Biased assimilation is the tendency to evaluate belief‐consistent information more positively than belief‐inconsistent information. Previous research has demonstrated that biased assimilation is due to an inconsistency between an argument and the recipient's position toward this argument. The present research revealed that an inconsistency between a source's position (independently of the argument) and the recipient's position is also responsible for biased assimilation. In two studies, participants evaluated arguments stated by a politician. Party affiliation of the politician was correctly labeled, incorrectly labeled, or not labeled. The politicians' arguments were evaluated more favorably by their respective voters when party affiliation was correctly labeled. This biased evaluation diminished when party affiliation was not labeled and even slightly reversed when party affiliation was incorrectly labeled.

In five studies we show that the introduction of the Euro influences price estimations and the perception of salaries among people in Germany. People confronted with wages given in Euros compared to the German Mark (DM) showed a reduced willingness to face long distances to get to work when accepting a job offer. When asked to price various consumer goods appropriately, they estimated higher prices if they used the ‘Euro’ currency compared to price estimations made in DM. This phenomenon only occurred with regard to the Euro, but not in comparison with other currencies (cf. the British Pound and Austrian Schilling). The differing price estimations between the Euro and the German Mark were not influenced by participants' attitude towards the Euro. Moreover, it turned out that they depended on how the judgement context was framed. Only if participants expected to make price estimations for shops in their home country, Germany, did the familiar nominal DM figures serve as an anchor heightening the estimated prices in Euro. The same effect disappeared if participants were instructed to make their price estimations for shops in a foreign country (Ireland). Copyright © 2002 John Wiley & Sons, Ltd.  相似文献

Concurrent tasks, such as articulatory suppression and manual tapping, are used to understand the mechanisms underlying short-term memory by overloading domain-specific resources. The present study addresses the debate regarding the theoretical frameworks accounting for interference in serial recall by comparing the effects of both the modality of concurrent tasks (verbal vs. spatial) as well as the state of the tasks (steady vs. changing) in both verbal and spatial recall. The findings indicate that the verbal changing-state concurrent task significantly impaired digit recall, whereas the spatial changing-state concurrent task significantly impaired block recall. The theoretical implications are discussed in the context of a multimodal working memory model with domain-specific resources and a unitary approach to short-term memory.  相似文献

On Facebook, connections between users are published within “friends” lists. Therefore, ties between in- and outgroup members may be easily observed. We simulated this novel form of indirect intergroup contact through an evaluative conditioning (EC) procedure and tested if intergroup attitudes may be influenced positively. To be specific, we presented outgroup members as conditioned stimuli (CSs) and mutual friendship as positively valenced unconditioned stimulus (US). To test our hypotheses, we carried out eight studies measuring explicit and implicit attitudes as well as prosocial intentions toward a target outgroup. However, results demonstrate consistently that the EC procedure did not improve attitudes.  相似文献

The present research examined the effects of social exclusion on ethnocentrism. It was reasoned that expressions of ethnocentrism boost one's social identity, which can serve as a buffer to the thwarted need to belong. In fact, Study 1 revealed that social exclusion, relative to a neutral control condition, increased participant's expressions of ethnocentrism. A second study replicated this finding and showed that social exclusion experiences also increase ethnocentrism relative to a social acceptance and a negative, non-rejection condition. These findings suggest that the effects of social exclusion on ethnocentrism are specific to the thwarted need to belong.  相似文献

Multilevel structural equation models are increasingly applied in psychological research. With increasing model complexity, estimation becomes computationally demanding, and small sample sizes pose further challenges on estimation methods relying on asymptotic theory. Recent developments of Bayesian estimation techniques may help to overcome the shortcomings of classical estimation techniques. The use of potentially inaccurate prior information may, however, have detrimental effects, especially in small samples. The present Monte Carlo simulation study compares the statistical performance of classical estimation techniques with Bayesian estimation using different prior specifications for a two-level SEM with either continuous or ordinal indicators. Using two software programs (Mplus and Stan), differential effects of between- and within-level sample sizes on estimation accuracy were investigated. Moreover, it was tested to which extent inaccurate priors may have detrimental effects on parameter estimates in categorical indicator models. For continuous indicators, Bayesian estimation did not show performance advantages over ML. For categorical indicators, Bayesian estimation outperformed WLSMV solely in case of strongly informative accurate priors. Weakly informative inaccurate priors did not deteriorate performance of the Bayesian approach, while strong informative inaccurate priors led to severely biased estimates even with large sample sizes. With diffuse priors, Stan yielded better results than Mplus in terms of parameter estimates.  相似文献

A correlational study on Facebook investigated the relationship between virtual intergroup contact and general attitudes toward diverse out‐groups. A so‐called Facebook application retrieved objective data about the intercultural composition of participants' Facebook networks. The exact percentage of out‐group friends correlated significantly with more favorable out‐group attitudes. This relationship was mediated by humanitarian‐egalitarian values, suggesting that having intercultural friends on Facebook is positively linked to value orientations, which in turn are associated with more favorable intergroup attitudes. In addition, identification with one's own national group and real‐life experience abroad did not moderate the results. Overall, although causation cannot be inferred because of the correlational design of our study, results suggest that virtual intergroup contact may positively affect attitudes.  相似文献

We propose a unified theory of intentions as neural processes that integrate representations of states of affairs, actions, and emotional evaluation. We show how this theory provides answers to philosophical questions about the concept of intention, psychological questions about human behavior, computational questions about the relations between belief and action, and neuroscientific questions about how the brain produces actions. Our theory of intention ties together biologically plausible mechanisms for belief, planning, and motor control. The computational feasibility of these mechanisms is shown by a model that simulates psychologically important cases of intention.  相似文献

Reading others' emotional body expressions is an essential social skill. Adults readily recognize emotions from body movements. However, it is unclear when in development infants become sensitive to bodily expressed emotions. We examined event‐related brain potentials (ERPs) in 4‐ and 8‐month‐old infants in response to point‐light displays (PLDs) of happy and fearful body expressions presented in two orientations (upright and inverted). The ERP results revealed that 8‐month‐olds but not 4‐month‐olds respond sensitively to the orientation and the emotion of the dynamic expressions. Specifically, 8‐month‐olds showed (i) an early (200–400 ms) orientation‐sensitive positivity over frontal and central electrodes, and (ii) a late (700–1100 ms) emotion‐sensitive positivity over temporal and parietal electrodes in the right hemisphere. These findings suggest that orientation‐sensitive and emotion‐sensitive brain processes, distinct in timing and topography, develop between 4 and 8 months of age.  相似文献
