Importing Logics

The novel notion of importing logics is introduced, subsuming as special cases several kinds of asymmetric combination mechanisms, like temporalization [8, 9], modalization [7] and exogenous enrichment [13, 5, 12, 4, 1]. The graph-theoretic approach proposed in [15] is used, but formulas are identified with irreducible paths in the signature multi-graph instead of equivalence classes of such paths, facilitating proofs involving inductions on formulas. Importing is proved to be strongly conservative. Conservative results follow as corollaries for temporalization, modalization and exogenous enrichment.     

When different means bad or merely worse. How minimal and maximal goals affect ingroup projection and outgroup attitudes

Group members tend to perceive their ingroup relative to an outgroup as more prototypical for a common superordinate group because they project features of their ingroup onto the superordinate group. As a consequence, the ingroup is perceived as more positive than the outgroup (Mummendey & Wenzel, 1999). We extend the ingroup projection model by examining different types of ingroup goals: minimal and maximal goals as well as actual and ideal goals. Minimal goals should engender either‐or thinking and lead to more ingroup projection compared with maximal goals that should involve more nuanced thinking. Ingroup prototypicality in terms of ideal goals (e.g., what we ideally should strive for) was expected to show a stronger relation to outgroup attitudes than ingroup prototypicality in terms of actual goals (e.g., what we are actually striving for). We manipulated minimal and maximal goal orientation and assessed actual and ideal goals. Across two studies, relative ingroup prototypicality was higher in the minimal compared with the maximal goal condition. Moreover, ingroup prototypicality referring to ideal goals showed a stronger relation to outgroup evaluation than ingroup prototypicality referring to actual goals.

Acoustic communication in crocodilians: information encoding and species specificity of juvenile calls

In the Crocodylia order, all species are known for their ability to produce sounds in several communication contexts. Though recent experimental studies have brought evidence of the important biological role of young crocodilian calls, especially at hatching time, the juvenile vocal repertoire still needs to be clarified in order to describe thoroughly the crocodilian acoustic communication channel. The goal of this study is to investigate the acoustic features (structure and information coding) in the contact call of juveniles from three different species (Nile crocodile Crocodylus niloticus, Black caiman, Melanosuchus niger and Spectacled caiman, Caiman crocodilus). We have shown that even though substantial structural differences exist between the calls of different species, they do not seem relevant for crocodilians. Indeed, juveniles and adults from the species studied use a similar and non-species-specific way of encoding information, which relies on frequency modulation parameters. Interestingly, using conditioning experiments, we demonstrated that this tolerance in responses to signals of different acoustic structures was unlikely to be related to a lack of discriminatory abilities. This result reinforced the idea that crocodilians have developed adaptations to use sounds efficiently for communication needs.     

The relationship between acculturation preferences and prejudice: Longitudinal evidence from majority and minority groups in three European countries

A longitudinal field survey tested the reciprocal effects of acculturation preferences and prejudice among ethnic minorities and majorities. Data were collected at two points in time from 512 members of ethnic minorities and 1143 majority members in Germany, Belgium and England. Path analyses yielded not only the lagged effects of prejudice on acculturation preferences but also the reverse for both majority and minority members. The mutual longitudinal effects between prejudice and desire for culture maintenance were negative, and the mutual effects between prejudice and desire for culture adoption were positive for majority members. The reverse was the case for minority participants. Moreover, the two acculturation dimensions interacted in their effect on prejudice for majority participants but not for minority participants. The effect of desire for culture adoption on prejudice was moderated by perceived intergroup similarity. Theoretical and practical implications of the findings are discussed.

Some Theoretical Considerations on Attitude,Arousal and Affect during Cognitive Dissonance

This article provides a general overview of cognitive dissonance research with the induced compliance paradigm. We begin by describiang how dissonance affects individuals' attitude change and address issues related to measurement of attitude. Next, we describe the arousal component of dissonance, how it has been measured and the issues that have been raised about its nature. Finally, we explore the emotional component of dissonance and review different ways for measuring and identifying the negative affect associated to dissonance. We conclude by claiming that a more intensive study of the process of dissonance, and particularly of its arousal and emotional components, will allow a more in‐depth understanding of the mental processes involved in cognitive dissonance.     

