Objectives: Associative memory (AM) declines due to healthy aging as well as in various neurological conditions. Standard transcranial electrical stimulation (tES) protocols show inconclusive facilitatory effects on AM, often lacking function specificity and stimulation focality. We tested the effectiveness of high-density electrode montage delivering anodal theta oscillatory-modulated transcranial direct current stimulation (HD-Theta-otDCS) over the left posterior parietal cortex (PPC), aiming to target AM in a spatially focused and function-specific manner., Methods: In a sham-controlled cross-over experiment we explored the differential effects of HD-Theta-otDCS applied during either encoding or the retrieval phases of two AM tasks (Face-Word and Object-Location). The stimulation protocol consisted of an anode over the left PPC (P3) and four surrounding return electrodes (CP1, CP5, PO3, POz) with electrical current oscillating in theta rhythm (5 Hz, 1.5 ± 0.5 mA)., Results: HD-Theta-otDCS stimulation applied during both encoding and retrieval increased AM performance compared to sham control in the Face-Word task. We found no differences between the two active stimulation conditions., Conclusions: HD-Theta-otDCS showed to be a promising tool for enhancing AM, regardless of the stimulation timing. The results provide further support for our previous findings with bipolar otDCS and confirm that PPC stimulation can induce behaviorally relevant modulation in the memory-related cortico-subcortical networks., Significance: The presented approach is one step forward towards precision brain stimulation for memory neuromodulation. The novelty lies in the combination of increased focality and function-specific current waveform. Positive results set the ground for further research on HD-theta-otDCS effectiveness in clinical populations., (Copyright © 2024 International Federation of Clinical Neurophysiology.

A growing body of evidence suggests that questionable health behaviors- not following medical recommendations and resorting to non-evidence based treatments-are more frequent than previously thought, and that they seem to have strong psychological roots. We thus aimed to: 1) document the lifetime prevalence of intentional non-adherence to medical recommendations (iNAR) and use of traditional, complementary and alternative medicine (TCAM) in Serbia and 2) understand how they relate to 'distal' psychological factors-personality traits and thinking dispositions, and 'proximal' factors-a set of beliefs and cognitive biases under the term 'irrational mindset'. In this preregistered cross-sectional study on a nationally representative sample (N = 1003), we observed high lifetime prevalence of iNAR (91.3%) and TCAM (99.2%). Irrational beliefs, especially magical health beliefs and medical conspiracy theories, were the strongest predictors of TCAM. They also mediated the relation between Disintegration/lower cognitive reflectiveness and TCAM. High Disintegration, and low Conscientiousness predicted iNAR directly, whilst negative experiences with the healthcare system facilitated both types of questionable health practices. The established psychological profile of people prone to questionable health behaviors and the fact they can be tracked to negative experiences with the system can be used to tailor public health communications., Competing Interests: The authors have declared that no competing interests exist., (Copyright: © 2024 Knežević et al.

The widely used Rational-Experiential Inventory-40 (REI-40) assesses Rational and Experiential thinking styles. Recently, the authors have distinguished three aspects of the Experiential style: Intuition, Emotionality and Imagination and developed the Rational-Experiential Multimodal Inventory (REIm). In this study, we examined the internal consistency, structural/factorial, discriminant and known-groups validity of both REI-40 and REIm, in two samples of Serbian students. Participants in Study 1 (N = 819, mean age M = 19.81, 31% males) completed REI-40 and HEXACO Personality Inventory (HEXACO-PI-R), while participants in Study 2 (N = 304, mean age M = 19.47, 29% males) completed REIm, HEXACO-PI-R and Disintegration inventory DELTA. The internal consistency of both REI version subscales was acceptable to good. The results of CFA analyses indicated an acceptable fit for REI-40, while the structural validity of REIm was poor. Both REI-40 subscales (Rationality and Experientiality), as well as REIm Intuition demonstrated only a small content overlap with basic personality traits, while REIm Experientiality, Emotionality and Imagination correlated highly with Openness and Emotionality. We also observed some gender differences in the expected direction., Competing Interests: The authors have declared that no competing interests exist., (Copyright: © 2023 Purić, Jokić.

