Current research has reported the beneficial effects of mindfulness-based interventions (MBIs) on general domains of cognition and behavior among children. The present study is the first meta-analysis with controlled studies investigating the pre-post change effects of MBIs on two widely experienced behaviors in childhood education, namely inattentiveness and hyperactivity–impulsivity. With a special developmental focus on the early years, a total of 21 studies with 3- to 12-year-old children were included in the meta-analysis. Results indicated that MBIs decreased children’s overall inattentive and hyperactive–impulsive behavior with a small but significant effect size ( k = 21, g + = .38, p < .001). However, this overall positive effect was only significant when teachers rated children’s behavior and nonsignificant when parents and children themselves were the informants. Additionally, MBIs showed a moderate effect in reducing inattentiveness and hyperactivity–impulsivity for children at risk for such behavior. In conclusion, results indicate that MBIs, which are relatively easily applied in educational practice, have the potential to decrease inattentive and hyperactive–impulsive behavior and might contribute to children’s overall better functioning at school.

This is the first pilot study with children that has assessed the effects of a brain–computer interface-assisted mindfulness program on neural mechanisms and associated cognitive performance. The participants were 31 children aged 9–10 years who were randomly assigned to either an eight-session mindfulness training with EEG-feedback or a passive control group. Mindfulness-related brain activity was measured during the training, while cognitive tests and resting-state brain activity were measured pre- and post-test. The within-group measurement of calm/focused brain states and mind-wandering revealed a significant linear change. Significant positive changes were detected in children’s inhibition, information processing, and resting-state brain activity (alpha, theta) compared to the control group. Elevated baseline alpha activity was associated with less reactivity in reaction time on a cognitive test. Our exploratory findings show some preliminary support for a potential executive function-enhancing effect of mindfulness supplemented with EEG-feedback, which may have some important implications for children’s self-regulated learning and academic achievement.

Although many studies have been carried out on the psychometric aspects of computerized adaptive testing (CAT), its psychological aspects are less researched. Early studies claimed that CAT can be more motivating and induce less anxiety than traditional fixed-item tests (FIT). The purpose of this systematic review and meta-analysis was to gain a comprehensive understanding of the effects of CAT on motivation and anxiety in comparison to traditional fixed-item testing. Seven databases were examined. Articles were eligible if they employed an empirical study containing a direct comparison between CAT and FIT. Meta-analytical results showed no overall effect of test type on anxiety and motivation when comparing CAT with FIT ( k = 11, g+ = 0.06, p = .28). However, easier CAT had positive effect compared with FIT ( k = 2, g+ = .22, p < .001). Certain modifications in CAT administration can provide positive psychological effects for test-takers.

Objective: As the number of mindfulness-based interventions (MBIs) for children has been constantly growing, there is a benefit to be derived for a comprehensive study that gathers what mindfulness activities have been reported to be effective at particular developmental stages, and how these practices have been modified to make them age-appropriate. Method: To address this problem, the content of twenty-six (cluster-) randomized controlled studies were analysed to identify any quantitative and qualitative differences. Results: The duration of MBIs varied greatly ranging from 4 to 25 weeks, 8 to 144 sessions, and 3 to 45 hours, with session duration from 3 to 90 minutes, which is an important factor to take into account. However, there were no age group differences due to number of sessions or program length. MBIs for early childhood were more likely to use mindful movement practice, psychoeducation, and story-based context. In case of other components, such as breathing awareness or working with thoughts and emotions, qualitative differences were found between early and middle childhood regarding how the activities were implemented age appropriately. Conclusions: The present study offers practical implications and distinguishes differences in mindfulness activities for early and middle childhood. Important developmental considerations have been raised for future program developers and practitioners.
