RESUMO

BACKGROUND: People's perceived risk of being infected and having severe illness was conceived as a motivational source of adherence to behavioral measures during the COVID-19 crisis. METHODS: We used online self-reported data, spanning 20 months of the COVID-19 crisis in Belgium (n = 221,791; 34.4% vaccinated; July 2020 - March 2022) to study the association between risk perception and motivation. RESULTS: Both perceived infection probability and severity fluctuated across time as a function of the characteristics of emerging variants, with unvaccinated persons perceiving decreasingly less risk compared to vaccinated ones. Perceived severity (and not perceived probability) was the most critical predictor of autonomous motivation for adherence to health-protective measures, a pattern observed at both the between-day and between-person level among both vaccinated and unvaccinated individuals. An integrated process model further indicated that on days with higher hospitalization load, participants reported being more adherent because risk severity and autonomous motivation for adherence were more elevated on these days. CONCLUSIONS: These findings suggest that risk severity served as a critical and dynamic resource for adherence to behavioral measures because it fostered greater autonomous regulation.

RESUMO

Crises in science concern not only methods, statistics, and results but also, theory development. Beyond the indispensable refinement of tools and procedures, resolving crises would also benefit from a deeper understanding of the concepts and processes guiding research. Usually, theories compete, and some lose, incentivizing destruction of seemingly opposing views. This does not necessarily contribute to accumulating insights, and it may incur collateral damage (e.g., impairing cognitive processes and collegial relations). To develop a more constructive model, we built on adversarial collaboration, which integrates incompatible results into agreed-on new empirical research to test competing hypotheses [D. Kahneman, Am. Psychol. 58, 723-730 (2003)]. Applying theory and evidence from the behavioral sciences, we address the group dynamic complexities of adversarial interactions between scientists. We illustrate the added value of considering these in an "adversarial alignment" that addressed competing conceptual frameworks from five different theories of social evaluation. Negotiating a joint framework required two preconditions and several guidelines. First, we reframed our interactions from competitive rivalry to cooperative pursuit of a joint goal, and second, we assumed scientific competence and good intentions, enabling cooperation toward that goal. Then, we applied five rules for successful multiparty negotiations: 1) leveling the playing field, 2) capitalizing on curiosity, 3) producing measurable progress, 4) working toward mutual gain, and 5) being aware of the downside alternative. Together, these guidelines can encourage others to create conditions that allow for theoretical alignments and develop cumulative science.

RESUMO

This vignette-based study examined in a sample of unvaccinated Belgian citizens (N = 1918; Mage = 45.99) how health care workers could foster reflection about and intentions to get vaccinated against COVID-19 by experimentally varying their communication style (i.e., autonomy-supportive vs. controlling) and the reference to external motivators (i.e., use of a monetary voucher or corona pass vs. the lack thereof). Each participant was randomly assigned to one of six conditions and rated a vignette in terms of anticipated autonomy satisfaction, perceived effectiveness, reflection, and vaccination intention. An autonomy-supportive, relative to a controlling, communication style predicted greater autonomy need satisfaction, which in turn related positively to perceived effectiveness, reflection, and vaccination intention. External motivators failed to generate positive effects compared to the control condition. The findings highlight the critical role of autonomy support in promoting a self-endorsed decision to get vaccinated.

RESUMO

How one approaches gender differences in general likely influences the way one handles mixed-gender negotiations. In the present paper, we examine general beliefs on how women negotiators do-as opposed to how they "should"-handle gender in order to increase their chances of success. First, we hypothesised that people's general beliefs would support a sexblindness ideology according to which gender is, and indeed should be, ignored in order to succeed. Second, because negotiation comes across as a stereotypically masculine activity, we predicted that prescriptions regarding what women should do to succeed would commonly favour assimilationism (the belief that women need to assimilate to male norms) over sexawareness (the belief that gender differences should be acknowledged and celebrated). We nevertheless predicted a general belief that women might stay away from these prescriptions and rely more on their gender (i.e. endorse sexawareness over assimilationism) within feminine as compared to masculine and neutral-topic negotiations. Together, our two experiments confirm these predictions. We discuss our results in terms of the consequences on women's gender ideology-based strategies, a potentially relevant aspect to their actual negotiating outcomes.

