A Short Measure of the Revised Reinforcement Sensitivity Theory – RSQ17

The need for a research and practical tool, such as a short, reliable, and valid personality assessment test, suggests researchers to create shortened versions of original instruments. Reinforcement sensitivity questionnaire (RSQ) was created in line with some basic premises of revised Reinforcement sensitivity theory, which proposes three motivational and emotional systems: Behavioral inhibition system (BIS), responsible for scanning environment for potential threats, Behavioral activation system (BAS), responsible for aproaching behavior, and the Fight/Flight/Freeze system (FFFS), responsible for behavior in the present threat. RSQ comprises five scales: BIS, BAS, Fight, Flight, and Freeze. The aim of this study was to develop a short version of RSQ, which would be beneficial to both research and practical purposes. Item response theory analyses were used for item selection. The study comprised two samples of participants, whereby Sample 1 (N = 837, 34.6% male, aged 18 – 82, M = 31.63, SD = 13.54) served as the derivation sample, while Sample 2 (818 participants, 43.6% male, 18?75 years, M = 29.65, SD = 12.52) served as validation sample. Factorial validity of the short RSQ was examined on both Sample 1 and Sample 2. Convergent and divergent validity of the short RSQ was examined using RST-PQ, Jackson-5, BIS/BAS scales, and Big Five Inventory. The results point to satisfactory internal consistency, factorial validity, and construct validity of the short RSQ, suggesting that it is an adequate measure for research settings or other contexts which require the use of short personality questionnaires.     

Extension Properties and Subdirect Representation in Abstract Algebraic Logic

This paper continues the investigation, started in Lávi?ka and Noguera (Stud Log 105(3): 521–551, 2017), of infinitary propositional logics from the perspective of their algebraic completeness and filter extension properties in abstract algebraic logic. If follows from the Lindenbaum Lemma used in standard proofs of algebraic completeness that, in every finitary logic, (completely) intersection-prime theories form a basis of the closure system of all theories. In this article we consider the open problem of whether these properties can be transferred to lattices of filters over arbitrary algebras of the logic. We show that in general the answer is negative, obtaining a richer hierarchy of pairwise different classes of infinitary logics that we separate with natural examples. As by-products we obtain a characterization of subdirect representation for arbitrary logics, develop a fruitful new notion of natural expansion, and contribute to the understanding of semilinear logics.     

Personality Traits and Metacognitions as Predictors of Positive Mental Health in College Students

Presence and absence of both psychological distress and well-being are important in predicting life outcomes among youths. Recently, scholars have been paying increased attention to the role of positive mental health (PMH) in predicting psycho-social well-being among young people. The present study aims to test a model designed to assess the unique contribution of personality traits and metacognitions to four domains of PMH (belief-in-self, belief-in-others, emotional competence, and engaged living) among young adults. A total of 795 Italian college students participated in the study. Path analysis revealed that different personality traits were contributors to different PMH domains, and that four of the five metacognitions domains (negative beliefs about thoughts, cognitive confidence, need to control thoughts, and cognitive self-consciousness) differently predicted the four PMH domains. In conclusion it would appear that a combination of personality traits and metacognitions are differently involved in PMH domains. These should be taken into account when developing preventive programmes to promote PMH among young adults.     

How do Lithuanian adolescents address identity questions? A four-wave longitudinal study on change and stability in identity styles

Abstract

The present investigation evaluated multiple patterns of change and stability in Berzonsky’s identity styles (informational, normative, and diffuse-avoidant) in a four-annual-wave longitudinal study with 468 adolescent boys and girls from Lithuania. A combination of mean level changes, high rank-order stability, and high profile stability has been found in this study. First, levels of informational and normative identity styles remained stable for girls, but decreased significantly for boys; levels of diffuse-avoidant identity styles remained stable for girls and boys. Second, the rank-order stability of the normative and diffuse-avoidant styles was lower for boys, than for girls. Third, the mean profile stability was high for girls and moderate for boys. In general, our findings highlighted substantial gender differences in multiple indices of change and stability of identity styles.     

