Confronting the Bullies, Comforting the Victim, or Reporting to University Staff? Prosocial Intentions Towards Social Exclusion in University Students

AbstractSocial exclusion as a form of in-person relational bullying in higher education (HE) leads to loneliness in students and puts their mental well-being at risk. Utilising and extending the theory of planned behaviour (TPB), we investigated prosocial intentions towards bullying in HE students. We included empathic concern and anticipated regret to potentially explain differences in three behavioural intentions towards bullying: comforting the victim, confronting the bullies, and reporting the bullying to the university. The sample comprised 419 participants in an online sample from the UK (MAge = 22.76 years, SDAge = 4.02 years; 47.0% male, 50.6% female, 2.4% other) who filled in a digital questionnaire consisting of a short vignette describing an in-person situation of relational bullying. Applying structural equation modelling, we examined the three prosocial behavioural intentions towards bullying as outcome variables in two models while controlling for age, gender, and socially desirable responding. Traditional TPB predictors were positively associated with confronting the bullies. Empathic concern and anticipated regret were positively associated with comforting the victim. These results demonstrate how cognitive and emotional predictors uniquely contribute to prosocial intentions towards bullying among students. We discuss practical implications for the design of anti-bullying strategies in HE.

Day-to-day associations of intersectional minority stressors with sleep health in sexual and gender minority people of color.

To determine the day-to-day associations between minority stressors (i.e., anticipated and experienced discrimination) and sleep health outcomes (i.e., total sleep time (TST), sleep disturbances, and sleep-related impairment) among sexual and gender minority (SGM) people of color. An online sample of SGM people of color living in the United States participated in a 30-day daily diary study. Daily anticipated and experienced discrimination as well as subjective sleep outcomes were assessed via electronic diaries using validated measures. Wrist-worn actigraphy was used to objectively assess TST. Multilevel linear models (MLMs) were used to estimate the independent associations of daily intersectional minority stressors with subsequent sleep outcomes, adjusted for demographic factors and lifetime discrimination. The sample included 43 SGM people of color with a mean age of 27.0 years (± 7.7) of which 84% were Latinx, 47% were multiracial, and 37% were bisexual. Results of MLMs indicated that greater report of daily experienced discrimination was positively associated with same-night sleep disturbances, B (SE) = 0.45 (0.10), p < .001. Daily anticipated discrimination was positively associated with sleep-related impairment on the following day, B (SE) = 0.77 (0.17), p < .001. However, daily anticipated and experienced discrimination were not associated with same-night TST. Findings highlight the importance of considering the differential effects of daily intersectional minority stressors on the sleep health of SGM people of color. Further research is needed to identify factors driving the link between daily minority stressors and sleep outcomes to inform sleep health interventions tailored to this population.

Vicarious racism, ethnic/racial identity, and sleep among Asian Americans.

Vicarious racism-witnessing or hearing about other individuals of one's ethnic/racial group being the target of racism-has been salient among Asian Americans during the coronavirus disease (COVID-19) pandemic. There is emerging evidence that such experiences adversely impact several health-related outcomes, including sleep. The present study examines associations between vicarious racism and subjective sleep duration and quality, and the potential moderating role of ethnic/racial identity (ERI). Multivariable regression models assessed the association between vicarious racism, private regard, and centrality on self-reported sleep disturbance and duration. The sample consisted of an online sample of 600 Asian American adults (Mage = 38.55, SDage = 17.11; 65.17% female; 60% ≥ Bachelor's degree) recruited from May to June 2020. Vicarious racism was associated with compromised sleep quality and duration, including after adjustment for sociodemographic variables that have been linked to sleep. Private regard toward one's own ethnic/racial group and centrality of ethnicity/race to self-identity buffered the association between vicarious racism and sleep quality and duration. Adverse effects of high vicarious racism on sleep quality and duration were lessened among respondents reporting high levels of ERI private regard and centrality. Findings from this study extend research on racism and sleep by examining vicarious racism, an understudied facet of racism, and by focusing specifically on Asian Americans and in the context of the COVID-19 pandemic. Future research and practice should consider expanding research on discrimination to include a broader range of unjust experiences. Vicarious racism contributes to health hazards experienced by Asian Americans during the COVID-19 pandemic. (PsycInfo Database Record (c) 2024 APA, all rights reserved).

