Traditional strategies for determining whether a reinforcer schedule enhances the occurrence of an activity are reviewed and critically evaluated. A basic assumption underlying these strategies is that it is possible to isolate the effect of reinforcer intermittency on schedule induction. It is concluded that this is not, in fact, possible. An alternative approach is proposed that emphasizes the inductive effects of the reinforcer schedule as a unit and the effects of particular aspects of the reinforcer schedule (e.g., interreinforcer interval, repetition of the reinforcer, reinforcer magnitude). 相似文献

Smokers and nonsmokers were compared on three aspects of academic achievement. Although exactly the same percentage of smokers
and nonsmokers passed the first-year university examination, smokers obtained significantly higher marks. Similarly, smokers
achieved significantly higher marks in their final year examinations in comparison with nonsmokers. Finally, a comparison
of the tutorial essay marks of the smokers and nonsmokers again showed that smokers obtained significantly higher marks than
nonsmokers. These data are consistent with the idea that ambitious students adopt smoking in the belief that it will help
them study and sustain concentration. 相似文献

We test the hypothesis that COVID-19 vaccine hesitancy is attributable to distrustful complacency—an interactive combination of low concern and low trust. Across two studies, 9,695 respondents from different parts of Britain reported their level of concern about COVID-19, trust in the UK government, and intention to accept or refuse the vaccine. Multilevel regression analysis, controlling for geographic area and relevant demographics, confirmed the predicted interactive effect of concern and trust. Across studies, respondents with both low trust and low concern were 10%–22% more vaccine hesitant than respondents with either high trust or high concern, and 26%–29% more hesitant than respondents with both high trust and high concern. Results hold equally among White, Black, and Muslim respondents, consistent with the view that regardless of mean-level differences, a common process underlies vaccine hesitancy, underlining the importance of tackling distrustful complacency both generally and specifically among unvaccinated individuals and populations. 相似文献

Although abortion in China has been legalized for several decades, it is still controversial and the woman and man involved are at risk of being stigmatized. The current research replicated two studies conducted in Italy by investigating how the abortion decision of the woman and man influence received moral outrage, dehumanization, and perceptions of female professional competence. Study 1, which only included female participants, found higher moral outrage toward a woman having an abortion when the pregnancy was depicted as referring to a “child” (vs. “foetus”), and higher dehumanization of the woman in terms of human nature. Study 2, which included both male and female participants, and clarified responsibility for the abortion decision with respect to the woman and the man, revealed higher moral outrage and a reduction in the attribution of human uniqueness to the man, and of human nature to both the woman and the man. Moral outrage mediated dehumanization when participants had low positive attitudes toward abortion in Study 1 and high positive attitudes in Study 2. Both studies showed a negative impact of the decision to have an abortion on the woman's perceived traditional professional competence. The results generally align with the findings from Italy and yield some practical implications on reducing abortion stigma. Future abortion stigma research should consider more gender-related factors. 相似文献

Consumers' increasing use of voice-activated artificial intelligence technologies is stimulating the development of a new line of research in the field of marketing aiming to analyse the branding implications in this innovative experiential context. The spread of so-called name-brand voice assistants (NBVAs) is creating interesting opportunities in terms of brand anthropomorphism. The brand anthropomorphisation strategies adopted by companies are poorly studied in the academic literature, and only one contribution has been made in the experiential field of NBVAs. Therefore, the objective of our work is to begin to fill this gap by investigating the pillars of brand anthropomorphisation strategies (i.e., activities and branding outcomes) in the specific NBVA context by adopting a managerial perspective. Therefore, we followed an exploratory qualitative approach based on in-depth personal interviews with practitioners engaged in these strategies in the automotive sector. The resulting cognitive map reveals the following three levels of strategic pillars: drivers (i.e., designing a human-like brand voice and human-like consumer-brand dialogue), intermediate outcomes (i.e., brand personality and the strength of consumer-brand relationships), and final outcomes (i.e., multidimensional brand loyalty). Our study enriches both the literature concerning brand anthropomorphisation strategies and the nascent stream on NBVAs and provides managerial guidelines in the new in-car NBVA context. 相似文献

The social and environmental impacts of the global fashion industry face increasing scrutiny. As such, consumers and brands look towards ‘sustainable fashion’ for low-impact alternatives. Simultaneously, visual social media platforms such as Instagram have become prevalent places for fashion advertising and discourse. To investigate this under-researched area, the current study utilises visual content and social network analysis to explore how sustainable fashion is presented on Instagram, specifically: (a) what visual characteristics are present within sustainable fashion content, and (b) in what broader contexts and communities is discussion of sustainable fashion taking place? Posts included under the hashtag #sustainablefashion (N = 650) were inspected for visual characteristics, including type of clothing, presence of person, post setting, presence of nature, and post format. Most posts were photographs located indoors with no person and no nature-based elements. The hashtags used alongside #sustainablefashion were analysed with Gephi software to establish a social network and community groups of related topics. Network analysis revealed four key community groups: online-promotional, artisan-traditional, eco-ethical, and Malay-online-selling. Secondhand fashion also appeared to be the most prominent sustainable fashion alternative on Instagram. This study is one of the first to investigate the characteristics of user-generated #sustainablefashion content on Instagram. Whilst social media is a burgeoning avenue for research, existing studies primarily investigate how these platforms can be harnessed for advertising, rather than what users themselves are already posting. Implications for brands who use this platform and opportunities for future research are discussed. 相似文献
