: An Elaboration Likelihood Model Perspective

張菀庭, Chang, Wan-Ting Unknown Date (has links)
軟體專案承諾升級現象發生時,可能會造成更多資源成本的投入,若投入更多的資源,而專案依然失敗,則會造成更多的浪費,是企業界最不希望看到的情形。本研究利用推敲可能性理論探討此現象,了解不同的說服方式如何影響受測者的決策過程。根據遇到專案的狀況,依照訊息訴求分成理性訴求與感性訴求的敘述方式,加入框架效應 (正向/負向) 以及訊息強度 (低/中/高) 兩變數,以自我責任作為調節變項進行探討,研究在不同情況敘述下,決策制定者接收專案訊息描述後其決策過程中的推敲可能性,以及推敲可能性與決策之間的關係。 研究發現如下: 1. 單一效果影響下,訊息強度中比起其他兩個強度較容易引起訊息接收者運用中央路徑思考。 2. 訊息訴求、訊息框架以及訊息強度會交互影響受測者推敲可能性,在正向框架下,訊息訴求與訊息強度對訊息接收者運用中央路徑做決策有顯著的交互作用。 3. 在訊息強度中與強的情況下訊息訴求與訊息框架對訊息接收者運用中央路徑做決策有顯著的交互作用。 4. 在感性訴求、正向框架與訊息強度強的訊息描述下,訊息接收者運用中央路徑思考時,較不容易做出承諾升級的決定。 5. 在自我責任調節下,則是感性訴求、負向框架與訊息強度弱的訊息描述,會引起訊息接收者運用中央路徑思考時,較不容易做出專案繼續的決策。 / Escalation of commitment is common in software project development. There are a few theories that have been used to explain this behavior, including the framing effect and self-responsibility. This study investigates the issue from the dual-path elaboration likelihood model (ELM) to examine how different persuasion routes may play roles in the decision process. An experiment was designed to study the effect of different descriptions of project status that may lead to different decision routes (central versus peripheral routes). The experiment design includes message appealing (rational vs emotional appealing), message strength (strong, medium and weak), and framing (positive vs. negative) as main variables and the responsibility as a moderator. The subject was asked to decide whether s/he would continue the project under a given scenario. Our results includes the following: 1. Message appealing, message framing, and message strength have significant interaction effect on the subject’s decision routes; 2. In positive framing, message appealing and strength has significant interaction effect on the use of the central route; 3. When message strength is medium or strong, message appealing and framing has significant interaction effect on the use of the central route; 4. Regarding to decision escalation, the likelihood of escalation is lower when the decision route is central (thinking) under the emotional appealing, positive framing, and strong message; 5. The likelihood of escalation is lower when the decision route is central under the emotional appealing, negative framing, and weak message description.

以推敲可能性模式探討影響評論幫助性之因素 / Factors Affecting Review Helpfulness : An Elaboration Likelihood Model Perspective

熊耿得, Hsiung, Keng-Te Unknown Date (has links)
在電子商務中,評論會影響消費者的購買決策,透過評論幫助性可以篩選出關鍵的評論,以利消費者進行決策。本研究以推敲可能性模式作為研究架構,透過文字探勘挖掘評論的文本特性來探討影響幫助性之要素,中央線索除了評論長度與可讀性外,利用LDA主題模型衡量評論主題廣度;周邊線索則是透過環狀情緒模型進行情感分析,並透過評論者排名來衡量來源可信度,利用亞馬遜商店中的資料進行驗證分析。結果發現,消費者在判斷評論幫助性時,會參考中央以及周邊線索。具備高論點品質的中央線索將有效提升評論幫助性;周邊線索整體而言,證實了社會中存在負向偏誤,具備喚起度的負向情感較容易提升評論幫助性,而評論是否被認為有幫助確實會受到評論者的排名所影響。進階分析結果顯示,周邊的情感效果會受到評論者排名高低的影響,前段評論者應保持中立避免帶有個人情緒;中段評論者的評論幫助性會隨著情緒喚起度而增加;後段評論者則需要增加自身的負向情感,才能夠對於評論幫助性有正向影響。 / Online reviews are important factors in consumers’ purchase decision. The helpfulness of reviews allows consumers to quickly identify useful reviews. The purpose of this study is to investigate the nature of online reviews that affect their helpfulness through the lens of the elaboration likelihood model. For the central cues, we adopt latent dirichlet allocation to measure review breadth in addition to review length and review readability. For the peripheral cues, we use the sentiment analysis based on the circumplex model to catch the emotion effect and use the ranking of the reviewers to measure the source credibility. We used a dataset collected from Amazon.com to evaluate our model. The result suggests that consumers focus both central and peripheral cues when they read reviews. Consumers care about the length, breadth and readability of reviews associated with the central route, and the emotional effects associated with the peripheral route. In the advanced research, we split our sample into 3 groups by their ranking of the reviewers. We found that the top reviewers should keep neutral and avoid personal feelings to make their reviews more helpful; the middle reviewers can use more arousal words to improve their review helpfulness; the bottom reviewers must increase their emotional valence strength, especially the negative emotion to higher the perceived review helpfulness.
