This study investigated university students’ perceptions and concerns regarding the technology applied to educational purposes. Ninety-six students from Dutch higher education institutions, primarily female (71%), aged 18 to 24 (78%), and studying in the field of Behaviour and Society (60%), participated in the study by completing an online survey to reveal if and how they used GenAI chatbots for their assignments. Results showed that 84% of the participants that knew the tool used them for their assignments, with a mean frequency of use around several times a week, while 8% declared using the chatbots at least once a day. Students generally agreed that GenAI chatbots are useful for university tasks, especially associating the tool with an increase in productivity. Students’ main concerns were the risk to honest and ethical behavior, doubt about the reliability of generated content and plagiarism. The level of concern with potential negative effects of GenAI chatbots was negatively correlated with frequency of use. Students’ attitudes and concerns highlight the need for institutional guidelines to help them use the technology fairly and critically. Guidance could enable the use of GenAI chatbots to enhance productivity in school tasks while preventing issues related to academic integrity and security.Show less

These strategies activate prior knowledge and link it to new learning material. There are different generative learning strategies with age-related increase in effectiveness for children. For elementary school students, predicting seems to be an effective generative learning strategy. Would predicting as a generative learning strategy be equally effective for all elementary school students? These findings can be important for educational improvement. The present study examined the role of surprise in learning from predictions. It is important to understand if and how children learn from surprise. Furthermore, the role of response time (i.e. the time participants need to formulate a prediction), age and executive functions (inhibition, working memory and cognitive flexibility) on the effectiveness of predicting for learning numerical trivia facts was examined. The study was conducted with 27 children (11-13 years) and 44 young adults (20-24 years). It was found that a large expectation-violating prediction leads to better performance. These findings suggest that predictions with a large prediction error benefits learning. In addition, two main effects were found for age and task time on making predictions, with higher age and more task time leading to better predictions during the study phase. For the test results only a main effect for age was found, with young adults performing better on the memory test compared to children. More task time during the study phase did not lead to better memory. These findings suggest that an average longer task time leads to better predictions and there is an important role for age in predictions and testing. No significant effect was found for the general level of executive functioning. Future research is needed to gain more insight in making predictions in the classroom.Show less

Surprisingly, this method does not consider the impact of children's personality traits, despite literature indicating that these traits play a central role in their perspectives and can therefore influence the course of the interrogation and their testimony. This correlational study investigated the extent to which the personality trait 'shyness' plays a role in the course of the child interrogation according to the scenariomodel and in the quality of the witness statement. The research target group are children under the age of 12 who are victims of online sexual abuse. Participants (N = 23) underwent an ethically responsible simulation of online sexual abuse and a simulation of a child interrogation according to the scenariomodel. The transcripts of the interrogations were coded to first examine the quality of the testimony based on three indicators: accuracy of the statement, completeness of the statement and the amount of forensic information. And second to investigate the course of the interrogation based on the resistance that children show. Shyness was measured with a questionnaire. The study anticipated that shy children exhibit more resistance and provide lower quality testimonials due to their susceptibility to suggestiveness and social discomfort during interrogations. However, the results showed no significant correlations between shyness and the quality indicators of the testimony, nor between shyness and resistance. A mediating effect of resistance on the quality of the testimony was therefore also excluded. This suggests that the scenariomodel may be resistant to the negative influences of this personality trait and can be used without concern for interrogating shy children who have been victims of online sexual abuse. However, due to important limitations of the study, firm conclusions cannot be drawn and follow-up research is necessary.Show less