All the Working World’s A Stage: Narcissism, Work Values, and Vocational Preferences

Prior research has established that individuals high in narcissism may favor certain professions over others, but the reasons for this remain speculative. The present study employs the Narcissistic Admiration and Rivalry Concept model to differentiate between two motivational drivers of narcissism – admiration (desire for praise) and rivalry (desire to denigrate others) – and explores their influence on vocational preferences in an online sample of 386 full-time U.S. employees. Further, we examine the role of work values (achievement, comfort, status, altruism, safety, autonomy) as mediators in these preferences. By understanding how narcissism’s two dimensions shape interest in various vocations, we expand upon previous research on subclinical personality and career preferences, offering organizations a way to proactively identify workers with potentially derailing personality characteristics. Finding that work values mediate the relationship between narcissism and vocational interests suggests the importance of investigating this mediating mechanism with other bright and dark traits.

Children’s evaluations of culturally diverse lunchbox foods

Previous research indicates that children make ingroup–outgroup judgments based on notions of food conventionality and that ethnic minority children have been teased or bullied for bringing non-conventional foods to school. This series of three studies experimentally investigated U.S. school-age children’s evaluations of culturally diverse lunchbox foods. Study 1 examined an online sample of children aged 5 to 12 years and their evaluations of foods from four cultures (mainstream American, Chinese, Indian, and Mexican) on the taste, smell, and messiness of the food, the appropriateness of bringing the food to school, and whether “cool kids” eat the food. Compared with the mainstream American lunchbox, children rated the Chinese, Indian, and Mexican lunchboxes as less tasty, more messy, and less likely that cool kids would bring those foods to school. In Studies 2 and 3, we examined children’s behavioral choices in a hypothetical cafeteria. In both studies, we found that the match between children’s own lunch preferences and what was displayed in the mainstream American lunchbox was the only predictor of children’s choice to sit at the table with the American lunchbox. Individual variables (e.g., child age, food pickiness) and contextual variables (e.g., neighborhood diversity) did not predict children’s table choices. This research highlights children’s understanding of familiarity and conventionality of foods and the social consequences of their behavioral choices.

Impact of Additional Duties on the Livestock Extension Services in Punjab: A Veterinary Field Staff Perspective

This study investigates the impact of additional duties of veterinary field staff on the delivery of livestock extension services. The current study was conducted in Punjab province. Administratively, this province consists of nine divisions. All veterinary officers (VOs) and veterinary assistants (VAs) of Punjab were considered as the population of the study. A complete list of veterinary field staff was collected from the Punjab Livestock and Dairy Development Department office. The sample size was calculated with the help of the online sample size calculator www.surveysystem.com with a 5% confidence interval and 95% confidence level. The sample size was drawn through a proportionate simple random sampling technique from two population subgroups, i.e., VOs and VAs. The study results revealed that 85.1% of respondents said they disliked performing the additional duties. About 93% of the respondents reported that the livestock department should have considered their will before assigning additional duties. Additional duties negatively affect the working efficiency of the field staff, as reported by 87.8% of VOs and 93.5% of VAs. Most respondents (58.8%) reported that they have to suspend their routine departmental services upon additional duties. It means, the assignment of additional duties seriously affects the departmental routine extension services. It is suggested that Livestock and Dairy Development, Punjab, should employ exceptional field staff for such additional duties to reduce the extra and irrelevant work burden on veterinary field staff.

Perceived reputation moderates the link between honor concerns and depressive symptoms

ABSTRACT Prior research has shown that U.S. cultures of honor have higher rates of depression and suicide. While links between honor endorsement and suicide have been established in the literature, a direct test of the primary mechanism underlying this association (reputation damage leading to depression) has not yet been tested. The current study sought to address whether shifts in perceived reputation might be associated with higher levels of depression for honor endorsing individuals. An online sample of 305 participants were tracked across two time points, assessing perceived individual reputation and perceived family reputation, as well as depressive symptoms. Analyses revealed that higher levels of honor concern at Time 1 were linked with higher levels of depressive symptoms at Time 2, but only for those with low perceived reputation – these relationships held while controlling for the stability in reputation and depression across time points, as well as controlling for participants’ gender. Findings provide the first empirical evidence that reputation damage may contribute to detriments in mental health in honor endorsers.

The Relationship Between Psychological Empowerment and Clinical Decision-Making Among Staff Nurses in Governmental Hospital in Al-Baha, Saudi Arabia.

