Participants were 127 adolescents aged between 10 and 14 years old who reported on their empathy, prosocial behavior, and self-perception of close friendships in three consecutive years, respectively. Simple mediation analyses revealed that cognitive and affective empathy did not have a significant positive effect on adolescents’ self-perception of close friendships two years later. Considering these findings, prosocial behavior was not found to be a mediator between adolescents’ cognitive or affective empathy and their self-perception of close friendships from late childhood to early adolescence. Moreover, cognitive and affective empathy did not significantly predict prosocial behavior one year later, whereas prosocial behavior did significantly predict the self-perception of adolescents’ close friendships one year later. These results underline the significance of developing tailored intervention programs targeting prosocial behavior to foster adolescents’ self-perception as close friends, a competence that is crucial during this developmental period considering the greater influence of peers.Show less

Op dat moment vindt er een terugval plaats, ook wel een setback genoemd. Na het ervaren van een setback wordt het moeilijker een gedragsdoel vol te houden. Deze studie onderzoekt waarom dit moeilijk wordt door de relatie tussen de ervaren setbacks tijdens het volgen van een dieet en maintenance self-efficacy te analyseren, met subjectief succes als mogelijke mediator. Met een online vragenlijst (N= 74) zijn de ervaren setbacks, maintenance self-efficacy en subjectief succes uitgevraagd. De vragenlijst had een cross-sectioneel, between-subjects design. De antwoorden op de vragenlijst zijn geanalyseerd met lineaire regressieanalyses en met een mediatie analyse. De resultaten lieten een significante negatieve relatie zien tussen de ervaren setbacks en maintenance self-efficacy. De relatie tussen de ervaren setbacks en subjectief succes was significant negatief, maar de relatie tussen subjectief succes en maintenance self-efficacy was niet significant. Echter, de resultaten lieten zien dat de ervaren setbacks weldegelijk negatief gerelateerd waren aan maintenance self-efficacy, en dat subjectief succes een negatieve mediërende rol in deze relatie kan hebben. Samengevat, de resultaten suggereren dat de ervaren setbacks kunnen zorgen voor een afname in maintenance self-efficacy en subjectief succes, wat weer zou kunnen leiden tot een toename in het ervaren van setbacks. Deze resultaten hebben gezorgd voor nieuwe inzichten, maar meer onderzoek is nodig naar andere mediërende factoren zoals recovery self-efficacy om het setback effect beter te kunnen begrijpen.Show less

To address this effectively, it’s important to understand to what extend factors such as academic stress, parental expectations and family well-being influence the development of anxiety and mood disorders. Relatively little is known about the anxiety and worry experienced by early adolescent children and the extent to which this is culture dependent. The present study sought insight in the worries of children aged 10-12 years from Western and non-Western cultural backgrounds. In addition, the extent to which internalizing symptoms are related to achievement anxiety, parental expectations and family well-being was examined. This was done by interviewing 74 Indian children (M = 10.92 ; SD = 0.75) and 69 Dutch (M = 11.17 ; SD = 0.92) children using the Cultural Formulation Interview. In addition, the amount of internalizing complaints and family welfare were determined using RCADS and FASIII. Results showed that children from India more often experienced achievement-oriented anxiety than Dutch children, and that this was associated with a greater amount of internalizing symptoms. The parental expectations that Indian children experienced were often achievement-oriented expectations regarding school or future profession, whereas the parental expectations of Dutch children were more often focused on being able to show responsibility for tasks. This might be explained by the values transmitted from parent to child within individualistic and collectivistic culture. Evidence exists that cultural values remain present when families from collectivist cultures move to a country with a more individualistic culture. It is therefore extremely important to be aware of these cross-cultural differences within mental health care, as well as education, when dealing with adolescents with anxiety and mood problems.Show less

