Show moreKids (and adults) are often curious. Maybe you are curious about dinosaurs, giant squids, or rollercoaster rides. But have you ever been curious about why you are curious about some things but not about other things? In the last 10 years, scientists have asked similar questions about curiosity. In this article, we will share some of the answers. We explain how scientists across the world study curiosity. We also explain that people become curious to seek out specific information or to explore new things. Based on research on curiosity and the brain, scientists think that curiosity is a signal that it is valuable (or rewarding) to learn something or figure something out. Curiosity can even make you remember information better. After reading this article, we hope that your curiosity is satisfied! Show less

Show moreIn the current research we investigated how people deal with decisions in which they have to reject others, something that is unavoidably part of many selection procedures. Integrating insights derived from research on social exclusion and dehumanization, we argued that when people need to reject others, they dehumanize them. To study the association between dehumanization and rejecting in a real-life setting, we conducted two field studies, in which we examined the selection process in student houses, where residents can accept some prospective members, but have to reject others. As predicted, our findings showed that when people need to reject targets, they subtly dehumanize them. Moreover, dehumanizing rejected targets was related to lower rejection aversion. This suggests that when people dehumanize those they have to reject, rejection is easier. Show less

Show moreEpistemic emotions are hardly ever studied together, making it difficult to predict what features are shared versus unique to each emotion. To address this, we conducted two autobiographical recall experiments. We compared awe, surprise, curiosity, interest, confusion, and boredom in terms of elicitors, subjective experience components, and action tendencies. Ratings were analyzed using network analyses, to describe the central features for the whole group of epistemic emotions. In addition, ratings were compared per emotion, to identify key features for each individual emotion. Results showed that valence, arousal, coping potential, and avoidance are central features of all epistemic emotions. Awe, surprise, and interest were relatively positive emotions, which together with curiosity, were associated with arousal, high coping potential, and approach. Confusion and boredom were relatively negative emotions, which were associated with low arousal, low coping potential, and avoidance. Further analyses revealed unique features of (groups of) emotions. For example, awe was associated with exceeded expectancies, while surprise was associated with both exceeded and disconfirmed expectancies. Moreover, curiosity and confusion were associated with having (too) little information, while awe and interest were associated with having sufficient information. All emotions except boredom were associated with exploration, but this was particularly high for curiosity and interest. Show less

Show morePast work suggests that emotion deception in negotiations – communicating a different emotion than experienced – is perceived negatively. We, however, argue that this depends on the type of emotion deception. We compared two emotion deception types – communicating anger while actually being happy, and communicating happiness while being angry – to genuine communications of happiness and anger. In three preregistered experiments (N = 500), participants played the role of employee or supervisor and negotiated with an opponent about salary raises. After their initial offer, participants learned their opponent’s experienced (happiness vs. anger) and communicated emotion (happiness vs. anger). Then, participants made their final demand and reported perceptions of their opponent’s limits and sacrifice. Results showed that participants perceived opponents who communicated genuine anger as having stricter limits and conceded more to them than to opponents using the other emotion communication types. Moreover, opponents who communicated happiness but experienced anger were perceived as making more of a sacrifice than opponents who communicated anger but experienced happiness. In Experiment 3, we also examined effects of emotion deception on non-negotiated outcomes, by assessing the likelihood to hand the opponent a year-end bonus. Participants were most likely to allocate the bonus to opponents that truthfully communicated happiness. Moreover, participants were more likely to allocate the bonus to opponents who communicated happiness but experienced anger than to opponents who communicated anger but experienced happiness. These findings extend social functional accounts of emotion communication, by showing that effects of emotion deception depend on the type of experienced and/or communicated emotions. Show less

Show morePeople experience financial scarcity when they have insufficient financial resources to meet demands, and this experience can affect decision-making in various ways. One proposed consequence of financial scarcity is increased temporal discounting, which is a tendency to value immediate outcomes more strongly than delayed outcomes. To test whether financial scarcity indeed increases temporal discounting, we developed the Household Task—an experimental paradigm during which participants have to manage the finances of a household. In a pilot, we found that manipulating participants’ financial situation in the Household Task (debts vs. savings and control) induced an experience of financial scarcity. Next, Experiments 1 and 2 confirmed that this experience increased temporal discounting of gains and losses. In Experiments 3 and 4, we tested whether experienced scarcity also increases discounting when financial resources were equal between conditions. However, in these experiments, there was no evidence of such an effect. In Experiment 5, we found that discounting increased when available financial resources were constant while expectations about future financial problems might have differed between conditions. In sum, the current research suggests that when experiencing scarcity, discounting increases as a response to a current or anticipated future shortcoming of available financial resources. Yet, there was no evidence suggesting that discounting increases when a scarcity mindset is induced in isolation. Show less

Show moreThe current study investigated the prospective associations between financial scarcity and financial avoidance. We hypothesized that over time, financial scarcity––the experience of lacking needed financial resources––is associated with an increase in financial avoidance––the tendency to avoid dealing with one’s finances––, and vice versa. In a longitudinal panel study, including a large and representative adult sample of Dutch citizens (initial N = 1,122, final N = 837), we measured financial scarcity and financial avoidance twice over a period of 22 months. Data were analyzed using a cross-lagged panel model, which allows to test for prospective effects of one variable on the other, while controlling for autoregressive effects. Confirming our preregistered hypotheses, results showed that financial scarcity was positively related with an increase in subsequent financial avoidance, whereas financial avoidance was positively related with an increase in subsequent financial scarcity. While these longitudinal findings are not causal, they are in line with the concept of a poverty trap, where financial scarcity and financial avoidance form a temporally dynamic and increasing relationship.

