Therefore, this study aimed to further demonstrate whether differences in perceptions of inequality of opportunity and outcome negatively affects students’ educational aspirations. Further, based on previous research demonstrating positive main effect of internal locus of control (Sagone & Caroli, 2014) and a moderating effect of internal locus of control (Jia et al., 2021) on educational outcomes, locus of control was added as a moderator to see if an internal locus of control offsets negative effects of inequality on educational aspirations. Our manipulation, videos explaining inequality of opportunity and outcome, failed to tease apart perceptions of inequality of opportunity and outcome and were consequently combined into one factor, inequality. We found no significant main effect of perception of inequality, but a significant positive main effect of locus of control on educational aspirations. An interaction effect between perceptions of inequality and locus of control on educational aspirations was found. However, unexpectedly, students perceiving inequality within the external locus of control group scored highest on educational aspirations. Implications, limitations, and avenues for further research are discussed.Show less

Research indicates that students tend to have poorer diets during exam periods, with stress and sleep quality potentially influencing this pattern. The decline in diet quality among university students during examinations is a significant social issue that needs to further understanding. The aim of this study was to assess the relationship between exam stress and perceived changes in food choice -healthy or unhealthy eating- during an exam period among university students aged 18 to 25 and to assess to what extent this relationship is mediated by sleep quality during an exam period. Utilizing a cross-sectional design, data was collected from 200 Dutch university students who completed three questionnaires, the Examination Stress Scale, a questionnaire about changes in food choice during an exam period and the Regensburg Insomnia Scale. A mediation analysis was conducted using linear regressions in SPSS. The results indicated no significant relationship between exam stress and changes in food choice (β = .042 , p = .558). There was a significant positive relationship between exam stress and poor sleep quality (β = .44, p < .001). No significant association was found between sleep quality and changes in food choice (β = -.02, p < .770). When controlling for sleep quality, exam stress was still not associated with changes in food choices (β = .05, p < .514). Thus, the present study concluded that there is no relationship between exam stress and perceived changes in food choice -healthy or unhealthy eating- among university students ages 18 to 25 and that this relationship is not mediated by sleep quality during exams. However, there was a significant relationship between exam stress and poor sleep quality. Prevention strategies for exam stress and poor sleep should include stress management and education about the importance of sufficient sleep.Show less

Remaining open to alternative explanations, through exploring discourse of Afro-Brazilian movement Black Coalition for Rights, this study concludes that two forms of consciousness theoretically assumed to be different are both built on similar premises that recognise the role of capitalist structures in processes of racialisation.Show less

Symptoms of stress are a commonality of these disorders. However, the role of this commonality in the co-occurrence remains unknown. This cross-sectional study investigated the co-occurrence of depression, anxiety, and stress in adolescence using the network psychometrics approach. We obtained our data from the Open-Source Psychometrics Project. The data consisted of the Depression Anxiety Stress Scale (DASS)-42 (N = 25,086, ages 13-24 years old). We estimated Gaussian Graphical Models (i.e., partial correlations between nodes) and analyzed the bridge nodes. Bridge nodes are nodes of the network that are most influential in connecting the different disorders. We expected the bridge nodes to be the overlapping symptoms found among depression, anxiety, and stress as indicated in the DSM-V. Moreover, to examine whether bridge nodes were consistent across adolescence, we divided our sample into three age groups: early adolescence (ages 13-15, N = 2,354), middle adolescence (ages 16-19, N = 9,476) and late adolescence (ages 20-24, N = 13,256). Our findings of the full sample adolescent network indicated that symptoms of restlessness (stress) and negative mood (depression) served as bridge nodes, which was in line with our hypothesis. Other bridge nodes, not in line with our hypothesis, were symptoms of subjective experience of anxiety (anxiety) and situational anxiety (anxiety). Bridge nodes exclusive to the late adolescent network were: Finding it hard to wind down (stress) and feeling terrified (anxiety). Moreover, relief after anxious situations (anxiety) was uniquely present in the early and late adolescent networks. This study expands the current theoretical knowledge by, for the first time to our knowledge, including stress symptoms in the network models and by comparing the different adolescent age groups using a broad age range (13 to 24 years). Future research should examine whether clinicians can successfully incorporate this knowledge into transdiagnostic treatment interventions, which could contribute to better overall mental health.Show less