Background The Saudi Arabian government has published its 2030 vision for improving health care to meet worldwide standards for the nursing profession. To fulfill this vision, building large-scale healthcare facilities is necessary. Among the most common occupations, nursing is vital to health care systems. Although working in health care institutions is challenging, demanding, and comprehensive, they are created to save lives and enhance patient satisfaction. Therefore, health care organizations must seek to develop psychologically empowered and decision-making nurses who can help meet clients' demands and enhance patient care, safety, quality, and outcomes. This study aims to determine the association between psychological empowerment (PE) and clinical decision-making (CDM) among staff nurses. Methods This study employed a quantitative cross-sectional correlation design. Three Saudi Ministry of Health-affiliated hospitals in the Al-Baha region were included. The sample size was calculated using the Raosoft online sample size calculator, with a total of 318 participants. The study sample included nurses working in inpatient, outpatient, and critical care departments. Convenience sampling techniques with inclusion and exclusion criteria were employed. An online survey with three sections was used for data collection: sociodemographic characteristics, the psychological empowerment instrument, and the nursing decision-making instrument. Data collection began at the beginning of February 2023 and was completed by the beginning of April 2023. Results The participants were 318 nurses working in critical areas, inpatient, and outpatient departments at three governmental hospitals in the Al-Baha region. Overall, 285 participants (89.6%) had a high level of PE, and the majority, 263 participants (82.7%), exhibited flexible-oriented decision-making. Approximately three-quarters of the sample, 281 participants (88.4%), were female, and more than half of the staff nurses, 187 participants (58.8%), were married. The majority of participants, 250 (78.6%), had a bachelor's degree. Regarding professional experience, most staff nurses, 134 participants (42.1%), had between one and five years of experience, and the majority worked in inpatient units, 160 participants (50.3%), while 104 (32.7%) worked in critical care. Conclusion The current study found a significant association between nurses' PE and CDM. Nurses with the highest PE were the most flexible in their CDM. Moreover, the findings of this study offer some points that nurse managers and leaders can use to generate empowerment and make their staff better decision-makers. One recommendation is to develop training and coaching programs to enhance PE among staff nurses, thereby raising their work meaningfulness, which would reflect in better CDM. Additionally, this study recommends that future research be conducted to examine how PE affects CDM.

The Impact of Relational Depth on Subjective Well-being in Close Relationships in the Community

Relational depth (RD)—moments of profound connection and engagement between two people—is a humanistic–existential construct, showing preliminary association with psychological growth in psychotherapy. This research investigates the impact of RD, alongside relationship satisfaction and emotional intimacy, on subjective well-being in close relationships in the community. Psychometric properties of latent variables were assessed in a stratified online sample of 497 participants in the United Kingdom (47.1% male, 52.1% female, 1% other; mean age 45.7 [ SD = 15.9]; 86.5% white, 7.8% Asian, 3.2% Black, 1.4% mixed and 1% other), followed by lagged regressions, and moderation analyses to assess the role of RD on Personal Well-being Score (PWS). Data were collected at two further time points at 3-month intervals on a stratified subset of participants ( n = 297 and n = 267). RD emerged as a significant predictor of subjective well-being in close relationships in the community and was moderated by emotional intimacy and relationship satisfaction. This study provides the first robust evidence of the relevance and impact of the humanistic–existential construct of RD on well-being beyond a psychotherapy context. This points to the value of practices that can facilitate RD experiences in the community.

A Perspective of Q-value Estimation on Offline-to-Online Reinforcement Learning

Offline-to-online Reinforcement Learning (O2O RL) aims to improve the performance of offline pretrained policy using only a few online samples. Built on offline RL algorithms, most O2O methods focus on the balance between RL objective and pessimism, or the utilization of offline and online samples. In this paper, from a novel perspective, we systematically study the challenges that remain in O2O RL and identify that the reason behind the slow improvement of the performance and the instability of online finetuning lies in the inaccurate Q-value estimation inherited from offline pretraining. Specifically, we demonstrate that the estimation bias and the inaccurate rank of Q-value cause a misleading signal for the policy update, making the standard offline RL algorithms, such as CQL and TD3-BC, ineffective in the online finetuning. Based on this observation, we address the problem of Q-value estimation by two techniques: (1) perturbed value update and (2) increased frequency of Q-value updates. The first technique smooths out biased Q-value estimation with sharp peaks, preventing early-stage policy exploitation of sub-optimal actions. The second one alleviates the estimation bias inherited from offline pretraining by accelerating learning. Extensive experiments on the MuJoco and Adroit environments demonstrate that the proposed method, named SO2, significantly alleviates Q-value estimation issues, and consistently improves the performance against the state-of-the-art methods by up to 83.1%.