In addition, it was examined whether the quality of the parent-child relationship would moderate the relation between the quality of the sibling relationship and aggressive behavior between siblings during conflict. These relations were examined with a sample of 26 families, of which two siblings aged 8-15 years old and one parent participated. The amount of aggressive behavior during conflicts between siblings, quality of the sibling relationship and the quality of the parent-child relationship were measured by questionnaires. The results of this study showed a negative relation between the sibling relationship quality and aggressive behavior during conflicts between siblings, a positive relation between the quality of the sibling relationship and the quality of the parent-child relationship and a negative relation between the quality of the parent-child relationship and aggressive behavior during conflicts between siblings. The quality of the parent-child relationship did not act as a moderator for the relationship between the quality of the sibling relationship and the degree of aggressive behavior in conflicts between siblings. These results indicate a possible indirect role of the parent-child relationship quality in the degree of aggressive behavior in conflicts between siblings.Show less

In order to provide the most effective assistance to children with ASD, understanding the cognitive foundation of this disorder is crucial. There are several theories on this subject, yet there is limited research delving deeper into the potential connections between these theories. This research focused on the Central Coherence Theory and the Executive Dysfunction Theory and investigated whether there is a relation between these factors in explaining ASD. For this purpose, the Rey-Osterrieth Complex Figure Task, Tower of Hanoi, Picture Span and Autism Spectrum Questionnaire were administered to 89 children aged between 8 and 11 from six different primary schools in the Netherlands. Correlation analyzes were conducted to examine whether performance on central coherence, planning, and working memory correlated with the level of ASD traits. Using the PROCESS Macro, a mediation analysis was conducted to investigate whether executive functions could mediate the relationship between central coherence and ASD characteristics. The results of this study indicated that neither central coherence nor planning nor working memory were associated with the number of ASD characteristics. Moreover, no mediating effect of planning or working memory could be found. The fact that the results were not in line with the expectations could possibly be related to the non-clinical sample used in the current study, among other things. Future research should continue to focus on further investigation into the relationship between central coherence and executive functions, carefully taking into account the heterogeneity of ASD.Show less

It is employed across various contexts and for diverse target populations. However, the extent of evidence supporting this method in literature is unclear. This thesis synthesizes multiple sources to provide a comprehensive overview of to which extend this topic has been researched: What is known about this methodology, its strengths and weaknesses, and the specific target groups under investigation? Through a narrative review, ten evidence-based and seven non-evidence-based sources have been integrated to present a holistic perspective on the field of competency-based intervention. Several sources have indicated that the application of this model is effective in improving behavior and psychosocial conditions, including youth residing in residential facilities, high-risk families, adolescents with severe psychiatric/behavioral issues, and elementary school children with antisocial behavior. Although indications have been found that this method brings many advantages in practice, it was concluded that there is not enough evidence for competence-based work in the literature due to limitations in the studies. There is a need for further research to assess the effectiveness of this widely used approach.Show less

A consequence is that many studies have been conducted into the effects of support on the well-being of people with an intellectual disability. But research into groups that have improved, deteriorated or remained the same in terms of quality of life in combination with support needs was lacking. Therefore, the purpose of this study is to investigate the characteristics of the forward, backward and equal groups and to discover whether the groups differ in support needs. This is relevant because it can improve care and support. Method: Over a period of 4 years, 234 participants with an intellectual disability between the ages of 17 and 71 took part. To measure the quality of life of people with an intellectual disability, the San Martin Scale was used, completed by a supervisor. The support needs were identified with the Contextual Interview, this was done with the help of family, psychologist and supervisors. Both measuring instruments were administered three times in 4 years. Results: the results show that the quality of life differs over time. The forward, backward and equal groups differ in the domains: housing, communication, attachment, self-determination and physical needs. This research suggests that housing, communication, attachment and (physical) needs influence the progression of quality of life. Conclusion: the findings show that there are differences between the forward, backward and equal groups on domains of support needs. This research suggests that good support per domain leads to improvement or stabilization of the quality of life of people with an intellectual disability.Show less

