Externalities Awareness in Anticommons Dilemmas Decreases Defective Behavior

The present paper explores the effect of the salience of collective consequences of opportunistic behavior in commons and anticommons dilemmas. Making this type of externalities salient was expected to increase the awareness of the conflict between collective and personal interests, especially in the anticommons dilemma. The results of a vignette study (Study 1, N = 100) and a laboratory experiment (Study 2, N = 55) confirmed our hypotheses, revealing more opportunistic behavior in the anticommons than in the commons dilemma when externalities were not made salient, while no significant dilemma effect was obtained when the externalities were made salient. Moreover, the results of Study 2 demonstrated that the dilemma effect on cooperation was mediated by externalities awareness. The positive effects of increments in externalities awareness on cooperation are discussed. Copyright © 2011 John Wiley & Sons, Ltd.     

Philosophy as the In-Between

What is the difference between doing philosophy and doing the history of philosophy? Where should the line be drawn between “using” previous philosophers to make one's point and discussing what past philosophers claimed? In trying to confront these questions, this essay starts with a reflection on the difference between doing philosophy and doing the history of philosophy as proposed by the French philosopher Gilles Deleuze, and confronts it with a different one derived from the German philosopher Martin Heidegger. The ideas developed by Heidegger will then lead to a definition of “philosophy” and to some etymology-based reflections on what a “philosopher” is that Plato proposes in his “Symposium”. The essay continues by arguing that, when doing philosophy, it is necessary to return to philosophy's past in order to recoup philosophical momentum. The essay concludes with some reflection on the possible similarities between Plato's characterization of Eros as the first philosopher and the difference between doing philosophy and doing the history of philosophy.     

Expatriate Social Ties: Personality Antecedents and Consequences for Adjustment

This expaloratory study examines the relationship between personality characteristics (extraversion, core self evaluations), social tie characteristics (number, breadth, depth), and three types of expatriate adjustment (general, interaction, and work). Data was collected at two points in time from 75 expatriate employees from one organization on international assignments around the world. Results indicate that core self‐evaluations, but not extraversion, are positively related to the number of ties formed with other expatriates and host country nationals. Social ties with other expatriates were found to provide greater social support, but similar access to information, than those with host country nationals (HCNs). In general, depth and breadth of relationships with other expatriates predicted general and work adjustment; whereas, breadth and total number of relationships with HCNs predicted all three types of adjustment. Overall, these results provide initial support for the importance of social ties in facilitating expatriate adjustment.     

A qualitative analysis of the vaccine intention–behaviour relationship: parents’ descriptions of their intentions,decision-making behaviour and planning processes towards HPV vaccination

Objective: The objective of this study is to identify factors influencing the vaccine intention–behaviour relationship. Design: A total of 445 parents who received a brief intervention to promote HPV vaccination were categorized based on their intentions post-intervention (yes/unsure/eventually/never) and subsequent adolescents’ vaccine status (yes/no). Fifty-one of these parents participated in qualitative interviews. Main Outcome Measures: Parents described their intentions, decision-making and planning processes towards vaccination. Framework analysis was used to analyse the data. Results: Parents in the ‘Yes/Yes’ category were knowledgeable about HPV/vaccine, described strong, stable intentions, considered themselves the primary decision-makers about vaccination and said they vaccinated immediately. ‘Yes/No’ parents described strong intentions and thought their adolescent was vaccinated OR described hesitant intentions, seeking advice/agreement from others and noting barriers to vaccination without solutions. ‘Unsure/Yes’ parents described their intentions as strengthening with information from credible sources and identified strategies for overcoming barriers. ‘Unsure/No’ and ‘Eventually/No’ parents had misinformation/negative beliefs regarding vaccination, described being ambivalent or non-supportive of vaccination and cited barriers to vaccination. ‘Never/No’ parents held negative beliefs about vaccination, described strong, stable intentions to NOT vaccinate, deferring the decision to others, and reported no planning towards vaccination. Conclusions: Intention characteristics and planning processes could moderate the vaccine intention–behaviour relationship, potentially serving as targets for future vaccine strategies.     