Introduction: We will launch a national survey in Serbia to document the prevalence of two types of questionable health behaviours: (1) intentional non-adherence to medical recommendations and (2) use of traditional, complementary and alternative medicine practices, as well as the relation between the two. We will also investigate their psychological roots, including (a) 'distal' predictors such as HEXACO personality traits (plus Disintegration) and thinking dispositions (rational/experiential thinking and cognitive reflexivity), and (b) 'proximal' predictors under the umbrella 'irrational mindset' (set of unfounded beliefs consisting of conspiratorial thinking, superstition, magical health beliefs as well as selected cognitive biases), which have more content-wise overlap with the health behaviours., Methods and Analysis: In this cross-sectional study, a research agency will collect data from a nationally representative sample (n=1043; age 18-75 years; estimated start/end-June/November 2021) recruited online (approximately, 70% of the sample, aged 18-54; 11 years) and face-to-face (approximately, 30% of the sample, aged 55-75 years). Participants will complete a battery of tests assessing questionable health behaviours, basic personality traits, thinking dispositions, irrational mindset, sociopolitical beliefs, sociodemographic and health-related variables. Prevalence rates will be calculated using descriptive statistics. To explore the relation between (psychological) predictors and questionable health behaviours, we will use hierarchical regression and partial mediation models (path analysis or full SEM models)., Ethics and Dissemination: Ethical Committees of the Faculty of Philosophy in Belgrade (#935/1), Faculty of Special Education and Rehabilitation (#139/1) and Faculty of Media and Communications (#228) approved the protocol. Only participants who provide informed consent will participate in the study. A research report based on the study results will be submitted to peer-reviewed journals and results will be made available to stakeholders through reports on the project website https://reasonforhealth.f.bg.ac.rs/en/ and disseminated via social media., Trial Registration Number: NCT05808660., Competing Interests: Competing interests: None declared., (© Author(s) (or their employer(s)) 2023.

Introduction: An academic environment with continuously more demanding tasks requires students to capitalize on their strengths to meet the challenges and engage in learning experiences. Engaged students are deeply involved in their work, are strongly connected with their studies, and are more successful in academic tasks. The present study aimed to test a model in that core self-evaluations (CSE) predicts academic engagement (AE) directly and indirectly by increasing personal resources (i.e., psychological capital; PsyCap) in the case of two different samples, Romanian and Serbian., Methods: Data were collected through three online questionnaires from 672 undergraduate students (Romania - 458; Serbia - 214)., Results: The findings confirmed that CSE was positively related to PsyCap, which was positively associated with AE, and PsyCap mediates the relationship between the two variables in both samples. A positive evaluation of one's characteristics (high CSE) mainly affects the cognitive and emotional mechanism of appraising the academic-related tasks one encounters (high PsyCap), ultimately shaping their motivation and engagement., Discussion: These results pointed out the importance of the CSE and PsyCap that support each other and increase students' AE, explaining the mediating mechanism of PsyCap. Also, they provide insight into the students' engagement from two different cultural and educational contexts, being helpful to universities in their effort to increase students' engagement., Competing Interests: The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest., (Copyright © 2023 Paloș, Samfira, Vîrgă and Purić.)

Research shows the disruptive effects of early maltreatment on the autonomic nervous system (ANS) functioning in adulthood. Psychotherapists not only tend to report higher rates of personal experience with early maltreatment, but also fewer mental problems and disturbances in adulthood, as compared to other professions. However, the role of the ANS in these processes has been understudied despite the relevance of the therapist's psychological state and related nonverbal communication for the therapeutic alliance. By comparing body psychotherapists to the general population, the present study aimed to explore the effects of practicing body psychotherapy (BPT) on the link between early maltreatment and autonomic reactivity in adulthood. An online study included 570 body psychotherapists from 35 countries (54% from the United States, M age = 52.92, 81% of females) and 592 participants from the U.S. general population ( M age = 51.89, 78% females). We first inspected the factorial structure of the Body Perception Questionnaire-Short Form (Cabrera et al., 2018) in the specific population of BPT practitioners, confirming the three-factor model with one body awareness and two autonomic reactivity factors. Compared to the general population, BPT practitioners reported higher levels of childhood maltreatment, but fewer autonomic symptoms in adulthood, better differentiation of body awareness and autonomic reactivity, and a weaker association between childhood maltreatment experiences and present-day autonomic symptoms. Results are discussed in the framework of polyvagal theory (Porges, 1995, 2011). (PsycInfo Database Record (c) 2023 APA, all rights reserved).