The subtype CD with callous-unemotional (CU) traits has been suggested to be part of the developmentary trajectory of psychopathy, with both being linked to amygdalar volume deficits. Research into the neurodevelopmental perspective of CD/CU+ has been inconsistent due to methodological, demographic and cultural factors. Therefore, the current study examined amygdala morphology in two matched juvenile groups: CD offenders (N = 51) and healthy control subjects (HC; N = 36). In an additional set of analyses, the CD group was divided in two subgroups: CD with CU traits (CD/CU+; N = 26), CD without CU traits (CD/CU-; N = 25), and compared to HC participants. Additionally, the influence of CU traits on brain morphology was assessed in a dimensional manner across all participants (N = 87). Analyses revealed significant lower left amygdalar volumes in all CD youth compared to HC youth, while no significant differences emerged in the right amygdalar volumes. Furthermore, no significant differences in amygdalar volumes emerged between CD/CU- vs. CD/CU+ vs. HC youths. Moreover, the severity of CU traits did not relate to brain morphology in a dimensional manner across all participants. The current findings reflect the complexity and inconsistency of research into the relationship between brain morphology and CD diagnosis, and add to the research into the neurodevelopmental perspective of CD/CU+Show less

Central coherence is an important skill that aids people in understanding situations they encounter in daily life but is also an important skill to support the process of learning. After all, new information has to be processed, organised and integrated, taking into account overall context and meaning. Research into autism spectrum disorders (ASD) in the past 4 decades has provided multiple findings that indicate that people with ASD have weak central coherence skills and therefore lack the ability to create meaningful or coherent wholes, but research findings have been mixed. In this study a process-oriented dynamic version of the Rey-Osterrieth Complex Figure (ROCF), in which the training part was built up according to the ‘graduated prompts’ method, was used to measure and train central coherence. Furthermore, the potential relationship between ASD characteristics of the children in this study and central coherence or improved central coherence following training was assessed. The participants in this study consisted of 49 pupils in grade 5 or 6 of regular Dutch primary school education (M = 8.96 years, SD = .76 years). The dynamic test, including training based on the ‘graduated prompts’ method, lead to significantly more progression in structuring the drawing of the complex figure compared to the unguided control group. Regarding a potential relationship between ASD characteristics and central coherence or improved central coherence, no relationship was found in this study.Show less

Given its negative effects on social, emotional and academic development, early intervention is deemed necessary. This study investigated the predictive role of emotion regulation and executive functioning, along with the mediating role of emotion regulation in the relationship between executive functioning and aggression problems. This current correlational study is part of the TRIXY project. The sample consisted of 47 children between the ages of three and seven year old. Aggression was measured using the Child Behaviour Checklist, emotion regulation was measured using the Child Behaviour Questionnaire – Very short form and the executive functions inhibition, planning ability, working memory and cognitive flexibility were measured using the Behavior Rating Inventory of Executive Functions (BRIEF) and the BRIEF-P. The findings indicated that children who experienced more difficulties in executive functioning exhibited heightened levels of aggressive behaviour. Additionally, research showed that emotion regulation is a mediating factor in the relation between executive functioning and aggression. However, the relation between these three constructs differ when splitting the sample in a group consisting of children aged three to four years of age and a group consisting of children who are five to seven years of age, indicating that the relation between these three constructs changes during development. Furthermore, research showed that inhibition, working memory, and cognitive flexibility were predictors of emotion regulation problems and aggression, with inhibition being the most significant predictor of aggression in all ages. Results showed no relation between planning ability, emotion regulation and aggression. This research contributes to the development of effective interventions and the understanding of the development of aggression.Show less