RESUMO

Brinkman et al. (2019) recently introduced an innovative metric-infoVal-to assess the informational value of classification images (CIs) relative to a random distribution. Although this measure constitutes a valuable tool to distinguish random from nonrandom CIs, we identified two noteworthy discrepancies between the mathematical formalization of the infoVal metric and the authors' computation. Specifically, the computation was based on the one norm instead of the Euclidean norm, and the k constant was omitted in the denominator of the ratio that produces infoVal. Accordingly, the simulations and experimental results reported by Brinkman et al. do not build on the correct infoVal computation but on a biased index. Importantly, this discrepancy in the computation affects the statistical power and Type I and error rate of the metric. Here we clarify the nature of the discrepancies in the computation and run Brinkman et al.'s Simulation 1 anew with the correct values, to illustrate their consequences. Overall, we found that relying on the miscomputed infoVal metric can lead to misguided conclusions, and we urge researchers to use the correct values.

RESUMO

One of the two miscomputations identified in the infoVal metric, namely the omission of the k constant, turns out not to be a miscomputation, since the constant was already taken into account by default in the mad() function from R (see https://www.rdocumentation.org/packages/stats/versions/3.6.2/topics/mad ).

RESUMO

Previous research indicates that meta-stereotypes are predominantly negative. However, the valence of the meta-stereotypes may not be the only factor accounting for the detrimental effects associated with their activation. In addition to valence, we propose that the subjective difficulty of retrieving the meta-stereotype might critically determine whether its activation deteriorates intergroup orientations. An experimental study showed that the effect of the meta-stereotype activation on the desire to interact with outgroup members was moderated by the interaction between the valence of the meta-stereotype and its difficulty of retrieval. In particular, the activation of a positive meta-stereotype deteriorated intergroup orientations when the difficulty of retrieval was high as compared with a condition in which the difficulty of retrieval was low. In sharp contrast, the activation of a negative meta-stereotype worsened intergroup orientations when the difficulty of retrieval was low as compared with a condition in which the difficulty of retrieval was high.

RESUMO

Group-based emotions are emotional reactions to group concerns and have been shown to emerge when people appraise events while endorsing a specific social identity. Here we investigate whether discussing a group-relevant event with other group members affects emotional reactions in a similar way. In two experiments, we confronted participants with an unfair group-relevant event, while manipulating their social identity and whether they discussed the event or an unrelated topic. Our major finding is that having group members discuss the unfair group-relevant event led to emotions that were more negative than in the irrelevant discussion and comparable to those observed when social identity had been made salient explicitly beforehand. Moreover, it also generated group-based appraisals of injustice (Experiment 1) and group-based identity (Experiment 2). This research sheds new light not only on the consequences of within-group sharing of emotions for the unfolding of intergroup relations but also on the nature of group-based emotions.

RESUMO

This article provides a review of past and contemporary debates regarding the role of awareness in attitude formation through evaluative conditioning (EC), that is, by repeatedly pairing a stimulus with other stimuli of positive or negative valence. Because EC is considered the most prototypical method to form and change the network of evaluative associations in memory, the role of awareness in this effect is critical to the question of whether attitudes may be formed and changed through dual processes. We analyze the reasons why there has been so much discussion and disagreement regarding the role of awareness, review past and contemporary methodologies and their limitations, discuss the role of mental processes and conditioning procedures, and identify promising directions for future research in this area.

RESUMO

We argue (1) that the empirical evidence offered by the authors is insufficient to sustain their claim; (2) that, beyond methodological problems, the proposed underlying cognitive mechanism is largely speculative and that a reverse, more motivational, path is equally plausible; and (3) that the distinction and antecedence of inherence intuitions with respect to essentialist beliefs remain to be demonstrated.

RESUMO

We reconcile interactive and additive models of category intersection by recasting these theoretical efforts within the conceptual combination framework. In three studies (Ntot = 364), we showed that, in line with an interactive approach, combining 'elderly men' with 'gay men' generated an atypical subtype with unique attributes that could not be reduced to the sum of the attributes of the constituent categories (Studies 1-3). Moreover, consistent with the additive models, combining 'heterosexual men' with age categories (i.e. young/elderly men, Study 1) made their age typicality particularly salient, and 'young men' with sexual orientation categories (i.e. gay/heterosexual men, Study 2) emphasized their sexual orientation typicality. Also, participants not only appraised 'gay men' and 'young gay men' in part as redundant categories, but they also judged 'elderly men' and 'elderly heterosexual men' to be largely overlapping. These findings take advantage of a multi-method assessment, spanning from measures of perceived typicality to the analysis of attributes freely generated in reaction to the target categories. Our results inform cognitive models of multiple category combinations and shed light on the cognitive 'invisibility' of elderly gay men and its social implications.