On-line temperature-responsive restricted access material of sample preparation technique coupling with liquid chromatography for detection of tetracycline residues in milk

Effort of sample preparation has been working towards the automation and improvement of accuracy. Development of on-line sample preparation coupled with liquid chromatography (LC) is a promising way. In this study, an on-line extraction-LC automated analysis was proposed based on a temperature-sensitive restricted access material (RAM) for the determination of tetracycline residues (TCs) in milk. The RAM was synthesized using silica as substrate by the two-step surface initiated-atom transfer polymerization (SI-ATRP), styrene (St), sodium 4-vinylbenzenesulfonate (Nass) and a lower critical solution temperature (LCST)-responsive n-vinylcaprolactam (VCl) were conjugated to fabricate multiple interaction-adsorption sites of P(St-co-Nass-co-VCl) on silica interior, while an upper critical solution temperature (UCST)-responsive sulfobetaine methacrylate (SBMA) was then block polymerized to form zwitterionic exclusion sites on exterior. Thereafter, the RAM was packed as extraction column to be fixed into LC ahead of C18 analytical column, establishing automatic analysis by rotation of switching valve. In conjunction with LCST and UCST dual-responsive properties to adjust the hydrophobic-hydrophilic transition of the grafted P(St-co-Nass-co-VCl)-b-PSBMA chains, the RAM column acquires the best extraction of TCs and meanwhile the furthest removal of proteins at about 30 ℃ of column temperature. And using the proposed automatic analysis for monitoring of TCs in milk, a wide linearity (20–900 ng mL−1), low limit of detection (1.0 ng mL−1) and limit of quantification (2.5 ng mL−1) as well as good inter-day (<3.9 % RSD) and intra-day precision (<4.8 % RSD) with satisfactory recoveries (97.2–101.9 %) show the superior efficiency. It is believed that the introduction of temperature-sensitive RAM to construct on-line extraction is a powerful tool for detecting trace substances in scientific analyses.

Does source matter? Examining the effects of health experts, friends, and social media influencers on young adult perceptions of Instagram e-cigarette education messages

PurposeYoung adults’ e-cigarette use is a leading public health concern. Using messages from credible sources can help improve message acceptance, yet little research has examined the role of source credibility on young adults’ responses to e-cigarette education messages. MethodsWe examined the impact of source on young adults’ perceptions of e-cigarette education messages and e-cigarettes. In July 2022, we conducted an experimental study using an online sample of young adults (N=459, Mage=24.6) who were randomized to one of three source conditions: expert, friend, or influencer, and viewed e-cigarette education messages. We used one-way ANOVA to estimate the association between the conditions and outcomes (perceived source credibility, message trust, curiosity, use interests, perceived message effectiveness, beliefs, harm perceptions, and intentions to refrain). ResultsThe expert condition was associated with significantly higher perceived source credibility (vs. friend, influencer; p<0.001), message trust (vs. friend, influencer; p<0.001), and curiosity (vs. influencer; p’s<0.05). ConclusionsPublic health campaigns may leverage health experts to deliver e-cigarette education messages targeting young adults to improve effectiveness of the messages.

The phenotype of recovery XI: associations of sleep quality and perceived stress with discounting and quality of life in substance use recovery

PurposeSleep and stress show an interdependent relationship in physiology, and both are known risk factors for relapse in substance use disorder (SUD) recovery. However, sleep and stress are often investigated independently in addiction research. In this exploratory study, the associations of sleep quality and perceived stress with delay discounting (DD), effort discounting (ED), and quality of life (QOL) were examined concomitantly to determine their role in addiction recovery. DD has been proposed as a prognostic indicator of SUD treatment response, ED is hypothesized to be relevant to the effort to overcome addiction, and QOL is an important component in addiction recovery.MethodAn online sample of 118 individuals recovering from SUDs was collected through the International Quit and Recovery Registry. Exhaustive model selection, using the Bayesian Information Criterion to determine the optimal multiple linear model, was conducted to identify variables (i.e., sleep quality, perceived stress, and demographics) contributing to the total variance in DD, ED, and QOL.ResultsAfter model selection, sleep was found to be significantly associated with DD. Stress was found to be significantly associated with psychological health, social relationships, and environment QOL. Both sleep and stress were found to be significantly associated with physical health QOL. Neither sleep nor stress was supported as an explanatory variable of ED.ConclusionTogether, these findings suggest sleep and stress contribute uniquely to the process of addiction recovery. Considering both factors when designing interventions and planning for future research is recommended.

