This research investigated the effects of para-social interaction (PSI) in online and traditional celebrity endorsements. The data was collected by distributing questionnaire sets. And covariance structural equation modeling was used to analyze the model. The findings showed that para-social interaction is the moderator variable in the online celebrity endorsement effect.

The economic harm and survival fear caused by environmental conflicts are most likely to become the psychological lever to drive individuals to adopt environmentally friendly behaviours. From the perspective of environmental conflict, this paper will explore the transmission mechanism of environmental conflict on individuals’ pro-environmental behaviour through three experiments.

This study examines how brand-influencer, influencer-users, and user-brand congruences affect perceived fantasy about the influencer and closeness toward the brand when an Instagram ad is endorsed by celebrity (vs. non-celebrity) influencers. The study employed a between-subject online experiment by manipulating an advertisement endorsed by a celebrity and a non-celebrity influencer. The results suggest that congruence between brand-influencer matters in building effective relationships.

The rise of social media has brought the existence of “foodie” and “food bloggers” in the culinary business. The word “foodie” refers to those who highly favor and engage with food and spend a substantial amount of time collecting culinary experiences and visiting famous restaurants, while a food blogger is an individual or a foodie who uses a communication platform to share recipes and passion for food through reviews based on his or her experience. Culinary businesses use food bloggers to help promote their products and encourage consumers to try their products, which are believed to be effective as the viewers or the followers tend to take their recommendations.

가상공간의 활성화에 따라 아바타와 같이 사람을 대신하는 대리인(agent)의 사용이 활성화되었으나, 인공물이 사람 과 유사해질수록 불편함을 느끼는 언캐니밸리(uncanny valley) 현상이 장애물로 작용하고 있다. 본 연구에서는 연예인 에 기반을 둔 아바타에서 느껴지는 언캐니밸리 현상을 확인하고자 하였다. 연예인 및 일반인의 사진과 그 사진을 기반 으로 제작된 아바타에서 눈 크기를 조절하여 비전형성 정도를 조작하였고, 이에 따른 언캐니밸리 현상의 강도를 측정하 였다. 그 결과, 사진과 아바타 모두에서 연예인 얼굴에 대한 언캐니밸리 현상이 더 강하게 나타났다. 이는 친숙한 얼굴 에 대해서 더 강한 얼굴 표상이 형성되어 얼굴 변화에 대해 더 쉽게 탐지한다는 기존의 발견들과 일치한다. 한편 사진 자극에 대해서는 기존의 연구에서처럼 비전형성 정도가 높아질수록 더 높은 언캐니밸리 현상이 발견되었으나, 아바타 자극에 대해서는 비전형성 정도에 따른 효과가 발견되지 않았다. 이는 만화의 등장인물에서 얼굴의 특징이 과장되어 커지거나 작아지는 경향 때문에 아바타에서 허용할 수 있는 비전형성 정도가 크기 때문으로 판단된다. 이와 같은 결과 는 최근 연예인 아바타를 사용한 가상공간의 서비스에서 언캐니밸리 현상을 줄이기 위한 노력이 필요함을 시사한다.

This study employed the social comparison theory, brand signally theory and the theory of planned behaviour (TPB) to examine the extent to which attributes of a celebrity endorsing a brand and brand values impact on young adults’ cosmetics brand attitude and purchase intention. Data was collected from 301 young adult South Africans. Structural equation modelling results revealed that cosmetics brand attitude was influenced by celebrity attractiveness, credibility, celebrity product expertise and the symbolic brand value enjoyed from the brand. The brand attitude in turn predicted purchase intention.

The purpose of this research is to explore the factors that affect a celebrity’s perceived authenticity on social media sites. In total, 653 Taiwanese consumers were recruited to examine the proposed model. The findings generally support our model. The theoretical and managerial implications of this study are discussed.

The aims of this study are to understand the influence of celebrity endorsement on consumers’ word-of-mouth and decision behavior, that is: (i) understand the influence of the number of followers of the celebrity and the positive/negative valence of the messages conveyed by them in the intention to buy and their intention to generate eWoM; (ii) analyzing how the behavior of a celebrity (antisocial vs. pro-social) may affect the perception of its credibility, the intention of the consumers to relate to the celebrity in the social networks and the social identification with it; (iii) understand the impact of celebrity messages on brands and products present in social networks. To achieve this goal a quantitative methodology for the development of research was adopted, selecting the application of a survey as the information collection instrument. The sample is selected by convenience sampling method, collecting 241 responses, 122 females and 119 males. Findings show: (i) concerning the intention to purchase, female seem to be more influenced by the opinions and recommendations of celebrities, while male tend to be more likely to generate e-word-of-mouth into their contact network through social media. (ii) Regarding to antisocial versus prosocial type of celebrity, celebrities with a prosocial behavior seems to have a greater influence for both genders in the way they identify with celebrity and their willingness to relate to them. (iii) Female tends to feel higher purchase intention when exposed to an endorsement, where celebrity promotes a brand or product through its Instagram account.
