Because emotion knowledge and language skills each contribute to children's success in school and life, the Feeling Thinking Talking (FTT) intervention combines the advancement of language skills and of emotion knowledge in teachers’ child‐directed conversations. Teachers from centers of early childhood education in Germany were taught language support strategies (LSS) and how to apply them during emotion talk while reading picture books, while reminiscing about emotional events, and in everyday conversations with the children in their care. The evaluation of the FTT intervention entailed a comparison between the FTT group (N = 43) and a business‐as‐usual (BAU) control group (N = 67) with N = 110 children (M_age = 49.41 months, range = 33–66 months at T1) who were individually tested using objective tests on receptive vocabulary and emotion knowledge before (T1) and after the FTT intervention (T2), and in a follow‐up 3–6 months later (T3). After a multiple imputation procedure, mixed multilevel models indicated that the children taught by the FTT group teachers made faster progress in their emotion knowledge than their agemates in the BAU condition, especially in their knowledge of mixed emotions, when numerous covariates were controlled. Results suggest that young children's emotion knowledge can be promoted alongside with language skills by a teacher‐led intervention supporting child‐directed emotion talk in early childhood education. Discussion focuses on emotion talk as the mechanism for the transmission of emotion knowledge.

Objectives: In order to promote mindfulness in primary school, the Breathing Break Intervention was developed. This collection of short daily breath-based mindfulness practices was introduced to 15 teachers who delivered them up to 3 times a day to their students. Method: In a randomized controlled trial, 146 third and fourth graders (49% female) either received the intervention (n = 81) or participated in the active wait list control group (n = 65). Students were asked to nominate prosocial peers and to report on supportive peer relationships in their classrooms before (pretest) and after (posttest) the 9 weeks of the Breathing Break Intervention, and in a follow-up 5 months later. Results: Mixed multilevel models indicated a group × sex × posttest interaction (t(211) = 2.64, p < 0.01) suggesting that girls in the intervention group were rated to be more prosocial by their peers at posttest than at pretest and than girls in the active control group when children’s age and parents’ education were accounted for. Supportive peer relationships in the active control group deteriorated between pretest and posttest, which occurred immediately before the second school lockdown due to the COVID-19 pandemic, whereas they remained the same in the intervention group (t(223) = 2.56, p < 0.05). Both effects were not maintained at follow-up, probably due to children’s irregular school attendance during the lockdown. Conclusions: Introducing a short daily breathing practice in primary school classrooms seems to be effective in maintaining supportive peer relationships and in stimulating girls’ prosocial behavior.

Recent research confirms that climate change is having serious negative effects on children’s and adolescents’ mental health. Being aware of global warming, its dramatic consequences for individual and collective goals, and the urgent need for action to prevent further warming seems to be so overwhelming for young people that it may lead to paralyzing emotions like (future) anxiety, worries, shame, guilt, and reduced well-being overall. Many children and adolescents feel hopeless in view of the challenges posed by the transformations towards a sustainable future. Feeling powerless widens the gap between knowledge and action which in turn may exacerbate feelings of hopelessness. One of the tasks for parents, educators, and policymakers is therefore to empower young people to act against global warming, both individually and collectively. Psychological resources were identified as precursors of pro-environmental behavior. A theoretical model (and accompanying empirical research) is presented which elaborates on the links between self-efficacy, self-acceptance, mindfulness, capacity for pleasure, construction of meaning, and solidarity on the one hand, and subjective well-being and sustainable behavior on the other hand. This literature review suggests starting points for programs that aim to promote both psychological resources, subjective well-being, and individual and collective pro-environmental behaviors in young people.

Mindfulness-based interventions (MBIs) have been shown to improve children’s academic achievements. Because MBIs include different exercises (possibly with differential effects), the teacher-led Breathing Break Intervention (BBI) was developed which focuses exclusively on breathing exercises and body awareness. The short daily breathing practices of BBI were evaluated in terms of their effects on children’s performance in mathematics. In a randomized controlled trial, N = 140 third and fourth graders (49% female) either received BBI (IG, n = 81) or participated in an active control group (ACG, n = 59). Students took a standardized arithmetic test and teachers rated their mathematics performance before (T1) and after (T2) the nine weeks of BBI, and in a follow-up five months later (T3). A mixed multilevel model with a quadratic term of time indicated a significant interaction effect between group and time on the arithmetic test after controlling for working memory updating and parental educational attainment. IG children did not show a steeper linear increase but differed significantly from ACG children in their trajectory of arithmetic performance. At T3, IG children outperformed ACG children. A multilevel ordinal logistic regression of teachers’ ratings of students’ mathematics performance revealed no significant differences between IG and ACG. Results suggest that daily breathing exercises in primary school classrooms contribute to enhancing children’s performance in arithmetic.Preregistration: The study was preregistered at aspredicted.org (#44925).

Zusammenfassung. Das Emotionswissen von Kindern umfasst neben dem Ablesen von Emotionen aus Gesichtern anderer Menschen auch das Erkennen von externalen und internalen Ursachen von Emotionen sowie das Wissen über ihre Konsequenzen und Regulationsmöglichkeiten. Im deutschsprachigen Raum gibt es bisher kein Testverfahren, welches das Emotionswissen auf diese Weise differenziert und gleichzeitig reliabel und valide erfasst. Mit dem Adaptiven Test des Emotionswissens (ATEM) wird diese Lücke geschlossen. Der ATEM fragt in einem adaptiven Design 6 Teilaspekte des Emotionswissens ab, wobei die 32 Items in eine kinderfreundliche Geschichte eingebettet sind. Der nach der Item-Response-Theorie aufgebaute Test zeigt mit einer Gesamtstichprobe von N = 581 Kindern im Alter zwischen 3 und 9 Jahren gute psychometrische Eigenschaften. In einer Substichprobe von n = 254 Kindern im Alter zwischen 3 und 5 Jahren wurde der ATEM anhand von Korrelationen mit verschiedenen Variablen validiert. Insgesamt eignet sich der ATEM gut zur differenzierten Messung des Emotionswissens bei Kindern.