Probability and conspiratorial thinking

Conspiracy theories as alternative explanations for events and states of affairs enjoy widespread popularity. We test one possible explanation for why people are prone to conspiratorial thinking: We hypothesize that conspiratorial thinking as an explanation for events increases as the probability of those events decreases. In order to test this hypothesis, we have conducted five experiments in which participants were exposed to different information about probabilities of fictional events. The results of all experiments support the hypothesis: The lower the probability of an event, the stronger participants embrace conspiratorial explanations. Conspiratorial thinking, we conclude, potentially represents a cognitive heuristic: A coping mechanism for uncertainty.     

How Accurate Are National Stereotypes? A Test of Different Methodological Approaches

We compared different methodological approaches in research on the accuracy of national stereotypes that use aggregated mean scores of real people's personality traits as criteria for stereotype accuracy. Our sample comprised 16,713 participants from the Central Europe and 1,090 participants from the Baltic Sea region. Participants rated national stereotypes of their own country using the National Character Survey (NCS) and their personality traits using either the Revised NEO Personality Inventory or the NCS. We examined the effects of different (i) methods for rating of real people (Revised NEO Personality Inventory vs. NCS) and national stereotypes (NCS); (ii) norms for converting raw scores into T‐scores (Russian vs. international norms); and (iii) correlation techniques (intraclass correlations vs. Pearson correlations vs. rank‐order correlations) on the resulting agreement between the ratings of national stereotypes and real people. We showed that the accuracy of national stereotypes depended on the employed methodology. The accuracy was the highest when ratings of real people and national stereotypes were made using the same method and when rank order correlations were used to estimate the agreement between national stereotypes and personality profiles of real people. We propose a new statistical procedure for determining national stereotype accuracy that overcomes limitations of past studies. We provide methodological recommendations applicable to a wider range of cross national stereotype accuracy studies. Copyright © 2018 European Association of Personality Psychology     

Differential influence of basic psychological needs on burnout and academic achievement in three southeast European countries

Several studies show the importance of basic psychological needs (BPN) for decreasing burnout and increasing grade point average (GPA), but, to our knowledge, no prior study has explored the potential contextual differences in Southeastern European countries. Moreover, even less is known about how this relationship may differ during stressful (exam) and less stressful (beginning of the semester) periods. Measures of the Maslach Burnout Inventory—Student Survey and BPN Satisfaction and Frustration Scale were translated and adapted. The study included a cross-sectional sample of students from Croatia, Serbia and Slovenia during beginning of the semester and exam period. Across all countries and both contexts, students with high autonomy need satisfaction showed the strongest decrease in burnout, followed by those with high competence need satisfaction. Students with high academic achievement showed an increase due to competence need satisfaction. Competence and autonomy need satisfaction were higher beginning of a semester, while burnout was higher during the exam period. BPN play an important role in educational settings—satisfaction of the need for autonomy and competence protects students from burnout, and the need for competence predicts greater academic achievement regardless of culture or time of the semester.     

Language comprehension vs. language production: age effects on fMRI activation

Normal language acquisition is a process that unfolds with amazing speed primarily in the first years of life. However, the refinement of linguistic proficiency is an ongoing process, extending well into childhood and adolescence. An increase in lateralization and a more focussed productive language network have been suggested to be the neural correlates of this process. However, the processes underlying the refinement of language comprehension are less clear. Using a language comprehension (Beep Stories) and a language production (Vowel Identification) task in fMRI, we studied language representation and lateralization in 36 children, adolescents, and young adults (age 6-24 years). For the language comprehension network, we found a more focal activation with age in the bilateral superior temporal gyri. No significant increase of lateralization with age could be observed, so the neural basis of language comprehension as assessed with the Beep Stories task seems to be established in a bilateral network by late childhood. For the productive network, however, we could confirm an increase with age both in focus and lateralization. Only in the language comprehension task did verbal IQ correlate with lateralization, with higher verbal IQ being associated with more right-hemispheric involvement. In some subjects (24%), language comprehension and language production were lateralized to opposite hemispheres.