The study of moral judgements often centres on moral dilemmas in which options consistent with deontological perspectives (that is, emphasizing rules, individual rights and duties) are in conflict with options consistent with utilitarian judgements (that is, following the greater good based on consequences). Greene et al. (2009) showed that psychological and situational factors (for example, the intent of the agent or the presence of physical contact between the agent and the victim) can play an important role in moral dilemma judgements (for example, the trolley problem). Our knowledge is limited concerning both the universality of these effects outside the United States and the impact of culture on the situational and psychological factors affecting moral judgements. Thus, we empirically tested the universality of the effects of intent and personal force on moral dilemma judgements by replicating the experiments of Greene et al. in 45 countries from all inhabited continents. We found that personal force and its interaction with intention exert influence on moral judgements in the US and Western cultural clusters, replicating and expanding the original findings. Moreover, the personal force effect was present in all cultural clusters, suggesting it is culturally universal. The evidence for the cultural universality of the interaction effect was inconclusive in the Eastern and Southern cultural clusters (depending on exclusion criteria). We found no strong association between collectivism/individualism and moral dilemma judgements., (© 2022. The Author(s), under exclusive licence to Springer Nature Limited.)

Although previous meta-analytic evidence supports the existence of parochialism in cooperation among adults, the extent to which children and adolescents are more willing to incur a personal cost to benefit ingroups, compared to outgroups, is not yet clear. We provide the first meta-analysis on the existence and magnitude of parochialism in cooperation among pre-adults. Based on 20 experimental economics studies (k = 69, N = 5268, age = 3-19, 12 countries, published 2008-2019), a multilevel meta-analytic model revealed a small overall effect size indicating that children and adolescents were more cooperative towards ingroups (d = 0.22, 95% CI [0.07, 0.38]). A series of single-moderator analyses tested for the following conditions: participant age and sex; game type ([mini-]dictator game, prisoner's dilemma, public goods dilemma, trust game, ultimatum game); outcome interdependence; membership manipulation (between- vs. within-subjects); group type (natural vs. experimental); reward type (monetary vs. non-monetary); and country of the participant. Parochial cooperation did not vary with participants' age. Parochialism was larger in non-interdependent (dictator-type) compared to interdependent (bargaining and social dilemma) games. There were no moderating effects of group type, membership manipulation or reward type. To provide more data on how parochialism develops, primary studies should report age ranges more precisely and use more restricted age groups., (© 2021 International Union of Psychological Science.)

The study aimed to investigate the role of personality, thinking styles, and conspiracy mentality in health-related behaviors during the COVID-19 pandemic, i.e., recommended health behaviors according to COVID-19 guidelines and engagement in pseudoscientific practices related to COVID-19. Basic personality space was defined by the HEXACO model complemented by Disintegration, which represents psychotic-like experiences and behaviors reconceptualized as a personality trait. Mediation analyses conducted on a convenient sample from the general population recruited via social media and by snowballing (N = 417) showed that engagement in pseudoscientific behaviors was predicted by high Disintegration. However, this relationship was entirely mediated by high experiential and low rational thinking styles. Adherence to health practices recommended by COVID-19 guidelines was predicted by high Honesty traits, while low Disintegration had both direct and indirect effects through conspiracy mentality., Competing Interests: The authors state that there is no conflict of interest., (© 2021 Elsevier Ltd.