RESUMO

We investigate how the complexity of the social environment (more vs. less groups) influences attitude formation. We hypothesize that facing a larger number of groups renders learning processes about these groups noisier and more regressive, which has two important implications. First, more-complex social environments should lead perceivers to underestimate actual group differences. Second, because most people usually behave positively, more-complex social environments produce negatively biased attitudes and cause perceivers to overestimate the frequency of "negative" individuals among groups. We tested these predictions in five attitude formation experiments (N=2,414). Participants' attitudes and learned base rates of positive and negative group members proved more regressive in complex social environments, that is, with multiple groups, compared with less-complex environments, that is, with fewer groups. In a predominantly positive social environment, this regression caused participants to form more negative group attitudes and more strongly overestimate negative individuals' prevalence among groups.

RESUMO

Previous research shows that stereotypes can distort the visual representation of groups in a top-down fashion. In the present endeavor, we tested if the compensation effect-the negative relationship that emerges between the social dimensions of warmth and competence when judging two social targets-would bias the visual representations of these targets in a compensatory way. We captured participants' near spontaneous facial prototypes of social targets by means of an unconstrained technique, namely the reverse correlation. We relied on a large multi-phase study (N = 869) and found that the expectations of the facial content of two novel groups that differed on one of the two social dimensions are biased in a compensatory manner on the facial dimensions of trustworthiness, warmth, and dominance but not competence. The present research opens new avenues by showing that compensation not only manifests itself on abstract ratings but that it also orients the visual representations of social targets.

RESUMO

Group-based emotions have been conceptualised as being rooted in perceivers' social identity. Consistent with this idea, previous research has shown that social identity salience affects group-based emotions, but no research to date has directly examined the role of group-based appraisals in comparison with individual appraisals. In the present studies, we measured group-based appraisals through a thought-listing procedure. In Experiment 1, we explicitly reminded people of their group identity, which led to the predicted change in group-based anger. This effect was mediated by group-based appraisals. In Experiment 2, participants either discussed a group-relevant scenario in small groups or a related topic irrelevant to the group. The group-relevant condition not only led to stronger indignation but the perceived presence of group-based appraisals was also related to participants' reports of indignation. These results provide further evidence for the importance of group-based appraisals as components of group-based emotions.

RESUMO

To limit the spread of COVID-19, public authorities have recommended sanitary behaviors such as handwashing, mask-wearing, physical distancing, and social distancing. We recruited a large sample of higher education students in Belgium (N = 3201-3441) to investigate the role of sociodemographic variables, mental health, previous COVID-19 infections, academic involvement, and risk perception on adherence to these sanitary behaviors. This cross-sectional study took place during the second COVID-19 wave in Belgium, between February and March 2021. Analyses showed that living alone, being female, later in the academic curriculum, having higher general and health anxiety, higher academic involvement, and higher risk perception were positively associated with adherence to the four aforementioned sanitary behaviors. Conversely, previous infection with COVID-19 and having been quarantined were negative predictors. Our results show a set of predictors highly similar for the four sanitary behaviors. We discuss potential initiatives to increase adherence to sanitary behaviors in this group of highly educated youngsters.

RESUMO

OBJECTIVE: Across nationwide rollout of COVID-19 vaccination, people in Belgium differed widely in their vaccination intention. In the present study, we examined (a) how people's vaccination intentions changed during the vaccination rollout and (b) whether changes in motivation (i.e., autonomous, controlled, and distrust-based (a)motivation) predicted changes in vaccination intention, thereby taking into account people's vaccination intention at baseline. METHOD: Using 4 subsamples of participants who were vaccinated at different time points (ntotal = 10,799) between December 2020 and June 2021; we used latent change modeling and latent growth curve modeling to examine the associations among initial levels and changes in vaccination motivation and vaccination intention. RESULTS: Across subsamples, changes in vaccination intention were found to be qualified by changes in motivation. An increase in autonomous motivation was related to a positive shift in vaccination intention, while an increase in both controlled motivation and distrust-based amotivation was related to a negative shift in vaccination intention. Moreover, autonomous motivation predicted especially an increase in vaccination intention among those initially low in vaccination intention, whereas an increase in either controlled motivation or distrust-based amotivation especially predicted a decrease in vaccination intention among those initially high in vaccination intention. CONCLUSIONS: Findings suggest that a growing sense of ownership and a reduction in distrust is critical for individuals to develop a stronger intention to get vaccinated, particularly when people had initially low vaccination intentions. We discuss conceptual, methodological, and practical implications. (PsycInfo Database Record (c) 2023 APA, all rights reserved).

