In three preregistered studies, we investigated whether implicit treatment expectations, using a relational implicit measure (the MT-PEP), vary between participants provided opposing information about novel medical treatments (Studies 1 and 2) or who responded based on normative beliefs toward common over-the-counter drugs (Study 3). The studies revealed large Cohen's d effect sizes of both novel and well-known treatment information within the implicit measure. The studies also provide evidence of convergent validity, with MT-PEP scores associated with explicit beliefs about medicine and over-the-counter drug familiarity. Implicit treatment expectations can be assessed and offer a novel tool for the intersection of social psychology and medicine.

A stereotype is a generalization about a class of people which is often used to make probabilistic predictions about individuals within that class. Can stereotypes can be understood as conditional probabilities that distinguish among groups in ways that follow Bayesian posterior prediction? For instance, the stereotype of Germans as industrious can be understood as the conditional probability of someone being industrious given that they are German. Whether such representations follow Bayes' rule was tested in a replication and extension of past work. Across three studies (N = 2,652), we found that people's judgments of different social categories were appropriately Bayesian, in that their direct posterior predictions were aligned with what Bayes' rule suggests they should be. Moreover, across social categories, traits with a high calculated diagnostic ratio generally distinguished stereotypic from non-stereotypic traits. The effects of cognitive ability, political orientation, and motivated stereotyping were also explored.

Conspiracy theories often feature moral concerns and thrive when societal institutions are perceived as untrustworthy. However, limited research exists exploring whether moral concerns are associated with conspiracy thinking and if this link is strengthened when institutional trust is low. Two studies employing correlational (N = 423) and experimental (N = 381) designs found that liberty moral concerns, and to a lesser extent binding concerns, are associated with increased conspiratorial thinking, particularly when institutional trust is low. Moral concerns about liberty may contribute to increased conspiratorial thinking and low institutional trust may play a key role in exacerbating this link.

Although there have been studies in the past that have highlighted the important role of leader traits in motivating employee innovation behavior, leader perfectionism has been scarcely investigated in this context. This study attempts to explore whether leader perfectionism directed toward employees can facilitate or hinder employee innovation behavior. Based on the transactional model of stress, we propose and test a moderated mediation model using data from a multi-wave, multi-source survey of 334 leader-employee questionnaires. The results show that, for employees with high self-efficacy, leader perfectionism has a positive effect on their challenge stress, which in turn promotes employee innovation behavior; Meanwhile, for employees with low self-efficacy, leader perfectionism has a positive effect on their hindrance stress, thereby discouraging employee innovation behavior. This study has significant theoretical and practical implications as it highlights the underlying relationship between leader perfectionism and employee innovation behavior.

This study explored the impact of customer mistreatment on counterproductive work behavior (CWB) and the moderating role of supervisor responses (self-sacrificial and self-serving leadership) to clarify why customer-directed CWB occurs and how it can be reduced. A sample of 392 customer-facing employees in the USA completed measures assessing the meaningfulness of work and self-sacrificial and self-serving leadership experiences. The meaningfulness of work moderated the relationship between customer mistreatment and employee anger, and a three-way interaction was found between employee anger and self-sacrificial and self-serving leadership on customer-directed CWB. Implications for managing customer mistreatment and fostering meaningful work to promote employee well-being are discussed.

Risk communication involves conveying potential risks to the audience. It's crucial for shaping behavior and influencing individual well-being. Previous research predominantly focused on verbal and written aspects of risk communication, with less emphasis on nonverbal cues like vocal tone. Addressing this gap, our study explores the impact of competent and warm vocal tones on risk communication across two risky decision-making paradigms, the Balloon Analogue Risk Task (BART) in Study 1 and the Gambling Task in Study 2. Results show that competent and warm vocal tones are more persuasive than neutral tones, and their effectiveness varies in different decision-making scenarios. Additionally, participants' perceived competence and warmth of vocal tones mediate this persuasiveness. This study enhances our theoretical understanding of risk communication by incorporating the impact of vocal tones. Also, it carries practical implications for marketers and practitioners, demonstrating the importance of using voice as a medium to persuade in real-world scenarios.

Familiar information is more likely to be accepted as true. This illusory truth effect has a tremendous negative impact on misinformation intervention. Previous studies focused on the familiarity from repeated exposure in the laboratory, ignoring preexisting familiarity with real-world misinformation. Over three studies (total N = 337), we investigated the cognitive mechanisms behind the truth biases from these two familiarity sources, and whether fact-checking can curb such biased truth perceptions. Studies 1 and 2 found robust truth effects induced by two sources of familiarity but with different cognitive processes. According to the cognitive process model, repetition-induced familiarity reduced decision prudence. Preexisting familiarity instead enhanced truth-congruent evidence accumulation. Study 3 showed that pre-exposing statements with warning flags eliminated the bias to truth induced by repetition but not that from preexisting familiarity. These repeated statements with warning labels also reduced decision caution. These findings furthered the understanding of how different sources of familiarity affect truth perceptions and undermine the intervention through different cognitive processes.

The present study examined the thematic composition and temporal evolution of social psychology through a co-citation network analysis of 80,350 articles published from 1970 through 2022. Six primary thematic clusters were identified: a broad "Classic Social Psychology" cluster most prominent in the 1970s and 1980s; "Traits & Affect" and "Social Cognition" clusters most influential in the 1990s; and "The Self," "Intergroup Relations," and "Big Five" clusters emerging after 2000. A small seventh cluster dedicated to COVID-19 and conspiracy theories emerged around 2021. These trends fit a narrative of generational shifts within distinct social and personality psychology traditions.

A pro-environmental behavior (PEB) intervention may increase the adoption of other PEBs that were not targeted by the intervention, leading to a positive spillover effect. Communication that both support autonomy, as defined by self-determination theory, and compliance with descriptive norms may promote the targeted PEBs and positive spillover effect. Such communication may enhance autonomous motivation to adopt PEBs. A pilot study (N = 350) about waste management in a university campus found that autonomous communication supplemented by normative information influenced both targeted and non-targeted behavioral intentions, compared to autonomous-only and controlling communication. Findings were replicated in a main study (N = 629). An intervention combining autonomy support and descriptive norms increased the likelihood of a positive spillover effect in contrast to an intervention combining controlling communication and descriptive norms. In both studies, autonomous motivation mediated the positive spillover effect. Results suggest that communication that promotes autonomous motivation by fulfilling basic self-determination needs may have a broader effect on a wider range of PEBs.

Empathy, whether state or trait, is an individual's ability to adopt another's perspective, feel another's feelings, or identify with another's situation (Campbell & Babrow, 2004; Davis, 1983; Nezlek etal., 2007). Research reliably shows relationships between empathy and parasocial interactions (e.g. psychological engagements with fictional characters; Giles, 2002; Tsao, 1996; Zillmann, 1994). The current study sought to identify the relationship between the type of parasocial interactions and subsequent changes in state-level empathy via an experimental design. Results indicate state-level empathy changes are contingent upon valence (i.e. Favorite vs. Least Favorite) and status (i.e. Real vs. Parasocial) of the imagined interaction.
