On the Measurement of Implicative Dilemmas

The implicative dilemma (ID) is gradually receiving attention of clinical psychologists and researchers. Although research on its clinical relevance is promising, there are still some issues regarding its measurement that need further consideration. This article explores the adequacy of the different thresholds used to determine construct association, the efficacy of the different indices commonly used to measure IDs, and a verification of the ID not being a mere subproduct of the self-ideal distance. It also introduces a new index. Finally, guidelines are provided for practitioners on how to interpret the indices' numerical results in relation to major depression.     

The psychology of hate: Moral concerns differentiate hate from dislike

We investigated whether any differences in the psychological conceptualization of hate and dislike were simply a matter of degree of negativity (i.e., hate falls on the end of the continuum of dislike) or also morality (i.e., hate is imbued with distinct moral components that distinguish it from dislike). In three lab studies in Canada and the United States, participants reported disliked and hated attitude objects and rated each on dimensions including valence, attitude strength, morality, and emotional content. Quantitative and qualitative measures revealed that hated attitude objects were more negative than disliked attitude objects and associated with moral beliefs and emotions, even after adjusting for differences in negativity. In Study 4, we analysed the rhetoric on real hate sites and complaint forums and found that the language used on prominent hate websites contained more words related to morality, but not negativity, relative to complaint forums.     

Breaking Down the Bilingual Cost in Speech Production

Bilinguals have been shown to perform worse than monolinguals in a variety of verbal tasks. This study investigated this bilingual verbal cost in a large‐scale picture‐naming study conducted in Spanish. We explored how individual characteristics of the participants and the linguistic properties of the words being spoken influence this performance cost. In particular, we focused on the contributions of lexical frequency and phonological similarity across translations. The naming performance of Spanish‐Catalan bilinguals speaking in their dominant and non‐dominant language was compared to that of Spanish monolinguals. Single trial naming latencies were analyzed by means of linear mixed models accounting for individual effects at the participant and item level. While decreasing lexical frequency was shown to increase naming latencies in all groups, this variable by itself did not account for the bilingual cost. In turn, our results showed that the bilingual cost disappeared when naming words with high phonological similarity across translations. In short, our results show that frequency of use can play a role in the emergence of the bilingual cost, but that phonological similarity across translations should be regarded as one of the most important variables that determine the bilingual cost in speech production. Low phonological similarity across translations yields worse performance in bilinguals and promotes the bilingual cost in naming performance. The implications of our results for the effect of phonological similarity across translations within the bilingual speech production system are discussed.     

Development and Validation of a Brief Version of the Difficulties in Emotion Regulation Scale: The DERS-16

The Difficulties in Emotion Regulation Scale (DERS) is a widely-used, theoretically-driven, and psychometrically-sound self-report measure of emotion regulation difficulties. However, at 36-items, the DERS may be challenging to administer in some situations or settings (e.g., in the course of patient care or large-scale epidemiological studies). Consequently, there is a need for a briefer version of the DERS. The goal of the present studies was to develop and evaluate a 16-item version of the DERS – the DERS-16. The reliability and validity of the DERS-16 were examined in a clinical sample (N = 96) and two large community samples (Ns = 102 and 482). The validity of the DERS-16 was evaluated comparing the relative strength of the association of the two versions of the DERS with measures of emotion regulation and related constructs, psychopathology, and clinically-relevant behaviors theorized to stem from emotion regulation deficits. Results demonstrate that the DERS-16 has retained excellent internal consistency, good test-retest reliability, and good convergent and discriminant validity. Further, the DERS-16 showed minimal differences in its convergent and discriminant validity with relevant measures when compared to the original DERS. In conclusion, the DERS-16 offers a valid and brief method for the assessment of overall emotion regulation difficulties.     

On predicting others’ words: Electrophysiological evidence of prediction in speech production

The present study investigated whether lexical processes that occur when we name objects can also be observed when an interaction partner is naming objects. We compared the behavioral and electrophysiological responses of participants performing a conditional go/no-go picture naming task in two different conditions: individually and jointly with a confederate participant. To obtain an index of lexical processing, we manipulated lexical frequency, so that half of the pictures had corresponding names of high-frequency and the remaining half had names of low-frequency. Color cues determined whether participants should respond, whether their task-partner should respond, or whether nobody should respond. Behavioral and ERP results showed that participants engaged in lexical processing when it was their turn to respond. Crucially, ERP results on no-go trials revealed that participants also engaged in lexical processing when it was their partner’s turn to act. In addition, ERP results showed increased response inhibition selectively when it was the partner’s turn to act. These findings provide evidence for the claim that listeners generate predictions about speakers’ utterances by relying on their own action production system.     

Domestic horses (<Emphasis Type="Italic">Equus caballus</Emphasis>) prefer to approach humans displaying a submissive body posture rather than a dominant body posture

Signals of dominance and submissiveness are central to conspecific communication in many species. For domestic animals, sensitivities to these signals in humans may also be beneficial. We presented domestic horses with a free choice between two unfamiliar humans, one adopting a submissive and the other a dominant body posture, with vocal and facial cues absent. Horses had previously been given food rewards by both human demonstrators, adopting neutral postures, to encourage approach behaviour. Across four counterbalanced test trials, horses showed a significant preference for approaching the submissive posture in both the first trial and across subsequent trials, and no individual subject showed an overall preference for dominant postures. There was no significant difference in latency to approach the two postures. This study provides novel evidence that domestic horses may spontaneously discriminate between, and attribute communicative significance to, human body postures of dominance; and further, that familiarity with the signaller is not a requirement for this response. These findings raise interesting questions about the plasticity of social signal perception across the species barrier.     

Being both – A European and a national citizen? Comparing young people’s identification with Europe and their home country across eight European countries*

Abstract

It is a well-established fact that forming a mature and coherent political identity is one developmental task in adolescence and young adulthood. However, given different degrees of commitment on the regional, national, and European level, the question remains whether young people’s identification varies among those spheres? Drawing on data from the European Catch-EyoU-project, it was the goal of this study to examine whether young people can be classified according to their identification toward their home country and Europe and how these types are associated with age, gender, country as well as political interest, tolerance, and political participation. The study is based on adolescents and young adults from the Czech Republic, Germany, Great Britain, Greece, Estonia, Italy, Portugal, and Sweden (N = 9339; Mage = 19.62; 59.1% female). Cluster analysis revealed five types of young people’s identification with country and Europe which showed significant associations between group membership and tolerance, political interest, and participation. The implications of distinguishing types of identification and their associations with political outcomes are discussed.     

Ethical challenges in the COVID-19 research context: a toolkit for supporting analysis and resolution

ABSTRACTCOVID-19 is compromising all aspects of society, with devastating impacts on health, political, social, economic and educational spheres. A premium is being placed on scientific research as the source of possible solutions, with a situational imperative to carry out investigations at an accelerated rate. There is a major challenge not to neglect ethical standards, in a context where doing so may mean the difference between life and death. In this paper we offer a rubric for considering the ethical challenges in COVID-19 related research, in the form of an ethics toolkit for global research developed at the University of Edinburgh in collaboration with more than 200 global researchers from around the world. This toolkit provides a framework to support confrontation of ethical conflicts through the integrated and iterative analysis of Place, People, Principles and Precedents, throughout the research journey. Two case analyses are offered to exemplify the utility of the toolkit as a flexible and dynamic tool to promote ethical research in the context of COVID-19.