Thinking critically about race bias and culpability perceptions of Latinxs in the criminal justice system

AbstractCritical race theory (CRT) guides insight into structural and institutional discrimination for identifying causes of race disparities in the United States social and political systems. Disparities are pronounced in the criminal justice system (CJS) for Latinx people, and negative attitudes exist about those incarcerated. LatCrit theory promotes an examination of unique issues creating disparities for Latinx people. Given historical, negative stereotypes of Mexican Americans as a criminal type, even exonerees face the taint of criminalization, and this influences perceptions of them. Following LatCrit theory, we examined the relationship between negative Mexican American stereotypes and perceived internal and external culpability with mediation from defendant rights attitudes for a Mexican American exoneree. With data from a national, adult online sample (N = 120), negative stereotypes about Mexican Americans predicted internal culpability with partial mediation from defendant rights beliefs, but the relationship was not found for external culpability. Negative stereotypes were associated with beliefs in the Mexican American exoneree's inherent criminality. With a LatCrit approach, quantitative findings lend insight into the legal decision making process to produce bias. Results highlight the need for continued focus on Latinx people's unique experiences and for change in methods to improve post‐carceral reintegration and eliminate structural and systemic race bias.

Construction of the Views oN Infant Sleep (VNIS) Questionnaire

Parents' beliefs about infant sleep behaviour vary over time and across cultures. No validated instrument exists to understand parents' pre- and postnatal views on infant sleep behaviours, which may influence their caregiving decisions. The Views oN Infant Sleep Questionnaire (VNIS) will be a tool to assess parents' beliefs in order to facilitate tailored perinatal care, increase the reliability of postnatal self-report measures, allow for cross-cultural comparisons, and provide a baseline for researchers to use in longitudinal studies. We recruited an online sample of 971 female participants who were resident in the United Kingdom, at least 28 weeks pregnant, and at least 18 years of age. The initial questionnaire consisted of 31 questions about infant independence, night-waking, infant feeding, touch, and safety, and items were rated on a 5-point Likert scale. The item pool was reduced to 12 using principal component analysis and a structure was found for the three components “Closeness”, “Independence”, and “Night-waking”. Overall, these results suggest that the VNIS can provide a brief scale to measure different aspects of individuals' beliefs about infant sleep. In further research the VNIS needs to be validated with a confirmatory factor analysis in another sample, and to be tested as a cross-cultural instrument.

The SKIN-Q: An Innovative Patient-Reported Outcome Measure for Evaluating Minimally Invasive Skin Treatments for the Face and Body.

Background: As the aesthetics field continues to innovate, it is important that outcomes are carefully evaluated. Objectives: To develop item libraries to measure how skin looks and feels from the patient perspective, that is, SKIN-Q. Methods: Concept elicitation interviews were conducted and data were used to draft the SKIN-Q, which was refined with patient and expert feedback. An online sample (i.e., Prolific) provided field-test data. Results: We conducted 26 qualitative interviews (88% women; 65% ≥ 40 years of age). A draft of the SKIN-Q item libraries were formed and revised with input from 12 experts, 11 patients, and 174 online participants who provided 180 survey responses. The psychometric sample of 657 participants (82% women; 36% aged ≥40 years) provided 713 completed surveys (facial, n = 595; body, n = 118). After removing 14 items, the psychometric analysis provided evidence of reliability (≥0.85) and validity for a 20-item set that measures how skin feels and a 46-item set that measures how skin looks. Short-form scales were tested to provide examples for how to utilize the item sets. Conclusion: The SKIN-Q represents an innovative way to measure satisfaction with skin (face and body) in the context of minimally invasive treatments.

Americans misperceive the frequency and format of political debate

Disagreement over divergent viewpoints seems like an ever-present feature of American life—but how common is debate and with whom do debates most often occur? In the present research, we theorize that the landscape of debate is distorted by social media and the salience of negativity present in high-profile spats. To understand the true landscape of debate, we conducted three studies (N = 2985) across online and lab samples. In contrast to the high-profile nature of negative debates with strangers, we found that people most commonly debate close contacts, namely family members and good friends. In addition, they often report feeling positive after engaging in debate. We then directly measured misperceptions regarding debate in a representative sample of Americans (N = 1991). We found that Americans systematically overestimated how often others engage in debate. This overestimation extended across debate partners (family members, good friends, acquaintances, coworkers, and strangers) and contexts (in-person and online; p’s < 0.001, d’s > 0.98), most strongly overestimating how often Americans debate strangers online. This misprediction may be psychologically costly: overestimating how often Americans debate strangers online significantly predicted greater hopelessness in the future of America. Together, our findings suggest that Americans may experience a false reality about the landscape of debate which can unnecessarily undermine their hope about the future.

