Early group bias in the Faroe Islands: Cultural variation in children's group-based reasoning

Recent developmental research demonstrates that group bias emerges early in childhood. However, little is known about the extent to which bias in minimal (i.e., arbitrarily assigned) groups varies with children's environment and experience, and whether such bias is universal across cultures. In this study, the development of group bias was investigated using a minimal groups paradigm with 46 four- to six-year-olds from the Faroe Islands. Children observed in-group and out-group members exhibiting varying degrees of prosocial behaviour (egalitarian or stingy sharing). Children did not prefer their in-group in the pretest, but a pro-in-group and anti-out-group sentiment emerged in both conditions in the posttest. Faroese children's response patterns differ from those of American children [Schug, M. G., Shusterman, A., Barth, H., & Patalano, A. L. (2013). Minimal-group membership influences children's responses to novel experience with group members. Developmental Science, 16(1), 47–55], suggesting that intergroup bias shows cultural variation even in a minimal groups context.     

Impacts of Flooding on the Quality of Life in Rural Regions of Southern Slovakia

Human activity has significantly influenced energy flows in the landscape. Physical and geographical features of an area in the context of natural processes highlight their influence on the human lives in the affected regions of Slovakia. The paper aimed on the influence of the extraordinary flooding impact in June 2013 on the quality of life in Slovak rural regions. We have investigated the impact of the resulting damage on human activities in the rural municipality of Ch?aba. The case study of southern Slovakia can provide a more realistic view at regularly flooded areas in Slovak geographical conditions. The target of our research was to map and monitor the situation during the floods and shortly after them and to draw proposals leading to a more operative approach in the context of comprehensive flood protection in Slovakia. The added value of the research is a creation of such graphical supporting documents, which could be served as a basis for creating the plan of flood prevention management in rural territories, as a part of negative impacts of floods reduction on human activities.     

Crossing grammar and biology for gender categorisations: investigating the gender congruency effect in generic nouns for animates

In formal gender languages, all nouns have grammatical gender, regardless of whether their referents have a biological sex. The question of whether the grammatical gender affects how the denoted entities are conceptualised is subject to ongoing debate. Here, we investigate the extent to which a gender congruency effect emerges for three categories of nouns, with a particular focus on generic nouns (or epicenes). In two experiments and two replications with native speakers of German, we used an implicit measure to test possible associations of nouns with biological sex. These experiments revealed a stable gender congruency effect for congruent animates, and a weaker effect for generic animates and non-animates. In a fifth experiment, we combined the implicit measure with an explicit measure and contrasted items that have strong versus weak associations with biological sex. The results indicate that the congruency effect is driven by item-specific associations rather than by grammatical gender.     

Assessing Dimensions of Pathological Narcissism: Psychometric Properties of the Short Form of the Five-Factor Narcissism Inventory in a Sample of Italian University Students

To evaluate the psychometric properties of the Italian translation of the Five-Factor Narcissism Inventory–Short Form (FFNI–SF), 1,063 Italian university students were administered the scale, along with the Pathological Narcissism Inventory (PNI) and the Measure of Disordered Personality Functioning (MDPF). In general, the FFNI–SF scales showed good internal consistency (median α = .76; median interitem r = .44) and structural analyses suggested a 3-component model of FFNI–SF scales that was similar to that reported by Sherman et al. (2015). FFNI–SF second-order scales yielded meaningful convergent and discriminant correlations with PNI second-order grandiose and vulnerable dimensions. Finally, FFNI–SF second-order scales correlated in expected ways with 2 dimensions of personality dysfunction.     

Strategy transitions during cognitive skill learning in younger and older adults: Effects of interitem confusability

Groups of young and old adults were trained for four sessions on a set of 24 alphabet-arithmetic problems. Problem sets were either highly confusable or highly distinct. Power-function and mixture-model fits to the means and standard deviations of the acquisition data, resolved at the participant problem level, were compared. "Shallow" power functions signaled that a problem was computed throughout training; "humped" mixture functions signaled a shift from slow computed solutions to fast retrieved solutions. Not surprisingly, shifts to retrieval occurred later for confusable problems, but there were also fewer shifts in that condition. Failures to shift, even after extended practice, suggest that retrieving problem solutions is an elective strategy, and not an automatic concomitant of skill training. Participants can be viewed as choosing between strategies that trade off benefits in speed against costs in accuracy. Older adults showed few retrieval solutions in either condition, perhaps because of their emphasis on accuracy.     

Task switching: on the origin of response congruency effects

When people frequently alternate between simple cognitive tasks, performance on stimuli which are assigned the same response in both tasks is typically faster and more accurate than on stimuli which require different responses for both tasks, thus indicating stimulus processing according to the stimulus-response (S-R) rules of the currently irrelevant task. It is currently under debate whether such response congruency effects are mediated by the activation of an abstract representation of the irrelevant task in working memory or by "direct" associations between specific stimuli and responses. We contrasted these views by manipulating concurrent memory load (Experiment 1) and the frequency of specific S-R associations (Experiment 2). While between-task response congruency effects were not affected by the amount of concurrent memory load, they were much stronger for stimuli that were processed frequently in the context of a competitor task. These findings are consistent with the idea that a large portion of the congruency effects stems from direct S-R associations and they do not support a sole mediation by task-set activation in working memory.     

Probabilistic retroactive interference: the role of accessibility bias in interference effects

Probabilistic retroactive interference (RI) refers to the interfering effects of intermixing presentations of an earlier studied response (A-B) with presentations of a competing response (A-D). As an example, for a 2/3 condition, a cue word was presented with its earlier studied response twice and its competing response once during the interference phase. Performance on direct and indirect tests of memory for earlier studied responses was combined to reveal dissociations between effects on recollection and accessibility bias. Manipulating probabilistic RI influenced accessibility bias but left recollection unchanged. Effects of probabilistic RI were compared with effects of traditional, nonprobabilistic RI. The authors contrast their dual-process model with traditional accounts of RI and discuss the importance of distinguishing between recollection and accessibility bias for understanding interference effects.