RESUMO

The transmissibility of new COVID-19 variants and decreasing efficacy of vaccines led authorities to recommend a booster and even an annual dose. However, people's willingness to accept new doses varied considerably. Using two independent longitudinal samples of 4596 (Mean age = 53.6) and 514 (Mean age = 55.9) vaccinated participants, we examined how people's (lack of) vaccination motivation for their first dose was associated with their intention to get a booster (Sample 1) and an annual dose (Sample 2) several months later (Aim 1). We also aimed to capture the impact of the motivational heterogeneity on these intentions by capitalizing on participants' different motivational profiles collected at baseline (Aim 2). Across both samples, autonomous motivation, controlled motivation, and distrust-based amotivation were uniquely related to, respectively, higher, lower, and even lower booster and annual dose intentions. Further, a two-step clustering procedure revealed five profiles, with the profiles characterized by higher autonomous motivation (i.e. Good Quality and High Quantity profiles) reporting the highest vaccination intentions and the profile characterized by the highest number of obstacles (i.e. Global Amotivated profile) yielding the lowest vaccination intentions. These results stress the critical need to support citizens' volitional endorsement of vaccination to harvest long-term benefits with respect to COVID-19.

RESUMO

The essential role of the psychological needs for autonomy, competence, and relatedness in well-being has been demonstrated convincingly. Yet whether their fulfillment also serves as a source of resilience in the face of adversity has received limited attention. A longitudinal sample of Belgian citizens (N = 1869; Mage = 56.23, 68% female) completed an online questionnaire on 13 occasions between April 2020 and April 2022 during the COVID-19 crisis. Multilevel analyses showed that need fulfillment, both at the between- and within-person level, related negatively to concerns, even after controlling for exposure to personal risks. Further, the association between concerns and changes in symptoms of depression and anxiety was dampened when people reported higher need fulfillment compared with others (i.e. between-person level) or when they reported periodically more need fulfillment than usual (i.e. within-person level). This moderation effect occurred on top of the systematic negative main effect of need fulfillment on symptoms of anxiety and depression. Psychological need fulfillment serves as a resilience factor (a) by reducing concerns in the face of adverse events (i.e. an appraisal effect) and (b) by mobilizing resources that help individuals to deal better with concerns (i.e. a coping effect). Theoretical and practical implications of the resilience effect of need fulfillment are discussed.

RESUMO

BACKGROUND: The stringency of the measures taken by governments to combat the COVID-19 pandemic varied considerably across countries and time. In the present study, we examined how the proportionality to the epidemiological situation is related to citizens'behavior, motivation and mental health. METHODS: Across 421 days between March 2020 and March 2022, 273,722 Belgian participants (Mage = 49.47; 63.9% female; 33% single) completed an online questionnaire. Multiple linear mixed regression modeling was used to examine the interaction between the epidemiological situation, as indicated by the actual hospitalization numbers, and the stringency index to predict day-to-day variation in the variables of interest. RESULTS: Systematic evidence emerged showing that disproportional situations, as opposed to proportional situations, were associated with a clear pattern of maladaptive outcomes. Specifically, when either strict or lenient measures were disproportional in relation to the epidemiological situation, people reported lower autonomous motivation, more controlled motivation and amotivation, less adherence to sanitary rules, higher perceived risk of infection, lower need satisfaction, and higher anxiety and depressive symptoms. Perceived risk severity especially covaried with the stringency of the measures. At the absolute level, citizens reported the highest need satisfaction and mental health during days with proportional lenient measures. CONCLUSION: Stringent measures are not per se demotivating or compromising of people's well-being, nor are lenient measures as such motivating or enhancing well-being. Only proportional measures, that is, measures with a level of stringency that is aligned with the actual epidemiological situation, are associated with the greatest motivational, behavioral, and mental health benefits.

RESUMO

This study examined the contribution of social anxiety to the evaluation of emotional facial stimuli, while controlling for the gender of participants and stimuli. Participants (n=63) completed two tasks: a single face evaluation task in which they had to evaluate angry versus neutral faces and, a facial crowd evaluation task in which they had to evaluate displays with a varying number of neutral and angry faces. In each task, participants had to evaluate the stimuli with respect to (a) the degree of disapproval expressed by the single face/crowd, and (b) the perceived difficulty of interacting with the face/crowd (emotional cost). Consistent with earlier studies, results showed that social anxiety modulated the evaluation of single faces for emotional cost, but not for disapproval ratings. In contrast, the evaluation of facial crowds was modulated by social anxiety on both ratings.