The social‐psychological bases of far‐right support in Europe and the United States

The roles of authoritarianism, social dominance orientation (SDO), and prejudice in the prediction of far‐right support were examined in Europe and the United States. A meta‐analysis shows remarkably similar, positive, and strong associations of far‐right support with these three variables in previous studies conducted in Europe, the United Kingdom, and the United States. Results from two cross‐sectional studies in the United States further indicated that higher levels of authoritarianism and SDO related to higher voting intentions and support for Trump, via increased prejudice. In a three‐wave longitudinal study in the United Kingdom, authoritarianism and SDO predicted pro‐Brexit attitudes and support for the U.K. Independence Party, again via prejudice. These results shed a new light on the widely held beliefs in “American and British exceptionalism,” as Trump and Brexit adherents share the same social‐psychological underpinnings as far‐right supporters observed in several European countries.     

Clusterwise simultaneous component analysis for analyzing structural differences in multivariate multiblock data

Many studies yield multivariate multiblock data, that is, multiple data blocks that all involve the same set of variables (e.g., the scores of different groups of subjects on the same set of variables). The question then rises whether the same processes underlie the different data blocks. To explore the structure of such multivariate multiblock data, component analysis can be very useful. Specifically, 2 approaches are often applied: principal component analysis (PCA) on each data block separately and different variants of simultaneous component analysis (SCA) on all data blocks simultaneously. The PCA approach yields a different loading matrix for each data block and is thus not useful for discovering structural similarities. The SCA approach may fail to yield insight into structural differences, since the obtained loading matrix is identical for all data blocks. We introduce a new generic modeling strategy, called clusterwise SCA, that comprises the separate PCA approach and SCA as special cases. The key idea behind clusterwise SCA is that the data blocks form a few clusters, where data blocks that belong to the same cluster are modeled with SCA and thus have the same structure, and different clusters have different underlying structures. In this article, we use the SCA variant that imposes equal average cross-products constraints (ECP). An algorithm for fitting clusterwise SCA-ECP solutions is proposed and evaluated in a simulation study. Finally, the usefulness of clusterwise SCA is illustrated by empirical examples from eating disorder research and social psychology.     

Intensity profiles of emotional experience over time

A full understanding of emotions and emotion characteristics can only be reached when their dynamic nature is taken into account. As such, a primary objective of the present study is to describe and account for variability in temporal profiles of experienced emotional intensity. Participants were asked to make detailed drawings of intensity profiles of recently experienced episodes of anger, sadness, joy and affection. Functional data analysis revealed three features that together accounted for 84% of the total variability: (i) steepness at onset; (ii) skewness; and (iii) the number of peaks. Emotions differed with regard to the first two features, with the rise at onset being steeper for sadness and joy and affection being the most negatively skewed emotion under study. Individual differences regarding each of the three features were found, however, they did not strongly generalise across emotions.     

Opening closed minds: the combined effects of intergroup contact and need for closure on prejudice

Five studies tested whether need for closure (NFC) moderates the relation between intergroup contact and prejudice toward immigrants. The results consistently showed that intergroup contact was more strongly associated with reduced levels of prejudice among people high in NFC compared to people low in NFC. Studies 1 (N = 138 students) and 2 (N = 294 adults) demonstrated this moderator effect on subtle, modern, and blatant racism. Study 2 also replicated the moderator effect for extended contact. An experimental field study (Study 3; N = 60 students) provided evidence of the causal direction of the moderator effect. Finally, Studies 4 (N = 125 students) and 5 (N = 135 adults) identified intergroup anxiety as the mediator through which the moderator effect influences modern and blatant racism as well as hostile tendencies toward immigrants. The role of motivated cognition in the relation between intergroup contact and prejudice is discussed.     

The inhibition of verbally aggressive behaviour

We studied the inhibition of verbal aggression, defined as not displaying verbal aggression when one would want to. The approach we used was based on a situation–response questionnaire containing 15 anger provoking situations and three verbally aggressive responses. Two questions were asked for each combination of a situation and a response: one about wanting to react in a verbally aggressive way and one about actually displaying the reaction. This questionnaire was administered to 316 participants. Based on different theories about inhibition, several logistic mixed models were constructed and tested against each other. In the best fitting model, inhibition was conceptualized as a trait. Trait inhibition was negatively correlated with external measures of Anger Out and positively with Control of Anger Out.
