The Impact of Informational Intervention on HPV Vaccination Intention among Heterosexual Men.

Human papillomavirus (HPV) is one of the most common sexually transmitted infections (STIs). However, despite widespread under-vaccination amongst men and the importance of vaccinating both sexes to curb the spread of HPV, research has focused on promoting HPV vaccination predominantly amongst women. Therefore, the current study examines the effectiveness of different informational interventions in promoting vaccination intentions amongst heterosexual men. In a preregistered study of 583 unvaccinated adult men, we randomly assigned participants to one of four informational interventions aimed at promoting awareness of HPV risks and vaccine uptake: (1) risks to oneself (n = 145), (2) risks to their female partner (n = 144), (3) risks to oneself and their female partner (n = 153), and (4) general vaccine information (n = 153). Amongst participants reporting a sexual history (67%), intentions to get vaccinated significantly increased by 10.75 points on a 100-point scale (p < 0.01) after they received information about the risks of HPV for both themselves and their female partner, compared to receiving information about only their own HPV risk. These findings provide valuable guidance for public health officials and policymakers into the effectiveness of different messaging strategies in promoting HPV vaccination amongst adult male populations to increase vaccination rates.

Age-Related Differences in Moral Judgment: The Role of Probability Judgments.

Research suggests that moral evaluations change during adulthood. Older adults (75+) tend to judge accidentally harmful acts more severely than younger adults do, and this age-related difference is in part due to the greater negligence older adults attribute to the accidental harmdoers. Across two studies (N = 254), we find support for this claim and report the novel discovery that older adults' increased attribution of negligence, in turn, is associated with a higher perceived likelihood that the accident would occur. We propose that, because older adults perceive accidents as more likely than younger adults do, they condemn the agents and their actions more and even infer that the agents' omission to exercise due care is intentional. These findings refine our understanding of the cognitive processes underpinning moral judgment in older adulthood and highlight the role of subjective probability judgments in negligence attribution.

Language modality influences risk perception: Innovations read well but sound even better.

Psychological theories implicitly assume that the modality in which information is conveyed-spoken or written-leaves judgment and choice unaltered. Modality is rarely considered in textbooks on judgment and decision making, and the selection of modality in research is often based on convenience. We challenge this theoretical assumption. Three experiments (N = 984) show that the modality in which novel technologies are described systematically influences their perceived risk and benefit. Participants either read or heard advantages and disadvantages of novel technologies and then assessed their risk and benefit. In Study 1, spoken descriptions prompted more positive evaluations toward the technologies in terms of overall risks and benefits than written descriptions. Studies 2 and 3 replicated this modality effect and demonstrated that affect partially explains it, as spoken descriptions induced more positive feelings toward the new technologies than written descriptions. Study 3 (preregistered) showed that the influence of modality is unique to novel technologies and does not extend to familiar ones. These findings contribute theoretically to the understanding of the relationship between language and thought, and carry implications for survey research and the use of voice assistant technology.

Listening speaks to our intuition while reading promotes analytic thought.

It is widely assumed that thinking is independent of language modality because an argument is either logically valid or invalid regardless of whether we read or hear it. This is taken for granted in areas such as psychology, medicine, and the law. Contrary to this assumption, we demonstrate that thinking from spoken information leads to more intuitive performance compared with thinking from written information. Consequently, we propose that people think more intuitively in the spoken modality and more analytically in the written modality. This effect was robust in five experiments (N = 1,243), across a wide range of thinking tasks, from simple trivia questions to complex syllogisms, and it generalized across two different languages, English and Chinese. We show that this effect is consistent with neuroscientific findings and propose that modality dependence could result from how language modalities emerge in development and are used over time. This finding sheds new light on the way language influences thought and has important implications for research that relies on linguistic materials and for domains where thinking and reasoning are central such as law, medicine, and business.

The extreme illusion of understanding.

Though speakers and listeners monitor communication success, they systematically overestimate it. We report an extreme illusion of understanding that exists even without shared language. Native Mandarin Chinese speakers overestimated how well native English-speaking Americans understood what they said in Chinese, even when they were informed that the listeners knew no Chinese. These listeners also believed they understood the intentions of the Chinese speakers much more than they actually did. This extreme illusion impacts theories of speech monitoring and may be consequential in real-life, where miscommunication is costly. (PsycInfo Database Record (c) 2022 APA, all rights reserved).

Use of a language intervention to reduce vaccine hesitancy.

Vaccine hesitancy is a major global challenge facing COVID-19 immunization programs. Its main source is low public trust in the safety and effectiveness of the vaccine. In a preregistered experimental study, we investigated how using a foreign language when communicating COVID-19 vaccine information influences vaccine acceptance. Hong Kong Chinese residents (N = 611) received COVID-19 vaccine information either in their native Chinese or in English. English increased trust in the safety and effectiveness of the vaccine and, as a result, reduced vaccine hesitancy. This indicates that language can impact vaccine attitudes and demonstrate the potential of language interventions for a low cost, actionable strategy to curtail vaccine hesitancy amongst bilingual populations. Language interventions could contribute towards achieving the United Nations Sustainable Development Goal of health and well-being.

