Ubiquitous Internet access has provided easy access to information and has influenced users' attention and knowledge management. In an online information service context, this research examines how the perception of easy access to information affects strategies to learn two types of information: "what it is" and "how to access it." This study also examines how the learning process is moderated by individual differences in working memory capacity, which can determine efficient management of attentional resources. The results show that individuals, especially those who rank high in working memory capacity, are less likely to remember the details but are more likely to remember how to access the information (e.g., a keyword for a search engine query). Those with higher working memory capacity are also more likely to ensure easy access to information by subscribing to information sources. The findings suggest that cognitive miserliness is not due to users' lack of cognitive capacity but to the accessibility of online information and efficient execution of attentional resources.

Beliefs have long been theorized to predict behaviors and thus have been the target of many interventions aimed at changing false beliefs in the population. But does changing beliefs translate into predictable changes in behaviors? Here, we investigated the impact of belief change on behavioral change across two experiments (N = 576). Participants rated the accuracy of a set of health-related statements and chose corresponding campaigns to which they could donate funds in an incentivized-choice task. They were then provided with relevant evidence in favor of the correct statements and against the incorrect statements. Finally, they rated the accuracy of the initial set of statements again and were given a chance to change their donation choices. We found that evidence changed beliefs and this, in turn, led to behavioral change. In a preregistered follow-up experiment, we replicated these findings with politically charged topics and found a partisan asymmetry in the effect, such that belief change triggered behavioral change only for Democrats on Democratic topics, but not for Democrats on Republican topics or for Republicans on either topic. We discuss the implications of this work in the context of interventions aimed at stimulating climate action or preventative health behaviors.

To further understand how to combat COVID-19 vaccination hesitancy, we examined the effects of pro-vaccine expert consensus messaging on lay attitudes about vaccine safety and intention to get a COVID-19 vaccine. We surveyed 729 unvaccinated individuals from four countries in the early stages of the pandemic and 472 unvaccinated individuals from two countries after 2 years of the pandemic. We found belief of vaccine safety strongly correlated with intention to vaccinate in the first sample and less strongly in the second. We also found that consensus messaging improved attitudes toward vaccination even for participants who did not believe the vaccine is safe nor intended to get it. The persuasiveness of expert consensus was unaffected by exposing participants' lack of knowledge about vaccines. We conclude that highlighting expert consensus may be a way to increase support toward COVID-19 vaccination in those hesitant or skeptical.

Visual displays, such as icon arrays and risk ladders, are often used to communicate numerical health information. Number lines improve reasoning with rational numbers but are seldom used in health contexts. College students solved ratio problems related to COVID-19 (e.g., number of deaths and number of cases) in one of four randomly assigned conditions: icon arrays, risk ladders, number lines, or no accompanying visual display. As predicted, number lines facilitated performance on these problems-the number line condition outperformed the other visual display conditions, which did not perform any better than the no visual display condition. In addition, higher performance on the health-related ratio problems was associated with higher COVID-19 worry for oneself and others, higher perceptions of COVID-19 severity, and higher endorsement of intentions to engage in preventive health behaviors, even when controlling for baseline math skills. These findings have important implications for effectively presenting health statistics. (PsycInfo Database Record (c) 2023 APA, all rights reserved).

The public tends to exaggerate the dangers of nuclear energy, mistakenly associating it with various environmental problems such as ozone depletion and the production of CO₂. First, we investigate the acquisition of misconceptions about nuclear energy. In Experiments 1 (N = 198, United Kingdom) and 2 (N = 204, France), participants were more likely to develop new negative misconceptions about nuclear energy, compared to renewables or even some fossil fuels. Participants were also more likely to attribute the emission of hazardous substances produced by renewables to nuclear energy than to the energy sources actually emitting it. This suggests that specific misconceptions about nuclear energy are likely the by-products of negative perceptions of nuclear energy. Second, we ask whether correcting specific misconceptions leads to less negative attitudes about nuclear energy. In Experiments 3 (N = 296, United Kingdom.) and 4 (N = 305, France), participants were exposed to pronuclear energy arguments, one of which informed them of its low CO₂ emissions. This argument led to a decrease in the perception that nuclear energy contributes to climate change. Thus, even if specific misconceptions about nuclear energy derive from overall negative perceptions, addressing these misconceptions can still help align public opinion with expert opinion.

Concepts are grounded in mental simulation of sensory information, but the exact role it plays in everyday cognition is unknown. Here, we investigate its role in an important conceptual domain relevant for everyday behavior-food. We conducted two preregistered studies to test whether multimodal mental simulation is linked to attractiveness of food concepts. In Study 1, using the Lancaster Sensorimotor norms for a variety of concepts, we found unhealthy food concepts are more strongly associated with gustation, olfaction, and interoception than healthy food concepts. Importantly, these associations mediated the relationship between food healthiness and food attractiveness. In Study 2, we collected new sensory ratings with food words only and found unhealthy food concepts were more strongly associated with all perceptual modalities than healthy food concepts. Again, these associations mediated the relationship between healthiness and attractiveness. The mediating role of sensory associations to food attractiveness was also affected by context. Specifically, when participants thought about food in an eating context cued by verbal instruction, mediation by perceptual strength was weaker. Overall, we find multimodal sensory experience underlies people's belief that unhealthy food is more attractive than healthy food. This suggests mental simulation has an important role in goal-directed behavior. (PsycInfo Database Record (c) 2023 APA, all rights reserved).

Interruptions are an inevitable, and often negative, part of everyday life that increase both errors and the time needed to complete even menial tasks. However, existing research suggests that being given time to prepare for a pending interruption-a lag time-can mitigate some of the interruption costs. To understand better why interruption lags are effective, we present a series of three experiments in which we develop and test a novel sequential decision-making paradigm, the mazing race. We find that interruption lags were only beneficial when participants had a clear strategy for how to complete the task, allowing them to avoid specific errors. In the final experiment, we attempted to use what we learned about the kinds of errors introduced by interruptions to develop a feedback-based intervention, aimed at dealing with situations in which interruption lags are not possible. We found that feedback was, only in certain situations, an effective replacement for an interruption lag. Overall, however, because the usefulness of interruption lags depend on the specific strategy a participant adopts, developing generic interventions to replace interruption lags is likely to be difficult.