Research indicates a significant association between selective mutism and social anxiety. Moreover, specific parental behaviours, particularly overprotection, are linked to the development of social anxiety in children. In families with children diagnosed with selective mutism, various parenting styles are observed. Aim: This study analyses the possible relation between parental behaviour and social anxiety in four- and five-year-old children, both with and without the risk of developing selective mutism. Method: The current comparative study employs a cross-sectional design (n = 31), comprising fifteen children in the risk group and sixteen children in the comparison group. Two questionnaires completed by parents were used: the Social Anxiety Scale for Children Revised (SASC-R) to measure social anxiety in their children and the Comprehensive Early Childhood Parenting Questionnaire (CECPAQ) to assess parental behaviour. Results: The main findings indicate that children in the risk group exhibit higher levels of social anxiety and that their parents demonstrate less positive parenting behaviour compared to the control group. No relationship was found between positive parenting behaviour and social anxiety, with group status not being a significant moderator. However, a significant positive correlation was found between the level of structure provided by parents in the risk group and their children's social anxiety. Implications: Longitudinal research and parent-child observations are necessary to further verify and understand these findings. This study suggests that refining and improving interventions for selective mutism may involve increasing the focus on parental behaviour characteristics and parent-child interaction.Show less

As a result, the children at those schools are more severely affected by the shortage and the shortage therefore acts as a catalyst for social inequality. Strategies to prevent teacher attrition and to promote teacher retention remain unclear. Therefore, in this thesis the motivating and demotivating factors for being a teacher in The Hague were examined. Through interviewing primary education teachers (n=5) and secondary education teachers (n=5) in The Hague, along with a literature study, was attempted to define those factors. The self-determination theory was used as a framework to describe the motivation of teachers. Results showed that fulfilling the basic psychological needs could motivate teachers in their work, while failure to satisfy the basic needs could demotivate teachers. Autonomy seemed crucial, including involvement in decision-making, feeling heard and professional development aligned with personal interests. Relatedness seemed to be fostered through positive student-teacher relationships and the sense of contributing to students' development. Competence seemed to be undermined by illegitimate tasks, yet a strong bond with students made teachers feel competent along with good results from students. The findings of this study can be used in educating school leaders in motivating their teachers. It is hoped that this thesis forms a starting point towards a better understanding of teachers' motivation.Show less

Differences in literary skills exist and increase at early ages. It is important to close the gap early so that every child gets an equal opportunity to develop their literary skills. This research evaluates the effectiveness of digital readingaloud programs aimed at developing early literary skills, such as broad and deep vocabulary which form the basis for later reading comprehension. The role of active attention is studied, as differences in active attention during the reading-aloud programs might cause differences in effectiveness of the program on developing reading skills. Different reading-aloud programs are used in pre-school classrooms (groups 1 and 2 in the Dutch education system) during several weeks. A total of 88 toddlers, of which 53 girls, have participated. Participants’ levels of broad and deep vocabulary are measured prior to following the programs and each time after following one of the programs. Active attention is measured using observations. Results indicated a strong effect for the development of broad vocabulary over the programs, where a program with instructions focused on semantics had the strongest effects. Students with higher degrees of active attention showed greater increases in broad vocabulary. Deep vocabulary develops to a lesser extent and additional instructions from the teacher did not show stronger effects. Toddlers with different degrees of active attention seemed to develop their deep vocabulary similarly. Active attention might play a smaller role in the development of broad and deep vocabulary than previously thought. Follow-up research should be aimed at the development of programs that are effective for every child, especially for those at risk of falling behind.Show less

