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

However, it is uncertain if the ability to learn sequences of movements is also impaired in this population. Therefore, this study investigated whether aMCI and AD affect motor sequence learning abilities, and how such abilities are related to AD biomarkers. The sample included 33 individuals with aMCI, 28 with AD, and 52 healthy controls (HCs). All groups completed a motor task consisting of performing a sequence of button presses, alternated with random blocks. Reaction time, coefficient of variation, and learning rates were obtained from the task. Participants also completed a series of cognitive tests to assess memory, visuospatial abilities, processing speed, language, and attention. Additionally, the following biomarkers for AD were assessed: amyloid beta via PET imaging, hippocampal volume via structural MRI, and number of e4 alleles via APOE genotyping. ANOVAs showed that AD participants had longer and more variable reaction times, followed by aMCI individuals, and with HCs having the shorter and more consistent reaction times. No significant differences in sequence learning rate were observed between groups. Exploratory analyses revealed that aMCI/AD had significantly slower initial learning rate than HCs. Linear regressions showed associations of slower reaction times with smaller hippocampal volume, and of higher coefficients with higher amyloid deposition. Poisson regressions revealed no significant correlations between motor sequence learning and APOEe4 allele count. Akaike Information Criterion (AIC) results indicated that combining cognitive test with motor measures improves the prediction of AD biomarkers. Overall, AD and aMCI individuals showed impairments in general motor performance but relatively preserved motor sequence learning abilities, with some deficits in initial rate of learning. Moreover, statistical model comparison suggested that adding motor sequence learning measures to neuropsychological assessment tools enhanced the prediction of AD biomarkers. As such, future studies should explore the value of integrating motor sequence learning measures in the assessment and tracking of AD/aMCI.Show less

However, non-motor symptoms such as cognitive decline are prevelant in up to 80% of PD patients. Multi-system degeneration and neurotransmitter decifiences are likely the cause. One of the systems implicated in PD-related cognitive decline is the cholinergic system but it remains unclear to what extent the system is affected and how it links to different disease stages. This retrospective cohort study explores the integrity of the cholinergic system in PD through the measurement of alpha reactivity using electroencephalography (EEG). EEG data from 191 participants, including 46 early-stage PD patients, 17 late-stage PD patients, and 128 healthy controls was analyzed. Alpha reactivity, measured as the difference in alpha power between eyes closed and eyes open conditions, was assessed via EEG. Cognition was assessed via the Mini-Mental State Exam (MMSE). Results revealed significantly reduced alpha reactivity in PD patients compared to healthy controls. ANCOVA analyses demonstrated reductions in alpha reactivity in both early-stage and late-stage PD groups when compared to healthy controls. However, no significant reduction in alpha reactivity was found between early and late-stage PD patients. These findings provide neurophysiological evidence of a reduction in alpha reactivity in PD patients, which could indicate a cholinergic dysfunction in PD, irrespective of disease stage. This study also highlights the potential utility of alpha reactivity as a biomarker for assessing disease severity.Show less

Concurrently, the phenomenon of brain drain, characterized by the migration of skilled individuals to foreign shores, poses a considerable challenge to these nations. This study employs linear regression analysis to delve into the impact of educational assistance on emigration rates, with a particular focus on the dynamics of brain drain. Drawing from diverse theoretical frameworks, including Schumpeter's theory and insights gleaned from entrepreneurship studies, this research formulates hypotheses to elucidate the relationship between educational development and emigration. It undertakes a comprehensive examination of perspectives surrounding brain drain and delineates the role of education in nurturing sustainable development, with the overarching goal of unraveling the intricate interplay between education and emigration. This research contributes to the discourse on development by offering evidence-based insights into the complications of education assistance affecting brain drain. By understanding the nexus between education and emigration, policymakers can formulate targeted strategies to harness youth talent and drive economic progress in low-middle-income countries, without driving them abroad.Show less

This discrepancy may partly stem from the complex and multifaceted nature of migration, with the climate factors influencing economic opportunity and conflict, making it difficult to differentiate between people that migrate for climate reasons and people that migrate for other reasons, such as economic opportunities. However, it more likely arises from people being trapped within their increasingly uninhabitable homes, because they do not have the capacity to move or willingness to leave their home. Therefore, policymakers and researchers should redirect their attention to immobility, as the ‘trapped populations’ are an urgent and underexposed problem. This thesis will examine the term 'trapped populations,' by using conceptions of Zickgraf (2019, 2023) and De Shalit (2011) and clarifying the complexities inherent in their immobility. I will argue for ‘the right to stay’ as the most protective right for the interests of the trapped populations, as it respects the importance of a home in a person their life.Show less

Political parties in European countries have responded differently to this influx of people. This study aims to clarify the relationship between the agenda of these political parties and the European migration crisis. Based on qualitative research, a content analysis was used to study the differences between left-wing, right-wing and centre-parties and how the European migration crisis has impacted these points of view. The analysis shows that political parties with different ideologies about migration react differently to the crisis. The European migration crisis has little to no effect on the agenda of left-wing parties and right-wing parties, but a major effect on the agendas of centre-parties.Show less

The contribution of this paper is two-fold. First, it gave an extensive overview of relevant research from numerous fields, which were subsequently combined into one overarching theoretical framework. Secondly, a preliminary empirical analysis was conducted using multiple linear regression (OLS) models to test the resulting expectations - that horizontal inequalities (economic and political) are likely positively related to civilian victimisation during civil wars. The analysis came back with mixed results, and at best limited and indirect support for the expected positive link between horizontal inequality and civilian victimisation.Show less