Show moreThe current research investigates the effects of exposure to information about the prevalence of sexism in society on women's perceptions, needs, expectations, and career motivation. We propose that such exposure to sexism prevalence may threaten women's fundamental need to belong, and induces perceptions of social exclusion. Study 1 provided correlational evidence that perceiving society as sexist relates to increased perceptions of being excluded. Three experimental studies demonstrated that exposure to information about sexism in the form of fictional research results (Study 2), or actual newspaper articles (Studies 3 and 4), increased women's experiences of social exclusion. Exposure to such information also lowered women's gender-related expectations of achieving their preferred position in society, and reduced career motivation. Together, the article provides insight into the experiential and motivational reactions to sexism in society. Show less

Show moreWe tested whether surprise elicits similar physiological changes as those associated with orienting and freezing after threat, as surprise also involves a state of interruption and attention for effective action. Moreover, because surprise is primarily driven by the unexpectedness of an event, initial physiological responses were predicted to be similar for positive, neutral, and negative surprises. Results of repetition-change studies (4 + 1 in Supplemental Materials) showed that surprise lowers heart rate (Experiments 1-4) and increases blood pressure (Experiment 4). No effects on body movement (Experiment 2) or finger temperature (Experiment 4) were found. When unexpected stimuli were presented more often (making them less surprising) heart rate returned to baseline, while blood pressure remained high (Experiment 4). These effects were not influenced by stimulus valence. However, second-to-second analyses within the first (surprising) block showed a tendency for a stronger increase in systolic blood pressure after negative vs. positive surprise. Show less

Show moreWhile a considerable body of literature has shown that leaving one's group is a negative experience that people tend to avoid, the current research focuses on the idea that on some occasions, leaving one's group can come with positive consequences. Across four experimental studies, we demonstrate that people's reactions to staying in versus leaving their group are modulated by their performance. Studies 1 and 2 showed that performing considerably below (vs. at the same level as) one's group members, can be an aversive experience that people prefer to avoid, even when this means being excluded by their fellow group members. Exclusion harmed low-performers' and equal-performers' feelings and need fulfilment equally, but low-performers still considered exclusion relatively relieving and preferable. They also experienced inclusion in the group as less positive than equal-performers. Studies 3 and 4 showed that low-performing participants were also relatively likely to leave the group when they had the chance. Although this resulted in participants' separation from the group, this had positive effects for them, as it restored their fundamental needs and improved their feelings, relative to when they were still part of the group.

Show moreControl is a fundamental motive in people’s lives and previous research converges on the notion that lack of control is aversive because it undermines epistemic beliefs in the nonrandomness of the world. A key motivation underlying control is therefore the need to perceive the world as structured. However, strong individual dif-ferences exist in the extent to which people need structure. Based on this, we reasoned that if structure is indeed a key motive underlying control motivation, instances of low control should be more impactful for people with a high need for structure. We tested this logic in three studies. Results confirmed that participants with high personal need for structure evaluated a control-threat as more important and more negative than those with low personal need for structure. Need for structure did not impact evaluations of instances of control-affirmation. The current research shows that control is indeed important, but even more so for people with a high need for structure. Show less

Show moreCuriosity is evoked when people experience an information-gap between what they know and what they do not (yet) know. Curious people are motivated to find the information they are missing. This motivation has different components: People want to reduce the uncertainty of not knowing something (deprivation motive) and they want to discover new information to expand their knowledge (discovery motive). We discuss recent research that shows that the affective experience of curiosity is the result of the relative strength of the deprivation and discovery motives. This, in turn, is contingent on individual differences, anticipated features of the actual target, and features of the information-gap. Show less

Show moreIt is well documented that when people (targets) are socially excluded by others (actors) they feel hurt. To understand social exclusion, however, we argue it is crucial to look not only at the end state of exclusion (do targets end up excluded or included?) but also at the process (how are targets excluded?). In four studies we differentiated between two processes of exclusion: being removed from a group and being denied access into a group. Results indicate that actors' exclusion behavior was influenced by the process: Actors were more likely to deny others access into the group than to remove members from the group. The data suggest that actors may do so because they consider inclusion of group members to be the norm, while group norms do not prescribe the inclusion of prospective members. For targets being denied access and being removed from a group was equally distressing. We conclude that the process of exclusion is critical to understand when actors exclude others, but does not affect excluded targets' feelings. Show less

