The dynamics between self-regulation problems and ADHD, MDD, and GAD may reveal insights into the co-occurrence of the three disorders. The present study focused on psychological factors that support or threaten successful self-regulation. Using cross-sectional data, a network analysis was performed based on a sample of 902 students currently enrolled in higher education programs in the Netherlands. The analysis featured 17 commonly studied risk and protective factors associated with all three disorders. The network showed that irritability and impairments in daily functioning were shared problems between ADHD, MDD, and GAD. The network further suggested that impaired cognition and a propensity for procrastination are shared features of ADHD and MDD. ADHD and GAD did not share a direct relationship, diverging from previous assumptions. The findings highlight that the relationship between the disorders may depend on shared vulnerabilities and outcomes that act as bridges in the network. The study illustrates that psychological constructs need to be more clearly defined to move forward when researching co-morbidity beyond the level of symptoms.Show less

According to the ego depletion theory, financial worry takes a toll on one’s cognitive performance and reduces one’s likeliness to initiate career-building. Meanwhile, better-regulated individuals tend to exhibit more proactive career behaviours as they are thought to be better in maintaining long-term goals and focus. Pearson’s correlation and regression analyses revealed a significantly positive correlation between financial stress and proactive career behaviours instead. However, financial stress non-significantly predicted of the variance of proactive career behaviours in students. Furthermore, we found that self-regulation was indeed positively but non-significantly correlated to proactive career behaviours, and that the former was a non-significant predictor of the latter as well. In addition, a surprising negative association was found between self-regulation and financial stress. The growing necessity for university students to exhibit proactive career behaviours remains a topic of relevance in today’s modern working climate, thus having implications on policy implementations for low-income university students. The present study hence adds nuance to the growing body of research regarding university students’ motives behind acting proactively when managing their careers, in that proactive career behaviours may arise from a dynamic combination of different contextual and individual factors.Show less

When a child attends school, a high level of self-regulation is necessary. Self-regulation is affected by many different factors, such as school context. Some of these factors are different in twins compared to singletons, since twins are more often compared to each other. It is still unclear how being in the same classroom or not effects the development of self-regulation in twins. Therefore, this study was designed to examine the effect of being in the same classroom on selfregulation in twins. There were 90 participants between the age of 3 and 4, followed for six years at three measurement timepoints. Self-regulation was measured by Dutch versions of caregiver questionnaires, the Children’s Behaviour Questionnaire and the Temperament in Middle Childhood Questionnaire. The long-term effect of being in the same classroom or not on the development of selfregulation and the effect of zygosity were also examined. The results showed a significant increase of self-regulation in twins from T1 to T2, but this was not affected by whether twins were in the same classroom or not. There was neither a significant long-term effect on being in the same classroom or not on self-regulation in twins nor an effect of zygosity. There seemed to be no difference in the development of self-regulation when twins were separated in school and when they were not, but for a broader understanding further research is recommended.Show less

Donald Trump’s withdrawal from the Paris Climate Accord, on June 1, 2017 and the recent refusal of Brazilian president Jair Bolsonaro to stop the exploitation of Amazon illustrate the emergence of a situation in which the notions of territory and nation-state no longer sustain the reality of our shared planet. The more climate change, global warming and the environmental degradation haunt the Earth’s inhabitants, the more it seems that we break apart the world as if boundaries of exclusion could prevent what is inside from perishing. In this thesis, I argue that, in the core of this issue, dwell precisely our ‘notions’ and ‘concepts’—enclosed in the huge monolith of Western modern thinking. To confront the planetary crisis, one needs a new strategy to access these problems—that would not consist in simply applying a dialectical method of discussion, but instead deploying a multidimensional approach, capable of penetrating that Western bloc from all sides. By taking on the notion of networks—whether informatic, political and biological—I critically analyse this concept and introduce the framework of the ‘swarm’ that I used in my own artistic practice as a way to allow a multiplicity of viewpoints. The art project Game of Swarms, which explores mainly the fact that the individuals of swarms work together without a locus of control, provokes the audience to rethink our current political structures and use the narrative of the game to imagine new forms of making politics and a new way to think our relation to the world. The biological self-organised model of swarms comes as a tool to create new narratives to face today’s planetary crisis and foster a more sustainable way of thinking.Show less

In dit onderzoek is aan de hand van het Still-Face Paradigma onderzocht of baby’s van 6 maanden oud over reactieve (‘positieve affectie’, ‘negatieve affectie’) en zelfregulerende vaardigheden (‘gaze’, ‘zelf-kalmerend gedrag’, ‘reiken/wurmen’) beschikken. Daarnaast is er onderzocht of baby’s van sensitieve moeders een betere zelfregulatie hebben dan baby’s van matig sensitieve moeders. Ook is de invloed van emotieregulatie van de moeder op de zelfregulatie van de baby onderzocht. 151 moeders die hun eerste baby verwachtten deden mee aan het onderzoek. Tijdens de zwangerschap is de DERS afgenomen. De drie opeenvolgende fasen van het SFP zijn opgenomen op camera waarna reactiviteit/zelfregulatie van de baby en sensitiviteit van de moeder door getrainde codeurs gecodeerd is. Uit de resultaten bleken baby’ s van 6 maanden tussen de verschillende episodes van het SFP significante verschillen te vertonen voor bijna alle componenten van reactiviteit/zelfregulatie. Alleen ‘zelf-kalmerend gedrag’ bleek niet significant. Het ‘still-face effect’, recovery effect’ en ‘carry-over effect’ waren aanwezig. Baby’s van sensitieve moeders tonen significant minder ‘positieve affectie’ en ‘gaze’ in de still-face’ episode. Emotieregulatie van de moeder bleek geen significante invloed te hebben op de reactiviteit/zelfregulatie van de baby. Het huidige onderzoek geeft aan dat baby’s van 6 maanden al zelfregulerende vaardigheden hebben. Er zal echter meer onderzoek moeten komen naar welke factoren van invloed zijn, en of de zelfregulatie effectief is.Show less

The goal of this research was to gain more understanding of the factors that influence stress reactivity. Method: The sample of the research consisted of 175 mothers and their offspring. The children were examined at the age of 12 months. The Lab TAB Robot task was used to measure the temperamental reactivity and self-regulation of the child and the Still Face Paradigm (SFP) measured sensitivity of the mother. Physiological stress reactivity of the child was measured using VU-AMS. Results: This research showed a significant difference between temperamental reactivity and sensitivity of the mother. There were no further significant differences. Discussion: Children of mothers who were more sensitive, had a higher temperamental reactivity, than children of mothers who were less sensitive.Show less