It is hypothesized that exercise of moderate and high intensity enhance creativity more effectively than exercise of lower intensity. The study also investigates if arousal, positive high-arousal affect, and negative high-arousal affect serve as intermediary variables in this relationship. Scarce previous research has suggested a relationship between exercise-intensity and creativity, but studies comparing different exercise-intensities on creativity and potential underlying mechanisms were lacking. To address this knowledge gap, this study compares different intensities, namely low-intensity (cycling at 55% of maximum heart rate), moderate-intensity (cycling at 70% of maximum heart rate), high-intensity (cycling at 85% of maximum heart rate) and a control group, on divergent creativity (i.e., number and uniqueness of creative ideas); And looks at affect and arousal as underlying mechanisms. Happy (positive), elated (positive), upset (negative), tense (negative) and stressed (negative) are used as indicators for high-arousal affect and feelings of wakefulness and alertness as indicators for arousal. Participants in this study completed two appointments, of which the first appointment consisted of a fitness test to measure participants’ maximum heart rate. During the second appointment, participants were randomly assigned to one of the four conditions and their affect and arousal were measured before and after the exercise or control task. Creativity was measured after the exercise or control task was completed. A Kruskal-Wallis Test showed that participants in the moderate-intensity and high-intensity exercise did not show higher creativity. Further, macro PROCESS model 4 revealed a significant effect of moderate-intensity and high-intensity exercise on arousal in comparison to low-intensity exercise and a significant effect of moderate-intensity exercise on positive high-arousal affect, in comparison to the control group. Other than this, the model revealed that none of the mediators significantly explained a relationship between exercise-intensity and creativity. This study thus suggests that exercise-intensity does not play a significant role in creativity enhancement, nor does arousal or high-arousal affect. However, future research is needed to confirm this for other modes of exercise, regular exercise instead of acute bouts of exercise and for different individual characteristics, such as age and gender.Show less

While TMS appears promising for stroke rehabilitation, there is variability in the level of improvement individuals exhibit. This variability may be attributed to oscillatory neurophysiology, which refers to the rhythmic electrical activity of the brain. Therefore, this study investigated phase-dependent changes in cortical excitability after TMS among stroke patients in affected and unaffected hemispheres. We investigated motor-evoked and TMS-evoked potentials at four phases of the ongoing motor cortical mu rhythm (trough, peak, rising, falling) in both hemispheres (affected, unaffected). Participants comprised N=11 chronic subcortical stroke patients (6 female, mean ± std age: 58 y ± 11.4) with affected lateralized upper-limb impairment. Four blocks of 150 TMS pulses were applied on each hemisphere, targeting the primary motor hotspot of the first dorsal interosseus muscle of the contralateral hand. Participants watched nature videos during stimulation to maintain consistent attention levels. Cortical excitability was assessed by analyzing motor-evoked potentials (MEP) and TMS-evoked potentials (TEP). Results showed that motor responses (measured through MEP amplitudes) were significantly larger at the trough and rising phase compared to the peak phase. No significant differences were observed between the affected and unaffected hemispheres. TEP components, the brain signals in response to TMS, did not exhibit significant phase-dependent changes. While our findings showed a nonsignificant effect of stroke severity, exploratory correlation analyses presented a positive association between higher remaining movement function and enhanced phase-dependent responses to TMS. The findings build upon previous research indicating phase-dependent changes in cortical excitability for MEPs but not for TEPs. The larger MEP amplitudes during trough and rising phases suggest that TMS can be more effective at specific points of cortical activity. Further exploration is needed to assess the efficacy of phase-specific TMS interventions in clinical settings, potentially through larger-scale clinical trials with longitudinal designs and comparative effectiveness studies, aiming to evaluate functional outcomes and determine their impact on motor recovery.Show less

Het huidige onderzoek bekijkt het effect van seksuele oriëntatie, gender en geslacht op de prestatie op een navigatietaak. Het onderzoek verspreidde een online vragenlijst met navigatietaak onder 216 deelnemers met een gemiddelde leeftijd van 27 jaar oud. 65 van de deelnemers waren van het mannelijke geslacht en 151 van het vrouwelijke geslacht. Hiervan waren 151 deelnemers heteroseksueel en 65 niet-heteroseksueel. Uit de resultaten van het onderzoek bleek dat seksuele oriëntatie, gender en geslacht geen effect hebben op de prestatie van mensen op een navigatietaak. Dit kan komen door de kleine individuele groepen binnen de niet-heteroseksuelen, waardoor er geen goede conclusie over de aparte groepen getrokken kan worden. Toekomstige onderzoeken zouden meer LHBTQIA+ organisaties kunnen betrekken bij het werven van deelnemers.Show less