Show moreFreezing is an adaptive defensive response to a stressful event. Recent research suggests that freezing not only occurs in response to physical threats but also in response to social threats (e.g., angry faces; Roelofs et al. in Psychol Sci 21:1575–1581, 2010). Given the practical and theoretical importance of this finding, the current study aimed to replicate and extend it. Following the original study, we measured heart rate while participants viewed emotional faces (angry, happy, neutral). Extending the original study, we included a baseline measure and performed additional, more fine-grained analyses. Our results support the hypothesis that participants show physiological signs of freezing when looking at angry faces. Importantly, we also find this effect when comparing heart rate in the angry block to baseline levels. Interestingly, the heart rate effects are explained by deceleration in the first 30 s of the 1-min angry block, but not in the second 30 s. Like Roelofs et al., we find evidence that the effects are modulated by state anxiety, but our effects are only marginal and we do not replicate the negative correlation between heart rate and state anxiety in the angry block. In general, we thus find evidence for physiological signs of freezing in response to social threat. We discuss implications and venues for future research. Show less

Show moreResearch into green advertising has mainly investigated how green appeals can enhance product attitudes, sales, and brand image. But what happens after people have purchased a ‘green’ product advertised in a green ad? In two experiments, we show that purchasing a green product may have paradoxical post-purchase effects, such that it may lower intentions to engage in subsequent environmentally friendly behaviour (a so-called licensing effect). Importantly, our results show that these post-purchase effects are moderated by environmental identity: only people with a weak environmental identity show these paradoxical postpurchase licensing effects, people with a strong environmental identity are more likely to continue behaving in an environmentally friendly way.

Show moreResponses to surprising events are dynamic. We argue that initial responses are primarily driven by the unexpectedness of the surprising event and reflect an interrupted and surprised state in which the outcome does not make sense yet. Later responses, after sense-making, are more likely to incorporate the valence of the outcome itself. To identify initial and later responses to surprising stimuli, we conducted two repetition-change studies and coded the general valence of facial expressions using computerised facial coding and specific facial action using the Facial Action Coding System (FACS). Results partly supported our unfolding logic. The computerised coding showed that initial expressions to positive surprises were less positive than later expressions. Moreover, expressions to positive and negative surprises were initially similar, but after some time differentiated depending on the valence of the event. Importantly, these patterns were particularly pronounced in a subset of facially expressive participants, who also showed facial action in the FACS coding. The FACS data showed that the initial phase was characterised by limited facial action, whereas the later increase in positivity seems to be explained by smiling. Conceptual as well as methodological implications are discussed. Show less

Show moreResearch shows that people search for balance in their moral (e.g., environmentally friendly) behaviors such that they feel licensed to behave less morally after a previous moral act (licensing) and cleanse previous morally questionable behaviors by subsequently behaving more morally (cleansing). This article investigates whether this balancing may extend to close others, but not to nonclose others, and tests vicarious licensing and cleansing in the environmental domain. Study 1 showed that vicarious licensing effects are more likely when a close other displayed environmentally friendly (vs. neutral) behavior. Study 2 showed that environmental vicarious licensing effects are more likely for close than nonclose others. Studies 3 and 4 suggested that vicarious licensing effects, but not vicarious cleansing effects are more likely for close (vs. nonclose) others. Finally, a meta-analysis showed that overall these studies provide evidence for vicarious licensing effects, but not for vicarious cleansing effects in the environmental domain. Show less

Show moreDijksterhuis and van Knippenberg (1998) reported that participants primed with a category associated with intelligence (“professor”) subsequently performed 13% better on a trivia test than participants primed with a category associated with a lack of intelligence (“soccer hooligans”). In two unpublished replications of this study designed to verify the appropriate testing procedures, Dijksterhuis, van Knippenberg, and Holland observed a smaller difference between conditions (2%–3%) as well as a gender difference: Men showed the effect (9.3% and 7.6%), but women did not (0.3% and −0.3%). The procedure used in those replications served as the basis for this multilab Registered Replication Report. A total of 40 laboratories collected data for this project, and 23 of these laboratories met all inclusion criteria. Here we report the meta-analytic results for those 23 direct replications (total N = 4,493), which tested whether performance on a 30-item general-knowledge trivia task differed between these two priming conditions (results of supplementary analyses of the data from all 40 labs, N = 6,454, are also reported). We observed no overall difference in trivia performance between participants primed with the “professor” category and those primed with the “hooligan” category (0.14%) and no moderation by gender.

Show moreComplex novelty like new technologies can be exciting in terms of promising possibilities, but people might also feel that they do not exactly grasp its meaning or purpose. We argue that to become interested in complex novelty, it is key that people have a sense that they can cope with it. In three experiments we showed that people who have relatively high coping potential are more interested in complex novelty than people who have relatively low coping potential. Specifically, interest in complex novel products and inventions increased after increasing product-specific understanding (Experiments 1 and 2) and after inducing a more general state in which people can tolerate complex novelty (Experiment 3). Theoretical and practical implications are discussed. Show less