It has been recognized recently that vascular risk factors (VRF), such as hypertension, diabetes, and hyperlipidemia, can also have detrimental effects on these cognitive domains. Less research has been conducted on the synergistic influence of MCI and VRF on cognition, with available studies providing mixed results. Moreover, only one study has been conducted on the topic regarding the Greek population, so more research is needed to account for possible differences in ethnicity-related variables. Therefore, we sought to investigate how MCI with comorbid VRF influence PEM and EF, compared to VRF alone and healthy ageing. A sample of 111 Greek older adults participated in the study, divided into three groups: patients with MCI and concomitant VRF, patients with VRF and healthy controls. To assess cognition, tests were used to measure PEM, interference control, flexibility and semantic and phonemic verbal fluency. Data were analysed using MANCOVA, controlling for the educational level of the participants. Results showed that there were no differences between the two pathological groups for any of the measures, but the healthy controls outperformed the MCI+VRF (adjusted mean difference of total score being 8.94, 95 % confidence interval (CI) [3.67, 14.20], p < .001) and the VRF group (adjusted mean difference of total score being 8.20, 95% CI [2.94, 13.46], p < .001) in the semantic fluency task. Indeed, literature has shown that both MCI and VRF affect the integrity of frontal networks, which mainly support EF function. Methodological differences, such as the older age of the sample and the simplicity of the PEM task, ethnic differences and limitations in the statistical analysis can possibly account for the discrepancies with previous studies. All in all, this study suggests that there are no differences in cognition between VRF and MCI+VRF patients, while emphasizing the need for and more research into the cognitive consequences of comorbid MCI and VRF both in the Greek population and internationally.Show less

Therefore, gaining insight into prosocial behavior is important, so we can assist adolescents. However, previous studies on prosocial did not consider that prosocial behavior takes effort, such as holding the door open for another individual. Additionally, they did not explore whether cognitive and physical effort, and different effort levels, lead to variations in prosocial behavior among adolescents. Therefore, this study examined whether there are differences in cognitive and physical effort-based prosocial behavior in adolescents aged 9-12 across three different effort levels - low, medium, and high. In addition, age was taken into account as covariate. Effort levels referred to how much effort one had to exert in order to complete a specific task. 41 participants completed two experimental effort-based prosocial tasks. The cognitive task involved reversed digit spans, and the physical task was based on the Effort-Expenditure for Rewards Task, where the participant was required to tap on a predetermined number of boxes. The research question was investigated using a two-way repeated measures ANCOVA. Furthermore, an exploratory analysis was done using a three-way repeated measures ANCOVA, to investigate if adding the recipient as a within-subject variable would impact the results of the repeated measure ANCOVA. The main analysis revealed no effect of effort level, effort type, or interaction between these two. Age was not influential in the analysis either. The absence of differences highlighted the potential generalizability of neural mechanisms, the possible role of empathy as a moderator, and considered cognitive and physical effort-based prosocial behavior as constructs that vary across situations. However, the not-significant outcome could also be explained by the not-significant main effect of the recipient, found in the exploratory analysis. This study represented a new area of research that explored the nuances of effort-related prosocial behavior in adolescents. From our findings, we speculated that both kinds of prosocial behavior are equally beneficial, and result in favorable developmental consequences. Future research should investigate whether the findings are generalizable for mid and late adolescents and other forms of prosocial behavior.Show less

Furthermore, intrinsic motivation (IM) seems to be related to enhanced WM performance and learning, especially in feedback-contexts. However, research on the effectiveness of DT of WM in this age group, as well as the influence of IM, is lacking. Therefore, the current thesis aimed to study the effectiveness of our DT of WM, as well as the influence of IM. The study had a pretest-training-posttest design with two groups. The experimental group received training, whereas control group did not. The sample included 100 typically developing primary school children between 8 and 9 years old (Mage = 8.46, SD = 0.50, 51% girls). Contrary to previous findings, our results showed a decrease from pretest to posttest in WM performance in the control group and a slight increase in performance in the experimental group. Moreover, the children’s IM did not significantly influence the WM improvements when tested dynamically. The findings suggest that the training element in our DT could have protected against the decrease in WM from pretest to posttest and that IM did not have a significant influence on these results. These findings contribute to the field of research by highlighting the importance of factors such as sustained attention and time-on-task effects in the prevention of this decline in WM performance during DT. Besides these factors, future research should look into the effects of age, cognitive load and engagement on the DT of WM and IM to gain a better understanding on how to improve its effectiveness, especially in 8- to 9-year-old children. Further exploration could aid educational professionals in implementing the dynamic approach and supporting children’s learning processes and cognitive development.Show less