The Metacognitions Questionnaire (MCQ-30) is a brief multidimensional measure used for assessment of metacognitive beliefs in psychopathology. The aim of this study was to assess the psychometric properties of MCQ-30 in Serbian nonclinical (n = 246) and clinical (n = 171; anxiety and depressive disorders) samples. The reliability of the questionnaire and its subscales was satisfactory. An exploratory factor analysis yielded a five-factor solution in both groups, whereas a confirmatory factor analysis showed a somewhat weaker fit of the model. The MCQ-30 showed positive associations with measures of anxiety, pathological worry, depressive, and obsessive-compulsive symptoms in both samples, demonstrating adequate convergent validity. The instrument was sensitive to differences in metacognitive beliefs between nonclinical and clinical samples. MCQ-30 subscales showed incremental contributions in predicting pathological worry after controlling for the variance in obsessive-compulsive symptoms and vice versa. Our results suggest that the MCQ-30 is a reliable and valid instrument for assessing metacognitive beliefs in both nonclinical and clinical samples. Moreover, the findings support the use of the MCQ-30 in Serbian population and extend support for the metacognitive model., (© 2019 John Wiley & Sons, Ltd.)

Background : Previous studies have demonstrated that traumatic experiences from countries of origin (so-called pre-migratory factors), as well as stressors in countries of destination (so-called post-migratory factors), are related to the extent of mental health difficulties and psychological well-being of refugees. However, numerous risks that this population is exposed to during transit have so far been neglected. Objective : The aim of this research was to construct and validate a questionnaire for assessing stressful and traumatic experiences in transit as well as its short form, which would at the same time provide information on one's stressful experiences as well as existing risks that refugees are exposed to on their journey. Method : The study was realized in three phases - item construction, item revision and instrument validation. In the validation phase, a total of 226 refugees completed the Stressful Experiences in Transit Questionnaire (SET-Q), along with Harvard Trauma Questionnaire (HTQ) Parts I and IV, Hopkins Symptom Checklist-25 (HSCL-25) and Beck Depression Inventory - II (BDI-II). Results : Refugees were exposed to an average of 13 stressful events during transit. SET-Q total score was positively correlated with HTQ Part IV Post-Traumatic Stress Disorder (PTSD) and Self-Perception of Functioning scales (SPFS) while the number of stressful experiences with the local population was positively related to BDI-II depression symptoms. Moreover, SET-Q scores were significant predictors of PTSD and SPFS even after traumatic experiences in the country of origin, assessed by HTQ Part I, were taken into account. A short form of the questionnaire (SET-SF) has also been developed. Conclusions : SET-Q is a valid instrument for measuring the scope of stressful experiences refugees have been exposed to during transit, targeted for this population specifically. Furthermore, SET-SF has the potential to assess the same extent of stressful experiences with a significantly reduced number of items.

The usual distinction between rational and intuitive thinking styles is still a subject of scientific debate, as there is no consensus about their nature, mutual relations and relations to other personality constructs. Cognitive-experiential self-theory (CEST) proposes rational and experiential thinking styles as original personality constructs not fully explainable by five-factor personality models. Following CEST, we aimed to examine: 1. The uniqueness of rational and experiential dimensions by relating them to other personality constructs: trait emotional intelligence (TEI) and HEXACO; 2. Thinking style profiles defined through combined rational and experiential dimensions, and the possible role of TEI in understanding them. A total of 270 undergraduate students (82% females) completed the TEIQue-SF, REI-40, and HEXACO-PI-R. Our results showed that constructs from all three paradigms were low to moderately correlated to each other. TEI had incremental validity in explaining both rational and experiential dimensions, but large amounts of their variances remained unexplained by both TEI and HEXACO. We revealed four thinking style profiles defined through combined rational and experiential dimensions. TEI was the highest when both dimensions were high and the lowest when both were low, which could be related to processes of understanding and managing emotional functioning - proposed as an essential part of TEI, while within CEST they are seen as the way in which rationality influences experientiality. This finding might be of specific significance for understanding irrationality as not exclusively related to high intuition, but to low rationality as well., Competing Interests: The authors have declared that no competing interests exist.