Digital storybooks can lead to a child being read to more often since they don’t rely on an available adult to read aloud. This study investigated whether the teacher’s attitudes toward printed and digital storybooks correlated with their class's frequency of logging into Bereslim, an interactive digital storybook platform for children aged 3 to 7 years old. The study also examined whether the number of children in a class at risk of developing language problems correlates with the frequency of logins to Bereslim. Additionally, it investigated whether teacher’s attitude toward printed storybooks could predict the amount of Bereslim logins. Lastly, the study explored whether the teacher's age impacted their attitude toward reading digital storybooks and the frequency of logins. In this research 8 teachers from 6 schools and 1 daycare participated, completing an online questionnaire about their attitudes toward reading aloud with print and digital storybooks. Log data was also utilized, containing information about the frequency of logins into Bereslim in each class. No significant results were found regarding teachers' attitudes toward print and digital storybooks and the frequency of logging into Bereslim in their class. There was no significant correlation between the number of children in the class who are at-risk of developing a language problem and the teachers' attitude toward print storybooks. Neither teachers' age nor their attitudes toward digital storybooks significantly predicted login frequency. It's possible that the sample was too small to produce significant effects. To increase the usage of Bereslim in class, providing teachers with more information about the platform and opportunities to gain experience with digital storybooks could be beneficial. A lack of experience with digital storybooks prevents teachers from using them.Show less

The study investigated: (1) if there is an AB to or from itch; (2) whether this differs between people with chronic itch and healthy controls; (3) and if there is a possible AB/stress association. This is because understanding ABs to/from itch further elucidates the experience of patients with chronic itch and possible future clinical applications. Furthermore, an explorative analysis compared two tasks measuring AB, namely the Posner cueing and dot-probe task. The two tasks, alongside a stress-questionnaire, were administered online to the participants (N=70). A (frequentist and Bayesian) RM ANOVA was done for the main analysis, and a within- subjects t-test for the explorative task-comparison. Given that the task-comparison found the two tasks differing significantly (p = 0.01 d = -0.31), the results of the two tasks were interpreted separately. Overall, indications of AB being biased away from itch stimuli was found. When the AB was contrasted between participant group (people with and without chronic itch), the Posner cueing task found no significant difference (p = 0.68, ηp 2 = 0.003) whereas the dot-probe task found an AB away from itch-stimuli in patients with chronic itch (p = 0.02, ηp 2 = 0.077). Similar pattern unfolded with the stress-association: the Posner cueing task finding that AB did not significantly differ with stress (p = 0.23, ηp 2 = 0.021). The dot-probe task did find that they significantly differed (p = 0.01, ηp 2 = 0.091) where with higher stress, the AB switched to being an AB towards itch stimuli. The discrepancy between the two tasks aligns with expectations considering that the tasks were found inequivalent - highlighting one of the strengths of this study being that the two tasks were compared. Altogether this points towards differences in what the two tasks tap into, and that the attention of people with chronic itch is biased as a function of stress. Summarizing, AB to itch differed between the two groups and was associated with stress when using dot-probe task, which did not apply to the Posner cueing task.Show less

Data were collected using a scenario approach (N = 205) in an experimental study, which simulated a debt assistance setting in a municipality. The variables Status (low/high) and Warmth (low/high) were investigated in a betweensubjects design. Participants completed an online survey on perceived warmth, status, and locus of attribution of a help-seeker and indicated their willingness to help as well as the type of help. It was hypothesized that warmth perceptions of help-seekers would influence the likeliness to help, that status perceptions would influence the locus of attributions as well as the type of help and that the effect between status and type of help would be mediated by the locus of attributions. The study did not find support for these hypotheses. However, exploratory analyses revealed a significant positive effect of both Status and Warmth on perceived competence, and significant correlations between locus of attributions and likeliness to help, autonomy and dependency-oriented help, and emotions (admiration/envy/pity) and type of help. These findings underline the role of stereotypes and biases in influencing helping behavior, emphasizing the need for further investigations of helping mechanisms.Show less

This allows us to neglect several strong assumptions that are currently necessary to renormalize directed networks such as financial transaction networks. As an application, a model of ING’s transaction data has been derived across multiple coarse-grained partitions. In this article we provide detailed information on how this particular model has been structured and how its parameters are obtained. We show how we can use this model to determine the expected cumulative degree and weight distributions of ING’s transaction network across multiple coarse-grained partitions of the network which we will compare to the empirical degree and weight distributions, respectively.Show less

Investigating the multifaceted factors that attract visitors, including the roles of government initiatives and corporate efforts, the research explores the significance of K-pop within the broader context of influences on foreign K-pop fans’ decisions to visit South Korea. Through survey data collected from 1751 K-pop fans, the results demonstrate that K-pop has a substantial impact on their perception of South Korea, contributing positively to the country's image as a tourist destination. Furthermore, the research underscores the continued value of government and corporate efforts to attract visitors, particularly through the creation of K-pop-related locations for fan visits. While K-pop does not emerge as the primary motivational factor for half of the respondents, it emerges as the most influential factor shaping the intention to visit South Korea.Show less