Creative Evaluation: The Role of Memory in Novelty & Effectiveness Judgements

ABSTRACT How do we assess the quality of an idea? Current theories suggest that episodic memory contributes to creative ideation, implicating memory retrieval and mental simulation in the generation of creative ideas; however, the role of memory in creative evaluation has not been systematically examined. Across two independent online samples (Study 1 n = 50, Study 2 n = 626), we explore how episodic retrieval supports the evaluation of two distinct aspects of creativity: novelty and effectiveness. In both studies, participants were presented with a series of creative ideas – responses on the alternate uses task – and were asked to independently rate them for novelty/effectiveness. Following each rating, participants were prompted to reflect on their process and type a brief description about how they made their evaluation. We apply computational linguistic analysis to quantify the prevalence of episodic/perceptual details (sights, sounds, etc.) in each evaluation, along with past-focused and future-focused words. Consistent with prior work, we observe a negative correlation (r=-.39) between novelty and effectiveness ratings. Ordinal logistic regression models indicate that perceptual detail and temporal orientation of evaluations are predictive of novelty and effectiveness ratings. We show that people refer more to the past when evaluating familiar, effective ideas; conversely, people refer more to the future when evaluating highly novel, less effective ideas. Overall, these results are consistent with the hypothesis that episodic retrieval supports the evaluation of creative ideas.

Self-perceived stigma in Parkinson’s Disease in an online sample: Comparison with in-person sample, role of anxiety, and relative utility of four measures of stigma perception

Objective Persons with Parkinson’s disease (PwPD) experience motor and non-motor symptoms that may elicit stigmatization. We investigated whether online assessment would replicate in-person findings of younger age and depression as predictors of stigma perception. We further assessed the predictive value of anxiety, and compared predictors across four stigma measures. Methods The online study (n = 347), like the earlier in-person study (n = 362), used the Parkinson’s Disease Questionnaire stigma subscale (PDQ-39stigma). It also assessed anxiety and added the Stigma Scale for Chronic Illness (SSCI), Stigmatization Scale, and Mental Health Consumers’ Experience of Stigma Scale. We correlated stigma perception scores with demographic/clinical characteristics and conducted hierarchical regression and mediation analyses. Results Online and in-person predictors of stigma perception with the PDQ-39stigma included younger age (men) and depression (men, women). Depression mediated the relation between stigma perception and motor experiences of daily living (EDLs). In the online sample, when anxiety was added, it predicted stigma perception (PDQ-39stigma, SSCI) and mediated the relation between stigma and both motor and non-motor EDLs (PDQ-39stigma). For all four stigma-perception scales, younger age predicted scores. Multiple additional predictors of PDQ-39stigma and SSCI scores suggest their utility relative to the other two scales. Conclusions: Younger age and depression predicted self-perceived stigma in online and in-person samples, indicating the cross-modal utility of the measure, PDQ-39stigma. In the online sample, anxiety also predicted stigma perception per the PDQ-39stigma and SSCI. We recommend both measures and note that treating depression and anxiety may be important especially in younger PwPD to reduce self-perceived stigma.

Virtual vs. human influencer: Effects on users’ perceptions and brand outcomes

In the recent wave of artificial intelligence-based innovations, Virtual influencers (VIs) are one of the newest and most promising innovations. Despite their indisputable potential, still little is known about users' reactions to non-human endorsers. Our experimental study investigates users' perceptions of VIs engaged in sponsorship activities on Instagram, examining the impact of the influencer's nature (human vs. virtual) and possible interaction effects of the type of message conveyed (hedonic vs. utilitarian) on the influencer and brand-related variables. In line with the idea that individuals apply human social rules when interacting with computers, as established in the CASA paradigm, our results from an online sample (N = 238) show that disclosing the synthetic nature of a fully anthropomorphized virtual persona does not affect influencer and brand perceptions. Despite virtual influencers' objective lack of capacity to perceive and feel affective and sensorial information, their acceptance by the users is not hindered by an emotion-based communicative style. The research provides social and business implications for companies aiming to implement virtual influencers successfully.