There is a growing body of evidence that a higher level of cognitive inhibition is associated with lower experimental pain sensitivity. However, a systematic examination of the association between executive functions, which include not only inhibition but also updating and shifting, and experimental pain sensitivity is lacking. This study aimed to overcome this limitation by exploring the relationship between a range of executive functions and different measures of experimentally induced cold pain in healthy participants. In a group of 54 healthy participants (age 21-24 years), executive functions (EF) were investigated in a systematic manner following a well-established framework developed by Miyake and collaborators. The investigation included multiple tests of inhibition (Stroop, Stop-signal, and Left-right), updating (Keep-track, Letter-memory, and Spatial n-back), and set-shifting (Plus-minus, Number-letter, and Local-global). The cold pressor test was used to obtain measures of pain threshold (the first sensation of pain), sensitivity to pain (the moment when substantial pain was reported), and pain tolerance (the moment when pain became unbearable). Results showed no relationship between pain measures and measures of updating and shifting. All pain measures were related to Stroop interference inhibition score, but not to other two inhibition tasks. Further analyses confirmed the unique relationship between Stroop-type of inhibition and response to pain. We argue that there is a fundamental relationship between cognitive inhibition and pain experience, which relies on one's ability to suppress automatic processes.

Previous studies with bilingual children have shown that the nature of their second-language instruction has an effect on the development of their cognitive abilities. The aim of this study was to determine whether children who acquire a second language in two different immersion programs for a period of 1year show advantages in executive functions and to examine how the amount of daily exposure affects executive functions. A group of Serbian-speaking second-grade children exposed to the second language for about 5h each day (high exposure group, HEG) and a low-exposure group (LEG) exposed to the second language for about 1.5h each day were compared with an age-matched control group (CG) of monolingual peers on working memory, inhibition, and shifting. Significant group differences were found for working memory, with the HEG performing better than the CG and LEG even after controlling for individual differences in terms of age and intelligence. The three groups did not differ in terms of inhibition and overall shifting abilities, although the control group had a marginally significant advantage on one of the two shifting tasks. Our findings extend previous research by demonstrating that the amount of daily exposure is a significant factor affecting executive functions in early immersion programs for second-language acquisition. In addition, they show that early intensive second-language acquisition can be advantageous for performance on tasks that require a higher level of executive control., (Copyright © 2017 Elsevier Inc.

Although large international studies have found consistent patterns of sex differences in personality traits among adults (i.e., women scoring higher on most facets), less is known about cross-cultural sex differences in adolescent personality and the role of culture and age in shaping them. The present study examines the NEO Personality Inventory-3 (McCrae, Costa, & Martin, 2005) informant ratings of adolescents from 23 cultures (N = 4,850), and investigates culture and age as sources of variability in sex differences of adolescents' personality. The effect for Neuroticism (with females scoring higher than males) begins to take on its adult form around age 14. Girls score higher on Openness to Experience and Conscientiousness at all ages between 12 and 17 years. A more complex pattern emerges for Extraversion and Agreeableness, although by age 17, sex differences for these traits are highly similar to those observed in adulthood. Cross-sectional data suggest that (a) with advancing age, sex differences found in adolescents increasingly converge toward adult patterns with respect to both direction and magnitude; (b) girls display sex-typed personality traits at an earlier age than boys; and (c) the emergence of sex differences was similar across cultures. Practical implications of the present findings are discussed. (PsycINFO Database Record (c) 2015 APA, all rights reserved)., ((PsycINFO Database Record (c) 2015 APA, all rights reserved).)

Consensual stereotypes of some groups are relatively accurate, whereas others are not. Previous work suggesting that national character stereotypes are inaccurate has been criticized on several grounds. In this article we (a) provide arguments for the validity of assessed national mean trait levels as criteria for evaluating stereotype accuracy; and (b) report new data on national character in 26 cultures from descriptions ( N =3,323) of the typical male or female adolescent, adult, or old person in each. The average ratings were internally consistent and converged with independent stereotypes of the typical culture member, but were weakly related to objective assessments of personality. We argue that this conclusion is consistent with the broader literature on the inaccuracy of national character stereotypes.
