This study examined the effects of antismoking ads on Korean adult male smokers. An experiment was conducted to explore how message framing and visual-fear appeals embedded in antismoking ads may influence ad-evoked fear, threat appraisals, and intention to quit smoking. Results showed that (a) antismoking ad exposure increased ad-evoked fear and cessation intention; (b) optimistic bias was stronger when the visual-fear appeal was absent in antismoking ads; and
Background/Aims: No studies have clearly demonstrated how sex hormones are involved in the observed gender difference in growth and plasma cholesterol levels in animals fed hypercholesterolemic diets. This study was conducted to determine the effects of gender, gonadectomy (GNX), and sex hormones on growth, plasma cholesterol and cortisol levels in Sprague-Dawley rats. Methods: In the first of two experiments, equal numbers of male and female 4-week-old rats were divided into three groups: sham-operated control, GNX, or GNX + 17α-methyltestosterone (MT). The rats were fed a hypercholesterolemic diet for 4 weeks. In a second experiment, 24 GNX females were equally divided into three groups: control, 17β-estradiol (E2), or MT. These rats were fed a normocholesterolemic diet for 3 weeks. Results: The average total plasma cholesterol level in female rats was twice that in male rats. MT administration to GNX male and GNX female rats decreased plasma cholesterol levels by 23 and 45%, respectively. Weekly intramuscular injection of E2 markedly suppressed growth while increasing plasma cortisol levels in GNX female rats. Conclusion: Testosterone decreases plasma cholesterol levels in rats fed a hypercholesterolemic diet and E2 suppresses growth of rats, inducing the secretion of hormones that increase with stress.
This study investigates age and cultural differences in the negative effects of senders’ wearing masks on receivers’ readabilities of senders’ facially expressed emotions in interpersonal interactions. An online experiment was thus conducted with Koreans and Americans aged over 20 years. Based on sampling quotas by nationality, age group and gender, Korean (n = 240) and American (n = 273) participants were recruited from panel members of a Korean research company and Amazon’s Mechanical Turk via email and the website, respectively. The participants played receiver roles to infer senders’ facially expressed emotions presented in photos in the experiment. They judged emotions facially expressed by the senders without masks and with masks are shown in photos. The results revealed that the senders’ wearing masks reduced the readabilities of the senders’ facially expressed anger among participants aged 30–49 years more than among participants aged 20–29 years. The senders’ wearing masks decreased the readabilities of the senders’ facially expressed fear for participants in their 50’s more than for participants in their 20’s. When the senders wore masks, the readabilities of the senders’ facially expressed happiness dropped among participants aged over 60 years more than among participants aged 20–49 years. When senders wore masks, American participants’ readabilities of disgust, fear, sadness and happiness expressed in the senders’ faces declined more than Korean participants’ readabilities of those emotions. The implications and limitations of these findings are discussed.
The use of a celebrity endorser who is well recognized and favorably evaluated by the target viewers is a common strategy used by advertisers to increase the persuasiveness of an advertisement. Yet, at the same time, being skeptical of the claim being made by the celebrity endorser is the typical response of the viewers to such persuasion attempts. The present research examines how these effects potentially counterbalance each other as viewers evaluate the advertised brand in a low‐involvement setting. The results show that the degree of ad skepticism and the relative allocation of attentional resources to celebrity and brand elements in advertisements determine how preference for a celebrity endorser is transferred to the advertised brand. The findings provide a more complete understanding of the psychological mechanisms by which celebrity preference influences brand attitude change than has previously been available. They indicate that ad skepticism may be the missing link in understanding the effectiveness of celebrity‐endorsed advertising.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