When status differences are illegitimate,groups' needs diverge: Testing the needs‐based model of reconciliation in contexts of status inequality

The present paper extends the needs‐based model of reconciliation to contexts marked by status inequalities rather than by overt intergroup aggression. Specifically, we investigated whether and when members of high‐status versus low‐status groups experience divergent socio‐emotional needs vis‐à‐vis members of the respective other status group. Building on research informed by social identity theory, we hypothesized that the groups' different positions in the social hierarchy only translate into divergent needs when the status differences are perceived as illegitimate. In Study 1 (N = 130), we tested this prediction by manipulating status and perceived legitimacy of status differences in a setting with artificially created groups. Results confirmed that the need to be socially accepted by members of the other status group was stronger in high‐status compared with low‐status group members but, as expected, only when the status differences were perceived to be illegitimate. Also as predicted, the need to be empowered by the other status group was stronger in low‐status compared with high‐status group members, again only under conditions of illegitimate status differences. Study 2 (N = 169) further corroborated our perspective by replicating these findings in a naturalistic intergroup context. Implications for the role of legitimacy perceptions in determining differential socio‐emotional needs and for the promotion of sustainable social change are discussed.

Impact of Transplant-Related Stressors and Feelings of Indebtedness on Psychosocial Adjustment Following Kidney Transplantation

Forty-seven patients answered a questionnaire about stress, feelings of indebtedness toward the donor, and psychosocial adjustment following kidney transplantation. The combination of age, general life stress, and transplant-related stress explained 47% of the variance in psychosocial adjustment. Areas of adjustment most influenced by this combination of predictors included attitudes toward health care, domestic, vocational, social adjustment, and psychological distress. Younger patients endorsed higher levels of transplant-related stress and higher levels of psychological distress. Moderate to intense feelings of indebtedness toward the donor were common but were unrelated to psychosocial adjustment posttransplant.     

Blinded by the accent! The minor role of looks in ethnic categorization

The categories that social targets belong to are often activated automatically. Most studies investigating social categorization have used visual stimuli or verbal labels, whereas ethnolinguistic identity theory posits that language is an essential dimension of ethnic identity. Language should therefore be used for social categorization. In 2 experiments, using the "Who Said What?" paradigm, the authors investigated social categorization by using accents (auditory stimuli) and looks (visual stimuli) to indicate ethnicity, either separately or in combination. Given either looks or accents only, the authors demonstrated that ethnic categorization can be based on accents, and the authors found a similar degree of ethnic categorization by accents and looks. When ethnic cues of looks and accents were combined by creating cross categories, there was a clear predominance of accents as meaningful cues for categorization, as shown in the respective parameters of a multinomial model. The present findings are discussed with regard to the generalizability of findings using one channel of presentation (e.g., visual) and the asymmetry found with different presentation channels for the category ethnicity.     

Sequential or parallel processes? A longitudinal field study concerning determinants of identity-management strategies

Using a longitudinal field design, this study tested the dynamics of an integrative model of social identity theory (SIT) and relative deprivation theory (RDT) with regard to relations between perceived socio-structural characteristics, perceived in-group identification, perceived fraternal deprivation (i.e., resentment) and identity-management-strategy preference. Trait-state analyses revealed that the dynamic relationship among constructs in the model can best be explained in terms of trait-dependent variation rather than sequentially ordered processing. The trait components of the variables replicate previous findings concerning SIT and RDT. However. stable functional relations between variables and their traitlike character contradict the notion that their underlying processes are linear and sequential. Rather, variables and their relations can be regarded as the product of parallel processes. The authors discuss the results as a challenge to core assumptions of SIT.     

Negotiating Identity: Three Events that Weaken the Maternal Identity of Addicted Law-Breaking Women

This qualitative study aimed to comprehend how mothers experienced and built their maternal identity throughout their lives. Thirty-eight semi-structured interviews were conducted with drug-using and law-breaking mothers. Results showed that three events were significant for participants: pregnancies, loss of custody, and incarceration. As each event challenged their maternal identity, they questioned their substance use and their criminal involvement. Our results suggest that these events represent key moments to encourage their growing awareness and to foster changes in their deviant lifestyle. We conclude this article by discussing interventions possible for each of these important moments in these mothers’ lives.
