Inverse statistics and misperception of exponential growth

Exponential growth presented by numerical series or graphs is grossly underestimated by human subjects. This misperception was considerably lessened by presenting decreasing functions; this conclusion holds for both numeric and graphic stimuli. In the numerical conditions, about 25% of the subjects performed according to the statistical norm. In contrast with previous results, considerable individual differences with respect to sensitivity for rate of growth were observed. This finding was interpreted in terms of task difficulty: Extrapolation of ascending series is too difficult a task to be discriminative. Extrapolation of descending series is much easier, and may therefore better discriminate among subjects.     

儿童自我意识发展机制初探

本文在对以往有关研究分析的基础上指出,自尊需要早在自我意识成熟之前就已存在,并且是儿童自我意识发展的内在动力,当儿童逐渐在多方面认识事件的自我意义,从而更为主动、合理地满足自尊需要时,自我意识便得以发展.儿童的自尊需要和自我认识水平相互作用,不仅形成了自我意识的纵向发展差异,而且形成了横向个体差异。

Intergenerational relationships and marriage in China: Within-family longitudinal associations and between-family differences

Marriage is embedded in the web of spouses' broader social ties, and relationship quality with parents and parents-in-law is associated with marital quality. Guided by Family Systems theory and using three waves of dyadic data from 268 Chinese different-sex couples across the first several years of marriage, we first conducted a Random-Intercept Actor-Partner Interdependence Cross-lagged Panel Model (RI-APIM-CLPM) to examine the within-family longitudinal associations among husbands' and wives' relationship quality with parents, parents-in-law, and spouse. Then, husbands' and wives' filial obligations were added as predictors of between-family differences in their own and their partner's relationship quality in the three social ties. Among husbands, increased relationship quality in one social tie (e.g., with parents) predicted reductions in relationship quality in the other social ties (e.g., relationships with parents-in-law and marital quality). Our examination of between-family differences demonstrated that high levels of filial obligations predicted higher intergenerational relationship quality and marital quality. By simultaneously considering the within-family associations of multiple social ties and how filial obligations account for between-family differences in relationship quality, we contribute to a nuanced understanding of how Chinese couples' romantic partnerships are embedded in their broader family system.     

Bi-directional relations between behavioral problems and executive function: Assessing the longitudinal development of self-regulation

During childhood, the ability to limit problem behaviors (i.e., externalizing) and the capacity for cognitive regulation (i.e., executive function) are often understood to develop in tandem, and together constitute two major components of self-regulation research. The current study examines bi-directional relations between behavioral problems and executive function over the course of childhood and adolescence. Relying on a diverse sample of children growing up in low-income neighborhoods, we applied a random intercept cross-lagged panel model to longitudinally test associations between behavioral problems and executive function from age 4 through age 16. With this approach, which disaggregated between- and within-child variation, we did not observe significant cross-lagged paths, suggesting that within-child development in one domain did not strongly relate to development in the other. We also observed a moderate correlation between the stable between-child components of behavioral problems and executive function over time in our preferred model, suggesting that these two domains may be relatively distinct when modeled from early childhood through adolescence.     

Using humor to increase COVID-19 vaccination intention for the unvaccinated: The moderating role of trust in government

Since COVID-19 was declared a global pandemic, scholars and practitioners have put much effort into testing effective advertising strategies for COVID-19 vaccinations. Guided by humor theories, this study aimed to examine (1) the effect of humor on persuading COVID-19 vaccination and (2) the moderating role of trust in government for the unvaccinated population. Across two studies (college students and general adult populations), for lower trust in government individuals, through greater public service advertisement (PSA) processing depth and believability, there was a higher vaccination intention after the humor (non-humor) advertisement. For higher trust in government individuals, there was evidence that the vaccination intention was lowered after the humor (vs. non-humor) message through lowered PSA processing depth and believability. This study expands humor theory into testing COVID-19 vaccination messages while considering an individual psychological factor, trust in the government, that has emerged as an essential determinant to COVID-19 messaging. The contributions to COVID-19 vaccination advertising strategy and advertising to the unvaccinated population, in general, are discussed.     

How do friendship artificial intelligence chatbots (FAIC) benefit the continuance using intention and customer engagement?

Although there have been many AI chatbots in industry service, social media, and e-commerce platforms, research on AI chatbots such as Replika, neglected the effects of human-like traits on users' continuance using intention. This article aims to explore the main effects of human-like traits (perceived warmth vs. perceived competence) of friendship AI chatbots (FAIC) on continuance using intention and customer engagement, and the moderating effects of the need to belong and information sensitivity. Three studies are conducted to collect data (N_total = 1420). Our findings of Study 1 demonstrate that perceived warmth and perceived competence can increase the continuance using intention to FAIC and customer engagement, and perceived usefulness plays a mediating role in our conceptual model. Additionally, consumers' need to belong (high vs. low) (Study 2) and information sensitivity (high vs. low) (Study 3) related to chat contents moderate the main effects significantly. This article contributes to the literature on the relationship between FAIC and consumers by presenting the influence of perceived warmth and perceived competence and establishing the underlying process. Analogously, the findings can be beneficial for marketers and firms in designing and developing the coding program of FAIC to promote consumers' continuance using intention and customer engagement.     

An exploratory study of consumer switching behavior in platform businesses: A mixed methods approach

This study investigates consumer switching behavior factors in platform businesses. This study reports a two-phase study of switching behavior. The first phase, Latent Dirichlet Allocation topic analysis, was conducted by collecting reviews and comments to find out consumers' potential switching behavior factors. The second phase was the interview with the consumer who did the switching behavior as to why they made the switching behavior. Besides, among the potential switching behavior factors, actual switching behavior factors were compared. It links quantitative and qualitative phases in exploratory sequential mixed methods design. The switching behavior factors were identified by applying the push-pull-mooring framework. The result of the study on music platforms' push effects is price perception, pull effects are promotion and algorithm recommendation, and mooring effects are payment convenience, switching cost, and reward. In Over-the-top (OTT), platforms' push effect is a lack of content, pull effects are promotion, WOM, and diversity of content, and mooring effects are content expectations, social networks, payment convenience, and convenience of watching. In e-commerce platforms' push effects are technical issues, delivery cost, and lack of trust, pull effects are service line extension, and convenience of use, mooring effects are reward, payment convenience, and convenience of access to my data. This work contributes to the growing body of studies investigating the switching behavior factor in each platform business. Also, the study makes recommendations to aid platform marketing managers in understanding the impact of push-pull-mooring variables.