Parenting skills are crucial factors in a child's emotional, cognitive, social, and behavioral development. Data were collected from 20 parents of young children (3 - 5 years old). Parenting skills were assessed using self-report questionnaires regarding confidence in parenting, reflective capacity, and parental sensitivity. The child's temperament was also assessed through questionnaires filled out by the parents. All multiple regressions were non-significant, and the relationships between parental mental well-being and parenting skills were not moderated by the child's temperament. This means that parental mental well-being and the child's temperament were not sufficiently predictive of parental self-confidence, reflective capacity, and parental sensitivity in parenting. By examining the correlations, a moderate positive relationship was found between parental mental well-being and their confidence in parenting. Parents with higher mental well-being had more confidence in their parenting. Parental mental well-being was negatively associated with their reflective capacity, indicating that parents with lower mental well-being displayed higher levels of reflective capacity. A moderate positive relationship was found between the child's temperament and parental sensitivity, suggesting that parents of children with a more challenging temperament were generally more sensitive in their parenting.Show less

For the study, 26 sibling pairs aged 8-15 years were included. These were only biological siblings and all lived in or near Leiden. The sibling pairs came to Leiden University to individually complete a VR task and a computer task and to fill out a questionnaire (SRQ-S). The parent also completed a questionnaire (CBCL 6-18 years) during the study. For this study, the CBCL and the SRQ-S were used. For this specific study, the younger sibling was examined because the older sibling influences the younger sibling more than the younger sibling influences the older sibling. The study found that conflict in a sibling relationship was positively related to internalizing behavior problems in the younger sibling. This can be explained by the cognitive model of depression: conflict causes stress and this stress relates to negative distortions of reality. These negative distorions of reality can form negative cognitive schema’s which relate to internalizing problems. There were no associations between warmth and internalizing problems and between warmth, conflict and externalizing problems. These conclusions must take into account that a general population sample was used: there were no high or low rates of warmth, conflict, internalizing and externalizing problems; they were avarage.Show less

How successfully parents’ cope with the competing demands of being a working parent can have an influence on their well-being. It was proposed that a relationship between the policies parents use, and their general well-being would be also influenced by several factors, such as the age of the child, the gender of the parent, and the characteristics of the child. 137 working parents accessed an online survey through social media where they would report on demographics and the policies they have used and their level of satisfaction. Additionally, they completed the GHQ-12 for general well-being and Mary Rothbart’s temperament questionnaires, IBQ, ECBQ or CBQ, depending on their youngest’ child age. Linear regression analyses were performed to analyze the potential relationship between policies and well-being, as well as a hierarchical multiple regression analyses for moderation effects. Lastly, results did not support the hypotheses; however, a relationship between policies and general well-being was concluded. Against the initial hypothesis, it was found that parents that make use of a lot of policies are predicted to report lower general well-being levels, presenting a quality-quantity dilemma. This is explained through the parents’ subjective experience of policies. Companies are urged to provide adjusted support to their working parents while taking their opinion and individual circumstances into consideration.Show less

Specifically, it sought to determine whether variations in working memory and planning abilities influenced children's learning potential and whether gender moderated these relationships. It is relevant to conduct research on this topic because current studies are scarce or inconsistent. Additionally, it can provide valuable insights into how education can be further tailored to maximize the potential of students. Using a MANOVA, the research analyzed the interplay between cognitive factors and learning potential, measured via the Dynamic Rey-Osterrieth Complex Figure Task (drawing task for learning potential), Picture Span (working memory), and Tower of Hanoi (planning skills). Separate MANOVAs examined the impact of working memory and planning skills, individually and combined, on learning potential, and explored interaction effects with gender. This multivariate approach allowed for a comprehensive evaluation of these relationships. However, the study found no significant relationships between working memory, planning skills, and learning potential. Additionally, gender did not significantly moderate these associations. These findings underscore the need for caution in assuming the sole importance of working memory and planning skills in children's learning potential. They highlight the complexity of factors influencing learning outcomes, suggesting that other variables beyond cognitive abilities may play crucial roles. Moving forward, future research should adopt a broader perspective, considering a wider range of factors such as motivation, emotional intelligence, socioeconomic status, and environmental influences. Additionally, employing more reliable measurement tools and accounting for contextual and individual differences will be essential for a nuanced understanding of the intricate dynamics shaping children's learning potential.Show less
