Belief Change as Propositional Update

This study examines the problem of belief revision, defined as deciding which of several initially accepted sentences to disbelieve, when new information presents a logical inconsistency with the initial set. In the first three experiments, the initial sentence set included a conditional sentence, a non-conditional (ground) sentence, and an inferred conclusion drawn from the first two. The new information contradicted the inferred conclusion. Results indicated that conditional sentences were more readily abandoned than ground sentences, even when either choice would lead to a consistent belief state, and that this preference was more pronounced when problems used natural language cover stories rather than symbols. The pattern of belief revision choices differed depending on whether the contradicted conclusion from the initial belief set had been a modus ponens or modus tollens inference. Two additional experiments examined alternative model-theoretic definitions of minimal change to a belief state, using problems that contained multiple models of the initial belief state and of the new information that provided the contradiction. The results indicated that people did not follow any of four formal definitions of minimal change on these problems. The new information and the contradiction it offered was not, for example, used to select a particular model of the initial belief state as a way of reconciling the contradiction. The preferred revision was to retain only those initial sentences that had the same, unambiguous truth value within and across both the initial and new information sets. The study and results are presented in the context of certain logic-based formalizations of belief revision, syntactic and model-theoretic representations of belief states, and performance models of human deduction. Principles by which some types of sentences might be more “entrenched” than others in the face of contradiction are also discussed from the perspective of induction and theory revision.     

Effect of body size on aggression in the ant,Cataglyphis niger (Hymenoptera; Formicidae)

In polymorphic ants, such as Cataglyphis niger, sterile individual workers from the same nest show some degree of variation in size and/or morphology. We studied whether worker size and size difference between opponents had an effect on aggression during conspecific encounters. Although the capacity to recognize nestmates was shared by all individuals, some patterns of agonistic behaviors were size related. Escape was mostly displayed by the small workers, and threat, associated with ritualized fights, by the large workers. As game theory predicted, ants of C. niger adjusted their level of aggression as a function of the size of the opponent. However, only large individuals used such assessment strategies, responding with escalation of aggression towards small workers and reduction of aggression towards large ones. On the contrary, small individuals behaved in the same manner whatever the opponent's size. Differences between both morphological castes were discussed with reference to the resource holding assessment models. Aggr. Behav. 25:369–379, 1999. © 1999 Wiley‐Liss, Inc.     

Support for collective action against refugees: The role of national,European, and global identifications,and autochthony beliefs

To understand recent anti-refugee protests in Europe, we examined how different levels of inclusiveness of group identities (national, European, and global) are related to intentions to protest among native Europeans. We focused on the mediating role of autochthony (a belief that the first inhabitants of a territory are more entitled) and the moderating role of threat. Survey data from 11 European countries (N = 1,909) showed that national identification was positively associated with autochthony, and therefore, with the intention to protest against refugees. In contrast, global identification was related to lower protest intentions via lower autochthony. These paths were found only among Europeans who perceived refugees as a threat. European identification was not related to the endorsement of autochthony or to collective action. These findings indicate why and when majority members are willing to participate in collective action against refugees, and underscore the importance of global identification in the acceptance of refugees.     

Evaluations versus stereotypes in emotion recognition: a replication and extension of Craig and Lipp’s (2018) study on facial age cues

Recently, Cognition and Emotion published an article demonstrating that age cues affect the speed and accuracy of emotion recognition. The authors claimed that the observed effect of target age on emotion recognition is better explained by evaluative than stereotype associations. Although we agree with their conclusion, we believe that with the research method the authors employed, it was impossible to detect a stereotype effect to begin with. In the current research, we successfully replicate previous findings (Study 1). Furthermore, by changing the comparative context, Study 2 provides a first test of age-stereotypes affecting emotions recognition. We discuss recommendations for future studies in the domain of social categorisation and emotion recognition.     

Voting “Against Islamization”? How Anti‐Islamic Right‐Wing,Populist Political Campaign Ads Influence Explicit and Implicit Attitudes Toward Muslims as Well as Voting Preferences

We explore the effects of anti‐Islamic right‐wing, populist political campaign ads on voting intention for a right‐wing populist party using a quota‐based online experiment (N = 174). Additionally, we investigate implicit attitudes (i.e., automatic affective associations) and explicit attitudes (i.e., overtly expressed evaluations) toward Muslims as underlying mechanisms of these effects. We find that exposure to the political campaign ads prompts explicit hostile attitudes toward Muslims mediated by implicit attitudes. Explicit attitudes in turn shape voting intention. Moreover, implicit attitudes toward Muslims predict voting preference beyond the influence of explicit attitudes. Thus, resentments toward Muslims may foster voters’ support for anti‐Islamic right‐wing populist parties even “under the radar” of conscious awareness. In sum, this study demonstrates for the first time the entire process of right‐wing, populist political campaign ads’ effects on voting preferences via implicit and explicit attitudes toward Muslims.     

Contrast effects in judgmental forecasting when assessing the implications of worst and best case scenarios

Two experiments investigated whether individuals' forecasts of the demand for products and a stock market index assuming a best or worst case scenario depend on whether they have seen a single scenario in isolation or whether they have also seen a second scenario presenting an opposing view of the future. Normatively, scenarios should be regarded as belonging to different plausible future worlds so that the judged implications of one scenario should not be affected when other scenarios are available. However, the results provided evidence of contrast effects in that the presentation of a second “opposite” scenario led to more extreme forecasts consistent with the polarity of the original scenario. In addition, people were more confident about their forecasts based on a given scenario when two opposing scenarios were available. We examine the implications of our findings for the elicitation of point forecasts and judgmental prediction intervals and the biases that are often associated with them.

Rules? Role Model? Relationship? The Impact of Parents on Their Children’s Problematic Mobile Phone Involvement

Parents can influence their children’s problematic mobile phone involvement (PMPI) by engaging in parental mediation activities, such as restrictions or co-use, by being a role model, and by their general and domain-unspecific parenting style that facilitates more or less attachment security of the child. This study tested the associations between these different routes of influence—parental mediation of the mobile phone, parental PMPI, and secure child-parent attachment—with children’s PMPI. Data was acquired from a quota-sample survey with 500 children, between 8 and 14 years of age, and one of their parents. Results point to the importance of open and empathic parent-child-communication, as well as a positive relationship quality, and demonstrate the detrimental effects of parents’ own PMPI on children’s PMPI.     

Subjective Well-Being During the 2008 Economic Crisis: Identification of Mediating and Moderating Factors

We examine the effects of the 2008 economic crisis on the reported subjective well-being (SWB) of nationally representative samples in 36 mainly European countries between 2002 and 2013. We study how SWB fluctuates along the business cycle, and how it is mediated by individual and country-level socioeconomic factors. Our key finding is that the economic crisis had a negative and S-shaped effect on SWB, implying diminishing marginal sensitivity at higher income losses and gains. During the economic downturn, roughly half of individual-level and macro-level determinants exhibit notable changes in significance and/or magnitude of the effect on SWB. This is taken as an indication of psychological adaptation and shifting reference frames. Five factors display an augmented effect on happiness and life satisfaction during the crisis (below-average income, the Gini index, attitude towards income equality, religiosity, and conscientiousness), while two determinants exhibit attenuated impact on the SWB measures (relationship status and unemployment rate).