The influence of native language in shaping judgment and choice.

As a result of globalization, millions of people operate in a language that they comprehend well but is not their native tongue. This paper focuses on how the nativeness of the language of a communication influences judgments and decisions. We review studies that compare decision making while people use a native language to when they use a nonnative language they understand well. The evidence shows that a nonnative language decreases the impact that emotions and socio-moral norms have on users, thereby reducing well-known judgmental biases and norm-related behavior. This effect of nonnative or foreign language brings to light the important role that the native language plays routinely in judgment and decision making. It suggests that the native language is not a simple carrier of meaning. Instead, it reveals that our native language serves as a carrier of emotions and socio-moral norms which in turn govern judgments and choices.

Breaking magic: Foreign language suppresses superstition.

In three studies, we found that reading information in a foreign language can suppress common superstitious beliefs. Participants read scenarios in either their native or a foreign language. In each scenario, participants were asked to imagine performing an action (e.g., submitting a job application) under a superstitious circumstance (e.g., broken mirror, four-leaf clover) and to rate how they would feel. Overall, foreign language prompted less negative feelings towards bad-luck scenarios and less positive feelings towards good-luck scenarios, while it exerted no influence on non-superstitious, control scenarios. We attribute these findings to language-dependent memory. Superstitious beliefs are typically acquired and used in contexts involving the native language. As a result, the native language evokes them more forcefully than a foreign language.

Many moral buttons or just one? Evidence from emotional facial expressions.

We investigated whether moral violations involving harm selectively elicit anger, whereas purity violations selectively elicit disgust, as predicted by the Moral Foundations Theory (MFT). We analysed participants' spontaneous facial expressions as they listened to scenarios depicting moral violations of harm and purity. As predicted by MFT, anger reactions were elicited more frequently by harmful than by impure actions. However, violations of purity elicited more smiling reactions and expressions of anger than of disgust. This effect was found both in a classic set of scenarios and in a new set in which the different kinds of violations were matched on weirdness. Overall, these findings are at odds with predictions derived from MFT and provide support for "monist" accounts that posit harm at the basis of all moral violations. However, we found that smiles were differentially linked to purity violations, which leaves open the possibility of distinct moral modules.

Moral Judgment in Old Age.

Younger (21-39 years) and older (63-90 years) adults were presented with scenarios illustrating either harmful or helpful actions. Each scenario provided information about the agent's intention, either neutral or valenced (harmful/helpful), and the outcome of his or her action, either neutral or valenced. Participants were asked to rate how morally good or bad the agent's action was. In judging harmful actions, older participants relied less on intentions and more on outcomes compared to younger participants. This age-related difference was associated with a decline in older adults' theory of mind abilities. However, we did not find evidence of any significant age-related difference in the evaluations of helpful actions. We argue that the selective association of aging with changes in the evaluation of harmful but not helpful actions may be due also to motivational factors and highlight some implications of the present findings for judicial systems.

Foreign language affects the contribution of intentions and outcomes to moral judgment.

We examine whether the use of a foreign language, as opposed to the native language, influences the relative weight intentions versus outcomes carry in moral evaluations. In Study 1, participants were presented with actions that had positive outcomes but were motivated by dubious intentions, while in Study 2 with actions that had negative outcomes but were motivated by positive intentions. Participants received the materials either in their native or a foreign language. Foreign language prompted more positive moral evaluations in Study 1 and less positive evaluations in Study 2. These results show that foreign language reduces the relative weight placed on intentions versus outcomes. We discuss several theoretical accounts that are consistent with the results such as that foreign language attenuates emotions (triggered by intentions) or it depletes cognitive resources.

The Foreign Language Effect on Moral Judgment: The Role of Emotions and Norms.

We investigated whether and why the use of a foreign language influences moral judgment. We studied the trolley and footbridge dilemmas, which propose an action that involves killing one individual to save five. In line with prior work, the use of a foreign language increased the endorsement of such consequentialist actions for the footbridge dilemma, but not for the trolley dilemma. But contrary to recent theorizing, this effect was not driven by an attenuation of emotions. An attenuation of emotions was found in both dilemmas, and it did not mediate the foreign language effect on moral judgment. An examination of additional scenarios revealed that foreign language influenced moral judgment when the proposed action involved a social or moral norm violation. We propose that foreign language influences moral judgment by reducing access to normative knowledge.

The effect of foreign language in judgments of risk and benefit: The role of affect.

As a result of globalization, policymakers and citizens are increasingly communicating in foreign languages. This article investigates whether communicating in a foreign language influences lay judgments of risk and benefit regarding specific hazards such as "traveling by airplane," "climate change," and "biotechnology." Merging findings from bilingual and risk perception research, we hypothesized that stimuli described in a foreign language, as opposed to the native tongue, would prompt more positive overall affect and through that induce lower judgments of risk and higher judgments of benefit. Two studies support this foreign language hypothesis. Contrary to recent proposals that foreign language influences judgment by promoting deliberate processing, we show that it can also influence judgment through emotional processing. The present findings carry implications for international policy, such as United Nations decisions on environmental issues.
